After the demise of DTZ, the Tang Dynasty once again turned its attention to the domestic people's livelihood, paid attention to the people, and gave the people recuperation.

After the demise of DTZ, the prestige of the Tang Dynasty was in full swing, but the country's heritage did not improve much. What is the essence of the country? Population, cultivated land, and other craftsmen, skills, etc.

With a population, there will be enough soldiers, and only then will enough talents be born from it, only with arable land can they cultivate, and only then can the imperial court have taxes, and these are the essence of a feudal country.

With skilled craftsmen, they can provide a large number of high-quality weapons and agricultural tools to improve the combat power of soldiers and the level of agriculture.

Time flows, like flowing water.

The Tang Dynasty temporarily terminated the war and began to recuperate.

Wang Xuanji sat in Hexi, Hehuang, began to vigorously develop agriculture and animal husbandry, the land of Hexi, is the Central Plains Dynasty can be cultivated, can graze land, and this land is connected to the Western Regions in the west, the north controls Shuofang, the south curbs the plateau, and the east is Guanlong.

The status is very important, as long as it is a dynasty based in Chang'an Guanzhong, it must be valued here.

Once this place is lost, the enemy will be able to enter Longyou and threaten Guanzhong.

Wang Xuanjing took advantage of the drought to relocate the people of Guanzhong to the land of Hehuang, and after several years of operation, these Guanzhong victims have successfully taken root here.

At the same time, as the people of Guanzhong multiplied here, many of the Zahu who originally lived here were either expelled, killed, or surrendered.

Because of the abundant water sources in the land of Hehuang, Wang Xuanji led people to explore the landform, and then built a large number of water diversion channels to irrigate farmland.

If Hexi Hehuang is fully developed, it will not be a problem to feed millions of people, and now the total population of Hehuang and Hexi is only one million, and there are many Hu people among them.

If you want to firmly control the land of Hexi River, you must have at least two or three million Tang people here.

Because of the lack of population, Wang Xuanji began to use a large number of livestock here, because there was enough pasture, there were military horse farms, and there was no shortage of war horses, cattle, sheep and livestock.

Wang Xuanji vigorously promoted cattle ploughing and horse ploughing here, just to save manpower.

At the same time, a large number of water wheels were built in the irrigation system in various places, and even in some areas where water wheels could not be built, he also ordered people to build livestock to turn to carry water.

This water conservancy irrigation system has successfully covered millions of acres of farmland in the west of the Hehuang River.

With this water conservancy irrigation system, the farmland in Hehuang in Hexi has been harvested for four consecutive years. The tax of Zhenguan for eight years was enough to pay 2 million stone of grain, as well as a large number of cattle, horses, and livestock.

It is already more than a large state in the Central Plains.

The prosperity of Hehuang and Hexi made the Tang Dynasty very happy, after all, there was food in their hands and they were not panicked.

With food, a lot of things can be started.

And in front of him, there was one thing that Li Shimin couldn't help it.

Since becoming the Heavenly Khan, few of the Fanbang barbarians dared to disobey the orders of the Tang Emperor.

Over the years, although Xue Yantuo and Hui Hui have been a little dirty on the grassland, they are still very deferential to Datang and dare not take a step beyond Lei Chi.

But Tuyuhun, who felt that he was powerful, began to constantly test the bottom line of the Tang Dynasty.

Wang Xuanji's development in the west of the Hehuang River was very smooth, making it the base of the Central Plains Imperial Court to the west, and all kinds of money, grain, and war horses were rich.

Tuyuhun is one of them.

Tuyuhun was originally a Xianbei person, when under the blow of the great Qian, the Xianbei people have been living a miserable life, and later after the establishment of Liu Song, the Xianbei people lived a good life for a while, but they were soon hammered again.

With the decline of the Xianbei people, the Turkic people began to rise, and the Xianbei people could only migrate, some of them entered the Central Plains and merged into Zhuxia, the other part went west, integrated into the Western Regions, and some went to the west.

And Tuyuhun is a branch of the Xianbei people, and this Xianbei people have always maintained their independence, and they have also conquered some countries in the Western Regions, and their lives are not bad.

When it was the most powerful, it was west to Ruoqiang, north to Qilian Mountains and Hexi Corridor, south to Hehuang, east to Shuofang, and even the northwest of Bashu was controlled by it.

After the rise of the Tang Dynasty, Tuyuhun's sphere of influence began to shrink significantly.

Now Hexi and Shuofang have become the territory of the Tang Dynasty, and the same is true of Bashu, and most of the land of Hehuang has been occupied by the Tang Dynasty, and the scope of Tuyuhun has been reduced by more than half.

Originally, Tuyuhun was taken by the prestige of the Tang Dynasty to destroy the Turks, and he didn't dare to do anything, but later saw that the land of Hehuang and Hexi became richer and richer in the hands of the Tang Dynasty, but Tuyuhun himself was still poor, which made them want to snatch the land of Hehuang back more and more.

In the past few years, because the Tang army has not moved, and most of the handling of Fanbang affairs is to let Fanbang negotiate and settle it by itself, they only arbitrate, and even the army has not been dispatched once, which makes Tuyuhun have an illusion that Datang is just like this.

So he began to test the bottom line of the Tang Dynasty little by little.

The king of Tugu Hun first let some of these herdsmen pretend to be bandits, and the horse bandits invaded Liangzhou and Wuwei to rob cattle and sheep grain.

Then grab it and run, Wang Xuanji was unable to defend all areas because of the lack of troops in his hands, which allowed Tuyuhun to take some advantage.

After seeing that the Tang army was exhausted, the Tuyuhun Tuwang felt that the Tang Dynasty was nothing more than that, so he began to stop paying tribute to the Tang Dynasty.

After hearing the news, a fine light flashed in Li Shimin's eyes.

For Tuyuhun, Li Shimin has long wanted to clean him up. This tribe did not believe in its words, and rebelled during the Sui Dynasty.

The Sui army attacked, Tuyuhun could not resist, and began to surrender to the Sui Dynasty, and when the Sui army withdrew, Tuyuhun began to rebel again, and after a few times, the Sui Dynasty could not completely conquer Tuyuhun.

In the Tang Dynasty, after Tuyuhun was honest for a while, this kind of signs began to appear again.

Li Shimin has always wanted to find an opportunity to solve him, you must know that Hehuang and Hexi are important areas in the Tang Dynasty, and the side of the couch will not allow others to sleep soundly.

It's just that because of the defeat of DTZ, after the Tang Dynasty established a perfect tributary system, it was inconvenient to directly attack and destroy the small state of Fanbang.

Once he did this, everyone in the other small countries of Fanbang would be in danger, and the set of rules he had formulated would fall apart, so even if he wanted to destroy Tuyuhun, Li Shimin still endured it.

As a result, he didn't want to attack Tuyuhun, but Tuyuhun began to provoke Datang.

Li Shimin immediately issued an edict, ordering the king of Tugu Hun Tu to enter Beijing to pay tribute, and let him restrain his subordinates and compensate for the losses of the Tang Dynasty, but the king of Tugu Hun Tu did not take that edict seriously at all, directly refused the Tang envoy to pay tribute, and even blocked the road from Hexi to the Western Regions.

Li Shimin was immediately furious, and issued an edict to summon all the departments and states to send troops to jointly crusade against Tuyuhun.
