Yang Xiaotian perused the books one by one.
He didn't pay attention to the cultivation techniques and holy technique secret tomes but instead focused on those books that recorded the events of the various empires in the Three Pure Continents and the Kaiyuan Empire of that time.
Through these books, Yang Xiaotian gradually gained a clearer understanding of the Three Pure Continents of yore.
At that time, there were thousands of empires in the Three Pure Continents.
Unlike now, there are only a few hundred.
However, back then, the Three Pure Continents were more chaotic than now.
The great empires frequently engaged in chaotic wars.
It could be said that the people lived in destitution.
It was Emperor Kaiyuan who unified the great empires and ended this chaotic era.
Unfortunately, the Kaiyuan Empire only existed for a few thousand years.
