The Zhao army has not launched an attack on the Yan army, and the prince Dan is relieved, but Fan Yuzhi's heart is nervous. Because Zhao Jun's behavior was too abnormal, the front army that had just defeated the Yan army rushed over, but he didn't attack the Yan army, so he was consumed with the Yan army, which was indeed a very abnormal behavior. When Fan Yuzhi was in the Qin State, he was a general alongside Wang Jian, Meng Wu, and Huan Qi, experienced in a hundred battles, and proficient in the art of war, of course, he knew that if the enemy's behavior was abnormal, then the enemy must have other plans.

Sure enough, on the fourth day, the Yan army received the news that the rear army of the Yan army was attacked by the Zhao army, and the 20,000 army lost more than 10,000, and all the grain and grass materials escorted were also looted by the Zhao army.

It turned out that the plateau knew very well that the Chinese army led by Tai Xiaodan also had 50,000 troops, and if he defended with all his might, it would not be easy for him to break through the defense line of the Yan army, even if he broke through the Yan army, but his own losses would not be less, so the plateau decided to fight the rear army of the Yan army first, and then turn around and deal with the Chinese army of the Yan army. In this way, it can also cause a flanking attack on the central army of the Yan army.

So Gao Yuan ordered Huang Chong to lead 30,000 soldiers to confront the Chinese army of the Yan army and drag the Yan army. He joined forces with Zhongsun Qibu, led 5,000 cavalry troops, 5,000 infantry troops, and the infantry were all equipped with war horses, bypassing the middle army of the Yan army and directly attacking the rear army of the Yan army.

Although the rear army of the Yan army also had 20,000 people, they were all old and weak soldiers, and they were also escorting a large amount of grain and grass materials, of course, it was impossible to withstand the impact of the cavalry of the Wu'an army, and as a result, they were killed by the Wu'an army at once, so they had to throw down the grain and grass materials and flee in all directions. Therefore, this time he fought behind enemy lines, and Gao Yuan also ordered that no prisoners should be captured, and if they could be killed, they would be killed, and if they could not be killed, let the Yan army run away. Of course, they could only let the Yan army flee in the direction of Juyongsai, but they were not allowed to join the Chinese army led by Prince Dan.

As a result, nearly half of the 20,000 Yan troops were killed and wounded, and the remaining Yan troops fled back to Juyongsai, so Tai Xiaodan did not receive the news that the rear army was broken, and he was still stupidly fighting against the Wu'an army led by Huang Zheng.

And after receiving this news, Tai Xiaodan and Fan Yuzhi were stunned as if they were hit hard. After the rear army was defeated by the Zhao army, not only did it lose all its food and grass materials, but even the way back was cut off by the Zhao army, and it fell into the cause of the front and rear attacks. Moreover, the food in the army is only enough to support four or five days, and there is quite a situation of the battle to Changping.

After a long while, Tai Xiaodan came back to his senses and said, "General Fan, what should we do now?" ”

After all, Fan Yuzhi has been in battle for a long time, and he quickly stabilized his feelings, calmed down, and said: "Prince, don't hesitate now, our food is only enough to support four or five days, and we must not stay here and consume the Zhao army hard, we should immediately organize elite soldiers to break through the siege, only by fighting out of the encirclement, can we escape a way out, otherwise we will only end up with a Zhao Kuo." ”

At this time, Prince Dan was already the master of the six gods, of course, all listened to Fan Yuzhi, so according to Fan Yuzhi's construction, only 10,000 soldiers were left to garrison in the battalion, and he and Fan Yuzhi led the other 40,000 troops, 400 chariots, and launched an attack on the Wu'an army in the plateau.

After defeating the rear army of the Yan army, Gao Yuan also calculated that Tai Xiao Dan would definitely concentrate his forces to break through and open the passage to escape back to Juyongsai, so he also arranged guards on the retreat of the Yan army. Of the 5,000 infantry troops he brought this time, 3,000 were Beiwei troops, which could form one hundred and fifty Mandarin Duck Formation squads, which were also used to block the main force of the Yan army.

The movements of the Yan army have always been closely monitored by the plateau, so as soon as Prince Dan and Fan Yuzhi sent troops, the plateau received the news and immediately ordered the formation to be set up to meet the Yan army.

The location of the plateau is a three-fork intersection, a traffic artery, about 100 meters wide, with hillside forests on both sides. This area is mostly mountainous, so it is already very good to have such a site as a battlefield, after all, the plateau is to block the Yan army, and it is impossible to wait for the Yan army in a large flat and open area.

With a distance of more than 100 meters wide, about fifteen Mandarin Duck Formation squads can be arranged, and the depth of Mandarin Duck Formation combat is usually three columns, a total of forty-five Mandarin Duck Formation squads. On the plateau, thirty mandarin duck formations and five hundred soldiers were arranged on the slopes on both sides, and the cavalry was hidden in the mountains and forests, and the rest were all used as reserve troops.

At this time, the Mandarin Duck Formation also had further development, but it was not just fifteen people fighting as a unit, but it could become a team of nine, five, or three people according to the different battlefield environments. In addition, there is also a change of heavy dà, that is, the wolf cage has been created.

