The Xuanwumen Change, although Li Shimin was forced to launch a counterattack against his father and brothers in order to protect himself, it is undeniable that it is precisely because of this coup d'état that Li Shimin gained friendship with Song Que and Kou Zhong, the leaders of the Jiangnan Coalition Group, and the support they provided, thus obtaining a huge guarantee for his victory, and the Jiangnan Coalition Group also helped Li Shimin in this coup d'état. The best conditions for reconciliation with Li Shimin were obtained: they had a part of the autonomy over the Jiangnan area, and the corresponding alliance was the dissolution of the coalition forces that seized Jiangnan and declared their submission to the rule of the Tang Dynasty.

There is no doubt that the Xuanwumen Revolution and the subsequent news of the dissolution of the Jiangnan Coalition Army are extremely bad news for the Turks who have been waiting for the invasion opportunity in the north. In the face of the Chinese civilization that has completely completed the great cause of unification, the nomads on the steppe do not say that they will be able to benefit from the Central Plains again through coercion and inducement as before, but they may not be able to repeat the story played in the late reign of Emperor Wen of the Sui Dynasty Yang Jian: not only was the powerful Turkic Empire divided into two, but they also had to pay tribute to the Sui Dynasty. Endure all kinds of humiliation.

Because Jieli Khan, who took advantage of the chaos at the end of the Sui Dynasty and enjoyed all kinds of luxuries in the Central Plains, of course, could not accept the coming qiē, so he discussed with Tuli and the leaders of various steppe tribes to attack the Tang Dynasty together.

Originally. In the Turkic Empire, due to Jieli's conquest, a considerable number of tribal leaders united under the command of the little Khan Tuli and fought against Jieli, thus making it impossible for the Great Khan Jieli to concentrate his forces and go south to plunder. However, this time, Jieli's mention was recognized by all the tribal leaders, including the little Khan Tuli, and in the final analysis, although the contradictions between Jieli and the various tribes have almost reached the point of irreconcilability, but even so, they are still all peoples on the grassland, and compared with the Han Empire in the south, they are a family after all. And when the Han civilization in the south completes the unification again, the good days of the peoples on the grassland will come to an end. This result was unacceptable to all the tribes of the steppe, and therefore, this time, they united unprecedentedly and jointly sent troops to attack the Central Plains.

However, it was precisely because of this attack that all the tribes of the entire steppe were united. Therefore, wait for the time for the forces of all the tribes to converge. It was a little longer, and they had to wait for a while until August, when the grass was lush and the horses were fat, and they made a big move south. At this time, a period of time had passed since the Xuanwumen Change, and the Tang Emperor Li Yuan and his retreat to Li Shimin made Li Shimin completely control the shape of the country.

The Turkic cavalry was nearly 200,000 people, and they approached Chang'an with great momentum along the way. The northern border of the Tang Dynasty was in an emergency, and Li Shimin dispatched troops to block all the way, but the disparity in strength made his actions only slow down the offensive pace of the Turks, and could not make the other party stop the pace of advance, so that soon after, the extremely fast Turkic cavalry had already attacked the core Guanzhong area of the Tang Dynasty, and the Turkic forward, even only more than 40 miles away from Chang'an, shocked the capital Chang'an.

Guanzhong was shaken, at this time the entire Guanzhong territory was only tens of thousands, in the face of the overwhelming strength of the Turkic army of 200,000, Li Shimin knew that if he wanted to take the initiative to attack, it would not hesitate to hit the stone with an egg, and Li Shimin himself, because of the attack of the Turks, even thought of the scene when he led his troops to attack Chang'an just ten years ago.

But fortunately, unlike themselves, the Turks have always been not good at attacking cities, so if the whole army retreats, and with the terrain of Guanzhong and the strong walls of Chang'an City, even if the Turkic forces are extremely strong, if they want to conquer Chang'an, it will take a long time, especially during this period of time, Li Shimin can be escorted by the troops from all over the world. The Turks would have to retreat back to the steppe, otherwise they would have been defended by the Tang army.

