The North borderline was a vast area, and not heavily populated. Moreover, wars occurred yearly, and life was hard for the people.
For the past twenty years, the imperial family of the North, under the advice of the Sages tribe, had agreed to examine and cultivate their character. They were determined to encourage their citizens to reproduce and have descendants, actively open new properties, and do business with merchants from other countries.
Without a doubt that was the correct political strategy, as the tribes of the North borderline were bustling and full of excitement, their country strong onat all fronts.
They launched a surprise attack at the borders of Dongqing ten years previous, thereby occupying Chongzhou, Shangyu county and its three cities. This made bold the fighting spirit of the soldiers from the North borders, until they feared no one. They even assumed they possessed the ultimate power in the central plains to dominate the land.
