It was only two days later that Rosen successfully occupied six gold mines, mainly thanks to the efforts of the Goddess of Vengeance and Xiaohai.
After sending workers to occupy all the gold mines, Rosen focused on checking the main city and found that there were enough resources to upgrade to a level two main city, so he immediately took action.
After the level two main city upgrade was completed, he upgraded the barracks to level two, allowing him to summon level two units.
There were plenty of remaining resources, and the growth rate was rapid.
Rosen promptly unlocked the level two units named Dragon Knights and summoned a large number of them.
A total of thirty Dragon Knights.
With the setting of flying units ignoring ground close-range units, as long as the invader does not bring many flying units, it is sufficient to deal with them.
"I need to quickly upgrade to a level three main city; then, when I summon defensive towers, real security can be guaranteed."
