Appearance and Soul Form

Yao Lao's soul body is typically described as solidified and possessing a sense of physical density, often appearing with a thin layer of spiritual light on its surface 74. This spiritual light outlines his form and helps to restrain his vast spiritual power, indicating a recovery to a state close to the Spirit Realm 74. This phenomenon is attributed to a special manifestation that occurs when his soul touches the membrane of the Spirit Realm 74. When he demonstrates the manipulation of Heaven and Earth Energy, an illusory light and shadow can float on the surface of his body, with a point of light blooming in the center of his chest, from which his Soul Power radiates 134. During moments of intense spiritual impact, such as when Xiao Yan was refining the Azure Lotus Earth Core Flame, Yao Lao's illusory soul body could ripple, and a layer of green flame might even appear on its surface, indicating his soul being "ignited" before he protected it with his Bone Chilling Flame 108.

Specific details of Yao Lao's appearance and soul form include:

• Solidification: His soul body is described as being much more solidified than before, gaining a sense of physical density 74.
• Spiritual Light: A thin layer of spiritual light appears on the surface of his soul, outlining his entire form and restraining his spiritual power 74. This light is identified as Spiritual Qi, indicating his proximity to the Spirit Realm 74.
• Energy Manipulation: When manipulating Heaven and Earth Energy, an illusory light and shadow can float on his body's surface, with a central point of light in his chest from which his Soul Power disperses 134.
• Flame Manifestation: Under extreme spiritual stress, such as when his soul was "ignited" by the Azure Lotus Earth Core Flame, a layer of green flame could appear on the surface of his soul 108.
• Bone Chilling Flame Protection: He utilizes his Bone Chilling Flame to protect his soul, forming a layer of pale white flame around it 108.
• Facial Hair: He is depicted stroking his beard 74.
• Gestures: He often clasps his hands behind his back 74.

Personality and Traits

Yao Lao, a powerful and ancient soul, exhibits a complex personality characterized by profound wisdom, a mischievous streak, and a deep sense of mentorship. His vast knowledge of cultivation, alchemy, and ancient techniques is evident in his guidance of Xiao Yan, often surprising his disciple with the depth of his understanding 19 74 98. Despite his immense power and experience, he occasionally displays a playful or teasing nature, particularly in his early interactions with Xiao Yan 17. He is a stern but caring mentor, pushing Xiao Yan to his limits through rigorous training while also showing concern for his well-being and progress 25 134. Yao Lao is also shown to be deeply attached to his belongings, such as the Black Demon Cauldron, reacting with shock and dismay when Xiao Yan treats it carelessly 172. His past experiences, including his decision to cultivate the Flame Mantra at great risk, highlight a determined and ambitious side, driven by the pursuit of power and knowledge 98. He possesses a strong spiritual perception, capable of sensing hidden individuals and powerful entities 21 159. While generally composed, he can be overwhelmed by unexpected displays of knowledge, as seen when Xiao Yan reveals his understanding of soul realms 74. He also reflects on his past, hinting at personal relationships and responsibilities that shaped him 97.

Although Yao Lao initially claims that he wished to temper Xiao Yan's character by draining his Dou Qi, he eventually concedes that he had misjudged the situation. He recognizes that Xiao Yan's temperament is already exceptionally steady and apologizes for nearly damaging his cultivation 17. His concern can become frantic when Xiao Yan takes dangerous risks, particularly during cultivation breakthroughs or alchemical accidents, but it is consistently rooted in a desire to protect his disciple 43 180.

