When he returned home, Jiang Jiuling deliberately looked in the mirror.

The reaction of the old principal of No. 1 Middle School made Jiang Jiuling wonder if he had degraded even the extraordinary temperament on his body after he became younger?

In the past, Jiang Jiuling was looking for someone to do things, even if it was the first time they met without intersection, the other party would be polite and warm when they saw Jiang Jiuling.

Because Jiang Jiuling gives people a sense of momentum in their hands.

After looking left and right for a long time, Jiang Jiuling found that his temperament had indeed degraded a little, and he had become beautiful.

But there is no way, I am only seventeen years old now, and the words "Little Fresh Meat" are almost written on my angular face. At this age, it's okay to be handsome, and it's really embarrassing to want to show some extraordinary momentum to make people believe in themselves.

Touching the bridge of his tall nose, Jiang Jiuling thought to himself that age was a hard injury.

Then speak with strength.

People have become younger, but the knowledge they have in their minds has not been lost at all. In Jiang Jiuling's view, going to No. 1 Middle School is already ironclad, as long as the "grades" are taken.

This result is not Jiang Jiuling's previous report card.

His previous grades also hovered around the top ten in the class, and whether he could be admitted to the undergraduate program depended on luck, and it was obviously unrealistic to expect this result to impress the principal of No. 1 Middle School.

This achievement requires Jiang Jiuling's actions to do.

This is a world where the Sacred Industrial Code rules over scientific and technological civilization, and Jiang Jiuling still can't feel the changes that the Code has caused to his life and society, because he is only seventeen years old now, and he is too low.

In the book "The Extraordinary Road from Ordinary Worker to Steel Milling Foreman", the author Su Yi has used his own personal experience to describe the code and the life changes brought about by becoming a title engineer.

The steel milling foreman is only the second-stage title given by the code, if you use the eighth-level fitter that Jiang Jiuling once understood, or the later title rating.

The steel milling foreman can only be regarded as a step forward before the Long March, and it can be regarded as the stage when they just knew each other's names before talking about boyfriend and girlfriend.

In the eyes of other titles, the steel milling foreman may only be regarded as a young pole just getting started.

But in ordinary society, the title of steel milling foreman can only be described as dazzling.

The author Su Yi boasted in the book that after he won the title of steel milling foreman, love and career quickly ushered in a double harvest. Not only was he quickly promoted to the director of the production plant in the factory, but even Hudan University, which he was talking about, sent him a special invitation letter and invited him to come to the school to listen to the gold plating.

Then at the age of twenty-seven or eighteen, he received more than a dozen love letters at school alone.

Jiang Jiuling thinks that he is suspected of bragging in the love letter, but whether he brags it or not, this shows that as long as he can become the person who is awarded the title by the code, he can easily struggle for N years less than others.

Therefore, Jiang Jiuling only needs to let the old principal know that he has the potential to become a titler, and he will be able to do it soon.

Then go to No. 1 Middle School to study for free.

Thinking of this, Jiang Jiuling pushed open another door in the living room.

Jiang Jiuling's house has three tiled houses, a kitchen and bathroom, and a yard.

There are bedrooms on the left and right sides of the living room, Jiang Jiuling lives in one, and the other room used to be his grandfather's residence, but then it was empty, and Jiang Jiuling put some things that were not commonly used.

There was an old-fashioned wooden cabinet inside, and in the wooden cabinet were some metal parts and tools that Jiang Jiuling had accumulated in the past.

During the period when the Crimson Arc Interest Group was in full swing to build the robot chariot, Jiang Jiuling, who had the strongest hands-on ability, had been responsible for the main body welding and structural modification of the robot chariot.

In order to build this chariot, the three friends did not know how many times they went to the metal scrap yard to find those useful scrap machine parts.

Some of the parts that were found were used in the chariot, and those that were not used were taken home by Jiang Jiuling.

