Li Ke Lin (also Li Colin), a Chinese office worker, woke up to find himself suddenly no longer Li Ke Lin but instead Colin Lee, son of multi-billionaire in America. Having taken over the body of Colin Lee and carefully imitated his manners and bearings, his next goal is to inherit his father’s wealth. However, when his father lists the condition of marrying a woman who feels repulsed by Colin Lee’s (not Li Colin’s) dalliances, and whose very nature is the complete opposite of Colin Lee (not Li Colin), what must he do to gain her affection?!

What do you do when you're a loser who is suddenly called the saviour of the world!? You use it as an opportunity to take charge of your own life while picking up cute girls along the way!

Han Luo is just that kind of person, a perverted loser who is suddenly told he is the saviour of the world.

“what do you mean I'm the only one!? cant you see I'm a loser!?”

“If you want to kill me then you are going to have to work for it! My life isn't that cheap!”

Join Han Luo on his journey through the post-apocalypse!

[P.S. This is tagged Overpowered because I always wanted to create someone unbelievably strong. So Han is going to become one of the damn strongest people on this entire site - not just this story. But a good story needs growth, not just a quick power dump, so he'll be a bit pitiful at first, around chapters 1-15. So please bear with me till he gets back from his first time skip. After then, you'll be in for the ride of your lives]

The most vulnerable time in a tennis game is when you are leading; even if there is a match point, the game is still possible.

Football is round, tennis is also round.
