In the face of the smooth flow of the Silk Road, the first thing that is red is Tuyuhun in the northwest. This Tuyuhun was originally a branch of the Xianbei Murong tribe in eastern Liaodong, a tribe-like country located in the Qilian Mountains and the upper valleys of the Yellow River. During the Five Dynasties and Ten Kingdoms, Tuyuhun took advantage of the endless war in the Central Plains and led his troops to control Qinghai, Gansu and other places.

During the Sui Dynasty, he fought against Tuyuhun twice, recaptured the lost land, and set up four counties: Heyuan, Xihai, Shanshan, and Momo. However, due to the turmoil at the end of the Sui Dynasty, Tuyuhun recaptured Qinghai and always threatened the Central Plains and Gansu. If it weren't for Li Tang's foothold in Guanzhong, he would take control of Gansu first. Gansu is only afraid that it will be like Liaodong in history, and let Tuyuhun take advantage of the chaos to seize it.

Tuyuhun has always coveted a place in Gansu, and because of this, the Tang Dynasty has had deep hostility towards the Tang Dynasty since its founding, and it has become one of the headaches of the Tang Dynasty. It wasn't until Li Jing, Luo Shixin, and Li Shiji broke through the Turks in the north and fought the Tang Dynasty that Tuyuhun reined in and didn't dare to move.

However, the Tang Dynasty befriended the Western Regions and reopened the Silk Road, which stimulated Tuyuhun's sensitive nerves.

The Silk Road is a collective term that began in ancient China and was an ancient commercial trade route connecting Asia, Africa and Europe.

After years of development, the Silk Road is not a fixed road, but several, the Northwest Silk Road and the Southwest Silk Road are included, in different regions, different periods, with different routes. One of the most famous is the trade road opened by Zhang Qian during the reign of Emperor Wu of the Han Dynasty, starting from the two major commercial cities of Chang'an and Luoyang, and passing through the Hexi Corridor to Dunhuang. From Dunhuang, it is divided into two roads: the south road from Dunhuang through Loulan, Khotan, Shache, through the green mountains and now Pamir to Dayueshi and rest. to the west to Tiaozhi and Daqin; The north road runs from Dunhuang to Jiaohe, Qiuci and Shule, and crosses the green ridge to Dawan. Go west to rest and reach Daqin. The second is the Qinghai Road of the Silk Road.

During the period of the Northern and Southern Dynasties, the whole country was in turmoil. The Hexi Corridor has also seen a situation in which the heroes are divided, resulting in frequent wars. Hexi Road is often blocked, and Qinghai Road has ushered in the peak of development. At that time, the north of the Yangtze River, including the Hexi Corridor, was controlled by the Northern Wei Dynasty, the south of the Yangtze River was controlled by the Southern Dynasty, the territory of the Northern Wei Dynasty was controlled by Rouran to the north, and the south of the Hexi Corridor was controlled by Tuguhun, and the Northern Wei Dynasty was the enemy of Rouran and the Southern Dynasties. The economically developed Southern Dynasties could only trade with Europe, the Western Regions, and Rouran from Sichuan to Qinghai, and from Xining to Golmud via Dulan. Then go northwest through Mangya, enter Ruoqiang in Xinjiang, and then go west to Europe from Ruoqiang's South Silk Road; or to the north through Gaochang to the east to Rouran; Or from Xining through Dulan, northwest to Daxiao Chaidan, across the Altun Mountains to Dunhuang.

Qinghai Dao also went to glory during this period, and the one who benefited the most was Tuyuhun of Qinghai Dao.

Tuyuhun also attached great importance to the Qinghai Road, the lifeblood of the country's economy, and took great pains in the management of the Qinghai Road, opening up a number of new channels to reconnect the interior and the Western Regions. In order to maintain Aomi Road. The Tuyuhun people not only took on the important tasks of guiding the direction, providing interpreters, and armed escorts, but also actively engaged in transit trade with Hu merchants from Central and West Asia. They trafficked Qinghai and other specialties to the Southern and Northern Dynasties, and then transported silk, cotton, porcelain, ironware, tea, and paper from southern China to Tuyuhun, where they resold them to countries in the Western Regions. One seeks welfare. Tuyuhun also prospered and became powerful because of Qinghai Road and became a hegemon in the northwest.

