There are two generals in the underworld, one is called Bai Wuchang, and the other is called Black Wuchang. The two Wuchangs and the Bull-headed Horse Face are important figures in the operation of the underworld, and both are indispensable.
Helplessly, Bai Wuchang mistakenly seduced his soul a hundred years ago, causing irreversible consequences, and finally he was reincarnated.
The underworld, which was short of an impermanent person, unexpectedly encountered a once-in-a-millennium gate of hell that opened. Ghosts and ghosts fled and died, causing considerable turmoil in the underworld that was short of people for a while.
In order to fill Bai Wuchang's vacancy, King Diguang decided to second a semi-immortal person from the human world to temporarily assume Bai Wuchang's position, and promised to grant him any wish after the ghosts in the underworld return to their respective places.
Unfortunately, our King of Diguang caught the wrong soul, because the gate of ghosts was wide open, and the small worlds of all parties overlapped for a moment. The ghost he caught casually was just an ordinary soul, a product from the 21st century.
In a word, let alone catching ghosts, not even people.
PS: I borrowed this setting. I haven't read the book. I just think this setting is convenient for doing things.
