The Devil Is an Old Enemy, Not a Sweet Wife

My name is Jiang Ye. I traveled to the Xianwu Dynasty where I could achieve extraordinary things. The bad news is that at the beginning, he becomes a eunuch serving the devil, and he will die at any time when facing the moody devil. The good news is that I was not castrated and the demon king is a great beauty. When he learned that he was actually a spy sent to the devil by the largest sect in the world. I decided to put myself in danger and sneaked into the devil's palace alone to investigate, hoping to complete the task assigned by the superior as soon as possible and become a full-time disciple of the inner sect. It doesn't matter if I don't check this, it allowed me to find out the Demon Lord's fatal weakness. Your Majesty the Demon Lord, you don't want your secret to be known by Zhengdao. ... My name is Lin Qingying, the leader of the demonic path. I possess the power to reach heaven and suppress the entire era with my invincibility. A hundred years ago, in a shocking scam, nine top men conspired to seal me in this outer world, using my power to protect the fate of the dynasty. The mastermind behind all this was the demon who instigated Emperor Taizu's rebellion. He was also the old enemy who gave me inner demons. After his death, I finally saw hope of breaking through the seal, but on the day when I was possessed by the inner demon, a little eunuch who looked like him broke into the palace... ... Some years later. Jiang Ye: "If you don't want to poke at the devil's taste, why don't you call me sir?" Lin Qingying: "Be brave! You can only be my old... Enemy!"