• Wise and Knowledgeable: Possesses extensive knowledge of cultivation methods, alchemy, Heavenly Flames, and ancient techniques, often surprising Xiao Yan with his insights 19 74 98 121. He can explain complex phenomena like spiritual light and the characteristics of different grade pills 74 97.
• Mischievous and Playful: Displays a teasing side, particularly when interacting with Xiao Yan, though Xiao Yan's calm demeanor often thwarts his attempts at amusement 17.
• Stern but Caring Mentor: Guides Xiao Yan with rigorous training methods, pushing him to improve and adapt, but also shows genuine concern for his disciple's development and safety 25 134. He provides crucial guidance on Xiao Yan's unique cultivation method and helps him refine his body 19 20.
• Dedicated to Mentorship: Willing to take Xiao Yan as a disciple, teach him alchemy, and share his vast experience, highlighting the importance he places on guiding others 20 172.
• Attached to Possessions: Shows strong emotional attachment to his belongings, such as the Black Demon Cauldron, reacting with shock when it is mishandled 172.
• Determined and Ambitious: His past decision to cultivate the Flame Mantra, despite the inherent risks, demonstrates a drive for power and a willingness to pursue challenging paths 98.
• Perceptive: Possesses powerful spiritual perception, allowing him to sense hidden individuals like Ling Ying and powerful entities such as the Fire Spirit 21 159.
• Reflective: Occasionally reflects on his past experiences and relationships, hinting at a complex personal history 97.
• Strategic Thinker: While sometimes surprised by Xiao Yan's practical mindset, he himself engages in strategic planning, such as his past intentions to cultivate the Flame Mantra 39 98.
• Adaptable Teacher: Employs unique teaching methods, sometimes allowing Xiao Yan to learn through experience and observation, even if it initially seems unconventional 172.
• Protective but Severe: He is willing to use harsh sparring, dangerous body-tempering methods, and painful refinement to advance Xiao Yan, yet intervenes immediately when an accident threatens his disciple's safety 134 174 180.
• Morally Discerning: Though capable of studying grim techniques, he rejects the use of living people as human-puppet materials and recalls his previous conflict with Old Man Mu Gu over cruel human-pill practices 164 165.

Abilities and Powers

Soul Power

Yao Lao possesses exceptional abilities related to soul cultivation, demonstrating a profound understanding and mastery of spiritual energy. His Soul Body is capable of solidifying and gaining a layer of spiritual light, indicating a recovery to a state close to the Spirit Realm 74. This spiritual light is identified as Spiritual Qi, which he can gather on a large scale and illuminate on the surface of his Soul Body 74. He attributes this phenomenon to touching the Spirit Realm membrane, a peculiar manifestation that did not occur during his lifetime 74. Yao Lao's knowledge of soul realms extends to the Mortal, Spirit, Heaven, and Emperor realms, and he is aware of ancient soul cultivation methods, though he admits that existing methods are often rudimentary and incomplete 74. He can also manipulate Heaven and Earth Energy by transforming his Soul Power across realms, allowing him to mobilize and precisely control power beyond his current cultivation level 134.

His Soul Power is sufficiently refined to probe ancient ruins, suppress lingering wills, identify concealed presences, and create incomplete Soul Techniques for Xiao Yan's cultivation 68 81 129. When necessary, he can possess Xiao Yan and project a Dou Zong-level aura that intimidates surrounding Magical Beasts 126. His incomplete soul form remains a major limitation, however, since intense alchemy, flame use, and combat can significantly deplete his spiritual strength 105 114 118.

• Applications:
  • Solidification of Soul Body and manifestation of spiritual light, indicating proximity to the Spirit Realm 74.
  • Large-scale gathering and illumination of Spiritual Qi on the Soul Body's surface 74.
  • Manipulation of Heaven and Earth Energy by transforming Soul Power, enabling control of power beyond his cultivation level 134.
  • Sensing the presence of powerful spiritual entities, such as a Fire Spirit, when possessing Xiao Yan 159.
  • Providing guidance and knowledge on ancient soul cultivation methods and the different soul realms 74.
  • Training Xiao Yan to improve his physical cultivation and adapt to incorporating Soul Power into combat 134.
  • Probing dangerous terrain and spatial distortions, though the Deep Ravine's distortions exceed his ability to investigate safely 81.
  • Suppressing lingering wills and teaching Xiao Yan a method for dealing with condensed mental energy 68.
  • Creating and providing Soul Techniques to improve Xiao Yan's Soul Power before combat training 129.
  • Projecting a Dou Zong-level aura through possession to suppress hostile Magical Beasts 126.
• Limitations:
  • The exact nature of the spiritual light phenomenon is not fully understood by Yao Lao, who describes it as peculiar 74.
  • Existing soul cultivation methods are generally rudimentary and incomplete, with fragmented information available only to a select few 74.
  • Separating a portion of his Bone Chilling Flame can weaken his Soul Body 45.
  • His Soul Body can be substantially depleted by advanced refinement; refining Purple Netherworld Flame Serpent Essence Blood causes it to fade by roughly thirty percent 114.
  • Going all out against superior opponents risks worsening his condition and forcing him into deep sleep 105.

