Xu Ke

Biography

Beast Taming Sect disciple

Xu Ke begins as a kind, low-status boy in the Beast Taming Sect, once a Ningyuan beggar and now paired with a seemingly weak black bird. Song Yang mocks and pressures him, but Xu Ke steals spiritual fruit to feed the bird and refuses to surrender his companion even under threat. His first meaningful power comes through relationship rather than domination: compassion awakens the bird’s protection when the sect’s hierarchy offers him little safety. (Chapters 318–321)

After Mr. Bai devastates the sect’s beasts, Xu Ke seeks Lu Ya and struggles to reconcile people he believes to be good. He trusts Mr. Bai’s kindness, yet Lu Ya warns him about concealed violence and divided motives. Emperor Sanmo identifies the boy as part of the sect’s remaining hope. Xu Ke’s naive loyalty therefore develops into a harder responsibility: he must judge among conflicting loved ones rather than treat rank or affection as automatic proof that one side is right. (Chapters 346–348)

Mr. Bai's messenger and beast leader

Mr. Bai leaves Xu Ke a defensive carving and sends him toward Nanming Sacred Beast Mountain carrying Emperor Erli’s head. Xu Ke accepts the mission but does not translate obedience into indifference toward the beasts affected by it. He argues that those willing to remain in Xuanhuang should be allowed to do so rather than forcing the entire population into one migration. The timid disciple has become a negotiator capable of stating an independent humane position inside a far larger conflict. (Chapters 1078–1081)

Using the Beast Taming Wheel, Xu Ke coordinates more than three thousand transformed beasts and helps divide the migration between those leaving and those remaining to guard Xuanhuang. The feat establishes him as a leader while preserving the distinction between command and companionship. His decisions lay groundwork for later beast-taming, imperial, and research institutions, yet the mission’s moral shape remains recognizably his: fulfill Mr. Bai’s purpose without treating every living beast as an identical unit that must be compelled. (Chapters 1081–1083)

Millennia of guarding the evil thought

After Mr. Bai’s death, Xu Ke carries a black coffin containing separated Xuanhuang evil thought into a hidden small world. He survives for thousands of years primarily to preserve that final mission and search for a way to restore what was lost. During the long vigil he develops Heart-Linking and continues beast-wheel research, producing a lineage that does not depend entirely on the old true Beast Control Technique. The boy’s faith becomes ancient endurance, even as the burden consumes his vitality and fortune. (Chapters 1090–1094)

Xu Ke later joins the Holy Dynasty, works with Yin Shangren, and protects Mr. Bai’s skull during and after their infiltration of the Divine Treasure Museum. The loss of Xiao Hei, combined with the cost of suppressing Xuanhuang’s evil thought, leaves him white-haired, bent, and near death. He remains devoted without being wholly blind: by the end of this long guardianship, he can recognize that Mr. Bai knowingly accepted death rather than imagining that loyalty must somehow reverse every sacrifice. (Chapters 1230–1249; Chapters 1291–1302)

Renewed by Xuanhuang and the star sea

When the evil thought is purified and returned to Xuanhuang, Xu Ke receives Heavenly Favor for completing the burden he carried across millennia. His exhausted fortune recovers, his white hair turns black, and his bent elderly body returns to a steady middle-aged form. The rejuvenation is a reward and state change rather than a documented step in an ordinary realm ladder. Freed from merely preserving Mr. Bai’s last request, he redirects his loyalty toward the Holy Dynasty and the broader survival of Xuanhuang. (Chapters 1308–1311)

Xu Ke enters the Darkest Star Sea, survives residual True Immortal power, and later begins absorbing Xing Wuque’s bronze-mask inheritance with assistance. The mask offers a new route beyond his declining guardian state, but the supplied corpus does not show a completed fusion or name a resulting formal realm. His development therefore remains future-facing rather than finished: he has moved from protecting a sealed fragment of the past to carrying knowledge and inheritance that may help Li Fan and Xuanhuang endure what comes next. (Chapters 1330–1331; Chapters 1347–1351)

Appearance and personality

Xu Ke first appears as a small boy who wears the black bird in his hair, visually expressing a bond closer than a conventional master-and-beast arrangement. Millennia of guarding the coffin leave him white-haired, bent, and visibly close to death. Heavenly Favor reverses that decline in Chapter 1311: his hair turns black and his body returns to middle age. These are distinct story-period states, so an illustration should not combine the youthful disciple, ancient coffin bearer, and rejuvenated inheritor into one ordinary appearance. (Chapters 318–321; Chapter 1090; Chapter 1311)

