With his own strength, he cleans up the villains and slays evil gods, but many villains still flee to Jiuzhou. At the same time, his physical body in the present world has been sleeping for ten years as the illegitimate son of the Kai family, the number one family in the sea city. When Kai Sterling awakens, he discovers that his first love, Seraphina "Sera" Vance, who doesn't know his true identity, has taken care of him for ten years and used this name to become a sentimental internet celebrity. But for some reason, Seraphina "Sera" Vance seems to be entangled by Leo Vance, the top brother on the list, who not only cheated on him, but also wants to harm him at the instigation of Leo Vance. Kai Sterling has returned this time, and with one move, he solved the villain that the Dragon Claw Gang had been hunting for many days, but he intentionally takes revenge on Leo Vance slowly, just to find out why Seraphina "Sera" Vance betrayed him.
