A foot high was raised on the ground, and beams and wooden piers were laid out. Then layers of wooden boards were laid on it. The inside was basically hollow, but a lot of well-cut wooden sticks, neither thick nor thin, were added as supports. . With the addition of a large number of wooden nails, a frame gradually appeared in the foundation of a camp. All that was left was to fill the space between the empty wooden boards and the ground with insulation material. For this purpose, all the generals who had practiced Qi to become Gang were basically ordered to come over for wood shaving. Almost seven to eight thousand fine pine and fir trees were forcibly chipped, soaked in oil and then filled into the gaps between the boards and the ground. . After warming, oil-soaked pine shavings, and a large amount of sawn wood were added, the thermal insulation was terrible. After the efforts of more than 10,000 Yuan troops, eight days later, the Han army finally completed the construction of its own camp, covering 2,500 The terrifying scope of the remaining acres. By the way, this camp is more than a foot higher than the Northern Huns, but the snow is so heavy now that there is no obvious difference at all. The heavy snow has successfully completely covered up what Shen Pei and others wanted to cover up. Of course, during the eight days when the Han army was building their camp, the Northern Huns did feel that their days were like a year. Finally, on the sixth day, they could no longer bear it and sent more than 3,000 tribesmen to attack the Han army in the wind and snow. . Unfortunately, starting from the fourth day, Xun Chen had already ordered people to loosen up the outside and tighten up inside. He strengthened the alert, canceled all night patrols, and instead deployed a large number of hidden sentries in specially built wooden camps. After moving the movable wooden boards one by one, the hidden sentries only needed to Just climb in and that¡¯s it. A large number of pine and fir shavings are as warm as winter clothes. The whistle only needs to lie inside. The hollow wooden structure allows the sound of footsteps to be transmitted more clearly, so most whistles only need to lie there to accurately know the surrounding area. Is there an attack? Some secret sentries even prepared quilts in advance, and they would sit in groups of three and lie in the wood shavings covered with quilts to rest, which was no worse than in a tent. The originally sad situation of patrolling in the winter was forced by Xun Chen to lie in bed and monitor. Apart from forcing the three of them not to rest, Xun Chen did not pursue much in other aspects. Naturally, in this case, no group of Han soldiers' secret sentries would be able to cheat. Also in this case, the Northern Huns' sneak attack had no chance of success. After all, it would not be possible to kill the Northern Huns. They will think that the soldiers of the Han army are at their feet. Under this circumstance, the night attack on the sixth day when the Han army camp started to be built was a tragedy for the Northern Huns. Even the secret sentry itself did not know that Xun Chen scattered more than 3,000 people among the wood shavings under the camp floor as secret sentry. With such a terrifying scale, even without a single patrolling soldier, it was absolutely impossible for the Northern Huns to hide their presence. . Of course, the Northern Huns who attacked by surprise thought that the Han army was too negligent and gave them a considerable opportunity. As a result, the Northern Huns entered the camp and went deep into the camp for a long time. They confirmed that the Han army really had no soldiers patrolling at night. They were overjoyed and prepared to forcefully attack the Han army at night. At the core, we were attacked by the Han army from both front and rear! Except for the more than a thousand Shenpei who stayed behind, all the more than three thousand Northern Huns were killed. The sudden front and rear attacks by the Han army caused the Northern Huns to suffer a heavy blow without even reacting. Then, under the leadership of a certain Northern Huns general, the Northern Huns rushed left and right, and successfully approached the grain and grass storage area at the core of the Han army. By setting fire to attract the attention of the Han army, they successfully broke through the encirclement and escaped. Of course, these are all nonsense. Shen Pei just wants to let the Northern Huns out. After all, if they want to win a big victory, they must think of some strategic things when their troops are insufficient, and now is a good opportunity. After killing 2,000 Northern Huns with relatively small losses, Shen Pei and Xun Chen no longer focused on the Northern Huns. On the eighth day after the camp was completely built, Xun Chen and others finally entered the verification stage before implementing the strategy, and several people began to make detailed comparisons. "The food here is not very safe. Do you have any good ways to deal