Late at night, the funeral home posted a vigil assignment, with a daily salary of five figures, and only hired young people. On the night he joined the company, Yun Ci encountered three fatal rules: no turning back after midnight, eyes closed when the portrait smiles, and the knocking sound of the morgue... One knock is considered a call for help, three knocks are fatal. Everyone thought he was a rookie who was here to die, until he crossed out the first rule with a red pen - he could tamper with any rule. When the evil spirit knocked out the third time with a ferocious smile, Yun Ci took up his pen and added a sentence at the end of the rule: knock a hundred times and you will be saved immediately. That night, the morgue worked harder than the pile driver.