This is indeed a feasible strategy, and Li Shimin believes that with his own ability, he has commanded the lives of the soldiers, Chang'an City will be impregnable and will not be conquered by the Turkic cavalry, however, in the end, Li Shimin decided to save this plan for the last use, after all, only a thousand days to be a thief, and there is no reason to prevent thieves for a thousand days, once the Turks are unfavorable in the war, they can quickly retreat to the grassland, but the army of the Tang Dynasty can not always gather in the pass to wait for the Turkic attack, especially the Turkic cavalry moves quickly, It can choose a place to break through the Tang Dynasty's border at any time and any place, so if this attack cannot satisfy the Turks, then in the future, the northern border of the Tang Dynasty will inevitably be full of smoke, and the danger to the country and the people will be great.

For Li Shimin, this invasion of the Turks is admittedly a great threat, however, it is not an opportunity, an opportunity to re-sign the alliance with the two Turkic khans, and if Li Shimin can really seize this opportunity and turn it into reality, then there is no doubt that in the next few years, the northern members of the Tang Dynasty, who have just completed the unification of the country, will get a period of time to recuperate and recuperate, so as to gradually restore the vitality of the country.

On the one hand, he ordered all the people near Chang'an City to be under martial law to prevent a sudden attack by the Turks, but on the other hand, he took a group of generals who were absolutely loyal to him, and personally rushed to the front line of the confrontation between the Tang army and the Turks, and then sent envoys to reaffirm and continue the alliance signed between the Tang Emperor Li Yuan and the Turks!

"This time I went to the front line to face the 200,000 Turkic army, and I am not by your side. Be careful! Before leaving, Shi Qingyi said to Li Shimin.

But Li Shimin was so relieved that Shi Qingyi said: "Don't worry, I'll be back soon!" He said: "This time the Turks are menacing, but it is only a sign of their weakness, precisely because the nomadic tribes of the steppe are afraid of the emergence of a unified Chinese empire." That's why they chose to attack the Central Plains in an all-round way at such a season, because this was their last chance!

"And if the Turkic Khan leads the Turkic army to attack this time, then I will be afraid, after all, the Turki are not only brave and resourceful, but also deeply loved by the people of the various tribes in the steppe, so they can get their loyalty, and with the strength of the Turkic cavalry, even if our army can be ten with one. But it is bound to break out in a bloody battle to be able to force its opponents! But fortunately, this time the commander of all the Turks was our old friend, Jieli Khan......"

In his early years, Jieli Khan was a brave general as a Turkic general, but when he inherited the position of Khan of the Turkic Empire, he gradually indulged in pleasures. As a result, both bravery and wisdom have gradually corrupted and disappeared, and now. He became a timid rat who forgot his righteousness, and because of his rampant conquest on the grassland over the years, it aroused the great indignation of various tribes on the grassland, so that at this time, although the Turkic army went south to attack the Tang Dynasty, its internal contradictions were actually extremely strict. Li Shimin believed that under the coercion and use, as well as the operation of related schemes, Jieli Khan, who was always worried about civil strife within his army, would inevitably agree to his conditions and obediently ally with him. Then retreat to the steppe.

In this way, Li Shimin left, and because the Turkic army at this time had advanced to the south bank of the Wei River not far from Chang'an, across the river from the Tang army's defensive forces, so when Li Shimin left Chang'an, he had already arrived in the Tang army's defensive position in just one day.

At this time, the Turkic army was also as Li Shimin thought, the contradiction between the big and small khans was extremely antagonistic, although the Jieli Khan had many troops, but the generals were greedy and the soldiers were tired, so they were not as strong as the Turki Khan's command, and the Turkic generals were also dissatisfied because of the greed of the men and horses under the command of Jieli, occupying most of the looted wealth, but because of the large number of people on the other side and the fact that they went deep into the territory of the Tang Dynasty, they secretly endured it. When Li Shimin arrived at the front, he did not immediately meet with Jieli to discuss the issue of withdrawing from the army, but on the contrary, he first made an appointment to meet with the Turki Khan.

