Background & History

Early Life

Xia Mu was a transmigrator born to Xia Feng and Liu Yuer in Greenwood Town. Both parents served the Spirit Hall as deacons, while Xia Mu grew up with knowledge and ambitions far beyond his age. At six, Liu Yuer personally awakened his martial souls. 1

He inherited Xia Feng's Arm Bone martial soul and Liu Yuer's Dragon-Pattern Sword, but his Hextech System transformed them. His arm bones evolved into a complete skeletal Body Martial Soul, while the Dragon-Pattern Sword became the Light-Hiding Sword, an ultimate light-attribute martial soul with the sealed sword spirit Radiant Sacred Dragon. 1

Xia Mu initially concealed the sword's ultimate attributes from his mother, describing its unusual properties as a martial-soul inheritance. Liu Yuer told him of an ancient belief that a soul master's nine rings are heaven-given trials through which one may uncover a martial soul's origin and gain the qualifications for godhood. Xia Mu had already set his sights on that possibility. 2

Early Cultivation

Xia Mu immediately pursued an unusually aggressive cultivation path. He identified the uses of high-year whale glue, created a body-tempering medicinal bath, and used these resources to reach Level 10 within a day of awakening. 3

With Xia Feng and Liu Yuer's help, he hunted and absorbed soul rings far beyond ordinary limits: a 650-year first ring, a 1,200-year second ring, and a roughly 6,000-year third ring. He also designed a compound bow, used black powder against the Shieldblade Monster clan, and treated soul-beast hunts as calculated operations rather than straightforward battles. 4 9 17

Ice and Fire Yin-Yang Well

After learning of the Ice and Fire Yin-Yang Well, Xia Mu devised a plan to draw away its 60,000-year Queen Medusa guardian. Xia Feng acted as bait while Liu Yuer carried Xia Mu into the well; Xia Mu harvested all fifteen peerless immortal herbs and numerous Ninth-Grade Great Medicine Kings before the family escaped. 22 23

He distributed immortal herbs to his parents, using their properties to improve their martial souls and cultivation. Xia Mu consumed the Primordial Unity Immortal Herb and Full Moon Wearing Autumn Dew, reaching Level 40, gaining Fiery Golden Eyes, and advancing his spiritual power to the Spiritual Abyss Realm. 23 24

The Ice and Fire Yin-Yang Well subsequently became Xia Mu's private medicinal garden and a secure cultivation site for his allies. He planted the immature Crystal Blood Dragon Ginseng there to mature it into an immortal herb, while its unique environment enabled the rapid growth of further spiritual medicines. 29 42 79

As his organization expanded, Xia Mu continued to use the well to cultivate medicinal treasures and strengthen followers. He later entrusted Yue Guan with a hundred-thousand-year Blue Silver Emperor seed for cultivation there. 109 125

Slaughter City

At Level 50, Xia Mu entered Slaughter City under the identity Dugu Qiubai to gain genuine life-and-death combat experience and pursue the Killing God Domain. Over a year and a half, he became known as the Sword Demon, developed the Dugu Nine Swords, and completed one hundred victories in the Hell Slaughter Arena. 29 30

During the Hell Road trial, Xia Mu defeated the Dark Gold Three-Headed Bat King, acquired its external soul bone, and later defeated the Ten-Headed Fiery Sun Serpent through clone-assisted hit-and-run tactics. He returned to Heaven Dou City at Level 57 after nearly two years away. 30 31

Expansion of the Xia Family

After returning, Xia Mu helped Liu Yuer refine the Ten-Headed Fiery Sun Serpent's inner core, causing her martial soul to evolve into Crimson Sky. He also distributed rare medicines and the serpent's remains among the Dugu Family, deepening Dugu Bo's gratitude and securing his allegiance. 32 33

