At that time, Li Shimin had General Wei Chigong by his side, which is now one of the gods of the left and right doors.

Wei Chi Gong saw that this Chang Yan had just come to ask for credit, and he was very unhappy in his heart.

In the next few years, the Tang Dynasty crusaded against foreign tribes, and Chang Yan and Wei Chigong both showed their skills, and the two invited countless merits in front of Li Shimin and killed thousands of enemies.

Li Shimin sent his soldiers and horses and did not want food for the soldiers, and only took the 800 brothers around him to kill the enemy, creating many good achievements.

Li Shimin saw that Chang Yan's ability was extraordinary, so he secretly made a decision.

Due to the countless tribal groups outside the Tang Empire at that time, there were even rumors that the tribes outside the Tang Dynasty were going to unite to capture the Tang Dynasty, which has always become Li Shimin's heart disease, although the strength of the Tang Dynasty is undoubted, but I am afraid that the more I think about it, the more I think about it, the more I will become a hurdle in my heart, and if I can't get over, I will be exhausted and emaciated.

Li Shimin had long wanted to get rid of this heart disease, but if Wei Chigong, who was guarding the border pass, was transferred to attack the front line, then the enemy would soon take advantage of the lack of support in the rear.

At this time, there is a common secret, why not use it!

Thinking of this, Li Shimin summoned Na Chang and asked him to lead his troops to fight with Na Xue Yantuo and get rid of this piece of heart disease.

Of course, Chang Yan thought in his heart, if this achievement is completed, then he will be above ten thousand people under one person! When the time comes, don't talk about the ministers of the DPRK and the Central Committee who are secretly pointing at him, even the general who protects the country, Chi Gong, will have to be respectful to him, and the day of his emergence is just around the corner!

Chang Yan has always been dissatisfied with the title of this Tianmu general, after all, there is also a Wei Chigong who is on an equal footing with him, and he wants to be the only one.

This night, Wei Chigong heard that Li Shimin was going to give Chang Yan a chance to be promoted, so he came to the palace in a hurry and asked Li Shimin for comment.

"I am loyal to the Tang Dynasty, why should I give this opportunity to punish Xue Yantuo!" Wei Chigong ignored the eunuchs and maids in the palace and the two ministers who wrote the book, and asked Li Shimin angrily.

Li Shimin was sitting on the imperial chair, frowning with his hands folded.

"Bold Wei Chi Gong, how dare you not kneel when you see King Tang!" The old slave beside Li Shimin said angrily.

Li Shimin waved his hand to signal Wei Chi Gong to avoid kneeling, closed the fold, supported his robe and went down, and said to Wei Chi Gong: "Chi Gong, you have the mission of the Tang Dynasty, you must not leave the rear easily, and when he stays until the other day, I will have a great task entrusted to you!" ”

But that Wei Chi Gong didn't listen at all, and before Li Shimin's words fell, he had already given up his hand, and then walked away.

The place where this lieutenant Chi Gong went was the camp where he was always stationed in Biansai.

The Xue Yantuo in Li Shimin's mouth was actually a nomadic tribe in the north in the early Tang Dynasty, and its customs were similar to those of the Turkic tribes.

Xue Yantuo once took advantage of the weakness of the Turks, broke the Jieli Khan, and his strength skyrocketed, and he began to have a disobedience to the Tang Dynasty, and the son of his leader planned to set up 200,000 elite soldiers to attack the Turks, and then he wanted to take advantage of this to attack the Tang Dynasty.

Xue Yantuo's tribe is very interesting, although it is a nomadic people, but it has repeatedly conquered the surrounding tribes with foot warfare, so before the large-scale invasion, its domestic troops first trained to learn the method of foot warfare. With five people as a unit, let an experienced leader keep the horses of the five people, and the other four people will rush forward in battle, and once they win, they will immediately pursue on horseback. If the horses are not received in time, their families must be punished as slaves and rewarded to the foot soldiers who are fighting in front.

Before Chang Yan, Li Shimin had assigned the generals of the border plug to intercept Xue Yantuo, who was also dominated by cavalry, and there were many men and horses generously, and it was a foot battle, and they fired arrows together, wounding most of the horses, causing most of the cavalry to lose their impact.

At this time, the situation is extremely critical, with a few blows, the first vassal troops were defeated first, and most of the main forces lost their horses, for many generals, it was already a defeating situation, sure enough, after several rounds of the war, the Tang Biansai was defeated by the Xue Yantuo tribe and retreated, and finally retreated to the dividing line between the border and the border, if you give up a step further, I am afraid that this Xue Yantuo will enter the city.

