I use the learning system to engage in technology

Song Yao saw the small group of soldiers that grandma mentioned at noon.

They found a place to repair outside the village, and Song Yao and Zhao Xiaodong hid behind a tree to peek.

Grandma Song was right. This group of soldiers was indeed very young. Song Yao even saw one with a particularly tender face who looked younger than his brother who was sixteen or seventeen years old in their village.

Zhao Xiaodong pointed to a tough man who was obviously the leader of this group of soldiers and said:

"My dad was like that."

Song Yao looked over, his mouth widening into an "O" shape in surprise:

"Wow, your dad is so awesome."

Zhao Xiaodong was extremely proud.

The two children were not experts in hiding, so the soldiers discovered them as soon as they sneaked over.

When they found out it was two children, they didn't try to expose them.

But they were peeking, chatting, dancing, and pointing at them from time to time. Isn't it too arrogant?

When Song Yao was comparing to Zhao Xiaodong how tall and strong he would be in the future, someone suddenly appeared in front of him. When he looked up, he saw the tall person he was comparing to standing in front of them.

The tall soldier picked them out one by one, as if they were carrying little chickens.

"What are you doing here?"

He put the two children down carefully, and although his tone was serious, it was not cold either.

The two children, who felt they had done something wrong, hesitated and did not dare to tell the truth.

The tall soldier laughed and touched their heads:

"The wildfire is still burning. Stop running around. Go home and wait until the wildfire is completely extinguished before you come out to play."

Finding that although he looked very cold and tough, his attitude towards them seemed to be quite good, Song Yao's courage started to rise again.

He raised his head curiously and asked, "Uncle, why didn't you bring water and only a shovel?"

The tall soldier's body was covered with dirt and mud. He smiled and shook the dirt from his legs. While shaking, he said:

"The fire is so big that unless it rains, it will definitely not be extinguished with water. We dug around the fire. Without trees and grass, the fire cannot burn."

"This is called a fire break. You can also use this method if you encounter wildfires in the future."

Song Yao nodded obediently.

After the tall soldier finished explaining, he let them go:

"Go home quickly, don't stay outside."

Song Yao was reluctant to leave. This was his first time meeting the People's Liberation Army. Not counting Zhao Xiaodong's father, he had not yet joined the army when he met Zhao Xiaodong's father.

The child was brave enough not to leave. He whispered: "I don't want to go home. Can we just watch you here?"

After he finished speaking, he poked Zhao Xiaodong, trying to get him to say a few words.

As a result, Zhao Xiaodong was so excited because he was picked up by the soldiers himself that he didn't pay attention to Song Yao at all.

So Song Yao could only say to herself: "Is it hot for you? I have a hand-cranked fan at home. Can I bring it over to cool you down?"

The tall soldiers knew about the water-powered fans. They had heard about them even in the army, saying that they came out first in Xinghe County.

Although it requires water for driving force, the attached equipment can circulate the water flow, and the strong wind power makes it suitable for a group of people to use, so it is very popular in major factories.

I have never heard of a hand fan.

Of course they had never heard of it. The hand-cranked fan was only used by Song Yao to practice his skills. Although it was very successful, it had to be said that it was useless.

It is very small, so it cannot stand on its own. It needs to be held with one hand, and the other hand needs to keep shaking the rocker. The wind produced is about the same as a fan.

So why don't you just use fans if you are pragmatic?

What else can I do with my hands free?

So the hand-cranked fan was stranded. At most, sometimes Grandpa Song and Grandma Song couldn't use their hands when working, and they felt hot, so they would call Song Yao and Dad Song to hand-crank the fan.

But most of the time, they would rather stay warm.

Especially now that Dashu Village has a water-powered fan (yes, it was the first one made by Song Yao and the others), which is placed at the door of the school's classroom. Everyone will naturally go there if they feel too hot.

I heard that in the area where the county magistrate placed water-powered fans for the whole county, some people would go there and lay paving floors in order to cool down at night.

Hand-cranked fans naturally become waste products.

Now, Song Yao has found a good use for it.