Xia Mu rescued Ling Yuan from the Blazing Sun Golden Crow Emperor and later brought her into his circle. He also met Shui Qingwu at Moonlight Pavilion, where her Ice Phoenix martial soul resonated with Ling Yuan's Fire Phoenix; the two women subsequently gained major improvements through joint cultivation at the Ice and Fire Yin-Yang Well. 34 36 39 42

He recruited Meng Shu, Chao Tianxiang, Ge Long, Zhi Lin, Bai Baoshan, and Meng Shenji to the Xia Family, personally granting each a Ten-Thousand-Year Medicine King to strengthen their foundations. Later, he entrusted Zhi Lin with the Heaven Dou ancestral residence and Ge Long with the Xia Family's merchant caravan. 46 52 80

Xia Mu later brought Tai Tan's Strength Clan, Niu Gao's Defense Clan, and Yang Wudi's Breaking Clan into his growing faction through displays of strength and offers tailored to their needs. He also sought to win over Bai He's Speed Clan. After his confrontation with the Clear Sky Sect, the Four Single-Attribute Clans were counted among his followers; he strengthened their leaders with rare medicines and promised further support. 106 109 114

Dark Demon Evil God Tiger

Xia Mu joined Xia Feng, Liu Yuer, Dugu Bo, and Ye Renxin in hunting the Dark Demon Evil God Tiger in the Icebound Forest. Drawn into the tiger's Life-and-Death Arena, he defeated the mutated soul beast with the Dugu Nine Swords and obtained the Evil God Orb, a mutated sixth natal soul ring, and the Dark Demon Evil God Hook external soul bone. 43 45 46

The Dark Demon Evil God Tiger's god-related origin caused Xia Mu's sixth ring to produce two soul skills rather than one. Its immense energy contributed to his rise to Level 66, while the Evil God Orb later became the source of his Ultimate Dark Soul Core. 45 46 58

Divine Transformation

After attaining Soul Sage cultivation, Xia Mu refined a hundred-thousand-year soul ring and continued using his knowledge of future opportunities to consolidate the Xia Family's power. He planned hunts for rare immortal herbs, gathered talented followers, and prepared his companions' cultivation paths with specific soul beasts and medicines in mind. 51 52 72

At the Ice and Fire Yin-Yang Well, the remnant souls of the Water Dragon King and Fire Dragon King entrusted Xia Mu with fragments of their godhood, god-level left and right arm bones, and million-year soul-ring inheritances. Xia Mu absorbed these gifts, reached Titled Douluo, and promised to revive the Dragon Kings after ascending to godhood. 58

By swallowing the Evil God Orb, Xia Mu formed an Ultimate Dark Soul Core alongside his Ultimate Light Soul Core, creating Yin-Yang Complementary Twin Soul Cores. The resulting divine power also triggered a Gold-Level Awakening in his Body Martial Soul, whose dark-golden skeletal structure developed flesh, blood, limbs, and a torso, though it still lacked complete organs and a brain. 58

Xia Mu subsequently began adding high-year rings to his Body Martial Soul. By his encounter with Bibi Dong, it bore three hundred-thousand-year rings; he later displayed additional red-toned rings while revealing his Peerless Douluo cultivation. After absorbing the Blood-Red Nine-Headed Bat King's ring, he observed another major transformation in the skeletal martial soul. 63 101 114 132

Consolidating Power

Xia Mu forced Ah Rou, a hundred-thousand-year Soft Bone Rabbit, to sacrifice herself to Ye Renxin, thereby elevating Ye Renxin to Titled Douluo. Xia Mu agreed to raise Ah Rou's daughter Xiao Wu after her gestation was complete, but later awarded Xiao Wu's hundred-thousand-year embryo, soul ring, and right arm bone to Gui Mei after the latter defected to him. 68 70 83

