Wu Jinhai was actually not a person who liked to study. Since childhood, he often spent time outside the palace, and that's why no one could force him to study. It was fortunate that he grew up as a smart man, and maybe he needed to thank his parents for the good genes he received from them both.
He didn't like studying, but tonight he stayed up all night just to study. There were two good reasons for his sudden behavior change. The first reason was that he was now the Crown Prince of the empire, and learning every detail about his country was indeed his responsibility.
There was the first, so of course, there was the second. The second reason why he suddenly dedicated himself to studying, was because he was trying to divert his attention so that he didn't carelessly leave the Xinyang Imperial Palace and travel somewhere. To be precise, he would probably go to Dong Lang and meet someone there, but he couldn't because there was still a ban on Dong Lang due to the full moon.
