According to common sense, just by casually flipping through the research room, you can at least find seven or eight of Qing Chen's assignment books; summer and winter vacation homework is absolutely inevitable.

Moreover, Qing Chen has been on a long break from school, and his textbooks were taken away long ago and sold as waste paper by Nan Gengchen.
K might've been a bit bewildered at that time, as it wasn't a Transcendent that defeated his Taboo, but a rag-and-bone man.
Speaking of the other Taboo, Qing Chen is considering a question, if this item were in K's possession, then the other party should've already written him off.
So why hasn't he?
