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

During the Sui Dynasty, Tuyuhun fought twice, and took back the lost land, setting up Heyuan, Xihai, Shanshan and the four counties. However, due to the turmoil at the end of the Sui Dynasty, Tuyuhun seized a place in Qinghai again and threatened the Central Plains and Gansu. If Li Tang had not established himself in Guanzhong, he would have taken control of Gansu first. Gansu would have been like Liaodong in history, allowing Tuyuhun to seize it in the chaos.

Tuyuhun has always coveted a place in Gansu. Because of this, the Tang Dynasty had deep hostility towards the Tang Dynasty since its founding, and became one of the headaches of the Tang Dynasty. It was not until Li Jing, Luo Shixin and Li Shiji defeated the Turkic people in the north and fought the magnificent style of the Tang Dynasty that Tuyuhun had just restrained himself and dared not act rashly.

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

The Silk Road is a general term, which started in ancient China and connected Asia, Africa and Europe with commercial and trade routes.

After years of development, the Silk Road is not a fixed road, but several, including the Northwest Silk Road and the Southwest Silk Road, and has different routes in different regions and periods. The most famous of these is the business road opened by Zhang Qian during the reign of Emperor Wu of Han. It starts from Chang'an and Luoyang and goes through the Hexi Corridor to Dunhuang. It starts from Dunhuang and is divided into two north and south roads: the south road from Dunhuang through Loulan, Khotan, Shache, crosses the Pamir to the Dayuezhi, and goes west to the Zhizhi and Daqin; the north road from Dunhuang to Jiaohe, Kucha, Shule, crosses the Pamir to Dayuan. Go west to the Qinghai Road.

During the Southern and Northern Dynasties, the country was in turmoil. There was also a situation of heroic separatism in the Hexi Corridor area, resulting in frequent wars. Hexi Road was often blocked and blocked, and Qinghai Road also ushered in the peak of development. At that time, north of the Yangtze River, including the Hexi Corridor, south of the Yangtze River, controlled by the Southern Dynasties, north of the Yangtze River, controlled by the Southern Dynasties, south of the Northern Wei Dynasty, controlled by the Tuyuhun, south of the Hexi Corridor, and the Northern Wei and Rouran were enemies. The economically developed Southern Dynasties and Europe, the Western Regions, Rouran could only enter Qinghai from Sichuan, from Xining through Dulan, to Golmud. Then northwest passed Mangya, enter Ruoqiang in Xinjiang, and then west from Ruoqiang's Silk Road to Europe; or northwest through Gaochang to east to Rouran; or from Xining through Dulan, northwest to Dachaidan, and northwest to Dunhuang, cross Aljin Mountain to reach Dunhuang.

Qinghai Road also went to glory during this period, and the biggest benefit was Tuyuhun, which controlled Qinghai Road.

Tuyuhun also attached great importance to the country's economic lifeline. He worked hard to manage Qinghai Road and opened up many new channels to reconnect the mainland and the Western Regions. In order to maintain Qinghai Road, the Tuyuhun people not only took on the important tasks of guiding the direction, providing translation, armed escort, etc., but also actively engaged in transit trade with Hu merchants from Central Asia and West Asia. They trafficked specialties such as Qinghai Prefecture to the Southern and Northern Dynasties, and then transported silk, cotton cloth, porcelain, ironware, tea and paper from southern China to Tuyuhun, and then transferred it to the Western Regions countries. In order to seek benefits, Tuyuhun also flourished and became a domineering person in the northwest because of Qinghai Road.

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

Although most of the Western Regions are under the control of the Western Turks, the Western Turks have conquered people with force, which is far less than that of the Tang Dynasty in diplomacy than the Tang Dynasty. Kings of various countries in the Western Regions have sent people or personally to the Tang Dynasty to express their support. The envoys of the Li Tang Dynasty were also very popular in the Western Regions. The Silk Road transportation was restored. The most convenient Hexi Corridor was unobstructed, and the hub function of Qinghai Road during the Southern and Northern Dynasties gradually disappeared.

This multinational businessman who trades is not foolish. Compared with the harshness of Qinghai Road, the Hexi Corridor is obviously convenient and naturally chooses the Hexi Corridor...

The Qinghai Road, the biggest reliance of Tuyuhun, has gradually declined.

There is no such thing as the best of both worlds in the world. For its own development, the Tang Dynasty inevitably cut off the economic lifeline of Tuyuhun. This is like killing parents. Tuyuhun was originally extremely unfriendly with the Tang Dynasty because of the extremely unfriendly 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 of Qinghai Road, Tuyuhun Busabor Khan Fuyun and Tuyuhun's powerful minister King Tianzhu were jealous of him, and they attacked Hexi again and intercepted the merchants and travelers along the way.

Li Tang was also prepared for Tuyuhun's abnormal movements.

Faced with this inevitable situation, Li Shimin had already arranged for the Zuo Xiaowei General Duan Zhixuan to station in Ganliang generation, resisting Tuyuhun's disturbances while protecting the merchants and traveling around the world and protecting the east and west from the attacks of Tuyuhun.

