It was a very ordinary notebook, with no gorgeous cover, just plain black, and the paper was also very ordinary.

White, just white, not the yellowish-white color unique to paper, nor the fragrance of raw wood, but a pale color like the paper figures in a paper shop, smelling like dampness.

Turning to the first page, there were four big characters written on it: Survival Rules.

Then, I suddenly shivered, my heart suddenly leaped to my throat. Because I saw with my own eyes that the page that originally only had "Survival Rules" written on it suddenly had a bloody line of words: "Rule Number One of Survival Rules: Do not trust anyone."

A prank? I couldn't believe words could appear out of nowhere. I looked around, the summer vacation was about to start tomorrow, classmates were all busy packing up to go home, no one paid attention to me.

My name is Bai Qi, just an ordinary college student.

Thinking about my friends around me, there was no one who could play such a joke.

I suppressed the strange feeling in my heart and threw this eerie notebook fiercely into the trash can. Regardless of whether it was some monster or demon, it had nothing to do with me.

Since I threw away that notebook, my life went on as usual. I took the train back to my hometown, feeling that the notebook must have been someone's prank.
