Tubo suddenly raised an army to invade the world. As soon as the news came out, it immediately shocked the government and the people. Especially for Li Shimin, who was about to go to Mount Tai for the Fengshan period, he was even more shocked. After reacting, he almost smashed Liangyi Palace.

Li Xiu had previously reminded Li Shimin to be careful of the frontier and not to take the opportunity to invade the Tang Dynasty. At that time, Li Shimin also listened to it. In his opinion, the most likely incident was the Western Turks in the Western Regions or Xueyantuo in the northwest. Therefore, he also secretly ordered people to strengthen their defense in these two directions. As long as the other party dared to send troops, he would be hit by the Tang Dynasty.

But what Li Shimin never expected was that the accident happened this time was the southwest. It was not the first time that Tubo had a conflict with the Tang Dynasty. In the past, Tubo had launched a large-scale attack on the Tang Dynasty, but was severely scolded by Li Shimin. Since then, Tubo has taken the initiative to submit tribute.

However, although Tubo surrendered to the Tang Dynasty, the actual relationship between the two countries was still not very good, and there were some small conflicts on the border from time to time, but the scale was not large, and there were no essential conflicts between the two countries. In addition, Tubo was located on the plateau and the Tang Dynasty could not go up, so on the surface, the two countries maintained a peaceful relationship.

It is probably because of the above reasons that Li Shimin was not guarding against Tubo, but he did not expect that it was Tubo, which had never had any major conflicts, but suddenly launched an army to invade the Tang Dynasty. However, the reason why Tubo invaded the Tang Dynasty was very interesting, not to cause trouble for Li Shimin's Fengshan, but because of other reasons.

According to the war reports sent by local officials in Songzhou, since Tubo surrendered to the Tang Dynasty, the two countries have also set up border cities on the border, which facilitates trade between the two countries. There are even some bold merchants entering each other's territory to do business. For example, there are some Tubo merchants in Chang'an. Although Tubo is located on the plateau, some Tang Dynasty merchants who are worth money and live to venture into Tubo, because the profits of a trip are too generous. A small piece of tea brick can sell hundreds of times the profits in Tubo, which is easier than robbing money.

However, as the exchanges between the two countries became more and more frequent, a situation occurred, that is, after some Tubo people saw the prosperity of the Tang Dynasty, they also yearned for it. In addition, Tubo was not a central group like the Tang Dynasty, but a national structure similar to a tribal alliance. There were countless tribes of all sizes within Tubo. These tribes were mainly Songzan Gampo, but their internal management was under their own control, and Songzan Gampo did not want to interfere.

Some Tubo tribes saw the prosperity of the Tang Dynasty, and the Tang Dynasty also controlled some plateau areas. Especially after annexing Tuyuhun, the Tang Dynasty bordered Tubo, and the exchange between the two sides became more convenient. So under this situation, many tribes moved to areas controlled by the Tang Dynasty to live, which was convenient for trade with the Tang Dynasty. Moreover, under the rule of the Tang Dynasty, they could also get various preferential conditions, and even receive relief from the Tang Dynasty when encountering snow disasters.

At the beginning, the only small tribes that moved to the Tang Dynasty were on the edge of Tubo. They were not valued at all, and even a snow disaster could destroy more than a dozen small tribes. In order to protect themselves, these small tribes moved to the Tang Dynasty one after another, and then settled under the guidance of Tang officials, forming some very primitive towns, and their lives were getting better and better.

However, as time went by, more and more Tubo people knew the advantages of living in the Tang Dynasty, so more people were moved, and even some larger tribes collectively entered the Tang Dynasty's territory.

As more and more Tubo people entered the Tang Dynasty to live, Tubo couldn't stand it anymore. After all, they lived on the plateau and had a small population. If they continued to lose like this, it would not take long before the Tubo side near the Tang Dynasty would be gone.

Under such circumstances, Tubo naturally demanded people from the local officials of the Tang Dynasty, and also asked the Tang Dynasty to prohibit the Tubo people from entering the country again. However, this request was rejected by the Tang Dynasty officials because population was also a very important political achievement for these local officials. Moreover, the Tang Dynasty is now strong. In the past, Tubo was a defeated general under the Tang Dynasty, so naturally he did not take Tubo's request to heart.

As a result, Tubo was naturally extremely annoyed. In addition, some time ago, Songtsen Gampo, who was unwilling to give up, once again asked Li Shimin for marriage, but was rejected. So Songtsen Gampo, who was so angry, raised tens of thousands of troops to invade the border of the Tang Dynasty again, but was blocked by the defenders in Songzhou. Now the two sides are also in a tug-of-war.

"Child Songzan, do you really think I dare not kill you?" In Liangyi Hall, Li Shimin angrily overturned the desk, pulled out the sword beside him and roared at the sky. He was not so angry. After all, he was about to go to Fengshan Mountain, which was his biggest wish now. But now such a big thing happened on the border. If it was not handled properly, I am afraid that Fengshan would be ruined this time.

