The efforts of the Withered Grass Tribe have had some results, and in half a month, three tribes, including the Goshawk Tribe, were inclined to unite with the Withered Grass Tribe or were in a state of hesitation.

Immediately, the leader of the withered grass sent three teams to send invitations to the three tribes, and the four tribes sent people to discuss the matter of uniting against the black tribe, if the alliance can be formed, the leader of the withered grass is sure to attract more nomadic tribes to join the alliance.

Five days later, the leader of the Withered Grass tribe personally went out, and the other three tribes did not have a leader in person, but sent one or two high-ranking tribesmen of the tribe, and the people of the four tribes met in a place far away from the Withgrass tribe to discuss in detail the matter of the union of the four tribes.

There are very few tribes in the savannah where the jungle is the jungle in alliances, and the most fundamental reason is the distrust between the tribes, fearing that the strong will eat the weak.

The Withered Grass Boss has set several rules for the Alliance in response to these issues:

First, the alliance was formed to fight against the Black Tribe, and if the Black Tribes were destroyed, the alliance was dissolved.

Article 2: Members of the alliance shall not inquire into or search for the location of the other tribe's residence.

Article 3: The affairs of the alliance shall be discussed by the leaders of the member tribes together, and finally voted by a show of hands, and the majority of the people agree to pass it.

……

One rule after another was determined, coupled with the threat of the black tribe, nine days later, the leaders of the four tribes gathered together, blood alliance, the anti-black alliance was officially established, and there are currently only four members of the withered grass tribe and the goshawk tribe.

After the establishment of the Anti-Black Alliance, the leader of the Dead Grass immediately launched the first proposal of the Alliance, inviting more nomadic tribes to join the Anti-Black Alliance in order to fight and even destroy the Black Tribe.

As soon as this proposal was put forward, it was approved by all the leaders, and now there are four member tribes of the Anti-Black Alliance, and the combined population of the four member tribes is less than 9,000 people, and the number of adult tribes is 3,000, and the maximum number of adult tribesmen who can participate in the battle at the same time will not exceed 2,700, and if only adult male tribesmen are counted, this number will be halved.

Think about the situation where the Black Tribe lives, think about the powerful cavalry force of the Black Tribe, and think about the Black Tribe's long-range and powerful bow and arrow, even if the four tribes gather a total of 2,700 adult tribesmen to besiege the Black Tribe, the war is won, the Black Tribe is destroyed, and the four tribes will suffer heavy losses.

Not to mention that the four tribes will not send out all the adult clansmen of their tribe who can participate in the battle, once they are all sent out, and the tribe will suddenly encounter people from other tribes in their settlements, then the tribe will be in danger.

In order to protect the tribe, each tribe can send out more than half of the fighters of their respective tribes.

And if you want to fight against the black tribe or even destroy the black tribe, and the losses of each tribe will not be very large after the war, then the anti-black alliance needs more than ten members, and only more than ten nomadic tribes will unite to attack the black tribe together, and then the black tribe can be destroyed at a relatively small cost.

This time it was no longer the Withergrass tribe acting on its own, taking advantage of the fact that winter had not yet arrived, the four existing member tribes of the Anti-Black Alliance had sent several teams to look for other tribes in the area around the tribe's residence, and invited them to join the Anti-Black Alliance to fight against the Black Tribe together.

Regardless of whether the other party agrees or not, let the matter go first, and then send out an invitation, winter is coming, and we can continue to discuss it next spring.

Especially the withered grass tribe, before the withered grass tribe sent five teams to contact other tribes, to tell those tribes about the black tribe, the most worried is that these tribes will move to a distant place next spring, while the winter has not yet come, first tell them about the establishment of the anti-black alliance, maybe you can attract a few nomadic tribes to join the anti-black alliance, increase the strength of the anti-black alliance.

Anyway, the establishment of the Anti-Black Alliance is only to deal with the Black Tribe, and after the Black Tribe is destroyed, then we will discuss whether the Anti-Black Alliance will be disbanded or continue to exist.

……

Winter has arrived, while the weather is not too cold, Su Yan sat on the warm fire, with the faint oil light, to deal with the major events of the Xia Kingdom, the main thing is to set the plans for next year.

One of the most important things in the Xia Kingdom this year is the war against the Japanese tribal camp and the fishing tribe, the Xia country wiped out the Japanese tribal camp and the fishing tribe at a very small cost, only about a thousand people in the Japanese tribal camp were escaped, and the fishing tribe was more numerous.

