Big Shot Ma Mian, Don't Die

Niutou went off to enjoy himself, leaving the big shot Mamian green with envy.

To find himself a partner, he secretly slipped into a book world to cultivate immortality, planning to trick some sweet, naive girl into coming home with him as his wife.

Who knew that one day, his sweet, naive girl would turn into a yandere? The big shot Mamian was scared out of his wits.

The human world is terrifying. He wants to kill the mortal world [redacted] and go back to the underworld.

The sweet beauty with a round face pointed a knife at him, her voice soft but vicious: "If you do that, I'll crush your entire soul!"
