The God of Sky & Earth - Chapter 1136:

Zero, a 35-year-old mercenary, after being betrayed by one of his teammates who told his enemy about him. He chooses suicide so that he can kill his enemy and his traitor teammate. After that, he was reincarnated into the world of magic, in the body of an 18-year-old teenager with the same name as him. However, his body does not have mana or the talent for magic. But with the help of the cultivation system, he has unrivaled power in the world and has a harem of beautiful wives.

The Return of the Heavenly Demon!I promised myself to live ordinarily for the rest of my life…….“Please be my father until I graduate.”He suddenly gained a daughter out of nowhere.

Mc is killed but he’s saved by the Villain System. He has to go to different movie worlds and complete tasks to earn villain points. There’s more to the system and the story than just going to movie worlds. The story is somewhat simple, sometimes doesn’t make sense but it’s funny and entertaining. I think it’s definitely worth the read. Just don’t expect a serious literary masterpiece or something. Obviously.

Movies: Captain America. Transformers. RE. Marvel. HP. Fast and Furious. Underworld. The Monkey King. Avengers 2. A chinese odyssey. Spiderman. X-men. And more.

Harem: Main girls from these movies. No girls left behind. There are some originals too. Mc steal girls from the og characters obvs. Basically netori. No NTR at all. And, for those who care, all girls are ‘pure’ even if they had bfs before haha