However, the rise of the Tang Dynasty changed this qiē.

Although most of the Western Regions are currently under the control of the Western Turks. However, the Western Turks used force to subdue people, and in diplomacy they were far less popular than the Tang Dynasty's combination of rigidity and softness. The kings of all countries in the Western Regions have sent people or personally to the Tang Dynasty to express their attachment. Li Tang's envoy was also very well received in the Western Regions. Restoration of Silk Road traffic. The most convenient Hexi corridor is unimpeded, and the pivotal function of Qinghai Road in the Northern and Southern Dynasties gradually disappeared.

How can there be a fool in this multinational businessman who does trade, compared to the bad Qinghai Road, the Hexi Corridor is obviously convenient, and the Hexi Corridor is naturally chosen......

Tuyuhun's biggest reliance, Qinghai Road, is also declining.

There is no such thing as the best of both worlds. For its own development, Datang inevitably cut off the economic lifeline of Tuyuhun. This snatching people's money is like killing their parents, Tuyuhun was already extremely unfriendly with the Tang Dynasty because of the relationship between Gansu and the Tang Dynasty, and now it has cut off the economic lifeline......

Looking at the prosperity of the Hexi Corridor and thinking about the current situation in Qinghai Road, Fu Yun, the Khan of Tuyuhun Busaba, and King Tianzhu, the minister of Tuyuhun Quanchen, were jealous in their hearts, and attacked Hexi again, intercepting and killing merchants along the way.

Regarding Tuyuhun's abnormal movements, Li Tang had also been prepared for a long time.

In the face of this inevitable situation, Li Shimin had already arranged for Duan Zhixuan, the general of Zuo Xiaowei, to be stationed in the Ganliang generation, to resist the disturbance of Tuyuhun on the one hand, and to protect the merchants traveling between the east and west from Tuyuhun on the other.

The Tang Dynasty, especially in the early Tang Dynasty, produced many famous generals, Duan Zhixuan raised troops with Li Yuan, and was also a brave and warlike cattle man under Li Shimin.

Fu Yun saw that it was ineffective, and he was even more furious, and gathered Tuyuhun's army to directly attack Liangzhou.

Tuyuhun's attack on the silk trade road and the arrival of soldiers under the city of Liangzhou are two concepts, and Li Shimin, as the emperor of the Tang Dynasty, will never allow such a provocation of the dignity of the Tang Dynasty. Immediately issued a battle order, appointed Duan Zhixuan as the head of the Xihaidao march, and led the border army and the soldiers and horses of the tribes such as Qibi and Dangxiang to conquer Tuyuhun.

Duan Zhixuan led the border soldiers of the Tang Dynasty and the two grassland cavalry of Qibi and Dangxiang, who surrendered to the Tang Dynasty, drove straight into the Tang Dynasty and defeated Tuyuhun.

Duan Zhixuan led the army to pursue more than 800 miles, and directly killed Qinghai Lake, fearing that he would be defeated too deeply, so he did not dare to go deep, and led the crowd to return triumphantly.

In this battle, Duan Zhixuan destroyed the army and defeated the enemy, led the Tang army to go deep into the Tuyuhun mansion and beheaded more than 10,000 people.

Duan Zhixuan's name also spread far and wide because of this battle, and it shook the Western Regions.

By the way, Duan Zhixuan's merits were so frightening, but Li Shimin was furious and recalled him to Chang'an to remove him from his official position.

Winning a big victory but being punished is not because Li Shimin does not reward and punish him, but because in Li Shimin's view, this is a "defeat".

