In the second half of the seventh year of Jian'an, in the northern part of Bingzhou, west of Danhan Mountain and east of Yinshan Mountain, civil strife broke out in the tribal alliance of the Xianbei people.

At the beginning, Ye Zhao set a system for the tribal alliance, which was a wolf system, which strengthened itself by constantly plundering and robbing the resources of other grassland tribes.

But Xianbei perished, Kuitou, Kebineng, and Budugen died, and the remaining small tribes were divided up by the tribal alliance in the seven years of Jian'an.

Then the tribal alliance, which had no targets for plundering, finally turned the finger at its own people.

As for pointing the finger at the Han people, they didn't dare, first, Xu Rong guarded the state, and the army was strong, and secondly, they also needed to digest the looted population, cattle and sheep through the Han people's fang market, in exchange for survival resources, of course, some people saw the disadvantages of this strategy, and when the tribal alliance was almost fighting, they didn't even have the direction of looting.

It's just that Ye Zhao used two years to develop the habit of these people getting something for nothing, even if it was to quench their thirst, they were not willing to return to the bitter herding life of the past, so from Yanze to Yinshan, in the second half of the seventh year of Jian'an, they basically spent time in the war.

And for this kind of thing, under Ye Zhao's instructions, as long as it does not threaten the Han people, Xu Rong will not care, and will even secretly add fuel to the fire, which has led to more than forty tribes in the tribal alliance, and in half a year, it has been sharply reduced to six.

Correspondingly, Ye Zhao has 160,000 more women and children on his side, as well as as as 30,000 mine slaves.

In the winter of the seventh year of Jian'an, the melee that lasted for half a year came to an end, not that they didn't want to fight, but Xu Rong suddenly sent troops, and in the puzzled eyes of the only seven tribal leaders, he helped them put on shackles, and the only remaining more than 20,000 Xianbei men were sent to Zhangye and became mine slaves, and the rest of the population was sent to Bingzhou, Xiliang, and Guanzhong.

At this point, the huge Xianbei clan, under the dumbfounded attention of the princes of the world, was lost by Ye Zhaosheng's play.

At the same time, Ye Zhao sent 20,000 soldiers and horses in Zhangye, responsible for suppressing those mining slaves, and the price of drinking to quench their thirst was also revealed, these mining slaves, as long as Ye Zhao did not fall, in this life, they could only mine for Ye Zhao until they died of exhaustion in the pit.

It was also at this time that Zhangye's subordinate Guojuyan presented a surrender table to Ye Zhao, expressing his willingness to return.

This is the first subject country to take the initiative to surrender to the Han Dynasty and is willing to be unconditionally a vassal since Ban Dingyuan that year, and it also represents that Ye Zhao's control over the Western Regions has been further strengthened.

Although Juyan is only a country of one city, simply put, a country with only one city, Zhangye's unconditional surrender also represents that Ye Zhao's control over the Western Regions is gradually strengthening.

Ye Zhao ordered the king of Juyan to move his family to Chang'an, treat him as the marquis of the pavilion, and at the same time set Juyan as a county, which belonged to Zhangye County, and no longer had the title of Juyan's subject country.

In fact, it is not difficult to understand the attachment of King Juyan, the south is the Han Dynasty, the west is the western Xianbei, Ye Zhao destroyed only the central Xianbei, although the western Xianbei is not as strong as the central Xianbei, but there are more than 100,000 people, and there are as many as 50,000 people who control the strings, and they extort grain and grass wealth and women from Juyan every year.

Juyan has only one city, and the population is not more than 10,000 people, and even 10,000 households cannot reach it.

The Xiongnu were slaughtered, and the central Xianbei was also destroyed, and the western Xianbei, who had little to do with the Han Dynasty, did not want to provoke Ye Zhao, the evil star, so after Yinshan was occupied by the Han army and set up a walled city, the western Xianbei chose to move north without hesitation.

If you can't provoke the big Han, then the countries in the Western Regions around this area will be unlucky.

Juyan is sandwiched between the Western Xianbei and the Northern Xiongnu and the Han Dynasty, the Han Dynasty did not collect taxes from them, but the Western Xianbei and the Northern Xiongnu are different, every year the grain and cattle and sheep planted must be handed over to more than half, and a hundred Juyan beauties will be sacrificed to the Western Xianbei and the Northern Xiongnu.

Not to mention that Juyan can support a few years under such a high tax, only those Xianbei and Northern Huns come to fight the autumn wind from time to time, and last month, a head of Xianbei in the west even slept with the princess of King Juyan, and slept more than that, and then killed him cruelly.

No matter how bad a man is, it is difficult to endure this kind of thing, not to mention that no matter what King Juyan says, he is also the lord of a city, and after his anger rose, he directly ordered people to slaughter all the Xianbei and Huns in Juyan City that day.

The people of Juyan are naturally applauded by everyone, but the king of Juyan, who calmed down, knew very well that it was impossible for him to withstand the anger from Xianbei and the Northern Xiongnu in the west, so he simply declared himself a vassal to the Han Dynasty, and the city was gone, so he directly accepted all the conditions of Ye Zhao, gave up the ownership of Juyan City, and moved his family to Chang'an.

As for the western Xianbei and the Northern Xiongnu, now is the time when the energetic army in Guanzhong has nowhere to vent, if they really dare to come, Ye Zhao doesn't mind spending some time having fun with the Western Xianbei and the Northern Xiongnu, so he accepted Juyan's submission without hesitation, and directly ordered a few students who had just graduated from Chang'an Academy to go to Juyancheng to take over Juyancheng.