Soul Possession

Yao Lao can enter and control Xiao Yan's body, allowing his disciple's body to temporarily wield strength, Soul Power, and combat experience beyond Xiao Yan's ordinary level 116 159. He uses possession carefully, as the state relies on his incomplete Soul Body and can expose Xiao Yan to dangerous opponents or excessive power 105 126.

• Applications:
  • Possessing Xiao Yan to capture and kill powerful Magical Beasts and coerce the Mist Snake into submission 116.
  • Releasing a Dou Zong-level aura in Ten Thousand Snake Valley to deter hidden Magical Beasts 126.
  • Taking control of Xiao Yan's body to confront and subdue the spiritual Netherworld Poison Fire 159.
  • Lending Xiao Yan his perception, flame control, and combat judgment during dangerous encounters 116 159.
• Limitations:
  • His incomplete Soul Body prevents him from freely sustaining his full past strength 105.
  • Heavy use of his power can worsen his condition or require a period of recovery 105 114.

Alchemy

Yao Lao is renowned as the Medicine Venerable, possessing extensive expertise in alchemy and the refinement of various pills and medicinal substances 43 174. He demonstrates a deep understanding of medicinal properties and their effects on the body, capable of creating potent elixirs for cultivation and recovery 45 91. His skills extend to reverse-engineering existing pills and developing new formulations to suit specific needs, such as the Blood Spirit Pill 91. He utilizes specialized equipment like the Black Demon Cauldron for refining, showcasing his mastery over the complex processes involved in pill concoction 43 172. Yao Lao also employs unique teaching methods in alchemy, sometimes guiding Xiao Yan through challenging tasks to impart deeper understanding 172.

Yao Lao can conduct large-scale and high-risk refinement even while existing as a Soul Body. He creates an enormous makeshift cauldron from a mountain to refine the Blood Origin Pill, refines soul origin into medicine for his own recovery, and intervenes decisively when Xiao Yan's mismatched Dou Qi causes an alchemical explosion 118 139 180.

• Applications:
  • Refining pills to aid in cultivation breakthroughs, such as those for advancing strength 43 91.
  • Creating medicinal liquids that strengthen and rebirth the body, imparting new abilities 45.
  • Reverse-engineering and modifying existing pills, like the Blood Spirit Pill, to create new formulations 91.
  • Providing pills to suppress fatigue and enhance energy during complex cultivation tasks 136.
  • Using specialized equipment like the Black Demon Cauldron for advanced refining processes 43 172.
  • Teaching complex alchemy techniques, such as the Crystal Fire Seal for refining Blood Qi 91.
  • Concocting massive, impure pills from souls as a teaching method to convey deeper alchemical principles 172.
  • Creating a mountain-sized Heavenly Flame cauldron for the Blood Origin Pill's refinement 118.
  • Refining Wu Protector's soul origin into a medicinal pill for his own recovery 139.
  • Teaching Xiao Yan methods for producing ruined pills and deliberately poisonous pill products 148.
  • Recovering a damaged Sixth Grade Azure Underworld Longevity Pill after Xiao Yan's cauldron explosion 180.
• Limitations:
  • Refining powerful substances, such as souls, can be a messy and unconventional process, potentially shocking others 172.
  • The process of refining can be intense and require significant focus, sometimes leading him to be engrossed in his work to the exclusion of other matters 172.
  • High-grade refinement places heavy strain on his Soul Body and may require extensive preparation and recovery 114 118.
  • Even with his guidance, foreign bloodline attributes and unstable flame control can produce unpredictable results during Xiao Yan's refinement 180.

Heavenly Flames and Fire Control

Yao Lao possesses the Bone Chilling Flame, a powerful Heavenly Flame with unique properties and a degree of spirituality 45 159. He can manipulate this flame with great precision, using it to subdue other powerful fire entities, such as a Dou Zong-level Fire Spirit 159. His control over flames is so advanced that he can separate portions of his own Heavenly Flame for others to refine 45. He also teaches Xiao Yan the intricate art of kneading different flames together to create powerful explosions, known as the Fire Lotus configuration, emphasizing the importance of flame compatibility 136.

