The ground is covered with beams and wooden piers, and then layers of wooden boards are laid out, which is basically hollow, but a lot of peeled wooden sticks are added as support.

With a large number of wooden nails, the frame soon appeared in the foundation of a camp, and the rest was to fill the empty wooden boards below with insulation materials.

For this purpose, all the generals who practice Qi and become Gang were basically shaved with signs. Almost seven or eight thousand of the best pine and fir trees were forcibly shaved, and after soaking oil, they were filled into the gap between the wooden board and the ground.

After warming and oil-soaked pine shavings, coupled with a large amount of sawn wood added, the insulation is terrible. After more than 10,000 Yuan Jun's efforts, eight days later, the Han army finally completed the construction of its own camp, covering a terrifying range of more than 2,500 acres.

By the way, this camp was more than one foot higher than the Northern Huns, but now the snow is too heavy, and there is no obvious difference at all. The heavy snow has successfully covered up what Shen Pei and others want to cover up.

Of course, during the eight days when the Han army built the camp, the Northern Huns did feel like they were living like a year. Finally, on the sixth day, they could not help but send more than 3,000 tribesmen to attack the Han army while the wind and snow.

Unfortunately, from the fourth day, Xun Chen had ordered people to loosen the outside and tighten the inside, strengthened their vigilance, canceled all night patrols, and instead arranged a large number of secret patrols. The wooden camp specially built was built. After moving pieces of movable wooden boards, the secret patrol only needed to climb in.

The warmth of a large number of pine and fir shavings is not inferior to that of winter clothes. The hidden whistle only needs to lie inside. The hollow wooden structure makes the spread of footsteps more clearly, so most hidden whistles only need to lie there to accurately know whether someone is coming on the periphery.

Some even prepared quilts in advance, and in groups of three, lying in the woodshavings covered with quilts to rest, which was no worse than in the camp.

The tragic situation of patrolling in the middle of winter was beaten by Xun Chen and lying in bed to monitor. Except for forcing the three of them to not rest, Xun Chen did not pursue much in other aspects.

Of course, under this situation, there would be no group of secret whistles of the Han soldiers. In this case, the Northern Huns' sneak attacks were not possible at all. After all, even if they killed the Northern Huns, they would not have thought that the Han soldiers were at their feet.

Under such circumstances, the night attack on the sixth day after the construction of the Han army camp was a tragedy for the Northern Huns.

Even the secret whistle itself did not know that Xun Chen sprinkled more than 3,000 people into the shavings under the camp floor as a secret whistle. At this terrible scale, even without a single patrol soldier, the Northern Huns would definitely not be able to hide their figure.

Of course, the Northern Xiongnu who attacked the sneak attack thought that the Han army was too negligent and gave them a considerable opportunity. As a result, when the Northern Xiongnu entered the camp, they went deeper for a long time, and confirmed that the Han army really did not have soldiers patrolling at night. They were overjoyed and prepared to forcibly attack the core of the Han army at night, they encountered a joint attack from the Han army!

The more than 3,000 Northern Huns were killed except for more than 1,000 Shen Pei who stayed there. The sudden attacks of the Han army caused the Northern Huns to suffer a heavy blow without reacting.

Then, under the leadership of a brave general of the Northern Huns, the Northern Huns rushed left and right, successfully approaching the storage of food and grass in the core of the Han army. By setting fire to attract the attention of the Han army, they successfully broke through the siege and escaped.

Of course, these are nonsense. Shen Pei just wanted to let the Northern Huns go out. After all, if they want to win a great victory, they must think about some strategic things when they are short of military strength, and now is a good opportunity.

After killing two thousand Northern Huns with a considerable slight loss, Shen Pei and Xun Chen no longer focused on the Northern Huns.

On the eighth day after the camp was fully constructed, Xun Chen and others finally entered the verification stage before the implementation of the strategy, and several people began to compare in detail.

"The food is not very safe. Do you have any good solutions?" Xun Chen looked at Shen Pei and asked. Although what was burned before was not real food, Xun Chen was still a little worried. What if he missed it later? Food is the foundation of survival.

