In the process of expansion, the Tatars accepted, and even deliberately captured aliens, but the Tatars also had restrictions on this, that is, these accepted people were all slaves and the ruled class, and naturally they would not regard these conquered people as part of the Tatars.

People don't play fusion, they play conquest!

In general, it is similar to the set played by the Mongols hundreds of years ago, their conquerors are high, and the conquered are all inferior, and these inferior people are divided into several classes, such as active cooperation, and can help some of the Tatar people to a certain extent, their status is naturally relatively high, and some of the groups that do not help, but there is no resistance, are average, and the fierce resistance of the group is the worst, and some groups will even be reduced to slaves because of fierce resistance.

This constitutes a hierarchical system of governance!

The advantage of this is obvious, that is, it is relatively simple to deal with, and it is easy and quick to establish effective rule in the conquered areas and use it for one's own use.

But the disadvantage is even more obvious, that is, the risk of rebellion is also very large, and even those who have been reduced to inferior people will not stop resisting for a moment.

In the end, the Mongol rule in the Central Plains only lasted for about a hundred years, and finally it was over, and for the past hundred years, the Mongols have been busy suppressing all kinds of rebellions, until a hundred years or so, it is really impossible to suppress it.

It can be said that the rule of the Mongols in the Central Plains has never been stable!

Therefore, after the Jurchens of later generations entered the customs, they were much smarter.

They learned the lessons of the Mongols, do not engage in too obvious oppression, although their own ethnic group still maintains a transcendent political status, but in the way of governance and culture, but take the initiative to move closer to China, and adopt a policy of butchering knives in one hand and carrots in the other, on the one hand, they take the initiative to ease the contradictions between the Chinese people, and carry out a series of livelihood policies such as heavy Confucianism, heavy use of Hanchen, and a series of livelihood policies such as the gentry paying food and errands, but on the other hand, they are raising a butcher's knife to play slaughtering the city, shaving their hair and making it easy to obey, At the same time, he has a lot of precautions against Hanchen.

In this way, the Chinese people can be enslaved for more than 200 years, and if the final stage is not for the great social changes in the world, the awakening of various isms, and the imperial system has been abandoned by history, maybe people can be enslaved for a few hundred more years.

The difference between the Mongols and the Jurchens in the Central Plains is huge, but they have caused great harm to the Chinese nation, and more seriously, the Mongols have caused relatively less damage, although they have killed countless of our clansmen, but that's it, they have not been able to cut off our blood and cultural heritage!

After a hundred years of fighting, the ancestors finally drove them away and let the Chinese nation rise again at the top of the world!

But although the ruling policy of the Jurchens is more relaxed, but their lethality is greater, they belong to the kind of people who kill without seeing blood, to put it mildly, even if the Qing Dynasty has been dead for more than a hundred years, but they still leave countless tumors on our culture, and the pigtail in the hearts of many people still cannot be cut off!

Qing palace opera can be a big fire, it is really the pain of the nation and the sorrow of China!

Wise and great, greater than the sun, the Holy Son of Heaven Li Xuan, who sprinkled rain and dew all known and unknown spaces, claimed to be a civilized modern person, but he could not do these disgusting things that the Mongols and Jurchens had done.

The Son of Heaven is merciful and great!

The Tang Empire under the rule of the Son of Heaven is also a ceremonial state of benevolence and filial piety, and the Celestial Empire!

Therefore, in the process of expansion, the Tang Empire is different from the expansion policies of the Tatars and Jurchens, and the Tang Empire, as a heavenly kingdom governed by benevolence and filial piety, will not do such bad things as leaving servility on other ethnic groups and destroying and distorting people's cultural traditions.

The Son of Heaven prefers to respect their cultural traditions and then erect a big tombstone for their cultural traditions!

There is a beginning and an end!

I don't want to talk about the advantages and disadvantages of the expansion policy of the Tang Empire and the expansion policy of the Tatars, but one thing is certain, that is, the Tatars' westward expedition provided a lot of nourishment for the Tatars, allowing them to develop rapidly, and to launch a larger-scale westward expedition.

When Li Xuan heard that the Tatars had won a huge victory in the western expedition this year, he was a little skeptical, whether these Tatars would fight to the Danube.

This is highly likely.

The military power of the Tatars, in fact, has always been not weak!

Although they were at a disadvantage in the confrontation with the Empire and were finally forced to withdraw from the Hetao and Fengzhou River regions, then again, in East Asia and even the whole of Asia, except for the Tang Empire, there were no other countries or tribes that could confront them.