The Bone Chilling Flame had already developed spirituality before Yao Lao subdued it. Its former Fire Spirit cultivated by exploiting its yin-yang nature to devour souls and absorb Fire Seeds, leaving the flame with unusual beast-shaped manifestations and great potential 159. Yao Lao can manifest its pale white fire as devastating offensive force, defensive protection, or an instrument of high-level alchemy 104 118 159.

• Applications:
  • Subduing powerful fire spirits and other entities with the Bone Chilling Flame 159.
  • Separating portions of the Bone Chilling Flame for others to refine, enhancing their own flames 45.
  • Teaching advanced flame manipulation techniques, such as the Fire Lotus configuration, which involves kneading different flames for explosive power 136.
  • Using the Bone Chilling Flame to envelop himself during pill refinement, demonstrating its utility in alchemy 43.
  • Explaining the spiritual evolution of Heavenly Flames and their potential to develop complete Spirit Bodies 159.
  • Freezing Hai Bodong's ice-attributed Dou Qi and converting the resulting frost into eerie icy flames 104.
  • Constructing vast flame formations and a mountain-sized refining cauldron for the Blood Origin Pill 118.
  • Protecting his Soul Body or Xiao Yan from destructive flame backlash 108 180.
• Limitations:
  • Separating a portion of the Bone Chilling Flame can weaken Yao Lao's Soul Body 45.
  • The Fire Lotus configuration is complex and potentially dangerous, requiring careful execution and compatible flames 136.
  • The consumption and limitations of powerful techniques, such as those involving Heavenly Flames, are a significant theme 159.
  • Extensive Heavenly Flame use can drain his Soul Body and worsen his unstable condition 105 118.

Combat Skills and Training

Yao Lao is an exceptionally experienced combatant and a stern, effective mentor 25 130. He employs a "stick education" method, pushing Xiao Yan to his limits through rigorous training and sparring sessions 134. He can use his full power in combat, demonstrating superior strength and perception even against skilled opponents 130. His vast battle experience allows him to predict opponents' moves and adapt to special situations 130. He also possesses knowledge of various Dou Techniques and can modify existing items into cultivation tools, such as bracelets that seal Dou Qi storage and output 26.

His current combat ability is highly variable because he must conserve his incomplete Soul Body. He estimates that he can normally use around a Two Star Dou Zong's strength, while the Bone Chilling Flame permits him to exchange several moves with a high-level Dou Zong 105. Later, his aura is sufficient to overwhelm Yan Luotian and greatly exceed that of a Five Star Dou Zong 179.

• Applications:
  • Engaging in intense sparring sessions to train and improve Xiao Yan's Dou Techniques and control over Heavenly Flames 130.
  • Demonstrating vast battle experience and the ability to predict opponents' moves 130.
  • Teaching adaptability in battle and how to deal with special situations 130.
  • Modifying torture devices into cultivation items, such as bracelets that seal Dou Qi 26.
  • Pushing students to their limits through powerful attacks and rigorous training to improve their defensive and offensive capabilities 25.
  • Guiding students in understanding and utilizing their unique cultivation methods, such as Xiao Yan's multi-elemental Dou Qi 19.
  • Using the Pale White Fire Ruler to force Xiao Yan to integrate Soul Power into practical combat 134.
  • Employing possession, Soul Power, and the Bone Chilling Flame to defeat or intimidate opponents above Xiao Yan's ordinary level 116 126 159.
• Limitations:
  • His training methods can be harsh and demanding, requiring resilience from his students 25 134.
  • The power gap between different cultivation realms means that even with superior experience, there are limits to what can be achieved against significantly stronger opponents 130.
  • Fully exerting himself risks destabilizing his incomplete Soul Body and sending him into deep sleep 105.

Crafting and Refinement

Yao Lao possesses skills in crafting and refining various items, extending beyond alchemy to include physical objects. He demonstrates expertise in using unique materials, such as Xiao Yan's Purple Cloud Wings, as a base for crafting more powerful artifacts 174. He understands the intricate processes involved in fusing materials and activating bloodlines, as seen when he strengthens Xiao Yan's wings with Essence Blood and Plume, leading to the activation of a Withered Moon Owl Bloodline 174.

