In a daze, Jiang Jiuling felt that someone was talking to him.

"Jiang Jiuling, you also have to understand our school's side. ”

"You also know the damage caused to the school by that incident, and the medical expenses of the three of you, which add up to almost 100,000 yuan, or the money I asked for from the Education Bureau. ”

How did I get involved with the school, and the medical bills?

Jiang Jiuling, who has graduated from university for six years and was invited to participate in the 107th anniversary celebration of his alma mater as an outstanding student of the Department of Industrial Engineering last year, was a little confused at this time.

When he opened his eyes, an office with a very old-fashioned layout appeared in front of Jiang Jiuling.

Next to the jujube red desk piled with papers, sat a middle-aged man with gray hair and a slight brow, as if he was thinking about some difficult problem.

There is also a row of display cabinets erected behind the middle-aged man, and through the glass, Jiang Jiuling can see that the display cabinets are full of all kinds of awards and trophies.

One of the largest medals reads:

[1991 Comprehensive Education Assessment.]

(Excellent School)

Wu City Education Bureau

April 1991]

Perhaps sensing Jiang Jiuling's curious gaze staring at the medal, the middle-aged man with a scholarly temperament on his face at the desk said with some heartache: "Just because of your incident, the school's excellent school selection for seven consecutive years has also been yellow. ”

"I know that none of you three should be too responsible for this. ”

"The responsibility must be borne by our school, after all, you are in the school. ”

"Originally, the investigation team of the Education Bureau didn't blame you for this matter, but now the Industrial Committee is also involved, and they want to investigate the cause of the damage to the [Wang Mang-level vernier caliper]. ”

"Now that the school has made the decision to expel the three of you, isn't it protecting you?"

“......”

What is Wang Mang's vernier caliper, and what is it worth investigating by the Industrial Committee?

How am I here?

Didn't I stay up late in the office to write the [2019 National Practical Industrial Patent Publicity and Promotion] document, I was exhausted by working overtime for two consecutive days, and after the document was completed, I simply lay down in the office and slept beautifully.

Now the office I am familiar with is gone, and the important document related to the propaganda caliber and industrial direction of many industrial parks across the country by 2019 is gone.

Instead of a very old office, listening to the tone of this middle-aged man, he was still injured and hospitalized at school?

And then expelled from school?

Why is this dream so realistic?

Jiang Jiuling couldn't help but feel dizzy for a while, and subconsciously knocked his head with his hand, trying to wake himself up from his dream.

Hiss......

It hurts.

I didn't wake myself up, but I felt an old wound in the back of my head that was visibly painful.

The pain had just hit, and the memory in Jiang Jiuling's mind seemed to be suddenly connected, and some vague pictures emerged from the depths of his memory.

It's 1992.

I was seventeen years old.

The person in front of him is none other than Feng Rong, the principal of his high school.

Himself was expelled from school.

The reason is that three months ago, he and two other students formed a science and technology interest group called [Crimson Arc].

The three people in the group, including Jiang Jiuling, are all students with strong hands-on ability in the school.

And this science and technology interest group was formed to build a robot chariot.

In 1992, in addition to watching cartoons, many teenagers also liked to chase a show, the "Robot Chariot Arena" program organized by the British TNN TV.

This show is popular in many countries around the world, and the cool battle scenes of those robot chariots in it have become the coolest dream in the hearts of countless teenagers.

Of course, Jiang Jiuling knows that this has been held for more than ten years, and it still has many die-hard fans in 2019. But it's gone, and it no longer has the obsessive charm of the nineties.

But those dazzling kings who once dominated the ring and tore their opponents to pieces are still remembered by countless people.

Robo-Knight.

Firemen.

Rubber bugs.

Yellow spider.

Sharp arrows.

Future Battleship ......

The memory in his mind now tells Jiang Jiuling that the time and space at this moment is 1992.

This can't be my own memory, I was a two-year-old baby in ninety-two. In addition, the show Robot Chariot Arena, if I remember correctly, I should have seen it on TV in 97 or 98.

