Xuanhuan: I'm the Villain Across All Realms

According to the law of conservation of energy, I eat, poop, and keep eating; I eat, poop, and keep eating; I eat, poop. That's why I'm not fat. Then one day, I got a System... So there's no way I could get fat now. That's why I got stronger. That's why I do whatever I want: wherever I go, that's the center of the world. This is my first time writing a book, so it might be a bit rough.
