Background / History

Xuan Chengzi was once a disciple of the Tianyin Sect. While his master was in seclusion, he betrayed the sect by stealing half of the Spirit Seed Creation True Scripture and the Five Elements Refinement Technique, then fled to Tianzhou. His fellow sect members, including Su Ye, pursued him for the stolen techniques. 17 66 103

Using the incomplete Spirit Seed Creation True Scripture, he refined more than one hundred spirit seeds and elevated his Spirit Root to top-grade quality. The incomplete scripture also damaged his Spirit Root and drastically reduced his lifespan, leaving him with less than three months to live in one documented reset. 67 101 102

He established a concealed cave dwelling and captured children as “Medicinal Seeds” for pill refinement. Qin Yang was among his captives: Xuan Chengzi gave him a Soul Locking Pill, forced him to test a Water Spirit Pill refined from a girl with a Water Spirit Root, and later accepted him as a disciple for use in pill refinement. 3 4

Xuan Chengzi regarded Qin Yang as both a useful resource and a potential successor, but Qin repeatedly escaped or turned against him across successive resets. When Qin led Su Ye to the cave dwelling, Xuan Chengzi recognized the betrayal immediately and attempted to kill him after breaking Su Ye’s formation. 16 17

Personality

Xuan Chengzi is calculating, paranoid, and intensely self-serving. He hides his cave dwelling, restricts access to his residence with protective runes, and keeps the Soul Locking Pill’s true function secret until it is useful against his victims. 44 70

His cruelty extends to anyone he considers expendable. He uses captives as pill ingredients, tortures righteous cultivators for information, drains his own disciples for cultivation, and refined his wife and child into Evil Puppets. 28 66

He is also arrogant about his preparations, taking pride in his stolen techniques and supposedly invulnerable puppets. This confidence collapses when Qin Yang removes the Soul Locking Seed and gains the strength to overwhelm him. 43 86 101

Abilities & Skills

Heavenly Yin Blood Sucking Technique

A Tianyin Sect evil art that drains blood essence, cultivation, and—in its advanced form—the soul of its targets.

• Creates a Yin-filled domain over a wide area and forcibly extracts blood qi from multiple victims. 27
• At Great Accomplishment, can drain both blood essence and souls, overwhelming even Ye Zishuang. 45
• Allows Xuan Chengzi to siphon cultivation from anyone who has taken his Soul Locking Pill. 44
• Becomes ineffective against Qin Yang after Qin removes his Soul Locking Seed with the Five Elements Refinement Technique. 86

Soul Locking Pill and Soul Locking Seed

Xuan Chengzi secretly plants Soul Locking Seeds in the Spirit Roots of captured Medicinal Seeds through his pills.

• The seed binds victims to him and lets him seize their accumulated cultivation. 44 70
• Its evil energy is attached to the target’s Spirit Root and is difficult to detect below Foundation Establishment. 70
• Xuan Chengzi considers it nearly incurable; removal requires the Five Elements Refinement Technique and a refined Spirit Soul. 86 101
• He uses the pill to ensure that escapees, including his own disciples, remain usable resources. 66

Soul-Seizing Technique

A coercive interrogation art used to break captives’ resistance.

• Xuan Chengzi employs it on Zhao Ling after she refuses to explain how the Yunqing Sect found his cave dwelling. 28
• Its use forces Zhao Ling to reveal information despite her initial defiance. 28

Spirit Seed Creation True Scripture

The incomplete half of a stolen Tianyin Sect scripture that refines spirit seeds and improves Spirit Root quality.

• Xuan Chengzi uses it to raise his Spirit Root to top-grade quality after refining more than one hundred spirit seeds. 67
• The incomplete version damages its practitioner’s Spirit Root and shortens lifespan. 101
• Its power makes it the primary object sought by Su Ye and other Tianyin Sect pursuers. 17 66

Five Elements Refinement Technique

A stolen Tianyin Sect technique capable of refining Spirit Roots and addressing Soul Locking Seeds.

