Some of the worlds in the Monument are generated by the system, and some are constructed by all those who have access to it. What the system generates is nothing to say, but what the user builds is very complicated. This virtual world integrates all the world information that the accessor thinks about, and will feedback and develop based on the accessor's behavior, just like the real society outside. Every virtual world built by users carries the shadow of the society in which the users live at that time.
"But the virtual world is not the real world after all. It can be said that users of different eras end up living in the reverberations of the times they live in. At first, we thought that the society in these virtual worlds would develop like the real world, so when the first free world obelisk was built, surveillance was connected to record the social evolution inside. Disappointingly, hundreds of years have passed, and the world in the first obelisk has not changed much. If we had not updated some world information, it might still be as it was when it was built."
Concept: The introduction is written casually, I want to build a world.
