With the Book of Life and Death and Yin-Yang Eyes, I Am the Underworld’s Spokesperson!

Wu Cheng died of an illness, but who could have guessed his allotted years weren't up, and the King of Hell wouldn't let him die?

Do you want to come back to life? There's only one way: work for the underworld!

Wu Cheng: No, no, no! I'm a good person. I won't be collecting souls!

Underworld deputy: ...

To keep people from losing all respect for life and death, the underworld needed someone to walk among the living and spread the word about the afterlife.

And Wu Cheng?

He was just a fragile college student who'd lucked out!

Now he was an underworld agent walking among the living, armed with a System and all kinds of special skills.

He had classes and exams during the day, and had to find time to hunt ghosts at night!

Wu Cheng: This is almost as bad as being an office drone!
