“He was a book.

He was a book of scriptures.”

His cover was made of the skin of those who hold a grudge against humans.

His words were written with the blood of those who hold a grudge against heaven.

His weave was created from the sinews of those who hold a grudge against earth.

The heavenly demon, the ruler of darkness.

Yeon Sang-hyeon, who signed a contract with the ruler of darkness at the last moment of his days, is now rewriting his own destiny.

The Heavenly genius met The Heavenly demon!
