"Have you all recorded these symbols? Okay, so I'm going to introduce you to a few tools that will be the exclusive equipment of our copycat draftsmen in the future. ”

Seeing that everyone had put down their pens, Deng Yueru asked Shuangxi to bring a tray with a few things on the tray.

"Let's take a look, I won't introduce much of this charcoal, its advantage is that it is easy to carry, eliminating the disadvantage that when we use a brush, we have to bring a grinding block and a small bottle of water, which is inconvenient to use."

The first thing on the tray was a charcoal pen, and everyone had already used it for a long time, so as soon as Deng Yueru said it, everyone nodded in agreement.

"This second thing is a simple Sinan, the purpose of Sinan is known to everyone, with it, everyone can distinguish the direction more conveniently, and when drawing the map, it will not be clear about the direction of the map.

Actually, the main thing I want to talk about is this third thing, because the original is a bit big, so it's a scaled-down model. I don't know Sun Xing, Zhao Yong, do you two know about this thing? ”

Handing the palm-sized model in her hand to Shuangxi and letting her pass it on to everyone, Deng Yueru looked at everyone with a smile.

"Well, it seems to be a drum car."

Holding a model of a model and looking at it carefully, Sun Xing suddenly spoke.

"Yes, it's the Jili drum car, I heard from my grandfather before, people in ancient times drew maps, and this kind of Jili drum car was used to calculate the distance."

Zhao Yong took the model and looked at it twice, and immediately said affirmatively.

"Yes, this is the Jili drum cart, and when the scout team takes this drum cart, they will know how many miles they have traveled. In this way, the map can be more accurate. ”

Deng Yueru put the model of the drum car back on the tray, which she asked Jiang Bin to make, but fortunately, Jiang Bin still knows a little about these things, and it didn't take too much effort to make it.

Then, Deng Yueru popularized the method of judging the direction by looking at the sun and stars in the wild, as well as the growth of tree branches and leaves.

Although everyone is a scout, they are still shocked by Deng Yueru's knowledge of survival in the wild from modern special forces.

This course on ancient map painting skills and wilderness survival knowledge did not end until the end of the day, or because the light in the house was getting darker, Double Happiness made people light the candlestick, and Deng Yueru suddenly realized that it was very late.

"Okay, in fact, the skills of drawing maps are also very simple, everyone has tried to copy the map, and they have mastered these skills."

"Yes, these techniques are so practical that as long as you are familiar with them, everyone will be able to draw accurate maps."

Today, Deng Yueru talked about these knowledge, so that Sun Xingru got a treasure. He folded the paper on which he recorded the knowledge points, carefully put it in his arms, and prepared to carefully copy it into the notebook when he returned home.

In the council hall, except for Deng Yueru and Shuangxi, almost everyone was doing the same actions as Sun Xing. Everyone knows the preciousness of this knowledge, which is simply a weapon for survival in the wild.

"Okay, let's go back and digest this knowledge, and then try to draw a map to practice your hands. I'll give you a day to prepare, and the day after tomorrow, we'll set off early and start mapping the terrain of the surrounding mountains. It may take six or seven days to go out this time, and everyone is ready. ”

After explaining everything, Deng Yueru signaled that everyone could leave. When everyone was gone, Zhang Xin stood in front of her in disbelief.

"Yueru, the second uncle really doesn't know what to say. I didn't expect you to know so many things, you were silent before, you were practicing martial arts with your head bored, but it made us all underestimate your ability. Okay, you have these abilities, and the second uncle believes that you will be able to get out of the predicament with the cottage! ”

It was only at this time that Zhang Xin was really convinced.

He felt that compared with Deng Yueru, he seemed to be inferior everywhere, and sure enough, Deng Yueru was more suitable to be the owner of the village.

After parting with Zhang Xin, who was emotional, Deng Yueru stretched her waist, and then she felt that her mouth was dry.

"Of course, you've been talking all afternoon, miss, can you not be thirsty? Why don't I make you some tea?" ”

Shuangxi just wanted to make tea, but was stopped by Deng Yueru.

"Forget it, it's time for this, let's go to my father's and mother's side and drink saliva again."

At this time, the sun has already begun to set, but fortunately, it is early summer, and the sun sets late, so it will not be dark. However, torches and lanterns have been lit in the cottage, and it is bright everywhere.

When Deng Yueru came to Deng Qianshan and Du Sanniang's courtyard, there was already food on the table, just waiting for her to come back to eat.

"I'm back, I heard that you've been lecturing all afternoon, so I'm tired. Quick, drink a bowl of soup to moisten your throat first. ”

Seeing that Deng Yueru was back, Du Sanniang hurriedly beckoned her to sit beside her and handed her a bowl of white fungus soup.

The small table was placed in front of the bed, and Du Sanniang sat next to the bed, just eating and feeding Deng Qianshan by herself, without delay.

"Thank you, mother, this white fungus soup is so delicious, as soon as you drink it, you will know that it was made by your mother."

Drinking a bowl of white fungus soup in one go, Deng Yueru raised her hand heroically and wiped her mouth.

"Look at you, girls, you can't be a little gentle. What about the handkerchief I gave you last time? Can't you wipe your mouth with a handkerchief? ”

Looking at Deng Yueru's movements, the corners of Du Sanniang's eyebrows couldn't help but jump twice.

Du Sanniang wanted to train Deng Yueru to be a gentle young lady, but Deng Yueru couldn't chase her back on the road of the wild boy, which has always been a headache for Du Sanniang.

"Hey, hey, I forgot where I put that veil. Mother, don't be angry, I'll look for it when I go back, and I'll definitely pay attention to it in the future. ”

As soon as she saw Du Sanniang's eyes, Deng Yueru knew what she was going to say, and stopped the conversation with a smile.

"Oh, I'm going to starve to death. Today is a busy day, in the morning at the training ground also demonstrated the 400-meter obstacle run, in the afternoon has been lecturing, mother, you don't care about me anymore. ”

"Okay, as long as you talk a lot, let's eat!"

Du Sanniang looked at Deng Yueru's pitiful appearance, but she felt sorry for her, and sandwiched a big chicken leg in her bowl, so she laughed.

"I've heard that you're going to set off with a scout team the day after tomorrow to survey the terrain. It's going to take six or seven days, right? ”

has been fed a bowl of porridge by Du Sanniang, Deng Qianshan motioned for Du Sanniang to eat first, and he looked at Deng Yueru.

"Well, it's been decided to leave the day after tomorrow, and I'm not going to go out for too long, so I guess I'll be back in six or seven days."

Because the surrounding ten miles of land were all surveyed at the beginning, Deng Yueru and others would start to survey from ten miles away.

During the survey, the speed of travel must not be fast, and the last day or two will have to go back, so Deng Yueru estimates that this time it will be able to survey a range of about 200 miles in one direction.
