The three days of the New Year passed quickly, and the sky was sunny after the snow, although the cold weather at the moment was not conducive to digging ditches and building embankments, but time was not waiting for anyone, Lin Jue still decided to start construction as soon as possible.

I have been here for more than two months, and I have done a lot of things and completed a lot of ideas. However, if the matter of reclamation and reclamation of land and dam digging is not implemented, all the previous operations will be in vain. Cottages are not self-sufficient, and this thriving scene will not last long.

On the fourth day of the Lunar New Year, in the snow, thousands of soldiers and civilians gathered at the northern end of Luoyan Valley with large flags.

At the northern end of the valley, on the south shore of a large lake formed by the rainwater collection of several mountain peaks, the groundbreaking ceremony was officially held. As the commander-in-chief of the project, Lin Jue delivered an enthusiastic and encouraging speech. After that, several soldiers of the Luoyan Army showed a huge engineering rendering in front of everyone.

The picture depicts a scene of beautiful mountains and rivers. A long embankment stretches across the valley, and a pool of blue water ripples in the embankment, and several fishing boats with nets are drawn on the water. The green willows above and below the embankment are still around, and the scenery is beautiful.

In the valley below the dam, several small lakes are connected by a jade-like river. On both sides of the river are large green fields overgrown with crops. The ditches are intertwined into a network like veins of leaves, and each ditch leads to the great river in the middle. The river meanders down the middle of the valley and pours into the gorge northeast of Laojun Mountain in the south.

This scene is really eye-catching in the middle of the ice and snow, but everyone knows that this is the scene of the valley that the military advisor has painted for himself in the spring of the coming year. It's a scene that makes people feel thrilled just by looking at it. No kind of agitation is actually more effective than this rendering. Thinking that they would live in such a scene in the future, the vast number of soldiers and civilians were full of fighting spirit and enthusiasm.

This picture was painted by Green Dance for several nights under the guidance of Lin Jue. The girl's heart is already very fine, and the scenery in many places on this map Lin Jue didn't point out at all, so she drew it out by herself. The landscapes, trees and flowers are vivid, and there is quite a bit of talent for Danqing's skillful hands.

Lin Jue spent a quarter of an hour explaining his idea in detail. The first is the upstream dam. Originally, Lin Jue's idea was to build a three-tiered dam to intercept rainwater and snow water layer by layer, so as to ensure that the valley would not be affected by floods and droughts. But during this time, Lin Jue abandoned this idea after careful consideration.

First, the construction of the embankment was too large, and the valley of Luoyan Valley was more than three or four miles wide. It is not easy to build a dam that can hold back water. What's more, the construction of three dikes would be an impossible task.

Second, after the field trip, Lin felt that the amount of water in this valley was very large. The rain and snow on the two peaks on either side of the mountain are enough to form a huge current, not to mention the open pattern at the northernmost part of the valley. Rainwater from several peaks collects into the valley, creating a huge flow of water. Under such circumstances, it is not practical for a dam to hold back the flow of water, and a dam made of earth, stone and wood cannot withstand the pressure. If a dam breaks, it's a catastrophe. The flood would sweep everything in the valley clean.

In view of this, Lin Jue changed his thinking. Only one dam was built, and the purpose of this dam was not to hold back water, but to regulate drought and flood reservoirs. A certain amount of water can be stored, but never more than a limit. This embankment Lin Jue positioned it as a low flat dam with a height of only one zhang and a width of more than ten zhang. Flood mounds will be set aside on both sides and in the middle of the dam. If the water level exceeds 8 feet, the three flood mounds will immediately discharge flood water downwards without causing damage to the levees.

Downstream of the embankment, a north-south flood channel, or miniature man-made canal, was dug along the low-lying area in the middle of the valley. All excess rainwater will flow south through the canal into a deep valley northeast of Laojun Mountain.

In the same way, rainwater collected on the mountain walls on both sides of the valley will be channeled into the river in the middle by digging dozens of ditches. This is both an irrigation network and a flood discharge network. During the flood season, all excess water will be drained through artificial canals. Form a complete water supply and drainage system.

The benefits are not only these, the artificial river can be used by boats, and the mill waterwheel can be built where the water flows, these are all conditions that can be convenient for the people. Moreover, compared to the construction of a dam, the labor and effort required to dig a ditch is much smaller. Especially when there is a huge amount of work to be done on the wasteland, saving more labor and time can ensure that the goal is achieved as soon as possible in the spring when the flowers are blooming.

The military advisor's explanation made the soldiers and civilians understand the purpose and importance of the construction of the dam and ditch. Lin Jue's voice fell, and some people had already begun to shout.

"Strategist, let's get to work, we can't wait to see the day when the dam is built and the river is dug. I can't wait to see the bumper harvest of 10,000 hectares of fertile land this year. In fact, the military advisor doesn't need to tell us so much, the military advisor only gives orders. ”

"Yes, the military advisor gives the order, we can't wait."

Lin Jue laughed, knowing that the enthusiasm of the people had been mobilized, and he was holding back his strength at this moment. This is a good time for big construction. At the sound of an order, the people rushed to the location of the dam divided by lime lines, waved their tools and began to move.

