Banned Books in Market Town

Modern society, on the surface, is the real world that ordinary people are familiar with, but in fact there is a market and town space between yin and yang - an alien space formed by the gathering of countless ruins of villages that have been forgotten by history and have suddenly destroyed villages/towns. The market town is connected to the real world through specific "forbidden nodes" (ancient objects, folk rituals, moments of death). Only those selected by the "forbidden power" can enter by mistake or on their own initiative.
