After the summer, the grief caused by the death of Snake Ci gradually dissipated in the palace, and it was basically determined that the natural disaster was quickly subsiding, and the women in the palace were all moved.

This year is the ninth year of the Xia calendar, Su Yan is forty-two years old, Xiangxiang is thirty years old, and Su Yan's two sons and those daughters-in-law are nineteen years old.

The age is older, the natural disasters are also subsiding, and they all have the idea of having children, even Meihua and Eyue want to have another child, if the women are pregnant this year, Su Yan's son and grandson will be born almost at the same time next year.

Thinking that his son and grandson would be born together, Su Yan felt a little embarrassed in his heart, but women didn't have so many ideas, and this was the case in Xia Guozhong, and only Su Yan, who was a human being in two lives, would feel embarrassed.

So, after the summer, the women are pregnant one by one, of course, not all women are pregnant, if all the women are pregnant, they will all have a big belly at that time, Su Yan can't take care of it alone, so he can only call some women from outside to take care of them.

In the end, as a sister, Meihua took the initiative to give in, this year let Eyue and Xiangxiang first, and wait for the next year after the two sisters give birth to a child, Meihua will conceive a child.

The same is true for Hei and An, who both have five wives, and eventually two wives are waiting to conceive a child next year.

Fortunately, there is no such system of "primogeniture inheritance" in Xia Kingdom for the time being, otherwise just competing for the order of pregnancy will turn the family upside down.

In addition, it is very convenient to be a martial artist, a martial artist can control his body better than ordinary people, and in today's era of lack of avoidance/pregnancy means, a martial artist can solve this matter as long as he controls his body.

……

This year, the Xia Kingdom built a total of three cities, one is located in the Yan clan's hometown, and the other two are built on the east and west sides of the Xia Kingdom's local area, continuing to expand the territory of the Xia Kingdom.

In the early spring of this year, the population count continued, and there were more than 28,100 adult male nationals, more than 39,800 adult female nationals, and a total of more than 159,900 nationals, almost reaching 160,000.

You must know that last year, the total population of Xia was more than 148,100 people, and in one year, the total population of Xia increased by more than 17,000 people, which is not a small number, and the total population of the Japanese tribal camp is not as large as the population increased by Xia in a year.

The population has increased, and the desired living area and food must be appropriately increased, because of natural disasters, for two years, the Xia Kingdom stopped building cities, and in two years, the Xia Kingdom can build at least four cities, and if it is more, it can build six to eight cities.

Even the smallest four cities can accommodate a minimum of 20,000 and a maximum of 40,000 people, while also expanding the area of arable land.

Based on the fact that the current twenty-one cities of the Xia Kingdom can accommodate more than 165,200 people, the average number of people living in each city is nearly 8,000, which is a lot more than the population of about 5,000 people in each city set by Su Yan at the beginning, but fortunately, each city can accommodate a maximum of 10,000 people, so there is no problem.

The natural disasters are subsiding, and the new population of Xia Kingdom will increase more and more every year, which makes Xia Kingdom need to build more cities, build three cities this year, and next year Su Yan plans to build four cities at the same time, with the construction volume of ordinary cities, it will not be a problem for Xia Kingdom at all.

The duration of the past winter has been reduced to one hundred and fourteen days, and the duration of the next winter will continue to shorten, and there is no problem in completing the mission.

However, there is one point that Su Yan has turned into a key point, that is, the new city built on the edge of the grassland in the early next year, Su Yan has already given this city a good name, the single word "storage", storage city, the city of cattle and horses, the name shows the main role of this city, and the city closest to the storage city and is under construction was named "Yan" by Su Yan to commemorate the hometown of the Yan clan.

Located on the edge of the grassland, with the grassland in the west, the jungle in the east, and the main trunk of the Yellow River in the south, the city is responsible for the Xia State to store cattle and horses, and may encounter attacks from the enemy on the grassland, the importance is self-evident.

Therefore, Su Yan thought about raising the standard of the city, building a strong city rooted in the edge of the grassland, and no amount of enemies could break through the city.

According to Su Yan's vision, the scale of the city will be the same as that of the standard city, and the place to raise the standard is the city wall, which needs to be two feet high on all sides to resist the cavalry raid, and if the city wall is short, the cavalry may ride over the wall.

Improving the construction standard of the city wall will indeed increase the construction time of the city, but the importance of the city is worth doing, and it will even expand the city in the future, after all, the geographical location of the city is too good, the west is the grassland, the east is the jungle, and the south is the main trunk of the Yellow River.

The city of Xia can not be built in the grassland area for the time being, residents need a lot of firewood and grass for cooking and winter to resist the cold, there is very little firewood in the grassland, it is very troublesome for the Xia people who have not lived in the grassland area, and they have to take it step by step, for example, the coal mined in the Yancheng area in the future is a better fuel, which can be burned and used.

As the first summer was about to end, Su Yan summoned Hu Nan, Yue Mao and other four people to Zhongjing City, and ordered the four of them to form a team to go to four areas to choose sites to build new cities, of which Hu Nan was responsible for the task of storing the city.

"Hunan, your task is the heaviest, be careful of the nomadic tribes on the grassland."

"Yui"

Su Yan's words are not a joke, you must be careful of nomadic tribes to build a city on the edge of the grassland, maybe one day there will be a nomadic tribe attacking, almost no farming tribes are found in the edge of the grassland, and the farming tribes that lived before were either wiped out by the nomadic tribes, or they were scared away from that boundary.

There is no way, if there is no strong bow and crossbow, it is almost impossible for the infantry to block the surprise attack of the cavalry, fortunately, the Xia State has always attached importance to the development of bows and arrows, and even the Ministry of Industry has made a relatively simple bed crossbow, and after the bed crossbow is perfected, it must be installed on the city wall, and at the same time, the city should be equipped with more archers, as well as the cavalry troops belonging to the Xia State.

The cavalry tribe of the Xia Kingdom, equipped with strong bows, will one day crisscross the grassland.

Su Yan handed over the task to Hu Nan, Yue Mao and the other four, and the four of them immediately took action, first gathering a hundred or two hundred people to go to the target area to investigate, select a suitable place to build a city, and then carry out some preparations before building a city, such as building a dock, building a Lin family's residence, determining whether there are other tribes in the surrounding area, and so on.
