Xu Kai

Biodata

Power Progression

Background

Before entering the game, Xu Kai was an ordinary university student on Blue Star. His last remembered experience was waiting hours to buy a power bank advertised as granting school credits; he could not remember how he died 1 2.

He awoke bound in an abandoned hospital room, where Weird Duke described him as a resurrected human material meant to serve Weirds. Repeated deaths during authentication revealed his apparent Death Rewind talent. On his twenty-third rewind, Xu Kai realized Weird Duke could not see his game data and falsely claimed his talent was Passive Warning 1 2.

Weird Duke sold him to Stone Statue Weird, who assigned him a role in the Crematorium Instance. The trade convinced Xu Kai that he needed to become strong enough to escape others’ control 2 3.

Appearance

Xu Kai is a young man whose face retained its appearance from his previous life after he entered the Crematorium Instance 3.

• As an Evil, he ordinarily perceived the world in black and white, with Weird Energy visible in red 3.
• At Red Shirt Hospital, advancing alienation gave him red eyes and beastlike physical changes. Shortly before his promotion, his pupils were entirely red 32 36 49.

Personality

Xu Kai remains observant under threat and uses deception to conceal what he knows. He exploits opponents’ assumptions and game rules, including by claiming weaker talents and feigning helplessness 1 2 7 16.

Repeated deaths taught him to suppress anger when it interfered with survival, though their pain and memories still accumulated. He is willing to kill or abandon others to survive, but retains his own sense of right and wrong: Wang Bangfang’s suffering angered him, and he later helped Kana escape the hospital while refusing to sacrifice his life for her 5 13 18 41 49.

Abilities & Skills

Death Rewind

Xu Kai’s apparent talent returns him to an earlier point after death while preserving memories of failed attempts. The game had not authenticated the talent by his promotion 1 50.

• He used repeated attempts to memorize the lethal bends on the crematorium road and later to learn Nurse Lin’s attacks 5 47 48.
• Erasure by the game could also trigger a rewind 21 25.
• The memories of pain accumulate; by his 150th Save-Load, their physical and mental burden had become severe 5 48.

Weird Energy Manipulation

Xu Kai can force Weird Energy out of his body and shape or direct it. Releasing it is painful, but his experience of repeated deaths lets him tolerate considerable quantities 7 8.

• Forms ropes, webs, blades and spikes; he can also sharpen objects or restrain opponents 7 8 45.
• Strengthens his body and moves himself by pulling with energy 27 30.
• Uses webs or extended energy to detect movement and sense his surroundings, though his sensing was not always precise 41 45.
• In his early tests, ordinary use did not consume his 110-point reserve unless he took damage 8.

Fire of the Gaze

After the Flame and High-Altitude Ghostly Aura Fragments fused, Xu Kai could create fire by expending Weird Energy 13.

• Before promotion, each use cost 10 Weird Qi 13.
• As a Low-Tier Weird, anything he stared at for more than one second would ignite. He could control the flames, whose intensity scaled with Weird Energy Strength 50.

High-Altitude Fall

Xu Kai gained a falling ability from the fused fragments 13.

• Before promotion, it cost 10 Weird Qi and was limited to suitable high places, such as cliffs or balconies 13.
• After promotion, he could force objects at high altitudes to fall; damage was calculated from Weird Energy Strength multiplied by height 50.

Regeneration and Durability

As an Evil, Xu Kai could survive severe injuries and use Weird Energy to pull damaged tissue together. His heart was the source of his Weird Energy, making it a vital point 34 36.

• He survived being cut in half and used Weird Energy to stitch his body back together 48.
• Hospital alienation could increase his strength and help repair injuries, but it also distorted his perception and risked turning him into a monster 31 40 41.

Equipment & Items

• Ghost Entry Ticket — Synthesized from three portions of Source Weird Qi; granted entry to the exclusive Battle of All Evils instance 23 24.
• Temporary Ghost Advancement Card — A single-use card that could raise his power to ghost level for one hour, followed by ten minutes of weakness 24.
• Hospital High-Level Access Certificate — Obtained as a Chief’s Gift after killing the doctor; Xu Kai kept it wrapped and at a distance after a previous encounter with its overwhelming information killed him 42 45.
• Discharge Certificate — Had room for three names. Xu Kai wrote his own and Kana’s names on it, allowing her to leave the hospital 49.

Relationships

• Weird Duke — His original owner, whom Xu Kai deceived about his talent. Weird Duke later lent Stone Statue Weird three Evils to target him 1 2 11.
• Stone Statue Weird — Xu Kai’s former dungeon master and recurring enemy, responsible for many of his deaths in the Crematorium Instance 2 6 11.
• Wang Hua — A player whose gaze could immobilize him. After repeated hostile encounters, Xu Kai manipulated her into entering the Cremation Workshop alone, where Stone Statue Weird killed her 5 11.
• Wang Bangfang — The victim whose memories Xu Kai encountered through the Ghostly Aura Fragments. Xu Kai learned that Zhang Dekai had sent him to be cremated while still alive 13.
• Short-haired woman and JK — Players Xu Kai helped through the second Crematorium Instance. The woman eventually recognized that he was an Evil 18 20 23.
• Kana — A hospital nurse who helped Xu Kai navigate the instance. He rewound after a failed escape attempt and ultimately put her name on the Discharge Certificate 31 37 46 49.
• Nurse Lin — A dangerous competitor at Red Shirt Hospital. Xu Kai used repeated Save-Loads to learn her attacks and ultimately defeat her 44 47 48.

Story Role & Major Arcs

Crematorium Instance

Assigned as a funeral car driver, Xu Kai repeatedly died on the road before learning to navigate its deadly bends. He then discovered that Stone Statue Weird intended to sacrifice him as well as the player Wang Hua 5 6 10.

Xu Kai exploited the wording of a workshop task, persuading Wang Hua to close the door while he remained outside. After the instance, he refused Stone Statue Weird’s invitation to return to the City 11.

Maple Town and Second Crematorium Instance

While staying in the instance world, Xu Kai confronted Zhang Dekai, learned the truth of Wang Bangfang’s death, and fused the two Ghostly Aura Fragments 13.

On returning to the crematorium as a driver, he fought off Evils sent against him and helped JK and the short-haired woman survive. After the players escaped, he combined three portions of Source Weird Qi into a ticket for Battle of All Evils 18 20 23.

Battle of All Evils

At Red Shirt Hospital, Xu Kai navigated lethal rules, rival competitors and escalating alienation. He used repeated deaths to learn the hospital’s traps, fought Nurse Lin, and resisted a monster that attempted to take his identity. On his 200th Save-Load, he gave it the dead doctor’s number, causing the game to eliminate it 25 36 44 48.

As the only remaining participant, Xu Kai obtained the Discharge Certificate and helped Kana leave. He then reached the designated location and completed his promotion to Low-Tier Weird 49 50.
