Immortal Herb

Biodata

Background

Ancient herbological texts record Immortal Herbs, though Yue Guan had searched for many of the plants in his reference book without ever finding them. His collection included an entry for the Singular Velvet Sky Chrysanthemum, an herb matching his martial soul and capable of accelerating his breakthrough to Titled Douluo 10.

Su Mu located a large collection of Immortal Herbs at the Ice and Fire Yin Yang Well in Sunset Forest. The valley’s dual crimson-hot and icy-blue springs create an extraordinary environment for their growth 11.

Rather than reserving the herbs for himself, Su Mu matched specimens to his companions’ martial souls, bottlenecks, poison afflictions, and cultivation needs. Their absorption transformed several Spirit Hall members’ strength and future potential 11 14 15.

Immortal-grade spirit medicines are produced in only a handful of secret realms, including the Ice and Fire Yin Yang Well. High-grade medicinal treasures are scarce and grow extremely slowly. When presenting herbs to Chen Jianjun and Chen Xin, Su Mu described them as opportunities so rare that a specimen might grow only once in ten thousand years 93 96.

Su Mu’s stored herbs subsequently became resources for strengthening additional tournament teammates, supporting alchemical research, and securing the Seven Kill Sword lineage’s permanent residence in Spirit Hall 39 59 93 96.

Properties and Handling

• Immortal Herbs contain immense medicinal and Soul Power; compatible recipients may experience major cultivation breakthroughs, martial-soul evolution, or enhanced source power 11 14.
• An herb’s effects depend heavily on compatibility. Su Mu selected each specimen according to the recipient’s martial soul or condition 11 12 14.
• Simultaneous absorption can be dangerous. Bibi Dong lost consciousness after consuming two herbs, though their energies ultimately stabilized within her body 12.
• Su Mu delayed his own absorption until others had finished so that he could respond to unexpected danger 13.
• The Octagonal Mysterious Ice Grass and Infernal Delicate Apricot contain extreme ice and fire poisons. Either herb is unsafe alone; Su Mu consumed both together and entered the cold pool for body tempering, while the Life Goddess neutralized their poisons 14.
• Once the Ice Grass and Delicate Apricot are picked, they retain their effect for only ten breaths 14.
• Su Mu placed harvested herbs into jade boxes and later retrieved specimens from boxes kept in his Storage Soul Tool 11 39 59.
• Some Immortal Herbs can conceal a Soul Beast’s aura. Su Mu considered this possibility when planning to recruit Ah Yin, though her actual concealment was performed with the Life Goddess’s divine power 16 33.
• Medicinal intensity varies between specimens. The Myriad Crocodile Emperor Essence Fruit releases immense energy that can burden its recipient’s body, whereas Wansheng Lanhua and Azure Edge Sword Tassel Grass have comparatively mild medicinal properties 39 59 96.
• Before Tian Yue consumed the Myriad Crocodile Emperor Essence Fruit, Su Mu warned her about the strain of its energy and assured her that he and Ah Yin could manage complications 39.
• Most Soul Masters who obtain valuable spirit medicines consume them directly rather than refine them into pills, reflecting the continent’s lack of developed alchemical techniques and equipment 93.

Known Specimens

Appearance and Medicinal Character

• Singular Velvet Sky Chrysanthemum: A deep-purple, fragrance-free flower with enormous velvet-covered petals, a tall stem, and a protruding stamen whose tip carries faint golden light 11.
• Octagonal Mysterious Ice Grass: Resembles an eight-pointed white ice flower, crystal-clear like cold jade 14.
• Infernal Delicate Apricot: Resembles a fiery-red cabbage with layered leaves that release waves of heat 14.
• Myriad Crocodile Emperor Essence Fruit: A fist-sized, oval, dark-gold fruit covered in fine crocodile-scale patterns. Its surface carries faint golden radiance, and it gives off a heavy, primordial scent. Tian Yue initially found it sweet before its medicinal power erupted 39.
• Wansheng Lanhua: A translucent jade-green plant with a main stem resembling Blue Silver Grass, layered petals, and turquoise-lustrous leaf veins. Its fresh botanical fragrance accompanies continuously forming dewdrops, which produce short-lived blue silver sprouts upon touching the ground 59.
• Sky-Splitting Sword Lotus: A silver-gray, single-petaled lotus whose petal resembles cold iron. Tiny sword gleams shimmer along its edges, while faint golden light glows at its center 96.
• Azure Edge Sword Tassel Grass: Possesses nine long, narrow azure leaves with snowy tips. Its leaves produce a soft sword-tassel-like chime when moving and release faint wisps of sword energy 96.

Power Progression

Immortal Herbs do not have a documented cultivation sequence of their own. Their progression in the story is reflected in the increasingly varied advancements and applications achieved through their medicinal power.

Notable Effects

Cultivation Breakthroughs

• Dugu Bo, Yue Guan, and Gui Mei each reached Rank 90 after absorbing their respective Immortal Herbs, requiring only a final soul ring to become Titled Douluo 14.
• Qian Xunji used the Aromatic Silk Beauty to break through to Titled Douluo ahead of schedule 15 17.
• The herbs enabled several Spirit Hall powerhouses to pursue Hundred-Thousand-Year soul rings and entry into the Worship Hall 18 20.
• Tian Yue reached Rank 39 after absorbing the Myriad Crocodile Emperor Essence Fruit, placing her one level away from the Soul Ancestor bottleneck 39 40.
• Ah Yin reached Rank 49 through Wansheng Lanhua. She subsequently advanced to the Soul King realm during the tournament period 60 63.
• The sword-compatible herbs offered to Chen Jianjun and Chen Xin were specifically selected to overcome their Rank 97 and Rank 89 bottlenecks. Both began absorption, but their promised breakthroughs had not yet been shown 96.