with it?" What should we do? Food is the foundation of survival. "No matter how we deal with this thing, we can dig out such troublesome things. Find a place to dig a hole for this thing, lay wooden boards below, cover it with wooden boards, and then bury them all." Xu You curled his lips and said, "This Leave it to me. By the way, you have a lot of wood shavings that you can¡¯t deal with. Leave it to me. " "First of all, have you dug it through?" Xun Chen looked at Xu Youbai and asked. A piece of dark green jade, my IQ has increased a lot. By the way, Xu You, who is cheap recently, always wants to dig that open-pit jade mine. "It worked. The soldiers worked harder than I thought. Probably there must be brave men under the heavy reward. The tunnel has been dug. Because of the heavy snow, the sound of tunnel digging was basically absorbed by the snow." Xu You nodded and said. Xu You estimated that he had already dug somewhere, so he had someone take a peek late at night, and then sealed the place with loess. "But what surprises me now is that the Northern Huns actually implement unified management. Women cook together. There are many guards in the middle camp. It seems that they also know what is most important." Xu You said with a solemn expression. "What are your plans?" Xun Chen looked at Xu You and asked. "I need some wood for support. I plan to hollow out the place. It is expected to take three days. If it is done day and night, it will take two days. If it is only done when it is safe, it will take three days." Xu You said. "Well, on that day, Ziyuan, you and I forcefully stop the heavy snow, and leave the rest to Zhengnan, living on the torch. I'm really worried that one of us will be careless one day." Xun Chen said slightly. He said helplessly that their current camp was really dangerous. "Three days, wait three more days and we will see the outcome." Xu You said solemnly, looking at the two of them. "Okay, I'll rely on you in this aspect." Shen Pei also looked at Xu You with great solemnity, and then Xun Chen also stretched out his hand, "We are confident of victory. Total annihilation is not that easy. Ziyuan, you have been here for the past three days. Do your thing, Zhengnan and I will think about how to annihilate the Northern Huns." Shenpei nodded and agreed with this. What Xu You has to do is really related to the next victory or defeat. After the three people discussed it, they went to report to Yuan Tan, and then Xu You continued to study how to take away the Northern Huns' granary. You must know that the Northern Huns' current grain is mainly divided into cattle buried in the snow. Sheep carcasses, and a large amount of grain in the granary. Getting rid of the grain in the granary is not a problem for Xu You, but the extremely large number of cattle and sheep buried in the snow is Xu You's biggest problem. Although the Northern Huns are destined to run out of food soon if they burn the grain, the millions of fat sheep buried in the snow are enough to feed the Northern Huns for more than a month, and for Shenpei and the others, they are not that good at all. A lot of time is spent here. ¡¾It¡¯s a gamble, there is no way to move or burn the cattle and sheep buried in the snow in a short time, so we can only rely on guidance. ¡¿Xu You pressed his temples and thought silently. ¡¾Do you speak Xiongnu language? There must be someone in the camp, but even so, it will not be enough to annihilate the Northern Huns. Once the Northern Huns scatter and run away] Xu You looked a little ugly, although he also knew that annihilating them all would be very difficult. In fact, As long as the achievement of annihilating nine is achieved, the Northern Huns will basically be destroyed. "Uh, what are you doing?" When Xu You was walking in the camp, he found a captain who was not patrolling properly and was actually playing in the sand! "I've met Military Master Xu!" Chen Jie reacted quickly. After noticing Xu You, he immediately stood up and saluted Xu You. "Let me think about it, by the way, your name is Chen Shurong. You were recommended to the lord by Gongze a few years ago. I remember you were already a captain before, so why are you now a captain of thousands?" Xu You stared at Chen Jie for a while. , finally remembered why he looked familiar. This guy was recommended to Yuan Shao by Guo Tu and had appeared in front of him several times. "General Master Xu actually still remembers me." Chen Jie said with a hint of surprise. "What are you doing?" Xu You didn't want to pursue Chen Jie's question at this time and asked. Chen Jie was slightly embarrassed and took out a spoonful of sand from the wooden bucket on the side. When he turned around to scoop water into another bucket, the water in the bucket had frozen. He reached out to break the ice and poured a spoonful of water over it. On the sand, with the cold wind blowing, Chen Jie vigorously broke off the frozen sand. Then he scratched his head and said to Xu You, "Commander Xu, I was born in Yingchuan. I have never seen anything like this before, so I am getting playful. Please forgive me, military counselor." Xu You looked Chen up and down. The piece of sand in Jie's hand was basically frozen, and his eyes couldn't help but shine. He suddenly realized that the issue of the Northern Huns' escape was not unsolvable. "Shurong, do you know the Huns?" Xu You asked casually. "Yes." Chen Jie was stunned for a moment and replied, "Actually, I can not only speak Xiongnu dialect, but also Xianbei dialect, Nanyue dialect, Jie dialect, and seven or eight local dialects." Xu You was stunned at this moment. "Why do you learn so many languages?" "It's not what I want to learn." 