1959: Carrying the achievement system, she rolled

"Director Song..."

"Lao Qin, Xiao Du, Xiao Wan, you have been busy for more than a year. Now that you finally have some time, you should take a good rest. Health is the most important thing. Only with a healthy body can you make better contributions to scientific research." Director Song said to the three of them with a smile on his face.

He had a bad feeling, so he took the initiative to say good things, and even affectionately called Du Yimeng and Wan Ping "Little Du and Little Wan".

Du Yimeng twitched his lips fiercely. It was Xiao Du again.

However, Wan Ping thought that Director Song's sudden affectionate address to him as "Xiao Wan" must be because he wanted him to continue working hard on scientific research.

He secretly swore in his heart that he would never let Director Song down.

"Director Song, we are not tired. We are always ready to engage in scientific research again and will never let the country and the people down." Wan Ping said in a firm tone.

Director Song: ...

You are not tired, but my hair has just grown out and the child is still too young.

Then he turned his gaze to Qin Chulong. Forget it, this guy also doesn't understand what people say.

Finally, he turned his expectant gaze to Du Yimeng, as he knew that she was a person who understood the ways of the world.

As a result, he saw that she actually lowered her head. At this moment, he felt that his previous bad premonition was right. Perhaps the teacher and student trio were going to do research again.

"Director Song, we want to study tungsten alloy armor-piercing bullets." Qin Chulong said to Director Song with a serious face.

Director Song: It feels like it’s finally here.

"What is this tungsten alloy?" Director Song asked in confusion. He was a soldier and later went to college to study armored technology. How would he know these things?

He had never heard of this alloy and didn't know if it was expensive.

"Student Du, you answer." Qin Chulong directly called on Du Yimeng. He had left in a hurry and had no time to ask, so he didn't know what tungsten alloy was.

"It's an alloy of tungsten and steel." Du Yimeng said concisely. She didn't dare to say more because the more she said, the more mistakes she would make.

Tungsten steel is also called cemented carbide. Its high hardness and strength far exceed those of high carbon alloys. Most importantly, compared with high carbon alloys, it has good toughness, heat resistance, corrosion resistance, and most importantly, wear resistance.

Unfortunately, the current technology does not allow nickel to be produced domestically. Otherwise, the performance of tungsten alloy would be better if this element was added.

That's right. With current technology, tungsten steel is already pretty good. After all, it is known as one of the hardest metals in the world, with a hardness between 8 and 9m, second only to the hardness of diamond.

"What is the difference between this tungsten alloy armor-piercing projectile and our high-carbon alloy armor-piercing projectile?" To be honest, Director Song didn't understand at all and was too embarrassed to ask for explanation again.

If he keeps asking questions after the other person has already explained it, he will seem very uneducated.

He's already wearing glasses, how can he tell others that he doesn't understand anything?

He didn't know what tungsten was, but he knew steel!

The nationwide steel-making campaign was underway, and this was the thing they lacked the least.

"Tungsten alloy armor-piercing bullets can penetrate at least 100 mm of armored steel." Du Yimeng said. As for its advantages and performance, she didn't dare to say more, otherwise how could she explain that she knew it so clearly.

Director Song's eyes lit up. He and Du Yimeng had the same idea. Although it was only 20 mm more than the original armor-piercing projectile, the result was two different concepts.

It’s the difference between actively charging and being charged!

Seeing that the three teachers and students were devoted to research, how could he discourage their enthusiasm? No matter how difficult it was, he was determined to make it happen.

Finally, he sighed silently in his heart, I'm sorry, hair, we'll see each other later.

But he didn’t know that sometimes goodbye means forever.

While Director Song was making his report, the three-person team of teachers and students were also busy making the preliminary preparations.

Du Yimeng directly took on the most difficult preliminary settings. The main reason was that she had the drawings but didn't dare to take them out directly, so she could only pick and choose some of them.

I will add it in little by little during the experiment.

As for fame and fortune, she didn't care, just like Qin Chulong never cared whether his efforts would be rewarded.

Sometimes when people reach a certain level, they no longer care about these material things.

Qin Chulong is like this, as are many scientific researchers, and so is she.

……

Du Yimeng was drawing blueprints in the laboratory that day when the orderly suddenly came to report that someone was looking for her.

She was full of confusion. She had been in the institute for more than a year and no one had ever contacted her.

She walked quickly to the entrance of the institute with confusion. When she saw that the person coming was Tang Jiangbei, her pupils shrank, her body swayed, and she had a bad feeling in her heart.

Seeing Director Song was also here, the uneasiness in my heart became even stronger.

"Comrade Du, come with me quickly..." Tang Jiangbei said anxiously when he saw Du Yimeng.

"Director Song, can I go with him?" Du Yimeng tried hard to suppress her trembling voice. She had already guessed the reason, but she still didn't dare to take it lightly.

Only by staying vigilant can she survive to the end. You know, her value has increased now, and her head is very valuable.

If Director Song agreed to let her go with Tang Jiangbei, it meant that Tang Jiangbei had already negotiated with Director Song, or at least had it reviewed.

Moreover, she is now a soldier and must observe discipline. She cannot leave the institute without Director Song's permission.

"Go ahead, and be careful!" Director Song nodded and said that the higher-ups had already called to negotiate.

Du Yimeng had just gotten into the car when Tang Jiangbei stepped on the accelerator and the jeep quickly moved away from the research institute.

Along the way, her heart was hanging. She wanted to ask how Yu Lang was doing, but she didn't dare to ask, for fear that the result would be unacceptable to her.

She suddenly felt like a coward, not having the courage to confront it directly. She even cowardly thought, perhaps she was mistaken.

He ran all the way to the military field hospital and went through layers of examinations before arriving at the emergency room.

When she saw Yu Yashi, wearing a white coat and a military cap, at the door of the emergency room, all the strength in her body seemed to be drained away, and all her hopes vanished.

As for the other people at the door of the emergency room, she ignored them all.

"Sister, how is Yu Lang?" Du Yimeng asked anxiously.

"The situation is unclear now, but it will definitely be fine." Yu Ya said.

Then her eyes fell on the door of the emergency room. The surgeon in charge was her teacher.

The teacher always acts so arrogant when scolding her. I hope she can continue to act so arrogant this time, otherwise she will really betray her teacher and ancestors.

Yu Ya's words did not comfort Du Yimeng, but instead made her heart rise to her throat.

Several hours have passed since Tang Jiangbei went to pick her up, which means that Yu Lang has been under rescue for at least several hours.

The situation is still unclear, which proves that he must be seriously injured.