Originally, these things were Jiang Jiuling's favorite toys, but since that accident, they have been put in the cabinet by Jiang Jiuling and have been eaten to this day.

Jiang Jiuling couldn't remember what things were put in the original, but after the wooden cabinet was opened, the contents made Jiang Jiuling a little disappointed.

The wooden cabinet is divided into three layers, the first layer is a few tools, and the only one that can be considered advanced is an electric mill. The second layer is some motors and motor gears, ranging from the smallest 130 motor for 4WD vehicles, to the larger 460 motor, to the asynchronous freezer motor, which may have been removed from the refrigerator.

The size of the motor is only five or six, and the value is less than a hundred.

The third layer is even more valuable, which are ordinary bearings, pulleys, valves, transmission rods and the like.

What Jiang Jiuling really wants to find is electronic product parts, if you want to make any achievements to convince others, there is no doubt that electronic products are the easiest and best to do. But now the things in my collection are just the most ordinary mechanical parts.

It's all pediatric stuff.

Jiang Jiuling couldn't help but smile dumbly, and began to recall what he was playing when he was seventeen years old before the time travel.

At the age of seventeen, the four-wheel drive car has been reduced to an ornament, and a pile of four-wheel drive race trophies are locked in a display case.

The simple four-wheel drive vehicle and remote-controlled car structure are no longer enough to meet their own pursuits, even if it is a hand-wound motor.

At that time, I began to become obsessed with model airplanes.

Starting with a simple shell painting sticker, I ended up mixing Tamiya model paint and outlining the fighter paints of various countries with an airbrush.

This was followed by a hands-on group of helicopter models and their own modifications, to the engines, gyroscopes, starters, igniters, and flight control boards.

Jiang Jiuling still remembers the eyes of the senior high school mathematics teacher when he saw himself in class, using manuscript paper to calculate the flight control algorithm of the 470L helicopter, and the formulas of Euler angle, rotation matrix, four elements, and angular velocity.

Of course, there are natural reasons for the limitations of age and family conditions, but if you don't have a smart mind and the spirit of studying hard, no matter how good your family is, what is the use.

In the community where Jiang Jiuling lives, the conditions of every family are not bad. As a result, those peers are not the little stars in their eyes who look at Jiang Jiuling with envy?

Ordinary mechanical parts, just ordinary mechanical parts.

With his own ability, even if it is a pair of broken copper and iron, Jiang Jiuling is confident that he can turn them into treasures.

"Huh?" Just as Jiang Jiuling was sorting out the parts in the cabinet, there was a knock on the door outside the courtyard.

Jiang Jiuling thought it was Zhang Ying, and she didn't have any friends except herself. As a result, when I wiped the rust on my hands and opened the door, I found that the person who came was an experimenter and a middle-aged man dressed as a worker I had seen in the Wucheng Industrial Committee a few days ago.

This experimenter's name is Xie Dong, and when Jiang Jiuling demonstrated the glass fiber drawing technology, he was the most active on the side.

Xie Dong was not very old, he squeezed his eyes at Jiang Jiuling, and said with a smile: "I didn't expect it to be me, right?"

"I really didn't expect it. Jiang Jiuling pulled the door in a little and motioned for him to come in as a guest, "Did you encounter any problems with the article to be published?"

"What problems can I encounter when I post an article?" the other party waved his hand arrogantly, "I have sent you a baby." ”

"Baby~ What baby?"

"Your baby, of course. Xie Dong stepped back, and there was a tricycle parked in the box behind him. When Jiang Jiuling saw the items pulled in the tricycle, his eyes were as firmly fixed as cement.

It was a red, beetle-like metal shell.

The words "Crimson Arc" are firmly attached to the surface of the metal shell like a charm, and under the shell, you can faintly see the four wheels and the anti-collision beams installed on both sides of the frame.

This strangely shaped chariot is in strong contrast with the human-powered tricycle that carries it.