The Tang Dynasty, especially during the early Tang Dynasty, emerged in many famous generals. Duan Zhixuan raised an army with Li Yuan and was under Li Shimin's command. After being given the order, he joined forces with the surrounding tribes such as Qie, Dangxiang, and conscientiously guarded the Hexi Corridor and temporarily safeguarded the safety of the Silk Road.

Seeing that it was impossible to achieve results, Fu Yun was even more furious and gathered the army of Tuyuhun to directly come to Liangzhou.

Tuyuhun's attack on the silk trade road and the arrival of the Liangzhou city are two concepts. Li Shimin, as the Emperor of the Tang Dynasty, would never allow such a provocation of the existence of the Dignity of the Tang Dynasty. He immediately issued a combat order, appointing Duan Zhixuan as the general manager of the Xihai Road marching, leading the border troops and tribes such as Qiebi, Dangxiang to fight against Tuyuhun.

Duan Zhixuan led the border soldiers of the Tang Dynasty and Qiezi who surrendered to the Tang Dynasty, and the two grassland cavalrymen of Dangxiang, and drove straight in and defeated Tuyuhun.

Duan Zhixuan led his army to pursue more than 800 miles and directly killed Qinghai Lake. He was worried about being defeated too deeply, so he did not dare to go deeper, so he led his people back triumphantly.

In this battle, Duan Zhixuan defeated the army and defeated the enemy. He led the Tang army deep into Tuyuhun's mansion and beheaded more than 10,000 people. Tuyuhun was frightened and was about to collapse.

Duan Zhixuan's name was also famous for his martial arts because of this battle, which shocked the Western Regions.

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

The victory was won but was punished. It was not that Li Shimin did not distinguish between rewards and punishments, but that in Li Shimin's view, this was a "lose".

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

This is also the majesty of the early Tang Dynasty. During this period, Li Tang had an idea that if the foreign battles were not destroyed, it would be a failure...

The court also had certain objections to Duan Zhixuan's punishment.

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

Xiaohuzha is worthy of being pregnant for eleven months. She grows very strong and grows very fast. She can call her parents only at one year old, and it is very interesting to be a little bitchy.

Hearing Pingyang say this, Luo Shixin said: "It's no wonder Your Majesty. Your Majesty has the ambition of Qin Emperor and Han Wu, but he doesn't have the capital of Qin Emperor and Han Wu, so he always thinks about things to achieve the greatest results at the lowest cost. It's just that Duan Zhixuan is a general, but not a famous general like Medicine Master. It's not that easy to do that. Don't worry. Your Majesty knows very well that this matter is an accident. He gave a task that exceeds Duan Zhixuan's ability, and it's not surprising that failure is just a fleeting opportunity, and he has to bet."

Li Shimin expected Tuyuhun to find trouble on the Silk Road, but he did not expect Tuyuhun had the courage to fight against the Tang Dynasty and the Tang Dynasty. After all, there was still a huge gap in strength between the two sides.

The arrival of Tuyuhun is a once-in-a-lifetime opportunity.

Defeat the incoming enemy, pursue the defeated army, and take advantage of the victory to enter the hinterland of Tuyuhun, and destroy Tuyuhun in one fell swoop. The idea and strategy are feasible, but this requires the main general to have a certain ability and courage and control the overall situation.

At that time, Li Shimin had no time to dispatch troops from Chang'an and did not have time to make more arrangements. If he took the time to transfer troops to arrange the troops, Tuyuhun, as a nation on the back of a horse, would definitely escape.

In that situation, Li Shimin had to choose one bet, as he as Tian Khan, to transfer tribes such as Qiezi, Dangxiang, and let Duan Zhixuan fight... With Duan Zhixuan's ability, it was not difficult to win Tuyuhun, but he drove straight into and wiped out Tuyuhun, but he was a little beyond his ability, but he had no choice.

The result cannot be said to be as expected, but it is also in the budget. Duan Zhixuan played beautifully, but it was a little worse after all. This is a little bit, which determines the difference between a general and a famous general.

Li Shimin should have been angry for a moment and would not really blame Duan Zhixuan.

Just as Luo Shixin thought, Li Shimin removed Duan Zhixuan's position and then regained his position.

This time, Li Shimin also gathered strength and planned a second chance.

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

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

Yamato and Baekje are the relationship between Lao Tzu and his son, and they have no extra relationship with Goguryeo. However, in order to deal with Silla, Baekje secretly conspired with Goguryeo and signed an offensive and defensive alliance.

According to Baekje King Fu Yuzhang, his ability is not outstanding and very ordinary, but he has a strong and thick-skinned and can speak, and his diplomatic ability is first-class.

Because of Yamato's relationship, Yamato and Baekje were severely sanctioned by the Tang Dynasty, and the situation for them that was developing was extremely severe.

Faced with this bad situation, Yamato Kingdom, Baekje hugged each other with tears in his arms to keep warm. With deep hatred for the lackeys of Silla, he unanimously decided to beat the dogs of the Tang Dynasty first and then deal with the owner.

When they were covenant with each other, they unanimously looked at Goguryeo, intending to pull him into the water. (To be continued, please search for Astronomy, novels are better, updated and faster!