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. Within a few months, I could speak their language as well as they did.Familiar, I know so many languages ??because I have stayed in those places. Xu You looked surprised and said, "Sure enough, fate is with us as a big man. Say a few words of Xiongnu to me and make it fluent. For example, let someone follow you to charge or something." " Chen Jie didn't think much, so he repeated it in Xiongnu dialect. His words were so fluent that Xu You even doubted whether Chen Jie was a Huns in Han skin. "That's very good, very good, hahahaha! "Xu You looked up to the sky and laughed, "Now I will give you a task, take my warrant to find the lord, the lord will arrange the task for you, and you will be sung by Qingshi like your two clan brothers. " Chen Jie didn't understand why Xu You was so excited, but after receiving Xu You's order, he began to execute it to the letter. Yuan Tan looked at Xu You's handwriting and looked Chen Jie up and down. "You will be a lieutenant colonel in the army from now on. Now lead your three thousand people, as well as Zhu Han, Jiang Qi, and Wang Mo's troops to build a city wall around the camp outside the camp using the same method you used to play with sand. " "No! "Chen Jie said excitedly. "It was night, and 12,000 Han troops built a wall thirty meters outside the camp. The wall was not high, only more than two meters, but it was two feet thick. It was all dug on the spot by the Han troops that night. The soil layer was then watered, but this level was far from enough for Xu You's requirements. Of course, the Han army who built the outer wall by himself was not surprised by the enemy, but they suddenly discovered it the next day. The Northern Huns were shocked when there was a wall outside the Han army's camp. But it didn't matter. They continued to build it the next day, using local materials. The efforts of 21,000 people made the wall five feet thick. The seven-foot-thick city wall reinforced with ice has already caught up with or even surpassed the thickness of most city walls in this unscientific Central Plains. However, the city walls in the Central Plains have been warmed and maintained by the residents of the city, and are stronger than normal! Twice as strong, so reinforcements are still needed. On the third day, which is the last day, the Han army no longer cares about hiding or not. All the Han army took action day and night. For this reason, the original plan was even postponed for one day. The entire perimeter The wall was forcibly thickened to ten feet, and the height was also increased to ten feet. Even without the warmth of the clouds, the integrated effect achieved by the frozen sand is enough to withstand the legion's attack. Destroyed. To put it simply, even the large-caliber artillery of later generations has no good way to deal with a building of this size. Only four entrances and exits about ten feet wide from east to west, north and south are left, and the rest are surrounded. When they got up, the Northern Xiongnu were so excited that they even started to imitate the Han army in construction on the fourth day. However, due to the continuous harassment of the Han army, only a wall of about three kilometers has been built so far. The Xiongnu's manpower is several times that of the Han army, and it takes less than a few days to completely establish a defense line, but the Northern Xiongnu has been gone for a few days. "The judge looked at Chen Jie, who was no different from the Northern Huns, thought for a moment and said, and soon a piece of sheepskin with a strong smell was wrapped around Chen Jie. Chen Jie looked disgusted, but he quickly adapted. Then he made a normal Huns expression, expressed satisfaction, then looked at Xun Chen and others and nodded, "Let's go. "The examiner bowed deeply to Ji Ling, Gao Lan, Jiang Qi, Wang Mo and others, "The victory or defeat depends on us, we must not back down! " "I will obey the general's orders! "Ji Ling and others said solemnly. Afterwards, Shenpei led the generals to the tunnels that Xu You had dug before. After this period of sleepless work, they worked hard in shifts. These more than a dozen tunnels have successfully reached their goals, and each of them has reached its goal. The tunnels were dug to be as wide as three people, and a lot of effort was expended.
