I use the learning system to engage in technology

Yuan Jiang didn't understand why Song Yao had to come out at first, and why the leader agreed.

Even though the security level of D country is not low, as someone who has been protecting Song Yao, Yuan Jiang doesn't want to see any risks. Why must he come to D country? If he wants to see more things, there are so many cities in Zhongzhou, right?

But since Song Yao has made a decision, Yuan Jiang supports him as always.

When he saw the corpse, his first reaction was to block the children's eyes, but thinking that there was more than one corpse in the ruins, Yuan Jiang still forced himself to freeze his body and tried to use a calm tone to reduce the impact they faced.

But when he saw Song Yao, who would cry loudly if he lost a fight with a pig, said nothing, just pursed his lips and passed by the corpse, and carefully studied the machine used for earthquake rescue, Yuan Jiang realized that this child who had been in the protection circle chose to step out of that circle.

Song Yao has never seen a corpse.

The first time he saw such a terrifying scene, he should have been afraid, and in fact he was really afraid, but he just forced himself to move normally.

But when he was checking the excavator, he saw from the corner of his eye that the man was kneeling on the ground crying, carefully and carefully tidying up the lady's messy hair, and he even put the broken hairpin back on her.

A little boy cried and handed over a tattered sheet. They worked together to wrap the woman up. The man carried his wife on his back, held his son's hand, and slowly walked away.

Song Yao closed his eyes and suppressed his tears.

He didn't know where they were going, but he knew that from this moment on, a family was broken.

The child felt sad for the family and felt deeply scared.

It was just a little bit.

It was just a little bit, and Changle would become like this.

The earthquake zone in Changle was full of positive hope. Everyone worked very hard because no one died and no one lost their loved ones. Maybe everything on that land would be damaged, but as long as people were still there, there would be hope.

But the earthquake zone in D country is full of grief. Even strangers who have no relatives here can feel the deep heaviness when standing in this area.

This is the weight of life that cannot be ignored.

Whenever Song Yao thinks that Zhongzhou will face such a situation in the original history, his hands can't help but tremble slightly.

History courses don't describe much, but with such a terrible earthquake, and late at night, how many people will lose their loved ones like the man and the child just now?

The shaking hand was held by Zhao Xiaodong.

The child looked up and saw that Zhao Xiaodong was obviously very scared, but he still insisted on having a pale face and tried to comfort him: "Little boy, don't be afraid, it's all over, let's go help."

"You are right, it's all over."

The Changle Sorrow has never appeared, and what they have to do is to change other disasters that may occur in the future.

Song Yao re-firmed his expression: "I found that this machine can improve the track. Let's go and get the tools."

After arriving at the earthquake zone in person, Song Yao realized how naive his previous idea that "long strips can explore living people and machines can lift heavy objects" was.

Of course, the machine can lift any heavy object, but the key point is whether there is a person under the heavy object.

After the earthquake, all the places where they are standing now are made up of ruins. Everything in the ruins is unstable, but they support each other. Sometimes moving one of the seemingly small objects can cause a secondary collapse.

So the rescuers dare not move randomly. Before rescuing people, they will calculate various angles and carefully use many tools to ensure the safety of the people below.

The name of the translator of country D is very long. People in Zhongzhou are used to calling him Matthew. Some people still think his last name is Ma.

Matthew has a typical Western appearance, white skin and a high nose bridge. When he talked about this, his eyes were always red:

"At the beginning, everyone had no experience, which led to many people who could have been rescued being trapped forever.

Although there were many earthquakes in their country, they were all small earthquakes. A big earthquake like this one directly shocked more than half of the people, and many rescuers were volunteers.

Everyone's first reaction when hearing the call for help was to rescue people as soon as possible, but who knew that good intentions would do bad things, which also left many rescuers with psychological trauma.

Song Yao heard about this kind of earthquake zone rescue knowledge for the first time. After all, Zhongzhou had a cultural fault due to war. The first major earthquake after the founding of the country was Changle. Because there were no people in the earthquake zone who needed rescue, they could naturally do drastic things when rebuilding Changle.

He didn't know the original history. In the course of history, did Zhongzhou have the same thing as D country when rescuing Changle? But what is certain is that he did take it for granted before.

Song Yao not only found Matthew to understand the situation, but also participated in several rescues, helped calculate the places that could be moved, and brought people to improve the rescue machines.

D country was also very cooperative, giving tools and equipment, even if the person who made this request was just a child who was very young in the eyes of Westerners.

