In the team lounge.

Li Zheng pointed at the hand-cranked calculator, his messy hair almost stood up with excitement, and he looked proud: "Brother Wei Dong, I have applied for the calculator for you, can you use it?"

A hand-cranked calculator is not as simple as the electronic computers of later generations. It only requires pressing a few buttons.

It has a cumbersome and rigorous method of use, and most people without professional training would really be unable to use it.

Just like when computers first came out in later generations, people had to sign up for computer training classes to learn daily operations.

However, Li Weidong, who succeeded solely on his own strength, is no ordinary person.

Put your hand on the crank handle and shake it forward and backward for a few times...

With the blessing of thousands of times of experience, I instantly became an expert on hand-operated calculators.

"Come on, let me show you. Niu Meng, give me a question."

Niu Meng said happily: "1220."

Li Weidong: "..."

Good guy, this girl has a junior high school education.

"Pap, tap, tap..."

First turn the up/down button on the right side, then press "1" and "2" on the keyboard from left to right, shake the handle forward in one circle, and the rolling numbers on the bezel in front of the hand-cranked calculator

Jump and the number "12" pops up.

...

.....

With Li Weidong's skillful operation, the gears inside the hand-cranked calculator kept meshing, and the calculation results quickly popped up on the bezel.

"31"

Hey, easy and simple, the pinnacle of this kind of mechanical calculation is magic.

The big guys in the Gobi Desert shook and shook like this to get the big mushrooms out.

The calculator also uses a battery, which only requires half a steamed bun.

...

Li Zheng pursed his lips helplessly. When he came, he had already planned to take advantage of the little driver.

Now I am starting to doubt my life.

He sighed deeply, spread the drawings on the mottled red paint table, and whispered: "Comrade Wei Dong, I issued a military order in front of the chief engineer, and I repeatedly promised that the central support structure would be researched, and the chief engineer approved the note.

..."

"It's you who issued the military order, not me. I'm just a driver.

If you let a driver make an invention, wouldn't you, a ninth-level engineer, blush?" Li Weidong rejected all moral kidnappings.

Li Zheng: "..."

He couldn't understand the driver.

In this day and age, no matter who accepts such a glorious mission, he will be so excited that he screams and beats his chest.

The more positive ones even bit off their fingers and presented them with blood letters.

However, this guy didn't seem to care.

Niu Meng's eyes lit up when he saw it, my master is so handsome!

She happily brought a glass of honey water and gave Li Zheng a sideways look.

"You little comrade, is this your attitude when asking for help?"

"..."

Li Zheng wanted to cry but had no tears.

...

Although his attitude was casual, Li Weidong did his best.

Coupled with the help of a hand-operated calculator, the drawing progressed quickly.

In just one morning, more than half of the data calculations were completed.

At this rate, it may only take three days to complete.

At noon, a passionate announcement came from outside, indicating that it was time to get off work.

Li Weidong stood up unsteadily, shaking his sore neck and sore wrists.

The hand-cranked calculator is very fast, but the inside is full of metal gears, making it too laborious to crank.

"People are like iron rice or steel, let's go eat."

After hearing Li Weidong's instructions, Li Zheng hurriedly packed up the drawings, put them in a drawer, and locked them carefully.

The two of them opened the cotton curtain and stepped into the cold wind.

Niu Meng, who had been lying around all morning, also came out and followed the two of them.

When they arrived at the cafeteria, when they saw Niu Meng approaching, the workers all looked frightened and moved out of the way.

It seems that the rice cook has completely made a name for himself.

"Fifteen steamed buns, six taels of radish vegetables, and three lunch boxes of gruel." Li Weidong squeezed into the crowd without hesitation and said to Silly Zhu, who had dark eyes and kept yawning.

Silly Zhu has become accustomed to the presence of the Big Eater. While scooping up vegetables, he curled his lips and said, "Weizi, why are you so energetic?

Yesterday, after I was driven back by the rain, I slept until about nine o'clock in the morning, and I still have no energy. That old classmate of yours is really good at drinking."

After being reminded by Silly Zhu, Li Weidong realized that his body seemed much better than before.

Since coming into this world, I have never been sick.

What makes him even more excited is that his driving ability seems to have improved a lot, and he can now drive for at least four hours.

Of course, this has never been done in actual combat, so I can’t count on it.

"Maybe it's because I'm younger than you." Li Weidong said casually.

There was too much food, so Silhu thoughtfully found a tray and delivered it to the table.

Putting down the tray, Si Zhu stood there without leaving, waiting to collect the money.

Li Zheng looked at Li Weidong with a suspicious look on his face.

Li Weidong glared at him: "Ninth-level engineer, you have the highest salary among the three of us, and you pay for the food."

"If you have a high salary, you have to pay for food. What's the point?" Li Zheng is not stupid. Such a lot of food costs at least more than one yuan.

Li Weidong smiled at Li Zheng, and then in his speechless gaze, he slowly covered his stomach, the veins in his neck twitched, and he groaned in pain: "Ouch, I have a stomachache. Disciple, help me ask for leave this afternoon."

"Okay, I'll go right away." Niu Meng stood up happily.

Silly Zhu also pretended to be anxious: "Wei Zi, you can't hold on when you're sick. I'll take you to the infirmary right now."

Li Zheng: "..."

He felt that the rolling mill was full of deep malice towards him.

******

Li Weidong lived a very happy life.

In the factory, there are apprentices waiting on you, and there are people who take care of the meals at noon.

In the courtyard, Liu Haizhong and his two sons were busy going up and down.

In order to prepare for the wedding banquet, almost all the residents were mobilized.

Li Weidong and Yu Li hid in the house and played with bumper cars.

Happy days always grow wings and fly away quickly.

Three days later, the last part of the central support structure was finally designed.

Li Zheng took the sketch, and his hands were shaking for a moment.

It's not easy, it's really not easy. I, Li Zheng, finally won!

"Why, you can't bear to leave and want to stay here for a while?" Li Weidong asked.

"...No, I'll leave right away." Li Zheng touched his shriveled pocket, hugged the drawings and rushed out of the lounge without looking back.

Niu Meng whispered from the side: "Master, just let him go, I haven't had enough fun yet!"

"...." Li Weidong.

******

It was already after lunch when Li Zheng left. The fleet seemed to have a lot of transportation tasks today, and all the trucks in the parking lot set off.

Only Li Weidong's truck is still parked there.
