Edwin turned around the shallow pit again and again. Nicole was worried about whether the old scholar would faint if he turned like this. As soon as she wanted to stop, she heard him say, "Victor, what are you digging is a reservoir?"


    "Ah? It''s a reservoir!"


    Nicole is a little disappointed. Reservoirs are not new in the human kingdom, especially in areas lacking rivers and lakes. For example, the Neville Kingdom has built many reservoirs in mountain fortresses to store rainwater for human and livestock drinking and watering vegetable fields. In fact, Nicole is also leading people to dig a reservoir. There are only a few mountain streams in her territory. If she uses water at ordinary times, there will be no problem. But tens of thousands of young people will be stationed here soon. If so many people have to go to the mountain stream to drink water, it will be too troublesome. Therefore, Nicole and thousands of people will build ten camps here, and reservoirs will be built in each camp.


    Victor pulled Nicole and Edwin from their busy affairs and said they would give her a gift, which could turn her territory into a rich and rich place. Nicole and Edwin came here in high spirits. Unexpectedly, it was a reservoir. Although disappointed, it was thought that this was Victor''s intention, and Nicole was sweet in her heart.


    "It''s very kind of you, victor!"


    Edwin looked up and rolled his eyes. Judging from the size of the pool and the water in it, it was obviously dug before Nicole took office, and Nicole couldn''t see it at all. It''s really dizzy! Victor had many amazing ideas, but it was always planted in common sense. Edwin had to explain the advantages and disadvantages of the reservoir in detail.


    "Victor, the area of cultivated land is related to the water source, but the rainwater stored in the reservoir can be used for growing vegetables, but if you plant wheat, it''s useless to dig a bigger Reservoir! In fact, the larger the reservoir, the faster the water dries. The main function of the reservoir is to collect rainwater, but the rainwater falls evenly on the ground. Therefore, small reservoirs are easy to fill, while large reservoirs have no water If you can''t fill it up, the water will volatilize more easily. In addition, the rain is unstable, and the water in the reservoir is sometimes dry. It''s OK to irrigate the vegetable field. If it''s used for wheat with a longer growth cycle, it''s not enough. Let''s say, what do you think when you go so far to dig a pool? "


    Victor smiled: "master, I really can''t hide it from you. I dug this pool to increase cultivated land. I didn''t realize the importance of the lake until I took Pinghu back, so I want to dig a lake here by manpower, which can increase at least 20000 mu of wheat fields. Unfortunately, a heavy rain failed my plan."


    "This is not surprising. In the early days, some people wanted to use reservoirs to increase the area of cultivated land. They all encountered the same dilemma. Now no one has done so." Said Edwin.


    Nicole also comforted: "Victor, the reservoir you dug is still very useful. Repairing it can add thousands of mu of vegetable land."


    Victor cried and said, "I didn''t go so far to dig a hole to grow vegetables!"


    This is also where Edwin wondered. The puddle is not in the hinterland of Randall''s territory, but in the southeast corner of Nicole territory, more than 70 kilometers away from Victor''s brick kiln village. Victor should not choose this position whether it is to borrow earth to make bricks or dig lakes to make fields.


    "There are two reasons for choosing here. One is that it is close to the water source, and the other is that the terrain here is relatively high." Victor pointed to the South and continued: "You see, it''s only 6 kilometers away from Jinshui River. Jinshui River flows from west to East, indicating that the terrain in the west is higher than that in the East. I plan to dig a huge reservoir here, and then build a ditch to the southwest to connect Jinshui River and reservoir. With a stable water source, the reservoir will become a lake, enough to irrigate tens of thousands of mu of cultivated land."


    No one in the world has ever put forward the concept of artificial lake and river. Edwin and Nicole were shocked by Victor''s grand plan to make the sea change. Nicole stared at Victor''s exquisite side face, her bright eyes were full of worship and admiration, while Edwin fell into deep meditation.


    "Two questions." Edwin woke up from his meditation and said: "First, no one has ever thought about the Jinshui River except the Borui Kingdom, and the fish man can''t get around the difficulty. If you want to draw water from the Jinshui River, you must eliminate the fish man on the river bank. It took the Borui Kingdom and the fish man 80 years to build Alexandria, and until now they are still fighting with the fish man. Second, the water of the Jinshui River is enough to submerge the lake, and the river flows eastward along the lake and straight into the Heihe River A large area between them has become a swamp and will also be occupied by fish people. This is tantamount to opening up territory for fish people. "


    Victor nodded and said: "Master, you are very considerate. However, in my opinion, these are not problems. First of all, the riverside fish people have experienced the ant disaster. I have witnessed several wars between the fish people and the ant colony, and at least more than 20000 fish people have been wiped out. The riverside fish people of the chebman family have also been seriously damaged. It is said that more than 20000 fish people have been swallowed by the ant colony. In this area, the number of fish people has decreased sharply and has been destroyed I''m not worried. "


    In just one year, ant people have achieved the results of 80 years of war in Borui Kingdom, because fish people and ant colonies are large groups of combat, and human beings do not have the logistics ability to support large groups of combat, nor can they bear the huge casualties of ordinary soldiers. Human beings take knights as the core, trainee knights as the backbone, elite soldiers as the auxiliary, fight against the enemy''s living forces, and then rely on the castle for rest , by constantly encroaching on the enemy until victory.


