Some examples of ones I've loved is Regressor Instruction Manual and Dungeon Defense; FFF-Class Trashero wasn't bad either. I just don't like the harem part and really had to power through those parts. It's okay if the mc is manipulating a person to like them for a while, but I don't really want them to be there forever as a love interest. And I don't want the "evil" that's only oh I'm so cold and have no feelings so that means I'm evil hahaha like Second Life Ranker. While I like those too, it's not what I'm looking for right now. I've also read Dungeon Hunter which is tagged with Evil Protagonist, it was good, though he isn't really that evil to me. Also yes Korean ones only. I know there's a lot of Chinese ones, but I really just can't stand reading chinese stories for some reason (there's only been like one exception so far) and I don't really like the cultivation stuff and stuff. Also no Japanese ones because idk even though I like anime I've tried to read the novels for them and I just get bored.
The Lord's Coins Are Not Decreasing. Mc cares only for his friends and family. He would murder, scam, extort, torture and manipulate anyone who is against his loved ones. Also zero romance so far(200+ chapters).
*watched thread. Also, I forgot the title, but MC is named Ian Page, I think. He's a mage who went back in time.
The Regressed Demon Lord is Kind I really like this one because MC is previously a demon lord. He is basically a genius in controlling his power even when he had to restart from zero. No romance so far (last I read chapter 140something), and the adventures are fun.
Don't Know about 'Evil" but if someone dares to defy MC...He is dead... He is ruthless. He is Cold.. and he only loves one Women. He is the sky of the Demonic Cult. People of his cult worship him while other factions people call him "The Demon God". And you will see his growth and character development. Go and Check "Nano Machine" (If you haven't finished it already) And Its Korean, Chinese authors doesn't have balls to write something this amazing.(Sorry for poor English)
"Heavenly demon cant live a normal life" Action and no romance,if you want to read complete version you need to read the mtl ver
