Reincarnated in Another World, Immortal and Undying, Yet Still Full of Regrets

The first part of "Reincarnated in Another World: The Undying Witch"

My name is Luo Li. I'm a student at a junior high school. I've seen people cultivate immortality and live forever, but I'd never seen anyone start out in another world being tortured by goblins, nearly dying, while the System only gave me immortality. If it had given me long life but not immortality, I'd have known what the System wanted. As long as I could keep my head down, as long as I stayed alive, then even if they were gods, I could still take them on. After ten thousand years, a single drop from my fingertip became the leader of the Church of Sin. A disciple I casually taught became the divine ruler of an empire. The gods you see, the divine trees you look upon, are only things I've encountered over the years. You say I'm crazy? Then I am. Trapped on an unchanging path of immortality, even if I'm a witch, I am also a god.
