I Built an Underworld in the Mortal Realm

(Invincible protagonist + lighthearted + System + urban + mythology)

I transmigrated.

I dug up a “Heavenly Book” beneath an overpass.

My golden finger had arrived: I could see things other people couldn’t.

It turned out the road from the human world to the underworld was blocked.

The path of reincarnation was broken, and evil ghosts were running rampant in the human world.

I was going to build a new underworld in the human world to imprison all kinds of wandering spirits and monsters.

First...

I had to pick the right candidates for Black and White Impermanence.

How about one man and one woman?

Oh, and Lady Meng had to be beautiful.
