Xuanhuan: Playing the Underworld King from the Start

The protagonist transmigrates to a fantasy world and obtains an Acting System. With absurdly good luck, his very first role is the Underworld King, and the entire world undergoes a tremendous change.

The leaders of the great holy lands: Lord Lion King, please don't come again. You've already stripped us of all our resources.

Formation masters: I thought I'd reached the pinnacle of formations and could look down on all the heroes. But after seeing the Cloud Bat Formation, I realized I may never even have gotten started.

The Underworld King: Now that I have awakened from my slumber, it's time for this world to have a new ruler! I am the Underworld King, so this place shall become the Underworld!
