The video connects all dynasties, starting with an inventory of the top ten emperors

While watching the video, Li Shimin asked someone to bring all the documents related to Tubo, and studied them carefully.

Songtsan Gampo ascended the throne in the third year of Zhenguan (629 A.D.). Around the seventh year of Zhenguan, he unified the Tibetan tribes on the plateau and established a state system in Luoxie (Lhasa).

According to the documents, Songtsen Gampo’s previous Tibetan Zanpu had no records, and he was most likely the first Zanpu with records in Tibetan history.

In the eighth year of Zhenguan, Songtsen Gampo sent envoys to the imperial court, and the imperial court also sent envoys to pay a return visit to Songtsen Gampo.

In the 12th year of Zhenguan, after Songtsan Gampo's marriage proposal to Datang was rejected, he led his troops to plunder the people and livestock south of Qinghai in Tuyuhun, and annexed Dangxiang and Bailan Qiang.

Later, the Tubo army approached Songzhou of the Tang Dynasty and attacked the sentry team of Han Wei, the governor of Songzhou.

The imperial court then sent Hou Junji and others to lead [-] troops to attack Tubo. Niu Jinda, the vanguard general, defeated Tubo at the city of Songzhou and beheaded a thousand.

Songtsan Gampo then withdrew his troops, and the Battle of Songzhou ended with Tubo's voluntary withdrawal of troops. After the war, Songtsan Gampo withdrew from the old land of Tuyuhun, sent envoys to plead guilty, and proposed marriage to the court again.

"It's really a wolf's ambition!"

After comparing the maps, Li Shimin discovered that the battle between the Tang Dynasty and Tubo in Longyou was the old land of Tuyuhun.

In other words, after Tubo withdrew from the old land of Tuyuhun two years ago, it did not know when it annexed Tuyuhun again.

"Tubo has repeatedly acted like this. He really doesn't know what is good and what is bad. He should send a large army to attack him!"

While studying the geography of Tuyuhun's old land, he analyzed and resolved Tubo's strategy for future generations.

It can be seen from the video that at this time Tubo has threatened the Tang army from Longyou, Hexi, Anxi and other places. If you want to curb Tubo's invasion, you must send elite soldiers to guard the important places.

When Li Shimin learned about these three geographical locations, the video continued to show the new achievements in the theater.

[Hexi Theater.

In the winter of the 14th year of Kaiyuan (726 A.D.), Tubo broke Guazhou (Jiuquan, Gansu), surrounded Changle County and Ganzhou (Zhangye, Gansu), and burned and plundered everywhere!

Hexi Jiedu envoy Wang Junxi (chan) and Changle county magistrate Jia Shishun defended the city without losing it. Wang Junxi sent people into the territory of Tubo by small roads and burned the weeds beside the road. Half of the Tubo horses died without food.

Wang Junxi and Zhang Jingshun attacked the rear army of Tubo in the west of Qinghai, and obtained tens of thousands of Tubo's supplies, sheep and horses.

In the 15th year of Kaiyuan, the Hexi Jiedu envoy Wang Junxi was attacked by Huihe Hanhai Sima Hushu. Wang Junxi and his subordinates fought hard and died. He and Long shook!

In the same year, Xiao Song succeeded Hexi Jiedu. He used countermeasures to get rid of the Tubo general Xin Nuoluo Gonglu, appointed Zhang Shougui, Du Binke and others to defeat Tubo in a row, and the situation in Hexi gradually stabilized.

In the 17th year of Kaiyuan, Zhang Shougui, the governor of Guazhou, and Jia Shishun, the governor of Shazhou, attacked the Datong army of Tubo, killing and invincible. 】

"It seems that the Western tribes are still rebellious. A small Hanhai Sima dared to attack the majestic Hexi Jiedushi. This is simply a provocation to the Tang Dynasty!"

After thinking about it again and again, Li Shimin still felt that Tubo's capture of the old land of Tuyuhun was the biggest dereliction of duty of the guards and princes of the Tang Dynasty at that time.

In the so-called Longyou war zone, Tang Jun and Tubo fought back and forth, and the fight was still the old land of Tuyuhun!
Brother Shu Han of the Tang Army also occupied the land of Jiuqu, so he kept the key to Longyou, and Longyou has settled down since then.

Even if you don't talk about the geography of the former land of Yuhun, if you only talk about Tuyuhun as a vassal state of the Tang Dynasty, Tubo cannot annex Tuyuhun.

How could the court princes of later generations sit back and watch Tubo seize the old land of Tuyuhun!

In the past, Tubo occupied the old land of Tuyuhun, but the Tang army could not help the subordinate country to maintain justice; later, Hanhai Sima attacked the Hexi Jiedushi, and it seems that the Tang army did not show any color, so what majesty does the Tang Dynasty have to say!

