I Simulated Ten Billion Years and Can Inherit Every Reward

[Simulation + Modern Urban High Martial Arts + Showing Off and Face-Slapping + No Female Lead + Ruthless and Decisive]

The protagonist, Xu Tian, transmigrates to a high martial arts world by accident, only to discover that his martial arts talent is mediocre and that he is about to be humiliated and dumped by Liu Ruyan.

As a post-00s transmigrator from the twenty-first century, he can't put up with it. He goes straight for a hard slap in the face, making enemies of Liu Ruyan and the others. By chance, he awakens the Otherworld Simulator.