"How can we deal with this thing? We can dig out such troublesome things. Find a place to dig a hole in this thing, lay wooden boards below and cover them on top, and then buried them all." Xu You curled his lips and said, "I'm leaving this matter to me. By the way, you have made a lot of shavings and can't deal with it, you can't leave it to me."

"Let me first, have you dug it?" Xun Chen looked at Xu You and asked. Recently, Xu You picked up a large piece of dark green jade, and his IQ has increased a lot. By the way, Xu You, who is cheap recently, always wants to dig the open-air jade mine.

"It's clear, the soldiers work harder than I thought. Perhaps there must be a brave man under heavy rewards. The tunnel has been dug through. Because of heavy snow, the sound of the tunnel digging has basically been absorbed by the snow." Xu You nodded and said.

Xu You had guessed that he had dug up the place, so he asked someone to take a peek late at night, and then sealed the place with loess.

"But what I am more surprised now is that the Northern Huns actually implemented unified management, and women cook together. There are many guards in the central camp, and it seems that they know what is the most important." Xu You said with a serious expression.

"What are you planning?" Xun Chen looked at Xu You and asked.

"I need some wood for support. I'm going to hollow out the place. It's expected to take three days, and it will take two days if it's day and night. If it's only done at a safe time, it will take three days." Xu You said.

"Okay, by that day, Ziyuan and I will forcefully stop the heavy snow, and leave the rest to Zhengnan, and live on the torch. I am really worried that one day someone among us will be careless." Xun Chen said helplessly. Their current camp is really dangerous.

"Three days, wait three days and you will see the winner." Xu You looked at the two of you and said solemnly.

"Okay, it depends on you in this regard." Shen Pei also looked at Xu You solemnly, and then Xun Chen also extended his hand, "We are confident in victory, and it is not that easy to wipe out the entire Xiongnu. Ziyuan has done your work in the past three days, and Zhengnan and I will think about how to wipe out the Northern Xiongnu."

Shen Pei nodded and agreed with this. What Xu You wanted to do was really related to the next victory or defeat.

After the three of them discussed, they went to report to Yuan Tan together, and then Xu You continued to study how to remove the Northern Huns' granary. You should know that the current grain and grass of the Northern Huns are mainly divided into cattle and sheep corpses buried in the snow, as well as a large amount of grain in the granary.

For Xu You, the grain in the granary was not a problem, and the huge number of cattle and sheep buried in the snow was Xu You's biggest problem.

Although the Northern Huns were destined to be out of food soon after burning out the food, more than one million fat sheep buried in the snow were enough for the Northern Huns to eat for more than a month, and for Shen Pei and others, they did not have so much time to spend here.

[I’ve had a gamble. The cattle and sheep buried in the snow have no way to move them away or burn them in a short time, so I can only rely on guidance.] Xu You thought silently while pressing his temple.

[Does the Huns say it? There must be someone in the camp, but even so, it is not enough to completely wipe out the Northern Huns. If the Northern Huns scatter and run away...]

Xu You's face looked a little ugly. Although he knew that it was very difficult to completely annihilate. In fact, as long as 90% of the total annihilation were achieved, the Northern Huns would have basically destroyed.

"Uh, what are you doing?" Xu You was walking in the camp and found that a commander was not patrolling properly and was actually playing with sand and soil!

"I have met Military Advisor Xu!" Chen Jie's reaction was quick. After realizing Xu You, he immediately stood up and politely said to Xu You.

"I think about it, by the way, your name is Chen Shurong. A few years ago, you were recommended to your lord by your husband. Before, I remember that you were both a lieutenant, why have you become a commander again?" Xu You stared at Chen Jie for a while, and finally remembered why he looked familiar. This guy was recommended to Yuan Shao by Guo Tu, and he appeared in front of him several times.

"Mr. Xu still remembers it." Chen Jie said with a little surprise.

"What are you doing?" Xu You didn't want to pursue Chen Jie's problem at this time and asked.

Chen Jie made a spoonful of sand and soil from the wooden barrel beside him with a little embarrassment. When he turned around and was about to scoop water in another barrel, the water in the barrel had frozen. He reached out to smash the ice surface and scooped a spoonful of water on the sand and soil. When the cold wind blew, Chen Jie vigorously broke off the frozen sand and soil.

