Cao Haoran woke up early in the morning and instead of taking his dear wife to the training ground, he sneaked away and instead headed to the imperial library.
There were two imperial libraries in the entire kingdom. The one at the palace was just for show, containing the information that was meant to be learned by the princes and other officials. The ones that were actually meant to be hidden were saved here at the border of all places.
Sure, the border was the most dangerous place to hide something like this, especially the border between the Cao and Xiu kingdoms. But it was exactly because of this that the Emperor took up the risk and dumped all the forbidden scrolls here, safely keeping them all underground.
What's more, only a few people had access to the key to this forbidden library, and one of them was Cao Haoran. Not even the crown prince got the benefit of having the keys to this special place. In fact, the other princes didn't even know about it.
