"The superstructures are all blue bricks?"

Scholar’s ​​discussion attracted Pierot’s attention. He heard Edwin say there: "Yes, this is better than The shore guard posts of the Borui Kingdom are much stronger, right?” In order to divide the murloc’s range of activities, the Borui people built many defensive posts on the banks of the river. The geological structure of the river beach cannot withstand the heavy stone castle. Borui craftsmen used limestone and rammed earth to build a four-meter-high sentry base. The upper part can only be made of wood, and lighter pine must be used. Because pine wood is easy to rot, Borui Kingdom imports a large amount of wood from Suse Kingdom every year for repairing shore guard posts. The purchase cost plus the labor cost and transportation cost, the high cost of Borui people to maintain river bank defense is staggering.

Although blue brick is more brittle, it is much stronger than pine, not to mention it is corrosion-resistant. Even on the damp shore, the blue brick building can be used for at least ten years. This alone saved the York family a lot of money.

"Open the gate." Sylvia walked over and said.

"Open the gate!" The York family trainee Knight gave an order, more than a dozen strong soldiers turned the winch, the iron essence chain made a "zhi zhi quack" sound, and the heavy gate was pulled a little bit. When I got up, with a sound of "wow", the river water poured into the gap in the gate and flowed away along the three-meter-wide channel.

Baita scholar Albert stared at the turbid water spray, muttered: "It doesn't matter if the sand is washed in. With the control of the control gate, hired workers can dredge the canal at any time, and the river will be continuously... I understand...It is precisely because of the control gate that this kind of canal can continue to extend... A control gate was built to the south of the artificial lake, a canal was dug, and the water was led to the black river 7 kilometers away. An inexhaustible artificial river is formed. The irrigated land is not 100,000 mu, but 300,000 mu!"

"Phoenix Baron originally had no stable water source, and it is impossible to have too much arable land now. There are 300,000 acres of fertile land."

"This is a great miracle!"

Father Uli was proud of his face. Bishop Pierot and the scholars sighed. Xi Tuo Master shouted: "Since it is a miracle, how can it be a trifling of 300,000 mu?"

A coolness rose from the tail vertebra, Pierot couldn't help but shivered, and he was shocked by a bold conjecture The ground was numb, and the top of the York family kept smiling, they had been shaken long ago.

"The...aqueduct that runs through the entire Centaur Hills?!"

The young scholars still couldn't believe their conjectures. Tacitus said to Edwin: "Centaur Hills has built hundreds of stream reservoirs. These reservoirs have the same functions as artificial lakes! They are all this..."

"The nodes of the artificial irrigation system!" Edwin said.

"More than 1,000 kilometers of artificial rivers, hundreds of artificial lakes, this...this is simply indescribable! Indescribable" Albert couldn't even find a word to describe this miracle, so he had to keep repeating it. Unspeakable".

After a long time, the scholars finally digested this incredible idea, and finally someone raised a question.

"Master Edwin, I have a problem here!"

"The black river is just a shallow river. If the artificial irrigation system leads the water from the Jinshui River into the black river, it will inevitably lead to river water. Soaring, flooding the river bank, forming a large area of ​​marshland! Isn't it worth the loss?"

"Circular irrigation channel!" Before Edwin could answer, Bishop Pierot lightly spit out a word.

This world is not without artificial rivers. The moat surrounding the castle is also a river dug by hand. Skilled craftsmen can even build canals to introduce river water into towns to meet daily needs. Similarly, the method of digging ditches to divert water to irrigate farmland has existed thousands of years ago. The central part of Gambis Kingdom and the south central region are alluvial plains of the Blinol River, where the land is fertile and suitable for growing crops. In order to reclaim more farmland, the lords on the plain mostly built canals to irrigate the land several kilometers away with water from the Blinol River, but the canals must be connected back to the Blinol River, otherwise the river water would flood large areas of land.

The canal goes around and returns to the main river. People call this canal a ring irrigation canal.

Due to the problem of siltation, most of the annular irrigation canals are only 1.5 meters wide, 70 cm deep, and no more than 20 kilometers long. The longest circular irrigation canal is located in the territory of Suse Kingdom, which is only 17 kilometers.

Circular irrigation canal can meet the needs of irrigation, but it can not play a role in diversion. However, with a restraint gate, it is different.

The black river runs north-south, the streams and reservoirs of Centaur Hills are on the west side of the black river, and there is a very vast land on the east side of the black river. The York family built control gates on the east side of the river, excavated wider and deeper circular irrigation canals and artificial lakes, which not only played a role in diverting water, but also irrigated countless farmland.

This is the full picture of the artificial irrigation system!

"Every canal has a control gate, and a stream reservoir is connected to the black river. Once a certain canal is blocked, it will be closed and dredged immediately. The impact on the entire irrigation system is minimal. The main gate is closed during the rainy season. The stream reservoir has become a cistern again, so there is no need to worry about flooding...What a clever concept, what a great project..."

Master Tacitus sighed and asked with a trembling voice: "old Friend, how much farmland can be cultivated by the artificial irrigation system?"

"Conservative estimate...120 million mu!"

Bishop Pierot felt dizzy. Gambis Kingdom has 210 million acres of farmland, and Centaur Hills is about to develop more than half of the total farmland in the kingdom! You know, although the area of ​​Centaur Hills is large, there are many hills, and the amount of water in the black river is limited. The land that can be cultivated is far from the Blinol Plain. The Gambis royal family occupies the most fertile plain, and they control only 110 million acres of farmland. .

What does farmland mean to the lord?

