Background / History

Lu Caiwei initially showed considerable cultivation promise, reaching the First Realm quickly before an unexplained illness erased her progress. After spending several years unable to restore her cultivation, she was expelled from her Lineage. Her condition improved after she left and joined the Heavenly Prison 5.

Lu Qingshan personally recruited her years before the prison disaster. Zhao Changhe had heard that she previously belonged to a powerful Lineage in another country, though this information is presented as hearsay 15.

She later served alongside Xu Fang, Lin Qingqing, and Bai Changzai in Grade B, Squad Five, which repeatedly earned outstanding merits. Following the prison catastrophe, the squad was demoted to Grade C; without Caiwei, its remaining members no longer qualified for Grade B status 22.

Appearance

• White clothing: Wears white robes and a long dress; its hem becomes bloodstained during the eighth-level ordeal 4 6.
• Youthful appearance: Looks approximately fifteen or sixteen to Ye Wuyou 5.
• Skin: Described as flawless and jade-like 7.
• Voice: Normally clear and sweet, but interrupted by a pronounced stutter 4 5.
• Combat presence: Her relaxed demeanor gives way to sharp, oppressive pressure when she draws her sword 5 6.

Personality

Caiwei is withdrawn and hesitant in ordinary conversation. Her stutter makes lengthy explanations difficult, so she sometimes writes on the floor with her sword tip instead. In combat, her speech becomes clear and her actions cold and decisive 4 5.

She is protective and exceptionally stubborn under pressure. While trapped with Ye Wuyou, she shares supplies, maintains watch for three days and nights, and continues fighting despite mounting exhaustion. She resorts to self-inflicted pain to preserve her awareness against the prison’s mental erosion 6 7 8.

Her letter after their rescue reveals a warmer, more expressive side. She thanks Ye Wuyou, acknowledges that she owes him a favor, and promises to protect him from her furious master 16.

Abilities & Skills

Swordsmanship

Caiwei specializes in sword cultivation and can rapidly dispatch opponents who remain dangerous to an untrained Ye Wuyou 4 6 23.

• Kills an anomaly-controlled colleague with a single strike 4 5.
• Defeats several withered former jailers in sixteen breaths, despite their continued use of martial skills and cultivation techniques 6.
• Cannot directly see the anomalies, instead relying on instinct and careful sensing 5 11.

Sword Rises with Wind and Thunder

Her signature demonstrated technique produces brilliant sword light and a powerful offensive burst. Xia Anmeng has personally guided her use of it 6 9.

• Uses the technique against the animated corpses on the eighth level 6.
• Breaks the spatial loop blocking the escape route after her soul is stabilized 10 11.
• Requires a particular cultivation method and precise qi circulation; mistakes can injure the user 9.
• Zhao Changhe describes it as a barrier-breaking move that forcibly drives the energy channels and concentrates power into one point 17.
• Ye Wuyou reproduces it through the Formless Heart Sutra after observing her, rather than receiving formal instruction from her 8 17.

Resistance to Mental Erosion

Her Third Realm cultivation and Xia Anmeng’s protection allow her to resist the eighth level’s influence temporarily, but do not make her immune 6.

• Uses pain from cuts and stab wounds to remain lucid 6 7.
• Receives temporary protection from soul power Xia Anmeng leaves in her body 8.
• Eventually suffers near-total erosion of her own soul and requires Ye Wuyou’s intervention to survive 10.

Aptitude Assessment

• Examines Ye Wuyou’s cultivation aptitude and judges it “all right,” only slightly worse than her own 5.

Equipment / Weapons / Items

• Sword — Her primary weapon, also used to write explanations on the floor. Ye Wuyou later considers it superior to the sword he selects at Zhao Changhe’s residence 5 17.
• Spirit Absorption Ring — Identified by Ye Wuyou’s narrator as housing a Sixth Realm woman’s remnant soul, later revealed as Xia Anmeng 5 7.
• Storage ring — Supplies water and rations while she and Ye Wuyou are trapped 6.

Relationships

• Ye Wuyou — Fellow jailer and mutual rescuer. She initially interrogates him, then protects and provisions him. He saves her deteriorating soul by placing part of his own soul within her; afterward, she leaves gifts and promises him protection 4 6 10 16.
• Xia Anmeng — Master and resident remnant soul. Xia guides her swordsmanship and protects her from erosion. Possessing Caiwei can only slightly increase her cultivation, consumes Xia’s soul power, and does not allow Xia to directly use her own techniques through her disciple 7 8 9.
• Lu Qingshan — Prison Warden and the official who personally recruited her. He retrieves her alive from the eighth level. Zhao Changhe speculates about a family connection because they share a surname, but no kinship is confirmed 15.
• Xu Fang, Lin Qingqing, and Bai Changzai — Former Squad Five teammates. The squad’s demotion follows the prison disaster and the loss of Caiwei from its active roster 22.

Story Role / Major Arcs

Heavenly Prison Disaster

• Initial encounter: Finds Ye Wuyou apparently returned from death and questions him at swordpoint. She accepts his fabricated explanation, then kills a controlled colleague behind him 4 5.
• Eighth-level confinement: Explains the prison’s restrictions and waits for the Fifth Realm warden’s return. She guards Ye Wuyou while the uncanny steadily erodes her mind 5 6.
• Collapse: After days of watch and fighting, she loses control despite using pain to remain lucid. Xia Anmeng temporarily takes over her body, then moves into Ye Wuyou while leaving protective soul power behind 7 8.
• Soul rescue: Ye Wuyou performs the Soul-Controlling Scripture—Life-and-Death Brand, restoring her clarity. He discovers that withdrawing his soul would leave her little more than a living corpse 10.
• Escape: Caiwei breaks the looping passage. Ye Wuyou later carries her into a cell that shields them from the aberrations outside 11 13.
• Recovery: Although her life lamp goes out, Lu Qingshan finds her unconscious but alive and removes her from the prison. She can get out of bed and walk the next day 9 15 17.

Aftermath

• Visits Ye Wuyou while he is unconscious, leaving two Sixth Realm cultivation manuals, medicinal herbs, and a letter before departing on a mission 16.
• Her letter warns that Xia Anmeng wants to kill him but is currently too weak; Caiwei promises to protect him 16.
• Her soul damage helps motivate Ye Wuyou to choose a fox-capture mission rewarded with jade soul flowers, which nourish injured souls 21.
