On a snowy night, the cold wind still raged on the earth, and the trees and tents around the camp were whining.

Mulan took her own soldier and herald and three soldiers to inspect the sentry posts, patrols, and the sleeping conditions of the soldiers in the camp tent.

The soldiers carried lanterns in front, and the lanterns illuminated the road ahead, and they came to the hill, where the wind was very strong, and they were blown by the cold wind when they walked on the hill, and the stinging pain like a knife cut tested the extreme endurance of people.

Fortunately, the camp tent of the hill as a sentry post used four logs as a support point, otherwise it would have been blown over by a strong wind.

There were two people on duty in this camp tent as a sentry post, taking turns squatting to observe the surrounding situation, and when they saw Hua Mulan and others coming, they immediately straightened up with spears in their hands: "Tooth master!" ”

Hua Mulan observed the mental outlook of the two of them, nodded and asked, "Have you found any enemy situations?" ”

The person on duty replied loudly: "Not yet!" ”

Hua Mulan looked inside the tent, patted the two of them on the shoulder, and said to them: "Hold on for one night, tomorrow morning Benya will have people build a wooden house, build a kang in the house, and then you can collect some branches and wood to burn the fire at night to keep warm!" ”

"Thank you, Tooth Master!"

"But the person on duty must not leave his post halfway, his eyes must always be on the north, if because of your negligence to let the enemy approach without noticing, resulting in our army suffering huge losses, Benya must be dealt with by military law, no mercy!"

The two sentries immediately agreed loudly: "Yes!" ”

Coming down from the hill, Mulan took three soldiers with lanterns into the various camps to check the sleeping conditions of the soldiers.

After inspecting the stables and finding no anomalies, Mulan returned to her tent with the three soldiers.

The pro-soldier is a person from Huajiabao, Hua Mulan knows his roots, although he is five big and three thick, he is very clever, she commanded: "Oiran, pour tea!" ”

Oiran agreed, and brought Mulan and the three soldiers a steaming bowl of tea each.

Hua Mulan picked up the tea bowl and said to the three of them, "Let's talk while drinking tea!" Huahai, early tomorrow morning, you send five people to cut down some trees and set up the sentry post on the hill, the wind on the hill is too strong, and the camp tent will not last long before it will be blown down! In the evening, I went to the top of the mountain next to me to have a look, where the view is wide, if there is no fog, you can see far away, there are some rocks on the top of the mountain, you send five other people to the top of the mountain to build a beacon, collect wood and pile it on the beacon tower, pour fire oil on the wood, prepare the fire, and be able to light the beacon fire at any time! ”

There are three things in Mulan's teeth, one of which is all from Huajiabao, counting Mulan and the pro-soldier Oiran, a total of twelve people are from Huajiabao, and the villagers can take care of each other together, and they can unite together to protect themselves and not be bullied, which is also a common phenomenon in the army.

Hua Hai hugged his fists and agreed: "Yes, tooth master!" ”

Hua Mulan instructed the other two soldiers, Wang Liang and Chu Qingshan, "Tomorrow, the two of you get up early, take a few people to cut down some thorn branches, weave baskets, cut down trees to make flat poles, we have to prepare tools first to build a fort!" We also have three sleds, and after weaving the baskets, let the brothers go to the foot of the nearby mountain to pick up stones, carry the stones in the baskets, load the sleighs, and drive the horse-drawn sleighs to carry the stones to the hills! ”

Speaking of this, Mulan's face became serious: "We are the closest to the area controlled by the Flexible People here, there should be frequent Rouran Rangers nearby, we will soon be discovered by the Rouran Rangers when we appear here, after the news is transmitted back to Shengle City, the Rouran Cavalry there is likely to attack us, so we don't have much time, we must build this Nantian Fort in the shortest possible time!" As long as the Nantian Fort is built, we will have a defensive force, and we can block the attack of most of the Rouran cavalry with a small number of troops! ”

The three soldiers clasped their fists together and agreed: "Yes, Tooth Master!" ”

After the meeting, Mulan washed her face with the hot water from the sea of flowers, soaked her feet again, and warmed her body a lot.

Mulan was soaking her feet while thinking about her thoughts.

"Brother Junsheng, I don't know if you have arrived in Shanwu County, even if you haven't yet, you should arrive tomorrow, right? Be sure to take care of yourself and return to the Jinling camp safely with your brothers! ”

After soaking her feet, Mulan spread a wool blanket on the marching bed, wrapped in a woolen coat given to her by Zhao Junsheng, covered with a thick sheepskin mattress and quickly fell asleep.

Early the next morning, before dawn, the pro-soldier Hua Hai blew the horn to get up, and Hua Mulan watched the soldiers run out of the camp tent at a fast speed and line up in front of her.

