I.. Am God? - Chapter 41 Mysteriously Reincarnated To A Primitive Earth

Hao Ren (literally means “good man”), as his Chinese name suggested, is a good man, and his ideal was to live a restful, comfortable life as a landlord. At least that was his plan before a couple of abnormal creatures rented his house.

“I think… my boyfriend is trying to kill me,” Lin Sanjiu muttered.

As she thought about that rich, handsome, and gentle boyfriend of hers, she could not help but tremble all over.

At the present, someone close to her had personally raised the curtains to an apocalyptic hell, and slowly, it was creeping up to her.

What if earth devolved into a apocalyptic hellhole? What if you found out you not only have to survive just one apocalyptic event but have to struggle through multiple worlds with different end-world scenarios? And you get to meet more superpowered crazies than you can imagine!

Presenting the worst nightmare that your weird doomsday prepper neighbour with a bunker full of canned beans could have, Doomsday Wonderland is a novel filled with subverted tropes, non-OP characters and a female friendly label which offends all politically correct fanatics.

As ‘lucky’ humans evolved to posthumans with abilities to adapt to the New World or mutate into disgusting duoluozhongs to survive, follow Lin Sanjiu as she struggle through the multiple challenges to just live one more day… and make sense of this New World that will no longer be the same.

- Description from novelbuddy

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
