Living in a Big City, the Book Said I Died Again

Do not run away at the end of the world and stay in a big city full of weird things [Rule: If I can't find you, then you can't find me; if you see me, then I also see you; if I can't see you, then you can't see me] On the day the disaster struck, I was still working in the largest city in the east. Overnight, the entire city was completely shrouded in weirdness, making it impossible to get out. I was living in a small rental house and accidentally picked up a shabby notebook with no cover and unknown origin. On the back of the title page, there is a line of dazzling bloody writing, which seems to be announcing my fate: I am Shen Ci. When I see this, I am already dead. Please look back. There is no author or origin in the book, only cold and cold transcripts of top-secret secrets. I stared at the words, feeling cold all over. The book says, I am dead. But I'm obviously still alive. Or should I say... Have I died many times since I picked up this book?
