The topography of the Kazakh Khanate consisted mainly of hilly terrain in the north and plains in the west and south.

Such a flat terrain actually accelerated the advance of the Xia army, under the joint attack of the cavalry brigade of the sixth town and the Xianbeilian Protectorate, the Kazakh army was defeated and retreated, paying heavy casualties, and the Great Yuz Khan tried his best to resist, but his army was not funded by Tsarist Russia, and most of the army was still in a state of cold weapon combat, how could it face the Xia army with advanced rifles.

Under the fierce fire of the sixth town, the army of Dayyuz was almost immediately crushed, and in the midst of the artillery fire, the Kazakhs and soldiers of all ethnic groups in the army of Dayyuz screamed and fled in all directions, almost frightened.

In less than half a month, the Sixth Town defeated most of the troops that the Great Yuz Khan could muster, captured Almaty, the capital of the Great Yuz, and captured the Great Yuz Khan and his royal family members alive.

After the capture of the Great Yuz Khan, the survivors of Galdan and the Dzungar tribe who participated in the battle with the Sixth Town angrily pounced and punched and kicked the Great Yuz Khan.

With the elimination of Dayuz by the Xia army, the Khan of Zhongyuz, who had been plagued by the cavalry of the Xia army, finally felt the fear before the destruction, and he could only shrink his forces, intending to stick to Karayuda and the capital Astana, but the other ethnic groups living in the territory of the Kazakh Khanate were not ready to die with this rotten ship that was about to sink, and the Kipchak, Naiman, Kele, Argen and other tribes sent envoys to contact the Xia army, wanting to take the line of the Xia Dynasty and change a new master.

For these tribes who took the initiative to come to contact, Xia Jun showed a welcoming attitude towards them, and Mu Tianbo, the Duke of Qianguo, used the same set he had used in Yunnan on the heads of these tribes, and made these nomadic tribes choose to stand on the side of Xia Jun in the form of painting cakes.

Under Mu Tianbo's efforts, after the Xia army pacified Da Yuzi and continued its westward expedition, these tribes took the initiative to respond, providing guides and cavalry to the Xia army, and cooperating with the Xia army to attack Zhongyuzi.

After a fierce ideological struggle, the Khan decided to retreat westward, and joined forces with the Khan of the Lesser Yuz, and with his orders, the Kazakh army searched the city of Astana, and then embarked on the westward journey with a large amount of wealth and food.

In order to be able to save his life and everything he has, Zhongyuz Khan couldn't take care of his position as Khan, he chose to surrender to Xiaoyuz Khan, took the title of Khan, and respected Xiaoyuz Khan as the new Khan of the Kazakh Khanate.

Since then, the Kazakh Khanate, which had been divided for decades, has finally returned to unity, but this is only a stopgap measure, Xiaoyuz did not dominate within the khanate, his position as the khanate is still shaky, and without the threat of the Xia army, the civil war will definitely break out again.

However, the Xia army is menacing, and whether they have a chance to break out into a civil war again is another matter.

After the westward migration of Zhongyuzi, the Xia cavalry captured the city of Astana, the Xia cavalry held high the battle flag and entered the ancient city with their heads held high, the inhabitants of the city did not follow the westward migration, they looked at the foreign cavalry entering the city outside through the cracks in the doors and windows with frightened eyes, some men had already tightened their weapons, once these foreign invaders wanted to break into the door and hurt their families, they would fight back.

However, to their surprise, the army that called itself Xia did not intend to slaughter and plunder the city, and the Xia army began to impose martial law on the city after entering the city, imposing strict military control, and occupied the royal palace in Astana for the first time, but almost all the gold, silver and jewelry in the palace were looted, and when they entered the palace, it was already empty.

After the occupation of Astana, the Xia army did not rush to continue its westward advance, but imposed new rule in the occupied areas, pacified the people, and restored order.

The Xia army's military operations in the Kazakh Khanate soon spread, which made the Central Asian countries begin to worry, fearing that if the Xia army occupied Kazakhstan, the next one

step will not target them for expansion.

At this time, Central Asia was relatively stable, with two khanates south of the Kazakh Khanate, of which the Bukhara Khanate bordered the Ansib envoy of the Xia Dynasty, and the Khiva Khanate, located in the west of the Bukhara Khanate, bordering the Caspian Sea, and the two countries were in a state of hostility for a long time.

