Yuan Gai Suwen was born in the Goguryeo clan, and his father is Yuan Taizuo, a former Goguryeo Eastern Lord, and a great pair of Lu.

When the Sui Dynasty attacked Goguryeo for the second time, Yang Xuangan rebelled in the rear, and the north and south had different attitudes towards Yang Xuangan's rebellion and had great differences.

The north is represented by a military group, they support the rebellion against the Sui Dynasty army while Yang Xuangan rebelled, and the leader was Yuan Taizuo, while the south supported the rebellion of Yang Xuangan, the internal instability of the Sui Dynasty, and the Sui Dynasty negotiated a truce, and the representative figure was King Rongliu, who had not yet succeeded to the throne.

Yuan Taizuo, this is a powerful minister of Goguryeo who can compete with King Yeero, and also represents the power of the military.

So since then, King Rongliu has been quite at odds with Yuan Taizuo's family. After that, Yuan Taizuo wanted his eldest son Yuan Gai Suwen to inherit his position as the Eastern Lord and the Great Pair of Lu, but he was also strongly opposed by the Rongliu Wang family and failed to achieve it, and he did not see the eldest son inherit his position until he died.

But it's normal, at that time, Yuan Gai Suwen was only thirteen years old, a little kid, how could he inherit the position of the prime minister like the eastern lord and the big pair of Lu.

But Yuangai Suwen didn't think so, he only knew that his family and King Rongliu were not dealing with each other, and it was King Rongliu who prevented him from inheriting his father's position, so in fact, after Yuan Taizuo's death, he still inherited the Eastern Lord and the Great Pair of Lu, but he has always been angry with King Rongliu, who has inherited the throne of Goguryeo.

King Rongliu naturally dislikes Yuangai Suwen very much, but Yuangai Suwen has been very capable since he was a child, and he has the support of the military, so he is already a powerful minister at the age of sixteen or seventeen, so that he, the king, does not dare to target too much.

No king wants to see a minister under his command who can't control him, or a minister with military power.

Therefore, after a rift with the Tang Dynasty, King Rongliu later found an opportunity to send Yuangai Suwen to repair the Great Wall.

The northeast from Fuyu City, southwest to the seaside more than 1,000 miles of the Great Wall Yuan Gai Suwen this repair on the ten years.

Even if Goguryeo and Baekje jointly used troops against Silla, King Yeongliu did not think of letting Yuangae Suwen, the de facto military leader, lead even one soldier to the front.

It seems that he wants to build the Great Wall to death.

Yuangai Suwen was very dissatisfied, so he spoke badly, saying that the Tang Dynasty would definitely send troops to intervene in the war, and when the time came, Goguryeo Baekje would definitely not be able to resist, and then he would be the one who turned the tide, no matter how many people the Tang Dynasty sent, he would let the Tang Dynasty soldiers and horses come and go, and bury all the bones of Goguryeo.

Yuan Gai Suwen viciously cursed Goguryeo, and it would be just that the Baekje coalition army would be stopped by the Tang Dynasty, and he even said that if the Tang Dynasty sent troops, the Tang Dynasty would have no return, which was very, extremely inappropriate when the Tang Dynasty had not shown malice to Goguryeo, and would be regarded as a provocation by the Tang Dynasty.

Goguryeo Baekje has always been very worried that the Tang Dynasty will be blocked by the Tang Dynasty, especially since the Tang Dynasty just wiped out the Western Regions last year, which aggravated their worries.

The king of Goguryeo almost died of anger, and he was already very dissatisfied with Yuangai Suwen, and this time he was directly preparing to kill Yuangai Suwen.

King Yeongliu and his confidants planned to get rid of some of the most powerful generals in Goguryeo, and the first one was to take out the most threatening threat to his throne, Yuangae Suwen.

As a result, the plan was leaked, and Yuangai Suwen found an excuse to return to the national capital, first set up a banquet to invite the officials of the court and China, and killed the henchmen of King Rongliu at the banquet in one fell swoop, and then led troops into the palace to divide the body of King Rongliu.

"The rebellious ministers and thieves are all punished for it, and such a rebellious thing happened in Goguryeo, a subject country of the Tang Dynasty, I deeply regret it, as the suzerain, how can such a traitor control the political and military power of the court, I will never allow it. Someone is coming, and he will quickly summon him and order Chu Suiliang and others to draft a document to solicit and announce it to the world."