Through a series of battles, Li Shimin gradually realized that the Tang army of later generations lost the most important thing, that is, prestige.

The tribes on all sides of China have always been disobedient, that is to say, the Tang Dynasty punished them repeatedly, which made the Tang army's mighty.

If a tribe violated the Tang army without being punished, it would inevitably cause unrest in the hearts of the people in the long run.

This should be a direct reason why the Fan tribe dared to attack Wang Junxi. When Tang Jun encountered such provocations, he acted like a thunderous soldier and completely wiped out Hushu and his followers.

If the children and grandchildren of later generations are not punished for all rebellions, they will not be able to deter Xiaoxiao, and the combination of grace and power will become empty talk.

Only then did he understand the purpose of the declarations at the beginning of the video.

These declarations, accompanied by iron and blood, are the order maintained by successive dynasties regardless of cost.

During the Han Dynasty, "movement will destroy the country" and "those who violate the strong Han will be punished even if they are far away", which represent the majesty and inviolability of the Han army!
And his Tang Dynasty can also say, "If you don't accept it, you will be sent out to attack Erguo next year"!
East Turkic Jieli Khan once entered the bandits at the beginning of Zhenguan and drank the Mawei River; in the third year of Zhenguan, Li Jing and Li Jibei attacked Eastern Turkic, destroyed its country, and captured its master Jieli Khan.

Since Tuyuhun invaded the front line of Yongliang during the reign of Wude (Li Yuan), it has frequently invaded the border areas; The Tang Dynasty was established.

Ju Wentai, the lord of Gaochang Kingdom, has repeatedly intercepted the envoys from countries in the Western Regions to go to the Tang Kingdom, and refused to listen to the advice of the Tang court;

After these three battles, the Great Tang became famous in Mobei and West!
The flag of the Tang Dynasty itself should have the function of deterring Xiaoxiao, and the court must strictly deal with such principled issues as Hu Bu's killing of the guards of the Tang Dynasty and intercepting the envoys.

Issues of principle must never be compromised. Once a compromise is made, future double-minded people will continue to wait for opportunities to rebel.

"It seems that this kind of foreign strategy must become the national policy of my Tang Dynasty, and it will remain unchanged forever!"

In the third year of Emperor Wu of the Han Dynasty (102 BC), Weiyang Palace in Chang'an.

Watching the Tang army and the Tubo army fighting on the front line of the Hexi Corridor, Liu Che thought of his hussar general.

In the second year of Yuanshou (121 BC), General Huo Qubing attacked Hexi twice, captured more than 4 heads of the Xiongnu, and forced King Hunxie to surrender with [-] troops. The Han family had all the land in Hexi.

This is also the first time that the Han Dynasty occupied the Hexi Corridor, opened up the road of communication with the Western Regions, and completely separated the Qiang people from the Huns.

Thinking about it, he thought of Li Guangli who was staying outside Yumen Pass at the moment, and compared the two sides, he couldn't help sighing: "At that time, Huo Huoqi was only 19 years old... Li Guangli, a mediocre talent, is really useless!"

"Just in time, I also want to see how the later dynasties guard the Western Regions and even Dawan and other countries west of Congling."

[Anxi (Western Regions, present-day Xinjiang and Central Asia) theater.

In the second year of Kaiyuan (714 A.D.), Qixi Jiedushi Ashinaxian led his troops to quell the rebellion in Dutan, and collected 3 tents from the tribes west of Suiye.

Ying Zheng: "Ashi Naxian, do I have such a surname in China?"

Liu Che: "Broken Leaf?"

Liu Da (Eastern Han Zhangdi, da): "Where are the broken leaves?"

In the third year of Kaiyuan, Guo Qianguan, the protector of Beiting, defeated the invasion of Tujue Mochuo and Tubo, and offered to capture Chang'an.

Yang Guang: "Turks really rebelled like the words of the gods. It seems that this Great Tang is very close to my Great Sui!"

Li Shimin: "The Turks also rebelled?!"

In the third year of Kaiyuan, Tubo and Dashi (Arabs) attacked the country of Bahana (Dawan in the Western Han Dynasty) and set up a false ruler;

At the request of the ruler of the country, Zhang Xiaosong, the supervisory censor, assembled more than [-] Han troops and tribal soldiers from the surrounding areas, and traveled thousands of miles west of Kucha (now Kuqa, Xinjiang) to defeat the false ruler in Liancheng, and captured and beheaded thousands of people.

At the same time, Qixi Jiedu envoy Ashina Xian successively recovered Shi, Cao, Kang and other countries, cleared Dashi and Tubo's influence in Bahana, and Tubo retreated to the south of Congling.