To the south of the two khanates, the once powerful Safavid Persian Empire (also known as the Safavid Empire) was on the verge of weakness and could not afford to heed the threat from the north.

In order to protect itself, the Bukhara Khanate took the initiative to send envoys to pay tribute to the Xia Dynasty, expressing its willingness to become a vassal state of the Xia Dynasty, but the Khiva Khanate was still waiting, and the Khiva Khan King Abkhaqi also secretly sent troops to fight with the Kazakhs in the name of mercenaries in order to prevent the Kazakhs from falling so quickly.

At the same time, he sent emissaries south to Isfahan, the capital of the Safavid Empire, hoping to persuade Shah Abbasid II of Persia to heed the threat from the north and provide assistance to the Kazakhs.

However, although Abbasid II had heard of the rise and expansion of the Eastern Empire, he did not seem to have feared that the Xia army would reach the Persian border, and he said this to the Khiva envoys:

"Since the Battle of Talas more than nine hundred years ago, the Chinese army has not appeared here, and it has not been since, and it is even less likely today, and the long distance will make the Chinese emperor discourage the idea of going to war with us."

Seeing that Abbasid II was so blindly optimistic, the Khiva envoy had no choice but to leave, but instead of returning directly to his country, he rerouted to the west to ask for help from the powerful Ottoman Empire.

When Abbasid II learned of the whereabouts of the Khiva envoys, he sneered disdainfully, and then put the matter behind him, looking at the cold and beautiful Persian dancers with a hedonistic smile on his face.

Time soon came to the thirteenth year of Wu'an, under the onslaught of the Xia army, the Kazakh army that moved to the west of Kazakhstan was still defeated, even if they were equipped with a large number of Russian-made weapons, but still could not defeat the experienced Xia army.

Amid the rumbling of gunfire, the Kazakh army abandoned their temporary capital, Aktobe, and fled to Atyrau, at the mouth of the lower Ural River, where they appealed to the Russian army on the other side of the river for help.

However, the Russian army did not receive an order from Moscow, and fearing that it would give the Xia army an excuse to cross the Ural River, so they ruthlessly chose to ignore it.

At the beginning of February of the thirteenth year of Wu'an, the Xia army was under the city of Atyrau, Mu Tianbo did not participate in the battle in person, and the first and second brigades of the sixth town in charge of the siege knew that the Russian army on the other side of the river was watching the battle, in order to show off their strength to the Russian army, but also to deter the other party.

The commander of the 1st Brigade then ordered all the artillery to be assembled and launched a heavy artillery bombardment on the walls of Atyrau, and in the deafening sound of artillery, the low walls of Atyrau fell one after another, and the Kazakh troops scattered in the city screaming or fell to their knees, praying loudly to the gods they believed in, hoping that the gods would appear to save them from fire and water.

But the gods were destined not to intervene in the bloodshed of the world, and it was not until the barrels of the artillery in the army were hot and could not continue to shoot that the brigade commander in charge finally ordered the shelling to stop.

At this time, the walls of Atyrau had collapsed in many places, and many buildings in the city were also affected by shelling, and the whole city was completely devastated, and the walls and streets were covered with dead bodies, like purgatory on earth.

Immediately, the commander of the 1st Brigade ordered the siege of the city, and the line infantry of the two brigades raised their rifles to the sound of the snare drums and advanced towards the city from many directions.

The Russian army on the other side of the Ural River has looked stupid, they are shocked by the artillery bombardment of the Xia army, although the Russian army also has artillery, but the use of artillery at this time has not yet lit up the tactics of "fire coverage", and there is no way to get the same results as the Xia Dynasty.

With the advance fire coverage of artillery, the resistance of the defenders in the city of Atyrau had fallen to the bottom, and after the Xia army slowly entered the city, only some fragmentary gunfire was heard, and finally in less than an hour, the Xia army took the city.

By the time the Xia army entered the buildings in the center of the city, the Kazakh Khan had already committed suicide, and the former Zhongyuz Khan took the rest of his warriors to the regiment

The Xia army, which had surrounded them, surrendered, and the Kazakh Khanate was destroyed.

As the news of the fall of the Kazakh Khanate spread, it immediately caused quite a stir in Central Asia and Eastern Europe.

