Empty Truth

If possible, I hope the OP is "Artillery" ED is "Becoming Insane" By the way, those incredible weapons of Wuji will be described and analyzed in detail in a series of subsequent works, a civilization, a technology, a concept, and a legend. I have conceived a lot of stories, and I am most afraid that someone will write them before me, or even make them before me. In addition to science fiction technology, there are also a lot of illusions of social behavior patterns and a lot of other world views. If I think about it well, it will be very amazing. These two songs are the inspiration for the entire Void Principle. Without them, there would be no Wuji.
