Shi Qingyi's life in Luoyang is very peaceful. At this time, more than a year has passed since the battle of Emperor Tafeng, and that battle should have become a topic of conversation among people in the rivers and lakes, but I don't know why, it was covered up, little known, perhaps, because I was afraid of losing the face of the righteous path, after all, Cihang Jingzhai has always been the leader of the righteous path in the world, Jingzhai has suffered a loss, and the face of the righteous path is also disgraceful.

Li Shimin followed his father to Hedong, Shanxi, when the world has begun to be turbulent, the Hedong area of the group of bandits in chaos, Li Yuan served here, naturally has the responsibility to defend the land, so as soon as he arrived here, he immediately began to suppress the work of bandits, Li Shimin also actively participated in the army, to assist his father, he was a teenager, he liked to charge into battle, and did a detailed study of military affairs, and the opponent was only a thief who fell into the grass, so he won many victories, and with the extension of Li Shimin's time in the army, The generals in the army do not simply regard him as a brave and unscrupulous teenager, but feel that this young man's future prospects are limitless, so they pay more and more attention to him, this is the first time, Li Shimin is affirmed by his own value, so he is also very happy, and he has become more and more diligent in the work of suppressing bandits. So much so that he often took the lead when he rushed into battle, although he was often able to win, but it also made his father Li Yuan very troubled.

In the past three months, Li Shimin's father and son often sent a letter to their home within a few days, Li Yuan of course wrote it to Mrs. Dou, but Li Shimin was varied, his brothers and sisters, relatives and friends, even Shi Qingyi did not miss it, because it was a private message, others did not know the content, so many people wanted to start a serious life because the two had reconciled. And every time, Shi Qingyi will also carefully write a reply letter, and then send it back. This undoubtedly deepened this idea of most people, except for one Li Xiuning who is still insisting and swearing that the second brother will not like this second sister-in-law, others obviously don't think so, so their isolation of Shi Qingyi has been slowly eliminated. I don't know if it's good or bad.

In fact, what is written in the letter, in fact, it is just the use of some military strategies in the field, Li Shimin is actually very proficient in the art of war, but even the most outstanding generals, in fact, can not do without the help of good staff officers, after the debate at the gate of the Li family, Li Shimin obviously thinks that Shi Qingyi barely has the qualifications to be a staff officer, so he will write a letter to Shi Qingyi to discuss his recent thinking on war strategy. Shi Qingyi answered them one by one, and then sent them back, although it was not necessarily correct, but it was her own thinking, and then, the correspondence between the two people gradually increased, which caused the misunderstanding mentioned above.

Shi Qingyi knows that Li Shimin is not his opponent now, but once he really encounters actual combat, he is a horseman, the one who can only flee for his life, but he can't take care of his subordinates. But fortunately, it's not Zhao Kuo, Shi Qingyi's mentality is very optimistic. Originally, she focused on the art of war and war just because of her interest, that is, she didn't have the ability to be a general, and she didn't have the heart to be a general. Being alone and obscure is Shi Qingyi's nature, sticking into the pile of people and being a dazzling figure is not what Shi Qingyi should do.

In July, Emperor Yang hunted in the north and led the crowd to inspect the north, although the banner is clear, the team is huge, and it is still a posture of the Heavenly Empire, but the discerning people can see that the external strength and cadres that cannot be hidden in this team, and many clear-minded ministers have a bad premonition in their hearts. The emperor triumphantly went on the road, and under the sky of Luoyang, there was a trace of haze.

In August, Li Shimin sent a letter as usual, Shi Qingyi opened it, and found that the content inside was to ask how to win more with less, and defeat the strong with the weak. Is it okay to win more with less, and to defeat the strong with the weak! Shi Qingyi shook his head secretly, he was already on the weak side, on the defensive, and he had to win against the strong side, then, it was impossible to fight head-on, and he would lose against him. Soldiers, treacherous! If you want to be able to use tricks, the first thing you need to do is to find the weaknesses of the opponent, if the opponent is solid and has almost no weaknesses, then it will be difficult to use tricks. Shi Qingyi once saw a military book that said: If you want to win, then you must have enough understanding of the enemy's generals, no one is perfect, everyone has a weakness that he can't overcome, and if you can find this weakness, then you will be half the success.

