My Fantasy Journey

Yan? ? ? Mecha civilization? Technological civilization? Cultivation civilization? Maybe this is the process that a civilization needs to go through, just like people, they experience birth, old age, illness and death. I don't want to be nosy, because I don't want to interfere with the natural development process of a civilization, which is the most boring thing. There are thousands of worlds in this world, and I want to see them. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
