He undergoes a total transformation to emerge as the most fearsome and powerful fiendish demon in his era, that even immortals and fiends are fearful of him, and saints are at his beck and call.
Mastering the Supreme Demon Classic is the turning point in his life. He is able to unleash his immense and divine power from within, illuminating the entire universe!

Chen Heng is called a pervert.

For killing his sexual partner, the dejected gong forced him to bind with a cheap system.

Confessions of the small gong:

My lover is a pervert, he is very violent, arrogant, black belly, and vicious.

I want to break his wings and cut off his limbs.

Capture him, possess him, collect him, and let him be mine.

Small shou: arrogant, cold, black belly, vicious

Small gong: more arrogant, colder, more black belly, and more vicious
