I use the learning system to engage in technology

When the cries spread outside, Grandma Song was sewing insoles with Grandma Zhao.

When Grandma Zhao heard her grandson crying and wanted to go into the house to have a look, Grandma Song stopped her:

"You heard them crying so loudly, and they didn't call anyone, so it's probably nothing."

With the cleverness of these two children, if something really happened, they would definitely not just howl like this.

Grandma Zhao was still a little restless.

After all, since the death of his son, it is not an exaggeration to say that Zhao Xiaodong is the eyeball of the mother-in-law and daughter-in-law, because they are afraid of bumping into each other.

But it turned out that Grandma Song was right.

A few minutes later, Song Yao and Zhao Xiaodong appeared with red eyes.

The two of you pulled each other and stepped on you, but no one complained to the adults. After sitting down, they started working honestly again.

Grandma Zhao was relieved and sighed to Grandma Song:

"Since playing with your Yao'er, our Dongdong has improved a lot than before."

Although Song Yao can be a little naughty sometimes, his intelligence is incomparable to his sensible peers. Grandma Zhao wishes her grandson could play with him every day and pick up more good habits.

The person involved, Zhao Xiaodong, felt extremely aggrieved: "If you weren't my friend, I wouldn't care about you."

Song Yao originally didn't want to continue working, but seeing Zhao Xiaodong's unwillingness, he felt proud:

"Don't you want to make something awesome again and let everyone praise us?"

Zhao Xiaodong muttered: "Then we don't have to do it every day. We are still children and we have so much time to use. Why are we in such a hurry?"

Song Yao was shocked: "Do we have a lot of time to use?"

Zhao Xiaodong was stunned by his question and said uncertainly: "Isn't it?"

"Of course not!"

Song Yao stretched out her fleshy little hand to count for him:

"We have seven hours of classes from Monday to Friday, and the get out of class lasts ten minutes, which is one hour a day. It takes an hour to eat breakfast, lunch and dinner, and it takes half an hour to go back and forth to school.

We have to sleep for an hour and a half at noon, do homework for an hour in the afternoon, we have to spare an hour and a half to play, and it takes another half an hour to wash our faces and brush our teeth in the morning and evening..."

Song Yao himself was shocked by the calculated results.

He was shocked: "We have to be busy at least fourteen hours a day!"

The child continued to count on his fingers: "We get up at six o'clock and go to bed at nine o'clock in the evening, that is... fifteen hours!"

Zhao Xiaodong was confused: "Then we only have one hour a day to use it?"

God, are they so busy?

Song Yao also had a serious look on his face: "This doesn't include the time we spent in bed."

Zhao Xiaodong: "..."

He was shocked for several seconds, and his IQ went up: "But we don't have to go to school on Saturdays and Sundays."

Song Yaorong said confidently: "It's because we don't have to go to school that we have to do things in these two days. Otherwise, if we only spend one hour a day, how long will it take to make the fan clock and life-saving necklace?"

Zhao Xiaodong: "Wait a minute, what kind of life-saving necklace?"

Song Yao was stunned: "Didn't I tell you that we are making life-saving necklaces?"

Zhao Xiaodong: "..."

He groaned angrily: "What did you say to me? You asked me to work as soon as I arrived at your house, and I worked all morning without even knowing what I was doing."

Song Yao was surprised: "Then why didn't you ask me?"

Zhao Xiaodong: "..."

He forgot.

Realizing that he seemed to have a problem, Zhao Xiaodong quickly changed the topic:

"Tell me first what this life-saving necklace of yours is. Is it the thing you mentioned yesterday that can prevent people from drowning?"

Sure enough, Song Yao's attention immediately shifted and he said proudly: "Yes, that's it."

He should be proud.

Because from a practical perspective, there is no course on life-saving necklaces in the learning system.

There are many "old" life-saving bracelets, life-saving bubble underwater rescue machines and other technologies.

But after Song Yao read the details, he knew he couldn't do it.

It's the same reason as before, he doesn't have the tools.

Moreover, these technologies are for the future after all. Song Yao, who already has research experience, knew at a glance that if he wanted to succeed, he would have to keep practicing and conducting various experiments.

In other words, a lot of raw materials are also needed.

The fact that Song Yao was able to get the iron nails was already favored by the Song family, not to mention all the high-end things above that he didn't even know existed in this era.

So after searching hard for a long time, the child came up with a sudden idea and decided to integrate the two technologies in the learning system.

