Time of city division:
1. Sub-cities are generally built after entering Yongzhou, Yanzhou and Yuzhou, because it is impossible to assign military commanders to the sub-cities. It is a bit uneconomical to build it in the early stage, so it is better to build it in the later stage when resources are gradually increasing.
It needs to consume 25,000 pieces of wood, 25,000 pieces of iron ore, 35,000 stones and 20,000 grains. Because the troops between the sub-city and the main city enjoy the architectural bonus of different cities, they cannot be transferred to each other. When going out, you can choose the main city or the divided military commanders to attack. After the construction of the sub-city, the resource output of the land occupied by the sub-city will disappear.
