Xiao Yuansi

Xiao Yuansi is Si Yuanbai’s third disciple, Li Chejing’s senior brother and Li Ximing’s alchemy master; Ximing is his only student. His pledge to protect the Li Family becomes a lasting commitment across generations, culminating in the pill he risks his health to deliver on the eve of Ximing’s Purple Mansion attempt. (Chapters 22, 98, 954–955 and 1603)

Biography

A generous senior from Qingsui Peak

Yuansi is Si Yuanbai’s third disciple and a seventh-layer Qi cultivator when Chejing joins Qingsui Peak. He welcomes the boy with a sword-technique scroll and carries his letters home. His first visit to the Li Family becomes practical assistance: he identifies their Snake Dragon Tree, refines its fruit into pills and installs a Misty Maze Formation on agreed credit terms. Generosity operates within obligations to his own clan, however. His Profound Scenery Spiritual Oath prevents him from disclosing the inherited Snake Essence Pill recipe, even while he freely teaches the Li how that oath works. (Chapters 22, 28 and 33–35)

As the sect sends the two disciples south, Yuansi arranges an exchange of family techniques for an Essence Gathering Pill sought for a Xiao relative. The comradeship becomes a more painful duty when Chejing entrusts him with gifts and the future care of his family. Yuansi recognizes the danger facing his junior, promises that the Li legacy will endure while he lives, and later receives Chejing’s sword records and request to return Qingche. Having reached Foundation Establishment himself, he brings Tongya the sword, resources and news that Chejing was sacrificed to demons. Unable to prevent that death, he expresses his guilt through continuing help rather than abandoning the pledge. (Chapters 76, 98, 127 and 167–169)

Keeping faith across the Li generations

His protection of the Li continues through cultivation advice, guarding their mountains and supplying alchemy knowledge. Chuchou’s account of Chi Wei’s past heroism unsettles the distinction between good and evil Yuansi learned from Yuanbai, yet it does not reconcile him to the loss of Chejing. When Tongya is caught in the great powers’ calculations, he presses Chuting to explain why the victim had to be Tongya. Chuting’s insistence that saving him would offend numerous Purple Mansion cultivators exposes the limits of Yuansi’s influence within his own family. (Chapters 208, 235, 285 and 366)

Yuansi recognizes the young Ximing’s aptitude for alchemy and gives the Li valuable help: he judges the child suited to pill refining and shares a Snake Essence Pill formula from his clan. His own progress has been slowed by the Xiao demand for continual production; by the Mount Wu expedition he has reached peak Foundation but still needs refinement before attempting Purple Mansion. He retrieves a shaman’s entrusted relics there, shares information with the Li and learns how little protection he can offer his old fellow disciples. News that Yuan Tuan has been missing for years leaves him desolate, suspecting Chuting arranged matters while keeping him ignorant. His loyalty to Ximing grows within that same tension between personal affection and clan strategy. (Chapters 352–353, 431, 686–688 and 730)

The Radiant Violet Pill and a vindicated mentorship

After Ximing reaches Foundation Establishment, Yuansi begins collecting Bright Yang materials for his future. Their teacher–student relationship is explicit when Yuansi meets him before the Purple Mansion attempt. Ximing’s rapid progress forces Yuansi to hurry, and he obtains Bright Sea Lotus and Triple Yang Radiant Qi Fruit before gathering the remaining ingredients in the Eastern Sea. Lacking a formula that directly guarantees aid in a Purple Mansion breakthrough, he refines pure Bright Yang Origin into the Radiant Violet Pill. Fearing Chuting might let Ximing enter seclusion before delivery, he injures himself to finish early and personally gives the pill to his disciple. He treats their meeting as a possible farewell, then bears Chuting’s criticism that the gift may encourage a fatal attempt. (Chapters 954–955 and 975)

Ximing succeeds, and Yuansi’s years of anxiety and public mockery give way to joy. The new Daoist Master bows to his teacher before the gathered families and personally welcomes him, affirming both gratitude and the continuing Li–Xiao bond. Yuansi remains modest about the success. In later old age, he has no accomplished descendants and Ximing is his only student; their affectionate meeting allows him to ask for help with the Yuan Family and news of Yuanbai. The disciple’s higher rank has reversed their public standing without extinguishing the care that began on Qingsui Peak. (Chapters 1034–1035 and 1603)

