The night was getting dark, and the light of the fire in the tent was also a little dim. The head of the guard, Eckart, stood aside, looked at His Highness who was thinking in front of the table, called a guard, and gave a few instructions in a low voice. After a while, someone came with a birch candle.

The so-called birch candle is a candle made of birch bark. Of course, other flammable bark can also be used, but it is more troublesome than birch bark, and most of them need to be steamed first. This kind of candle belongs to the ancient candle in the Tian Dynasty, and it appeared in the Han and Tang Dynasties, and it was not until the Song Dynasty that it entered the homes of ordinary people. For the nobles of the alliance, they also have an equally ancient lighting method, splitting pine wood into thin strips and lighting them up, which is the "pine light" of the Chinese dynasty.

Eckart carefully lit the birch candle, placed it in the corner of His Royal Highness's table, and then stepped back to stand. Xiulot raised his head, glanced at the candlelight, and nodded slightly. Then, he picked up the quill, dipped it in blue ink, and wrote on the yellow paper.

"From Huaguo City to the south, there are two roads, east and west, which can lead to the south. The east route is a steep waterway, along the Yuan River, 140 miles down the river, and you will reach the mouth of the Yuan River. From here, go south for another 10 miles , is the western part of Lake Atoyak!"

The third county road, the east line of the second section, is the waterway from Huaguocheng-Yuanhekou-Atoyak Lake. Among them, Huaguo City is 1,700 meters above sea level, the height of Yuanhe Estuary is only 240 meters, and the water level of Atoyak Lake is between 160-190 meters. The 140-mile waterway has a drop of more than 1,400 meters, and the danger can be imagined. The water flow of this river is extremely fast, and the water is extremely turbulent, so it is called "the river leading to the abyss" by the locals, Yuanhe!

"When I marched south, I sent the Third Legion to go south. The Imperial Guards went down the Aoya River, and Ezpan's Second Long Spears went down the Deep River! Going down the river, the speed of the small boat is extremely fast. But collisions with rocks and cliffs, ship crashes and fatal accidents also happen from time to time..."

"This precipitous river requires a lot of manpower to dredge, break through or bypass the small waterfalls in various mountains. And along the river, a first-class dirt road should be built to facilitate the back and forth pulling of fibers."

Xiulot thought about this, concentrating on it. He is well aware of the importance of the Abyss River waterway to the kingdom's southern rule.

The carrying capacity of the Yuanhe River is huge, and it is the most convenient road to connect Gyeonggi and the southern counties. Although the passage of this river is dangerous, it is still the main channel for the kingdom's bulk goods and trade between the north and the south.

The coal in the Black Rock City mining area is transferred from Huaguo City, through the raging Yuan River, all the way to Atoyak Lake. Then go downstream, along the tail end of the Tulsas River, to the Black Rock Mountain Iron Mine on the seashore. This river and lake are smooth, flowing from the north to the south, and can carry heavy cargo for more than 100 miles a day, which cannot be replaced by any land road between mountains!

Caravans shuttle, and the exchanges are prosperous. In the middle of this waterway, there are several large villages, which earn the passing fees of business travelers and provide manpower for pulling fibers. Traveling along the river requires pulling fibers not only upstream. And downstream, if the estuary is too steep, the fiber should be pulled in the opposite direction to slow down the speed of the boat.

The village closest to Lake Atoyak is at the mouth of the Yuan River. Between the Yuanhe Estuary and Ato Lake, there is a barren ten-mile tidal flat, which is usually a river channel. When the heavy rain in summer causes the water level to rise, it will flood into a lake.

"When it rains in summer, the water level of Lake Atoyak will skyrocket. The reason is that not only the Deep River and the Aoya River in the north flow into this place, but also the Talesas River in the east and the Apa River in the west. It also flows into here. And the Apa water system, through the Chatau River, connects with the Chapala Lake area, leading the upstream lake water to the south... Reservoirs must be built in the upstream rivers!"

Shulot pondered for a moment, then drew a few red circles on the west side of Lake Atoyak for the construction of the reservoir.

Atoyak Lake, the real "big water lake". When this great lake was at its peak, it could stretch one hundred and fifty miles from east to west! Half of the Lake Chapala area, the entire southern part of the kingdom, and the entire lower reaches of the Tulsas River, more than 200,000 square kilometers of precipitation, will flow into this place. Then, the vast precipitation gathered in a raging river, three hundred miles south, and rushed into the Pacific Ocean around Trouttown, forming a fertile flood plain at the mouth.

"The two counties of Zicao and Apa reclaimed by the immigrants of the Kingdom are both in the upper reaches of Lake Ato, on the north and west sides of the Great Lake. In large settlements such as Apa City, Zicao City, and Taotu Town, there must be Along the rivers and lakes, build a series of reservoir dams to regulate the amount of water in the rainy season and prevent flooding!"

