In the next 2150, the ghost realm breaks out, evil ghosts run rampant, and humans retreat to safe bases. Lin Zhao, a survivor of the apocalypse, whose parents were killed by a ghost, lived alone in an abandoned city for five years. He accidentally found the "yin-eyed ancient jade" engraved with gossip in the National Museum, and opened the "yin eye" that can see through the ghost's weakness (black air mass on the chest) and the countdown to death. After that, he relied on the ancient jade to kill ghosts and survive, collecting fragments to strengthen his abilities (absorbing Yin Qi to upgrade). He met the museum administrator Su Wan (who knew the secret of the ancient jade). The two went to the base to solve the civil strife and the infiltration of evil ghosts, and gradually revealed the truth - the ghost realm was artificially created by Chen Mo, the leader of the Human Alliance, with the purpose of controlling humans, and the ancient jade is the key to restraining ghosts. Lin Zhao led his companions to use the ancient jade's ultimate ability (controlling Yin Qi) to eliminate Chen Mo, end the ghost realm, and rebuild their homeland.
