The night is getting darker, the camp is solemn, the wind in the tent is warm, and the incense burner smokes. The bonfire danced in the big tent, reflecting a figure written by Fuan, which coincided with the moon shadow on the zenith.

Xiulot sat in front of the table, sometimes thinking for a long time, sometimes writing quickly. A detailed map of the kingdom was spread out on his desk, with black towns up and down, and blue rivers rushing north and south. The young king dipped in the expensive red paint, and with his strokes, the blue and black were connected together with the shortest red line!

"Roads in the kingdom are divided into three levels. The first level is village-level dirt roads. The vegetation on the road surface is cleared, the high and convex places are dug and leveled, and the low and concave places are filled with soil to make it easier for pedestrians to go back and forth."

After writing this, Shulot paused slightly. The current roads in the kingdom are basically such dirt roads, which have continued from the era of the Tarasco Kingdom. This kind of dirt road is "a road formed when many people walk on it." In the newly reclaimed Apa County in the south, there is no such road yet.

"The second level is the county-level triadic soil road. The triadic soil road is based on clay and loam, bonded with slaked lime, and then filled with natural sand. The Sanhe dirt road must be compacted by manpower and maintained. The rainy and rivery area with lush vegetation , it is necessary to use cinder, slag, and gravel as the base layer, and fill it with natural sand dug from the sea to prevent water and plants.”

Shulot looked at the map and pondered for a while. He asked the leader of the samurai who transported grain and grass, and carefully investigated the situation of the logistics road. According to the current conditions, the Sanhe soil road should be the most suitable balance between the kingdom's productivity and material transportation, and it will be the focus of the next construction. And the criteria for judging the passability of Sanhe soil roads are also very simple.

"...The road surface needs to be sufficiently smooth and firm, and the standard for passing judgment is a wheelbarrow that can quickly pass through the kingdom's transportation!"

In the kingdom's logistics, a large number of metal-reinforced wheelbarrows have been used. The wheels are covered with vulcanized rubber, which greatly increases the service life, and only needs to repair the bearings once a month or two. However, this means of transport is still an expensive military vehicle. The cost of wheels and bearings is extremely high, and the production of rubber is very limited. Ordinary merchants and people in the kingdom can't afford it at all.

"Class III roads are kingdom-level stone roads. Large and small stones are used as the base material, **** and natural sand are used as fillers, and then cemented with pozzolan cement or asphalt, and then compacted by the people dragging stone rollers. This level You don’t have to worry about rainwater or the root system of plants anymore. Asphalt is toxic to kill plants, while pozzolanic cement is stronger in water bubbles. The standard for qualifying a third-grade stone road is to be able to Horse-drawn carts and ox carts with heavy loads!"

Xiulot imagined the scene of the stone road in Rome, with a little smile on his face. He has already received a letter from Koskaci, the director of Kingdom Construction. The other party reported excitedly that they had discovered the "cement" in the divine guidance. The cement poured into the wall can gradually harden, and finally it is like a big stone, which is difficult to break with the blade of an axe!

"Well, according to Koskaci's description, the volcanic ash cement takes a long time to harden, and it needs to be constantly added with water...somewhat strange."

Thinking of this, Shulot scratched his head. He had only heard the name of volcanic ash cement, and as for the specific principle, he naturally didn't know it. He just put forward the direction and requirements, and the specific practice naturally needs to be explored by the directors, bureau chiefs, master craftsmen and senior craftsmen in the Divine Enlightenment Institute.

"However, Koskachi dare not lie to me. The volcanic ash cement must have been researched. And the craftsman Charcoal who first tested the cement will also be rewarded! ...Promoted as a master craftsman and awarded to the priest of divine enlightenment I will give you another two hundred acres of land, twenty servants, and two hundred catties of gold to inspire craftsmen everywhere!"

After a moment of pondering, Xiulot made a decision. The kingdom's rear is stable, manpower is sufficient, and the number of craftsmen has also grown explosively. Various projects are about to start, and Qianjin Shigu is at this very moment!

"Of course, the volcanic ash has to be transported from the Colima Mountains, which is not so convenient. There are many volcanoes in the Alliance and the Kingdom, so this mountain bird has to take his apprentice to various volcanoes and the foot of the sacred mountain to find more raw materials for volcanic ash cement! "

Craftsmen who make contributions and invent and improve can get generous rewards. They also need to take apprentices and teach relevant know-how. They have the right to choose apprentices, but they are absolutely not allowed to cherish themselves. In fact, the kingdom gave them generous social status and treatment, and they didn't need to use their possessions to make a living.

