Ye Fan traveled through time and became the youngest warden of the Heavenly Prison in the Dayin Dynasty, but because he offended the powerful, he was demoted to the ninth floor of the "Devil's Heart Cave" where peerless evil spirits were imprisoned.
When he was in a desperate situation, he accidentally awakened the Gu God cultivation system, using the resentment of the abyss as fuel and thousands of Gu insects as blades. Since then, the style of the Demon Cave has changed: the violent troll has become a janitor, the poison master is willing to make elixirs and test medicine, and the cold-blooded killer has become a shadow blade...
He uses modern thinking to manage this dark Jedi place, and uses Gu techniques to game the court.
Until one day, the empress on the dragon throne came to the abyss in person. Ye Fan chuckled and asked, "Your Majesty, do you also want to make a deal with me?"