He is gentle, loyal, protective, and initially credulous, but never merely passive. Xu Ke steals to feed a vulnerable companion, argues against forced migration, and sustains an almost impossible guardianship through patience rather than ambition. His trust in Mr. Bai matures as he encounters evidence of violence and sacrifice. By the Holy Dynasty period he remains devoted while showing independent persuasion, research discipline, and the courage to continue after the person who defined his mission can no longer return. (Chapters 318–321; Chapters 1078–1083; Chapters 1291–1302)

Abilities and cultivation

Beast companionship and Heart-Linking Technique

Xu Ke’s earliest attempt to subdue the newborn black bird by ordinary control fails; their effective bond forms through protection and trust. Over the following millennia he develops Heart-Linking from lost Beast Taming Sect research, creating cooperative links that support communication, coordination, and later imperial beast systems without relying solely on absolute domination. The origin also defines the limit: relationship cannot simply be replaced by command when a powerful beast resists. His research survives beyond his withdrawal and informs the empire’s continuing technology. (Chapters 318–321; Chapters 1078–1090)

Beast Taming Wheel research

The true Beast Taming Wheel can constrain and coordinate large groups of demonic beasts, which Xu Ke demonstrates while leading more than three thousand transformed beings. His notes and later work support replicas used by Beast Taming Sect descendants and imperial institutions. Those copies preserve only partial authority: a beast that exerts its full strength can resist them, and they remain inferior to the original wheel. By the later corpus, the technology is a foundational inheritance transmitted through institutions rather than proof that Xu Ke personally and absolutely controls every beast affected by it. (Chapters 1081–1083; Chapters 1129–1131; Chapter 1235)

Heavenly Favor and vitality restoration

Guarding the separated evil thought and losing Xiao Hei exhaust Xu Ke’s fortune, leaving his ancient body near death by the time he reenters the main conflict. When the purified thought is returned, Xuanhuang grants Heavenly Favor that replenishes fortune and visibly rejuvenates him from a bent white-haired elder to middle age. This restoration reverses attrition; it is not identified as an ordinary cultivation breakthrough or an inexhaustible healing technique he can invoke at will. Its latest confirmed effect is renewed vitality for the star-sea missions that follow. (Chapter 1090; Chapters 1308–1311)

Xing Wuque bronze-mask inheritance

After surviving residual True Immortal power in the Darkest Star Sea, Xu Ke begins fusing with the bronze-mask inheritance associated with Xing Wuque. Assistance makes the process possible, and the inheritance offers a new structural path beyond his old guardian condition. The corpus ends before the fusion’s completed mechanics, permanent appearance, costs, or formal rank are established. It should therefore be described as an ongoing acquisition rather than a finished new realm or a settled replacement for his Heart-Linking and beast-research legacy. (Chapters 1330–1331; Chapters 1349–1351)

Power progression

Relationships

• Xiao Hei is Xu Ke’s black-bird companion and the emotional basis of his approach to beasts. Their bond succeeds through trust where straightforward subjugation initially fails.
• Mr. Bai is Xu Ke’s teacher, benefactor, and the central object of his millennia-long devotion. Xu Ke protects his mission and remains, while gradually accepting that Mr. Bai chose sacrifice knowingly.
• Lu Ya challenges Xu Ke’s simple faith in Mr. Bai and forces him to confront the possibility that affection and goodness can coexist with concealed violence.
• Song Yang is an early persecutor whose threats reveal Xu Ke’s willingness to endanger himself for his weaker companion.
• Yin Shangren becomes a fellow researcher and confidant during the Holy Dynasty period, including the Divine Treasure Museum operation.
• Li Fan becomes a later strategic ally in efforts to save and elevate Xuanhuang; Xu Ke’s loyalty broadens from one dead teacher’s request into this collective project.

Items

• Mr. Bai’s defensive wooden carving is gifted to Xu Ke and can perfectly rebound even a full Dao Integration strike for a limited number of uses.
• A red string left by Mr. Bai serves as another defense and is later preserved within the empire rather than continuously carried by Xu Ke.
• The black coffin is carried and guarded by Xu Ke because it seals separated Xuanhuang evil thought; the dangerous contents are a charge, not property he claims as his own.
• Mr. Bai’s skull is protected and temporarily carried by Xu Ke after the Divine Treasure Museum infiltration.
• Beast Taming Wheel replicas derive from Xu Ke’s research and transmission, but later sect descendants and imperial institutions also operate them.
• The Black Bird Feather is a relic of Xiao Hei’s lineage associated with Xu Ke’s historical identity; its later use by others means it should not be presented as permanently remaining in his personal custody.
• The Medicine King True Cauldron enters the wider allied operations connected to Xu Ke’s later storyline, but it is the Medicine King Sect’s foundational vessel rather than Xu Ke’s personal cauldron.
