If I Want to Live, I Will Kill Everyone in the World!

[Slowly turning dark—no system—no heroine—decisive killing in the later stage—gradually becoming less of a human being] Su Yan traveled to a remote mountain village in a world of immortality since he was a child. He was bullied since he was a child and watched his mother die tragically. By chance, he obtained the magic skills. In order to survive in this world, he practiced the magic skills, killed others, and stabbed his benefactors in the back. If I don't have talent, I will absorb other people's cultivation. If I don't have blood, I will rob others of their blood. Since you all want me to die, then I will... Kill you all!
