"Chirp-chirp-chirp-"

With a pair of flying birds flying in the sky overhead, they circled and landed on the two hands stretched out by Yun Yao. The two birds were about a foot long, one grayish-brown and the other reddish-brown, and covered with dark brown spots or horizontal stripes, with a shorter beak with a distinctly downward curve into a hook, long, narrowly pointed wings, and a slender tail. It turned out to be a pair of kestrels.

One of the biggest problems in ancient warfare was that the means of communication and reconnaissance were very backward, and the failure of many battles was often related to the lack of communication or reconnaissance methods. Gao Yuan also had a headache about this problem, and he carefully trained the special combat team in the hope that they would play a role in reconnaissance. In the past, Gao Yuan only paid attention to Yun Yao's healing ability, but this time he was outstanding, and he thought that Yun Yao also had the talent to train beasts, if he made full use of it, he could completely improve his reconnaissance ability to a higher level, and he could also make a breakthrough in communication in the future.

At this time, Gao Yuan also received the news sent back by Jiang Huanwu, and at this time, the Yan army was still stationed outside Juyong Sai and did not open up, so Gao Yuan led three thousand cavalry, left the valley, and rushed to join Jiang Huanwu and others, of course, he also brought Yun Yao.

After leaving the valley, Yun Yao used his talent for animal training to capture a pair of under-adult kestrels on the road and began to train their reconnaissance abilities.

Generally speaking, the falcon is a small and medium-sized bird of prey, known for its strong flying ability and good eyesight, and some larger falcons can also be called eagles, and the kestrel is a classic category of the falcon in northern China, also known as the tea falcon, red eagle, yellow eagle, red harrier, strong flying power, like to fly against the wind, and can quickly flap its wings and stop in the air, and the eyesight is agile, feeding quickly, when there is food on the ground, it can quickly dive to capture, and sometimes it can also directly catch small birds and insects in the air. It is a very good bird for scouting.

Gao Yuan is naturally very happy, even if he can't catch up this time, but if he trains this pair of kestrels, it will still be of great use to his future battles.

After walking all the way for two more days, the army arrived at a place about fifty miles outside Juyongsai and joined Jiang Huanwu and others.

Jiang Huanwu also reported to the plateau that the original strength of the Yan army on this road was 120,000, and the reason why the troops were not moved was because the Yan army was now full of internal contradictions, fighting with each other, and dragging on the time of the march.

Although nominally, the commander of the Yan army was Yan Prince Dan, Tai Xiao Dan was not proficient in the art of war, so he mainly obeyed the Qin general Fan Yuzhi's Jian. When Fan Yuzhi was in the Qin State, he was also a famous general, and Wang Jian, Huan Qi, and Mengwu were on a par, and his ability to use troops was indeed trustworthy, much stronger than the Yan generals who had been defeated repeatedly, and there was no contradiction between Qin and Yan, and it was completely reasonable for Prince Dan to rely on Fan Yuzhi.

Moreover, although Fan Yuzhi was in the Yan State, he also inquired very clearly about the history of the first battle of Jingcheng, and the destruction of the Zhao State, the independence of the plateau in Dai County, and the establishment of the Wu'an Army. In Fan Yuzhi's view, the plateau has already won the true transmission of Li Mu's art of war, and is good at using cavalry to carry out large-scale attacks. The place north of the water control is surrounded by many mountains, which is just conducive to the Wu'an army to set up ambushes and assaults, so the Yan army should not rush forward, but should advance step by step. At the same time, Fan Yuzhi also sent an elite cavalry to Tai Yu Dan to make a detour north of the Great Wall to raid Shanggu County, and the two marches echoed each other, which could make the Wu'an army difficult to take care of, and then cooperate with the Yan army on the south bank of the water, which did have a great chance of winning, after all, the Yan State had an absolute advantage in military strength.

However, Fan Yu's construction was also strongly opposed by the Yan general Li Li, who was the son of the Yan Xiangguo who died in the Yan army attacking Zhao twenty-five years ago. However, he was very dissatisfied with Tai Yudan's attitude of relying on Fan Yuzhi, thinking that Fan Yuqi was just a fugitive general of the Qin State, and it was already very good for the Yan State to be able to take him in, so it was worth relying on him so much. And now Li Li is the general of Yan State, in charge of the military power of Yan State, so he naturally does not want anyone to threaten his position. Therefore, as long as Fan Yuzhi proposed it, he would strongly oppose it.

In addition, Li Li also despised the strength of Daijun very much, thinking that it was just a group of remnants of Zhao State, and what strength could it have if it survived in Daijun, and now the Yan army was 200,000 troops, and it was just a walk, and Daijun could be leveled, and it was as complicated as Fan Yuqi said. Just by commanding the army, advancing along the water control and advancing all the way to Uetani County, you can defeat the army of Daijun in one fell swoop. Moreover, there are many places that are difficult to realize.