"Your Majesty calms down. The most important thing now is to mobilize a large army to rescue. Although Tubo has not yet attacked our Tang Dynasty, Tubo is not a small country after all. If there is a further increase in troops, Songzhou may not be able to defend it." Faced with Li Shimin's anger, Changsun Wuji stepped forward without fear and suggested that Songzhou is the main transportation route between Tubo and the Tang Dynasty, so every time Tubo sends troops, he will almost attack Songzhou.

Fang Xuanling and others agreed to Changsun Wuji's suggestion, and even Li Xiu expressed support. Speaking of which, Li Xiu should not have been here, but today Li Shimin summoned all the ministers to discuss the Fengshan period of Mount Tai and was about to leave in two days, but unexpectedly, he suddenly received an urgent report from Songzhou, and then he learned about the Tubo's troops.

Although Li Shimin was furious, he did not lose his mind after all. After losing his temper, he immediately began to discuss the matter of sending troops with his ministers. Soldiers, major national affairs, and military expeditions have always been a very systematic matter. It is not just as simple as mobilizing the army. In addition, logistics, routes, combat plans, etc. must be prepared in advance.

In the afternoon of the same day, the plan for sending troops was decided. During the morning court the next day, the appointment of sending troops was issued. The entire Tang Dynasty also rotated like a strict machine. It was estimated that tens of thousands of troops would arrive at the Songzhou front line in no time.

However, what no one expected was that on the afternoon of the third day, when the army's mobilization had just begun, Songzhou sent a war report at a rapid pace. This time it was a good news. However, when Li Shimin and the civil and military officials in the court doubted the authenticity of the good news, because the content on the good news was too unbelievable.

The date of signing the Songzhou news was only five days apart from the last battle report, but it was only three days apart from the delivery to Chang'an. It was probably because the news was urgent, so the soldiers who reported the news tried their best to go on their way and only delivered it two days in advance. According to this news report, the tens of thousands of troops of Songtsen Gampo had been defeated and were defeated in disgrace. This was originally a happy thing, but the content on the news was too amazing.

It turned out that Songtsen Gampo led his troops to attack the Tang Dynasty, and the Tang army also sent troops to meet the enemy. As a result, the two sides launched a decisive battle in the southwest of Songzhou City. Although the Tang army did not have an advantage in numbers, because they had sufficient troops and had enough food, and had defeated Tubo before, they had no psychological advantage, so they did not lose at all. Songtsen Gampo was probably also worried, so they were very cautious in using their troops, which led to a stalemate between the two sides.

After the Tang Dynasty annexed Tuyuhun, it also stationed many troops there. Now Tubo is attacking Songzhou, so the surrounding garrisons also go to rescue them. As a result, on the third day after Songzhou sent off the war report to the court for help, a mansion soldier who was originally stationed in Tuyuhun also arrived at the battlefield. The mansion soldier was not large, only one team, that is, one hundred and fifty, and the commander was a Guoyi Duwei.

The Tang Dynasty was a system of government troops. Each government troops had one Zhechong school lieutenant and two Guoyi lieutenant. However, the government troops were divided into three levels according to the number of troops, with a number of people ranging from 1,000 to 4,000. There were few people in Tuyuhun, and the government troops often did not recruit enough people. The Guoyi lieutenant who came this time was a low government commander, and the troops of each government were only about a thousand people. Now, it was already considered to be a 150-strong lieutenant.

However, what no one expected was that it was this small team of only 150 people who broke the balance on the battlefield during the battle the next day. In particular, the commander Guoyi, who led more than 100 cavalry under his command, actually broke through the defense line of the Tubo people, penetrated the Tubo army in one fell swoop, and almost rushed to Songtsen Gampo.

Faced with this powerful Tang cavalry, Songtsen Gampo was also very scared and hurriedly retreated. As a result, when he retreated, the Tubo army was completely dissatisfied. The chief general of the Tang army also took the opportunity to suppress the entire army and finally defeated the Tubo people in one fell swoop. Then there was a cruel pursuit. According to the good news, the Tang army beheaded more than 3,000 enemy troops in this battle and seized countless materials.

And this was just the beginning. The Tang army did not allow Songtsen Gampo to escape, but sent several elite cavalry to pursue him. You should know that the Tang army is no longer the past. In the past, the Tang army mainly lived on the plains, and its combat effectiveness would be greatly reduced when it went to the plateau. Now many Tang army is stationed on the plateau, and some are even recruited directly from the local ethnic groups, so there is no need to worry about the plateau reaction at all. As a result, this pursuit also penetrated into the territory of Tubo.

The result has not yet come out, but when the Zhanjie report was delivered, the Tang army in front had already bit the tail of the defeated Tubo Ganbu army. If they were lucky, they might be able to capture Songtsen Ganbu alive.

No one expected that the crisis in Tubo would be solved so easily, and he won such a big victory. The most important thing was naturally the invincible Guoyi Commander. At first, Li Xiu suspected that Xue Rengui had gone to Tubo, but now Xue Rengui was clearly guarding the city gate at Xuanwu Gate, so it was impossible for him to leave without leaving. It was not until later when he saw the name on the victory report that he remembered a powerful general who was almost forgotten by him.