Doubts about the anachronism are soon interrupted by the explosion in memory.

That's right~

The Crimson Arc Technology Interest Group also wants to build a robot chariot, and then travel across the ocean to the United Kingdom to participate in the robot chariot competition show.

The show is very high-tech, and the rules of the competition are that the two contestants use their own robot vehicles to fight in the ring. In the ring, in addition to various mechanical traps, there are also four robots that are not limited by weight.

In addition to remotely controlling their own robot chariots to fight, the two contestants completely tear the other party apart. Also keep an eye out for traps and attacks from powerful bots. The degree of excitement of the show is unparalleled.

The three people in the Crimson Arc Interest Group are all loyal fans of this show, and they have just won the first prize of the Municipal Youth Science and Technology Innovation Competition for the school, and their mentality is so bad that they can't do it.

Then I don't know who is ambitious and says that it is better to strike while the iron is hot and build a real robot chariot to win glory for the country.

This plan quickly received strong support from the principal, who not only ran down 3,000 yuan from the Education Bureau, but also set aside a room in the laboratory building for the Crimson Arc Interest Group.

In the words of Principal Feng Rong, I don't expect you to win the award, as long as you can let the robot pass the pre-competition audition and appear on this show.

When your robot chariot is built, I will personally bring you to England.

Principal Feng Rong's intentions are good, the robot chariot competition has been held for two years, and has been reprinted and broadcast by more than 20 national TV stations so far, and there has never been a robot chariot led by Chinese people.

If the students of their Wucheng No. 3 Middle School could appear on the show with a robot chariot, what would the scenery become?

Even if you can't even pass the pre-game audition, it doesn't matter, just [Wucheng No. 3 Middle School traveled to the UK to face the robot competition. This name can be lively in the Wucheng education circle.

It's really lively......

Jiang Jiuling and Concubine Zhao and Sun Xiaohu in the group were puzzled at first, how some of the robot chariots that participated in the ring could quickly attack with weapons.

For example, last year's major champion [Dreadnought] was equipped with a javelin weapon that can quickly stab and retract.

The clever Concubine Zhao began to guess that it was driven by motors and gears, and waited for her father to ask a friend to bring the latest scientific magazines from Xiangjiang. The three members of the interest group found out that it was actually a pneumatic weapon that they had never thought of.

A way to release gas through a carbon dioxide cylinder and then pass through a cylinder.

You can't find that kind of small carbon dioxide cylinder, but compressed gas cylinders are not very rare in Wucheng, at least some large factories and hospitals have acetylene cylinders and oxygen cylinders.

Sun Jun has relatives who work in the People's Hospital, and through this relative, he got a discarded two-liter portable oxygen cylinder from the hospital.

Everyone is a senior in high school, and they must understand that oxygen is flammable and explosive.

So the three of them managed to make an adapter air valve, and used a gas pump to inject 0.8 megapascals of air into the empty bottle, and the pressure of the air cylinder was limited, and they found that the air pressure was not enough. The three of them ran to the hospital and filled it with 2 megapascal oxygen cylinders with a pressure of 12 megapascals.

1 megapascal is equal to 10 standard atmospheres.

The inflation pressure of ordinary truck tires is only eight atmospheres, which is 0.8 megapascals.

It stands to reason that the working pressure is usually 12 megapascal oxygen cylinders, and there is no fear of the 2.8 megapascal pressure made up by the three members of the group.

Even if it's a waste oxygen cylinder.

In fact, the three members of the interest group used the gas cylinder as a power to test many times, and repeatedly punched it more than ten times, and after successfully figuring out a set of activation attack system, they were ready to fix the gas cylinder on the base of the chariot.

The fixation method is welding, because only this fixation method can withstand the violent collision of the two vehicles on the field.

Welding, of course, is welding in the empty bottle state.

Everything went well, and when it turned out to be tested, something unexpected happened......

The three members of the team finished the gas cylinder, and when they took out the remote control to test whether the weapon could be successfully activated, the vehicle, named Crimson Arc, exploded instantaneously without warning.