"Huh! Using volcanic ash cement to build roads is still too extravagant. The output of this cement is limited, and its waterproof performance is excellent. It should be put into the construction of reservoirs and dams first. In the south of the kingdom, the water system is criss-crossed, the lakes are connected, and the rainy season is too abundant. , and the reservoirs and dams for flood storage are most needed!"

Thinking of this, Shulot dropped his quill and drew red circles near several lakes in the kingdom. That is the projected location of the reservoir and embankment. Afterwards, he picked up the map and carefully examined the black-spotted towns, blue-lined rivers, red-lined roads, blue-circled lakes, and red-circled reservoirs beside the lakes... All the construction plans were vividly written on the paper !

All in all, the grand plan for building the kingdom this time is to use the second-level county roads of the Sanhe Dirt Road to connect the big cities and important towns in each county, and the rivers and rivers from the north to the south. Next, the north and south water systems need to be dredged, and the reefs in the river must be cleared. Finally, small reservoirs and dams for flood control have to be built around large lakes to regulate rainfall during the rainy season.

In addition, villages all over the country have received the long-term task of repairing canals. Every year during the slack season, the villagers have to continue to perform various labors under the leadership of the village priest. And the counties should also provide enough tools to subsidize labor rations.

As for the third-level stone road, digging canals... such an expensive project, Xiulot is just thinking about it in his dreams, and he will never carry it out now.

"Building dirt roads in Sanhe, clearing river reefs, building reservoir dams, repairing local canals... These are the four priorities of the grand plan!"

Writing this, Xiulot laughed at himself. Compared with Qin Shihuang's Chidao, Han Wudi's Great Wall, and Sui Yangdi's Grand Canal, such a large-scale project is probably only a fraction of the amount of work. However, such a project is an unprecedented feat for the Kingdom of the Lake, and even the entire Central American world!

And without the popularization of bronze tools and the production of iron tools in the Kingdom, the cost of building roads and dams would be unacceptable to all parts of the world.

"The first priority is to build the county road of Sanhe Dirt Road, connecting the water system and the town!"

Shulot stretched out his finger and stroked the first red line on the map. The starting point of the red line is the Hekou Fortress in Hekou County in the north, and the end point is Qincongcancheng, the capital of the king. The construction length of this second-level county road is about 160 to 70 miles. The road goes south first, connects Mintun villages along the route, then connects with Huayamo Fortress, and finally turns west, connecting to Qincongcan City.

"The first county road is Leman River - Estuary Fortress - Huayamo Fortress - Qincongcan City. The entire northern part of the kingdom is relatively flat and there are many first-level dirt roads. Only this second-level county road is needed to connect the capital city with the city. The water system of the Leman River is more effectively connected together. And the construction of this county road is also based on the dirt road of the Kingdom of Tarasco!..."

Xiulot pondered over the details of this road, and took a pen to mark possible construction difficulties.

"The terrain near Huayamo Fortress is relatively high, so it should be a little difficult, but the overall difficulty of the road is not great."

The first county road has a total length of 170 miles. The land route goes from north to south, and the altitude gradually increases until it reaches the highest altitude near Huayamo Fortress. Then, the road continues to turn southwest, with a slight decrease in elevation, until Khin Trong Chancheng. The altitude of the royal capital Qincongcan is obviously higher than that of the Hekou Fortress. The capital Qincongcan and the Huayamo fortress were originally the city-states that survived the great flood in the last era, and they were both built on the high points of the lake area.

In fact, the altitude of Chin Cong Cancheng is about 2,000 meters, that of Huayamo Fortress is 2,400 meters, and that of Hekou Fortress is 1,800 meters. In the 170 miles of this road, it first rises 600 meters and then falls 200 meters. This kind of undulating terrain is really gentle compared with the altitude difference of thousands of meters in the two southern counties. And this road in later generations is Mexico's Highway 43 to Highway 15.

"Starting from the second county road, it all leads to the south. The second county road belongs to the east line of the southern road and is divided into two sections. The first section of the east line starts from the city of Patzcuaro and walks for one One hundred and fifty miles, arrived at the small town of Alto."

The small town of Alto was the place where Medina assassinated the southern aristocrats at the Shulot Conference a few years ago, and it was also a commercial road node leading to the south. The reason why we started from Patzcuaro is because there is water transport from Patzcuaro Lake between Chin Cong Can City and Patzcuaro City. The efficiency of water transportation is much higher than that of land transportation, even if it is a third-level stone road, it is difficult to compare.

