Demon-Defying City.
When this city was initially constructed, besides the main gate, Grandmaster Yu heeded Fu Changsheng's suggestion and also established a side gate in each of the east, south, west, and north directions, as well as a secret gate.
Usually,
people within the city could enter and exit through the side gates.
When danger loomed outside, the side gates would be sealed, while the secret gate was set up for travels like theirs now.
Steering the Flying Ship, they activated the ship's Invisibility Restriction, and upon exiting through the secret gate, the Tai Chi Locusts outside noticed nothing amiss.
They were responsible for the southwestern direction.