The Tang Dynasty sent troops, not to win Tuyuhun, not to win, but to destroy Tuyuhun. Duan Zhixuan failed to destroy Tuyuhun, that is a failure, no matter how beautiful his record is.

This is also the prestige of the early Tang Dynasty, during this period Li Tang had a concept, the foreign battle is not destroyed by the other party is a failure......

In response to Duan Zhixuan's punishment, the DPRK and China also had certain objections.

Pingyang also complained that Li Shimin's punishment was a bit harsh, and Luo Shixin raised Xiaohuzha high with both hands and grimaced at him.

Xiaohuzha is worthy of being a baby conceived in November, growing up very strong, growing up very fast, this is only a year old can already open his mouth to call his father, babbling is particularly interesting.

Hearing Pingyang say this, Luo Shixin said: "It's no wonder that His Majesty has the ambition of Emperor Qin and Han Wu, but he does not have the capital of Emperor Qin and Han Wu, so he thinks about things and wants to achieve the greatest results at the lowest cost." It's just that Duan Zhixuan is a general, but he is not a famous general like Pharmacist, and it is not so easy to do that. Rest assured. His Majesty knew very well in his heart that this incident was an accident. He was given a task that was beyond Duan Zhixuan's ability, and it was not surprising that he failed. It's just that the fighter plane is fleeting, and he has to gamble. ”

Li Shimin expected that Tuyuhun would find trouble with the Silk Road, but he did not expect that Tuyuhun would have the courage to fight the Tang Dynasty and make the Tang Dynasty an enemy. After all, there is still a huge gap in the strength of the two sides.

Tuyuhun is a once-in-a-lifetime opportunity.

Defeat the attacking enemy, pursue the defeated army, and directly take advantage of the victory to enter the hinterland of Tuyuhun and destroy Tuyuhun in one fell swoop. The idea strategy has a certain feasibility, but this requires the master to have a certain ability and courage and the ability to control the overall situation.

At that time, Li Shimin had no time to transfer troops from Chang'an, and he didn't have time to make more arrangements. If he spends time arranging for troops, Tuyuhun, as a nation on horseback, will definitely flee.

In that situation, Li Shimin could only choose to make a gamble and use the identity of Tian Khan to transfer the tribes such as Qibi and Dangxiang to let Duan Zhixuan fight...... With Duan Zhixuan's ability, it is not difficult to win Tuyuhun, but it is somewhat beyond his ability to drive straight into extinguishing Tuyuhun, but he has no choice.

The results are not as expected, but they are also within the budget. Duan Zhixuan played beautifully, but after all, it was a little bit worse. This is such a little bit that determines the difference between a general and a famous general.

Li Shimin should just be angry for a while, and he won't really blame Duan Zhixuan.

Just as Luo Shixin thought, not long after Li Shimin removed Duan Zhixuan's position, he reinstated his official position.

This time failed to succeed, Li Shimin gathered his strength and planned a second chance.

However, just when Datang focused on the Western Regions, a secret meeting against Datang was held in Liaodong.

The envoys of Goguryeo, Baekje, and Yamato gathered in one place.

The relationship between Yamato and Baekje was that of Lao Tzu and his son, and there was no superfluous interaction with Goguryeo, but Baekje secretly conspired with Goguryeo to deal with Silla and signed an offensive and defensive alliance.

Baekje Wuwang Fuyu Zhang's own ability is not outstanding, very average, but he has a strength, a cheeky mouth, and a superb diplomatic ability.

Because of the relationship between the Yamato Kingdom, Yamato and Baekje were severely sanctioned by the Tang Dynasty, and they were extremely severe in their development.

In the face of this terrible situation, Yamato and Baekje hugged each other with tears in their eyes to keep warm, and with deep hatred for the lackeys of the Silla people who were completely dependent on the Tang Dynasty, they unanimously decided to beat the dogs of the Tang Dynasty first, and then deal with the master.

When they made a covenant with each other, they unanimously looked at Goguryeo with the intention of pulling him into the water. (To be continued......)
