Xu Daofeng wanted to introduce Chu Mu to Chief Officer Lu. Indeed, the independence of a territory, no matter where it was placed, was a significant matter. Regardless of the size of the territory, once independent, it implicated the dignity and POSITION of Cloud Realm's rulers. Especially in a region that was already unstable, if someone spearheaded independence, it could likely trigger a territorial uprising, something the rulers definitely did not want to see.
Xu Daofeng also told Chu Mu that while the existence of territorial independence was recognized, the first one to achieve independence would absolutely become the target of all rulers, who would spare no effort to crush it. They could not allow such a leader to emerge, seeking to squelch any nascent desires for independence among others through the example made of the first.