When Tsar Alexei II of Russia heard about this, he bitterly said to his favored retainers: "The last barrier of the Kazakhs has been destroyed by the Xia, and from now on, we will face the threat of the Xiamen from the south to the north."

The Bukhara Khanate and the Khiva Khanate, after hearing the news of the fall of the Kazakh Khanate, reacted surprisingly unanimously, both fearing that the Xia army would attack south next, but the Bukhara Khanate was not so fearful, because they had already sent an envoy to submit to the Xia Dynasty, and the Xia army did not seem to have a precedent for a vassal state so far.

The Khiva Khanate was even more frightened, after all, they directly sent an army to help the Kazakhs fight the Xia army in another form, and its king hurriedly sent the prince south to Isfahan, repeatedly explaining the threat of the Xia army to Abbasid II, and asking to become a protectorate of Abbasid II.

Abbasid II saw that the prince of the Khiva Khanate had a snot and tears, and his attitude was sincere, and he also realized that things might be a little different from what he imagined, but he was still convinced that the Xia Dynasty would not continue to advance westward, so he agreed to the request of the Khiva Khanate and declared it a protectorate of the Khiva Khanate.

At the same time, the Persian army began to gather northward, and with the permission of the Khiva king, part of the Persian army moved into the border of the Khiva Khanate to guard against threats from the north, and part of it was deployed on the border with the Bukhara Khanate, which became worried.

The Khiva Khanate's actions to aid the Kazakhs and the military operations of the Safavid Empire did not escape the eyes of the Xia army, but Mu Tianbo, the Duke of Qianguo, was now focusing on digesting the occupied Kazakh Khanate and establishing an effective administrative structure in the Kazakh Khanate, so he was not prepared for war.

Moreover, the missions of Eastern European countries also arrived in the Kazakh region, and they were surprised that the Xia Dynasty's influence had expanded here, and expressed their intention to the local Xia army leaders, Mu Tianbo received them in a friendly manner, and divided a part of the army to escort the mission to the east.

When the war report from the west reached Jiangning City, it was already more than three months later, and the imperial court immediately began to organize celebrations for the great victory in the west, but some ministers, including Su Yan, were not only happy, but also discovered a huge hidden danger hidden under the good news.

That's the problem of inconvenient communication.

Today's Bactria is already a vast and huge empire, stretching from the Ural River in the west, Sakhalin Island in the winter, the Arctic Ocean in the north, and the Cham in the south, all of which are within the territory of Bactria and still do not count those overseas territories.

From the frontier fast horses gallop day and night, it takes at least two or three months to kill several fast horses to be able to send the news to the Beijing Division, and now it is okay, if a war breaks out in the border one day, or there is a rebellion, and the news is sent to the Beijing Division, I am afraid that the daylily will be cold.

In the absence of the will of the imperial court, the garrisons in various places can only act cheaply, if they meet the brave and responsible, it is fine, maybe they will solve the rebellion on their own before the imperial decree is issued, but if they encounter the kind of corpse vegetarian meal, then it will give the rebels a few months of development time in vain.

Unless a telegraph is developed that can communicate thousands of miles away, this problem is not solvable at present.

Moreover, Su Yan also knew that the current expansion speed was deformed, although he could expand rapidly with the help of the system, but after his death, without the constraints of the system, there was a high probability that there would be a rebellion in Central Asia and even further away, and it would still not be able to hold it.

For this reason, the Tang Dynasty's Imperial Protectorate system came in handy again, and the Imperial Protectorate established by the Tang Dynasty in the Western Regions has always played a role in maintaining the Tang Dynasty's ruling power here.

Su Yan was ready to set up a capital in Central Asia for a long period of rule, and even after his death, the strong military strength of the capital could still suppress the local resistance forces, and would not cause the Xia Dynasty's rule in Central Asia to collapse.

Therefore, he ordered the establishment of the Mengchi Protectorate on the territory of the Kazakh Khanate, with Astana as the residence of the Protectorate, and appointed Mu Tianbo, the Duke of Qianguo, as the first Protector of Mengchi

It is advisable to act with the right to use the Sixth Town as a long-term garrison of the Guardian of the Pond.

At the same time, considering that there were missions from European countries, he also ordered the establishment of a Xihonglu Temple in Astana dedicated to entertaining Western missions, so that Western missions would not have to travel to Jiangning City and waste a lot of time on the road.
