With half a game of chess, I vanquish all demons!

This is one of the celestial realms, the Demon-Slaying Realm! It's a world where legitimate martial artists can travel to the lower realms to undertake demon-slaying missions. It's a world where cultivation techniques are scarce, and the acquisition of personal power is monopolized. Ordinary people rarely obtain legitimate martial arts cultivation methods.

"What? Martial arts? Monopoly? Give it to me!" While others were still diligently practicing martial arts for the qualification to slay demons in the lower realms, Zhao Yao, with these sixteen pieces, was already wreaking havoc in the lower realms. "What? Cross-border law enforcement, interdimensional fishing, subject to the constraints of the Heavenly Dao, and even those who summoned me are constantly trying to trip me up...