Liu Che: "Tang Jun is strong, Li Guangli is really incompetent!"

Liu Da: "Now that General Geng is stationed alone in the Western Regions, I don't know what's going on."

Li Shimin: "Hahaha, Zhang Xiaosong did a good job, maintaining the majesty of the Tang Dynasty."

In the fifth year of Kaiyuan, Tang Ting thwarted the conspiracy of Tuqishi and Tubo to invade the four towns of Anxi.

In the eighth year of Kaiyuan, the Tang court rewarded the first-line kings in the south of Congling, and set up the Jimi Army Mansion.

In the tenth year of Kaiyuan, Beiting Jiedu envoy Zhang Xiaosong sent deputy envoy Zhang Sili to lead Fan and Han soldiers with four thousand soldiers to support Bolu, a small country, to relieve thirst and pantuo, and set up Congling to guard.

In this battle, the two armies of Tang and Xiaobolu attacked Tubo, taking tens of thousands of prisoners. After several years, Tubo did not dare to invade Xiaobolu again, and the west road of Tubo's invasion of Anxi settled down.

Ying Zheng: "Where is Xiao Bolu?"

Yang Guang: "Tang Feng is so strong, he just won't give up an inch of ground!"

In the 13th year of Kaiyuan, the King of Khotan colluded with the Turks and the Hus to rebel.

In the 15th year of Kaiyuan, Zhao Yizhen, the deputy governor of Anxi, defeated Tubo in Anxi City and Quzi City.

Under the joint attack of Datang and Dashi, Tuqishi gradually declined.

In the 22nd year of Kaiyuan, Tubo broke the Da and Xiaobo laws and invaded the southern line of Congling.

In the 27th year of Kaiyuan, Gai Jiayun led the Tang soldiers to sweep away the remnants of Tuqi Shi. The power of the Tang Dynasty returned to Suiye and Bahana, and the soldiers pointed directly at Talas.

In the same year, Gongyue, Chumukun and other original Tuqi Shi Zhenzhu River north affiliated to the Tang Dynasty.

At the end of the Kaiyuan period, the little Boruna's daughter from Tubo became his wife, so she became attached to Tubo, and more than 20 countries in the Western Regions scrambled to be the first to attach themselves to Tubo.

Ying Zheng: "It seems that the big and small Bolu are one of the vital gates of the Anxi theater. With the big and small Bolu in hand, Congling is safe. Unfortunately, without a map in hand, it is impossible to know the specific locations of these countries."

In the sixth year of Tianbao (747 A.D.), Gao Xianzhi, the deputy governor of Anxi, led an army of [-] people to conquer Xiaobolu.

After more than four months of hard marching, Gao Xianzhi crossed the Pamirs and arrived at the dangerous city of Lianyun Castle.

Gao Xianzhi went to two cities in a row, captured King Xiaobolu and Princess Tubo and returned to the court, Xiaobolu and more than 20 countries in the Western Regions reattached to Tang.

In the eighth and ninth years of Tianbao, Gao Xianzhi, the governor of the four towns of Anxi, successively destroyed Sapi, Boxian, and Qie (qie) Shiguo (now northern Pakistan).

Many conquests made Gao Xianzhi famous in the West, known as the "Lord of Chinese Mountains"!
Ying Zheng: "This person has made great contributions to being in Anxi, but how can the name of "Lord and King" be taken over by one side!"

Liu Che: "Gao Xianzhi can indeed fight!"

Li Shimin: "This general has been in Anxi for too long. Although the general cannot be transferred frequently, the general will live in one place for a long time, which is a great hidden danger for the country!"

In the 12th and 13th years of Tianbao, Feng Changqing successively broke the Dabo Law and broadcasted immortals.

So far, the Tang Dynasty has achieved a comprehensive victory over Tubo, and the Tang Dynasty's power in the Western Regions has also reached its peak!

It is said in history that "it was a time when China was prosperous and powerful. From Anyuan Gate (Chang'an City Gate) to the west, the Tang Dynasty was [-] miles away. Luyan faced each other, and there were mulberry trees and wilderness."]

Liu Da: "The national power of later dynasties is so strong..."

Cao Cao: "Cao Cao is willing to conquer the west for the great Han general, and conquer the west for the great Han!"

Sima Yan: "... I know that Da Jin was destroyed by the barbarians on all sides. Your Tang Kingdom has laid down such a large land, and you will only face more Hu tribes. If you don't handle it properly, the rise and fall will only be in the hands of the barbarians. Overnight!"

Yang Guang: "The Western Regions are really vast. I am guilty of not being able to restore the prosperity of the Han Dynasty!"

Li Shimin: "Li Longji's generation of Tang Dynasty handled the Western affairs well!"
