In the experimental building of the School of Mechanical Sciences of Shanghai University.

Mr. Xue walked ahead and led the way, while Liu Wenping followed.

Behind them were a group of short men with work signs hanging on them with the words "Yangtze Science and Technology" written on them.

"This is our metal flaw detection laboratory." A teacher introduced to these people.

A man led by the exchange group of the Tokyo University of Technology walked straight in, glanced at the equipment inside, and sneered: "What era is this? You are still using such backward equipment, we have long eliminated."

His Mandarin is OK, but he has a strong accent.

Hearing this sentence, the teachers in the school looked very good.

The School of Mechanical Science at Huhai University is not the strongest department. Not to mention comparing with top foreign universities, it is not even possible to compare with some domestic universities.

If the funds are a little weak, you cannot buy some powerful equipment.

Many equipment in the laboratory are outdated equipment, barely enough for teachers and students in the school to do research and use.

Sometimes, if the School of Mechanical Engineering wants to use a high-precision microscope, it has to go to the School of Materials to apply.

Everyone knows these, but now they are ridiculed by Japanese people, and everyone feels uncomfortable.

"The Mechanical Institute of Shanghai University is just like this." The Japanese man said with a disdainful look and walked out of the laboratory.

"Let me see what other equipment you can take out." The boy continued.

Wang Zhao, who was standing beside him, couldn't help it and said angrily: "Haruto Yamaguchi, you have the ability to go to other schools. Don't you just think we are easy to bully!"

The boy was the representative of this exchange group, named Haruto Yamaguchi, and was a graduate student at the Tokyo University of Technology.

"What's wrong with this classmate, we bullying you?" Yamaguchi Haruto said disdainfully.

The Japanese people behind them all showed mockery on their faces.

"The top five in Shanghai University in China, I didn't expect that the School of Mechanical Science is so trash!"

"I'm so embarrassed to say that we bully you, we're bullying you!"

"Our Japanese Science and Technology is not inferior to any school in terms of finishing processing!"

Several Japanese people shouted.

Wang Zhao looked angry, and his fists were clenched, but he couldn't say a word.

It is an eternal truth that they will be beaten when they fall behind. They are here today to bully people.

In order to mock them, these people actually learned Mandarin specifically.

Mr. Xue said slowly: "Don't quarrel, it's a fact that our equipment is not good, so we have to work harder."

"Even if you fight, you will never catch up with us!" Yamaguchi Haruto sneered.

Now even Mr. Xue's face became a little unhappy.

"See the next laboratory!" Liu Wenping said quickly.

If you are not as skilled as others, you can only swallow your anger.

"We used this device last century, but I didn't expect you to still use it!"

"My God! The age of this machine tool is already available to our museum!"

"What kind of students can these ragged things teach?"

Whenever he arrived at a laboratory, Haruto Yamaguchi started to talk big.

Mr. Xue and Liu Wenping's faces became even more embarrassing.

After visiting the laboratory, everyone came to a conference room.

Haruto Yamaguchi put the bag in his hand on the table and took out a small black box from it.

"Dear teachers and students of Shanghai University, the friendship between our Japan University of Technology and Shanghai University is indestructible. Don't take what I said before to heart. After all, what I said is the truth." Yamaguchi Haruto sneered.

"That's natural. Our Shanghai University is willing to deepen exchanges with the Tokyo University of Technology and make progress together." Mr. Xue said with anger.

No matter what, these are international friends, so you can't make any mistakes.

"I also said I would give you a gift, and now I will take it out for you to see." Yamaguchi Haruto slowly took the small black box in his hand and opened it immediately.

A black box is padded with a soft cloth inside.

A heart-shaped metal workpiece is placed in the box.

The surface of this workpiece is polished very brightly, reflecting the surrounding scene, glowing with iron gray, and is obviously made of steel alloy.

"This is the gift we give you, symbolizing that we are connected to the heart of Shanghai University and that friendship lasts forever." Haruto Yamaguchi said with a hint of proudness.

"Take it to them," Yamaguchi Haruto ordered.

A student stood up behind him and took the heart-shaped workpiece in front of Mr. Xue.

Mr. Xue took the workpiece and looked at it carefully, with a puzzled look.

"Student Yamaguchi, why is there a hole in the center of this Taoxin?" Mr. Xue couldn't help asking.

The surface of this peach heart is smooth, with three sides in total, two sides are flat, and one curved surface around it, forming the shape of the peach heart, showing extremely advanced surface processing technology.

But there is a circular hole in the center of the peach heart, which directly penetrates the entire peach heart.

The hollow looks smooth on the naked eye, as if a hole was made specifically.

A smile appeared on Yamaguchi Haruto's face: "This is a gift I left to Shanghai University. I want to ask Shanghai University to match this heart with a screw. After screwing the screws on, it can make up for this void and be perfect with the surface.

Fit."

"The heart of peach is naturally not beautiful incomplete. Only a complete heart can represent the heart-to-heart connection."

After Yamaguchi Haruto finished speaking, all of Shanghai University were stunned.

"Isn't this just a round hole? Just cut a cylinder and stuff it in. Why do you need to use screws?" Wang Zhao said in confusion.

"That's right, how can I get screws? I don't even have threads!"

"Without thread, how do we get screws?"

Several other students also asked in confusion.

Liu Wenping took the Taoxin workpiece and turned on the flashlight on the phone and shine it on the hole.

There is actually a metallic luster reflected on the hollow inner wall.

This means that the processing accuracy inside this hole is really terrifying.

But no matter how much he looked at it, Liu Wenping didn't notice how a screw was stuffed into it.

In modern industry, screws and nuts are the most commonly used fasteners and have different specifications. You can just put the nuts and screws of the same specifications on them and screw them.

The one on the screw is called the external thread, and the one on the nut is called the internal thread.

Without internal threads, even if you make a screw, you can't screw it up.

"Student Yamaguchi, there are no threads on this?" Liu Wenping said in confusion.

"The teachers and students of Shanghai University seem to have a good look, but that's all I said. If I have to remind you about this, I have to wonder if your Shanghai University rankings are full of moisture." Yamaguchi

Qingren sneered.

The group of Japanese people sat here without moving, looking at the Shanghai University opposite with contempt.

Mr. Xue suddenly remembered something and said sternly: "Come here with a microscope!"

A student ran out quickly and soon came over with a portable microscope in his hand.

This portable microscope is about the same size as a camera and can be enlarged by hundreds of times.

Mr. Xue immediately pointed the camera at the inner wall of Taoxin.

It doesn't matter when you see it, but it's shocked.

The inner wall is densely covered with tiny threads.

Wang Zhao and Liu Wenping were lying behind, and many students looked at the screen together.

It looks mirrored to the naked eye, but at this moment there are tiny threads, surrounded by circles, and the spacing between the teeth is very small.

This is seen under a microscope. It is very small, so how small should these threads be?

"Damn!" Wang Zhao couldn't help but shout.

The other students all made a "dream" sound.

"How can I get screws so small?" Wang Zhao said in confusion.

"Our equipment cannot achieve this accuracy." Liu Wenping also said.

Yamaguchi Haruto sat opposite him with a smile on his face, enjoying this feeling quite a bit.

Japan is the best in finishing processing, and is definitely not comparable to that of Shanghai University.

They don’t expect Shanghai University to make screws.

"Student Yamaguchi, let us go back and study this thing." Mr. Xue said slowly.
