[Single heroine + invincible protagonist]
When ghosts wander around the world for a long time, they will bring chaos to the world. For this reason, the underworld has set up the position of yin and yang envoys to eliminate evil ghosts and transform good ghosts.
As the only strongest yin-yang envoy who can freely communicate between the human world and the underworld, he was accidentally involved in a shocking conspiracy during an ordinary ghost-catching operation. Unfortunately, what they encountered was the strongest yin-yang envoy ever, a super bug who gathered all the power of gods and ghosts - Ji Ming.