He accepted Zhu Qingyue as family after she chose genuine affection over the limited benefits of becoming a retainer. Her recognition by Lovesick Heartbreak Red proved her feelings, and the immortal herb evolved her martial soul into the Hell White Tiger. Xia Mu also accepted Nan Boer's feelings and used the Aromatic Silk Beauty immortal herb to evolve her Rouge Dragon into the Rouge Dragon Emperor. 70 71 72

Xia Mu defeated and recruited the former Spirit Hall elders Yue Guan and Gui Mei, turning them into medicine servants at the Ice and Fire Yin-Yang Well. He subsequently rewarded Yue Guan with the Velvet Vajra Chrysanthemum and Gui Mei with Xiao Wu's soul ring and soul bone, while Tuoba Xuanfeng submitted after witnessing the strength and resources available to Xia Mu's followers. 79 80 83

Xia Mu later confronted Tang Hao and Tang Xiao over Ah Yin, a hundred-thousand-year transformed Blue Silver Emperor. He defeated Tang Hao after the latter detonated his seven rings, claimed the Blue Silver Emperor seed, and pressured Tang Xiao to conceal the confrontation. Xia Mu also used the clash to sever the Four Single-Attribute Clans' remaining ties to the Clear Sky Sect. 108 109 114

Sea God Island and Bibi Dong

Xia Mu organized an expedition to Sea God Island to seek its divine trials and cultivation rewards for his companions. He had earlier intended to obtain the Vast Sea Cosmic Shroud and direct the Sea God's inheritance toward Shui Qingwu. 73 87 89 91

After his group subdued Spirit Hall members She Long and Ci Xue, Xia Mu identified Holy Maiden Bibi Dong's concealed twin martial souls and revealed his own cultivation to her. Rather than taking her treasures, he helped her obtain a Purple-Winged Demon Spider Emperor sixth ring and fuse with the Six-Winged Purple Light Wings external soul bone. He then brought her, She Long, and Ci Xue toward Sea God Island, explaining the opportunities its trials offered. 100 101 102

Xia Mu discovered that his Ultimate Dark Soul Core resonated with Bibi Dong's two spider-emperor martial souls, indicating that they could form a martial-soul fusion skill. He subsequently gave her rare soul bones and the Snow-Colored Swan Kiss immortal herb, encouraging her to pursue enough strength to control her own fate. 102 103

Holy Spirit Cult and Cultivation Methods

As the Holy Spirit Cult expanded, Xia Mu directed its combatants, clans, intelligence work, Spirit Pagoda construction, and Holy Spirit Chamber of Commerce. He assigned hunts suited to Bibi Dong and Zhu Qingyue, whose subsequent breakthroughs made them Peerless and Super Douluo respectively. He also used the prospect of rewards and advanced cultivation knowledge to motivate his followers. 124

Studying the inherited arts of the Four Single-Attribute Clans, Xia Mu spent over a year developing and perfecting Dragon Roar Iron Shirt, a method combining meridian circulation, soul power, and physical tempering. He also derived complementary hand, leg, and spear techniques. 118

Xia Mu shared his knowledge of Soul Cores with his companions and distinguished the relatively accessible Isotopic Resonance route from the more dangerous Yin-Yang Complementary route. Because his own twin cores arose under exceptional circumstances, he asked Bibi Dong to develop an Isotopic Resonance Soul Core Method that others could follow. He intended to make a basic method public while reserving fuller instruction for those close to him. 124 125

Appearance

By the time he became a Level 33 Soul Elder, Xia Mu had grown beyond his childish appearance into a spirited young man with a composed bearing. 17

• Sword-like brows and starry eyes. 17
• Carries the formless Light-Hiding Sword, whose jade-green dragon-mouth hilt manifests a transparent blade through soul power. 1
• Used a conical hat and the identity Dugu Qiubai while operating in Slaughter City. 29
• Possesses Dark Gold Bat Wings as an external soul bone. 30 31
• His Body Martial Soul's Gold-Level Awakening produced dark-golden jade-like bones, regenerated flesh and blood, and completed its limbs and torso. 58