A rescuer from D country was curious and asked Matthew. Matthew didn't know the specific identity of Song Yao, but he had a good impression of this smart and helpful Zhongzhou child, and he immediately praised him:

"I heard that they are college students from a very famous university in Zhongzhou, and they are also scientists. This time they were called by Zhongzhou to help us."

The listeners were surprised, looking at the eyes of these children, they were shocked: "They are so young, are they college students?"

Even in country D, those who can go to college are other people’s children.

Matthew explained: "They are exceptions because they are smarter than other children. It is also because of this that they were sent to country D."

The people of country D were even more moved.

Since this disaster happened in their country, when it comes to which country has tried the hardest to help, Zhongzhou ranks first. Now even young geniuses from their own country are sent to help them. In any case, this kind of sentiment will be remembered by many In the hearts of Chinese people.

No matter which country they are in, adults are always much friendlier to children. Even if they don't understand the language, Song Yao and the others can feel that these D-country people are very friendly to them.

When eating, they would spontaneously step back and let the people from Zhongzhou eat first. The uncle from country D who was in charge of cooking would give two full spoonfuls to people from Zhongzhou every time he saw them. When it came to children like Song Yao and the others, he would also hand them over with a smile. Give them candies that are popular in country D, and tell them they are very sweet with gestures.

This is a very novel experience. People of different skin colors express kindness and support each other. It feels very good to have this kind of kindness reciprocated. At least Song Yao likes it very much.

Creation may be difficult, but improvement is simple for Song Yao. Based on the current terrain of the ruins, he successfully improved the rescue machine in just one day.

Not only can it now climb up the ruins, it is also equipped with many long-arm-shaped iron blocks. When necessary, these iron blocks can replace the stone supports that need to be removed, creating a safe space for the people underneath.

At the same time, it also comes with a lighting function, which can be conveniently operated by people on the ground.

This is the best rescue shape that Song Yao used in a simulation laboratory and experimented nineteen times in just five hours. Although it is ugly and looks like a monster, it is indeed very suitable for such occasions. Easy to use.

Because of the complex terrain, the people above could not figure out what to do to maximize the safety below. Therefore, the people who had been trapped had this improved rescue machine and finally saw the light of day again.

After transforming it, Song Yao continued to improve his strip non-stop.

At the beginning, his positioning of Chang Tiao was to find the living. In this rescue operation, Chang Tiao did a good job in completing this task, although not every living person it found could be successfully rescued.

It is now the eighth night of the earthquake, and no survivors have been found in the areas that Chang Tiao can reach, but this does not mean that there are no survivors, it is just that Chang Tiao cannot go to many places.

Matthew said: "Actually, we all know that this is already the eighth day. Without food or water, people will not be able to survive this day. But everyone does not want to give up and is still looking for survivors every day."

"There are still many people whose family members are missing. They don't sleep, eat only a little food, and search every day. We don't know if they can be found, but we know that we can't stop them at this moment."

Song Yao tightened the last screw on the long strip that had shrunk and looked more like a small snake: "I understand that I will look for a new long strip again."

Even if the probability of someone surviving is one in ten thousand, if you give up, what kind of despair will it be for the person who has worked so hard to survive.

Just like the Changle earthquake, the probability of successful earthquake prediction was not high at that time, but just for that small probability, Zhongzhou relocated all Changle people overnight.

Song Yao was also willing to continue searching for that little bit of hope. Maybe it was just a waste of time, but the child was more willing to waste time than there might be someone waiting for them to rescue.

The child who was very afraid of snakes did not resist this time and made the strips look like snakes because it would be easier for them to find.

After seeing it, Zhao Xiaodong had only one question: "Yao'er, why did you add such a thick iron block to its head?"

Song Yao touched the iron block and said, "I want to use it to send messages. Let's try it first."

After touching it twice, the child felt that the snake with iron blocks looked even scarier. Especially for better lighting, its mouth was still slightly open. Even without teeth, it looked like it was about to bite people every minute.

Even though he was the producer, Song Yao, who was afraid of snakes, retracted his hand a little timidly, even afraid to hold it.

Now it looked like a small snake, but without scales. Song Yao found a gap and was about to put it in. Then he looked at the long snake that looked more like a snake. Thinking of something, he stood up and shouted people:

"Brother Matthew! Help me!"

Lilian didn't know how long she had been trapped here.

There is no concept of time in the dark underground. She was lucky to have been in the kitchen during the earthquake, so she had some water and food on hand, but she was also unlucky to be buried very, very deep.

Lilian didn't know exactly how deep it was. It was pitch dark at first. She knew she had to conserve her strength, so she didn't call for help. She just hit the same frequency with a stone from time to time, hoping to be discovered.

