Reborn as a Madman of the City

What is the Nine Netherworlds? What is the Illusory Realm?

What is an immortal? What is a demon?

What is yin? What is yang?

The great Demon Emperor Li Feng is reborn in a completely unfamiliar world. First astonished, then gradually learning to fit in, he finally comprehends the Way of the Nine Netherworlds and Illusory Realm on the brink of life and death. From then on, he enters a world he had never even imagined.

While others cultivate immortality, he cultivates demonic arts. Who says the righteous rise one foot while evil rises ten?

He will become the ultimate mad demon of this new world.