Personality

Xia Mu is highly pragmatic and plans his cultivation around resources, information, and long-term foundation. He pursues whale glue, soul beasts, immortal herbs, and rare materials with a clear understanding of their strategic value, but refuses opportunities that he believes would compromise his future potential. 3 23 27

He is decisive and ruthless in battle. Xia Mu considers his sword a weapon of slaughter rather than a tool for arena competition, prefers real combat to staged spirit battles, and is willing to kill soul beasts, wolf bandits, and hostile soul masters without hesitation. 4 19 29

Despite this severity, Xia Mu is devoted to his family. He shares major gains with his parents, risks himself to help Dugu Bo, and repeatedly prioritizes raising his family's strength over keeping every resource for himself. 23 25 33

Xia Mu treats rare resources and talented people alike as assets that should be cultivated rather than wasted. He recruits former enemies through a calculated mixture of overwhelming force, rewards, and opportunities that their former factions could not offer. 46 79 80 83

Although he is capable of benevolence toward those who sincerely join him, Xia Mu is unsentimental toward opponents and soul beasts that obstruct his plans. His coercion of Ah Rou and later decision to use Xiao Wu's remains to reward Gui Mei demonstrate that he places his faction's advancement above conventional moral concerns. 68 70 83

His aid to Bibi Dong likewise combines concern for her future with an interest in winning a powerful ally. His treatment of the Four Single-Attribute Clans pairs substantial rewards with political leverage intended to secure their dependence on him. 101 103 109

Abilities & Skills

Hextech System

At his awakening, Xia Mu selected three Hextech traits from five options. 1

• Prismatic Evolution Tier — Evolved his Arm Bone martial soul into a full skeletal Body Martial Soul and his Dragon-Pattern Sword into the Dragon-Slaying Sword. 1
• Attribute Stacking — Grants one extra soul power level for every five gained naturally and 100 mental power for every ten levels gained. 1
• Enhanced Enchantment — Turned the Dragon-Slaying Sword into the ultimate light-attribute Light-Hiding Sword. 1

Light-Hiding Sword

The Light-Hiding Sword is Xia Mu's primary martial soul. Its blade is normally formless and manifests only through soul power; its hidden edge can pass through targets without immediately being noticed. 1

• Contains the ultimate light attribute and the initially sealed sword spirit Radiant Sacred Dragon. It also possesses near-ultimate metal properties. 1 2
• Can gather and disperse at will, allowing it to ignore physical defenses. 30
• Its extreme speed and penetration make it especially compatible with Xia Mu's offense-focused Dugu Nine Swords. 30
• After Xia Mu formed his Ultimate Light Soul Core, the sword spirit manifested as a Radiant Sacred Dragon, giving his weapon martial soul a beast-like form. 47
• The Radiant Sacred Dragon can manifest its power to destroy powerful domains, including Yue Guan and Gui Mei's Two Extremes Forbidden Domain. 79

Body Martial Soul

Xia Mu's second martial soul began as a complete skeletal Body Martial Soul. Its exceptional physical foundation enabled him to bear soul rings well beyond ordinary age limits and endure the strain of dual-martial-soul cultivation. 1 9 63

• Completed a Gold-Level Awakening after Xia Mu refined the Dragon Kings' divine inheritance. 58
• Its skeletal frame transformed into a partially completed body with jade-like bones, flesh, blood, limbs, and a torso. 58
• At that stage, it still lacked the five viscera and brain required for its complete transformation. 58
• Xia Mu possesses sufficient soul bones, external soul bones, and Soul Cores to regulate the conflict between his twin martial souls. 63
• Had acquired three hundred-thousand-year rings by the time Xia Mu revealed it to Bibi Dong. A later ring from the Blood-Red Nine-Headed Bat King triggered another transformation. 101 132