In the interstellar age, each planet has its own traditional culture that is very useful, and some interesting producers will include it by the way.

One of the planets is very good at underwater supplies. Even during the feudal dynasty of their planet, they were able to build an underwater pavilion using only manpower.

Even after entering the technological age, various products from their planet are still very popular. When people travel, they will buy some as gifts for relatives and friends.

The producer went to that planet for three or four years to eat, drink and travel. He also packed a lot of production skills with food and drinks. When making the learning system, he stuffed it in by the way.

The course purchased by Song Yao is one of them.

The other is the underwater life-saving equipment commonly used by Chinese people in Zhongzhou about three hundred years later.

He planned to combine the two courses and learn from each other's strengths.

Song Yao confidently took out his design drawing and handed it to Zhao Xiaodong to see:

"Look, this is a good idea, isn't it?"

Zhao Xiaodong didn't really want to see it.

But he thought about it and felt that Song Yao had made so many design drawings, so he should have made progress, right?

So he reached out and took it, looked at it, and looked at it again.

The nine-year-old child collapsed: "What are these strips above??"

Song Yao: "Can't you understand?"

Zhao Xiaodong nodded honestly: "I don't understand."

Song Yao raised his head proudly: "You're right if you don't understand, because this is knowledge beyond our time."

Children are super confident.

Hum, this is the fusion of different technologies from two planets more than three hundred years later and more than three thousand years later. Of course, it is not so easy for others to understand.

Zhao Xiaodong: "..."

He lowered his head and looked at the blueprint in his hand.

After struggling for a long time, I finally managed to say: "I don't think anyone can understand it, right?"

Song Yao was even more proud: "Of course, if everyone can understand it, then what's the point of being ahead of the times?"

Zhao Xiaodong always feels that this has nothing to do with transcending the times.

But Song Yao was so confident that he was a little unsure.

Song Yao is the smartest kid in the village.

Every time Teacher He tests them, Song Yao always gets the first place.

With Song Yao being so confident, he increasingly doubted whether he really couldn't understand it because he wasn't at that level.

Zhao Xiaodong struggled in his mind for a full minute before he said hesitantly:

"Okay, then I don't understand. Please tell me."

Song Yao started talking to him about bala bala.

"You still remember the buoyancy we learned last time, right? Why do people drown when they fall into the water? Because they can't float. Wouldn't it be great if we just make something that can make people float in the water? "

Zhao Xiaodong thought what he said made sense and nodded: "Then how do we make something that makes people float?"

Song Yao waved his hand: "It's not easy to make people float. A boat can make people float."

Zhao Xiaodong: "...You're not trying to make a boat, are you? The river in our village can't accommodate it."

"Who said we were going to build a boat? I was just talking about the principles of boats. Let me tell you, I read the book Teacher He asked us to read yesterday, and it mentioned buoyancy. Here we go..."

After Song Yao finished sharing his great plan, everyone in Zhao Xiaodong was already numb.

Seeing that his friend kept talking, he raised his hand and said, "I have a question."

Song Yao, who still had a lot to say, stopped regretfully: "You say it."

Zhao Xiaodong: "Are you dreaming?"

"How can there be a necklace that can explode when it hits water? My grandma had a necklace. When I threw it into the water when I was a child, it would just sink in and stay there."

Song Yao had never seen a necklace before, and he was a little curious: "What next?"

Zhao Xiaodong looked sad: "Then my grandma beat me up."

"So it is absolutely impossible for the necklace to unfold when it encounters water. Moreover, if the necklace is so small, it will probably be very small when unfolded. What's the use of it?"

Song Yao was not hit at all, he was still very confident:

"You don't understand. Buoyancy is very magical. As long as the necklace expands to a large enough volume and the density is light enough, it will definitely work."

Zhao Xiaodong was a little confused when he heard this: "What volume and density?"

He could barely understand Fuli, but what does all this follow?

Song Yao felt a little guilty: "I don't know, that's what the book says anyway."

Zhao Xiaodong always felt that he was still fooling himself: "I don't believe it, the teacher never taught us this."

"Then let's ask the teacher. It just so happens that I don't understand a bit."

Song Yao originally planned to try various styles of things today to see who could float faster in the water. Now that he told Zhao Xiaodong, he also felt that he should solidify his theory first.

The two children left as soon as they were told, and ran out in a hurry:

"Grandma, let's go find the teacher!"

Teacher He is reading a book.

