"Oh? So the tribes on the island in the middle of the lake have almost moved away?" Luo Chong asked while taking a sip of tea from a blue and white porcelain tea bowl.
"Well, almost, the remaining three tribes have less than 2,000 people in total." Yun Zhi calculated in his mind and reported to Luo Chong.
"Where did Youye go? Why didn't I see him? How was his terrain reconnaissance?" Luo Chong asked again.
"Oh, this, he took the fleet out again today, but he has drawn a lot of maps recently, but I can't understand them. Do you want to see them, Chief?"
"Well? There are maps, then, bring them all to me." Luo Chong, who was originally drinking tea in a depressed mood, immediately became interested when he heard that there were maps. In this way, he could choose a site for the coking plant in advance.
Yun Zhi also quickly brought a pile of maps, which were all drawn on thicker custom paper. When surveying, they were first outlined with a pencil, and after coming back and sorting, they were drawn into a large map with a brush. Yes, the stack of maps in Luo Chong's hand were all scattered maps.
However, as the only team in the Han tribe who received Luo Chong's true surveying and mapping skills, Youye's team really drew very carefully. They did not draw blindly, but carried flag poles, tape measures and compasses to draw.
Although the maps were relatively scattered, each one was marked with directions and scale conversions, and all were marked with square dotted grids according to the method Luo Chong taught at the beginning, representing the longitude and latitude of the map. The maps drawn in this way were also more standard. As long as the directions of several important landmarks and the distances to the grid edges were measured, the shape of the terrain could be accurately drawn, and the actual error would not exceed one meter.
Luo Chong spread the maps on the table one by one according to the directions and numbers, gradually splicing them into a huge map, and then called Yun Zhi.
"Go get a ruler and a pencil, and some blank surveying paper. I need them."
"Oh, OK."
Yun Zhi agreed, and quickly went to get what Luo Chong wanted, and then stood beside Luo Chong to watch and study. He only realized now that these messy maps had rules and order, and they could actually be put together. It was really amazing.
After Luo Chong put the map together, he took out a stack of text annotations, which also showed that Youye's work was meticulous.
The annotations also had numbers on them, corresponding to the maps of each area, and then explained some places on the map marked with special symbols.
For example, one of the maps was marked with East 130 to East 150, North 40 to North 50, which means that this is a map with the dock of Weishan County as the starting point, 130 kilometers to 150 kilometers to the east, and 40 kilometers to 50 kilometers to the north. This is a rectangular area with a length of 20 kilometers from east to west and a width of 10 kilometers from north to south.
The map shows a half-land, half-lake terrain, and it is divided into many small grids by dotted lines. The small grids are also numbered. Some special places are written with "Note 1, Note 2". At this time, you have to look up the text annotations, find the corresponding area, and then look at the corresponding notes above.
For example, the notes on this map read: Note 1, the island is large, approximately long and oval, the terrain is relatively flat, the soil is sticky, there are few stones, no bamboo, many reeds, sparse short trees, large areas of abandoned farmland, an abandoned thatched house residence, no ferocious beasts and snakes, many large birds, hiding in the reeds.
The map composed of lines, plus such a text annotation, even if you have never been there, people who look at the map can imagine the real landscape with this.
It was an island in the middle of the lake left by a tribe that had moved away. The original farmland and residence on it had been abandoned. It was normal that there were no ferocious beasts. After all, people lived there before, and the beasts had been killed long ago.
The shape of the island is a long oval with a flat terrain. It is all clay, not many stones, no bamboo, and few trees. There are sparse shrubs and many reed marshes, which hide many large water birds. There
is also Note 2, which says that there are many swamps in the northeast of the island. The water is less than half a meter shallow, and there are many small-leafed vines and aquatic plants, which cover the water surface. Large and small boats cannot pass through. They can only use sickles to clear the way and use bamboo rafts to move forward. The area is very large. There are many prawns and blue crabs in the water, which are delicious and edible. However, it is recommended not to enter this area easily, as people are easily trapped by water plants and drowned in the mud.
