Is This a Zombie?

Zombies are born from the resentment and foul energy of Heaven and Earth. They never age, die, or perish. Cast out by Heaven, Earth, and the human realm, they are excluded from the six paths of rebirth. They wander without a home, drifting from place to place. In the human world, they turn resentment into power and feed on blood, using the blood of the living to vent their endless loneliness. Jiang Chen pondered. Are all zombies like that? Then where did these skills come from? Why don't I have them? Am I really a zombie? Well, in theory, I'm not yet a true zombie. At most, I'm just an animated corpse. Though I still retain the habits of the living, my body is rotting beyond my control, inching toward death. Then a letter from a hundred years ago gave me hope of staying alive. To my past self, when you read this letter, you should think that you are starting to turn into a corpse.
