The trial grounds in the Sea Demon Royal City were a bit like the Thousand Star Proving Ground and the three Holy Lands in the Thousand Star City.
The difference was that in these trial secret realms, strange things like losing memories wouldn't happen.
In the center of the White Shell Royal City, there were five teleportation arrays. According to the difficulty of the trial, they were respectively simple, ordinary, difficult, purgatory, and forbidden areas. According to the color of the teleportation array, there were five colors: white, green, blue, purple, and black.
Each of the five teleportation arrays had a diameter of about 100 meters, and the simple and ordinary teleportation arrays often sent people in and out.
In the White Shell Royal City, everyone needed to go to trial. This was compulsory. So all these trial secret realms, under normal circumstances, had been open all the time so that people could enter at any time.
