Cangwu Immortal City.
Outside the Cave Mansion Area, there is a palace situated.
The palace is called 'Flying Immortal Hall', which is the place dedicated to the sale and purchase of cave dwellings in Cangwu Immortal City.
Moreover, every million years, the owners of the cave dwellings must return to this palace to replace the jade token used for entering and exiting their cave dwellings.
This is done to confirm the identity of the immortals residing in the cave dwellings.
The cultivation environment within the Immortal City's cave dwellings is extremely beneficial, so after many owners pass away, their Cave Dwelling Jade Tokens often fall into the hands of others.
With the jade token, those who are not the cave dwelling owners can also enter and cultivate.
The replacement of the jade token every million years is therefore meant to re-verify the identity of the current residents of the cave dwellings.
Flying Immortal Hall is divided into four layers, occupying a vast area.
