The Trial of Illusions is held in the forbidden area of the Great Brightness Temple—the Fire Soul Tower.
The Dabei Clan has a total of one hundred and eight grasslands, each hiding a seal deep underground, which suppresses the Fire Soul Clan.
The seal is a passage suppressing the Fire Soul Clan, a perilous place where even an Immortal Emperor might perish. Ning Fan was once captured by Sanyan Demon Child Meng Zhen and taken to the Southern Frontier Steppe's underground seal. Meng Zhen originally intended to throw Ning Fan into the seal to be burned to death. However, Ning Fan outsmarted him, causing Meng Zhen to fall into the seal and die.