Martial Soul Evolution

• Dugu Bo’s Jade Phosphor Serpent Emperor evolved after his poison was cured 14.
• Bibi Dong’s two Spider Emperor martial souls became mutually compatible, allowing the possibility of a Self Martial Soul Fusion Skill 13.
• Su Mu’s Wish Angel and Destruction Angel were both substantially strengthened, and the Life Goddess suggested developing a fusion skill between them 14.
• Hu Liena’s Demon Fox visibly evolved from one tail to three 14.
• Dugu Xin’s martial soul evolved into the Jade Phosphor Flood Dragon following the herb expedition and his subsequent soul-ring acquisition 14 15.
• Bibi Dong retained her martial soul’s original form while gaining the ability to extend its spider legs from her back. These legs also fused with her Eight Spider Lances External Soul Bone 38.
• Tian Yue’s Golden Crocodile King evolved into the Golden Crocodile Emperor. The dark-gold crocodile became brilliantly golden, developed curved horns and ancient scale patterns, and gained stronger source power and imperial pressure over other beast martial souls 40.
• Wansheng Lanhua strengthened Ah Yin’s Blue Silver Emperor origin and increased her natural affinity with plants 60.
• Yue Guan’s improved martial-soul quality raised his potential beyond its former limits; the narrative considered Rank 97 or Rank 98 a possible future attainment rather than a completed advancement 20.

Physical Transformation

• Su Mu completed Ice and Fire Body Tempering after a day and night in the Ice and Fire Yin Yang Well, significantly strengthening his physique and aura 15.
• Tian Yue’s first soul ring had previously increased in age through Su Mu’s Whale Rubber body-tempering method; after witnessing the herbs’ effects on others, she requested an Immortal Herb for herself 17 38.
• Bibi Dong reported that consuming two Immortal Herbs had greatly strengthened her physique 19.

Fusion Skills and Domains

• The Life Goddess confirmed that Bibi Dong’s two herbs had already provided sufficient foundation for Self Martial Soul Fusion. With guidance, spiritual power bridging the two origins, and additional divine assistance at a bottleneck, her Death Spider Emperor and Soul Devouring Spider Emperor successfully resonated and fused 43 44 45.
• Bibi Dong’s resulting fusion took a humanoid form resembling a female Su Mu because the Life Goddess deliberately altered its appearance, rather than because the herbs inherently dictated that form 45.
• Gui Mei explicitly attributed his insight into a self-created soul skill and the awakening of his personal Gui Mei Domain to the Immortal Herbs he had received 46.

Story Role

• Su Mu acquired Yue Guan’s herbological reference book before leading Bibi Dong, Xie An, Hu Liena, Yue Guan, Gui Mei, Dugu Bo, and Dugu Xin to the Ice and Fire Yin Yang Well 10 11.
• The discovery of the herb valley allowed Su Mu to cure the Dugu family’s hereditary poison and secure Dugu Bo’s loyalty to Spirit Hall 11 14.
• The widespread distribution of Immortal Herbs elevated multiple Spirit Hall members, strengthening its elders and future Worship Hall candidates 14 18.
• Su Mu later collected the remaining herbs from the well before returning to Spirit Hall 15.
• Bibi Dong’s absorption drew the Evil God King’s attention and an instruction to kill the Dark Demon Evil God Tiger, while the Rakshasa God offered a separate opportunity in Slaughter City. Su Mu advised her to pursue the superior Evil God King inheritance rather than the Rakshasa path 12 13.
• Su Mu agreed to give Tian Yue an herb on the condition that she cause less trouble and follow his instructions. Her subsequent evolution deeply impressed Golden Crocodile Douluo, who thanked Su Mu and remembered the favor 38 39 40.
• Qian Daoliu later reminded Qian Xunji that his Rank 93 strength was partly made possible by Su Mu’s Immortal Herbs, countering his son’s claims of being destined to surpass the divine ancestors 37.
• Su Mu gave Ah Yin Wansheng Lanhua to strengthen her foundation and accelerate her approach to Soul King, extending the benefits of his herb collection to the team’s seventh member 59 60.
• Qian Xunji and Qian Daoliu proposed offering two herbs to Chen Jianjun and Chen Xin as incentives to remain in Spirit Hall. The promised advancement persuaded the father and son to accept, bringing the Seven Kill Sword lineage into Spirit Hall’s sphere 94 96.
• After the sword masters began absorbing their herbs, Qian Daoliu planned to appoint Chen Jianjun as Eighth Worship after the tournament and arrange a Hundred-Thousand-Year soul-beast hunt for Chen Xin once he broke through 96.

Alchemical Applications

Su Mu proposed using Immortal Herbs from the Ice and Fire Yin Yang Well as core ingredients for top-grade pills. This was a planned application rather than an accomplished refinement. He arranged to study alchemy with the Undying Family for half a year after the Soul Master Tournament, and Yue Guan obtained permission to observe any future refinement using the herbs 92 93.

The scarcity and slow growth of high-grade medicinal plants contributed to the continent’s undeveloped alchemy. Ordinary herbs lacked sufficient potency, while valuable spirit medicines were usually consumed directly. The absence of extraction and pill-formation techniques, medicine cauldrons, and stable fire-control methods further limited their use as ingredients 93.

Su Mu also recognized that pills which forcibly increase Soul Power can damage a Soul Master’s foundation and reduce future cultivation potential. His proposed research sought to build an alchemical system, while his broader interest in distributing medicinal knowledge was linked to helping others and obtaining Power of Faith 60 93.