The second note describes in detail the waters in the northeast of the island. They are all swamps, with a large area and shallow water levels. Large and small boats cannot pass through. They can only use bamboo rafts to float forward. In addition, the water surface is covered with a kind of aquatic plants with small leaves and long vines, which can easily trap bamboo rafts. A sickle is needed to clear the way. It is recommended that people do not enter easily, as they are easily trapped in the swamp.
However, there are also many shrimps with big claws and crabs with green shells in this shallow water. They taste very good and can be eaten.
This map with all the scales and directions marked, coupled with detailed text annotations, is even better than the current 3D real-life map. The text, lines and rulers make it feel like you are actually there. You can see the whole picture of what is drawn on the map at a glance.
Luo Chong picked up something ready-made here. In fact, it was very hard for Youye and his team to draw such a map. It required a group of people to carry flags and poles, pull tape measures, and hold compasses to measure one kilometer at a time.
Of course, not all places need to do this. In some places, you only need to measure the distance and water depth. It doesn't need to be so troublesome. For example, if the area within a radius of five kilometers is all lake water and there is nothing on it, then what can you measure? Just measure the distance, and then leave this area blank on the map, indicating that it is all water, quite deep, and can run large ships. There are many fish and wild ducks. There is really nothing else to remember.
Just like mapping grassland terrain, one kilometer is all grass, a flat land, and then another kilometer, it is still all grass, a flat land. What can you remember? Just mark it with a grid and indicate that there is nothing.
Therefore, when encountering such empty terrain, the mapping speed can be faster. The more complex the terrain, the slower the mapping.
Luo Chong looked at the map one by one according to the annotations, and then took a pencil and wrote down the large ship channels he found on another blank paper. After all, the ships carrying coal must be very heavy and have a high draft depth requirement, so some deep-water channels must be planned for ships.
Then, along these deep-water channels, look for the lake islands that are closer, and see if there are any swamps or other terrains around these lake islands to discharge pollutants. Finally, look at the size of the islands that meet these conditions, what resources are there on them, whether the land is flat, what kind of soil it is, what the surrounding hydrological conditions are, whether there is a risk of flooding due to rising water levels, and whether heavy coal refineries can be built on them.
In this way, using the elimination method to screen one by one, Luo Chong really found five suitable islands, of which three have an area of more than 20 square kilometers, that is, an island that is five kilometers long and four kilometers wide. The area is definitely enough. According to the records in the annotations, there were originally large tribes on these islands, but now they have all been abducted to Weishan County by Yun Zhi.
The remaining two also have an area of more than 13 square kilometers, and the smallest one is seven square kilometers.
These five islands are close to deep-water channels, so docks can be built directly to allow large sailboats to dock. In addition, there are shallow swamps in other directions, or simply swamps without water. Such places are very suitable for discharging pollutants, and there is no need to worry about polluting the water quality. The heavy metal emissions can be directly absorbed by the swamp. Although they cannot be degraded, they cannot flow out. They can only sink deeper and deeper, or be absorbed by swamp plants.
After selecting these five islands, Luo Chong began to assign uses to them. First, the largest island is needed to process coal mines, wash coal, coke, and synthesize calcium carbide. These are all business contents. The products produced are coke, tar, calcium carbide, and finished coal mines. Of course, it is also possible to use the remaining coal slag to make coal balls or honeycomb coal, but it is estimated that not many people will buy them, because the cost of production and transportation is definitely not as cheap as cutting firewood nearby.
The second is the copper, lead, tin, and silver metallurgical workshops, as well as the Imperial Mint. These things should be placed on a larger island, where metal raw materials are smelted on one side and the finished products are sent directly to the other side to be stamped into coins.
This thing can be built now. Even if you can't start smelting metals immediately, it's still possible to stamp currency there. The first is safety, and the second is that the place is relatively large, so you can do more and expand the production capacity of the mint. How
big is an island with an area of more than 20 square kilometers? It is about the same as 2,860 standard football fields, which is about the same size as a small county town with a population of hundreds of thousands in modern times.