The two children rushed home and took out the small fan, and then ran over to fan the soldiers who were busy digging fire breaks.

The tall soldier persuaded them several times, but they still insisted, so they stopped trying.

In fact, such a small fan can blow a lot of wind, but seeing the two little cubs caring about them so much without saying anything, the soldiers felt quite warm in their hearts.

Carrying wildfires is physical work.

Because people are racing against wildfires, they can't work during the day and sleep at night. They can only take turns to rest, but they don't dare to rest for too long. They have to get up before sleeping for four hours and continue to join in the task. Wildfire queue.

Like Grandma Song, the people in the village were very grateful to these young soldiers, but it was a pity that they refused to accept the food sent by everyone, and sometimes they would drink water such as water that did not cost money.

So Song Yao volunteered that he and Zhao Xiaodong could deliver water to the troops.

Zhao Xiaodong, who always likes to be lazy, is also very active this time.

Maybe it was because of his father, or maybe it was because of the influence of adults, he admired soldiers very much. Sometimes he brought water to the tired soldiers, and when he saw them drinking the water he brought, they were so happy that they kept talking all the way.

Song Yao was actually similar.

He thought the PLA was amazing, their discipline, their upright posture, and they worked harder than the villagers to carry fire.

Recently, except for tinkering with his life-saving necklace, Song Yao was always around this small group of soldiers.

He also knew that they were very tired, so he didn't make trouble, but tried hard to help them. Sometimes when he saw a soldier falling to the ground and sleeping, he would run over to help cover the quilt.

Song Yao was cute and sweet-mouthed. When everyone was busy, he was sensible and well-behaved, and when everyone was not busy, he would not toss around. After a few days, the soldiers liked this child very much.

But after all, he was old and tired every day. The way they liked was to touch Song Yao's head and share their rations with him. They really couldn't squeeze out time for other things.

The youngest soldier in this small group of soldiers was more energetic than the others.

Because he was young, the other soldiers took extra care of him and didn't assign him the more stressful tasks, so he was the only one who could spare time to chat with Song Yao and Zhao Xiaodong.

He said that his hometown was Changnan, and he had been in the army for two years. His name was Liu Xiaohu.

Liu Xiaohu showed Song Yao and the others his arms that were gradually becoming stronger:

"Don't look at me as thin, I exercise every day in the army, and now I have muscles on my body."

Of course, he was still not as good as their captain, but he was already very satisfied.

Song Yao and Zhao Xiaodong's eyes were bright: "Wow!!"

They pinched Liu Xiaohu's arms as if they were looking at some great hero, and their eyes were full of little stars in envy.

Liu Xiaohu smiled honestly and a little proudly, letting the two children touch him all over.

Song Yao asked curiously: "Brother Xiaohu, how can I become like you?"

He always thought that he was a good-looking man until he became friends with Zhao Xiaodong. Every time they went out to play, it was like the elder brother taking the younger brother.

Song Yao doesn't have the obsession with height that an adult man has, like the county magistrate, but he has begun to consciously pursue height growth.

Liu Xiaohu scratched his head and said uncertainly:

"Eat enough and exercise more every day. I used to eat too much at home and often didn't eat enough. After joining the army, I can eat enough and train with everyone every day, so I gradually became stronger."

He said: "I have grown a lot taller."

Song Yao nodded and secretly decided that he would eat more and exercise more in the future.

He looked up and saw the clothes Liu Xiaohu was wearing under his military uniform, and asked curiously:

"Brother Xiaohu, it's so hot, why are you wearing such a high collar?"

He saw that other military brothers and uncles were wearing short sleeves inside. When they were close to the wildfire, everyone would take off their military uniforms and put them away to avoid being smoked.

Liu Xiaohu looked around a little embarrassedly and whispered:

"I have a scar on my neck. It's scary to show it, so I wear clothes with high collars to cover it."

When he said this, his face was full of embarrassment: "I once scared a child to tears."

Song Yao and Zhao Xiaodong were not scared by what he said at all. Instead, they were more curious:

"What scar? Can it scare a child to tears?"

