After resting for the night, the next morning, the first thing Gao Yuan did after getting up was to inspect the defensive position arranged by Zhongsun Qi with the generals.

Although the entrance to the valley was not wide, Zhong Sunqi did not set up a defensive position at the mouth of the valley, but pushed the defensive line out of the mouth of the valley at a distance of about a hundred paces and set it as the first line of defense. The whole defense line is arranged in a prismatic shape, with horse-drawn carriages, horses, wooden fences and stones to form fortifications, and at the same time, more than four arrow towers more than one zhang high are also erected.

At about ten paces or so on the outer edge of the fortifications, a trench was dug about one zhang wide and eight feet deep, and more than ten trenches were connected to the camp through guò, which were separated by wooden fences. The soldiers in the camp could defend in the trenches first, and after the Huns captured the trenches, they returned to the camp through the guò trench and lowered the wooden fence to block the entry of the Hun soldiers. More than a dozen bridges were erected with wooden fences on the trenches, which could be used by the army to enter and exit in peacetime.

At the mouth of the valley, a second line of defense was arranged to prevent the men and horses from retreating into the valley after the first line of defense was breached, relying on the second line of defense to resist the Xiongnu army, and the third and fourth lines of defense could also be arranged in the valley to gradually offset the attack of the Xiongnu army. The same is true for the other passages that connect to the valley, expanding the defensive line beyond the valley to allow room for retreat.

At this time, outside the mouth of the valley, and other valley mouths with horse-drawn carriages, horses, wooden fences and stones and other things to build fortifications are basically completed, but the trench is still nearly half of the work unfinished, and the second line of defense has only a general outline, now Zhongsun Qi is concentrating most of his forces to step up the construction of the trenches, after all, the establishment of the second line of defense is not a very urgent matter, can be slowed down a step.

On the whole, although the defense line is a little poorly arranged, but under the existing conditions, it is already very good, but the Xiongnu army is not like the armies of the Chinese countries, there is no equipment for attacking fortifications, only human pads can be used, and there is a lack of armor and protection, so the plateau believes that such a defense line can completely block the attack of the Xiongnu army.

In addition, there is no shortage of wood and stone in the camp, but there is a lack of bronze, iron and other metals, and there are no craftsmen, so it is impossible to make large defensive equipment such as bed crossbows and trebuchets, and even bows and arrows cannot be made.

Gao Yuan is very satisfied with the layout of the defense line, and it is indeed very good to be able to build the defense line like this in just a few days, mainly because Zhongsun Qi is very tightly supervised, and the people of the Bailing clan also know that this is related to their own life and death, so they also work very hard, and there is another factor is that the animal power is sufficient, although the number of the Bailing clan is not large, but there are nearly 8,000 cattle and more than 20,000 horses, which are very large animal power placed there, which also ensures the rapid progress of the project; Now before the arrival of the Hun army, it is estimated that there are still two or three days left, if we hurry up the work, it is still possible to complete all the works before the arrival of the Hun army.

However, the plateau also made some additions to the defense line, one is to insert many barbs and oblique thorns in the trenches, used to block the attack of the Hun army, after all, the trenches only play an auxiliary defensive role, mainly to drag along and slow down the advance of the Hun army, not the main battlefield, the army is not much when fighting in the trenches, so you can set up more lethal weapons, the second is to dig a lot of pits at the front of the trenches, each pit does not need to be very large, more than a foot deep, half a foot to see the circle can be, and then covered with floating soil. The main role is not to trap, but to deal with the war horse, as long as the running war horse steps into such a pit, it will immediately stumble and fall to the ground, and even break the leg bone, which can slow down the cavalry assault of the Hun army.

After seeing the arrangement of the fortifications, it was already noon, Gao Yuan led everyone back to the valley to rest, and Gao Yuan also made arrangements, in addition to sending scouts, closely monitoring the Xiongnu army, reporting the movements of the Xiongnu army at any time, and gathering all the old, weak, women and children of the Bailing clan in the valley, all handed over to Yun Yao to manage, mainly responsible for logistics affairs, and the young and middle-aged people were divided into three groups, taking turns to garrison on the defense line, commanded by Zhongsun Qi, and all the troops were mobile forces, waiting for the opportunity to move. At the same time, more than 2,000 Bailing people were sent to look for wild beasts in the mountains to train and uniform, and prepare for an all-round battle against the Xiongnu army.

In the afternoon, the plateau and the exit of the valley, but also the defensive positions behind the valley to inspect one by one, and at dusk in the afternoon, when the camp began to cook dinner, the scouts found a Hun army of about 500 people about ten miles northwest of the camp, although the brigade of the Dai army rushed over, the Hun army had retreated, but this also means that the Hun army has found the location of the Bailing camp.