The Xia expeditionary corps killed more than 5,000 enemies, and also captured a large number of people, nearly 11,000 prisoners from the Japanese tribe camp, and 12,000 prisoners from the fishing tribe, fortunately, the conquest of the Japanese tribe camp and the fishing tribe was carried out in spring and summer respectively, and when the captives of the fishing tribe were transported back to the cities of the Xia country, the captives from the Japanese tribe camp were almost digested.

In addition, the cavalry troops penetrated into the steppe four times, destroying a total of four nomadic tribes, and obtaining a large number of cattle, horses and sheep, as well as more than 5,500 prisoners.

The expeditionary corps and the cavalry troops actually increased the population of the Xia Kingdom by nearly 30,000 in one year, and don't forget, there are also the population obtained by the three tribes that were destroyed when preparing for the construction of the southeast and southwest cities of Zhongjing, basically this year, the Xia Kingdom gained a population of 30,000 through foreign conquests.

Fortunately, the total population of Xia Kingdom is already more than 230,000 people, and there is no problem in digesting 30,000 people.

With the collapse of the Japanese tribe camp and the fishing tribe, there were no other tribes living in the area on both sides of the main trunk of the Yellow River from Yancheng to the fishing tribe, and those tribes who originally lived in this area either joined the Xia State or were destroyed by the Xia State, and a few tribes were forced to move away from the Yellow River.

The war against the Japanese tribal camp and the fishing tribe was over, and for the next year or two, there would hardly be a war to send out expeditionary legions.

With the addition of 30,000 captives, the total population of Xia has exceeded 260,000, which is still a relatively small number, Xia can obtain a large number of people through foreign wars, but there is no opportunity to send expeditionary legions in the next one or two years, mainly because other tribes that have determined the information are too far away from Xia State, and it is not worth it for Xia to use a lot of manpower and material resources to spend a lot of time to conquer distant tribes.

Of course, if the travel time can be shortened, it is also possible to continue to allow the expeditionary corps to continue to fight abroad.

In the summer of this year, the Licheng shipyard built a new ship, and Su Yan personally went to Licheng to witness the launch of the new ship.

After a month of sea trials, it was almost certain that the new ship had been successfully built and had reached the capacity of the design, and Su Yan named the new ship as a C-type ship.

Type A boats, Type B boats, Type C boats, and now Xia Guo already has three types of ships.

The A-type boat, six zhang long and one and a half zhang wide, can carry more than ten tons of cargo at a time, and can carry about 100 adults at a time.

There are three versions of the A-boat, which are the ordinary version of the A-boat, the improved version of the A-boat, and the slightly modified A-boat.

The ordinary version of the A-type ship has been discontinued, and the newly built A-type ship will be an improved version of the A-type ship, and the slightly modified A-type ship is the ordinary version of the A-type ship that has been put into use.

Of course, the slightly revised A-boat is not as fast as the improved version.

Among Xia Guo's A-boats, the number of ordinary A-type ships is already less than ten, and all the remaining A-boats will be modified in about next year.

Class B ship, eight zhang long and two zhang wide, can carry 30 tons of cargo at a time.

There are two versions of the B-type ship, namely the ordinary version of the B-type ship and the slightly modified B-type ship, the slightly modified B-type ship and the slightly modified A-type ship is a reason, because the number of B-type ships is only fifteen, all of which have been slightly revised, and the newly built B-type ships are also slightly revised.

Su Yan received a report from the Zhoucheng Shipyard, which had spent many years researching and improving the B-type ship, and would soon build a new version of the B-type ship, which would have a faster speed than the slightly modified B-type ship or even the improved A-type ship.

Finally, there is the C-type ship, which is seven and a half feet long and one foot six feet wide, and can carry 20 tons of cargo at a time.

The carrying capacity of the C-type ship is more than that of the A-type ship and less than the B-type boat, which is in the middle position, but the deadweight is not the main design feature of the C-type boat, and the most important feature of the C-type boat is its speed, which is faster than the fastest improved version of the A-boat.

Suppose a river section, under the same wind speed, the ordinary version of the A-type boat takes ten days to complete, then the slightly modified version of the A-type boat takes nine days (about 9 days), the improved version of the A-type boat takes seven days, the ordinary version of the B-type boat takes eight days, the slightly modified version of the B-type boat takes seven and a half days, but the first version of the C-type boat only takes five and a half days, and the speed of the C-type boat is twice as fast as that of the ordinary version of the A-boat.

