The old cities, old houses, old ancestral halls, century-old streets, and abandoned old school buildings remain in the world.
There is an invisible lingering relationship with old shadows:
People who have too deep obsessions and unresolved grievances will be entangled in the past. When they walk into those old places, they will fall into the "illusion of the past"——
It's not about cultivating immortals and fighting monsters, it's about being trapped in other people's old memories, unable to get out, and finally disappearing quietly.
Intention: Time and past events
