Tomb Immortality

This is a strange world where "grave robbery is the cultivation of immortality". The spiritual energy between heaven and earth is exhausted, and only the remains and magical weapons of ancient monks are buried in ancient tombs. Tomb robbers are called "spiritual diggers". They dig up ancient tombs and devour the remaining "corpse energy" and "aura" of the tomb owners to strengthen their bodies. But the price is that every time you go to the tomb, you will have a little more "yin evil" in your body, and you will eventually either turn into an undead zombie, or be taken over by the resentful spirits in the tomb.
