Looking for a story where the MC is a disciple from a righteous sect a senior brother or some sort, but found out that he was betrayed and most of the people he knew in the sect are only using him for heir selfish goals. He left the sect and had a relationship with the daughter of a demonic sect's master. Most of the people in the demonic sect weren't really evil, they just don't like following rules. In the end he became the master of the demonic sect, and exposed all the schemes of the righteous sect. yeah, that as far as I could remember. I don't even remember if this was an arc from a quick transmigration novel or a full novel. does anyone remember a plot like this? I really want to read it again.
He eventually became the master of the Demonic Sect, exposing all of the Righteous Sect's schemes. Hmm...maybe try this :"I Started The Game Shocked The Empress"
Perhaps Sick Beauty But I don't remember him having a relationship with the daughter of the demonic sect, so perhaps not. This one is BL.