Yes, just now a group of ministers opposed it justifiably, and now Goguryeo directly sent the emperor a justifiable reason to send troops, and the civil officials couldn't oppose it if they wanted to.

Soon, the conquest was announced to the world, and the Tang Dynasty's mobilization of troops against Goguryeo was a foregone conclusion.

As a result, things were so unsmooth, just when Li Shimin issued a holy decree to dispatch troops, a few days later, an urgent report came from Bingzhou.

Xue Yantuo sent troops to the Tang Dynasty.

However, Xue Yantuo himself did not admit to sending troops to the Tang Dynasty, because they attacked the Turkic people in the steppe, as well as nomadic tribes such as the Uighurs.

Even if these tribes have long become the people of the Tang Dynasty, and the grasslands where they are located are governed by officials sent by the Tang Dynasty, Xue Yantuo bit to death that he was not attacking the Tang Dynasty, but the Turkic people who attacked and the Hui people who attacked.

But, cover your ears and steal the bell to top a fart.

The grassland is no longer the grassland of the past, and the grassland is not even the land of the nature of the feudal state that was established by the Tang Dynasty before, but the actual sovereignty and governance are firmly in the hands of the Tang Dynasty.

That is the name of the Tang Dynasty, as well as the de facto territory of the Tang Dynasty.

Xue Yantuo attacked the Turks in the land of the Tang Dynasty, and attacked the Hui people, that is, the people of the Tang Dynasty who attacked and set foot on the land of the Tang Dynasty.

This kind of thing, Datang has already taught Xue Yantuo a profound lesson two years ago.

But the dog can't change to eat, Xue Yantuo's move is just that he thinks that the Tang Emperor patrolled Luoyang, sealed Mount Tai, and took away a large number of elite troops, so he was ready to take advantage of the situation and invade the territory of the Tang Dynasty.

Xue Yantuo people know this very well, and the Tang people are not stupid, and they know even more what their idea is.

Therefore, when Xue Yantuo Khan Yinan sent his eldest son Dadu to lead troops to attack the pastures of the Turkic tribes, trying to exterminate the Turks and Hui people before the Tang Dynasty provided assistance, or drive them out of the grassland, reach the fact of occupying the grassland and then negotiate with the Tang Dynasty to seek permanent occupation, Shi Li Ji, the governor of the capital of the state who got the news, directly led the army of the state to kill the grassland without the emperor's order.

Not having an imperial order is not a problem for Li Ji at all, because now it is not as good as before, no matter which subject country was invaded and occupied, the generals on the Tang side had to get the imperial order if they wanted to send troops.

But now the grassland is the territory of the Tang Dynasty, Li Ji is the governor appointed by the emperor to guard the border, and nearly 100,000 soldiers in the state are used to guard the Shuozhou eyeline, and also to protect the life and property of the Turks on the grassland and the people of the Tang Dynasty.

It is the responsibility to defend the land, and at this time, it is Li Ji's responsibility to directly send troops to the grassland, and the emperor will not blame Li Ji for being angry at all because he did not give an order.

Xue Yantuo didn't understand the situation at all, and thought that Datang would pass the message back and forth to order how much time would be delayed.

Then Li Shimin, who got the news, was directly furious, he didn't even find Xue Yantuo, but Xue Yantuo called the door first, which was worth it.

Urgently change the order, Li Ji, Li Daozong and others don't have to come, Li Shixian, Li Daozong, Zhi lost Sili, Qi Bi He Li and others commanded Shuo, And, Fen, Ji, Lan, Dai, Xin, Wei, Yun Jiuzhou Bingzhen Shuozhou, Wei Chigong, Xue Wanche, Ashina Sheer, Zhang Jian, Li Daliang, Xue Guwu and other Fasheng, Xia, Yin, Sui, Dan, Yan, Dun, Fang, Shi, Xi Shizhou Bingzhen Shengzhou, Cheng Yanjin, Zhang Liang, Zhang Shigui and Li Xianyu and other Ling, Yuan, Ning, Yan, Qing five prefectures Bingzhen Lingzhou.

Li Jing, Hou Junji and others sat in Chang'an, Beijing.

The general mobilization of the whole army was directly aimed at destroying Xue Yantuo, and then the civilian officials found that the special generals were about to be transferred, didn't they say that they were going to conquer Goguryeo, this document has been issued, Your Majesty, you are going to break your word.
