REINCARNATOR fanfiction - transmigrated with a high Luck trait 한

Ryu Jintao reincarnated in an alternate Earth where humans mysteriously disappear all over the world. Predicting his possible fate, he lives his life while rigorously preparing himself for his inevitable second transmigration.

At the age of 20, he too gets transported to an apocalyptic survival game from a novel that he once read - 'Reincarnator'.
Equipped with his novel knowledge, Jintao stops at nothing to use this chance given to him to become a supreme existence of that world.

At one point he eventually discovers that because he lived two different lives, he's someone with two special traits, and both are very powerful.
....

Warning: In short, the MC is a villain. He's often cruel and very evil. For benefits, he might backstab his 'allies', lure them into a trap and do all kinds of amoral things, so be prepared for things like this. In certain situations he resembles Fang Yuan from Reverend Insanity, and I often reference RI as I write this story.

Second warning: Even though the MC is evil, pragmatic and scheming in his actions, he isn't a psychopathic emo kid. Don't expect him to always murder everyone he meets. He acts neutral in most situations and might even be genuinely kind if it doesn't hinder his goals or if he feels like it. He would have a lover or a few, and perhaps even a harem, since his strength allows that; though romance is really not the focus here and the girls he chooses would not be useless weaklings.

Third warning: One of MC's traits is greatly enhanced Luck (which reveals itself mainly in the form of him dropping more rare runes, skills and artifacts than others), so don't be too surprised when the MC's drops are quite lucky. But his luck trait isn't omnipotent. The main reason I chose this trait is because I want the MC to acquire many various skills, which I always find cool.
