// Power up // weak to strong //

After losing everything to the Vampires, Segun meets the Vampire hunter Silvester to become a hunter for himself. "Welcome to the world of the psychedelic moon".
I would say this is a bit of a hard read so take it slow.

Betrayed by those around him he is killed, only to be reincarnated. So he starts over with a family and no longer alone. And when he gets old enough, he starts his pact to get revenge on those who done him wrong in the past by overwhelming power.
Side note: this is usually a pretty light hearted webtoon, and it's funny. The MC builds good relationships with those around him but I doubt anyone would like the people who killed them in the past.

boy named Shi Shan along with his little sister were offered as sacrifice to a demon that has been haunting their village. They were rescued by a martial artist who exorcise demons. He took the siblings in as his disciples and taught them the art of cultivation and about the demons that dwell in this world.
Starts slow, but is very good.

Novel to comic, I do recommend reading it.
