After wandering around the Library with Iyas for a while, Yang Yu quickly lost interest.
Although there were many books, none of them piqued Yang Yu's interest.
While it's true that the knowledge here might come in handy one day, accumulating so much knowledge is a daunting and thankless task.
Unless one intends to pursue a relevant profession, much of the learned knowledge only makes one bald, like witnessing a Mediterranean sunset.
Besides, by the time he memorized all this knowledge, Yellow Flower might have wilted, and who knows, the Demon King might have reached his doorstep, banging drums and celebrating the conquest of the world.
"Indeed, to acquire that knowledge, one must become an Advanced Member of the Library."
It's unknown if this Library has any special mechanisms; if only there was a secret passage that allowed moving repeatedly and interchangeably between floors, or a magical all-knowing mirror that directly displayed the desired knowledge.
