The Tang army advanced too fast, and in just a few days, it had already captured several other counties outside the Yanmen Pass. This was not only a very unfavorable thing for Yan Jun, but even Shi Yiqian, who was located on the side of Shengle City, couldn't help but lift his heart after hearing it. However, compared to the dispatch of the Yan army, there was not much movement on his side, but he only strengthened the defense of the adjacent places to the east of Shengle City and Yanmen County.

After all, he knew that this time Li Xin sent troops, and the main target was Yan Guo. Therefore, Shi Yiqian doesn't have to worry too much about his side.

Second, it is because relatively speaking, Shuofang County is a greater threat to the country. Now that Li Erhei is leading a large army to be stationed in that area, this is the most important thing for Shi Yiqian.

The news that Murong Ping, Li Hong and others rushed to the northern Daijun in the starry night was soon known by Li Xin. At this time, it had been four days since he had stayed outside Yanmen Pass, of course, he and some of the soldiers and horses were resting, but Shao Zisong and they did not stop there.

Among them, Shao Zisong stayed in Mayi County, and he will lead a part of the soldiers and horses to garrison there to guard against any movement in the northwest of Daiguo. After all, just because they haven't moved now doesn't mean they won't do anything in the future.

The rest of the army, under the leadership of Liao Chuan and others, bypassed Liuling Mountain to the east, marched east along Luoshui all the way, and recovered the hometown of Daijun.

The establishment of Daijun is very early, and the earliest time can be traced back to the Zhao State during the Warring States period. As for the Qin and Han dynasties, the system of counties and counties was formally established, and Dai County has always been an important frontier because it is located in the north and close to the Huns in the north.

In the era of the Western Han Dynasty, there were a total of 18 counties, but with the continuous change of the Central Plains court, the strength of the Central Plains regime became weaker and weaker, and the territory and population of this generation of counties were often uncertain. In particular, many of the county towns under its jurisdiction have been abolished and abolished, or they have moved south to other places.

So much so that by now, there are only a few southern counties left in Dai County. Especially in the northern part of Dai County, for so many years, they have basically been reduced to the horse grazing land of the Saiwaihu people, and the people are very small.

Therefore, even if the Yan army took these places, it always retained the system of the Jin Dynasty and did not restore the previous old county.

But for Li Xin, the meaning of this place is different. After all, no matter how the situation develops in the future, for a long period of time, this place will inevitably become a place of conquest between the Tang Dynasty and various ethnic groups outside the Saiwai, and its importance is self-evident.

Li Xin himself and Deng Qiang stayed in Lao County, and further east, if you pass through a mountain road, you can enter the territory of Pingshu County in Dai County. Although Murong Qian's army has been wiped out, there are still tens of thousands of Yan troops in Dai County who are holding on to the county seats.

In particular, the one that caught Li Xin's attention the most was the head of the Xiongnu He Lai, who had previously surrendered to the Yan State. There are more than 35,000 Xiongnu in his army, and if you deduct the old and weak, and according to the habit of all the people being soldiers, their strength is still not weak.

Since Murong Ke had already ordered them to obey Murong Ping's dispatch, unless He Laitou didn't want to follow Yan Guo, otherwise, he would inevitably concentrate some of his troops to go to Murong Ping to listen to the order.

With this time, the Yan State mobilized 50,000 troops from the counties of Youzhou, and if you add more than 10,000 soldiers and horses on He Laitou's side, the total number may reach 60,000 or 70,000.

It is especially important that Pingshu City is separated from Lao County and Fanqi County by only a mountain beam, and there is a valley in the middle for them to pass through.

If there is no defense in the county, when the time comes, Helaitou and them will come from the east, not only may the two county towns be gained and lost, but the eastward army is very likely to be cut off by them.

With Li Xin sitting here, in addition to waiting for news from Liao Chuan and his various departments, it is actually the meaning of monitoring He Lai's head.

"Your Highness, why don't we take advantage of Murong Ping's arrival to take down Dai County, Pingshu County, Guangchang County and other counties? If that's the case, wouldn't we be able to block the Yan army in the south of Taihang Mountain and let them not enter? Within the county office, Deng Qiang asked curiously.

Li Xin, who was looking at the map, raised his head and glanced at the generals standing on both sides below, and saw that most of them seemed to have this question, so he said: "You say, what are we going north for this time?" ”

Hearing this question, Zhang Hao said without hesitation: "Of course, it is to take Yanmen and other counties and expand the territory!" ”

His words have been recognized by many generals, of course, this is a matter on the surface, and everyone can see it at a glance. So, if you just say that, there's nothing wrong with that. But if it were that simple, Li Xin wouldn't have asked this question.

