In this Human World, even if the demon is a Demon Saint, the Myriad Phenomena Demon Thought it can summon has its limits.
Of course, if it is a Heavenly Phenomenon Level demon of the middle rank or higher, then there would be danger, and it might even get trapped and die within the Great Array.
Before the ascension, the Human World did not allow the existence of Heavenly Phenomenon Level Celestials.
The reason why various countries' Martial Emperors were able to become Heavenly Phenomenon Celestials is due to the possession of the National Destiny Artifacts connected with the Barrier Array.
After the ascension, the Human World has allowed the existence of Heavenly Phenomenon Level Celestials.
