The Emperor feared that she, as a follower of The Lord, would be drawn over to another kingdom, so he did what he could to remain here in the homeland.
Xingyi Hall was indeed the best school in Feixing Kingdom. However, it was meant to serve the Feixing Kingdom and to nurture elites for the kingdom.
It was heard that the management followed a military routine, as they even had to chant the slogans loudly every day, as though brainwashed.
If she went on to learn in there, she could only stay in Feixing Kingdom. There would be no place left for her to go.
Even if she went to another kingdom, she would be guarded against, like a spy.
According to the legend, The Lord established Tianju Hall a few hundred years ago. All the recruits were the best elites in the entire continent. Even the teachers were selected from each country, so it was definitely a great school. The graduates from the school could easily dominate the whole continent.