At first, Lillian was full of hope. She was not seriously injured. There was water and food around her, and she could wait for rescue with peace of mind.

But as time passed, the darkness never changed, and Lillian began to fall into panic.

She couldn't hear a sound, but that didn't mean there was no sound from the outside world. If such a terrible earthquake occurred, the government would definitely rescue her. Lillian finally realized one thing, she might be trapped in a very deep place.

She began to try to shout for help and continued to use stones to transmit her voice, but there was no response, not even a single response.

Food and water were slowly consumed no matter how sparingly they were used. Lillian herself didn't know that she hadn't drunk water or eaten for three days. She was extremely weak, her throat was sore, and her eyelids were heavy.

The darkness without a single ray of light made her see no hope, and the dead silence around her filled her with despair. Lillian clearly understood that she was about to die in this dark place where no one knew.

But she didn't want to die. She was only sixteen years old this year, studying here alone. Her parents and relatives must be very worried about her, and they would never give up on her.

But sometimes, Lillian would also think that maybe many days had passed outside now, maybe they thought she was dead, and no one would have thought that she was still alive after such a long time.

The two emotions were mixed, and Lillian became weaker. She lay on the cold ground, looking at the darkness ahead with unfocused eyes.

She thought, her time has come.

- Dongdongdong.

Faintly, Lillian heard the sound of knocking stones in the distance, and she was stunned for a moment.

——Dongdongdong.

Lillian slowly supported herself and crawled in that direction, trying hard to listen.

There was really a sound.

It seemed to come from a distance, not very real, but so clear in this silent space.

——Dongdongdong.

Lillian's heart was pounding, she tried her best to pick up a stone, and used the little strength in her body to knock on the stone: Dongdongdong!

The three steady knocking sounds outside suddenly stopped.

Lillian held her breath, not daring to put down the stone in her hand, and continued to knock. She knocked very eagerly, afraid of missing this sudden hope.

After a long time in her eyes, there was still no response from outside.

At this moment, Lillian collapsed and wanted to cry.

But she had long lost her tears.

She held the stone tightly and continued to knock hard.

Until suddenly, the sound that seemed to be right next to her ear rang: Dongdongdong.

Still three times, not too fast or too slow, with just the right interval.

Lillian looked up suddenly, and she suddenly realized that the other party was following her voice because of the silence just now. She hurriedly knocked harder, opened her mouth, and tried to speak with her voiceless throat: "Ah——"

——Help me!!!

——Please save me!

——I'm

Above, Song Yao was stretching his legs, and Zhao Xiaodong in the tent suddenly rushed out: "Little one!! There is a signal!! Someone is responding below!!!"

Song Yao stood up suddenly, and not only him, but all the people in Zhongzhou looked over here.

The people of D country didn't understand, and didn't know what they were excited about, so they went to ask Matthew, and after Matthew translated, they were also excited.

Song Yao had already rushed into the tent, and a machine for checking signals was temporarily built inside. It was originally equipped with a long strip, and now it was widened by one layer.

"Have you figured out the depth position?"

"It has. The internal support structure needs to wait for the strip to go around all the way." Zhao Xiaodong handed the recorded data to Song Yao: "We can get these data now."

Song Yao looked at it carefully and breathed a sigh of relief: "We can start digging on the ground. The risk of collapse is very small. Give me the manipulator and I'll see if I can get in."

Underground, Lillian found that the knocking sound outside had disappeared again, but there were more rustling sounds, as if something was circling around.

She was a little confused and calmed down a little. These movements did not sound like what humans could do, especially those knocking sounds were very regular, but there was no sound of people talking.

But what could it be?

A few minutes later, Lillian saw a beam of light for the first time in a long time.

Her first reaction was to close her eyes. Even though Song Yao adjusted the brightness very low, for Lillian, who had been in the dark space for so long, she had to open and close her eyes for a long time before she could barely adapt to the sudden light source.

After finally being able to see what was in front of her, Lillian was stunned.

Is this a... glowing snake?

The iron block on the top of the long snake's head was a little worn because it kept hitting the stone gently, and its body was covered with dirt, but this did not prevent it from shining in the dark.

While glowing, it circled around Lillian, swaying its body, and turned one side of its body towards her.

Lillian then discovered that there were words written on it, and those light sources just happened to allow people to see what was written on it:

[Hello, please don't be afraid of my appearance, I am a Zhongzhou rescue snake, we are rescuing you, please be patient. ]

Then it turned to the other side:

[Also, I don't bite people^_^]
