I Drank with the Third Young Master of the Demon Emperor

(No heroine) After Chenze died "accidentally", he was reborn in a chaotic world. In order to prevent himself from dying "accidentally" again, he started his own practice. When he had become invincible in the world, creatures outside the circle began to massacre and enslave humans and monsters. As the strongest human being, Chenze teamed up with the three young masters of the Aolai Kingdom to resist the creatures outside the circle. At this time, the ruler of the creatures outside the circle negotiated peace with the two leaders, and the world was finally divided into the inside and outside the circle. "If I hadn't been with you for so many years, I would have thought you were a monster." "Hahaha, maybe, let's stop talking and drink." (Derived from anime)
