A nation's industrial development begins with junior engineers.

The sun rises and sets, time flies.

I used to think I had plenty of time to squander, but in the blink of an eye, those youthful days have gradually faded away in the long river of time.

Every sunset is like a silent period in life, announcing the passing of another day; while every sunrise is like a colon full of hope and the unknown, inspiring people to start anew in a new day, no matter where the world is full of flowers or thorns.

Teacher Zhu's students have arrived, and the key personnel of Factory 723 are also ready to go.

The task of developing the code, jointly undertaken by the First Ministry of Machine Building and the Logistics Department, has been assigned.

It was a large-scale project, yet its name was short. There was no fanfare, only a few bright red documents.

The document is very short:

Code: 301

Project: Cold-rolled pipes

Objective: To achieve cold rolling pressing of metal pipe fittings.

Participants: Secret

……

Steel rolling mill activity center.

"1. Determine the output. 2. Break down the product process. 3. Calculate the production cycle time. 4. Design the workstations. This is the preliminary planning and design of the pulse production line..."

Jiang Xia, holding a large pipe, spoke animatedly about the words on the blackboard.

Because the bearded boss found that the three big bears were doing well in their studies at the steel rolling mill, their recent reports have all been substantial.

They simply sent over the people from Factory 410, which produces aero engines.

Groups 112 and 410 spent half a day conducting research in the engine production workshop. Although they made new discoveries every day, they were still somewhat unclear about some of the methods and approaches.

Why would you have someone push a cart to deliver parts?

Why is the assembly of this part left until last?

Why are workstations divided in this way?

I understand some things, but I'm still completely baffled as to why they're done this way.

As the assigned tasks were distributed, Li Changfu grew impatient with these people who were just "couch potatoes."

The old man who is the chief engineer has recently become quite engrossed in Project 301, and he is deeply dissatisfied with the fact that these people are taking up a lot of Jiangxia's time to answer questions.

After all, the entire 301 is not just a single cold-drawing tube machine.

The old man simply organized a lecture and sent Jiang Xia to give a systematic explanation. He said he wanted them to "know not only what it is, but also why it is so".

After the lecture, get the hell out of here and go practice in production. What are you doing, staying here to celebrate the New Year?

Jiang Xia took the opportunity to introduce the simplified process of the famous "Pulse Production Line".

Regardless of whether it can be implemented in practice, it's better to spread that advanced process concept than to let them rush around blindly.

That's how this era is. In order to achieve the great rejuvenation, everyone from top to bottom is constantly trying and making mistakes.

Since Xiao Jiang has gained an advantage through experience, it's natural that he should share it.

Having made a start, these brilliant minds no longer need to waste time exploring. After all, they are the creators of a "legendary machine," and a little guidance is enough to help them navigate the maze of ideas.

Fun fact: The J-6 was the most produced and exported aircraft in the history of Chinese aviation. It was also the first Chinese fighter jet to enter the international market.

Yes, although more than a hundred of them were sold for only over $4 million, the buyer was Egypt.

Although the large-scale exports were provided to friendly countries as aid, no small sums of money were received.

But others still managed to shoot down more than 20 Taiwanese and American aircraft of various types.

Furthermore, none of them suffered any casualties.

"So many things are urgent; the world turns, time presses on. Ten thousand years is too long, seize the day."

This is the most fitting way to conclude the lecture.

While shaking hands with these distinguished individuals to say goodbye, he also promised to keep in touch through letters.

Jiang Xia clicked his tongue, thinking to himself: Could we go a step further and not ask for photos, but instead have the instructor write "and Comrade Jiang Xia"? These few sentences are such a waste of Lao Guo's time.

Don't blame Xiao Jiang for having this idea. After worshipping the Machine Spirit a couple of days ago, the Machine Spirit was overjoyed, and Xiao Jiang has almost finished assembling all the input/output ports of a transistor computer.

Needless to say, Li Huaide, the "good guy," had already brought over his "Beijing brand" car.

Although it was a vacuum tube, the screen was only 35 centimeters long and the horizontal resolution was just 400 lines, but it was more than enough for scientific calculations and code input.

While it's running, you have to give it a little nudge every now and then, otherwise it won't cooperate.

Thanks to Ma Weihong, who helped me find a teletype machine, I was really fortunate enough to do so because of the 45cc mobility scooter.

Although it's another battle-damaged version, can that really stump Xiao Jiang, who has a cheat code?

BD055 Mechanical Teletype Typewriter.

This name should be familiar to some veterans in the telecommunications sector. Successfully developed in 56, it continued production until the 80s, making it a true evergreen in the telecommunications system.

The output is not very high, only about a thousand units per year.

Moreover, this teletype machine comes with the International Telegraph Code (ITA2), which can display 64 characters through a combination of up to five keys. Although it is inconvenient, it is far better than punched paper tape and those flashing indicator lights.

Although Xiao Jiang really wanted to go home and put all these things together, he had more important things to do right now.

Dig a hole!

This isn't just any ordinary pitfall.

It is an anti-tank trench.

The location for digging the pit is the material storage yard.

Thanks to Big Brother, the famous representative conference statement was published at the end of the year.

The top command issued instructions to carry out militia training, "to overwhelm any enemy that dares to invade with the vast ocean of the masses."

The concept of "everyone being a soldier" is no joke. Regardless of your status, you must undergo systematic training.

The rest of the factories were moved to the team's base for centralized training. Considering that the steel rolling mill had a heavy workload, the higher authorities granted special permission for their training to be conducted in batches and at different times by the security department and veterans from the "Veterans' Home".

As a good young man with impeccable character and integrity, Jiangxia naturally couldn't escape it.

"Anti-tank ditch! 4-5 meters wide at the top, 3-3.5 meters wide at the bottom, and 2-2.4 meters deep, generally trapezoidal in shape! You're all educated people, so I won't say any more!"

"There are three classes here. The class that finishes digging first will get an egg as a reward!"

The three classes were: the technical department from the steel rolling mill, the student team representatives from Teacher Zhu's side, and the key personnel from Factory 723.

Wang Kui stood in front of the crowd, a gentle yet cold smile returning to his lips.

Ha, just a cricket trying to intimidate you.

Jiang Xia turned to look at Li Tiejun, who flexed his biceps.

"The wind rises, the clouds fly, and with one shovelful, dust flies! Watch me!"

"Good bro! The egg you won is yours!"

Jiang Xia patted Tie Jun's steel-like arms, preparing to slip away with Sister Wei Hong to watch his performance.

"Hey you, Tie Jun, you come and dig a single-person bunker. It's a competition, so let's be fair!" The old company commander beckoned to Tie Jun.

Tsk, I knew this would happen!

Jiang Xia pouted helplessly.

Since the last gathering, when Grandma Jiang expressed her concern about her grandson's frail health, Liu Ye has never let him ride in that 210 Jeep again.

It was euphemistically called "polishing Jiangxia's bones and muscles."

The old company commander even went to Jiangxia's office and removed his chair, making him squat in a horse stance whenever he had free time.

"A man needs a strong back! Only when the back and waist are in harmony can he gallop freely!"

Even Li Changfu, who doted on his son, was influenced by his teacher's wife's pillow talk, and not only did he ignore all of this, he also praised it highly...
