I'm an Undercover Agent of the Devil's Sect, and the Female Devil Shows Me Too Much Favor.

Xiao Luo was reborn, blessed by Pangu, with the same fortune and longevity as heaven, enjoying endless opportunities in heaven, endless marriages, changing his destiny from a little cultivator against heaven, and having endless fun fighting against heaven and earth! Zhengdao asked me to work undercover in the demon sect, but instead I was adopted as the son-in-law by the female devil. I am actually the destined villain? The male and female protagonists are both ants, but my eldest wife is the real meat and potatoes! She said: "When my power over the world is over, I will kill everyone in the world who betrayed you!"