The new Ju Yanshou will be Zhao Tong, and he is also the eldest son of Zhao Yun, Zhao Yun was born before he defected to Ye Zhao, and later Zhao Yun voted for Ye Zhao, and the family followed Ye Zhao into Hanzhong, and later Chengdu/Du Academy was established, Zhao Tong also reached the age of study, and was sent to the academy by Zhao Yun.

And the Juyan County Commander, named Wang Ren, is a farmer's child, a specialized talent, and what he is best at is governance.

The two are about the same age, and they both want to do some performance, one wants to show their father, and the other wants to glorify the lintel, so as soon as they take office, they will actively co-ordinate, stabilize the people's hearts, train the army, and wait for a big job.

The Northern Xiongnu and the Western Xianbei did come, just when the two thought there would be a big battle, they were stunned to find that the Western Xianbei and the Northern Xiongnu chose to withdraw their troops when they saw the banner of the Han Dynasty at the head of Juyan City.

There were four or five thousand people on both sides, and they didn't release a single arrow, and they came violently, but they walked very simply, so that Zhao Tong and Wang Ren, who were already ready for a big battle, couldn't react, what are these people here for?

Although this battle made Wang Ren and Zhao Tong a little surprised, but for the people of Juyan, this is the first time to see the horror of the Han family's Tianwei, the Xianbei people and the Huns, who were extremely arrogant in the past, saw the Han family's royal banner, they didn't even dare to put a fart, and the most important thing is that Juyan City has now completely become a Han family city, and they will also be Han people in the future, and they don't have to live in fear as before.

Many people in Juyan did not have the slightest sorrow for the loss of the country, but were very grateful to the king of Juyan for offering the city and bringing them to the light.

And the initiative of the king of Juyan to surrender, is not just a city as simple, Rile, Delete Dan, Shichi, Wulan are all Zhangye rule, but in recent years, with the Han family's control of Zhangye continues to weaken, Dunhuang, Jiuquan, Zhangye's Shu land have been self-reliant, in name only, now seeing the reappearance of the prestige of the Han Dynasty, coupled with the leading role of the King of Juyan, one by one on the table of ministers, willing to sacrifice the city, return to the rule of the Han Dynasty.

These places used to be the territory of the Han family, and the people also had Han blood, and the culture was also evolved from the Han culture.

The initiative of a king of Juyan to join brought Zhang Ye seven or eight more cities from the previous commander of the light pole, these cities, as long as they are properly managed, are enough to feed Huaxiong's Western Regions Protectorate, and there is no need for Ye Zhao's side to spend a lot of manpower every year to transport grain and grass, which naturally made many officials under Ye Zhao's command who opposed the rebuilding of the Western Regions Protectorate Chi shut their mouths.

The lever car also came in handy because of Zhangye's stability, and the first to start using it on a large scale was not the army, but the traders who traveled to and from the Western Regions.

This kind of thing, can save a lot of horsepower, and the speed is not much worse than by horse consignment, after Ye Zhao released a hundred trial versions, they were bought out by the traders, and then a large number of caravans of the imperial court began to use this lever car to transport a large number of goods to the Western Regions, and at the same time brought back from the Western Regions to sell the local products of various countries to the states under Ye Zhao's rule.

In addition to poor stability, such as steering difficulties and lack of space, as more and more experimental data are sent and continuously improved, Shengongying has successively launched improved versions for sale to traders for trial.

To Ye Zhao's surprise, Ma Liang once designed something similar to a track to solve the problem of poor stability, but limited to the problem of today's materials, there is no solid enough material to make a large number of wooden rails, and wooden tracks can not be used for a long time, as for the use of iron, the cost is too expensive, and such a long distance, it is easy to lose, and finally this plan was knocked out, and then Ma Jun stuffed some cloth with some silk to wrap the wheels, in order to absorb shock, although the effect is not good, but there is always some effect, Later, Ma Jun suggested that Ye Zhao use cement to lay a cement road between Chang'an and Zhangye.

After all, the cement technology under Ye Zhao's rule is now mature, the cost is not high, and the labor is not troublesome, although it is easy to crack, but regular repair can be, as long as the road is spacious enough, once completed, even if there is no need to fly boat, it will not take a few days to travel from Chang'an to Zhangye, which has a great effect on Ye Zhao's control of the Western Regions.

After all, although the flying boat is convenient, there is always a risk, and the fuel required for a round trip is not a small amount, and in terms of versatility, it is definitely not as practical as laying a cement road.

In order to verify his idea, Ma Jun after getting Ye Zhao's nod, after leading people to pave the ground of the school field with cement, tried the lever car, the wheels wrapped in cloth were difficult and laborious to walk on the land, but on the cement road they walked like the wind, which also confirmed Ma Jun's idea, Ye Zhao also nodded and agreed, but this thousands of miles of cement road, it is not easy to repair it, Ye Zhao asked the Shengong Battalion to hire people, and at the same time ordered people to allocate funds to recruit people to build cement roads between the cities when the farm was slack. In this way, the transportation effect between the cities will be accelerated.

At the same time, the lever car, which had been improved several times, also began to be put into mass production, and the use of lever car was also included in a skill that the army under Ye Zhao must control.