Sailing on the Yellow River with a C-type boat will make it faster for the Xia Kingdom to connect with the three cities in the Chucheng area, and it will also save a lot of time to communicate with the tribes of the new route.

After the situation of the C-type ship is determined, the Licheng Shipyard will make every effort to build the C-type ship, if the situation allows, Su Yan will also let the Zhoucheng Shipyard and the Yuancheng Shipyard also build the C-type ship, and now the Xia Kingdom lacks ships, and there is also a lack of ships with fast speed.

In the next few years, the Xia Kingdom will need more C-type ships, on the one hand, to reduce the time spent on exchanges between the various cities of the Xia Kingdom, and on the other hand, to carry the expeditionary corps to march farther and gain more population for the Xia Kingdom through war.

However, this matter cannot be rushed, after all, the C-type ship has just been built as a prototype ship, and the shipbuilders can still make a little improvement to the C-type ship, and then it will be built in large quantities.

Su Yan thought about it, the expeditionary army is unable to wage war against distant tribes, but it does not mean that there is no war to fight, if it is far away, then come closer, it just so happens that the Xia Kingdom is about to start building cities in areas far away from the river, and there are still some tribes living in areas far away from the river.

"Take two adjacent cities as a unit, and each city mobilizes one team of field/battle army and one team of city defense army, a total of four teams and more than 360 people.

With the two cities as the center, the city on the south bank of the Yellow River explores to the south, and the area on the north bank of the Yellow River explores to the north, and each team explores the terrain and products while looking for other tribes.

If the tribe is weak, attack directly, and if it is strong, retreat first and mobilize enough men to come over. ”

Su Yan wrote down the new plan, and perfected it in the winter, which could be regarded as preparing for the Xia Kingdom to build a city far away from the river.

The cavalry troops still went deep into the steppe once every two months according to the plan, but there were some problems on the side of the city.

The walls of the city are the tallest of the standard cities, but the maximum population of the city is 10,000, just like other standard cities, and the number of inhabitants in the city is almost there.

In response to the problems faced by the city, Su Yan has two solutions:

The first is to expand the storage city, which has an expansion plan when it is designed and built, and the scale of the storage city can be expanded according to the expansion plan;

The second is a plan to build a new city in the grassland area.

Both options have a number of problems.

In the first plan, after the expansion of the city, because the city is located in the edge of the grassland, it may encounter the attack of nomadic tribes, and the expanded city still needs a tall city wall, and the amount of work is much larger than the existing city wall of the city.

The second plan is the selection of the site of the new city, the scale of the new city can be the same as the storage of the city, but the location of the new city is an important issue, such as the storage of the city, the west is the grassland, the east is the jungle, the south is the Yellow River, a very good area.

It is best to build a new city in an area similar to that of the city, but this kind of area will not be able to find a second one for a short time, and it will not be close to the city.

The new city must not be built along the Yellow River, and the inhabitants of the city need to burn a lot of firewood and grass every day, even if they have coal, and the new city must be close to the jungle.

Thinking about it this way, the new city can be built in the north of the city, it doesn't matter if it is not close to the Yellow River, the Xia country already has enough horses, and the new city is still on the edge of the grassland, and you can ride horses and drive carriages to and from the city quickly.

Both plans can be carried out, and in the end, Su Yan plans to carry out the first plan to expand the city, after all, the city has enough population, even if there is an enemy attack, the city can repel the enemy, and instead build a new city, it is necessary to mobilize more people to prevent an enemy from attacking.

The first plan is to expand the city, and after the first plan is over, the second plan can be carried out, and in the future, the city will be the center of the western region of the Xia Kingdom, and it can be named "Xijing".

In this era of backward communication conditions, when the territory of the Xia Kingdom reaches a certain scale, five capitals can be set up at that time, with the Central Capital City as the center, and the four accompanying capitals are located in the four directions of the Central Capital City, and the five capitals are responsible for the affairs of the Xia Kingdom.

During the night, Su Yan had a dream in which the Xia Kingdom already had millions of people under Su Yan's own rule, and its territory was vast, and there was no enemy who was the opponent of the Xia Kingdom......

[It's just a dream, this book is not over, there is still a lot to write]
