[No System + An Unconventional Demon Lord + A Scheming Protagonist + Light Comedy]
Li Lin transmigrated as the Holy Son of the Hunyuan Dao Sect. Correction: the former Holy Son. From the start, he was sent to the Hehuan Sect as a live-in son-in-law, becoming an undercover agent planted there by his sect.
But after the former holy son of the immortal sect entered the Hehuan Sect, ranked sixth among the demonic sects, the entire demonic world began to turn upside down.
Hehuan Sect Master: "What cauldron? That's my precious darling! He stands shoulder to shoulder with me, the sect master!"
Heavenly Demon Sect's demonic seed: "Big Brother can torment me a thousand times, but I still love him as if it's the first time. In life, I'm Big Brother's; in death, I'm his ghost... Big Brother, I recited it just like you asked. Please stop messing with me now!"
Ancestor of the Moyin Valley: "You say I'm sinister and treacherous? I refuse to accept that! Am I as sinister as that kid? He... he has no demonic honor! He ambushed me! You have to avenge me!"
First Heavenly King of the Blood Demon Heaven: "Would you believe it? He replaced all the blood in my vault with grape wine! I haven't tasted blood in a whole year! Look at my adorable little 'darlings.' Every last one of them has turned into a drunk!"
Three years later, the immortal sects joined forces to launch a campaign against the demonic path, only to find that the one sitting on the Demon Lord's throne was none other than Li Lin, the immortal sects' castoff!
Li Lin spread his arms wide. "Fellow Daoists, you've finally seen the light! Welcome to abandon immortality and join the demonic path! Become part of building a civilized demonic world!"
Love is always the same across thousands of rivers and mountains, can you vote for me? I beg you for reminders and votes!