Seeing their eager faces, Liu Xiaohu thought about it and said to them: "Then I'll show you, don't be scared."

He reiterated: "It's really scary. Sometimes I feel ugly when I look in the mirror."

Song Yao and Zhao Xiaodong immediately agreed.

Song Yao patted his chest and said: "Don't worry, brother Xiaohu, I have seen the scariest and scariest things in the world."

He was lifted up by his mother before!

Liu Xiaohu slowly rolled down his collar.

After the collar no longer covered his neck, a hideous scar was revealed on it.

It is just below the Adam's apple, with a thick protrusion. At first glance, it looks like an uneven earthworm. It is indeed visually shocking when you see it suddenly.

However, Song Yao and Zhao Xiaodong are both brave, and they often get injured.

They fell down when they ran too fast, bumped into the neighbor when climbing a tree, and bumped into others when playing games.

They are rural children.

They have been injured a lot since they were young.

Song Yao used to cry a few times when he was injured when adults were around, and when adults were not around, he would pat the dust off his body and get up by himself, and continue playing as if nothing had happened.

This year, he began to feel that he was a little genius, so he gradually cared about his image and didn't cry if he could.

Zhao Xiaodong was even more so.

He had never healed the injuries on his legs since he was a child. The front leg was just healed, and the next leg would come back with injuries after a day of playing, especially the knees, which had scars on them.

So the two of them just opened their eyes a little wider and were not scared.

Song Yao thought of another aspect: "Such a serious injury, you must have felt a lot of pain at the time, right?"

Liu Xiaohu smiled shyly: "I didn't feel much pain when I was injured, but it was quite uncomfortable when I recovered."

He said: "I was lucky that my trachea was not injured. The doctor who treated me at the time said that if the knife had been cut a little higher, I would have died."

Song Yao and Zhao Xiaodong were extremely surprised.

"Why did a knife cut your neck? Did you fall while cooking?"

Speaking of the origin of this scar, Liu Xiaohu is still a little proud:

"Last year when I went back to my hometown, I saw a bad guy bullying a girl. I went up to fight with him, and he was the one who made the cut with the knife."

Seeing that the two children looked shocked, he quickly added:

"I didn't lose. I had already pushed him to the ground, and he attacked me in a sneak attack."

He didn't really know it himself, but according to the girl, when the knife went down, his neck was covered with blood, and she thought he was going to die.

This was the first time Song Yao and Zhao Xiaodong had heard of such a thing.

Zhao Xiaodong's family is a family of martyrs, and no one will provoke them.

Song Yao's family had some gangsters looking for trouble, but before anyone else in the village came to help, Song's mother beat them up and threw them out.

According to his father, the legend of his mother is still circulating in the county to this day.

This was the first time they saw someone injured in a fight with bad guys.

After the two of them calmed down, they looked at Liu Xiaohu with admiration in their eyes.

Song Yao looked at him with eyes full of admiration: "Brother Xiaohu, you are so brave and powerful, you are a hero!"

Zhao Xiaodong nodded repeatedly: "I think so too."

Song Yao pointed to the scar on Liu Xiaohu’s neck and said, “This is the scar of a hero!”

Zhao Xiaodong: "I think so too!"

Song Yao: "If this were placed in our county, your deeds would definitely spread throughout the county."

Zhao Xiaodong: "Yes! I think so too!"

Liu Xiaohu smiled sheepishly:

"But it's still scary. You should cover it up if you can. Anyway, it's not troublesome to wear an extra layer of clothing. It's only a hot spot in summer. It's fine in other seasons."

Song Yao said, "It would be great if this scar could be removed."

But he also knew that it was unlikely. As a normal child with constant scars, he had a lot of insights into scars.

It is impossible to expect such a big scar to disappear on your own.

But maybe it will be possible in the future.

005 also said that even if people in the future break their legs and arms, they can still get new ones.

Although the scars will still be covered in the future, Liu Xiaohu was still very happy with the praise and admiration from the two children, Song Yao and Zhao Xiaodong.