Therefore, after thinking for a while, Deng Qiang replied: "Although they are all recovering the counties in the Northland, in fact, the methods are different. Even the method mentioned before can be done. In this case, His Highness must have other considerations! ”

Now that the enemy's main force has not arrived, if you take this opportunity to take Daixian and other places, so that the Yan army cannot go north to support, it obviously seems to be easier.

"You're right! If we want to take all parts of Yanmen Dai County quickly, it is actually not difficult. But the question is, what happens after that? Don't forget, this place has been in the hands of Yan Guo for many years, and the big clans and even Hu people in various places here are basically closer to Yan Guo than to us. Things that are easy to get are always not easy to keep, and the best way to keep these places firmly in our hands is to let the people here see how strong and powerful we are. Li Xin nodded and said lightly.

"Subordinates understood! His Royal Highness's meaning is to show our strength through the defeat of the Yan army. If the Yan army is defeated here, it will not be so easy for the Yan army to recover its power here in the future. Moreover, even some of the powerful clans who have their hearts set on Yan Country do not dare to disobey our rule! Tu Qi suddenly understood.

"Yes! It is impossible to win what really belongs to us without a fight! There is no pie in the sky, and what comes too quickly is often lost very quickly! So, let's wait! Wait for Murong Ping to arrive here, and then let Yan Guo suffer another important blow. In this way, after this war, Yanmen Daijun and other places will be stable for a long time in our hands! "The words have been said so clearly, and the rest has to be understood by themselves.

Li Xin never believed that there would be things in this world that could not be earned, or that there would be things that were very different from the price and income. If there is, then obviously there is something wrong with it, and even if there is no problem for a while, it will inevitably manifest itself after a long time.

Therefore, he would rather use a war of blood and fire to strangle some possible future sprouts in the cradle, which is called prevention before it happens!

"Your Highness, Murong Ping will lead a large army to the territory of Daijun in a few days, but I don't know where it will come from. Shouldn't we be ready first? Liang Cheng asked.

Most of the counties in Dai County are located north of the Taihang Mountain, but some of them are located in the Taihang Mountain. Among them, several county towns such as Dai County and Guangchang County in the south are particularly important because they guard the Flying Fox and Puyin Ercheng in the west of the Taihang Mountains in the North China Plain.

After coming out of Taihang Mountain in the south of Daijun, it entered the boundary of Youzhou, and was connected with several feudal states such as Fanyangguo, Gaoyangguo, and Zhongshan Kingdom of Yanguo. In the northeast, Quang Ninh, Shang Gu and other counties.

Basically, if the soldiers and horses of the Yan Kingdom wanted to enter the territory of Daijun this time and fight Li Xin and them, there were only two roads to go from the south. Either take Zhongshan to cross the Flying Fox and enter the south of Dai County, or from Jicheng, after passing the military capital, pass through Shanggu and Guangning County, and go west along Luoshui.

If you look at the distance from the distance, it is natural to take the Flying Fox Road more quickly. Especially now that the southern part of Dai County is still under the support and control of Yan Kingdom, the Flying Fox is still very safe.

Moreover, as soon as he got out of the Flying Fox Pass, he entered the east of Pingshu County, which was a good thing for Murong Ping, because he would not be far from Li Xin at that time.

"With Murong Ping's character, if he knew where I was, he would definitely come straight to me. After all, as long as you take me, not only will you win this battle, but you will also be able to make great achievements! Therefore, he must be able to go to the flying fox! Of course, if Murong Ke came with troops, I am afraid that he would send troops from two directions! After thinking about it for a while, Li Xin said slowly.

"If that's the case, we'd better set up an ambush on its path first, and when it passes, we can take the opportunity to attack and destroy it in one fell swoop!" Deng Qiang proposed.

Li Xin understood what he meant, because after leaving the Flying Fox Pass, it was actually not far from the side of Lao County. Therefore, it is very likely that Murong Ping will lead the army to the west, first through Pingshu City, and then through the Qiyi Water River Valley, and then he can reach the city of Laoxian.

"The ambush is a good idea, but Murong Ping's army is coming, and it has a lot of troops, and the Qiyi Water Valley is too short to accommodate all of them. If we want to wipe it out in the first battle, I'm afraid it's unrealistic. Therefore, it is necessary to divide the troops, and our side must also divide two lines of soldiers and horses! Deng Qiang, you and Liang Cheng led 5,000 soldiers and horses to stay here, if it is not unexpected, Murong Ping will definitely send a group of soldiers and horses across the Qiyi River Valley, wanting to attack my rear. You wait here for the enemy to be annihilated! After Li Xinwei groaned, he ordered.
