I'm Working as a Ghost in the Underworld

I accidentally picked up a mobile phone on the road, and was told that it had become a ghost. The first task is to capture the evil ghosts who escaped from the underworld. Zhang Fan was panicked because he didn't know how to catch ghosts. "Ding! The underworld system is successfully bound, and the host obtains the primary ghost-catching technique and the primary ghost form." Fierce ghost? Grasp! Thousand-year ghost king? Grasp! Ghost bride? I can't catch this one, so I signed a contract to be a little maid. ... "Master Zhang, a peerless ghost has appeared in the Three Realms. He wants to train a living creature to break through the Ghost Emperor. Please take action to contain him!" The King of Hell led a group of ghosts and gods to request.
