Edwin drove around the shallow pit, Nicole was a little worried that the old scholar would faint if he turned this way, and listened to him as soon as he wanted to stop him. Victor, did you dig a reservoir?"

"Ah? It's a reservoir!"

Nicole was a little disappointed. The reservoir is nothing new in the human kingdom. Water storage tanks are quite common in areas lacking rivers and lakes. For example, Naville Kingdom has built many storage tanks in mountain fortresses to store rainwater for humans and animals to drink and to irrigate vegetable plots. In fact, Nicole is also leading people to dig a reservoir. There are only a few mountain streams in her territory. If it is normal, there is no problem with water. But tens of thousands of young people will be stationed here soon. If so many people have to run to the mountain stream to drink water, it will be too much trouble. Therefore, Nicole took thousands of people to build ten camps here, and each camp must build a storage area. pool.

Victor pulled Nicole and Edwin from the busy business, and said that he would give her a gift, which could turn her territory into a land of fertility. Nicole and Edwin were eager to rush Come here, didn't expect turned out to be a reservoir. Although disappointed, I can think of it as Victor's heart, and Nicole's heart is sweet.

"Victor, you are so kind!"

Edwin looked at the sky with two eyes, rolled the eyes. Judging from the size of the pond and the accumulation of water in it, it is obvious that this was dug before Nicole took office, and Nicole can't see this at all. It's really fascinating! Victor has many amazing ideas, but they are always based on common sense. Edwin had to explain the pros and cons of the reservoir in detail.

"Victor, the area of ​​arable land is related to the water source, but the rainwater stored in the reservoir can be used to grow vegetables, but if it is to grow wheat, no matter how large the pond is dug, it is useless! In fact, the reservoir It cannot be large, the larger the water is, the faster the water will dry. The main function of the reservoir is to collect rainwater, but rainwater falls evenly on the ground. Therefore, small reservoirs are easy to fill, while large reservoirs cannot be filled. , The water is easier to volatilize. In addition, the rain is not stable, the water in the reservoir sometimes dries, watering the vegetable field is fine, if it is used for the wheat with a longer growth period, it will not be enough. Come on, you ran like this What did you think about digging a pond far away?"

Victor smiled: "Master, I really can’t hide from you. I did dig this pond to increase farmland. I only found the lake after I took it back to Pinghu. So I want to use manpower to dig out a lake here, so that at least 20,000 mu of wheat fields can be added. Unfortunately, a heavy rain made my plan fail."

"This is not surprising In the early days, there were people who wanted to use water storage tanks to increase the area of ​​arable land. They all encountered the same predicament, and no one has done this anymore.” Edwin said.

Nicole also consoled: "Victor, the reservoir you dug is still very useful. If you repair it, you can add thousands of acres of vegetable land."

Victor didn' t know whether to cry or laugh, and said: "I didn't dig a hole so far to grow vegetables!"

This is also where Edwin was puzzled. The puddle is not in the hinterland of Randal, but At the southeast corner of Nicole Territory, it is more than 70 kilometers away from Victor’s Brick Kiln Village. Whether it is taking soil to make bricks or digging lakes to make fields, Victor should not choose this location.

"There are two reasons for choosing here, one is that it is close to the water source, and the other is that the terrain is relatively high." Victor pointed to the south and continued, "Look, it is only 6 kilometers away from the Jinshui River. The Jinshui River flows from west to east, indicating that the terrain of the west is higher than that of the east. I plan to dig a huge reservoir here first, and then build a ditch in the Southwest direction to connect the Jinshui River and the reservoir, and have a stable water source for storage. The pond becomes a lake, enough to irrigate tens of thousands of acres of arable land."

In this world, no one has proposed the concept of artificial lakes and rivers. Victor dared to call the sea a majestic one. The plan was shocked. Nicole stared at Victor's exquisite profile, and his shiny eyes were full of admiration, while Edwin fell into deep contemplation.

"Two questions." Edwin woke up from meditation, and said: "First, no one but the Borui Kingdom had the idea of ​​Jinshuihe. The murlocs are difficult to overcome. I want to. To divert water from the Jinshui River, the murlocs on the river bank must be cleared. The Borui Kingdom and the murlocs have been fighting for 80 years to build Alexandria, and they are still fighting the murlocs. Second, the water of the Jinshui River is enough to flood the lake, and the river water runs along. The lake spreads eastward, straight into the black river, and a large area in the middle becomes swampland, which will also be occupied by murlocs. This is tantamount to opening up territory for murlocs."

