The author also has another book (I will update Chapter 10 on May 1st tomorrow)
My name is Chen Du, and I work as a body transporter at a funeral home, earning a monthly salary of 18,000. Master Qin, who took care of me, only taught me four rules of vigil: don't turn off the lights at night, don't answer silent calls, don't look at the surveillance camera at three in the morning, and don't open the door when you hear any noise. Relying on these four rules, I stayed safe for two years. Until that day, Master Qin asked me to open the seventh cabinet in the third row of the morgue - inside lay a body that looked exactly like me, with a silver ring engraved with my name on his hand, and a copper coin that did not belong to this era in his mouth. From that day on, I learned that there were more than four real rules for a vigil, and that deep underground in the funeral home, there was a secret room with a locked sarcophagus. When the full moon night comes, I must perform that ritual alone - either you get rid of it, or you become the next one. (In Chapter 2, the position of Chapter 10 was posted incorrectly. Sorry guys)