Originally, the wolf cage is actually a kind of big bamboo in the south, with a lot of branches and branches, just like a big bamboo broom, but the wolf cage soldier is a Guan Jian weapon that forms the Mandarin Duck Formation, and it is also an indispensable weapon when the Mandarin Duck Formation changes into a team of nine people, five people, and three people, because the coverage of the wolf cage is very large, which can fully limit the enemy's activities and cover their companions.

In the past, the plateau was used to replace the wolf cage soldiers, and the actual effect was much worse, after occupying the county, the plateau also drew a figure and created a wolf cage, which was actually mainly wooden, and the front end was nailed out of a lot of forks and forks, and a sharp iron was inserted at the tip. It looks like a big fan. And after creating the wolf cage, the power of the Mandarin Duck Array has also increased by another level. Today is also the first time that the upgraded Mandarin Duck Formation has played.

Seeing that the Wu'an army had already lined up the array, Fan Yuqi and Tai Xiaodan also commanded the Yan army, and set up the array about 300 steps away from the Wu'an army. Although Fan Yuzhi has always been very concerned about the movements of Zhao Jun, but the information communication in this era is not smooth, and it is impossible for Fan Yuzhi to inquire about the situation of the Wu'an Army, so after seeing the array of the Wu'an Army, Fan Yuqi was also very surprised, because the array of the Wu'an Army is indeed too unconventional, not to mention the loose queue, there is not even a chariot, although Fan Yuqi also knows that the Zhao Jun has always been good at using cavalry and rarely uses chariots, but it is not that there is no chariot. Even when Li Mu resisted the Xiongnu in Daijun, there were more than 1,000 chariots.

But Fan Yuzhi did not dare to despise this Wu'an army, after all, before this, the Wu'an army's flexible and unpredictable tactics showed that the commander of the Wu'an army was extremely good at using troops, and he was not necessarily under Li Mu back then, so he would never make such a low-level mistake. It must have other intentions, and I didn't see it. So Fan Yuzhi immediately ordered a hundred chariots to go into battle and storm the defense line of the Wu'an army.

It should be said that Fan Yuqi's tactics are really good, because the chariot still has a considerable advantage over the infantry, and it is used to impact the infantry queue, which is very effective, of course, Fan Yuqi also has a little bit of a test of the Wu'an army's reaction.

As soon as Fan Yuzhi gave the order, a hundred chariots immediately crossed the line and charged towards the Wu'an army.

The war horses galloped, the wheels rolled, and there was a rumbling sound, although there were only a hundred chariots, but because the width of the battlefield was limited, only seven or eight chariots could be walked side by side, so the entire array was also very long, close to three hundred meters, and the momentum was quite terrifying.

And at this moment, in the array of the Wu'an Army, the soldiers of the first two rows of Mandarin Duck Formation squads all knelt on the ground, only the crossbowmen stood, and at this time, they had all put their arrows on their own, and each Mandarin Duck Array squad was equipped with two crossbow archers, two longbowmen, and two short archers. According to the tactical rule, the crossbowmen attacked first, followed by the longbowmen, and finally the shortbowmen. At the back of the Mandarin Duck Formation, the three hundred longbowmen were divided into three rows, and they all put their bows on the bowstrings, which could be fired at any time.

Just as the chariot of the Yan army rushed to a distance of about a hundred meters from the Wu'an array, sixty crossbowmen pulled the trigger and fired crossbow arrows, while the longbowmen in the first row also shot the arrows in an oblique position.

Flat shooting, projectile, shooting at the Yan army together, rushing in the front row of seven chariots of four chariots of the war horse arrows, screaming to the ground, three chariots overturned, at the same time in the back because of the dodge, crashed up, as a result, the car overturned, dead and wounded.

The longbowmen and short archers also opened their bows and shot arrows, and the arrows fell like raindrops for a while, which immediately caused a heavy blow to the chariots of the Yan army. But it has not yet come close to the array of the Wu'an Army.

Moreover, the more chariots that were overturned, the greater the hindrance to the chariots behind, and it would also cause a lot of trouble to the subsequent attack, so Fan Yuzhi also immediately ordered the chariots to stop attacking and withdraw immediately. At the same time, he ordered people to clean up the overturned chariots on the battlefield.

After the Yan army retreated, the Wu'an army also stopped firing arrows, and when the soldiers of the Yan army came up to clean up the overturned chariots on the battlefield, the soldiers of the Wu'an army did not release arrows, allowing them to calmly move the chariots away and free up the space on the battlefield.

Fan Yuzhi saw it, and he couldn't help but feel a little frightened, although this time he didn't test the power of this strange formation of the Wu'an Army, but looking at the Wu'an Army's appearance, it also made Fan Yu's psychology extremely cautious, because the Wu'an Army dared to let the Yan Army clean up the battlefield, which also showed that they had full confidence in their combat ability.

In a short time, the battlefield was basically empty, and Fan Yuzhi ordered again, this time sending 5,000 infantry to attack the Wu'an army.