Of course, this was not unexpected by the plateau, because when the army retreated from the original camp, it naturally left many traces along the road, and the plateau did not let the army clean up these traces, so it is not surprising that the Hun army was able to find here along these traces. From a certain point of view, the plateau also hopes that the Xiongnu army will be able to find here, if the Xiongnu army really does not come, then these things that the plateau did in the early stage will be in vain.

So Gao Yuan only ordered to increase the patrol density of scouts to closely monitor the movements of the Xiongnu army and prevent the attack of the Xiongnu army, while other things remained the same.

At this moment, I saw a soldier walk into the big tent and said, "Report to the lord, we have caught a few spies in the rear camp." ”

The plateau was slightly stunned, the rear camp was at the rear end of the valley, although the fortifications were also established, but after all, it was not as strong and perfect as the position in the valley, if the Hun army found a way to the rear end of the valley, it would naturally be a heavy threat to themselves, forcing themselves to fall into the predicament of being attacked on both sides.

However, there is still some disbelief on the plateau, because this area is not the main area of activity of the Huns, how could the Huns find the road to the back of the valley so quickly, and it is difficult to find a guide? At this time, Gao Yuan couldn't help but think of Zhong Sun Qi again, he said that he had found a village in the valley, could it be the people of this village? And will this village have a connection with the Xiongnu?

Thinking of this, Gao Yuan said: "Have you asked them, who are they?" ”

The soldier who reported the incident hesitated for a moment before saying, "They seem to be from the Huaxia clan." ”

When Gao Yuan heard this, he couldn't help but be surprised, would there be a Chinese people here? Turning his head to Shui Xinyue, he said, "Besides Fu Gongyan, is there anyone else in the Xiongnu tribe?" ”

Shui Xinyue also remembered that Zhao Xin and Ma Yu under his command had completely taken refuge in Fu Gongyan, but after thinking about it, he said: "Of course he will bring a few of his subordinates to deal with some chores for him, but he shouldn't let them do such a thing as exploring the road." ”

Gao Yuan also nodded, this is reasonable, although Fu Gongyan's martial arts, knowledge, and strategy are all clever, but after all, he is not a grassland nomad, and he must not be able to do the thing of pathfinding, so he immediately said: "Okay, bring them to see me?" ”

After a while, the soldiers came to the big tent with a few people tied up with flowers, and sure enough, they were all Chinese people's clothes and appearances, Gao Yuan was about to ask, and suddenly heard someone say: "Wu Anjun, are you Wu Anjun?" ”

Gao Yuan couldn't help but be stunned, is there anyone here who knows himself? Looking carefully at the person who spoke, I saw that he was about fifty years old, with a cloth towel covering his head, and he was dressed in linen clothes, and his face was somewhat familiar, but he couldn't remember where he had seen this person for a while.

Seeing that Gao Yuan sensed his question, the man immediately said: "In Xia Zhai Jin, I have known Wu Anjun in Zhao Country several times, do you remember Wu Anjun?" ”

Gao Yuan then remembered, this person is really Zhai Jin, he is a scholar of the Mo family, but also the figure of the Mo family of Zhao Guo, when he was still in Zhao State, he did have a few friends with him, and then came from the county that has entered the main county, attacked Yin Mountain, and met Zhai Jin on the way, when he took a group of disciples of the Mo family, was hunted down, it was Gao Yuan who rescued Zhai Jin, and it was Han Teng's subordinates who chased and killed Zhai Jin at that time.

Later, Zhai Jin took the disciples of the Mo family of Zhao to settle down in Daijun, and spread the doctrine of the Mo family, and took advantage of the large number and wide range of Mo disciples to help the plateau establish intelligence agencies in various countries, which played a certain role.

However, the plateau is an equal attitude towards the hundreds of schools of thought, as long as it does not affect their own rule in the county, they basically do not interfere, but in terms of governance, the plateau is based on the Legalists, and the principles of Confucianism and Taoism, but there is nothing to do with the Mohists, after all, the plateau is clear, the law, Confucianism, and Taoism have their own strengths in governing the country, and they are used in different eras of Chinese history, although after the Tang and Song dynasties, Confucianism rose to the orthodoxy of the country, and became the basic policy of governing the country. However, in fact, it has absorbed many of the concepts of the two schools of law and Taoism, and in fact, it is a combination of the three schools of law, Confucianism, and Taoism, but it is carried out under the packaging of Confucianism.

However, in Chinese history, there was no dynasty that would use Mohist ideas to govern the country, so although the Mohists helped Gao Yuan do some things, they were still not valued by Gao Yuan, and Zhai Jin was rarely summoned, so Zhai Jin could only spread Mohist doctrine among the people, but the progress was not great. So Zhai Jin stayed in Dai County for a few years, so that the Mo family gradually stabilized in Dai County, so he took some younger brothers and went to Saiwai to find the Mo family's younger brothers who went to Saiwai to live in seclusion.
