The day after the victory in the Battle of Taku, the town of Taku finally ushered in reinforcements, and it was none other than Li You who brought people here.

And this is also the first time Li Cao has seen his uncle since he stepped on the Northwest Battlefield.

Looking at his uncle, who was not a few years older than himself, but exuded iron and majesty, Li Cao didn't know what to say for a while.

In this way, the uncle and nephew who met on the battlefield have not said a word since they met, and they have not said a word until now, and they just look at each other like this.

"Girl, this battlefield really shouldn't let women set foot in, and I have always believed in it, even if our family has had a female general who has made great achievements in the past, Princess Pingyang, but then I also think it's just a special case, but now that I see you, I think I'm wrong, women can really become generals who command thousands of armies, so from today on, you will follow me, now give you a day, hand over all defenses, bring your soldiers, follow this general, and clear the remnants scattered in this northwest land, Let the forces in this land threaten my Tang rule in impotence"

In the end, it was Li You who broke the silence, he first gave Li Cao his affirmation, and at the same time gave Li Cao an order.

After saying this, Li You got up directly and left Li Cao's residence to deal with various military affairs.

And Li Cao didn't say a word during Li You's speech, and listened carefully there, until his fifth uncle left, Li Cao's face showed a smile, the kind of smile that was recognized and affirmed.

But this joy did not last long, and from the moment she stepped out of her residence, to hand over the defense, and to mobilize the soldiers, she regained her characteristic cold sharpness.

When Li Cao handed over everything, early the next morning, Li Cao set off with his own Baifengwei with Li You's army.

At this time, Li Cao knew that when his fifth uncle arrived in Taku, the Western Turkic army in Helin gave up the assault on the fortress of Helin and turned to the north and scattered on the northern grasslands.

And Li You's task is to exterminate this force.

And for this goal, Li Cao followed Li You, in this vast northwest land, attacked everywhere, fought hundreds of battles large and small, and finally lasted a year, and finally controlled all the places of the entire former Western Turks in Zhenguan 13, and opened up millions of territories for the Tang Dynasty.

And Li You also relied on this merit to be named the king of martial arts by Li Shimin, Xue Rengui also changed from the Marquis of Baihu to the Duke of Pingguo, and Wang Xuance and Su Dingfang were also awarded the title of Marquis.

Even Li Cao was named a princess, and the title directly inherited the title of Princess Pingyang, and was named Princess Pingyang Zhao.

And Li Cao's Baifengwei has also reached 20,000 after many additions and expansions.

With the fall of the Western Turks and the northward flight of Goguryeo in the northeast, the territory of the Tang Dynasty was infinitely expanded.

But obviously this could not satisfy the ambitions of Li Shimin's father and son, after thoroughly consolidating the two battlefields, considering the future situation, Su Dingfang was transferred to the northeast, replaced Li Jing's position, continued to organize troops, and pursued the Goguryeo people who fled north to the north.

Li You and Li Cao each led their own armies, from the northwest border to the north, deep into the grassland, and the White Tiger Guard, who had already assembled on the former Eastern Turkic border, to the depths of the grassland.

Li Xiaogong went to the newly established Xizhou Prefecture, the former Western Turkic place, to take over Xue Rengui's position to guard the frontier, and Xue Rengui and Wang Xuance returned to Chang'an to report on their work.

In Goguryeo, Li Jing and others, in addition to leaving Chai Shao and Hou Junji to guard and govern the newly established Northeast Road, so the general returned to Chang'an to report on his work.

After this transfer, except for the two armies of the Northern Expedition, the rest of the Tang Dynasty has entered the road of peaceful development.

With the efforts of Li Shimin and a group of civil servants, the newly laid land in various places has slowly regained its prosperity, and countless conquered alien races have gradually integrated into the Tang Dynasty under various policies, and three years have passed.

In the past three years, in addition to various developments, a lot of things have happened in Datang.

The first is Li Yuan, who should have died in the ninth year of Zhenguan, and finally died of illness in Guanghua Palace in September of the 14th year of Zhenguan after living for five more years, and was buried with Empress Taimu Dou in Yu Xianling 7 days later.

And there is a funeral and there is a happy event, after guarding the tomb for Li Yuan for half a year, Li Chengqian held a wedding for his eldest daughter Li Yun and Wang Xuance, the lord of Yiyang County, in the fifteenth year of Zhenguan.

This wedding, the scene is no less than the wedding of the eldest princess Li Wei.

After Li Yun got married, Li Chengqian's sister Li Li Li and Li Man also married Yu Chi Baolin and Changsun Chong one after another.

With the efforts of the Ministry of Education in recent years, the entire Datang has built as many as 2,000 colleges at all levels, and has trained more than 200,000 students, of which nearly 5,000 have successfully graduated and entered the yamen in various places, which has greatly reduced the demand for officials in Datang.

After the education is finished, that is the people's livelihood, and when it comes to the people's livelihood, we have to mention the establishment of the Royal Bank, led by the crown prince and headed by the eldest princess Li Wei.

Once the Royal Bank was established, it made the original complicated off-site transactions extremely simple, and all merchants only needed to deposit their money in the Royal Bank in one place, and then take the deposit certificate issued by the bank, they could go to any place in Datang where there was a branch of the Royal Bank, and withdraw their money.

This reduces the hassle of carrying large amounts of money for off-site transactions.

It is also because of the opening of the Royal Bank that it has driven the trade of the entire Datang, and has also created countless job opportunities, so that hundreds of people have benefited.

So in the second year of the establishment of the Royal Bank, that is, in the sixteenth year of Zhenguan, under the proposal of the crown prince Li Chengqian, with the support of all the ministers, Li Shimin directly made a decision to reorganize the Eagle Guard, and the original Eagle Guard plus the officials of the Yamen in various places, and the City Defense Department formed a new department, the Ministry of Police, with Li Tai, the king of Qin, as the minister, to lead all the police in the Tang Dynasty, strengthen public security in all parts of the Tang Dynasty, and crack down on all kinds of crimes.

Although the establishment of these departments has caused tremendous changes among the people, it is not these that really make Li Shimin happy, but the letters sent by his third son from time to time.

Ever since Li Ke went to the south, Li Shimin has been concerned about the development of this situation.

At first, when Li Ke won the entire Nanzhao Kingdom, Li Shimin didn't feel anything, but with Li Ke's continuous conquest, in just three years, the current Li Ke has already laid, and the land area when Li Tang was first established.

This made Li Shimin run to his father's grave alone when he got the news, and stayed for a whole night, during which no one knew what this generation of emperors said, only that when Li Shimin left, his eyes were red.
