The abnormal region within Persian Sovereignty has an external contour with a maximum diameter of approximately 40 kilometers, approximating a circle. However, the internal diameter shrouded in "fog" exceeds 300 kilometers, resembling the shape of a large pear.
This means that the exchange of the surface area between the unknown planet and Blue Star is not one to one but rather nearly one to eight.
With such vast differences in the surface areas exchanged between parts of two different planets, considering the involvement of spatial rules, it's actually not that surprising.
The S-Class Space Ability User isolated the entire abnormal region using psi skills, leaving only an entrance and exit facing the Giant Battleship for the free passage of ground personnel, vehicles, and aircraft. All other directions are impassable, like a mirror; you enter here and exit there. Attempts to forcibly break through are futile as ordinary psi skills offer no use.
