Furnace No. 3

My name is Chen Jiang. I worked the night shift at the crematorium because of the high salary. Don't laugh at me, the money in this business is really generous. Hand out a brochure on the first day of employment, night shift rules? The eleven items are all normal, but the ninth one is weird. It says that if your nickname is called out in the furnace, you should resign on the same day, and run as far away as possible. I thought I was an old man bluffing a newcomer. When I turned to the last page, there was a handwritten ballpoint pen: "Brother, don't be afraid, it's me." My brother disappeared in this restaurant seven years ago and is still nowhere to be seen. You said, should I run away or continue my class?