Soul Skill Arsenal

• Sword Dance — Third soul skill. Instantly increases attack power by 50% and strengthens subsequent soul skills. 17
• Frost Blade Manifestation — Fourth soul skill. Condenses a Flawless Sword Heart, enhances spiritual power, manifests Holy Spirit Sword Intent, and enables preemptive spiritual attacks. 28
• Myriad Swords Returning to the Sect — Fifth soul skill. An area-of-effect sword technique gained from the Dark Gold Three-Headed Bat King. 31
• Blade of Holy Light — One of the two skills granted by Xia Mu's mutated sixth natal soul ring from the Dark Demon Evil God Tiger. 45 46
• Evil God Protection — One of the two skills granted by Xia Mu's mutated sixth natal soul ring from the Dark Demon Evil God Tiger. 45 46
• Heaven-Shaking Thunder — Used to destroy the wolf bandits' lair. 11
• Yellow Springs Blood Sea — Domain skill obtained from the Blood-Red Nine-Headed Bat King's ring. 132
• Blood Demon Fist — Single-target burst skill obtained from the Blood-Red Nine-Headed Bat King's ring. 132

Dugu Nine Swords

Xia Mu developed the Dugu Nine Swords during his time in Slaughter City. The technique focuses on anticipating an opponent's movements and striking their vulnerabilities before they can react. 29

• Xia Mu described his sword path through sharp sword, flexible sword, heavy sword, wooden sword, and ultimately “no sword triumphing over sword.” 29
• Spear-Breaking Form — Interrupted Tang Hao's attack and pierced through his defense in a single exchange. 30
• Palm-Breaking Form — Exploited the Dark Demon Evil God Tiger's pounce, swipe, and bite patterns to defeat it within the Life-and-Death Arena. 45
• Relies heavily on Xia Mu's Flawless Sword Heart and superior spiritual perception. 29
• Xia Mu can wield his sword intent and Flawless Sword Heart to remain formidable even without relying on soul skills. 44

Fiery Golden Eyes

After refining the Full Moon Wearing Autumn Dew, Xia Mu cultivated Fiery Golden Eyes and advanced his spiritual power to the Spiritual Abyss Realm. 24

• Allows him to perceive extraordinary things and locate hidden targets, including the Mutated Black-Jointed Bamboo King. 24 27
• Raised his spiritual power to roughly 5,000 points. 24
• Let him overpower and assimilate the remnant will of a ten-thousand-year soul beast during ring absorption. 27
• Can see through the transformations of hundred-thousand-year soul beasts, allowing him to expose Xiao Wu's father. 54

Divine Slaughter Domain

Xia Mu obtained the Killing God Domain by clearing the Hell Road. After more than a year of refinement at Moonlight Pavilion, he gained complete control over it and could activate or withdraw it freely. 31 41

• Also referred to as the Divine Slaughter Domain. 41
• Its murderous aura can be restrained and tempered through Tang Yuehua's Noble Domain. 39 41
• Can suppress and imprison targets, including transformed soul beasts. 54

Soul Cores

Xia Mu possesses exceptionally condensed soul power due to the Primordial Unity Immortal Herb and his cultivation of Soul Cores. 24 48

• Ultimate Light Soul Core — His first Soul Core, formed from his ultimate-light soul power. It transformed his liquid soul power into solid, higher-quality essence. 47 48
• Ultimate Dark Soul Core — Formed when Xia Mu refined the Evil God Orb. 58
• Yin-Yang Complementary Twin Soul Cores — The combination of his Ultimate Light and Ultimate Dark Soul Cores. Their interaction produces true soul-power essence imbued with law attributes. 58
• Soul Core instruction — Taught his mother to form an Ultimate Fire Soul Core and later shared Soul Core cultivation principles with his companions. He tasked Bibi Dong with developing a more broadly usable Isotopic Resonance method, acknowledging that the circumstances behind his own twin cores were difficult to reproduce. 48 124 125

