Abyssal Game Players are the key to entering the Abyss Fourth Layer.
Wu Chang mulled over the information revealed by the All-Knowing Crystal; this sentence reveals two pieces of information.
First, entering the Abyss Fourth Layer is extremely difficult; some conditions must be fulfilled, and merely having enough power is not enough to be promoted to enter.
Even Leman, a Great Evil God with various authorities and followers spread across various planes, cannot easily enter it.
The second point is the existence of players, or rather the existence of the Abyssal Game, is closely related to the Abyss Fourth Layer, at least as one of the paths to enter the Abyss Fourth Layer.
This connection might be related to what Kristen mentioned—the mutual selection between players and the Abyssal Game.
It's not enough just to be players; the players serving as the key should also meet certain conditions.