Victor nodded, said:" Master, you have considered very well. However, in my opinion, these are not problems. First of all, the murlocs on the riverbank have experienced an ant plague. I have witnessed several battles between murlocs and ant colonies. There are at least 20,000 murlocs. Annihilated. The riverbank murlocs of Chebman’s house were also severely damaged. It is said that more than 20,000 murlocs were swallowed by the ant colony. In this area, the number of murlocs has dropped sharply, which is no longer a concern."

In just one year, Ant-Man has achieved 80 years of victory in the Borui Kingdom, because the murlocs and ant colonies are fighting in large groups, and humans do not have the logistical ability to support large groups, nor can they withstand ordinary soldiers. Huge casualties. Human beings take Knight as the core, trainee Knight as the backbone, and elite soldiers as the auxiliary to fight the enemy's vigorous force, and then rely on the castle to rest and reorganize, and continue to erode the enemy until victory is achieved.

The murloc’s memory is extremely poor. No matter how badly they suffer, they will launch a counterattack as long as they gather enough. Faced with this situation, the human army chose to avoid its edge and waited for the murlocs to disperse before coming out to kill. Many murlocs died in battle and many were born, so it took the Kingdom of Borui for 80 years to minimize the influence of murlocs. But the ant colony is different, they choose to just face. So, the murloc who didn't have a long memory was sadly reminded.

After Edwin figured out what happened, he couldn't help sighing: "Ant-man without individual consciousness is really a nightmare for all intelligent races!"

Victor laughed and continued: "Master, The second problem is also easy to solve. We can build a huge city gate at the junction of the Jinshui River and the ditch."

"City gate?"

"The city of Heibao Doesn’t the gate have a gate made of iron essence? We can use that kind of gate to adjust the amount of water. When the water level of the lake drops, the gate is pulled to let in the water, and when the lake is full, the gate is lowered to block the river. I call this kind of city gate control. Gate."

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

Victor, Nicole and Edwin brought a team of elite guards to the Jinshui River. There were three or two big fish on the beach, waiting for the murlocs of baring fangs and brandishing claws to be shot by the guards. Edwin is less than 50 meters away from Jinshui River.

Looking at the turbulent Jinshui River, Edwin said to Victor: "You just said that those two problems are not the problem, then what is the real problem?"

"Time!" Victor stepped forward and stood shoulder to shoulder with Edwin and said: "Murlocs reproduce fast and grow fast. They will be a big problem for up to four years. We must complete this project as soon as possible. In addition, digging huge pits will also be affected by rain. Therefore, we must concentrate our manpower to dig out the huge pit first."

Edwin was silent for a moment, then turned his head and said, "Victor, the ditches and artificial lakes you designed are not just to help Nicole? You dig them. Nicole was not the lord here at the time of the pit. And this design of ditches and reservoirs can be replicated continuously, right?"

No one is inexhaustible! Victor sighed from the bottom of his heart. He didn't expect Edwin to see through his artificial river plan from only a half-claw of information, and also disrupted his layout, but at this point, 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. Eventually an artificial river will run through my territory, adding millions of acres of arable land to me."

"Millions of acres!" Nicole exclaimed, covering her mouth.

Edwin said with scorching eyes: "Much more! This artificial river can also run through the entire Centaur Hills, adding tens of millions of acres of arable land!"

Nicole was slightly dizzy, Her territory is 3,000 square kilometers in size, but with the help of mountain streams, up to a few thousand acres of arable land can be reclaimed, and the land reclaimed by the York family and the vassal family is only tens of millions of acres. Victor said she wanted to add hundreds of thousands of acres of arable land to her territory, and it was not a lie.

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

Nicole heart startled, categorically said: "I will never say it!"

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

In the following ten days, Edwin left his business aside, and together with Victor, he investigated the terrain of Randal, including streams, mountain streams, rivers, and lakes. The two ate and lived together. After continuous discussions and discussions Research and perfect the artificial river plan. Finally, the old scholar returned to Black Castle Town with a lot of scrolls.

In the Rose Manor, Sylvia's chin propped up staring blankly at the huge map on the wall.

" Victor and I called this artificial river plan an artificial water conservancy irrigation system. It is mainly composed of control gates, ditches, and reservoirs. The principle is that control gates control water, and ditches divert and discharge water. Water, reservoir storage. Let me talk about the control gate first.

The most important control gate is located by the Jinshui River. On the surface, it is no different from the city gate iron gate. It is also made of iron essence, a winch. Pulled by the iron cable. However, for safety reasons, I designed the 3rd-layer gate. The first gate is the main gate, and the other two gates are spare. Although the iron essence is corrosion-resistant, it needs to be replaced after a long time. Below the gate. Use iron essence to create a fence to prevent the murlocs from entering the ditch. In order to resist the harassment of the murlocs, a castle and two seven-meter-high city walls need to be built around the gate to facilitate the entry and exit of the soldiers. The specific design sketches have been drawn up. .