• Applications:
  • Crafting and refining flying wings using specialized materials like Purple Cloud Wings 174.
  • Strengthening artifacts by incorporating powerful components, such as the Withered Owl Ape's Essence Blood and Plume 174.

  • Understanding the properties of rare medicinal ingredients and their effects on the human body 45.
  • Modifying suppression bracelets originally intended for Dou Wang experts into cultivation tools suitable for Xiao Yan 26.
  • Studying Magical Beast body-and-soul sealing methods and wing-refinement secret arts 82 172.
• Limitations:
  • The process of crafting and fusing can be painful and physically demanding for the recipient 174.
  • He can be vague about the details of risky procedures, sometimes leaving Xiao Yan to endure the consequences of an experimental refinement 174.
  • Incomplete secret-method records and deliberately obscure terminology can limit even Yao Lao's ability to reconstruct ancient techniques 172.

Poison Tempering and Puppet Arts

Yao Lao has sufficient technical knowledge to assess dangerous puppet methods and extract useful portions from them without accepting their cruelest applications. Though he rejects the use of living people as materials for human puppets, he recognizes that the Poison Tempering component of Nether Old Ghost's secret art can be adapted to help Xiao Yi Xian strengthen her body and control the Woeful Poison Body 164 165.

• Applications:
  • Identifying the independent Poison Tempering portion within a Poison Puppet secret art 164.
  • Guiding Xiao Yi Xian to use her own poison safely enough to temper and strengthen her body 164 165.
  • Developing cultivation solutions specifically suited to special physiques 164.
• Limitations:
  • The strength gained through Xiao Yi Xian's Poison Tempering remains temporary and lasts only while her Woeful Poison Body is active 165.
  • Yao Lao refuses to endorse methods that require living human materials or cruel Sacrificial Refining practices 164 165.

Mentorship of Xiao Yan

The relationship between Xiao Yan and Yao Lao is characterized by a profound master-disciple bond, evolving from an initial transactional agreement into one of deep mutual respect, trust, and affection. Yao Lao, a powerful alchemist and cultivator, acts as Xiao Yan's primary mentor, guiding him through the complexities of cultivation, alchemy, and combat. He recognizes Xiao Yan's extraordinary talent and potential early on, often pushing him to his limits with rigorous training methods and unconventional teaching approaches 25 172. Xiao Yan, in turn, demonstrates unwavering trust in Yao Lao's judgment, eagerly absorbing his vast knowledge and adapting to his unique instructional style, even when it involves challenging or seemingly bizarre tasks 172. This mentorship is central to Xiao Yan's rapid growth, enabling him to overcome significant obstacles and develop into a formidable cultivator and alchemist 20 71.

Their relationship began with Yao Lao's attempt to temper Xiao Yan by absorbing his Dou Qi. After acknowledging that Xiao Yan's stable temperament made the attempt misguided, Yao Lao apologized and offered cultivation resources 17. They then reached an explicit agreement: Yao Lao would help Xiao Yan cultivate the Flame Mantra and travel the continent, while Xiao Yan would seek a way to revive him after achieving sufficient strength 18. Xiao Yan later formalized the relationship by performing the master-disciple bow 20.

Specific instances of Yao Lao's guidance, training, or shared knowledge include:

• Initial Cultivation Analysis and Body Refinement: Yao Lao first identifies the chaotic Qi and blood circulation disrupting Xiao Yan's meridians, explaining the root cause of his cultivation issues. He then teaches Xiao Yan a portion of a body refining technique to improve his Dou Qi control and efficiency, marking the beginning of their formal master-disciple relationship 20.
• Introduction to Fen Jue and Heavenly Flames: Yao Lao offers Xiao Yan the Yellow Rank Low Level technique, Fen Jue, which possesses the unique ability to evolve by devouring Heavenly Flames. He demonstrates a Heavenly Flame to Xiao Yan, revealing the technique's immense potential and setting Xiao Yan on a path to acquire these rare flames 17.
• Resurrection Agreement: Yao Lao reveals that he is a dead soul seeking revival and entrusts the Fen Jue scroll to Xiao Yan as part of their agreement. Xiao Yan accepts despite the uncertain chance of success, establishing the foundation of their long-term partnership 18.
• Guidance on Unique Dou Qi Cultivation: Yao Lao discovers Xiao Yan's unique Dou Qi situation, where his three types (Fire, Wind, and Earth) interact to allow rapid replenishment. He explains the advantages and disadvantages of this method, emphasizing the need for aggressive attacks and careful Dou Qi management. He also suggests connecting Xiao Yan's special cultivation technique (Qi Cyclone) with Fen Jue to improve control and recovery 19.
• Alchemy Training and Skill Development: Yao Lao systematically trains Xiao Yan in alchemy, starting with beginner recipes and progressing to higher-grade pills. He guides Xiao Yan through refining a Third Grade medicinal paste, approving of his unconventional methods, and later helps him refine a Fourth Grade Three-Pattern Azure Spirit Pill, even suggesting modifications to its formula 27 52. He also provides the Green Medicine Cauldron for Xiao Yan's alchemy practice 27.
• Combat and Movement Technique Training: Yao Lao provides Xiao Yan with the heavy, Dou Qi-suppressing Xuan Heavy Ruler to enhance his physical training and endurance 21. He also tests Xiao Yan's progress with movement techniques like Instant Step, unleashing powerful attacks to push Xiao Yan's defensive and offensive capabilities, ensuring he can effectively utilize techniques like Eight Extremities Collapse, Breath Fire Palm, Wave Devouring Ruler, and Suction Palm 25.
• Advanced Cultivation Techniques and Principles: Yao Lao teaches Xiao Yan the Crystal Fire Seal technique, which Xiao Yan quickly masters after a single observation, to refine Blood Qi separately from his Dou Qi 91. He also provides an incantation that allows Xiao Yan to advance to the Fifth Layer of the Dou Ling realm and manipulate Heaven and Earth Energy 134.
• Strategic Combat Training: During sparring sessions, Yao Lao uses his full power, demonstrating vast battle experience and the ability to predict Xiao Yan's moves. He teaches Xiao Yan about dealing with special situations and the importance of adaptability in battle, highlighting the power gap between different cultivation realms 130. He also trains Xiao Yan to improve his physical cultivation and adapt to the feeling of Soul Power joining the battle 134.
• Soul Technique Instruction: Noticing that Xiao Yan's rapidly improving body and Dou Qi had outpaced his ability to coordinate his own Soul Power, Yao Lao creates a Soul Technique and prescribes combat training to restore that balance 129.
• Unconventional Teaching Methods: Yao Lao employs unique and sometimes shocking teaching methods, such as instructing Xiao Yan to cook souls in the Black Demon Cauldron. This seemingly bizarre task ultimately leads Xiao Yan to understand deeper principles of alchemy and cultivation, even if it initially appalls Yao Lao himself 172.
• Sharing Knowledge of Soul Cultivation: Xiao Yan demonstrates knowledge of soul realms and ancient soul cultivation methods, surprising Yao Lao and indicating a shared intellectual curiosity beyond conventional cultivation 74.
• Three Mysterious Transformations Guidance: Yao Lao explains the dependence of the Heavenly Fire Three Mysterious Transformations on powerful flames, helps Xiao Yan assess the reappearance of his golden Qi, and identifies its similarity to the Dou Di Bloodline 163.
• Refinement of Purple Cloud Wings: Yao Lao directs Xiao Yan through the dangerous procedure of strengthening Purple Cloud Wings with Withered Owl Ape materials. Although he teases Xiao Yan throughout the ordeal, he monitors the disciple's condition and successfully helps trigger the Withered Moon Owl Bloodline phenomenon 174.
• Safety During Advanced Alchemy: When Xiao Yan's bloodline attribute causes foreign Dou Qi to enter a Sixth Grade pill refinement and trigger an explosion, Yao Lao immediately shields him with Heavenly Flames and retrieves the damaged pill 180.
• Recognition of Potential: Yao Lao consistently recognizes Xiao Yan's extraordinary talent and rapid progress, expressing optimism about his potential to reach high cultivation grades and even questioning if Xiao Yan is an ordinary person after he refines a Seventh Grade Pill 71 91.