So a few days later, after the mountain fire was completely extinguished, leaving only a few pitch-black mountains and dug trenches, the troops completed their mission and were about to leave. He even came to say goodbye to the two of them.

"Our army is in Huling County next door. If you go there in the future, you can come and play with me. I have a day off."

Song Yao and Zhao Xiaodong nodded repeatedly.

Then Song Yao took out a belt (?) with a cautious look on his face. Anyway, it was a long belt-like or a very wide belt loop, and handed it to Liu Xiaohu.

Liu Xiaohu picked it up and looked at it with a strange look on his face: "This is...a belt without a mouth?"

Zhao Xiaodong immediately had a look on his face that said, "Let me tell you."

"Yeah, it looks like a belt!"

Song Yao became angry: "It's just a little wider!!"

Liu Xiaohu immediately comforted him: "It's okay, the belt will be useful if it is wider."

Song Yao: "..."

The child was extremely sad and angry: "This is a life-saving necklace!! It's not a belt! It's a necklace!!"

Liu Xiaohu gestured with confusion: "Is it such a thick... necklace?"

Song Yao: ...Okay, it's a little thick.

But no matter how detailed it is, it really won’t work.

In fact, what he wanted to do was really not like this.

According to Song Yao's idea, it should be both beautiful and practical, and it should not be uncomfortable at all when worn around the neck.

It's beautiful to think about, but it's different when you make it.

Song Yao spent a lot of effort just to figure out how to make it quickly inflate after being filled with water.

After finally completing this step with alien technology, a new problem came. He did not have the kind of material that expanded with inflation.

No matter how hard Song Yao worked, even asking Teacher He started to have a headache. According to the current conditions and Song Yao's knowledge, he could not create a material that could grow bigger out of thin air.

So this necklace changed from the original "()" to "()".

Although it has a life-saving function, who would be willing to wear this thing in the summer?

Song Yao put a set on his little neck, and it fell directly to show what it meant to be a size discrepancy.

He took it to his father again.

Song's father thanked Bu Min and said, "No, I can swim, so it won't be a problem if I wear this thing."

Then take it to other people in the village.

Interested children cannot wear it.

The adults wearing them are not interested.

They don't like playing with water, so why do they want this thing?

Those who love to play in water can swim. If according to Song Yao's words, as soon as they are submerged in water while wearing it, it will immediately expand and make people float, then how can they have fun?

It's not even okay to wash your hair in the river.

So after Song Yao made it, he marketed it around, but no one wanted to wear it.

The child was very disappointed.

This is the first time he has made something that is not popular.

After trying to sell it several times but still failing, he had to tell Zhao Xiaodong: The life-saving necklace plan failed.

Because it’s not practical, no one wants to use it once it’s made.

Even if it is worn as a necklace, everyone still finds it ugly and hot.

Originally, Song Yao planned to keep it at the bottom of the box.

But didn’t he meet a new friend, Liu Xiaohu?

He needed to cover the scar on his neck, and the other necklaces were too small and not tight enough to cover it, but his life-saving necklace was just the right size! !

Song Yao, who consciously found a good owner for his life-saving necklace, was very satisfied.

In order to buy the materials used to make this necklace, he emptied his small coffers, and even pestered his father for some money to barely make up for it.

Although he won't use it, it's a good thing not to waste it.

Song Yao taught Liu Xiaohu to put it on: "This is not an ordinary necklace, it is a life-saving necklace."

The child suddenly became alert: "You don't know how to swim, do you?"

Liu Xiaohu looked blank and shook his head: "I don't know how, what's wrong?"

Song Yao breathed a sigh of relief: "That's good. As long as you don't go swimming, it won't pop out. You can also wear it in the shower. If the pressure isn't enough, it won't pop out."

Liu Xiaohu didn’t quite understand: “Isn’t this a necklace?”

Song Yao: "But it's not an ordinary necklace!"

The child explained to him seriously: "Actually, this is an underwater life-saving necklace, specially prepared for people who can't swim. If someone doesn't know how to wear the necklace, it will fall into their hands.

