The protagonist Lin Yinan was brought by an inexplicable force to the most cruel Lion Camel Ridge in the world of Journey to the West. During the battle with the little demon, he discovered that he could absorb the demonic energy to obtain his racial innate magical power. By killing the wolf demon, he obtained the racial innate magical power of self-healing. So what innate magical powers would he obtain by killing a demon king or a mythical and legendary figure? Soon his system choice task also came about. He could choose to help Tang Monk and his disciples get rid of the three demon kings to obtain magical powers (invisibility, seventy-two transformations, etc.), Or he could choose to help the three demon kings eat Tang Monk's meat and share immortality.