    Fish people have a poor memory. No matter how much they suffer, they will launch a counterattack as long as they gather enough. In the face of this situation, the human army chose to avoid its edge and come out to kill fiercely after the fishmen dispersed. Many fish people die and live, so it took Borui Kingdom 80 years to minimize the influence of fish people. Unlike ant colonies, they choose just the front. Therefore, the fish man with short memory is sad.


    After Edwin found out the truth of the matter, he couldn''t help sighing: "ant people without individual consciousness are really a nightmare for all intelligent races!"


    Victor smiled and continued, "master, the second problem can be solved. We can build a huge city gate at the junction of Jinshui River and ditch."


    "City gate?"


    "Isn''t there a gate made of fine iron in the city gate of Heibao? We can use that gate to adjust the water volume. When the lake water level drops, we pull up the gate to discharge water. When the lake is full, we put down the gate to block the river. I call this kind of city gate sluice."


    "Wonderful! No! It''s a genius''s idea!" Edwin muttered to himself and said excitedly, "what are you waiting for? Let''s go to the river bank!"


    Victor, Nicole and Edwin took a team of elite guards to the Jinshui River. There were indeed three or two big fish and small fish on the beach. When those fish people with teeth and claws were shot by the guards, Edwin was less than 50 meters away from the Jinshui River.


    Looking at the turbulent Jinshui River, Edwin said to victor, "you just said that neither of the two problems is a problem. What is the real problem?"


    "Time!" Victor stepped forward and stood side by side with Edwin and said, "fish people breed and grow fast. They will become a big trouble in four years at most. We must complete this project as soon as possible. In addition, digging huge pits will also be affected by rain, so we must concentrate manpower and dig out the huge pits first."


    Edwin was silent for a moment, turned his head and said, "Victor, you designed the ditch and artificial lake not only to help Nicole? Nicole was not the Lord here when you dug the pit. And the design of ditch and reservoir can be copied continuously, can''t it?"


    No one is desperate! Victor sighed in the bottom of his heart. He didn''t expect that Edwin saw through his artificial river plan from only a small amount of information and disrupted his layout. However, he simply said frankly: "Master, you are right. With the help of the first artificial lake, I can continue to build ditches and artificial lakes. Finally, an artificial river will run through my territory and add millions of mu of cultivated land to me."


    "Millions of Mu!" Nicole covered her mouth and exclaimed.


    Edwin said with burning eyes: "far more than that! This artificial river can also run through the whole man horse hill and increase tens of millions of mu of cultivated land!"


    Nicole is a little dizzy. Her territory is 3000 square kilometers in size, but with the help of mountain streams, up to thousands of mu of cultivated land has been reclaimed, and the land reclaimed by the York family and the vassal family is only tens of millions of mu. Victor said to increase hundreds of thousands of Mu of cultivated land in her territory and turn it into a fertile land. It''s really not a lie.


    Nicole looked at Victor affectionately, but Edwin said seriously, "Nicole! If you don''t want Victor to be in danger, this matter must not be spread!"


    Nicole was surprised and said flatly, "I will never say it!"


    "Victor, let''s go! There are still many details to talk about!" Edwin took victor and left.


    In the following ten days, Edwin left his business and investigated the terrain, streams, mountain streams, rivers and lakes of Randall''s land with victor. They ate and lived together. After continuous discussion and research, they improved the artificial river plan. Finally, the old scholar returned to Heibao town with a large pile of scrolls.


    At Rose Manor, Sylvia held her chin and stared at the huge map on the wall.


    "Victor and I call this artificial river project artificial irrigation system. It is mainly composed of sluice, ditch and reservoir. The principle is that sluice controls water, ditch diversion, discharge and reservoir storage. Let me talk about sluice first.


    The most important sluice is located by the Jinshui River. On the surface, it is no different from the iron gate of the city gate. It is also made of refined iron and pulled by winch and iron cable. However, for safety reasons, I designed a triple gate. The first gate is the main gate and the other two gates are standby. Although the refined iron is corrosion-resistant, it still needs to be replaced after a long time. The gate below the gate is made of refined iron The fence prevents fish people from entering the ditch. In order to resist the harassment of fish people, a castle and two seven meter high walls need to be built around the gate to facilitate the entry and exit of soldiers. I have drawn the specific design sketch.


