Deciding to head back to the sect to avoid the chaos that had spread through the Eastern Central Region during his seclusion, Chu Yang had found himself moving through the territory of the Fleeting Cloud Empire for the simple reason that it was the fastest and safest path leading back to the Northern Central Region. Going through any other major power's territory would come with several risks from wandering into an unknown dangerous location to stumbling onto an active battlefield.
The risk remained when making his way through the Fleeting Cloud Empire, but it was far lower, as he at least knew far more about the layout of the Fleeting Cloud Empire given it was the place he had ended up spending most of his time wandering through during his time in the Eastern Central Region.
Because of this, Chu Yang ended up finding himself being caught completely off guard by the collapse of the Fleeting Cloud Empire. Not at all having expected a major power to collapse overnight.
