The essence of the "ant nest": The ant nest is not an artificial alien space, but the body of a sleeping ancient being. The nine-layered structure corresponds to its nine organ systems. Every train is part of its circulatory system, the gray water is its outlet, and the station is the node of its organs. All passengers are "foreign objects" that have been swallowed into the body - the immune system will try to eliminate them, and the "anchor" is the only mark that the immune system can temporarily recognize as "self". But the process of collecting enough anchor points and working your way up is actually a process from the digestive system to the nerve center. The higher you go, the closer you get to the core consciousness of this existence - and when you reach the first level, you will understand the truth: you are not escaping, you are walking into its brain.