Of course, if your opponent has almost no weaknesses, his camp is solid, his army is neat, and the morale of the army is strong, then you should not be discouraged, although he is not easy to be defeated, but such a general must be biased towards steady and steady battles, so if you can successfully deceive him, let him think that the frontal enemy is very strong and not easy to deal with, then he will not attack you lightly in order to preserve his strength. In this case, even if you can't defeat your opponent, you can still protect yourself.

Shi Qingyi sorted out the things he thought of, and then wrote them into the letter and handed it to the servant who had been waiting for the letter next to him, the servant seemed to be in a hurry, saluted Shi Qingyi, and left in a hurry. It's very abnormal, Shi Qingyi was a little puzzled, he didn't know what kind of medicine Li Shimin was selling in his gourd, maybe it was to make a bet with others. Shi Qingyi thought to himself. She didn't know that what Li Shimin was about to face at this time was a war with a huge disparity in strength and almost death.

A few days later, a proclamation reached Luoyang, and suddenly the world shook, the Turkic Shibi Khan had rebelled, and led hundreds of thousands of troops to kidnap the Son of Heaven, who had now retreated to Yanmen, surrounded by the Turks, and urgently ordered the army of the King of Qin in the world to rush to the rescue...... Wang Shichong, the eunuch of Luoyang Palace, armed all the young and strong people in the palace and led them to the Yanmen battlefield, and it is said that he wept day and night for His Majesty's comfort, and I don't know whether it was true or not, many ministers also mobilized, and put together an army that was about to rush to Yanmen to fight.

For these patchwork troops, Shi Qingyi scoffed, the complete ragtag army is not the opponent of the Turkic cavalry that comes up and down the grassland like the wind, and going to Yanmen is completely to send them to death, and it will deal a huge blow to the morale of the Yanmen defenders who are still struggling to support, what will Shibi Khan think when he sees that the Sui army is so vulnerable? Perhaps he would continue to besiege Yanmen on the one hand, and command a cavalry to enter the hinterland of the Central Plains on the other, which would be the worst situation. Li Shimin, when the time comes, how should you do it?

Thinking about the unusual letter a few days ago, Shi Qingyi understood that Li Shimin must have been on the way to Yanmen, Li Shimin was not a guy who could settle down, and if he still had the idea of his cousin in his heart, then this was really a great opportunity, if he missed it, there would be no next time. Even soon, it may have approached the frontier and converged with the local frontier generals.

Shi Qingyi thought well, Li Shimin received an edict in Hedong, borrowed more than 100 elite cavalry from Li Yuan, ran all the way, and soon met with the troops of Yun Dingxing, the general of the Tun Guard, Yun Dingxing's soldiers were few, and they were moving slowly because of the fear of the enemy, Li Shimin then presented a suspicious soldier's record, Yun Dingxing adopted Li Shimin's opinion, and ordered the soldiers to put more flags during the day and raise more torches at night, stretching for dozens of miles. At the same time, he accelerated the pace of the march and made the illusion that reinforcements had arrived, hoping to scare off the retreating Turkic troops.

"The Turks are divided into more than 100 tribes, large and small, although Shibi Khan is the nominal leader of the Turks, but all he can control is his own line of people, and the other tribes will not be of the same mind as him, and will not make the determination to fight to the death with us. Li Shimin said to Yun Dingxing. Yun Dingxing also thought that Li Shimin's analysis was very reasonable, and they marched all the way, entering Xinkou in Shanxi in early September, and getting close to Yanmen.

It was at this time that the outpost battle began, and Li Shimin believed that in order to convince the Turks that the Sui Dynasty's reinforcements were really coming in large numbers, then it was necessary to take the initiative and use a series of skirmishes to suppress the nerves of the Turks. So, Li Shimin took the initiative to ask for help, borrowed hundreds of elite cavalry from Yun Dingxing, plus his original cavalry, formed a forward, and accelerated his speed to Yanmen, and Yun Dingxing commanded the remaining sergeants to temporarily stop the march, set up camp, and at the same time extended the flag and fire to the two wings, making it look like reinforcements were constantly arriving, and they would immediately launch an attack after a little rest. Reinforcements could not have arrived so quickly. Soon, the scouts kept coming with news: a Sui Dynasty cavalry of hundreds of people was rushing towards Yanmen, it was estimated that it was the outpost cavalry of the Sui Dynasty reinforcements, and it had already fought with the scouts on the periphery many times, and it was obviously the elite of the Sui Dynasty.

