Loser's Strongest Emperor Resets His Life

Chen Xu was the most powerful god-emperor in heaven and earth, but his body was disintegrated by the combined attack of four other god-emperors. His soul could only escape by reincarnating into the body of a weak young master. As a once nearly invincible being, he wasn't about to put up with being bullied in this life. Chen Xu swore he will regain his powers and have his bloody revenge, but he had to start his immortal cultivation with an incomplete technique manual. Little did he realize, that this incomplete manual is about to make his road to immortality a lot more interesting.
