Chapter 580 I’m so jealous of Lu Jiansen!

As soon as Gu Xiaoxi stood still, all the students below fell silent.

No one really expected that the teacher teaching them would be such a young and pretty girl.

But some people who had helped Gu Xiaoxi unload wood yesterday widened their eyes in surprise, obviously recognizing Gu Xiaoxi, so they all looked towards Lu Jiansen.

Of course, some people were surprised and thought it was too much of a joke for the school to ask a little girl to teach them.

But because Director Kang came in with Gu Xiaoxi, no one said anything and just waited for Director Kang to speak.

Director Kang did want to say something, so he stood beside Gu Xiaoxi and said to everyone: "Professor Zheng has asked for leave today, so this class will be taught by your teaching assistant Gu Xiaoxi. Maybe some of you already know that she was not only a doctor at Qingbei Military Hospital, but also worked at the Qingbei Military Industry Department. This time, the three provincial military industry departments jointly invited Dr. Gu to serve as your teaching assistant..."

After listening to Director Kang’s introduction, all the students were amazed.

Some people were talking in low voices, while others looked unconvinced, thinking that Director Kang's words were a bit exaggerated.

Gu Xiaoxi didn't care what other people thought. After Director Kang finished his introduction, she just said a few words and raised the atmosphere in the classroom by several degrees.

"Hello everyone, I am your teaching assistant Gu Xiaoxi. The fact that I can stand here shows that I know more than you. Whether you are learning with an open mind or wasting your time, I will only say what I say once. If you don't understand, that's your problem."

In the classroom, some people laughed.

If they don’t understand, it’s their problem?

Couldn't this be the teacher's problem?

There were two teachers attending the class who looked at each other with smiles in their eyes.

The little girl is young and energetic. Even experienced teachers like them don't dare to say this to the students.

"Mechanical engineering has many principles, and it would take too long to explain them all. Professor Zheng has a more systematic way of explaining these principles. You should listen carefully to Professor Zheng's lectures. Today I will teach you how to read mechanical drawings..."

The foundations of the students present here are actually different. Some people think that Gu Xiaoxi is teaching something so difficult right from the start, which is too difficult for those who have just started learning.

But some people think that it is too simple to just look at a mechanical drawing and there is no need to learn it.

But when Gu Xiaoxi picked up a piece of chalk and drew a watch on the blackboard without any tools, as if it was a copy of a real watch, everyone was stunned.

Apart from anything else, how many people can draw a watch dial so quickly and well with their own hands, and make it look so lifelike?

"Everyone knows that this is a watch. Mechanical watches are familiar to everyone, but how many people know what its internal structure is?"

When the students heard this question, they started discussing it.

Gu Xiaoxi let them discuss for a while, but did not ask anyone to answer questions. Instead, he pointed to the watch and said, "The first thing we see is definitely the dial. The hour hand, minute hand, and second hand on them rotate on the dial driven by the mechanism to indicate the time..."

"Its external components, as far as the case is concerned, are made of many materials, such as stainless steel, gold, titanium alloy..."

“However, its movement can be disassembled into the mainspring, the balance spring, and the escapement mechanism…”

As Gu Xiaoxi spoke, he drew the various parts of the movement on the blackboard.

Anyone who has taken apart a watch will find that what Gu Xiaoxi drew on the blackboard is almost identical to the real part.

The only difference is that the drawing on the blackboard is magnified dozens or even hundreds of times.

“Some people may think that you should learn more advanced mechanics and there is no need to look at the structure of this watch. But I want to say that if you learn to disassemble the internal components of a watch and know how to be complete and fully functional, when a watch stops working, you will know what is wrong with it…”

"On the other hand, once you understand the structure of a mechanical watch, it will be easier to read other drawings..."

Most of the students had already taken it in by now and understood the disassembled and complete diagrams of the mechanical watch on the blackboard.

They were shocked in their hearts, for they had never seen anyone who could draw so many different pictures so easily and so well.

Even Director Kang, who was sitting at the back of the classroom, looked shocked.

He seemed to suddenly understand why Gu Xiaoxi could come to Xining Military Academy as an assistant teacher at such a young age.

His drawing skills alone are far superior to many people.

"I just disassembled a mechanical watch for you because it is something you have come into contact with and is relatively high-end. You are all soldiers, and now we are going to disassemble the structure of a gun..."

Speaking of weapons, the soldiers weren't sleepy anymore and all of them sat up straight.

Lu Jiansen looked quietly at the little girl on the podium, his eyes filled with nothing but pride.

His wife is awesome!

After explaining the gun's structural diagram, Gu Xiaoxi gently erased the mechanical diagram on the blackboard and drew a structural analysis diagram of a cutting machine.

After teaching three different types of mechanical drawings, the class lasted more than an hour.

In the last twenty minutes, Gu Xiaoxi drew a structural analysis diagram of a military truck for everyone, focusing on the structure of the car engine.

"Okay, there are too many parts used in a car. In addition to the engine structure, there are also transmissions, chassis, etc. We will discuss the detailed drawings of these parts and the analysis methods in the next class. Class dismissed!"

As soon as Gu Xiaoxi finished speaking, warm applause broke out in the classroom.

Regardless of whether everyone gained anything from this class, this group of military academy cadets really recognized Gu Xiaoxi's ability.

They didn't actually understand some of the things, but that didn't stop them from developing a strong interest in learning mechanical drawings.

After Gu Xiaoxi left the classroom, someone immediately took off his watch and prepared to find tools to take it apart and take a look.

Someone even said with a smile: "Let alone other things, even if you learn to repair watches, it is also an amazing skill!"

"Hey, let me tell you a little gossip. I heard that Assistant Professor Gu has even assembled cars, and more than one..." someone suddenly said in a low voice.

“Is this true or false?”

"Of course it's true. She doesn't even know how to assemble a car, so how could she draw such a detailed car structure?"

"I will definitely listen carefully in tomorrow's class..."

"Me too……"

"What do you mean tomorrow? I just checked. Assistant Professor Gu has one class on Tuesday and Thursday mornings, both lasting one and a half hours, and one on Saturday afternoon. She has no class tomorrow."

Just when everyone was disappointed, someone suddenly exclaimed, "Ah! I'm so jealous of Lu Jiansen!"

Lu Jiansen, who had just walked out of the door, paused slightly, and then quickly quickened his pace.

There are no classes in the morning, so he has to go home to be with his wife and children!