Things have come to this point, even Shibi Khan began to waver, continue to besiege the city, Yanmen can not be attacked for a long time, and the Sui Dynasty's reinforcements have arrived, and the Sui Dynasty's army has a head-on confrontation, Shibi Khan did not have such preparations, after all, the Turks after the Sui Dynasty for many years of strategy, the strength has long been much inferior to before, the grassland tribes have a sense of awe for the Sui Dynasty, although the Shibi Khan dared to surround the Son of Heaven, but also took advantage of the opportunity of Emperor Yang's northern tour, and did not dare to enter the Central Plains, now the reinforcements have arrived, The pressure on Shibi Khan can be imagined. It's just, is that really the reinforcements of the Sui Dynasty?

Shibi Khan thought about it again, "Order the army to increase the manpower of the scouts and go all out to round up those outposts of the Sui army, I want to know whether they are real or false, and how many of them there are." Shibi Khan said viciously.

Li Shimin and Ma Sanbao sat on the hill to rest, and at the same time swallowed the military rations, Ma Sanbao was a servant of Chai Shao's family, but he was alert and smart, and he trusted Li Shimin, so he asked for it from Chai Shao to be his own hand, and this time he also took him to the battlefield with him. The continuous battles made them tired, and even when they were sleeping, they had to beware of the sudden appearance of the enemy, since leaving the Xinkou Pass, after the elite cavalry stood out, it was a daily non-stop encounter, the Turkic scouts, and the light cavalry of the Sui Dynasty, constantly chasing and fighting. Hou Junji appeared in front of the two of them: "Shimin, we have been fighting around here for nearly two days, and the enemy still has not retreated, on the contrary, the cavalry rounding up us is gradually increasing. Hou Junji is also an old man in Li Shimin's Luoyang circle, the two of them are acquaintances who can't be more acquainted, Li Shimin drank a big sip of water again, and then exhaled comfortably: "It doesn't necessarily mean that he saw through our strategy, or he may be unwilling, so he wants to catch us and understand the reality of our army." Unfortunately, we would never give him such a chance. Li Shimin said, Hou Junji frowned when he heard this, "But now the most critical thing is not us, nor Shibi Khan, but the emperor trapped in Yanmen, Yanmen has been surrounded for nearly a month, and the situation inside must be very critical." Because of anxiety, Hou Junji's words had some impatience, Li Shimin smiled disapprerovingly: "In fact, it's not just Yanmen, we are also very anxious, the army is encamped, but it doesn't move for a long time, it will definitely make people suspicious for a long time, I believe that at most ten days, if the army fails to make a move within ten days, our bluff will be seen through by them." Before Hou Junji showed a frightened look, Li Shimin had already walked in front of him and patted Hou Junji on the shoulder, "Are you willing to do a desperate thing with me?" Looking at the firmness and fanaticism in Li Shimin's eyes, Hou Junji thought that Li Shimin must have made a decision in his heart, so he said: "Of course I do." "Good brother!" Li Shimin smiled, "Let's take a day off today, and tomorrow, we will do a big job." ”

The next day, at midnight, at this time, in addition to the army of the vigil, most of the Turks have gone to sleep, but under the influence of the Sui Dynasty reinforcements that are close to the end of the time, the quality of sleep is greatly inferior to before, Shibi Khan turned over and transferred to the past and couldn't sleep, the enemy put too much pressure on him, think about it, the army of the Sui Dynasty is about to kill from Xinkou Pass immediately, his heart is unwilling, why, why will the reinforcements arrive so quickly, as long as a few days, the Son of Heaven in Yanmen County must already be in his own bag, Unfortunately, with the arrival of reinforcements, this seemingly imminent goal has also come to naught, and it is too close to reach it. Shibi Khan's heart was filled with anger.

Suddenly, there was an earth-shattering noise outside the big tent, and countless fires suddenly lit up in the dark night sky, and the chaotic and noisy sound filled the entire Chinese army camp, and the enemy attacked! Shibi Khan immediately reacted, this is the enemy took advantage of the night, attacking his own Chinese army, he immediately got up, rushed out of the camp tent to command the battle, out of the camp tent, only to find that there was a mess outside, a cavalry of I don't know how many men and horses killed into the camp, is quickly killing people and setting fire, they will leave with one blow, never drag mud and water, the panicked Turkic soldiers can not stop them at all, they rushed through.