Such an area is enough to build an industrial zone. Not only can many large factories be built, but also dedicated residential areas for workers can be divided, and some sports and entertainment facilities can also be built, such as Diaoyutai. After all, it's a pity not to use it. There are also football fields, chess and cards and other leisure games.
People who work in such places are basically isolated from the world. There is water all around, and they can't go out at ordinary times. If they don't take some entertainment measures, it's easy to get suffocated.
Moreover, after the development of the industrial zone is on the right track, it is also possible to build a staff family area and bring the workers' wives and children to live together. However, if this is really the case, a special school for the children of workers needs to be established on the island, which is equivalent to an independent small social system, but it is still under the leadership of the Han tribe. After all, their raw materials and products still need to be sent in and out from outside.
The third island with an area of more than 20 square kilometers cannot be used up by building a single workshop. The place is too big, so Luo Chong plans to build a high-tech industrial park on it, which will bring together a variety of emerging industries to form a large park.
The main production of glass in this park is glass. After all, there are coal mines, alkali mines, and silica raw materials such as crystal and sand. Luo Chong can also gather other catalysts, so it is completely possible to produce ordinary glass, the kind of ordinary glass that ordinary people can afford, and even glass can be used to make utensils in large quantities in the future, such as wine bottles.
In addition to glass, a large hardware machinery factory will be built here to focus on the research and development of various metal tools, machines, and the production of metal parts.
For example, the metal parts needed for oil lamps and gas lamps can be made directly by the hardware machinery factory, and then directly installed with the lampshade produced by the glass factory next door, and the finished product can be sold directly.
In addition, a rubber factory will be built here, mainly to develop the Eucommia ulmoides forest north of Fumaguan, extract Eucommia ulmoides gum from the Eucommia ulmoides trees, and use it to develop rubber products, such as rubber soles, rubber gloves, rubber rain boots, solid rubber tires, hollow pneumatic tires, hollow pneumatic balls, acetylene rubber air hoses, valve cores, shock-absorbing rubber pads, sealing rubber pads, and other rubber-related things.
The glass factory, machinery factory, and rubber factory, these three factories help each other, and it is really possible to make anything. As long as these can be built, even if Luo Chong is asked to make a pedal bicycle, he will have the confidence.
Of course, these things can't be thought of within five years at least, because just building these factories alone is not something that can be done in one or two years, not to mention the time for research and development. In the end, there will be formal output, which will definitely take a process.
As for Eucommia rubber, Luo Chong also has some knowledge about it. He can't be considered as a researcher because he knows how to extract it.
This is a Chinese specialty rubber tree. More than 90% of the world's Eucommia is in China, so even if you don't know the natural rubber tree, you have to know the Eucommia tree, not to mention that this thing was a famous Chinese medicine in ancient times.
Unlike the rubber tree, Eucommia gum does not have milky white glue flowing out, but exists in the bark, leaves, roots, branches, flowers, and fruits in a solid form. As long as you break the above things, you can see the silk threads formed like pulling chewing gum. Those white silks are Eucommia gum.
When extracting Eucommia gum, you only need to dry these plant raw materials, crush them, grind them, and soak them in alkali solution to extract cotton-like substances. Then, take these things out and pinch them together to become raw gum like chewing gum. Yes, it's that simple, just soak and extract with alkali solution.
The extracted rubber raw material is yellowish, and normally it is yellow and translucent. If you want to make black tire rubber, you have to put it on a heated metal roller machine and squeeze it back and forth, and add the corresponding catalyst or ingredients into it. For example, for black tires, you have to add carbon black to the rubber raw material, which can be extracted from the tar produced by the coking plant.
After this step, fill it into the mold and press it into shape, and then put it into the vulcanization chamber for vulcanization with sulfur.
As for the last two islands that are suitable for the waterway, Luo Chong thought about it for a while and thought of a suitable use, such as a military factory.