She felt miserable during the first hour of reading.

Over the second hour, she gradually sank into it.

In the third hour, she felt that her soul had been sublimated.

You can even drink water and read a book comfortably.

Teacher He thought, is this the power of knowledge?

So fulfilling, so secure.

In fact, if you think about it carefully, this is not bad. At least it will never happen again that you cannot answer the questions asked by students, and you have to write letters to classmates you haven't seen in two years for help.

And there is no need to worry about classmate Ye Xinghua being venomous.

Teacher He took a sip of water and successfully comforted himself.

Ah, what a beautiful day.

"teacher!"

The duet of Song Yao and Zhao Xiaodong suddenly came from outside the window, and Teacher He was so frightened that he almost spit out the sip of water he had just taken.

She tried her best to swallow the water calmly: "What's wrong? Didn't you say you were going to study it yourself at Song Yao's house today?"

The two children entered Teacher He's cabin by familiar means:

"Teacher, the expansion of objects is related to gas, right? Hydraulic buoyancy...density...volume...Does a ship float because it is hollow? And teacher, a book mentioned this yesterday...but only One sentence, I brought the book, teacher, look at it..."

Teacher Ho:"……"

She picked and answered her own questions.

Song Yao proudly said to Zhao Xiaodong: "You see, what I thought was right."

Zhao Xiaodong made a face at him: "Then you can't explain it clearly. If it weren't for the teacher, you wouldn't know where you are right."

Song Yao was not convinced: "That's because today's experiment hasn't started yet. If it does, I will definitely be able to do it next time!"

Teacher Ho:"……"

She had a bad premonition: "...are you making something new again?"

Song Yao proudly puffed out his chest: "Yes, we want to make something that can float people in the water!"

Teacher Ho:"……"

She smiled stiffly: "Aren't you going to fan the clock?"

Song Yao had a "Yeah, so what's the matter" expression on his face: "We can do it together."

Zhao Xiaodong hummed: "If he hadn't begged me, I wouldn't have done it with him."

After humming, he suddenly realized: "Hey! Is it time for us to eat?!"

Song Yao also exclaimed, and then enthusiastically invited Teacher He:

"Teacher, you can go to our house for dinner."

Zhao Xiaodong squeezed him away: "Teacher, don't go to his house, go to my house."

Teacher Ho:"……"

She wanted to go (after all, it was a bit sad to eat her own food), but she couldn't go.

She smiled: "Teacher has something to do, so I won't eat with you. You go and eat first."

The two children didn't think much, nodded and went out: "Thank you teacher, let's go then."

They even closed the door very thoughtfully.

Teacher He waited for his two students to pass by the window, then quickly opened the drawer with a solemn look on his face...

Take out the envelope and start writing.

The letter was sent out the same day it was written, and it took five days before it reached Ye Xinghua.

He opened it happily and looked at it with a solemn expression on his face.

Last time when classmate He shared with him that two children had made a water-powered fan, he felt that these two children were smarter than he thought.

As a result, now, they have actually shifted their position to buoyancy.

The current problem was of course no problem for Ye Xinghua, but he saw the amazing learning abilities of these two children, especially the junior classmate Song Yao.

Ye Xinghua felt a little sense of urgency.

Lesbians all like knowledgeable people.

Now that he can answer these questions, if that classmate Song Yao suddenly changes his studies to something else one day, he can't tell classmate He, right?

Ye Xinghua wrote the reply carefully and tried hard to say, "These are just minor questions. Don't worry, I'm very knowledgeable. Just ask me." After carefully checking it several times, he sent the letter.

Then he turned around and went to the school library and borrowed several books at once.

A classmate from the next door dormitory came over for a walk at night:

"I told you that a man fell into the river yesterday while riding a bicycle..."

As soon as he entered the house, he was shocked.

Ye Xinghua was reading with a serious look on his face. He had a densely written notebook under his hand. There were several books with very profound names beside him. There were a few pieces of tea leaves in the cup to refresh himself.

The classmate was stunned. He had never seen Ye Xinghua in such a posture.

Aren't his grades very good? It seems like I haven’t had any exams lately.

He lowered his voice unconsciously and carefully asked his roommate Ye Xinghua next to him:

"what happened to him?"

My roommate also whispered: "He is chasing a lesbian."

classmate:"……"

He was in awe.

It turns out that this is how people with good grades pursue lesbians.

No wonder I don't have a partner... No, that's wrong.

No wonder it's so strong!