• Xuan Chengzi uses it as a threat against Su Ye, claiming he can refine Su Ye’s Spirit Root. 67
• The technique is the key to removing a Soul Locking Seed by transferring it into a refined Spirit Soul. 70 101
• Qin Yang ultimately obtains and cultivates it, removing Xuan Chengzi’s control over him. 86

Evil Puppetry

Xuan Chengzi commands two Evil Puppets refined from his wife and child.

• Their bodies are strengthened through a special evil art, making them highly resistant to weapons, water, fire, and Foundation Establishment attacks. 43 73
• The puppets can kill Qi Refining Ninth Layer cultivators with a single strike and disrupt the Cloud Sun Sword Formation. 43 44
• Their control can be overridden through Evil Puppet Talismans; Qin Yang uses this weakness to turn them against Xuan Chengzi. 70 73
• Qin Yang later destroys both puppets outright after reaching the Foundation Establishment Eighth Layer. 101

Equipment / Items

• Pill refining furnace — Used in his cave dwelling to refine pills from captured Medicinal Seeds. 3 66
• Evil Puppet Talismans — Two talismans stored in his residence that can control his Evil Puppets when activated with blood. 70 71
• Spirit Seed Creation True Scripture — The stolen incomplete half of the Tianyin Sect scripture. 17 103
• Five Elements Refinement Technique — A stolen Tianyin Sect technique kept close due to its importance. 17 70

Relationships

• Qin Yang — Captured Medicinal Seed and nominal disciple; Qin becomes Xuan Chengzi’s greatest enemy, repeatedly escaping, stealing his methods, and killing him across resets. 3 17 86
• Su Ye — Fellow Tianyin Sect cultivator and pursuer seeking the scriptures Xuan Chengzi stole from their sect. 17 66
• Lu Xun — Eldest disciple; assists in capturing Medicinal Seeds and pursuing Qin Yang before Xuan Chengzi drains him for cultivation. 7 66
• Chang Er — Second disciple; assists Lu Xun and participates in the mistreatment of captives before being drained alongside him. 7 66
• Bai Feng — Subordinate who brings Medicinal Seeds into the pill refining room and helps manage the cave dwelling. 3 4
• Wife and child — Refined by Xuan Chengzi into his two Evil Puppets. 66
• Ye Zishuang — Yunqing Sect cultivator who leads the assault on his cave dwelling and defeats him after his puppets are turned against him. 43 73 74
• Tianyin Sect master — Unnamed former master whose pursuit terrifies Xuan Chengzi; may have reached the Core Formation Realm. 103

Story Role / Major Arcs

• Medicinal Seed Captivity — Operates a pill-refining den, captures Qin Yang, and uses a Water Spirit Root girl to refine Water Spirit Pills. 3
• Su Ye’s Pursuit — Is located by Su Ye after Qin Yang guides his enemy to the cave dwelling; the confrontation reveals Xuan Chengzi’s theft of Tianyin Sect techniques. 16 17
• Yunqing Sect Captives — Captures Zhao Ling, Xu Qing, and Fang Xinyun, kills Xu Qing, and uses torture to learn how the Yunqing Sect found him. 27 28
• Evil Puppet Trump Card — Uses his puppets to reverse Ye Zishuang’s initial advantage and devastate the Cloud Sun Sword Formation. 43 44
• Puppet Rebellion — Qin Yang activates the Evil Puppet Talismans from afar, turning Xuan Chengzi’s greatest weapons against him and enabling the Yunqing Sect’s victory. 73 74
• Repeated Defeats Across Resets — Xuan Chengzi is killed by the Yunqing Sect in one reset, slain by Qin after being severely injured in another, and later captured and crippled when Qin reaches Foundation Establishment Ninth Layer. 74 86 101 102
• Later Resets — Qin Yang kills Xuan Chengzi immediately after inheriting Core Formation cultivation, treating the former captor as no longer a meaningful threat. 191 201 300
