Spiritual Qi Revival: I've Infiltrated the Monsters

This is an era of spiritual qi revival, as a mysterious force rises and gradually envelops the world.

Supernatural lifeforms, an undying race, mysteries in the deep sea, underground demon lairs, waves of ferocious beasts...

At times like these, there's always a handsome fellow wearing an "I'm harmless" smile~

"Don't shoot, I'm one of you!"

Monsters: ???

After awakening the undercover System, he gets stronger by infiltrating monsters and causing trouble among them.

He plants his flag, raises his arm, and shouts: Are kings, nobles, generals, and ministers born to be so?

After he gets all the monsters killed, he lights incense and looks up at the sky.

Kill and rob, earn a golden belt; build bridges and roads, leave no bones behind. The world shouldn't be like this.

Sorry, I'm a cop!
