I Went Undercover in the Demon Sect for Thirty Years, and I Fell to the Dark Side

The Male Lead Falls to the Demonic Path, and Only the Female Lead Can Get Through to Him

The male lead falls into demonic madness, and no one but the female lead can control him. A spectacular case of double standards.

“I Was an Exiled Immortal, but Fell to the Demonic Path for All Living Beings.” Looking for Stories Where the Male Lead Turns to the Demonic Path After Being Hurt

The Male Lead Joins a Demonic Sect and Cultivates Its Techniques

The protagonist is the current leader of a demonic sect, secretly correcting orthodox cultivation techniques every day, and the sect's bigwigs still haven't noticed! Are you that good at hiding it, or are all the bigwigs undercover agents? I don't need the protagonist to kill people to cultivate. I just want the male lead to practice the sect's own demonic techniques. No stories where he takes in a few people and every single one turns out to be a prodigy.
