When the manifold being named Laqi touched his hand, Li Qi already understood what he wanted to do.
By sensing the shape and surface patterns of his hand, they could read "information." Of course, such information was meaningless, because Li Qi's hand had not been conveying any message in the first place.
Unlike the manifold race, who conversed by folding their surfaces, Li Qi was a Human Race member, and his three-dimensional structure was actually of little use.
Though that was not quite right either. Li Qi's three-dimensional topology—his "appearance"—could also convey certain information, including "expressions," "complexion," "body posture," and "looks." All of these were information expressed through three-dimensional topology.
In essence, a human's three-dimensional topology was equivalent to a donut's.
Because the human form could be folded into the shape of a donut. The human body mainly had two openings, above and below, connected through one passage. Topologically, it was homeomorphic to a donut. If you unfolded yourself from the inside out along the digestive tract leading from your mouth, you would discover that the human body was a donut.
But by folding the donut's surface, one could differentiate fingers, a face, muscular contours, and so on.
As stated before, "folding" could convey information.
When the shapes folded out from the donut that was the human body possessed certain structures, they appeared "handsome" or "beautiful." But if the folding went poorly, they became "ugly," even "terrifying."
That was the information conveyed by the folding of topological structures.
One could even say that all aesthetics under three-dimensional structures were merely different topological structures. One could imagine how much information such folding could convey.
But the human body was ultimately only a three-dimensional topology. Both the amount and speed of information it could convey were limited; this was roughly its limit.
