Therefore, Wutugu became the vanguard of Yizhou. For the civil officials, a military general like him, who had a problematic mind but was highly capable in combat and easy to control, was quite necessary.
Latterly, as the situation developed, it basically turned into a map-crushing scenario. The last of the Southern Barbarians, incited by Zhang Su and others, were all taken down one by one, and those who weren't killed were gradually subdued by the aura of Zhang Su and others in this battle.
Of course, in Zhang Song's view, it was merely following Yizhou for a meal. The further south these barbarians went, the worse they got at farming. They couldn't even level the land, a disgrace to humanity.
So the further they went, the easier it became to subdue them. In the end, Zhang Song and the others realized they had actually pushed beyond Yongchang Prefecture. But by this point, how could they possibly admit to attacking another country? Surely the map was wrong.
