Guardian, I Kill Demons in Both Realms.

Fang Shoujing never thought that his life would be determined by a copper coin. He shuttles between the two worlds of reality and ancient times. In the ancient world, he slayed demons, learned supernatural powers, and rose from a mortal to heaven, pursuing the supreme immortality. In the real world, he eliminates ghosts, bridges rifts, and fights against the apocalypse that can destroy civilization. Only by stepping into the gate of heaven can we know the difference between clouds and mud; only by becoming persistent in one thought can we get a glimpse of the true meaning of the path to immortality.
