An Immortal Body from the Start, So I’m Going to Save the World?

[Comedy + one heroine + dark fairy tale + nearly invincible protagonist + decisive and ruthless] A brooding, socially anxious man with a sharp tongue and a soft heart, no morals whatsoever, and a built-in thunderous language System transmigrates into a dark fairy-tale world thoroughly corrupted by the Seven Deadly Sins, where every fairy tale has been twisted. Through a series of mishaps, the world's will recognizes him as a fairy-tale knight. “What do you mean I’m a fairy-tale knight now, and my mission is to save this rotten fairy-tale world?” “And why do I have to take Little Red Riding Hood, a clingy yandere who’s turning into a furry, to chop down those agents of the Seven Deadly Sins?” Ge Lin: “I just want to find somewhere quiet to lie down. Who wants to be some kind of savior?” Little Red Riding Hood: “Ge... Lin, hungry!” Damn it, Red, you bottomless pit. I can’t afford to keep feeding you! From then on, getting beaten up became part of daily life. A clingy, gluttonous Little Red Riding Hood followed him around, along with a chatterbox hunter who had appeared out of nowhere and could talk from morning till night. Ge Lin stared at the sword in his hand and fell into deep thought: “Maybe this world should just be destroyed after all?”