The leader of the team is undoubtedly Li Shimin, after resting for two days and one night, after raising enough manpower and horsepower, Li Shimin issued an order to everyone to attack at night, at that time, including Hou Junji, Ma Sanbao, everyone was taken aback, with hundreds of people to impact hundreds of thousands of Turkic battalions, it can almost be said to be an impossible task, although it is said that the night operation, can undoubtedly increase the coefficient of success, however, night battle, has always been the most unwilling battle for all soldiers and generals, almost invisible in the night, Relying on his voice and his own vigilance, once the accident happens, there is almost no room for maneuver, although Hou Junji is prepared, he still never thought that Li Shimin would have such a bold plan.

It's not about wisdom, it's just a decision of courage, it's just a question, do you dare! Li Shimin strained his face and said loudly to the soldiers: "In the past, Wei Wu Cao Cao went south to the south of the Yangtze River and wanted to annex the Jiangdong Sun Quan Group in one fell swoop, and Sun Quan's general Gan Ning only led more than 100 horsemen to dare to attack Cao Ying at night, and no one died, how can the current Turks compare to Cao Cao, the Emperor of Wei Wu back then!" Moreover, we now have three hundred, are we not as good as the one hundred in Ganning? Answer me, Are you not as good as them!! Angered by Li Shimin's words, more than 300 cavalrymen suddenly shouted: "Of course not! So, Li Shimin led this team of cavalry that was stimulated by enthusiasm, and took advantage of the night to brazenly pounce on the camp tent of Shibi Khan.

The Turks are nomadic people, so the camp they established is also very simple, and because of the majority of cavalry, the camp has left a runway for cavalry, but now, it is cheaper for Li Shimin, and it has become a fast passage for them to kill the enemy wantonly. Li Shimin held the famous bow in his hand, and Zhang Xian took an arrow, and whenever there was a place where a general gathered soldiers to resist in formation, he shot an arrow. All of them were hit, and the leader died, the soldiers had no backbone, and naturally the soldiers had no fighting spirit, and fled in all directions, and in this way, this army rushed all the way to kill, and was not effectively blocked, until the camp passed, and many Turks did not react. Ma Sanbao and Hou Junji were concentrating on protecting Li Shimin, who kept shooting arrows, while opening the way ahead, and when they rushed through the camp, both of them were also a little stunned, they didn't expect that they could actually rush through the enemy camp. Go back, kill for a while. The two tacitly turned back to their horses, and they were about to lead the army to charge again. "That's enough, Junji, Sanbao, let's go." Li Shimin hurriedly said, stopped them, and did not wait for the two to refute, but just urged them to leave quickly, although the two did not understand what Li Shimin meant, but they absolutely obeyed the order, took the soldiers, and left immediately.

Running all the way, when dawn, everyone had already left the camp of the Turks for dozens of miles, everyone was relieved, dismounted and rested, this time the camp, no one died, no one fell behind, but a few soldiers were injured by different Cheng dù, just a night of running and fighting, whether it was a man or a war horse was already exhausted. Only then did Li Shimin stop Hou Junji and Zhang Sanbao, and told them the reason for the dissuasion: our number is too small, and being able to successfully charge the camp at one time is to take advantage of the enemy's unpreparedness, and now the enemy has been awakened by us, and there is a danger of being trapped in the second charge, once we fall, then through our confession, the enemy may know our truth and truth, then everything we have done before will be in vain, Yun Dingxing has too few troops, and can only stick to Xinkou, but the Turks can attack the city with peace of mind. In that case, Yanmen will be really in crisis. Hou Junji was in a cold sweat behind him, and he realized how reckless he was at that time, and he almost lost his life, but Ma Sanbao was full of dissatisfaction: "If we kill once, it is estimated that we will be able to get the head of Shibi Khan." In that case, the enemy will be leaderless, and it will be time to retreat. Li Shimin smiled and patiently explained to him: "Shibi Khan is the leader of the Turks, and the guards around him must be the elite of the Turks, although we took advantage of the sneak attack, it is still very difficult to kill the Shibi Khan, and the Turks are different from us, they are a nation and respect the strong." Li Shimin paused, "If Shibi Khan is killed by us, the throne is likely to be inherited by his younger brother Jieli, in that case, since the enemy knows our truth and has a strong leader, they will continue to besiege and will not withdraw their troops." Therefore, maintaining the illusion and terrifying their hearts is the best choice for us. Only then did Ma Sanbao understand, admired it in his heart, and at the same time patted his ass slightly: "In the end, it is Li Valve's second son, not comparable to those of us subordinates." Li Shimin looked at him with a smile: "Sanbao, if you can also read more books, then you can also understand these." Ma Sanbao had a bitter face: "Childe, you don't know me, read the book, you might as well let me go to the Turkic camp again!" Hou Junji next to him, Li Shimin and a sergeant, couldn't help laughing when they heard it.

