[Sir, why don't you build all the other building units before upgrading? If you upgrade with the Lord's Manor only, you will only get bronze treasure chests.]
"Ah!..."
Although he could enhance the bronze treasure chest to give top rewards, the grade was too low and he could only get 3 items.
It was better to strive for higher grade rewards to maximize the enhancement effects.
There was also the issue of upgrading.
If he upgraded the territory first and then built the buildings, he would have to go around upgrading them individually later on.
That is too much work.
It was better to upgrade everything together with the territory.
Anyway, the only thing that he had to pay attention to was the population. According to his calculation, just the 9999 residents present were enough to reach level 14.
If he recruited military units, it was enough to reach level 20.