Xiao Yan and Yao Lao share a deep master-disciple relationship, characterized by guidance, trust, and occasional playful bickering 104 134. Yao Lao acts as a mentor, providing Xiao Yan with crucial training, knowledge, and support in his cultivation journey 134 172. He guides Xiao Yan through complex pill refining processes, teaching him advanced techniques and the nuances of using Heavenly Flames 68 118. Yao Lao often employs unique teaching methods, sometimes causing Xiao Yan to understand deeper meanings through seemingly unconventional tasks 172. He expresses concern for Xiao Yan's safety, warning him about potential dangers and backstabbing 59 104. Yao Lao also recognizes Xiao Yan's astonishing talent and rapid progress, acknowledging his potential to challenge powerful elites 71. Their relationship is built on mutual respect and cooperation, especially when facing challenges like a Lightning Tribulation during pill refining 118. Despite his protective nature, Yao Lao sometimes keeps details from Xiao Yan, leading to moments of caution and hesitation from the disciple 174.

Their bond is also founded on a direct agreement: Yao Lao guides Xiao Yan in the Flame Mantra and other paths to power, while Xiao Yan intends to seek Yao Lao's eventual revival 18. Xiao Yan's eagerness to avenge Yao Lao and his insistence that his teacher's enemies are also his own demonstrate the depth of his loyalty 39.

Xun Er

Xun Er holds a significant place in Xiao Yan's life, with their relationship characterized by unspoken affection and longing 71. Xiao Yan shows concern for her well-being, taking her out shopping and ensuring her care 121. Xun Er, in turn, displays deep affection for Xiao Yan, anxiously waiting for his return and missing him deeply when he is absent 71. Her feelings for him are strong enough to evoke jealousy towards other women, such as the Little Fairy Doctor 121.

Little Fairy Doctor

The relationship between Xiao Yan and the Little Fairy Doctor evolves from a tense dynamic to a more relaxed and friendly one. Initially, the Little Fairy Doctor feels burdened by Xun Er's hostility towards her, and Xiao Yan shows interest in her 121. However, after Xiao Yan takes her shopping and displays kindness and generosity, she begins to see him in a new light 77. She expresses confusion and a lack of understanding regarding Xiao Yan's intense pursuit of knowledge and cultivation, highlighting a difference in their perspectives 172.

Hai Bodong

Xiao Yan and Hai Bodong's relationship is primarily transactional, built on mutual benefit and respect. Hai Bodong, a sealed Ice Emperor, agrees to help Xiao Yan break his seal in exchange for a pill 104. In return, he provides Xiao Yan with valuable information, including a detailed map of the Tagor Desert and hints about ancient existences 105 121. After receiving a pill from Xiao Yan, Hai Bodong regains his strength, though his realm remains damaged 121. Their interactions demonstrate a cooperative dynamic where both parties gain from the exchange 105.

Amethyst Winged Lion King

Xiao Yan and the Amethyst Winged Lion King develop a master-pet relationship marked by loyalty and protection 115. Initially, the Lion King is hesitant and even threatens Xiao Yan when he tries to use its cave residence 59. However, enticed by the offer of a Sixth Grade Pill, it agrees to let Xiao Yan use its cave 59. Xiao Yan later shows a protective side towards the Lion King, saving it from being besieged by other magical beasts 115. The Lion King, in turn, demonstrates loyalty, assisting Xiao Yan in capturing Yan Luotian and expressing concern for his safety 170.

History and Background

Yao Lao's past is gradually revealed through his interactions with Xiao Yan and his extensive knowledge of cultivation, alchemy, and the broader Dou Qi Continent. Early in his mentorship of Xiao Yan, Yao Lao demonstrates his vast experience by identifying and explaining Xiao Yan's unique Dou Qi situation, where three types of Dou Qi (Fire, Wind, Earth) interact to allow rapid replenishment 19. He also reveals his ability to modify torture devices into cultivation tools, such as bracelets that seal Dou Qi storage and output, showcasing a history that includes unconventional methods 26.

