The Yin-Yang Demon Emperor: Starting with My Defection from the Demon Suppression Bureau!

[System] [Morally Ambiguous] [The protagonist won’t stay at the Demon Suppression Bureau forever]

Wang Yuan transmigrates to a world of demons and monsters, becoming a prison guard in the Demon Suppression Bureau’s underground prison. He also awakens a Trade System.

As long as he kills a demon or monster, he can trade its corpse. He also discovers that silver can be used to improve his cultivation.

He thought this ability would let him thrive in the Demon Suppression Bureau, but after killing a colleague with powerful connections, he finds himself hunted by everyone.

With no other choice, Wang Yuan flees the Demon Suppression Bureau and begins wandering from place to place.

Thus, the Yin-Yang Demon Emperor is born.

“What? Your sect has a mountain of rare treasures? Hand them over, they’re mine!”

“What? You bullied me when I was weak, but now I’m powerful enough to crush your empire. You say I’ve gone too far?”