Xiulot kept writing, and drew a few red circles. The reservoirs to be built here are not the "four major reservoirs" with a storage capacity of one billion cubic meters when the Huaihe River was governed in later generations, but small rural reservoirs with tens of thousands and a storage capacity of 100,000 cubic meters.

In the grand plan, the entire water conservancy construction process is similar to that during the Han and Tang Dynasties. The development of the Bashu Plain will last for a long time, and small water conservancy projects will be continuously added. The main amount of work is to excavate rivers and lakes, build ponds around dams, and build dikes. The ultimate goal is to realize "Floods and droughts follow people and don't know hunger"!

"This is a long project that will take decades. However, I always start planning now, and I have enough patience and time!"

Shulot thought about the prosperity of Shu in the Celestial Dynasty, and had the same hope for the two counties in the south of the kingdom. After a while, his eyes turned to the seashore further south.

In the middle of Lake Ato to the mouth of Talsas, the mighty Talsas River flows through a section of towering cliffs. The terrain here is tortuous and towering, which is a natural large-scale reservoir node.

Xiulot stared at this position, and slowly picked up the pen. He first drew a red circle, then filled the circle solidly, and softly read a name that no one could understand.

"InfiernilloDa Hell Dam, one of the largest dams in the world in later generations. It has a storage capacity of 10 billion cubic meters and a power generation capacity of more than 1,000 megawatts!... At the end of the Talsas River, if such abundant water power can be used Get up, what a majestic power will be produced!"

The king's finger gradually moved south, and finally settled on the location of the Black Rock Mountain Iron Mine. He has already issued orders and rewards for the research of hydraulic machinery to many priests and craftsmen in the Divine Revelation Institute! As long as he can make qualified hydraulic machinery, he will generously bestow titles, bounties, fields, and serfs!

"Keel water wheel... bobbin car... water reel... water mill... air blower and water row... hydraulic forging machine..."

Xiulot opened the "Book of Divine Revelation" that he carried with him, looked at the name of the hydraulic machinery written by himself on it, and looked yearning.

In this era, based on mature metallurgical technology, hydraulic machinery has gradually become popular in Europe, especially hydraulic forging machines that can forge armor. If we can bring back a few European blacksmiths, and then bring back a few mechanical scholars, and limit the kingdom's material and technical bottlenecks, we will make a dramatic breakthrough! And at that time, the end of this turbulent river will become the power source of the kingdom's prosperity!

"There are still three years...the prelude to the great era, three years left!..."

After a long time, Shulot sighed faintly. He shook his head, moved his fingers patiently, and then landed on the west route from Huaguo City to the south. This is a red land route, and it is also the western route that Hei Lang led the dog-born army to the south to conquer the city of Apa.

"From Huaguo City, walk a 150-mile mountain road to the foot of Apa City. This mountain road is not narrow and can pass through large armies, but the mountain is steep and undulating. And this 150-mile road is also the last one that needs to be built. County road!"

The altitude of Apa City is about 350 meters. It is higher than Lake Ato and is located in the upper west. Huaguo City is 1700 meters above sea level. This 150-mile mountain road has a drop between 1300-1400 meters at both ends. However, the middle section of this county road will pass by the foot of the towering Tansitaro Volcano (Tataro), and the highest point is about 2,300 meters, which is quite difficult.

"Tancitaro Volcano, sulfur mines and avocado...maybe, and volcanic ash."

Xiulot took the quill and tapped a red dot heavily on the position of Tansitaro Volcano. This volcano is the highest peak in the Mikencho area, with an altitude of nearly 4,000 meters. The overall terrain is very towering and the mineral resources are relatively rich.

The county road of the kingdom has to go through the foot of the volcano, and there is an undeniable main reason. Around this volcano is the kingdom's sulfur production area, which provides the raw materials for the kingdom's gunpowder. Another less important reason is that the land around the volcano is extremely fertile and there are many avocado trees. Several nearby mountain villages are famous avocado producing areas.

As for the fertile land at the foot of Mount Tansitaro, it also means the presence of volcanic ash. If the volcanic ash needed for cement can be found, the construction standards of this section of county road can be raised nearby. In the easily damaged road sections, replace them with stronger and more waterproof cement composite soil roads.

"Once this one-hundred-and-fifty-mile west-line county road is completed, the unicycle that can be used for transportation, and the connection between Gyeonggi and Apa City will suddenly become closer! And the most important significance of this county road is to strengthen the Kingdom Central, Regarding the rule of the Apa Plain. After all, there are tens of thousands of Tekos immigrants and more than 100,000 Tlaxcala immigrants. This is a total of more than 200,000 people, almost all of whom are subjugated tribes. We must pay close attention to assimilation and Condensate!"

