Interestingly, these two-dimensional creatures also had internal and external structures. From a three-dimensional perspective, their exterior was a sealed ring wrapped in lines, while their interior was not empty as one might imagine, but formed from many curled lines.
From a three-dimensional perspective, their internal structure was made of lines arranged according to some kind of pattern, packed densely together, looking like a maze woven from countless balls of thread.
Their brain structure was even more incomparably complex. Even when viewed from above from a three-dimensional perspective, it still felt like an intricate circuit board, delicate and complicated. Inside, winding, twisting lines overlapped one another, interweaving, connecting end to end or bending into structures of different shapes, as if countless square mazes had been assembled together.
Well, assuming that complex internal organ was a brain.
To figure out exactly what the thing was, the scientists of the various civilizations in The Great Voyage Organization deliberately observed it for a long time, and discovered that the organ with the most complex structure was indeed the brain.
Most interestingly, their brain structure was not fixed. Instead, as external information was taken in and as they carried out their own actions, different changes would appear within the structure.
Specifically, certain originally closed maze structures became open, while certain openings became closed. This change was like a movable triple circuit switch drawn on a computer plane, able to be flipped from one contact to another, connecting the circuit at the other end.
The scientists believed this was the underlying logic of the two-dimensional people's thought processes. When they thought or acted, information in their brain regions would flow as these "gates" opened and closed, thereby achieving the effect of information transmission.
Interestingly, this transmission of information was also a kind of microelectrical signal.