At that time, due to some administrative reasons, the former leader of the Jiangnan coalition Kou Zhong stayed in Chang'an, so when the Turks launched an attack on the Tang Dynasty, Kou Zhong asked to go with Li Shimin and contribute his own strength to resist the Turkic invasion. It can show the Turkic army the support of the separatist forces in the south of the Yangtze River to the Tang Dynasty, thereby weakening the morale of the opposing army.

Therefore, when Li Shimin made an appointment to meet Tuli this time, he took Kou Zhong with him and pressed for himself.

Earlier, Tuli Khan had been brothers with Li Shimin and Kou Zhong, of course, his worship was with a certain utilitarian heart, but it is undeniable that for Li Shimin and Kou Zhong, Tuli has always been full of respect for the two in his heart, thinking that the two are the most outstanding heroes in the Central Plains, and therefore, when he saw Kou Zhong and Li Shimin actually came together, Tuli's heart was surprised, but also vaguely revealed a trace of fear, because from Kou Zhong's attitude, He already knew clearly that this time, the Tang Dynasty was really about to unify the whole world, and this would be the beginning of hell for the nomadic tribes on the grassland.

In Tuli's heart, he thinks that Li Shimin and Kou Zhong are heroes, and in the hearts of Li Shimin and Kou Zhong, Tuli is not a hero, you must know that this Turki Khan is the son of the original Turkic Khan Shibi Khan, when Shibi Khan died, Tuli was only fourteen years old, and at that time, Tuli was regarded as a big trouble by his uncle, Jieli, who had just inherited the Turkic Khan's throne. Determined to get rid of him, fortunately, Shibi Khan left behind a group of subordinates loyal to him during his lifetime, and it was under the protection of these subordinates that the young Turki was able to become a small Turkic khan, and thus escaped the conspiracy of Jieli Khan again and again. to be able to grow up. And it was Tuli who traveled the world after growing up, so he was able to get to know Li Shimin, Kou Zhong and other young heroes of the year.

Since ancient times, heroes cherish heroes, and Kou Zhong, Li Shimin and Tuli are undoubtedly the heroes in the world, so of course the three of them cherish each other, and speaking of which, whether it is Tuli, Li Shimin or Kou Zhong, the characters of the three of them all value righteousness. Keep his promise, and therefore, when Li Shimin reaffirmed the alliance between the Tang Dynasty and the Turks, although he was extremely afraid of the future strong Tang Empire, but for Li Shimin's willingness to keep his promise, Tuli still instinctively chose to believe - in fact, he couldn't help but believe it, because even if the Turks had marched to the vicinity of Chang'an this time, they were facing the Tang army that was waiting for them. The Turkic cavalry, who were not good at attacking the city, might not be able to bargain much for the Tang army, so they made an alliance. Then, after receiving the benefits, retreat immediately, on the contrary, was the most favorable condition for the Turkic army.

However, what will be the future of the Turks when their own side withdraws?

Tuli knew that even if Li Shimin really wanted to make an alliance with his side, he would be greedy for profit. He will inevitably repeatedly reneg on the covenant and plunder south, so that the so-called covenant will naturally become a piece of waste paper. When the Tang Dynasty became strong, it would inevitably use this as a reason to tear up the covenant. Thus launching a major attack on the steppe...... In that case, the Turkic Empire in the steppe will be really dangerous!

But even so, what can he do to stop Jieli from killing himself? The little Khan Tuli knew that with his strength at this time, it would be absolutely difficult for him to do it, and if he started a war with Jieli because of this, and then caused Turkic civil strife, if Li Shimin did not abide by the covenant and took the opportunity to suddenly launch an attack on the steppe, then he Tuli would become a sinner of the Turks through the ages! Turki would never do anything that endangered the Turkic nation, and it was precisely because of this that Turki had no other way out than to choose to believe in Li Shimin's credibility at this time.

