(No heroine!) (Dark-hearted) (Ruthless) (Darkness) (Semi-cool) (Don't criticize if you don't like it) In this dark world, the strong survive and the weak can only crawl at the bottom. All choices are for profit. A young man accidentally obtained a mysterious book and became a monk. Starting from a small village, he used all means and had no bottom line just to pursue the infinite path. (The first few chapters are slow, and then take off)