Shulot stared at the vast Apa Plain, thinking about it. Cultivate fertile fields, build villages, install flag teams...Ezpan has done a good job in Apa County. His loyalty has passed many tests, and Shulot is also very relieved.

However, Shulot knew that this kind of loyalty only belonged to the king and Ezpan and his subjects, not to the kingdom. Once Ezpan died, or Xiulot had an accident, there would definitely be a rebellion in Apa County! In order to increase the control of the kingdom, the construction of this secondary county road is imminent. And large-scale missionary missions by priests, cultural assimilation, and forced intermarriage also need to be strictly implemented!

"The first three county roads in the grand plan are all connecting the north and the south. The last Apa River System is going to run through the east and west!"

Shulot's eyes stayed in Apa County, and fell on the criss-crossing Apa water system. The reason why "water system" is used to describe it is because the Apa Plain is flat and densely covered with water networks. For rivers with sufficient flow alone, there are Apa, Hetao, Kan, Bo...

These rivers meander and intersect with each other, flowing through a radius of 150 miles, connecting settlements such as Apa City, Taotu Town, Kanhe Village, Bohe Village, etc., forming a waterway transportation network with convenient communication. Then, from the city of Apa, the Apa River travels eastward for another hundred miles and flows into the Great Lake Ato.

"The upper reaches of the Apa water system are Olive Lake in Taotu Town and Peli Lake in Bohe Village in the upper reaches of the west, and the vast Ato Lake in the lower reaches of the east. From west to east, it is about 220 miles long, and the terrain is quite flat. , the drop is only over a hundred meters.”

"The big plan's requirements for the treatment of the Apa water system are to be able to transport long ships and prevent floods during the rainy season! After the autumn harvest this year, the water levels in all rivers will drop. All flag teams and villages in Apa County will To serve in the army. Mobilize tens of thousands of men to dredge the river, dig river mud, and build small reservoirs and dams at the same time! And the river bottom mud dug out can be used to fertilize the fields..."

Shulot stared at the two ends of the Apa water system, thought for a long time, and carefully wrote down the requirements for Ezpan. This Apa system is actually a continuation of the lower western branch of the Tulsas River. In other words, the Talsas River, this golden waterway, spreads from east to west for two or three thousand miles!

"No, it's more than that long!"

The king pondered for a while, and swiped the tip of the pen upwards from the clay town, drawing a zigzag south line to the Chapala Lake area.

"In addition to the three north-south county roads, an east-west water system, and another waterway of more than 300 miles, the Chatao River!"

Chatao River was named by Shulot himself. As the name suggests, it is the long river from Lake Chapala to the clay town of Apa Plain. Well, the name of the king is so concise and straightforward!

The Chatao River is not narrow enough to pass large armies. This long river flows down from the southern end of Lake Chapala, two hundred miles southeast, and arrives at Snakebone Village in the northwest of Apa County. Then, turn southwest again, pass through Bohe Village, the tributary connects to Peli Lake, and the mainstream flows out for a hundred miles, connecting to Olive Lake outside Taotu Town.

"Therefore, Lake Chapala is the upper reaches of the Apa water system. Only by capturing the Lake Chapala area can a solid barrier be established for the developed Apa Plain."

Shulot dropped the quill and drew a red circle heavily on Lake Chapala. The Feather Prince's strength is weakening day by day, and he has no spare power to go deep into the Apa Plain to plunder. But if the kingdom wants to have complete mountains and rivers, it must capture the Chapala Lake area to form a complete waterway.

So far, the north is the Leman River -> Estuary City -> Chapala Lake District, the south is the Tarsas River -> Zicao City -> Apa City -> Apa Water System, and the middle is the Estuary City -> Patzqua Luohu District -> Three southward passages, and the west is Chapala Lake District -> Chatao River -> Apa Plain -> Taotu Town -> Apa Water System.

Four waterways and main roads form an irregular quadrilateral. Five hundred miles from north to south and five hundred miles from east to west~lightnovelpub.net~about 60,000 square kilometers. And with such a complete road network and water network, the area of ​​60,000 square kilometers is the center of the kingdom, the hinterland that can be directly controlled! Based on this, and then extending in all directions along the waterway, the territory that can be controlled will be several times this!

Thinking of this, Shulot's eyes sparkled, his chest was surging, full of pride to conquer the world and conquer the world!

"The kingdom's first big plan is to mobilize more than 100,000 laborers and more than 10,000 samurai to start construction in all counties after the autumn harvest! The most important part of it is to build four sections of secondary county roads totaling 600 miles , to dredge three sections of rivers totaling six to seven hundred miles, and completely run through the north and south!"

"When the preliminary construction of the county road is completed, the will of the king's capital can pass through the south. And the next step is to attack the Chapala Lake area. After the capture of the Chapala Lake area, it is the second big plan. The road network of dominion is extended again!"
