The paper is large, A3-sized, with handwritten formulas in the margins, but in the center is an image sketched with lines.
From a conventional perspective, the image is quite... rugged.
There's no single regular shape on it; some lines twist together like branches, while others are just a mess of scribbles. Yet, for some reason, Su Huan instinctively felt this image was beautiful, even somewhat familiar.
"There are many such images. Initially, Old Xu extracted them using conventional methods, but they were always chaotic. Later, he had the High Priest help look at them, and the latter drew this image. The first time you see it, it might seem inexplicable, which is normal. Old Xu said this is a four-dimensional image."
