Appearance

A burly, bearded middle-aged man with a somewhat handsome face and a stern, proud bearing. He wears the Golden Robes of the Demon Slaying Division and carries a Golden Robe token at his waist. After the Yunzhou crisis, fatigue and white hairs become visible at his temples, though he remains straight-backed. 65 131

• Nearly two meters tall. 65
• Full beard. 65
• Hawk-like, sharp gaze when assessing threats. 95 97
• Often carries a large bow, a sword, and bones used with his Spiritual Power. 66 134

Personality

Zhang Hengyi is a disciplined commander who treats demon-slaying as a grave responsibility. He calculates enemy strength, preserves his own stamina for decisive confrontations, and prepares evacuation measures even while leading dangerous beheading operations. 68 69 73

He possesses a deep conviction in humanity's resistance against demons. Even after being brutally wounded by Master Chen the Flood Dragon, he rejects the demon's claim that humans are inherently weak and continues attacking with his own bones and body. 76

Though initially wary of Lu Jun's defiance of the Empty Realm, Zhang Hengyi ultimately chooses to support him. His trust is rooted in Fang Jinyi's judgment and in Lu Jun's demonstrated commitment to slaying demons. 69 83 Later, he remains reluctant to believe that Lu Jun has fallen to the demonic path, even when evidence and official pressure force the Division to issue a wanted notice. 131 136

Abilities & Skills

Bone-Tracing Spiritual Power

Zhang Hengyi's Spiritual Power allows him to use bones as a core for manifested humanoid phantoms. In his desperate battle with Master Chen the Flood Dragon, he uses one of his own ribs to create a duplicate that joins his assault. 76

• Tracing Bones to Reveal the Past — His final attack against Master Chen; a rib transforms into a human-shaped phantom capable of breaking the ice imprisoning him and fighting beside him. 76
• Bone Tracing Immortal — Can use residual bones and lingering aura to restore a demon's former strength in a manifested sword-wielding phantom. 134
• The technique inflicts severe bodily harm when he uses his own bones as its foundation. 76

Demon Skeleton Combat

Zhang Hengyi can draw upon the strength of two Demon King skeletons in battle. He uses them against Master Chen the Flood Dragon, though the Jiao ultimately overwhelms him. 75

Command and Tactical Planning

As a Golden Robe Envoy, Zhang Hengyi directs Demon Slayer forces during large-scale operations.

• Divides the Qinghe operation into a mountain assault team and a county defense-and-evacuation team. 69
• Plans a decapitation strike on Evil Flood Dragon Ravine while ordering allies to conserve his strength for the Jiao. 73
• Uses a Golden Holder Token's hidden tracking mark to expose the Puppet Corpse Dock's attempt to seize it. 95
• Anticipates that the assault on the Yunzhou Demon Slaying Division is a deliberate trap rather than a simple frontal attack. 98 99

Equipment

• Golden Holder Token — Symbol of Golden Robe authority; its stored vital blood and hidden tracking function become central to the conflict with Puppet Corpse Dock. 68 95
• Large bow — Prepared for ranged attacks against airborne enemies. 66
• Sword — Used in direct combat and while commanding defensive actions. 102
• Bones for Spiritual Power — Includes a sword-like bone used to manifest a demon sword-ghost phantom. 134

Relationships

• Lu Jun — Fellow Demon Slayer and trusted combatant. Zhang Hengyi recognizes Fang Jinyi's Golden Holder Token, entrusts civilian safety to Lu Jun, and later supports Lu Jun's decision to kill an Empty Realm envoy. 69 83
• Fang Jinyi — His mentor. Fang Jinyi once entrusted Zhang Hengyi with a Golden Holder Token and instructed him to pass it to the Law Seeker with the greatest potential and conviction to eradicate demons. 69
• Mo Lou — Allied Demon Slayer who assists Zhang Hengyi in the Qinghe operation and Yunzhou's defense. 69 73 98
• Mo Jinyi — Yunzhou's local Demon Slaying Division leader. Zhang Hengyi consults him on defenses and helps purge corpse fiend energy from his body. 97 95
• Li Tuo — Subordinate and messenger during the Yunzhou crisis. Zhang Hengyi orders him to abandon outer positions and retreat to the Division when enemy forces overwhelm them. 97
• Master Chen the Flood Dragon — Enemy Jiao Demon King who nearly kills Zhang Hengyi during the decapitation operation. 75 76
• Cao Yang — Fellow Golden Robe with a more aggressive approach toward Lu Jun. Zhang Hengyi later orders him not to pursue Lu Jun beyond Yunzhou City. 134 135
• Yu Qinglian — Demon Slaying Division Commander. Zhang Hengyi reports the Yunzhou conflict and later gives his assessment that the black-robed suspect is not Lu Jun. 106 136

Story Role / Major Arcs

Qinghe Flood Dragon Operation

Zhang Hengyi arrives from Shuo Province with hundreds of reinforcements and assumes command of the operation against Master Chen the Flood Dragon. 65 67 He accepts Lu Jun's suspicion of Lin Qi and expels her from the planning meeting. 68 69

He leads Team One into Hidden Dragon Mountain for a decapitation strike, assigning the remaining forces to delay Demon Generals and preserve his True Qi for the final confrontation. 69 73 Master Chen defeats and grievously wounds him, but Zhang Hengyi continues fighting through his Bone-Tracing Spiritual Power until Lu Jun arrives to save him. 75 76

Empty Realm Incident

After the Flood Dragon's defeat, Zhang Hengyi initially invokes Dagan's prohibition against killing Empty Realm envoys. 81 82 He reconsiders after recognizing that the Empty Realm repeatedly obstructs humanity's efforts to eradicate demons, then explicitly tells Lu Jun to kill the envoy and accepts responsibility. 83

Yunzhou Crisis

Zhang Hengyi returns to Yunzhou amid the Puppet Corpse Dock's betrayal and the capture of local Demon Slayer forces. 86 He confronts the Dock Master, feigns agreement to trade his Golden Holder Token, and activates its tracking mark to launch a counterattack. 94 95

When corrupted Law Seeker families assault the Demon Suppressing Tower, he orders a strategic retreat, activates the Ninefold Mountain and River Grand Formation, and directs the Division's defense. 97 He identifies signs that the enemy is deliberately gathering the Division into a larger trap. 98 99

Lu Jun Investigation

Following Lu Jun's disappearance and the attacks attributed to wind-element divine abilities, Zhang Hengyi supports a wanted notice intended to bring Lu Jun back for clarification rather than execution. He remains unconvinced of Lu Jun's guilt. 131

When Lu Jun later confronts Demon Slaying Division Golden Robes, Zhang Hengyi holds back while Cao Yang attacks. He does not pursue Lu Jun beyond Yunzhou City and concludes that the weaker black-robed suspect could not have been Lu Jun. 134 135 136