However, despite the enthusiasm of the people, they had no idea how difficult it would be. As soon as I got started, I encountered a problem. They couldn't dig through the frozen ground. It is under the embankment above, and the land is moist all year round. In such weather, it is the coldest time. The earth and water on the ground froze together and became a hard lump of ice, and even an axe could only cut a few marks on the ground.

Lin Jue didn't expect this problem of the location either. It's mostly a matter of seasonality. If it's spring, summer and autumn, it's not a problem at all. But Lin Jue can't wait for the frozen soil to thaw, because the season waits for no one. Before the sowing season, dams must be built, ditches must be dug, and acres of land must be cultivated for cultivation. Otherwise, the chain reaction is that it cannot be cultivated in time, resulting in the inability to solve the basic food supply in the cottage, and finally leading to the collapse of the cottage.

Facing the soldiers and civilians who were all doused with a scoop of cold water, Lin Jue felt a huge pressure. At this moment, he must provide a solution, he is angry, so many people are looking at him, he must come up with a solution.

But where can Lin Jue do anything? This is not the earth in the afterlife, where there are so many powerful machines that can break through the frozen soil, and there is not much room for maneuver here. But no matter what, Lin Jue couldn't let it go, he thought for a moment and proposed a method that even he felt was unreliable: burn it with fire!

Lin Jue's method was to spread hay racks on the demarcated location of the embankment and start a fire on trees on it. The frozen soil is thawed by fire, and then dug down layer by layer. This method is so stupid that even Lin Jue himself feels embarrassed after saying it.

However, no one at the military and civilian levels raised any questions, and they seemed to have decided that the tactics of the military division would definitely work. When Lin Jue proposed a solution, thousands of people immediately took action, mowing the grass, transporting the trees, and piling a large amount of firewood and grass in a range of more than ten zhang wide and three miles long before dark.

After dark, a fire dragon burned horizontally at the northern end of the valley floor, forming a huge wall of fire. This scene made the sentinels on the top of Beishan Mountain, which was more than twenty miles away, see it clearly. I thought there was a big wildfire here.

The fire burned overnight, and at dawn the entire ground was covered with heat. The charcoal fire, which had not yet been extinguished, was already emitting a scorching heat. Lin Jue was nervous and ordered to try to excavate in Dongshou, and a citizen used an iron shovel to stick into the soil, and stepped on the force with his foot, the iron shovel completely sank into the soil, and a large piece of steaming soil was dug out. At this time, everyone was overjoyed and rushed up to start digging. Soon a layer of frozen hard soil is stripped off of the surface, and the alluvial black sand is laid below. Two feet below the ground, the dirt no longer froze. Even if the heat doesn't penetrate this deep, there's no need to worry.

Lin Jue was very happy, but he didn't expect this stupid method to come true. Although it was delayed for some time, it was not stopped by this hard bone after all. Lin Jue can be regarded as a good learner, and he still has to dare to think and dare to do everything. My previous worries were actually superfluous, and the method was stupid, but fire can melt ice, this basic idea is no problem, and it is inevitable that it will be effective. Of course, this is also due to the fact that the location of Funiu Mountain is not too far north, and the temperature is not so cold. After all, the location here is still more than 300 miles away from Bianliangdu, and it actually only belongs to the Central Plains. If it is the real northland, under the extremely cold temperature, there is a thick layer of permafrost under the land, then there is no way.

After breaking through these obstacles, the next progress is much faster. More than 3,000 people dug for three days, digging a huge six-foot deep trench and digging into the rock formations below, which met the requirements of the dam foundation. This also proves from the side that this valley is very suitable for farming, the original ground of the valley is the rock layer below, I don't know how many years of alluvial accumulation of soil, grass roots and fallen leaves, finally covered the whole valley with a thick layer of fertile soil. This soil is the most suitable for growing crops.

The next step was to dig holes in the rock and plant huge pieces of wood that had been embalmed with charcoal fire to form a ten-row frame structure made of logs at intervals of one zhang. The next step is to ram the triad soil mixed with lime into this frame, layer by layer, layer by layer, layer by layer, after the layer of tamped triad soil solidified as hard as a rock.

In response to that sentence, the nine-story platform rises from the soil, and the base of this huge embankment grows higher day by day in the labor and sweat of thousands of people. Although it could only increase by less than one foot per day, by the time Lin Jue and Gao Muqing led their troops to leave the cottage to participate in the meeting, the entire dam was already six feet high, like a huge city wall across the valley between the two mountains.

Before leaving, Lin Jue handed over the burden of the chief commander of the project to Ruan Pinglai, and explained the follow-up procedures. After the dam reaches the designed height of one zhang, the need to build a breakwater with bluestone on the outer layer is to build a breakwater. And lay willow stakes on the ground below the inside to protect against wind and waves. When spring comes, these willow trees will also sprout and live, and then they will become a green willow causeway just like the painting painted by Green Dance.

Although, this time to participate in the Funiu Mountain Alliance, Gao Muqing and Lin Jue almost transferred all the soldiers and horses of the cottage. This will affect the progress of the project to some extent, but it is also helpless.
