It was naturally very happy that the ten people selected by Chen Dong could come out with him this time. They couldn't hide their excitement along the way, and they kept chatting about each other.

Chen Dong brought them out this time, on the one hand, to find the ore veins, and more so to steer the surrounding terrain maps. If he drew the geometric map, Chen Dong would be able to find the location of the ore veins according to the computer in his head.

As long as you can determine which direction the ore vein is, just send a few people out to excavate.

Not to mention just looking for copper and iron, it is no problem to find a mountain of gold and silver. However, in this situation, it seems that finding copper and iron is much more important than finding a mountain of gold and silver.

If you think something is important, then it is important. If you care about him, then it is worthless. Nowadays, people do not have private property. If you dig out a Jinshan, then what if you do? Can you turn the ground or cut down trees to build a house?

"The most important thing for you to come out this time is to draw a geometric map. As long as you can find the geometric map, all the problems will be solved. This has been drawn, so you can take a look."

When Chen Dong led his men to find Chen Guo's new site, he had already climbed the mountain to draw a part of it, but this part could only select a new site for them, but it was not easy to determine the current location.

Chen Dong took those people and drew along and said, "I'll take you to get along with you first. When you are familiar with yourself, you will map all the land you can step on. In this vast world, it's not just the people of Chen. If you don't seize the power of the initiative as soon as possible, and when the outsiders invade, we will not even have the ability to resist."

These people are not the result of Professor Chen Dong. Chen Dong has never taught many things personally, a large part of it is because of their self-taught success.

Now when Chen Dong is teaching them knowledge carefully, they listen very carefully.

"See, this is a mountain. As for how high the mountain is and how wide the area is, if you can, you should record it. As for how to record it, you can find a way. Anyway, as long as you have seen it, you can understand it at a glance. This is a plain, this is a river, how wide the river, how wide the plain, you all have to find a way to accurately record it. Your misrepresentation is related to the lives of many people."

In order to save trouble in the future, Chen Dong is very attentive at this moment.

"You guys draw the map I have drawn, and then you will draw the path you have walked by yourself. I will check it when you camp at night."

At least the ten people are knowledgeable. After a few months, they have started writing a lot of words, so it is not so laborious when they put these things down again.

"Okay, keep moving forward. Since the clams have not mastered the season, I will tell you a truth first. As long as you observe more on weekdays, you will also know that the sun rises and sets in the east and the west. Judging the direction according to the sun is extremely accurate. If there is no sun on a cloudy day, you can judge based on the canopy of the big tree. The lush side is the south, and the sparse side is the north. If the north and the south are established, the things will naturally be determined.

In addition, there are many ways to judge the direction. For example, you can see the starry sky in the sky at night. I won’t tell you all these things, and it can be regarded as giving you a chance to give me a surname.”

Chen Dong had a computer in his brain, which had millions of ways to determine the direction, but he was too lazy to tell them one by one, but he called it to give others a chance.

The ten people could not have thought that Chen Dong was unwilling to teach them in detail because he was lazy. Chen Dong had already told them the directions of the southeast, northwest and north, which was enough to make them curious.

"It is the first time you have come into contact with these. You don't have to hurry and walk slowly in a few days. You are familiar with it slowly. You must be clear when drawing a geometric map, that is, you must pay attention to safety. Be careful of the sudden attack of wild beasts. In fact, don't be afraid of them. There is no beast that you are not afraid of in the fire you are using now. I hope that one day, the beasts can walk around you." Chen Dong said as he walked.

The ten people didn't listen to what Chen Dong said at all, and they were all focused on learning from the southeast, northwest, high mountains, plains, rivers, etc.

These people took the initiative to learn from Chen Dong, and they were of some interest and talent.

After a few days, the ten people were basically all getting started, and they could accurately draw the place they walked on the geometric map.

As soon as they saw that they had learned almost everything, Chen Dong began to take them back, "Okay, since you have learned it, then go back and repair it, and you can come out alone. For safety, you can get along with a few people from home, and go back to regain your life every once in a while, and integrate the geometric maps you have drawn together. There are only two requirements for you. One is to pay attention to your own safety and not be in danger, and the other is to ensure that the geometric maps you have drawn are accurate."

Chen Dong was actually just looking at the scenery this time, and he didn't do anything. Instead, the ten people who poured out didn't care about looking at the scenery at all, and all his attention was on drawing a geometric map.

Chen Dong has been teaching them for a while and has a general understanding of those who learn knowledge. Naturally, he also knows that these ten people are among the top thirty people, hoping that among them, an excellent geologist can be produced.

Now Chen Dong only needs to understand the realm he is in now.

At the beginning, Chen Dong thought about taking people out to find mineral veins. Later, he thought about it and let it go. Now Chen Dong has been walking less than fifty kilometers, but he has been traveling through mountains and rivers, so tired that he is dying. If he only relies on him to lead people out little by little, he will have to go to the Year of the Monkey and Horse Month.

When Chen Dong took the man back the same way, he reminded him: "By the same way to return to this free time, you can also confirm whether the geosam easing map you have drawn is correct. Every inch of land here will be stepped on by humans again."

This advice was indeed useful. Many people were making changes when they went back, and Chen Dong turned a blind eye to this.

I don’t know the time and space that Chen Dong is familiar with. How long did the ancestors of human beings take to draw the first geometric map, but in this time and space, Chen Dong thought that it only took less than a year for them to draw a geometric map from literacy to now being able to draw a geometric map, and this speed is already considered fast.

When Chen Dong brought his group back, Mu had already brought his wife and children. His wife was not very beautiful, with rough and dark skin, but she smiled when she saw someone. When she smiled, she had a row of white teeth. She was a woman who was easy to get along with.

"I took it, I've settled, right?" Chen Dong asked with concern.

"Well, we have settled down. Thank you, King Ping, for allowing us to wait for the family to reunite." Mu Nidao continued.

"Let's live a good life, take good care of them. It is an innate responsibility for a man to protect his wife, children, and young people. In this way, it is better to choose a day than to meet the day. Tomorrow, we will hold a lively wedding for you and let you be together with you dignifiedly. How about it?"

King Ping was even more grateful to Chen Dong's arrangement. He pulled his wife and children and kowtowed.
