Demon King Incubator

My name is Cheng Shu, and I have traveled to a different world where spiritual energy is revived. Even if I am a demon in this life, I will still strive to be a good demon! I heard that there was a group fight between demons on the hill next door, so I went to beat their leader until he couldn't get out of bed, so that the two parties would not be harmonious. It was said that an ancient ruin was about to be discovered somewhere, so I emptied the ruins in advance to avoid a bloody fight among everyone. My wish is world peace. These monsters respect me very much and call me the Demon King.
