During this time, Du You hasn't continued to expand, or rather, he's been constantly expanding in the Eastern region, or you could say he's been assimilating. Anyway, the entire Eastern region is now nominally his.
Even if some people don't want to join, as long as he sends an envoy over, they have no choice but to join.
Otherwise, if the army moves, it would be a deadly affair. Du You will not allow others to toy with him, nor does he have the time. Anyone who refuses the first time is an enemy.
In subsequent battles, even if those who once refused choose to surrender, Du You doesn't spare them and executes them directly. Because of the examples set by a few individuals, no one else dares to feign compliance afterward.
At the very least, those unwilling to surrender would only run away immediately rather than stay in that place.
