The Main God's Garden is actually the inner world of a middle-level Main God within the main plane. After its fall, this great world remained and still retained the complete Main God Law.
As for why that Main God would fall in this Basic Plane, no one knows. But its inner world was only discovered by powerful humans in the Ancient Plane.
At that time, humans were at their strongest, and there was even a Main God seated in the Basic Plane.
After an initial exploration, upon discovering the extraordinariness of the Main God's Garden, the human Main God reinforced its position and applied multiple sealing techniques.
Afterward, the Main God's Garden became the most secretive Secret Realm of the Human Camp, and only those who truly made significant contributions to the Human Camp could enter.
