It was impossible to sell off the military forces within Du You's territory; that was the rule. However, the pets raised in the territory and the battle machines manufactured there could be sold, and that too was the rule.
If it was a technological type of territory, then all the technological type weapons could be sold en masse, but the staff could not. This was why territories with technology types developed most easily on Earth.
Regrettably, Du You hadn't chosen this path from the beginning and hadn't considered these problems; otherwise, he certainly would have figured out a way.
In the following time, Cloud City fell into chaos. First, a large volume of technological goods were sold to themselves, and thus, Du You's Yao River City also obtained a large number of urban technological goods. Items such as police monitors, flying machines, various small robots, some firearms, and all kinds of ordinary single-soldier weapons and so forth.