His expertise extends to alchemy, where he guides Xiao Yan from refining a Third Grade pill to a Fourth Grade pill, the Three-Pattern Azure Spirit Pill, and even suggests modifications to its formula 52. This deep understanding of alchemy is further highlighted when he teaches Xiao Yan about the characteristics of different grade pills and reflects on his own past experiences in the field 97. Yao Lao's past plans included cultivating the Flame Mantra, a technique that required Heavenly Flames, indicating a long-standing pursuit of powerful cultivation methods 98. He also developed a Poison Pill method, which required a Heavenly Flame for refinement, to help those with a Poison Body 98.

Yao Lao's connections and knowledge are not limited to cultivation and alchemy. He possesses a powerful spiritual perception, demonstrated when he senses Ling Ying, a hidden protector, in Xiao Yan's courtyard 21. He also hints at having connections with one of the Emperor Clans, though he avoids providing specific details, suggesting a past involved with powerful, ancient lineages 26. His wisdom is evident in his ability to summon Spiritual Qi to replenish his soul, a feat that showcases his strong soul essence 39.

A significant revelation about Yao Lao's past comes when he shares his intention to cultivate the Flame Mantra, a technique he had planned to use himself, which required the rare and powerful Heavenly Flames 98. He even knew the location of a Heavenly Flame, the Netherworld Poison Fire, near the Gama Empire 98. This ambition to master such a formidable technique underscores his pursuit of power and strength, even at great personal risk 98.

Later, Yao Lao's soul body solidifies and gains a layer of spiritual light, resembling the Spirit Realm. He attributes this phenomenon to a peculiar manifestation of touching the Spirit Realm membrane, though he cannot fully explain it 74. This event, combined with Xiao Yan's knowledge of soul realms (Mortal, Spirit, Heaven, Emperor) and ancient soul cultivation methods, suggests that Yao Lao's own spiritual journey has been profound and perhaps unconventional 74. Despite his vast knowledge, Yao Lao shows reluctance to break his ancestral precepts when Xiao Yan proposes refining Wu Protector's soul to aid his recovery, indicating a deep-seated respect for tradition and a moral compass that he is hesitant to compromise 138. His unique teaching methods, such as instructing Xiao Yan to cook souls in the Black Demon Cauldron to concoct a massive, impure pill, reveal a pragmatic and unconventional approach to mentorship, often leading to deeper understanding for his disciple 172.

Yao Lao was once a renowned alchemist whose reputation extended across the continent. He describes the alchemists of the Jia Ma Empire and its surrounding northwest region as far beneath his former standing, and he possessed the Black Demon Cauldron as his personal medicinal cauldron 20 43. By the height of his former life, he had reached the peak of the ninth turn and possessed techniques whose sophistication greatly exceeds what his weakened present Soul Body can freely employ 159.

At some point after losing his body, Yao Lao became a soul residing within Xiao Yan's ring. He explains that he has been dead for a long time and that the revival method recorded by Fen Jue is an uncertain gamble rather than a guaranteed path 18. His current condition remains incomplete; although he can produce formidable combat power, excessive exertion risks deepening his weakness or forcing him into prolonged sleep 105.

Yao Lao spent much of his living life traveling throughout the continent. He has crossed Central State in search of rare items, understands the use of public Space Channels, and has personally investigated many ancient ruins and mechanism arts 82 126. During an attempt to repair abandoned Space Channels, he dealt with a resentful remnant soul, was swept into Space Turbulence, and arrived at the Heavenly Serpent Mansion, establishing an unclear connection with that faction 166.

His history with Heavenly Flames is particularly significant. Before Yao Lao subdued it, the Bone Chilling Flame had already formed spirituality and pursued its own cultivation path by devouring souls and absorbing Fire Seeds through its yin-yang nature 159. This history gives Yao Lao unusually deep insight into spiritual Heavenly Flames, allowing him to recognize the threat posed by the nearly intelligent Netherworld Poison Fire and suppress it after awakening within Xiao Yan's body 159.

Yao Lao's former relationships remain partially obscured. He reacts evasively when Xiao Yan questions whether he once had someone with whom he nearly formed a relationship, suggesting that his attention to his disciple Han Feng and his other responsibilities may have interfered with his personal life 97. He also bears a strong ethical aversion to Old Man Mu Gu's cruel methods of Sacrificial Refining and human-pill creation, which later informs his rejection of using living people to make Poison Puppets 164 165.
