Super Villain System

What exactly are villains? Do they want to dominate the world their entire lives, or do they want everyone to be their enemies and to stir up trouble? After being reborn, Su Xin receives help from the "system". From it, he can obtain the skills and martial arts of all the villains from the previous martial arts world. "My name is Su Xin, which means faith in Chinese." Source: Webcomics