The output of farmland is indeed not comparable to that of mineral veins, but the minerals will always be mined one day, and the farmland is harvested every year. It is the lord’s greatest wealth! With farmland, the Lord's family has the foundation of continuous inheritance. Many trainee Knights fell into the arms of other families precisely because the family could not give the farm. Fighting for precious land resources has always been the theme of human warfare, both internally and externally!

The artificial irrigation system of the York family can cultivate hundreds of millions of acres of farmland. Can other families copy it?

Bishop Pierot thought about it carefully, and found it very difficult, almost impossible to achieve!

The water source of the York family is drawn from the Jinshui River, precisely because the ant-man army wiped out the murlocs on the riverbank. Other lords want to defeat the murloc? Just look at the Kingdom of Borui to know how difficult this is. The five ruling families of the Borui Kingdom fought the murlocs for 80 years, and they were almost on the verge of collapse before the first port was built. No family has such determination and strength.

Assuming that the lord draws water from other rivers, he will immediately face war. In fact, wars between lords are not uncommon because of water sources.

Even if the lords work together to eliminate the murlocs, who will control the temperance gate? Who is willing to hand over his own destiny to the control of other families? This is almost an unsolvable problem.

If it weren't for this reason, how could no one think of such a simple facility as the control gate? No need to have it!

More than a dozen lords in Centaur Hills are vassal lords of the York family. However, if it were not for Sylvia's prestige, they might not have reached an agreement. No matter what will happen in the future, at least the York family has taken the 1st Step. Just like the Borui people, the 1st Step will go on forever.

The take-off of Centaur Hills is unstoppable!

Bishop Pierot can think of, others can think of, dozens of young scholars have different expressions, some worry, some excitement, some yearning.

Pierot clear comprehension to Sylvia's intention. These scholars come from various kingdoms of mankind. They have the Gambis nobles, the Dodo nobles, the Suse nobles, and the Sasan nobles. The glorious future of Centaur Hills will spread throughout the entire human world through them. Knight and scholar of those small families will flood into Centaur Hills and take refuge in the York family because they have enough farmland!

"Cattle and sheep do not compete for land with people! Raise hundreds of thousands of wild boars! More than 100 million acres of farmland! How many people can this feed....... How many people can this feed?"

p>

Fr Uli flushed with excitement, Pierot suddenly realized that the new agricultural and pastoral system and the water conservancy project are completely integrated! Once the project is completed, Centaur Hills will be able to accommodate one million people. The biggest beneficiaries of this miraculous project are the church and civilians!

"Your Majesty Sylvia, I would like to congratulate you. You conquered the Jinshui River and transformed the Centaur Hills. This is a pioneering work that no one has ever done before! Your great achievements will be remembered by history. , Your wisdom and courage will sing for the epic!"

Master Tacitus solemnly saluted Sylvia, and Sylvia gracefully returned the gift. Tacitus embraced Master Edwin again and praised: "old friend, I also congratulate you. Alya established the vassal system, changed the history of mankind, and you changed the nature, your extraordinary achievements are enough to match the founder of Baita Comparable, your name and deeds will be carved on the wall of the silver tower!"

"haha, my old friend, I did not invent the water conservancy project!" Edwin said with a laugh.

"Ah...that was the creation of the Master? Impossible?!" Tacitus followed Edwin's gaze and saw Viscount Randal who was shooting the murloc, incredibly Said.

"sou" "sou" "sou"

The yew longbow kept crashing, and three murlocs 500 meters away were nailed to the ground by long arrows falling from the sky. Nicole, with a face of happiness and admiration, took the longbow from his lover, took his arm, and walked over.

"Your Excellency Randal, really didn't expect, it turned out to be you..."

Tacitus Master unconsciously used honorifics, Victor waved his hand quickly and said, "My place Can you design such a complicated system? I just provided an idea for Master Edwin. It was Master who designed the control gate and perfected the whole idea."

Master Edwin took a look at Victor with relief. In order to hide Victor, Sylvia once wanted to put water conservancy projects and the new agricultural and pastoral system on his head. However, what the old scholar hates most is cheating, and he reluctantly agreed for Victor's safety. With Victor's current strength and reputation, there is no need to hide it anymore, Edwin insists on letting Victor deserve his name. However, Victor resolutely refused to suffer from fame, Edwin could only compromise in the end, after all, this is indeed his perfection.

"Viscount Randal, how did you think of it?" Master Tacitus calmed down and asked curiously.

Victor hasn’t answered yet, Edwin said excitedly: “Victor saw the leader dig a canal to divert water, and found that there were no murlocs on the banks of the Jinshui River. That’s why he came up with this idea! Old friend, this is. Our victory! Absorbing the wisdom of civilians is the future of the Silver Tower!"

"Master Edwin, you are right. The Lord of Radiance of Supreme guides the wisdom of the people, and we need to discover it. And make good use of it." Bishop Pierot said seriously.

Sylvia slightly nodded, peacefully asked: "Your Excellency Bishop, do you have any ideas?"

Pierot gave a long laugh, and said high-spirited and vigorous: A great career is the honor of my life. I will ask Archbishop Lazarus to act as the bishop of Centaur Hills. I firmly believe that the Pope will also value Centaur Hills’ aspirations!"

Pierot is the Pope’s dísciple, his statement is tantamount to giving up the position of Archbishop, and what follows is that the church is inclined to the resources of Centaur Hills. The lords of the York family all smiled, like a long drought in the rain. Telland Count stepped forward and said: "Your Highness, please name the artificial lake!"

"Rose Lake!" Sylvia beautiful eyes turned around, took Victor's arm, and said: "black river It was renamed Yinyue River, and Black Castle Town was renamed Golden Water City!"

Master Edwin said with a smile: "Okay! Qiangwei Lake, Yinyue River, and Golden Water City deserve their name! "
