I'm the Great Villain of the Demon Cult, but My Undercover Mission Made Me Leader of the Righteous Sect

A Wife Who’s a Righteous Dao Companion, Upright and Devoted, and Wants to Pursue the Great Dao Together with the Male Lead

The Male Lead Seems Like a Paragon of Righteousness, but He's Actually a Sneaky Villain

The Demon Sect Leader’s Son Deliberately Becomes a Righteous Sect Disciple and Lives a Lazy Life

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.

Looking for a Book Where the Male Lead Seems Righteous but Is Actually on the Demon Path

Mind-Control Novels, Like Demonic Hearts, Planting Seals, or the Star Ring Series

The protagonist controls powerful people and makes them their own.
