Even though Gu Yunxi was created from the accumulation of the resentment of souls, there was not a bit of ruthlessness nor cruelty in his nature, only a desire to cultivate. Just as he achieved his human form, he was sent to reincarnate. Under the control of Heaven, he experienced life after life of suffering, dying a terrible death every single time. After thousands of reincarnations, thousands of terrible deaths, he finally accumulated enough power to escape from the Laws of Heaven. He swore to get revenge on this blind Heaven’s Law that’s unable to differentiate good from evil.

So what if it’s the Heavens? He will stir up the rights and wrong, the good and evil!

You want me to accept this life and die, but I just won’t! I want to live, to rebel against the heavens, to reverse this joke of a destiny!

Son of a bitch! I just finished this godawful fantasy novel, and now I'm knee-deep in it – as David, the disgraced son of the Solarian Empire's top general! Talk about some twisted cosmic joke. But hold on a damn minute... maybe this isn't all bad. Armed with the knowledge of that trashy plot, I can become the ultimate shadow player, an overlord perhaps. Screw the damsel-in-distress harem too – it's time to pull the strings and become the real power behind the throne. This isekai might be a steaming pile, but I'm rewriting the ending with a little more... Debauchery (wink wink).