However, even if Tuli thought so in his heart, he still did not make any promises with Li Shimin and Kou Zhong in this meeting, after all, although Tuli is a little Turkic khan, but for him, Turkic is a whole, and to let the Turkic army of 200,000 withdraw together, it is necessary to obtain the consent of all the Turkic generals, including Jieli, and Li Shimin is also very appreciative of this, in fact, for Li Shimin, when Tuli appears alone in front of him, His goal has been achieved, and the reason why Tuli was unable to sign any covenant with Li Shimin shows that Tuli has a side that takes the overall situation into account, and is not a selfish villain like Jieli.

So the two sides returned to their respective camps, and in the second day, Li Shimin left the barracks again, this time, he came directly to the front of the military formation of the two armies, stood on the south bank of the Wei River, and invited Jieli to come forward in person, and once again discussed the alliance between the Tang and the Turks. And when Jieli appeared, Li Shimin's duty to speak righteously Jieli was not trustworthy, obviously he had already signed an alliance with Datang, but he repeatedly made treacherous moves to invade the territory of Datang, Li Shimin's voice was extremely confident, which made Jieli, who was already suspicious of Tuli because of the meeting between Tuli and Li Shimin, who was doubtful in his heart, suddenly became more suspicious of Tuli, and Jieli is not Turkic, compared to Turki's loyalty to the Turkic people, selfish Jieli is often considered at the first time, But it is whether his own interests will be lost because of this, and therefore, when he has a deep suspicion of Tuli, naturally, when facing Li Shimin, his heart is empty.

In fact, if Jieli's attitude was tough at this time, or even directly waved the army to launch a fierce attack on the Tang army, Tuli and others might not be willing, but since Jieli was the Turkic Great Khan, his orders, Tuli and others would naturally try their best to obey them, at that time, although the Tang army was in full swing, but with the numerical advantage of the Turkic cavalry army, as well as the courage of the Turks, the number of victories and defeats on both sides was still five or five, but because of Jieli's weak heart, he naturally would not have the intention of fighting with the Tang armyTherefore, in the face of Li Shimin's accusations, and the subsequent intention to re-sign the covenant with Jieli, Jieli was busy borrowing the slope to get off the donkey, under the pretext that because of the abdication of Tang Emperor Li Yuan, so this time they came to re-establish the previous covenant with Li Shimin!

Jieli's words are of course all, but at this time, what Li Shimin needs is actually these words, which can show that Jieli is soft, and therefore, in the subsequent, Li Shimin also generously said that he was not to blame for the past, so the two sides made a covenant on the bridge of the Wei River, and re-signed a non-aggression pact, and as part of the covenant, Li Shimin took out all the wealth stored in the treasury of Zài in the Chang'an area as a condition for the withdrawal of the Turkic army.

As a result, a disaster that was originally enough to cause a huge war in the entire Guanzhong and even in the north was eliminated invisibly within a few days under the effect of Li Shimin's careful use of the heart-attacking technique, and in this covenant, Li Shimin took out a large amount of wealth as an exchange condition for the Turkic retreat, on the surface, Li Shimin lost a lot of face, but in fact, it was because of this to ensure that the entire northern land was not affected by the border troubles of the Turkic invasion within a few years, and it was a substantial benefit!

Originally, after signing the covenant, Li Shimin could immediately return to Chang'an City to rest, but just in case, Li Shimin still waited until all the treasury property was delivered, and the Turkic army completely turned around and returned, before leading a group of generals to return to Chang'an, so it was delayed for a period of time, and during this period of time, Li Shimin was not in Chang'an City, but because he had already made all the arrangements before, Li Shimin believed that the defense of Chang'an City was impregnable. Even if he did not return to the city, it was so heavily guarded that even the entry of a fly would be immediately noticed—unless his men were negligent in their duties, which was impossible...... (To be continued......)

PS: Ps: Li Shimin: What kind of grudge do I have with you? You drove an excavator to scare me, and I was so scared that my spicy strips fell off!!

Tuli: You are rich and capricious, your necklace is more than 2,000, but you don't even give me 100 yuan......
