The freshmen were still reminiscing about themselves, and Ni Jiaqiang had already closed the computer.

"Why let you learn this history, you have to go back and taste it slowly.

Now, while everyone is here, I will give you a basic lesson on excavators, and assign the study tasks for the first month of this semester.

Everybody come with me. ”

Ni Jiaqiang walked out of the classroom after speaking, and a group of freshmen hurriedly followed.

It didn't take long for Ni Jiaqiang to lead everyone to an open field.

Parking in the open space is a medium-sized excavator three meters high and about six meters long, this excavator has a black body, and the bucket and robotic arm are slightly white, and it looks new.

Many freshmen took a look at it, and they couldn't take their eyes off it, this kind of novel excavator is completely different from the excavator driven by ordinary people in the city.

Ni Jiaqiang walked to the excavator, and with a slight drag with one hand, he lifted the entire excavator.

"This excavator weighs only five tons, but it can burst out fifty tons of power, and in some specific environments, its role is greater than that of a red mist warrior with hundreds of combat power, this is the meaning of the existence of advanced excavators.

Come, let me first introduce you to the components of the excavator......"

As he spoke, Ni Jiaqiang began to introduce the basic composition of the excavator one part at a time.

About five minutes later, he stepped aside.

"Go and see for yourselves. ”

As soon as these words came out, many freshmen immediately gathered around the excavator and began to observe this special excavator up close.

......

"I'll go! Carbon fiber body! How much does this cost?"

Wu Ideal touched the black fuselage of the excavator and sighed in surprise.

He Mu was also a little surprised when he heard this, he had some research on cars in his previous life and knew the value of carbon fiber.

Although the price of carbon fiber in this era is much lower than before, it is still very expensive.

Before the meteoric ephemeris, the price of an all-carbon fiber sports car was around tens of millions.

And now it has to sell for nearly 10 million.

Who would have thought that this excavator would also use this material.

This was unthinkable before the meteoric ephemeris, and the cost of digging up the excavator could not be recovered.

"The chassis and bucket and key parts are all bone alloys, no wonder it is so light that it can withstand the force of fifty tons!"

Another student exclaimed.

He Mu also walked to the bucket at this time, this bucket was gray-white, and it did look like a bone alloy to the touch.

Bone alloy is a new material that is made by smelting some kind of monster bone and aluminum alloy, which is lighter than steel and heavier than aluminum alloy carbon fiber.

However, its strength and hardness far exceed those of traditional materials such as steel, aluminum alloy, and carbon fiber.

Judging from the thickness and structure of this robotic arm, I am afraid that it can really withstand the force of fifty tons.

There is also the chassis of this excavator, which seems to be quite special, with many small holes around.

He Mu knew the function of these small holes after a little thought.

The excavator weighs five tons, and if the five-ton excavator really bursts out of fifty tons of power, the fuselage will inevitably warp, and these small holes are estimated to be used to grip the ground, but how it works, He Mu doesn't know.

......

"This ordinary mining type B-class excavator, the manufacturer is not profitable, the cost price is about eight million, the service life is estimated to be fifteen years, if you work every day, more than two years can recover the cost, rent, five thousand a day. ”

Seeing a group of freshmen studying around the excavator, Ni Jiaqiang stood aside and said with a smile.

Hearing this, the freshmen's eyes rolled, and they were all thinking about how long it would take for them to earn such an excavator.

"Go ahead, I'm going to drive over. ”

Ni Jiaqiang said that, turned around and walked into the distance.

As soon as he walked away, a group of freshmen couldn't hold back and began to study the excavator unscrupulously, and some even climbed between the excavator's tracks and began to observe the chassis.

At this moment, a slightly rough voice sounded next to him.

"What's the matter, your name is Wu Ideal?"

Hearing this, He Mu turned his head and looked over.

I saw that the only girl in the class was standing in front of Wu Ideal at this time, grabbing his neckline with a rather unkind expression.

Looking at the girl who was half a head taller than himself and twice his size, Wu Li also trembled a little, but when so many classmates watched, he couldn't beg for mercy, so he could only say inwardly: "What are you doing! The school rules don't allow beating classmates!"

"I know that you forced Lai Lai and me in the cafeteria at noon, Wu Ideal, right? Tell you, my name is You Dazhi! My ears are very good! I will force Lai Lai in the future, be careful that I will blow your dog's head!"

After that, You Dazhi exerted his strength violently, and directly lifted Wu Ideal above his head and turned around seven or eight times, and this scene made the surrounding freshmen dumbfounded.

"What do you see? There is no rule in the school that you are not allowed to lift your classmates!"

You Dazhi glared at the people around him, and then let go of Wu Ideal, who was completely confused.

"I'm sixty-five in combat power, and I'll be the class leader from now on, do you have any opinion?"

The freshmen were a little frightened when they heard Sixty-Five's combat effectiveness, but some were skeptical.

After all, isn't there something wrong with sixty-five combat strength coming to a vocational school?

As a result, at this time, You Dazhi walked directly to the excavator, stretched out his hands to hold the excavator, and then shouted!

"Up!"

In an instant, the entire excavator rose from the ground!

Seeing such a scene, all the freshmen couldn't help but take two steps back, not daring to say a word.

This is especially ambitious, and it is no problem for one person to beat a group of them.

He Mu watched silently beside him, and he didn't have any opinions.

No matter what position, from the squad leader to the national leader, it is necessary to do things and take responsibility.

It's not that he's afraid to take responsibility, it's that he can't afford to do anything else at this moment.

......

Not long after, a square car drove over in the distance, and there was a very obvious word "teaching" on the license plate of the car.

Waiting for the car to stop, Ni Jiaqiang got out of the car and glanced at You Dazhi first.

Seeing this, You Dazhi put down the excavator.

Looking at You Dazhi, who was like a giant mountain, Ni Jiaqiang sighed and said: "Dazhi, you are not small, it's time to pay attention to your image." ”

"Teacher, I don't have fat, it's all muscles!

You Dazhi rolled up his sleeves as he spoke, revealing a strong and huge muscle mass.

Seeing this scene, Ni Jiaqiang's wrinkled cheeks twitched, and he turned to look at the other freshmen.

"Your first month of work is to learn to drive and get your license.

After all, no matter where the excavator goes in the future, it will basically be transported by truck. ”

As soon as he said this, You Dazhi next to him said: "Teacher, can't I carry it over? It's too wasteful of time to learn to drive, just learn the excavator." ”

Ni Jiaqiang glanced at her, and said angrily: "You carry an excavator on the road every day, are you in a panic?"

Even if you have to take the excavator away in an emergency, don't you still have to carry it to the truck in the end?"

"Well, that seems to be the case. You Dazhi scratched his head and retreated.

Others have little opinion.

After all, as a man, how many people don't like cars?

However, the state has regulations that you cannot drive under the age of 18.

They all turned 18 years old after the college entrance examination, and it stands to reason that they can use the summer vacation to get their driver's licenses.

However, after the college entrance examination, the deadline for filling in the application is around mid-August.

Therefore, during the summer vacation, almost all the students of the Red Mist Warriors are trying their best to improve their combat effectiveness in order to apply for better universities, and no one has time to learn a driver's license.

......

When everyone quieted down, Ni Jiaqiang drew a box on the road.

"Today's first lesson, let's learn to reverse the car into the warehouse. ”

After that, he stretched out his hand and messed around in the group of freshmen, as if he was deciding who to teach first, point to go, point to the end, point to He Mu.

"He Mu, you come first. ”
