No matter how prosperous the city is, there will always be unknown places that have been forgotten by the predecessors and have never been heard of by future generations.
Maybe there is a mountain in the city we live in that we don't know about, and even its existence is a problem. There is an ancient city on the top of this mirage-like mountain.
The ancient city is more than 10 meters high. Looking up, the city gate is engraved with the words "Funeral Home". I don't know whether it is a mistake or intentional, but the word "Gu" is taken from "Funeral".
