Generally, the Child of Chaos possesses the strength of the Star Abyss Eleventh Layer Peak, and tens of thousands of Void Demons are all at the Star Abyss Eleventh Layer, illustrating how exaggerated the difficulty is.
Moreover, there's the oppression of the Cosmic Will, which can only exert a fraction of one's power.
Furthermore, one must kill all the Void Demons to pass, which further tests the comprehensive strength of the Child of Chaos.
If one's Will isn't high enough, the life preservation isn't strong enough, Speed isn't quick enough, the enemy killing isn't rapid enough… these factors could lead to not passing the test.
Therefore, with the strength of these Children of Chaos from the Void Sea in the past, if multiple people worked together, there was still a slight hope to pass the forty-ninth layer.
For an individual, it was nearly impossible to pass.
