I Build an Underworld in the Human World

(Invincible Literature + Easy + System + Urban + Myth) I have traveled through time. I dug up a "Book of Heaven" under the overpass. With the golden finger in my account, I can see things that others cannot. It turns out that the road from the human world to the underworld is blocked. The road to reincarnation is broken, and evil spirits are wreaking havoc on the world. I want to build a new underworld in the human world to imprison all kinds of wandering ghosts, monsters and monsters. First of all... I have to decide on the candidate for Black and White. How about one boy and one girl. Well, and Mrs. Meng, she must be beautiful.
