Well, I'm recently into novels in which MC transmigrates into a young master and gets a villain system, goes around killing protagonists and stealing the heroines. I've read I'm a gao fushuai villain, l am a fated villain and I became a rich,second generation villain. So if you know some novels like them, do suggest me.
The Villain of the Rebirth City, the Rich Second Generation - is about the villain counterattacking Villain: Peeking at the Diary, the Heroines Are All Set Up - is about the villain holding onto the script but heroines of male protagonist stray away thank to villain golden finger The Female President Was Tied at the Beginning, and I Became the Villain - Villain Destiny system I Started As a Novel Villain - multiple male protagonist to fight Damn It, I’m the Villain Rich Second-generation Father?

I Became the Rich Second Generation Villian We Villians Don't Want to be Stepping Stones Both are on MTL but are actually very decently readable. Both are a MC with a hero beating system
I attacked because I was afraid of death - Modern girl transmigrated into the most hated and useless character of a popular zombie TV series with a cold-hearted and manipulative system that makes her OP but controls her to make trouble. MC is super badass and cool and is doing anything she can to live and is always trying defy the bastard system. The character interaction is great with a likeable cast of characters and a well-structured storyline with underlying mystery and drama.
