The Demon Lord is the supreme being of the Demonic Way. Luo Chi's starting point is to travel through time and become a demon lord. Okay, with such a high starting point, I don't want to work hard.

The righteous people in the world are taking advantage of the fire and want to kill me to eliminate future troubles forever? Don't force me, really, I have a system. Fight the villain to the end! If you want to do it, be the biggest devil in the world!