Then he scratched his head and said to Xu You, "Military Xu, I am from Yingchuan, and I have never seen this situation there before, so I have a lot of fun. Please forgive me for your military advisor."

Xu You looked up and down at the piece of sand that was basically frozen on Chen Jie's hand, and his eyes lit up. He suddenly realized that the Northern Huns were going to run away, which was not impossible to solve.

"Shurong, do you know how to talk to the Huns?" Xu You asked casually.

"Yes." Chen Jie was stunned for a moment and replied, "Actually, I can not only know the Xiongnu dialect, but also the Xianbei, Nanyue, Jie dialect, and seven or eight local dialects."

Xu You was stunned, "What are you doing when you learn so many languages?"

"It's not what I want to learn by myself." Chen Jie scratched his head, "It's just that I can barely communicate with the locals after staying in one place for more than half a month. After staying in three months, I can speak their language as well as them. I can talk so many things because I have been in those places."

Xu You looked surprised, "Sure enough, Tianyun is in our great man. Let me listen to the Huns, and be fluent, for example, if someone follows you or something."

Chen Jie didn't think much about it, but repeated it in the Xiongnu words. His fluent speech made Xu You wonder if Chen Jie was a Hun in the skin of a Han people.

"It's very good, very good, hahaha!" Xu You laughed to the sky, "Now I'll give you a task, take my warrant to find the lord. The lord will arrange a task for you, and you will sing it in history like your two brothers."

Chen Jie had no idea why Xu You was so excited, but after taking Xu You's warrant, he began to execute it without fail.

Yuan Tan looked at Xu You's handbook and looked up and down at Chen Jie, "From now you will be a captain in the army. Now you will lead your 3,000 people, as well as Zhu Han, Jiang Qi and Wang Mo's men to go outside the camp to build a city wall around the camp by using the way you used to play with sand."

"No!" Chen Jie said excitedly.

That night, 12,000 Han troops built a wall thirty meters away from the camp. The wall was not high, only more than two meters, but it was as thick as two meters. It was all made by the Han army dug soil on the spot and then watering it. However, this level was far from enough for Xu You's requirements.

Of course, the Han army, who built the outer wall with his own hands, did not have any surprises at the enemy. However, the next day, he suddenly found that there was an extra wall outside the Han army camp, and the Northern Xiongnu were shocked.

But this is not important. The construction continued the next day, and the materials were used locally. The efforts of 21,000 people made the city wall five feet thick, and the thick ones were reinforced with ice to form an integrated city wall. It has caught up with and even surpassed the thickness of most of the unscientific city walls in the Central Plains!

However, the city walls of the Central Plains have been warmed by the residents of the city, and the degree of solidity is twice as strong as normal, so they still need to be strengthened.

On the third day, that is, the last day, the Han army no longer cares whether to hide it or not. All the Han army takes action regardless of day or night. For this reason, it even delays the original plan for a day. The entire outer wall was thickened to ten feet and the height was also raised to one foot.

Even if the wall of this level is not nourished by clouds, the integrated effect achieved by frozen sand is enough to withstand the damage of the legion's attack.

Simply put, even the large-caliber artillery of later generations has no good way to deal with buildings of this level.

Only four imports and exports, about ten feet wide, were retained, from east, west, south, north and north, and all other places were surrounded. The Northern Huns were particularly excited to see them.

Even on the fourth day, they began to imitate the Han army for construction. However, due to the continuous harassment of the Han army, only a wall of about three thousand meters has been built so far. The manpower of the Northern Huns is several times that of the Han army. It took only a few days to build a line of defense, but the Northern Huns have not had that few days.

"It almost smells like a sheep." Shen Pei looked at Chen Jie, who was no different from the Northern Huns, and said after thinking for a while. Soon a strong smell of sheepskin was wrapped around Chen Jie.

Chen Jie looked disgusted, but he quickly adapted, and then he looked like a normal Hun. Shen Pei expressed his satisfaction, and then nodded at Xun Chen and others.

"Set out." Shen Pang bowed deeply to Ji Ling, Gao Lan, Jiang Qi, Wang Mo and others, "The victory or defeat is up to us, we must not retreat!"

"Abide by the general's order!" Ji Ling and others said solemnly.
Chapter completed!