In the camp tent of Shibi Khan, a group of large and small military generals quarreled all over the world, last night the Sui army actually took the opportunity to rob the camp, although the loss was not large, but this exposed a very strict problem, that is, the Sui army is about to start an attack, for the decisive battle with the main force of the Sui army, most people are not so prepared, originally, the hijacking of the Son of Heaven is the hijacking of the Son of Heaven, since the Son of Heaven obediently sent to the door, it would be too sorry not to laugh at himself, but since Yanmen has not been down for a long time, there is a danger of war with the Sui army, Although most of the nomads on the steppe are not very good at arithmetic, they can still distinguish between taking advantage and suffering. And among them, who belonged to the younger brother of Shibi Khan, Jieli's attitude was the most intense: "Great Khan," Jieli persuaded bitterly, "the enemy's reinforcements have arrived, and the gains outweigh the losses when they are besieged...... Not to mention that the army is not able to fight now, even if we win by luck, then our strength will be greatly damaged, and the struggle with the Western Turks will be at a disadvantage at that time. In the face of more and more opposition from people, Shibi Khan became more and more powerless to suppress it, but he still wanted to take a chance and wanted to delay, "The enemy did launch a night attack, but in terms of numbers, it was only a few hundred, not much. Jieli immediately retorted: "In the past, Wei Wu Cao Cao went south and fought with Sun Quan in Hefei, and Gan Ning attacked Cao Ying at night, and there were only 100 people. More generals began to echo Jieli, the enemy's night attack can only be said to be a precursor to war, if you don't retreat, I'm afraid that you will really have a hard battle with the reinforcements of the Sui Dynasty.

At this time, a Turkic soldier stumbled into the camp tent: "Great Khan, the big thing is not good, the Western Turks have already taken the opportunity to call over when they see that my old camp is empty." As soon as these words came out, there was an uproar in the camp tent, and Jieli immediately bowed to the ground: "Please Da Khan quickly retreat and rescue the old camp." A group of generals also asked for orders: "Please retreat from the army and rescue the old battalion!" Shibi Khan's face was terrifying, he stood there, not saying a word, but he knew that the current situation was beyond his control, and everything was out of his control, he gritted his teeth, and finally squeezed out two words: "Retreat!" The generals in the camp received the order, and immediately rushed out of the camp to go back to organize the soldiers and horses, but they were not willing to wait for a moment. When Shibi Khan saw this scene, he only felt a burst of coldness in his heart. He knew that after this battle, his prestige in ** had been almost accompanied.

Shibi Khan didn't think that it was a fake news sent by Princess Yicheng in the old camp, but he also knew that this was not the most important reason, Sui's reinforcements had arrived, which was the main reason why the soldiers were afraid of not fighting. So, the Turks packed up and immediately retreated from the battlefield.

The battle of Yanmen, from August 13, to September 15 Turkic retreat, lasted more than a month, the Son of Heaven was preserved, however, due to the loss of face in this incident, Siyi lost the awe of the Great Sui, from then on, the border pass began to be attacked by a small number of people, the offensive and defensive momentum changed hands. It was not until more than 20 years later that the newly established Tang Empire made an expedition to the north of the country and regained its dominant position over the ethnic minorities in the north.

Although Li Shimin was outstanding, but he did not receive much praise, the public opinion at that time believed that it was the great help of Princess Yicheng to relieve the crisis, for this, Li Shimin also felt that it was taken for granted, after all, he was just a weak crown boy under the age of twenty, although he was able to maintain the momentum of the landslide in front of the soldiers, but his heart was a little uneasy after all, and he tossed to the end, he failed to scare Shibi Khan, so he didn't care much about the credit, On the contrary, he was elated because of his first experience in the battle formation. It's just that when the meritorious deeds were rewarded after the war, Emperor Yang of the Sui Dynasty was angry again, "the promise is quite heavy, and the reward is too thin," so the meritorious soldiers were angry in their hearts, and the people's hearts have been lost since then. But this is no longer Li Shimin's business, and the young man at this time is excited about his victory with the northern nomads. So, he took his friend Hou Junji and a group of generals back to Shanxi, where his father was, and wrote a number of letters, asking Hou Junji, who was going to return to Luoyang, to bring to his relatives and friends in Luoyang City to show them his achievements.
