Introduction: Rule 3 of the night shift at the funeral home: If you hear someone calling your name in the morgue, don't answer.
On Yu Xu's first night on the job, all the cabinets were calling his name.
Others are trying to escape from a desperate situation by bumping into ghosts. Yu Xu said that bumping into ghosts is like touching a corpse to become stronger - he found that he could find out the rule entries from the corpse and turn the ghost's abilities into his own. So when the S-class monster came out of the cabinet, he took out the opponent's [Immortal] entry with his backhand, held a flashlight and shined it at it, and smiled.
"Come on, let's talk about the rules."
While others lived by the rules and strange stories, he grew up obscenely in the funeral parlor. Forbidden land-level ghosts knelt down and begged to be admitted, and the incarnation of the rules personally went out to hand over the offer - until one day, all the weird things heard the intercom of the crazy night shifter ringing: "Brother Yu, the underworld branch has just been established tonight, are you here to cut the ribbon?"