Because the Yan army is not the Qin army, the Yan country is a very conservative country, until now, the Yan army is still based on chariots as the main force, did not establish an independent cavalry army, only a few scattered cavalry, and after Fan Yu entered Yan, he has been placed outside the Great Wall by Tai Xiaodan, and he does not know the situation of Yan State, and equates Yan State with other countries, in fact, it is impossible for Yan State to send an elite cavalry army to raid Shanggu County from the north of the Great Wall.

And the Li family is a big family in the Yan country, and the power in the Yan country is deep-rooted, and even the royal family of the Yan country does not dare to offend the Li family lightly, so Li Li insists on not agreeing to the implementation of Fan Yuzhi's construction, and Tai Xiaodan has no way to take him.

As a result, the two sides argued for several days over how to send troops, but no result was reached. And seeing that the Yan army on the southern front had been driven for three days, walked out of nearly 100 miles, and had a skirmish with the Wu'an army, it could not be delayed any longer, so Tai Xiaodan also had to compromise with Li Li and gave up Fan Yuzhi's Jianyi. In the face of the pressure of Tai Yu Dan, Fan Yu Zhi could only change his plan, and also gave up the plan of making a detour from the north of the Great Wall to raid Shanggu County, and divided the whole army into three parts, with Li Li leading 50,000 horses as the vanguard, Tai Yu Dan and Fan Yu Qi led 50,000 troops in the center, and the remaining 20,000 troops escorted grain and grass materials, at the rear.

This plan also made Li Li very satisfied, although he was only assigned 50,000 troops, but he was the general of Yan State, in charge of the military power of Yan State, so these 50,000 troops are all elite soldiers of Yan State, with the strongest combat effectiveness, and can withstand more than 100,000 troops. Li Li is also full of confidence, with only these 50,000 troops, it is enough to defeat Daijun's army and capture Shanggu County. So after dividing the troops, Li Li immediately led the army and marched along the control of the water to Shanggu County.

Of course, Jiang Huanwu and the others did not know about the power struggle within the Yan army, but the Yan army was divided into three sections and attacked Shanggu County, and they still explored very clearly, and at this time, the front of Li Li had already opened a distance of about thirty miles from the Chinese army of Prince Dan. According to the standards of the art of war in the Spring and Autumn Period, thirty miles is almost the distance of a day's march. Although the armies of all countries at this time expanded the distance of a day's march to about fifty miles, the Yan State still respected this tradition.

After Gao Yuan learned the whereabouts of the Yan army, he also immediately made a decision, since the Yan army was divided, then he could just break the Yan army one by one, but the first thing to do was to let the front army of the Yan army and the middle army distance themselves, let the front army break through, give themselves the opportunity to concentrate their forces, and annihilate the front army of the Yan army first, and at the same time delay the advance speed of the Yan army, so that they could not quickly support the front army.

Therefore, Gao Yuan immediately ordered Zhong Sun Qi to lead the 3,000 cavalry he brought, pay the Chinese army that attacked the Yan army, and immediately return to the valley to prepare to concentrate his forces and encircle and annihilate the front army of the Yan army.

This time, the three thousand cavalry brought by the plateau, including a thousand cavalry of a Xiao cavalry army, plus two thousand cavalry of the collection, after Zhongsun Qi received the order, he immediately led the army to set off, bypassing Li Li's front army, and went straight to the middle army of the Yan army. Because at this time, Jiang Huanwu and the others had already figured out the roads in this area, so the front army of the Yan army did not realize that they had passed by the enemy army at all.

After passing the front army of the Yan army, Zhong Sun Qi led the Wu'an army and launched a surprise attack on the Chinese army of the Yan army at night. Yan Jun really did not expect that the Wu'an army would bypass the front army and attack itself, and was unprepared for the attack of the Wu'an army, and the garrison was very lax, and as a result, the Wu'an army broke through two camps in a row. By the time the Yan army's army came to the rescue, the Wu'an army had already fled without a trace.

Although the losses caused by this raid to the Yan army were not large, with only three or four hundred soldiers killed, and less than a thousand wounded soldiers, it still brought a lot of shock to Prince Dan and Fan Yuzhi. Therefore, Fan Yuzhi did not dare to be careless, and when he marched during the day, he also sent a large number of patrols to patrol around the army to protect the army from further attacks.

As a result, during this day's march, the Yan army was attacked several times by the Wu'an army, although Fan Yuzhi's arrangement did protect the safety of the brigade, but the Wu'an army was difficult to attack the Yan army's army, but specifically aimed at the Yan army's patrols.

Because the Yan army did not have a special cavalry, the patrol team was a mixed group of chariots and horses, and it was mainly based on light vehicles, usually two or three chariots with more than ten cavalry, forming a patrol team. Such a device is simply vulnerable in front of the elite cavalry of the Wu'an Army, and often a 50 cavalry or 100 cavalry can easily defeat a patrol squad by attacking two or three times. By the time the reinforcements of the Yan army arrived, they had already run away.

As a result, at the end of the day, more than ten patrols of the Yan army were attacked by the Wu'an army, and six of them were wiped out, and more than 100 soldiers were killed in battle. None of the soldiers of the Wu'an Army were killed, and only a dozen soldiers were injured.
