The underground of Wanxian City is akin to the sewers of the modern world.
This is the underground world that has existed since the creation of Wanxian City.

This was the gate to the underground city.
"Everyone, once you open this door, a straight path leads to the underground spirit pond of the Central City. Here is a map in front of me; please take a look before you enter."
