I Have a Crazy Book

In the dark side of the modern world, monsters are rampant - bloodthirsty shadow ghosts, twisted aberrations, and aliens disguised as humans. Ordinary people knew nothing about this until Jiang Yu picked up a crazy ancient book in his dream. The book can talk, it can laugh, it can seduce him, go and kill him. Kill any monster and you can take away its abilities, strength, speed, and regeneration. Every gift is real, and the price is equally real. The madness level soars, the sanity collapses, and the ears are filled with indescribable nonsense. He must suppress the madness before he completely loses control. Once he fails, he will become the next monster wandering in the shadows of modern cities.