Dark Gold Bat Wings

Xia Mu acquired the Dark Gold Bat Wings from the Dark Gold Three-Headed Bat King during the Hell Road trial. The external soul bone later fused completely with his body. 30 31

• Enables high-speed flight. 31
• Clone — Can divide Xia Mu into ten thousand clones; if even one clone survives, he can preserve his life. 31
• Was crucial to his hit-and-run strategy against the Ten-Headed Fiery Sun Serpent. 31

Dragon Roar Iron Shirt

Xia Mu created Dragon Roar Iron Shirt by synthesizing the Four Single-Attribute Clans' inherited techniques with internal martial arts. It circulates qi, blood, and soul power through the body's meridians to unite physical tempering with cultivation; Xia Mu considered it particularly suitable for Body Martial Soul users. He had not yet perfected its treatment of the Eight Extraordinary Meridians. 118

• Perfect mastery gave Xia Mu an Indestructible Vajra Body and physical strength of 108,000 jin. 118
• Derived related techniques including Mighty Vajra Palm, Mighty Vajra Finger, Mighty Vajra Leg, and Mind-Intent Six Harmonies Spear. 118

Other Soul Bones

• Dark Demon Evil God Hook — External soul bone obtained from the Dark Demon Evil God Tiger alongside Xia Mu's mutated sixth soul ring. 45
• Fire Dragon King Right Arm Bone — A million-year god-level right arm bone bestowed by the Fire Dragon King. 58
• Water Dragon King Left Arm Bone — A million-year god-level left arm bone bestowed by the Water Dragon King. 58

Equipment & Items

• Wishful Hundred-Treasure Satchel — Storage soul tool purchased at the Heaven Dou Auction for 1.1 million gold soul coins. Xia Mu later used it to transport captured enemies, including Yue Guan, Gui Mei, and Tuoba Xuanfeng. 6 79 82
• Compound bow — Designed by Xia Mu for hunting the Golden-Scaled Armored Beast; he later used a compound bow himself against hostile soul masters. 4 32
• Black powder — Used as a concealed weapon to destroy the Shieldblade Monster clan. 9
• Aromatic Silk Immortal Herb — Carried into Slaughter City to purge the toxins from Bloody Mary. Xia Mu later gave the Aromatic Silk Beauty variant to Nan Boer to evolve her martial soul. 29 71 72
• Dragon Core — A rare auction acquisition that Xia Mu used to save Dugu Bo from poison backlash, creating a Poison Dragon Inner Core within him. 22 25
• Evil God Orb — The god-related orb left by the Dark Demon Evil God Tiger. Xia Mu ultimately swallowed it to form his Ultimate Dark Soul Core. 45 58
• Blue Silver Emperor seed — Claimed after his confrontation with Tang Hao and later entrusted to Yue Guan for cultivation at the Ice and Fire Yin-Yang Well. 109 125
• Four Single-Attribute Clans' inheritance manuals — Included forging, armor, alchemy, movement, and ring-related techniques. Their principles informed Xia Mu's creation of Dragon Roar Iron Shirt. 118

