The battle in the Central Plains right now, aren't just princes fighting against each other using Yan soldiers.
The Hu people become their mercenaries but they did not get any pay, did not get any titles, did not get any lands. All they get is leftover food from the Yan people
On the south, the Shanyue people is treated even worse and the Nanman tribe is oppressed.
A life like that...should be avenged.
But there is this ambition ins Tuge hearts but no ability to make it a reality. He did not know where to start
He learned that when Aeryon defeated the tribe, he united the tribe and then expand the tribe. The grazing area become larger, the sheep and cattle become numerous. Rewards are bountiful, prosperity abounded
Tuge knows how to fight. He knows how to kill. But he does not know how to administer people.
After all, Tuge is just a common person with no education
He does thing according to his heart.
