I Am the Heavenly Demon Nightmare, and I Grow Stronger When I Turn Evil

A towering black hand tears apart the sky, and countless demons from beyond the realm rain down.

To resist them, ancient martial arts return, and humanity enters the Demon Era, a time of war against the demons.

Those who cultivate martial arts can be invaded by demons at the slightest lapse in concentration.

In mild cases, they devour their own flesh, nourishing the demon while leaving themselves crippled.

In moderate cases, their minds become confused, and nine out of ten of their three souls and seven spirits are lost.

In severe cases, the demon takes over their bodies. They may look like their own kind, but they are enemies in truth.

Zhou Zhen transmigrates into this world and binds himself to a Demonization Battle System. As long as he gives in to demonic possession, he can grow infinitely stronger.

"What? The Demon Wheel Art lets me become possessed every time I cultivate? Fantastic!"

"The Dual Cultivation Mysterious Maiden Art can draw the Desire Demon into my body? Even if the Jade Emperor himself came today, I'd still devour the Desire Demon."

"I never expected the strongest human martial art, the Demon-Shocking Art, to have been created by the Demon Emperor."

"So the entire universe has already entered the Demon Era. It seems fate has chosen me, Zhou, to rise against the heavens."

Countless years later, in the Freely Manifesting Demon Realm, Zhou Zhen opens his bloody maw.

"Demons... swallowed whole!"