With an army of more than 100,000 cavalry all over the mountains, it is not so easy to fight!

At least in today's Central Asia, if the Tatars had fought all the way to Western Asia, they would probably encounter a real enemy, well, the Ottoman Empire.

The Ottoman Empire is also relatively strong now, at least in the surrounding areas of the Eurasian border, they basically have no enemies that can pose a mortal threat to them.

Spain, known as the empire on which the sun never sets, now does not dare to run into the Mediterranean Sea and the Red Sea, it is the same at sea, as for fighting the Ottomans on land, not to mention, people can pile up the Spanish legions to death!

Otherwise, why there was the Age of Discovery, and the Western European countries wanted to find a route to the east, it was not because the Ottomans occupied the east and then monopolized the trade links in this region. And the Europeans couldn't do the Ottomans, so they had to find other routes to the east.

Therefore, without the Ottoman Empire, there would have been no Age of Discovery!

If the Tatars continue to expand westward, then they will definitely encounter the Ottomans, a strong enemy, and it will be interesting to see if the Tatars can outperform the Tatars at that time.

From the perspective of the Tang Empire, it is just right for the Tatars to help them test whether the road to the west is good or not, especially the strength of the Ottomans, so it is just right for the Tatars to give it a try.

After all, the strategic goal of the Tang Empire is to conquer the world, and this timetable is getting faster and faster.

At that time, Li Xuan's strategic plan was to develop science and technology in the early stage, restore people's livelihood, accumulate strength, and wait for the development of steamships and trains to mature and apply on a large scale, which is the time to kill the world.

Because at that time, distance will not be an obstacle to the Empire's conquest of distant lands!

Whether it is in the northwest or the northeast, or even to the South Seas or even the Americas, in fact, the biggest obstacle is not the local barbarian natives, with the strength of the Tang Army and Navy, it is enough to crush the resistance of any foreign race.

But the problem is that as an army that has entered modernization and entered the age of firearms, the Tang Dynasty army is becoming more and more dependent on logistics.

In the era of cold weapons, as long as the army can ensure that the military rations are sufficient, then it can maintain its combat effectiveness, and even the military rations can be eaten by the enemy.

But for the army of thermal weapons, not only military rations are needed, but also ammunition!

Moreover, the ammunition used by the Tang Army today relies heavily on the transportation of arsenals in the rear, and some of them have relatively high requirements for production and processing, and the simple ammunition manufacturing institutes set up by the military on the front line cannot produce them, and they must be produced in the professional factories of the three major weapons companies, such as howitzer shells and grenade shotguns.

These two shells belong to the type of flowering shells, but one is an explosion after landing, relying on shrapnel and shock wave to kill, and the other is an explosion on the top of the enemy's head, relying on the iron ball and shrapnel outside the projectile to kill the enemy.

The bodies and fuses of these shells are produced by high-precision processing equipment.

There are also some that can be produced by the soldiers themselves on the front line, such as ordinary solid shells, which are as simple as making an iron stove and pouring a round shell.

The bullets of the musket can also be made by the soldiers on the front line, although the current Tang Empire has been uniformly using paper shell bullets, combining propellant and lead bullet together, and making them into paper shell ammunition, which can greatly simplify the loading steps and increase the rate of fire.

However, the production process is relatively simple, these buckshot soldiers can be made directly from simple molds, and then loaded into paper shells with the propellant.

But this is at best just assembly, in fact, the propellant needed to assemble these bullets, and even the paper shells and lead blocks, need to be sent from the rear.

Therefore, in fact, there is no point in making bullets on the front line on its own, because all the raw materials need to be produced in the rear factories and sent to the front line, so it is better to complete the assembly of paper shell bullets directly in the factory, and then make standard paper shell bullets and send them to the front line.

And this, this is also the method adopted by the Tang Empire at present.

However, the military still retains a large number of improvised molds in the front-line troops, especially those for making lead bullets, so that in case their own ammunition supply is insufficient, they can also collect lead bullets and propellants on the spot and use them in combat.

But in any case, today's Datang army and navy still need some, and the army's dependence on logistics is very large, and the dependence on logistics is great, and it is difficult to carry out long-distance operations when transportation is not convenient.

This is also the reason why the Tang Empire is currently only maintaining a strategic defense in the northwest region, not that it can't be defeated, but that the supplies can't be sent!

However, all this will change with the advent of trains and railroads, and the Empire is already preparing to build a Northwest Railroad.
