Even Lin Yi wasn't able to derive anything useful from these incomplete books. These books were useless if you were to say they were valuable.
However, they were really valuable!
No wonder the array and talisman sub-school existed in name only. If one wanted to learn something from these fragments, they really needed to have the spirit of a foolish old man moving mountains.
Lin Yi wasn't a fool, but in his sea of consciousness, with his extraordinary speed and wisdom, he could easily complete the mountain moving work. All the fragments were rearranged and filtered one by one.
After eliminating the parts that couldn't be pieced together, he actually obtained a relatively complete ancient book on talismans and formations, and it was still incomplete!
However, this incomplete piece that was pieced together could at least be understood by others. Moreover, it was relatively smooth, and there was nothing wrong with it on the surface.