The battle between Xue Yantuo and the Tang Dynasty was delayed for five years, from the early stage of course not being allowed to being defeated repeatedly, every time the news came from the front, Li Shimin's heart was heavy, in vain I was so rich in the Tang Dynasty, but I was unable to compete with Xue Yantuo.

In the next two years, Li Shimin has been mobilizing troops and dispatching generals, and constantly mobilizing famous generals in the rear of the border plug, but they are all defeated.

For five years, Li Shimin and the generals have not found a good way, seeing that the movement of the rear has been seen through by the neighboring countries, as if the weakness of the Tang Dynasty is naked in front of the front and back, and it is about to be broken.

In fact, what they didn't expect was that this was a newly organized infantry battle to suppress the surrounding nomads, but on the other side, it was a Han people who had played thousands of years of foot combat tricks and were forced to manipulate their old professions, and the two sides used infantry tactics to compete with each other, and the results were really not difficult to imagine.

The border fortress is steep and abnormal, and there are many Gobi, and the nomadic guerrilla war will be defeated and fled.

Fortunately, a few years later, such a number one person emerged in Middle Earth, and for Li Shimin, it was a gift from God to save the Tang Dynasty.

That's why Li Shimin gave this opportunity to Chang Yan.

Li Shimin thought so and looked at the back of Wei Chigong leaving the palace.

Besides, the lieutenant Chi Gong galloped to the camp where the guards were often secreted by himself, and when he looked at it from a distance, the camp was pitch black, the torches had never been seen, and the sentry had never been seen.

Wei Chigong blew his beard, the enemy is so light at the moment, how can he be a general, he bent down and dismounted, and walked towards the camp on the yellow earth stuffed over there.

But when he got closer, he found that there were no torches or sentry posts in the camp, and there was not even a single person to be seen, and there were no boilers and scoops for cooking on the ground, nor shelves for cooking food, nor mountain objects for feeding his hunger.

There was only one lonely tent in the camp, and on the opposite side was the station of the Xue Yantuo people stationed in the border fortress, and the two places were only separated by a perch river, if the other party attacked the camp at this time, then within one night, the people in the city near the border fortress would suffer.

The camp side is slightly brighter than the lights on Xue Yantuo's side, and with the bright moonlight, there is a little white light in the camp, Wei Chigong stood at the back of the camp and looked at Xue Yantuo, and the whole camp was only the moonlight swaying his lonely back.

When Wei Chigong saw this, he couldn't help but be angry, the Holy Lord gave you the task of guarding the border fortress, but you didn't know where to go, and you neglected your duties!

Wei Chigong's jealousy suddenly rose to the top, and he clenched his fists and walked towards a huge tent.

Because the tent of the commander of the general of the general of the general of the general will be in the rear of the whole camp in the middle of the night, so that if there is an invasion of a foreign enemy country in the middle of the night, the abnormal noise can wake up the rear, and the tent of the main general is wider than the tent of the soldier, so Wei Chigong can recognize the place where he sleeps at a glance.

But when Wei Chi Gong lifted the corner of the account and looked inside, it made his hairs stand on end, and he gasped————

The huge tent, which should have only one main general, was neatly filled with people, without a trace of breath, no one snoring, and not even a person's chest lying together because of their breathing.

Wei Chigong shivered all over his body, and the cold was transmitted from this big tent to his body, as if he had entered an ice cave.

Wei Chigong stood outside the tent and stared for a long time, looking for Chang Yan's location, but he didn't see it.

Maybe it was too dark in the big tent, and Wei Chi Gong pressed the cold knife on his waist with his hand, ready to respond to the enemy at any time, because in his thoughts, these soldiers in Chang Yantuo's hands might have been attacked by Xue Yantuo and died.

Otherwise, how can a living man sleep without panting?

Thinking like this, Wei Chigong walked inside, and while getting down, he inspected the faces of these people lying on the ground, although he didn't count how many people were in this big tent, but the dense head and feet made it difficult for him to move an inch, he stood on tiptoe and stared at their faces as if they were sleeping, but he couldn't see clearly.

In this way, he was about to walk behind the short screen in the big tent, if it was made by Xue Yantuo and those people, then I am afraid that there would be an ambush behind this short screen!

Thinking of this, Wei Chigong gently pulled out the cold knife hanging diagonally on his waist, slowly walked to the screen, and then twisted his right foot to appear.

When he looked at the tiger skin square seat (the main general's couch) behind the screen————

But he saw a person sitting precariously, the darkness covered his face, and at this time, he was facing Wei Chigong who appeared from behind the short screen!