In addition to this large-scale control gate, there are many small-scale control gates to be built. Don’t worry, these small-scale control gates are very simple. You can use stone slabs and don’t cost much. As for repairing the gates Position, we will talk about it later."

Sylvia's long relaxed, Edwin left the job of the Great Swamp entrance and ran back to come up with such a shocking plan. If every control gate does this, then I really can't afford to sell the York family as a package.

Edwin continued: “Then comes the artificial ditch. According to Victor’s design, the main ditch is connected to the first reservoir. It is 3 meters wide and 6 kilometers long. It has a step down every 500 meters, with an average depth of 1.5. Meters, the overall drop is 4 meters. In order to prevent siltation, the ditch was built with blue bricks. On both sides of the ditch, a river bank 3 meters above the ground should be piled up.

It’s relatively simple. It’s 4 meters wide and 1.8 meters deep. About 20 kilometers or so, a small reservoir will be built. The overall drop is 12 meters and the embankment is 1.5 meters above the ground. Victor means to pave the bottom with blue bricks. I think it is to use gravel. There is no large quarry in Centaur Hills, and there are still a lot of gravel."

"Then there is the reservoir. The first reservoir is 200 mu in size and 20 meters in depth, and the remaining reservoirs are 50 mu in size. It is 8 meters deep. I calculated that it would take about 500 reservoirs. The ditch behind the last reservoir leads directly to the black river. Then the entire artificial river is 1,100 kilometers in length, runs through the Centaur Hills, flows from the southwest to the northeast, and finally merges into the black river. river. A triangular area is formed between the black river and the artificial river, adding 70 million acres of arable land. By the way, there will be a lot of fish and shrimp aquatic products in the artificial river and reservoir."

"70 million acres , 70 million mu... Dear Victor, you really gave me a problem!" Sylvia murmured to herself while stroking her white forehead. After a while, she looked up and said: "Edwin Uncle, dig out More than 1,000 kilometers of rivers, more than 500 lakes, how dare you think? How much manpower is required? How much time? How much material resources? Do you think it can be done by our York family? Gambis can do it with the help of the whole country. Farmers need to farm and soldiers need training, so if you have time to dig rivers every day? Although the prospects of artificial irrigation systems are very attractive, I can’t agree!"

Edwin shook his head and laughed, and said: "Victor brimming over with talent, he is a real genius. After I had an in-depth exchange with him, I realized that his farming and pastoral system and the artificial water conservancy irrigation system are complementary, and the farming and pastoral system can produce enough food for farmers to have time to engage in water conservancy projects. , And water conservancy projects can increase the number of farm villages, expand the Great Family’s actual control of the territory, solve the problem of monster invasion, and ensure the continued implementation of the agricultural and pastoral system.” As he said, Edwin walked to the front of the map and pointed to the west side. Mountains.

"If the artificial ditches are built directly, the family is really unbearable. Therefore, Victor recommends building a large reservoir first. You see, this is the mountain area on the west side of Centaur Hills, where many streams and streams flow out. They are mainly spring water in mountainous areas. Because the water volume is relatively small and quickly seeps into the ground, it is impossible to irrigate farmland. However, whenever it rains, the water volume in mountainous areas soars, rushing down the stream, and directly sinks from low-lying places. Enter the black river.

Victor believes that these waterways not only indicate the height of the terrain for us, but also natural ditches after minor repairs. Large reservoirs are dug in the middle of these ditches from west to east. Once it rains , Mountain streams and rain will fill the pool into a small reservoir. Building small control gates in the ditches behind the reservoir can prevent floods and alleviate drought. This design alone can increase 20 million mu of arable land and produce more food , To accommodate more people, and then slowly build the main ditch running north-south. After all the water conservancy projects are completed, you will find that the entire Centaur Hills is densely covered with ditches and waterways. There may be hundreds of millions of acres of cultivated land!"

Sylvia’s blue eyes are full of colors. Victor’s idea is very clear. First build a reservoir in a low-lying place. Use mountains and streams to build small ditches and small control gates that run east-west to complete the reservoir. The transformation of small reservoirs, followed by the digging of the main ditch running north-south, using the small reservoir as the hub to realize the intersection of many small ditch and the main ditch. In the end, such a majestic water conservancy project was completed piecemeal. What's the point of digging a reservoir? The small control gate is nothing more than a stone slab a few meters wide. It can be said that Victor's design minimizes the cost, while the benefits Sylvia cannot refuse.

"Wonderful!" Sylvia took a deep breath and said: "Victor thought about what the predecessors didn't dare to think. Our York family will do what the predecessors didn't dare to do!"

Edwin said with a smile: "That's how it should be!"
