There are quite a few characters on the page, and Li Zhiyuan even needs to piece together the context to guess what they might mean.
After quickly flipping through more than a dozen pages, he realized that the layout of the text on each page was inconsistent, and the titles of the volumes and chapters were not at the beginning of the right pages, but mixed into the content.
An image emerged in Li Zhiyuan's mind: a person, with their left hand turning the pages of a set of exquisite books while the other hand rapidly copied onto a blank book in front of them.
As they wrote, they also kept looking around vigilantly, fearing someone might come.
Thus, this must be a pirated copy of a book.
Li Zhiyuan then flipped through "Qin's Jiao Observation Method" and skimmed through it—indeed, it was also pirated, just as its counterpart.
This almost certainly confirmed that these two sets of books had nothing to do with Liu Yumei.