Appearance and personality

He has thick eyebrows and broad features, with a gentle, scholarly manner. Medicine pouches and a medicinal fragrance accompany his work. Sorrow over Chejing, Yuan Tuan and Yuanbai persists into old age; his concern for Ximing coexists with an awareness that affection can expose them both to political manipulation. By their final reunion his aging has become pronounced. (Chapters 22, 33, 730, 954–955 and 1603)

Abilities and cultivation

Cultivation and the Vermillion Sage

Yuansi follows the Immortal Dao cultivation path and reaches Qi Cultivation at twenty. Clan alchemy work delays his Foundation Establishment until about sixty. His immortal foundation, Vermillion Sage, enables him to understand plant speech: he identifies the Golden Bamboo Fruit from its response to flame, hears its complaints and uses a hand gesture to let Tongya hear them as well. Chuchou’s challenge to his moral assumptions also produces light from the foundation, apparently enhancing it, without establishing a new formal realm. By the Mount Wu expedition his Foundation cultivation has reached its peak, but he says he still needs refinement before Purple Mansion. His own later advancement to Purple Mansion is unconfirmed. (Chapters 208, 246, 431 and 686)

Alchemy and its restrictions

His alchemical expertise comes from the Xiao inheritance. He protects medicinal essence by harvesting with mana and using suitable containers, combines Snake Dragon Fruit with supplementary herbs and refines the mixture through Pill Flame and a furnace. One early batch yields eight pills; a later batch of seven fruits yields forty-five, of which he initially claims nine under their established arrangement before leaving the benefit to the Li. His oath forbids sharing the original recipe: breaking it would shatter his Profound Scenery and destroy his cultivation. He can provide instruction and later alchemy recipes within the permissions he has. (Chapters 33–35, 169 and 352–353)

Alchemy also carries costs beyond mana. Persistent family production burdens his own advancement, while access to rare materials limits what he can offer Ximing. The Radiant Violet Pill combines Bright Yang treasures into concentrated origin suited to his disciple, but Yuansi has no Purple Mansion breakthrough formula and never promises success. Finishing it ahead of the expected schedule injures him. Ximing eventually develops beyond his teacher’s traditional Jiangnan methods, while Yuansi remains a respected alchemist and devoted mentor. (Chapters 431, 954–955, 1243 and 1603)

Formations, artifacts and practical knowledge

Yuansi installs a Misty Maze Formation with six flags and explains its use to the Li, but that demonstration does not establish mastery of all formation arts. His flying shuttle supports travel, while medicine pouches preserve collected herbs despite their inability to fit within another spatial storage pouch. At Mount Wu, his gray-white medicine cauldron releases gray wind that strips the human livestock to blood and bone, then draws away the remains; Kongheng recognizes the skill as Shangqi Xun Wind. The destructive effect is demonstrated through the artifact, without a separate explained innate ability. (Chapters 34, 208 and 686)

Power progression

Relationships

• Li Chejing: His junior and friend, whose final commissions and family he promises to protect. (Chapters 98 and 167–169)
• Li Ximing: His only disciple; he refines the Radiant Violet Pill for Ximing and is publicly honored after the successful breakthrough. (Chapters 954–955, 1034–1035 and 1603)
• Si Yuanbai: His former master, whose whereabouts remain a concern in old age. (Chapters 22 and 1603)
• Yuan Tuan: His junior sister, whose disappearance exposes his inability to protect old companions. (Chapters 730 and 1603)
• Xiao Chuting: His clan elder, whose strategic priorities repeatedly conflict with his personal loyalties. (Chapters 366, 955 and 975)
• Xiao Chuchou: His uncle, whose account of Chi Wei challenges his inherited moral assumptions. (Chapters 208 and 687)

Items

He temporarily keeps the Qingche Sword and returns it with Chejing’s other gifts; the sword refuses to be drawn by him. His flying shuttle, pill furnace, medicine cauldron and spatial medicine pouches serve travel, refining and herb collection. He gives the Radiant Violet Pill to Ximing, while the Bone Carving Skin Exchange tablet recovered at Mount Wu is something he shares for examination, without demonstrated personal mastery of its technique. (Chapters 34–35, 167–169, 208, 686–687 and 954)