As soon as the water reaches the neck, it will automatically pop open and float with the person up. "

Song Yaochao was very proud: "Although the whole body cannot rise, the head will be floated, and it will definitely not drown."

Liu Xiaohu: "..."

He felt that the child Song Yao was making it up, how could such a thing exist in the world.

Song Yao saw his blank expression: "Don't you say something? Although it's a bit useless, it's amazing that I can do this!"

Liu Xiaohu: "Uh... wow?"

Song Yao: "...Okay, just use it as an ordinary necklace. It'll be good for covering your scars."

Liu Xiaohu nodded. He thought that this ugly necklace didn't look like it was valuable. Besides, he had already become friends with the two of them, so he didn't refuse.

"Okay, thank you, I will always wear it."

This is the first time he has received a gift.

The half-grown young man happily touched the thick and tight necklace around his neck and boasted without conscience:

"I think it's pretty."

Song Yao and Zhao Xiaodong were both shocked.

Oh my God, brother Xiaohu actually thinks this necklace looks good.

After Liu Xiaohu returned to the team, Song Yao quietly said to Zhao Xiaodong: "I didn't expect Brother Xiaohu to have such bad taste."

Zhao Xiaodong expressed his agreement.

When the army left, Song Yao and Zhao Xiaodong came to see them off.

Not only them, almost the whole village came.

Everyone stood at the entrance of the village watching these young soldiers leave and waving their hands.

Song Yao's little hands were so cheerful.

This is his first military friend.

In the team, Liu Xiaohu touched the life-saving necklace around his neck. After returning, his companions said it was ugly.

But after all, it was given to him by a friend.

And it’s better to be ugly than scary.

He still hasn't taken it off.

The young soldier thought optimistically. Anyway, if you keep being ugly, you will get used to it.

The wildfire did not bring much damage to Dashu Village, but Yanwei Village lost a lot of houses and food. There was nothing they could do when faced with such a natural disaster. They could only borrow some food from relatives and friends.

If you work harder next year, you will be able to recover.

A relative who lived in Yanwei Village also came to Song Yao's family. He should be called his aunt. Grandma Song comforted her and borrowed some food before sending her away.

Children were not allowed to listen to such miserable topics. Song Yao could only continue fanning the clock with Zhao Xiaodong in the yard.

After his aunt left, he couldn't help but think of Liu Xiaohu.

Father Song said that the fan business has been booming recently, and almost all the orders in this county have been booked, so he set his sights on the neighboring Huling County very ambitiously.

After analyzing and planning for two or three days, Song’s father packed his luggage and prepared to leave.

Song Yao helped diligently and waited for his father to finish cleaning up before saying:

"Dad, if you pass by Brother Xiaohu's army, can you help me take this over?"

The child handed Dad Song a beautiful fish scale.

This was what he picked up next to the fish he killed last time at home. It can show the colors of the rainbow in the sunlight.

A friend of Song Yaochao said fondly: "Brother Xiaohu said that he has never eaten braised fish. This fish is braised. He can't eat it. He will be happy just by looking at the fish scales."

Dad Song: "..."

He felt that the young soldier would not be very happy.

"If you can't take it with you, you should keep it yourself first and give it to yourself next time you have a chance."

Song Yao clung to her father eagerly:

"Why can't I take you with me? Dad is the best. Dad, I like you the most. Just help me take him there. Didn't you say you're on the way?"

Dad Song refused:

"We really can't take them with us. There was a big flood in Suliu. Their entire army was deployed to fight the flood. They are not in Xinghe County at all."

Song Yao was stunned.

He knew that Zhao Xiaodong’s father died fighting the flood.

Brother Xiaohu actually wants to fight the flood?

Will he die?

The child himself was startled by this question, and then he suddenly remembered that Brother Xiaohu was wearing the life-saving necklace he gave him.

If he fell into the water, he would definitely not drown.

He breathed a sigh of relief and patted himself comfortingly.

Fortunately, he thought the necklace was ugly and didn't keep it for himself to wear when he grew up.

Fortunately, Brother Xiaohu has poor eyesight.