    In addition to this large sluice, there are many small sluice gates to be built. Don''t worry, these small sluice gates are very simple. They can be built with stone slabs and don''t cost much. As for the location of the sluice gate, we''ll talk about it later. "


    Sylvia breathed a long sigh of relief. Edwin left his job at the entrance of the Everglades and ran back to come up with such a shocking plan. If every control gate did so, he could not afford to pack and sell the York family.


    Edwin continued: "then there is the artificial ditch. According to Victor''s design, the main ditch connects the first reservoir. It is 3 meters wide and 6 kilometers long. Every 500 meters, a step goes down, with an average depth of 1.5 meters and an overall drop of 4 meters. In order to prevent siltation, the ditch is built with green bricks. On both sides of the ditch, river embankments 3 meters above the ground should be piled up.


    The ditch spreading from the first reservoir is relatively simple. It is 4m wide and 1.8m deep. A small reservoir will be built about 20km. The overall drop is 12M, and the river embankment is 1.5m higher than the ground. Victor means to lay the bottom with green bricks. I think it''s OK to use crushed stones. There are no large stone mines in the man horse hills, and there are still a lot of crushed stones. "


    "Then there is the reservoir. The first reservoir is 200 mu in size and 20 meters in depth, while the other reservoirs are 50 mu in size and 8 meters in depth. I calculate that about 500 reservoirs are needed. The ditch behind the last reservoir directly leads to the Heihe River. Then the whole artificial river has a total length of 1100 km, runs through renmachu mausoleum, flows from southwest to northeast, and finally flows into the Heihe River. A three-dimensional river is formed between the Heihe River and the artificial river In the angular area, 70 million mu of cultivated land will be added. By the way, there will be a large number of fish, shrimp and aquatic products in artificial rivers and reservoirs. "


    "70 million mu, 70 million mu... Dear Victor, you really gave me a problem!" Sylvia murmured to herself, caressing the white corner of her forehead. A moment later, she looked up and said: "Uncle Edwin, how dare you think about digging out more than 1000 kilometers of rivers and more than 500 lakes? How much manpower? How much time? How much material resources do you think we York family can do it? Gambis can do it with the strength of the whole country? Farmers need to cultivate land, soldiers need training, and have time to dig rivers every day? Despite the artificial irrigation system The prospect of is very attractive, and I can''t agree! "


    Edwin shook his head and laughed and said: "Victor is brilliant and a real genius. After in-depth communication with him, I learned that his farming and animal husbandry system and artificial water conservancy irrigation system complement each other. The farming and animal husbandry system can produce enough food to allow farmers to engage in water conservancy projects. Water conservancy projects can increase the number of farms and villages, expand the family''s actual control over the territory and solve strange problems The problem of animal invasion, so as to ensure the continued implementation of the agricultural and animal husbandry system. " With that, Edwin went to the map and pointed to the mountains on the west side.


    "If the artificial ditches are built directly, the family really can''t bear it. Therefore, Victor suggested to build a large reservoir first. You see, this is the mountain area on the west side of Renma hill. There are many streams and mountain streams flowing out from here. They are mainly springs in the mountain area. Due to the small amount of water, they soon infiltrate into the ground and can''t irrigate farmland. However, when it rains, the amount of water in the mountain area It rose sharply and surged down the stream, directly into the Heihe River from a low place.


    Victor believes that these waterways not only show us the height of the terrain, but also are natural ditches. Large reservoirs are dug in the middle of these ditches from west to East. Once it rains, mountain streams and rainwater will fill the reservoirs into small reservoirs. Building small sluice gates in the ditches behind the reservoirs can prevent floods and alleviate drought. This design alone can be increased 20 million mu of cultivated land will produce more food and accommodate more people, and then slowly build a main ditch in the north-south direction. When the water conservancy project is completed, you will find that the whole human horse hill is covered with ditches and waterways, and there may be hundreds of millions of mu of cultivated land! "


    Sylvia''s blue eyes are full of color. Victor''s idea is very clear. First, build a reservoir in low-lying areas, build East-West small ditches and small sluice by using mountains, rivers and streams, complete the transformation from reservoir to small reservoir, and then slowly excavate the main ditch in north-south direction, taking the small reservoir as the hub to realize the intersection of many small ditches and main ditches Finally, such a magnificent water conservancy project was completed in pieces. What''s the point of digging a reservoir? The small sluice is just a stone slab a few meters wide. It can be said that Victor''s design minimizes the cost and brings benefits that Sylvia can''t refuse.


    "Wonderful!" Sylvia took a deep breath and said, "Victor thought what his predecessors did not dare to think. Our York family will do what their predecessors did not dare to do!"


    Edwin said with a smile, "that''s it!"
