When it comes to this topic, it's impossible not to mention a special concept.
Long before entering this universe and coming into contact with the "Black Silver" Mercenary Group, a native civilization, Human Civilization had tried to make these natives aware of the existence of the Civilization Trial.
To everyone's surprise, the result was inconceivable.
Unrecognizable!
That's right, even if all information related to the Civilization Trial was explained to them face-to-face, all the natives would lose their memories without any awareness, and their cognition would even become distorted.
What was universally known within the entire Human Civilization was completely unknown to the natives!
Unless, the natives formally joined them or one of the two Affiliated Civilizations.
Only then could this cognitive restriction be lifted.
