There was no need to survey the first ten miles, so the people marched quickly.

In order to facilitate the recording, there are two people guarding the drum car next to the car, so that it is convenient to record data at any time, and you can also take care of the body, so as not to record the drum car from being scratched by rocks or branches.

The drum cart looks like a two-wheeled wooden cart with two wooden figures holding mallets. The wheel was six feet in diameter and eighteen feet in circumference. According to the ancient standard, one step of the wheel is equal to six feet, one rotation of the wheel is equal to three steps of the car, and one mile is equal to three hundred steps, that is, the wheel turns one hundred times, that is, the travel of one mile.

There are gears connected to the wheels inside the car, and when the wheels rotate, there will be gears. When the wheel turns a hundred times, the gear drives one of the wooden men to drop the mallet and strike the small drum, that is, the drum is struck once every mile traveled.

And when the car has traveled ten miles, another wooden man will ring a brass bell with a mallet driven by the gears. In this way, according to the sound of drums and brass bells, it is possible to record how much distance traveled.

Because I was afraid of damaging the drum car, there were mountain roads in addition, so everyone walked not too fast, and this ten-mile road took nearly two quarters of an hour.

Out of the range of ten miles, the area after that, there was no careful survey, everyone cheered up, slowed down, dispersed, and began to carefully survey the surrounding grass and trees, depressions and holes.

Because it was a carpet survey, it was very slow. By noon, it would be possible to survey the surrounding area for twenty miles. Deng Yueru gave an order, and everyone found a water source and began to light a fire to cook.

Because they had just come out, everyone had brought some food with them, so lunch consisted of grilled fish made from casually caught fish, grilled dry food, and a large jar of wild vegetable rice porridge cooked in a clay pot brought by Deng Yueru.

According to what Deng Yueru said with Shuangxi, eat these things as soon as possible, and also make the horse easier.

In this regard, Double Happiness can only hide on the side and secretly enjoy.

After an hour's break at noon, everyone can sleep for a while, or they can draw the part of the terrain they have surveyed on paper first, and when they go back, they can draw a detailed map by combining the parts that everyone has drawn.

Everyone's enthusiasm was high, and after eating, everyone took out a pen and paper and drew there seriously. Deng Yueru and Shuangxi boiled hot water in a clay pot, cooled it and poured it into everyone's bamboo tube. Before that, Deng Yueru had already asked the people in the cottage not to drink raw water anymore.

After an hour, the group put away their pen and paper, got up, and continued to survey the terrain forward.

Deng Yueru chose the east side of the cottage this time, the forest is relatively dense, but the mountain is not steep, and it is not too difficult to walk.

Everyone walked slowly, and when it was time for the unitary day, even if the sun set late in summer, the forest had already begun to be a little dark.

"Sun Xing, let's get here today, it's taboo to walk in the mountains at night, let everyone come back, let's find a place to camp."

Putting away the pen and paper in his hand, Deng Yueru said to Sun Xing, who was sitting on the ground not far away.

"Okay, I'll call you all."

Sun Xing put the pen and paper in his pocket, turned over and ran into the distance.

"Miss, we're going to start living in the mountains tonight. It's the first time I've lived in the wilderness, and I'm a little excited and a little nervous. ”

Shuangxi packed up some things and led the horse to Deng Yueru's side.

"Shhhh

Deng Yueru waved her hand at Shuangxi, reached out and drew a short bow from the horse on the side, pointing to the grass not far away. She walked forward slowly, and saw a roe deer grazing in the tall grass.

"There's fresh meat to eat now."

Deng Yueru's face was happy, and she shot an arrow directly, hitting the roe deer in the neck, and the stupid roe deer fell in response.

"Miss, we can eat roe deer meat at night!"

Shuangxi ran forward, and when he saw the roe deer lying in the grass, he cheered happily.

When Sun Xing and Zhao Yong came back with people, they were also carrying two pheasants in their hands, and when they saw the roe deer on the side, their faces also showed surprise.

"Alright, let's take our prey, get out of here first, and find a place near the water source to set up camp."

In the wild, the most feared thing is that the bloody gas will attract some large beasts. However, it is early summer, and the food is abundant, so I guess it will not attract wild beasts.

By the time they were surveying the terrain, someone had already found the place where they had signaled to set up camp, and at this time everyone packed up their belongings and followed the scout and walked forward.

This side is near a small stream, and next to it are a few stout trees, which just enclose a large area, which is just right for camping.

Deng Yueru took out the medicinal powder prepared by Du Sanniang, and first sprinkled it around the camp, which was the medicinal powder to repel snakes and insects.

Then she took out another powder, which lowered the smell of blood and interfered with the beast's sense of smell, in case the smell of blood would attract the beast when they slaughtered it at the water's edge.

Sun Xing and Zhao Yong started to skin the roe deer, and some people shed their hair and washed the pheasants. Deng Yueru and Shuangxi made a pheasant mushroom soup, and then the roe deer and another pheasant were roasted directly.

All of them are scouts, and they are no strangers to sleeping in the wilderness. However, this time it was not a mission, but a survey of the terrain, so everyone did not have to worry about lightening the load, and they all brought tents, which felt like they were out camping, which was very relaxing.

Deng Yueru arranged the people who took turns to keep vigil, so that everyone could rest early.

But except for the night watchman, who looked around carefully and paid attention to safety, the rest of the people all sat around the fire, holding paper and pen and drawing carefully. Everyone knew the importance of making this map, so everyone was very attentive.

Seeing that everyone was working so hard, Deng Yueru nodded with satisfaction, pulled Shuangxi, who was infected and was ready to stay up late, into the tent, covered her cloak and prepared to sleep.

"Hey, miss, you see everyone is so serious, let's just sleep like this."

Lying next to Deng Yueru, Shuangxi's heart was very entangled.

"Everyone has to divide the labor, you see that they are so serious, they will definitely get late, then tomorrow we will get up early and make breakfast."

Turning over, Deng Yueru began to adjust her breathing and put herself to sleep.

This is what she learned when she was in the special forces, to be able to adjust her state anytime and anywhere, to fall asleep at any time, to rest and recover her strength, and to wake up at any time to participate in the battle.