"Although we have come out of the camp to camp here, but the drill can not be relaxed, the morning exercise still has to be carried out, the man has already gone to cook, the meal will be opened after an hour, our morning exercise will be practiced for an hour as usual! Huahai, it's up to you to give orders for today's morning exercises! ”

"Yes!" Hua Hai agreed, walked out and shouted to the soldiers: "Everyone listen to my orders, keep the queue neat, and spread out····· Now for the drill of assassination, stab! ”

"Hah-"

Hua Mulan watched the soldiers' drills for a while, and walked towards the hill with her own soldier Oiran.

Oiran followed her and said, "Miss, I'm afraid that we will delay a lot of time in building the fort, and the progress of the drill will definitely be delayed. ”

Hua Mulan sighed: "This is also a matter of no choice, I can only speed up the progress of building the Nantian Fort, and then shorten the rest time of the soldiers!" ”

After breakfast, Mulan arranged a guard and then took her soldiers to start labor, and after she began to do it, she found that the actual difficulties were much more than she imagined, the first to cut the rattan basket was not very smooth, the frozen rattan was too laborious in the weaving process, and it was not easy to shape, and finally someone thought of a way, put all the cut rattan on the fire and roast, let the ice and snow frozen on it melt, and soften the rattan, so that it was easy to prepare, and this solved the problem.

Then a new question arose, many of the stones at the foot of the mountain were covered with ice and snow, and were frozen by ice, how could they be so easy to move?

However, human wisdom is infinite, some people have thought of two ways, using stones to smash the frozen small stones, and using the principle of rods and bars to use wooden bars to pry the big stones loose, and then carry them.

In the process of transporting the stones, a new problem arose, because of the snow and ice, people had to walk carefully from the foot of the mountain to the hill on this journey, it was very slippery, and the horse-drawn sleigh could not go up at all, it was too slippery.

In the end, Mulan had to order a clumsy method of having the soldiers use knives to cut tooth marks on the ice of the hillside, while reducing the number and weight of the stones loaded each time, so that the horses could barely pull the sled up the hill.

After three days of working in a row, Mulan and her soldiers pulled all the stones for the construction of Nantian Fort to the hill, and at this time, the sentry pavilion wooden house on the hill and the beacon tower on the top of the hill had already been built and piled up.

The next thing is really fatal, the wall needs to use stones, mud and wood, the stone is already equipped, the wood is easy to do, just send people to cut down, but in this ice and snow to dig out the soil and pour water and mud into mud is not a simple matter.

The outside temperature is too low, and the water will quickly form ice cubes when poured down, so how do you turn the mud into thin mud? If the mud is not used in a short period of time, it will freeze quickly.

Hua Hai proposed to Mulan: "Tooth Master, let's let the soldiers dig up the ice and get the soil first, let's build a camp tent next to this, light a fire in the camp tent, and boil water with a cauldron while mixing with the mud, and the mud that has been reconciled is immediately proposed to be used!" ”

Hua Mulan thought about it for a while, nodded and said, "Now it's only like this, let the brothers work!" ”

Under the leadership of Mulan, the three tooth owners and the soldiers smashed the ice together, and it took a lot of work to dig out some dirt from under the ice, and a basket of soil was carried into the camp tent by the soldiers with flat poles, and someone immediately poured hot water into the soil.

Several people were in charge of the mud, and after pouring the mud into the barrels, they were carried by special people to the place where the fortress was built.

Masons are a handicraft job, not everyone can do it well, these soldiers are not heavy soldiers, the Han people of the heavy soldiers have a low status, and they are mostly engaged in various industries, it is not too simple to find a few masons and carpenters, but it is not easy to find a few masons and carpenters from these soldiers of the town.

No one knows how to do the work of a mason, so Mulan had to take the soldiers to drive the ducks to the shelves, not to mention the craftsmanship, as long as the fortress walls can be stacked, as long as they can be sturdy, it doesn't matter if it looks good or not.

Without a mason's brick knife, Hua Mulan and others used a wooden shovel to shovel up the thin mud to build the wall, and they first filled the foundation trench dug in advance with a layer of ten centimeters thick mud, and then placed the irregular stones flat on the thin mud, and the stones were placed tightly.

Then lay a layer of thin mud on top of the placed stones, so that the gaps between the irregular stones can be filled, and there will be no holes in the walls.

The mud should not be too thin, nor too dry, it will be easy to flow away if it is too thin, and it will not be sticky if it is too dry.

After two hours of drying, the foundation was raised, and in this weather, the mud quickly froze along with the stones.

Hua Hai came over with a block of mud and looked at it, and said to Hua Mulan, who was building the wall: "Tooth master, I think this foundation is very good!" ”

Hua Mulan took a wooden shovel and held a stone and asked Hua Hai, "Is the wall crooked?" ”

"No, it's straight, as long as you don't lean left and right when you build up, it should be fine!"

Mulan thought for a while and said, "I remember when I saw a mason building a wall, he had to hang a vertical line on the wall, so as to grasp the proportion and not build the wall crookedly. ”