At the beginning of the planning, Schlott minimized the amount of work for the "big plan", laying out the main trunks of several arteries first.

"The first section of the eastern line is 150 miles long. From south to north, it also rises first and then lowers. The closer you get to Alto City, the faster the terrain lowers, and it begins to appear steep."

The first section of the second county road is a land road with a total length of 150 miles. This section of the county road is the No. 120 Highway for later generations. Patzcuaro City is 2,200 meters above sea level, slightly higher than Chin Cong Can City. The altitude of the small town of Alto is only 1,500 meters, and the high point between the two ends is a mountain village at 2,400 meters. Therefore, the front half is flat and easy to repair, while the second half of the eighty-mile road will suddenly drop by 900 meters, and it will be a lot of trouble to build.

"Fortunately, on the second section of the Eastern Route, starting from the small town of Alto, there is a navigable river, which is called the "Running River" locally. The rushing river is extremely fast, going south from Alto, turning southwest, passing through LaPena in the mountains, traveling 160 miles, and merging into the great southern lake, Lake Atoyak, in Crow Town. This 160-mile waterway has fast-flowing water, large drop, reefs, tidal flats and small waterfalls. However, the kingdom’s canoes can pass through, and merchants come and go through this waterway, which is far more efficient than the previous section...”

After writing this, Shulot frowned slightly. This section of waterway needs to be dredged to allow long ships to pass and improve the efficiency of water transportation. The folks not only need to clean up the reefs in the river, but also smooth the small waterfalls in the middle of the river, or dig a curved river to go around. And these river projects in the mountains rely on manpower alone, and I don't know how many lives will be consumed. The best way is to use granulated black powder to explode and then dig.

"We can start with a simple one and fix it a little bit. At present, although the boat is risky, it can still pass. As for the name of this "Running River", it has to be changed! Well, it starts from Alto and ends with the former Crow Town of the Seatley family, flowing into the vast Lake Ato. To be concise, let's call it... Aoya River! "

The second section of the second county road is the Aoya River waterway, with a total length of 160 miles. Alto City is 1,500 meters above sea level, while Crow Town at the end is only 200 meters above sea level. In one hundred and sixty miles, the drop was 1,300 meters, an average of eight meters per mile! With such a waterway with a difference in altitude, it doesn't even take a day to go down the river from north to south. But from south to north, it is much more difficult, and someone needs to pull the fiber in the dangerous place. Thirty or forty miles a day, it is estimated that it will take five or six days to complete the trip.

The Patzcuaro Lake area in the hinterland of the kingdom has the highest terrain. The Chapala Lake District in the west and the Hekou County in the north are all lower. As for the two southern counties, the terrain is the lowest. Being condescending, even the situation of mountains and rivers also has the advantage of marching and attacking! The former kings of Tarasco should have such considerations in establishing their capital in the Lake Patzcuaro area.

"The third county road is also divided into two sections. The first section is divided into two sections. It starts from the commercial city of Invachio, goes westward for sixty miles, connects to Blackstone City in the Qinganbat mining area, and then goes westward for sixty miles. , connecting the Flower and Fruit City in the mountains. The difficulty in building the road is between the Black Rock City and the Flower and Fruit City.”

The first section of the third county road has a total length of 120 miles. From northeast to southwest, there are three important towns in sequence, all sixty miles apart. This county road is Highway No. 14 in later generations. It has beautiful scenery and is difficult to drive.

The important commercial town of Invachio, referred to as the Mall for short, is located on the shore of Lake Patzcuaro, connected to the capital by water, and is also about 2,100 meters above sea level. The altitude of the Qinganbat mining area is about 2,000 meters. UU Reading www.uukanshu.com From the shopping mall to the Blackstone City in the mining area, you have to walk through several hills of one or two hundred meters in zigzags. Although there are detours, the construction is not difficult. Moreover, the mining area can provide road construction materials nearby, reducing a lot of transportation engineering. In fact, in order to transport the copper and coal out of the mining area, this section of the road has been roughly repaired once, and it can pass a wheelbarrow. All that needs to be done is to continue strengthening and repairing.

The altitude of Huaguo City is about 1700 meters. From Black Rock City to Huaguo City, the Thirty-Li Road is lowered by 300 meters, and there are several larger hills. The difficulty of building this section will be higher. But in general, it is easy to build roads near the mining area.

"And from Huaguo City to the south, Goulian Apa Plain is the real difficulty!"

Xiulot straightened his spine and cheered up. He stretched out his hand to connect the north and the south, and across the vast south, a blue waterway and a red line of land came into view at the same time!
