Chaos Reigns in Superclusters

Also known as "The Nine-Level World that Becomes a Villain", it tells a future universe world of technological magic and even cultivation. It is mainly narrated from the first perspective and narration. The protagonist is called Chen Gong, a time-travel kid who picked up an artifact (actually, it has nothing to do with time-travel), and Liu Ruyan is the youngest sister in the rebel army. There are also the chaste descendants of the original demon king, the invincible goddess who wants to take charge of a super star group, etc. Here, the flow of time is very fast, and the loss of population is very rare. Ah, it is a newbie's work, so the writing does not have so many details, but it is like a bunch of outlines.
