Hang Yu did not wish to confront Celestial Desolation City.
On one hand, Celestial Desolation City is very powerful, and even though Sand Spring City is developing rapidly, the difficulty of fighting it remains very high, with no hope of surpassing it within two to three months.
On the other hand, Hang Yu has no significant desire for Celestial Desolation City or the position of Governor of the Wilderness. Whether he takes Celestial Desolation City or not doesn't matter to him.
Celestial Desolation City is indeed the best city in the desert.
However, the quality of a Spirit Realm city is merely a matter of the extent of its territorial holdings and the abundance of resources. Behind Hang Yu is a world of billions of humans, so the demand for one city or one piece of land is not as strong.
The fight for the Governor position has started too early.
There is no benefit to Hang Yu in doing so.
This will only make the Azure Dragon draw attention from Mist Dragon City too soon!
