Under the leadership of the herdsmen, the Wind Tribe defeated the Black Wolf Tribe, and the Wind Tribe will become even stronger in the future with the large amount of loot obtained from the Black Wolf Tribe as nourishment.

The black wolf tribe, which has a sharp decline in population and a sharp decrease in the number of cattle, horses and sheep grazing, will have to be more careful to live on the grassland from now on.

The herdsman's family officially became members of the Wind Tribe, and their status was almost equal to that of other Wind tribesmen.

As time passed, the herdsmen thought that they would be able to live the life they wanted after joining the Wind Tribe, but they did not expect that the other people of the Wind Tribe were very indifferent to their family, and even ridiculed and ridiculed in person, as well as the hateful gaze from the original Black Wolf Tribe.

Yes, the Black Wolf Tribe was hit hard because of the herdsmen, so many clansmen died, so many clansmen were captured by the Wind Tribe, so many cattle, horses and sheep were snatched away by the Wind Tribe, for the Black Wolf Tribe, the herdsman is a betrayer, a traitor.

Put it to the wind tribe, when the herdsmen are useful, the wind leader and other clansmen will be very happy to welcome the herdsmen to join, and when the herdsmen's usefulness is gone, the wind leader will not care about the herdsmen, the wind tribe has him without him, and the other clansmen of the wind tribe are very disgusted with the herdsmen, since the herdsmen can betray the black wolf tribe that gave birth to him and raised him, will they betray the wind tribe one day in the future.

Several of the higher-ups of the Wind Tribe suggested that the leader kill the herdsman, but the leader did not agree for the time being.

……

It's the second month of summer, and everything is going on in order.

Of the four new cities built this year, two of them are the most important, one is the source city built in the edge of the grassland, and the other is the Li city built in the easternmost part of the Xia Kingdom.

In the future, large pastures will be established around the city to graze horses, providing a large number of high-quality war horses for the Xia country, and the Xia country will also form a strong cavalry force in the city to prepare for the future large-scale march into the grassland.

The first cavalry unit of the Xia State has been training on the side of the city for several months, and the strength is steadily improving, and the size of the cavalry unit will be doubled next year, Su Yan intends to wait until the end of the five-year plan, and the Xia State will form a cavalry force of about 1,000 people, and then march to the grassland.

The nomadic tribes on the grassland have a large number of cattle, horses and sheep, they are the target of the cavalry troops of the Xia Kingdom, even if they destroy a small tribe with a population of only a few hundred, the Xia Kingdom can also obtain thousands of cattle, horses and sheep, sheep are not needed for the time being, only used to eat meat, but cattle and horses are in short supply in the Xia Kingdom.

Trading with nomadic tribes to obtain cattle and horses is still a bit slow, and it is only by sending cavalry troops directly into the grassland to quickly obtain a large number of cattle and horses.

The city was built for the grassland, cavalry, cattle and horses, and the city of Li was built for the shipbuilding industry of the Xia Kingdom.

There is a project to build a third shipyard in the five-year plan, this year is the second year of the five-year plan, when the four new cities were selected last year, Su Yan took this matter into account, and finally the site of Licheng was decided, and the third shipyard of Xia Guo will be established in the Licheng area.

The city has a taller and wider wall than the standard city, and the shipyard in Li City, and the construction of the two cities is a little slower than the construction speed of the other two cities in the same period, which is still in the case of mobilizing more manpower, although the construction speed of the city and Li City is a little slower, but the city lords of the two cities have assured Su Yan that before the arrival of winter, the construction of the two cities will be completed.

If the construction cannot be completed, Su Yan will send more people over.

In the third month of spring and the first month of summer, eight children were born in the palace, five boys and three girls, Su Yan had one more son and one daughter, four grandsons and two granddaughters, Ping had two sons and one daughter, An also had two sons and one daughter, and Xia Guolong's family added eight more people.

I didn't feel anything before, only Su Yan would be embarrassed that her children and grandchildren were born at the same time, the same age, but now that her younger siblings were born with her son and daughter, Ping Hean finally felt the embarrassment on her father.

"Emma, my younger siblings are the same age as my son and daughter." Speechless, helpless, they have already been born, and they will get used to it after a period of embarrassment, and Ping Hean is still the first time to experience the feeling of being a father, and it is also the first time to experience the feeling of being an older brother.

The birth of eight children is only the first batch, and in the next year, there will be five more women in the palace to give birth, and now the palace is a little too busy, Su Yan can only find some women from the capital to enter the palace to help.

When the youngest child was full moon, Su Yan decided to hold a children's full moon wine in the palace and invited the high-level officials of the Xia Kingdom to participate.

In two months, Su Yan also got two other good news, among the tribes that were given an ultimatum by the Xia Kingdom, two tribes decided to join the Xia Kingdom, including the Liu tribe.

Before the arrival of autumn, there may be tribes who choose to join the Xia Kingdom, even if no tribe chooses to join the Xia Kingdom, the two tribes that have decided to join the Xia Kingdom now alone will be considered a profit for the Xia Kingdom, and the two tribes together have a population of nearly two thousand five hundred people.

In the second month of summer, in addition to these things, Su Yan also had a very important thing to do personally - the configuration of gunpowder.

Gunpowder can be used in war or production, for the powerful Xia Kingdom, the weapons and equipment of the Xia Kingdom has formed a generation gap with other tribes, occupying an absolute advantage, and there is no need to use gunpowder in war for the time being.

The use of gunpowder in production is different, open mountains and stones, open mines, build roads, these can use gunpowder, ignite gunpowder, explode, originally need to mobilize a lot of manpower and material resources to carry out the project, only need a bag of gunpowder to finish, very trouble-free, Su Yan put the configuration of gunpowder on the agenda early.

Configuring gunpowder is a dangerous thing, and it is easy to be dangerous to let a group of people who don't know the power of gunpowder to configure gunpowder, so it is necessary for Su Yan to do it personally, and wait for the gunpowder to be configured, so that everyone can understand the power of gunpowder and the process of configuring gunpowder, so that the possibility of dangerous situations will be reduced in the future.

It is to configure gunpowder rather than develop gunpowder, the formula of black powder is very simple, that is, one nitrate, two sulfon, three wood charcoal, three raw materials need to be prepared before the configuration of gunpowder, potassium nitrate, sulfur, charcoal.

Of the three raw materials, charcoal is the best to obtain, followed by sulfur, and finally potassium nitrate, especially potassium nitrate in large quantities, which is a very difficult thing, and Xia Guo has not found any trace of saltpeter ore at all.

Fortunately, obtaining potassium nitrate in small batches is no problem for Xia Guo.

The soil near animal pens and toilets often contains a large amount of organic matter, which decays and then acts by nitrifying bacteria to form nitric acid.

Nitric acid further reacts with arsenic, calcium, and magnesium in the soil to form potassium nitrate and its calcium, magnesium, and nitrate, which is soil nitrate.

The amount of potassium nitrate in various soil nitrates varies, generally a few percent.

Among the fluffy white mold precipitated on the walls of the animal pen and toilet, the potassium nitrate content was high, sometimes as high as 75 percent, so Su Yan directly ordered someone to collect it.

Prepare all three raw materials, but also to carry out a certain processing of raw materials, in order to carry out gunpowder configuration, this step is the most critical, but the final use of three raw materials for gunpowder configuration is the simplest thing, but the highest danger.
