Chapter 317 Drawing a Map (Please vote and subscribe)

After the Sharp Horn Tribe joined, Luo Chong asked them to stay in Hanyang City temporarily to rest. At the same time, he summoned all the natives of Hanyang City during dinner and asked them who was willing to move to the new city.

There is only a rammed earth wall in the new city now, and nothing else. There is no place to live, and there is no land. Not only do you have to build houses there, but you also have to open up new farmland. The workload is quite heavy, but it is not without benefits.

In the civilian residential area of ​​the new city, each house covers an area of ​​16.6×16.6 meters, which can build five main rooms, independent kitchens, and even south rooms and east and west wing rooms. The area is almost twice as large as that of Hanyang City, so there are still many tribesmen willing to move there. After all, who doesn’t want a bigger house at home, especially those families with many people.

In this way, more than 70 families agreed to move to the new city area. The tribesmen of the Sharp Horn Tribe were divided into 130 households, 80 of which were willing to move to the new city area, and the remaining 50 moved into the empty houses vacated in Hanyang City.

These tribesmen who were about to move to the new city area had jobs in various workshops. After arriving in the new city, they could quickly organize the newly joined tribesmen to start construction and put the new city area on the right track.

Luo Chong took advantage of this period of time to let the woodworking workshop quickly make a set of windmill automatic sawmill parts and let them take them to the new city area to build a new workshop. At that time, the wood processing in the new city area would no longer need to be transported from Hanyang City. They could make it themselves as much as possible. At the same time, they also brought a lot of grain seeds and farm tools so that they could open up farmland there.

After these people set off with a lot of things, Luo Chong asked Shouya, Shuda, and Xuetu to take people to each tribe to deliver sickles to help them quickly harvest food. After all, they couldn't afford many sickles before. Letting them harvest by themselves would definitely slow down Luo Chong's immigration plan.

With the instructions handed down one by one, the increasingly large machine of the Han tribe was running in an orderly manner under the command of Luo Chong, the leader.

With the increase of the population of Xincheng and the increasingly heavy labor tasks, it was time to send a general manager there. Luo Chong thought about it for a long time and finally decided to send Dashu, who was mining in Babaoshan. Dashu had been with Luo Chong for a long time and Luo Chong trusted him. At the same time, Dashu also had the ability to lead thousands of people. When Luo Chong was not in Hanyang City before, he had always let him be the temporary general manager. He

did it as soon as he thought of it. With this idea, Luo Chong directly sent a letter to summon Dashu back by flying eagle, and asked Yufeng, who was still in the tribe, to take over Dashu's position in Babaoshan. Dashu went back to Hanyang City directly, and after giving him some instructions, he asked him to go to Xincheng as the general manager. At that time, he would also replace Youye, the guy, because Luo Chong had other uses for him.

This guy likes to run around like his elder brother. At first, Luo Chong asked him to set up a new market, and he was very happy. But after such a long time, he gradually realized that this market was different from his brother's. His brother could run around, but his market was fixed, which made him feel more and more boring. He just watched those people work every day and then paid them wages.

Since this guy wants to run around, let's satisfy him.

After several consecutive attacks by the cannibals, this time they even hit the door directly. Although the final result was not bad, it still made Luo Chong feel a great sense of crisis. So Luo Chong wanted to send an elite team to the north for reconnaissance, find the location of their lair, and see if they could deal with them, preferably to wipe them out.

It is still difficult to completely get rid of them. Now the biggest goal is to be able to scout the enemy situation.

At the same time, this elite team is not only responsible for reconnaissance, but also for drawing maps, so that Luo Chong can understand it when the time comes.

It has been almost two years. Luo Chong has never asked anyone to draw a map except for a rough map in You Fu's hand, because the Han tribe has never had such conditions, but now it can.

Don't think that drawing a map is a simple thing. If you want to draw a map that can be used, you don't know how difficult it is. The draftsman must not only understand mathematics, geography, but also ruler and compass drawing. These are all very important. Otherwise, you can draw whatever you see? That's called a map?

Before the Japanese invaded China, they didn't know how many years they had prepared for the map. All of them were their spies who pretended to be members of the Chamber of Commerce and measured step by step on the land of the motherland.

If you want to draw a map, the most important tool is the compass, that is, the compass or the north needle. Without this thing, how can you tell the exact direction? The direction determined by looking at the sun can only be an approximate direction. It's confusing to use it to draw a map. I don't know how far it will differ from the actual terrain.

Fortunately, the Han tribe now has the materials for making compasses, bronze, magnets, and now they have them.

The diamond-shaped pointer is made of pure steel, and then it is directly rubbed with natural magnetite to make it magnetic. Then, a round copper plate is cast with bronze in a ratio of 1:1 between copper and tin. Using a copper plate as a base is the most suitable material at this stage, because copper does not produce magnetism, so the magnetic needle will not be affected when placed on it, and the displayed direction can be more accurate.

The copper plate is the size of a palm, with a diameter of nine centimeters. It is embossed with eight directions, including southeast, northwest, southeast, northeast, southwest, and northwest. There is also a circle of 360-degree scales. There is a small hole in the center, which can be used to fix the magnetic needle, and a small iron rod can be inserted. When the magnetic needle fails, the direction can be determined by observing the shadow of the small iron rod in the sun.

This function is actually very useful. For example, when encountering magnetite in the salt lake in the north, the strong magnetic field will cause the magnetic needle to fail, and the function of the magnetic needle will be finished. However, the sun will not be affected by the magnetic field, so it is safest to look at the shadow.

After making the compass, Luo Chong had someone make a beautiful wooden box to hold the compass. He also used a wooden stick to look at the shadow to find the south and north, which is the direction with the shortest shadow during the day. By confirming the south and north, Luo Chong also found the magnetic declination of his planet. In this way, the compass can be really used. Spring,

summer, autumn and winter, as the planet revolves around the sun, the time may change and the shadow may lengthen, but the direction of the shadow is the same regardless of the season, which is the safest.

Now that we have the compass, the next step is to make other preparations for drawing the map, especially the benchmark, which is an indispensable item for drawing the map. Finally, we need to select personnel for training and learn some simple geography and mathematics knowledge.