Relationships

• Liu Yuer — Mother. She awakened Xia Mu's martial souls, supported his dangerous ring hunts, and waited to obtain her seventh ring until he returned from Slaughter City. Xia Mu later gave her the Ten-Headed Fiery Sun Serpent's inner core, helping her martial soul evolve into Crimson Sky. She eventually reached Level 95 and became a Super Douluo. Xia Mu later considered how to improve her soul-bone set for her path toward godhood. 1 17 32 70 125
• Xia Feng — Father. Xia Mu treated him as the successful test case for a Body Martial Soul second awakening and regularly planned cultivation resources around improving his father's foundation. They fight and hunt together. Xia Feng later became a Level 95 Super Douluo. 7 23 27 73
• Dugu Bo — Family ally and beneficiary of Xia Mu's Dragon Core. Xia Mu saved Dugu Bo from soul-poison backlash; in return, Dugu Bo pledged allegiance and offered to follow Xia Mu's commands. 25 33
• Dugu Xin — Dugu Bo's son and a family friend. Xia Mu gave him a Ten-Thousand-Year Ninth-Grade Purple Lingzhi to strengthen his foundation and cultivation. 33
• Feng Yansha — Dugu Xin's partner. Xia Mu prepared a Ten-Thousand-Year Ninth-Grade Ginseng King for her to restore her innate foundation. 33
• Ye Renxin — Head of the Nine-Heart Begonia Clan. He gave Xia Mu a copy of the Immortal Herb Catalogue after recognizing his interest in immortal herbs. Xia Mu later arranged Ah Rou's sacrifice to help Ye Renxin become a Titled Douluo. 18 70
• Ye Ziyi — Ye Renxin's daughter. She initially asked Xia Mu to become her spirit-battle partner, but he refused because he sought only life-and-death combat. The two subsequently became engaged as part of a family alliance, with marriage deferred until Xia Mu reached eighteen; she was later counted among his wives. Xia Mu's gift of Aromatic Silk Beauty evolved her martial soul into the Sacred Heart Begonia. 19 37 72 102
• Tang Hao — Challenged Xia Mu in Slaughter City under the name Hammer King Tang Ritian. Xia Mu defeated him with one strike using the Spear-Breaking Form; Tang Hao later came to the Xia residence seeking revenge. In a subsequent clash over Ah Yin, Xia Mu defeated and severely injured him after he detonated all seven of his rings. 30 56 108 109
• Tang Xiao — Tang Hao's brother. After Xia Mu defeated Tang Hao, Tang Xiao accepted a concealed account of the confrontation to protect the Clear Sky Sect's reputation and took his injured brother away. 108 109
• Ling Yuan — A Blazing Academy graduate whom Xia Mu rescued from the Blazing Sun Golden Crow Emperor. She joined the Xia Family, became one of Xia Mu's closest companions, and shares a martial-soul resonance with Shui Qingwu. 34 36 39 42
• Shui Qingwu — A Tianshui Clan member and the mother of Shui Bing'er. Her Ice Phoenix martial soul resonates with Ling Yuan's Fire Phoenix, and Xia Mu provided betrothal gifts to secure her family's consent for her to cultivate with him. He intends for her to inherit the Sea God's power through the Vast Sea Cosmic Shroud. 39 42 52 73
• Zhu Qingyue — Former Star Luo fugitive and Xia Mu's prisoner. After choosing to become family rather than a mere retainer, she gained Lovesick Heartbreak Red's recognition, evolved into a Hell White Tiger martial soul user, and became one of Xia Mu's wives. She later reached Level 96 after obtaining a Dark-Gold White-Eyed Tiger King's ring and completing God Trial rewards. 55 70 71 124
• Nan Boer — Shui Qingwu's friend and a Rouge Dragon martial soul user. She confessed her feelings to Xia Mu, received the Aromatic Silk Beauty immortal herb, and evolved her martial soul into the Rouge Dragon Emperor. 71 72
• Bibi Dong — Former Spirit Hall Holy Maiden and fellow twin-martial-soul user. Xia Mu helped her obtain a sixth ring and an external soul bone, discovered a potential martial-soul fusion skill between them, and invested rare treasures in her cultivation.

• Yue Guan — Former Spirit Hall elder with the Singular Velvet Sky Chrysanthemum martial soul.

• Tai Tan — Strength Clan patriarch. He acknowledged Xia Mu as his master after being defeated, led his clan away from the Clear Sky Sect, and received medicine to improve his foundation. Xia Mu promised to help complete his soul-bone set and pursue Titled Douluo cultivation. 106 109
• Niu Gao — Defense Clan patriarch who pledged loyalty after weighing the opportunities Xia Mu offered his clan. His inherited defensive arts contributed to Xia Mu's later martial research. 106 109 118
