Scholars in the courtyard.

Chapter 1978 I gave it to you at the beginning

"Two methods, let's do it together!"

Zheng Shuangyan said it out loud without thinking.

He was not sure when the engine would be needed, and it would be too time-consuming to deal with them one by one, so it would be better to do two things at once.

By then, it will be safer!
"This, this..."

On the other end, Liu Yuhao began to stutter.

"What this and that, I don't have time to argue with you!"

Director Zheng was furious and spoke rudely.

"This! I want to redo it..."

"This Shicheng Research Institute is still under reconstruction due to the earthquake. Director Zhang said that if we want to complete the mission, we still need to..."

patter
Director Zheng hung up the phone, he was really tired!

"Damn it!"

"Why is it so difficult to do something?"

Zheng Shuangyan slammed the table speechlessly.

Back then, in that poor corner of the northwest, they had nothing to eat or wear, but they still managed to survive.

How come I can't make anything now that I'm back in this city where we have everything I want?

How come this plane's engine is more difficult to fix than a mushroom egg!

Ruffling her sparse hair, Zheng Shuangyan looked up at the photo on the table.

One is of his family.

Another photo is a group photo of them after leaving the Northwest and coming to Sijiucheng.

His eyes lingered on it, then fell on the person next to him.

"Old Ran!"

He spoke softly.

Thinking about the last news I received, it was full of news that the Seventh Ministry of Machine Building also encountered problems.

The rocket exploded before it even took off. It must have been a huge blow!

When I think of this, I feel like we are brothers in distress.

Pick up the phone casually.

After a while, a familiar voice came from inside.

"Old Ran! Where is he?"

"Who? Lao Zheng? Where else can I be? The research base!"

Ran's father's voice came, and there was someone talking in the room, but it didn't seem like it was just one person.

"I want to drink with you! Tell me a place!"

Zheng Shuangyan was feeling depressed and started talking.

"Drinking? What's wrong with you?"

"You can't drink if you're fine!"

"Okay, you, come to our place, the cafeteria is open!"

I really don’t know where Mr. Ran has gone. Besides, he doesn’t have much money on him to go out for dinner!

"You are so stingy!"

"Wait for me, come over immediately!"

After hanging up the phone, Zheng Shuangyan said something to her secretary and got up to go out.

Seventh Machinery Department.

The office was indeed bustling with people.

A group of people are analyzing the last report.

Mr. Qian sat at the top, looking at a photo carefully.

Although the last experiment was not successful.

But the situation on the scene is still worth studying.

Especially for rocket engines, the high temperature generated in such a close-range explosion can effectively demonstrate the high-temperature resistance of the material.

Mr. Qian thought carefully and did not notice Ran's father approaching.

When I put down the magnifying glass, I saw Ran's father standing beside me.

"Wende, look!"

Mr. Qian put the photo in front of him and said, "Look, this photo, here and here!"

Father Ran originally wanted to take a leave, but after listening to what Mr. Qian said, he followed his gaze.

I could see a few pieces of iron vaguely in the corners of the photo.

If you don't use a magnifying glass, you really can't find it!
In an instant, Father Ran put aside the matter of asking for leave and looked at it attentively.

"This is melting!"

After just two glances, Father Ran discovered the problem.

The impact damage caused by the explosion and the high-temperature melting are two different conditions.

The iron sheet in front of me obviously can't withstand the high temperature burning!

"Which part is this?"

Father Ran immediately became alert.

"can not tell."

Mr. Qian nodded, "But. This is a problem."

"We must not bring problems that we can solve on earth to heaven!"

"I understand. I'll go check it out right away!"

Father Ran immediately took the photos and asked two assistants to go to the workshop to find the problem.

As for the idea of ​​asking for leave from Mr. Qian just now, I had already forgotten about it.

Half an hour later.

Zheng Shuangyan arrived at the gate of the Seventh Ministry of Machine Building and told the security guard, but the security guard said that he had not received any news.

As soon as Lao Zheng agreed, his mood immediately became unhappy.

Fortunately, the guard recognized the car of the Third Ministry of Machine Building and called to ask, but it turned out that Ran's father was not there. In the end, it was Mr. Qian who let people in and then opened the door.

Old Zheng, with a look of dissatisfaction on his face, followed the security guard to the door, just in time to see Ran's father carrying two pieces of iron leaves and walking into the office.

In an instant.

The two looked at each other.

Father Ran's heart skipped a beat. Oh no! He had forgotten about this!

More importantly, I forgot to tell the cafeteria.

Looking up at the sky, it seems a little late!
At this time, Zheng Shuangyan, who saw Ran's father, ran up to him in three or two steps and started shouting without thinking.

"Good for you old Ran!"

"I came to drink with you, and you said to go to the cafeteria, which is fine, but you didn't let the guard open the door. What does that mean?"

"The cafeteria doesn't want me to eat either."

"Old Ran, Old Ran."

"I didn't expect that after only being away from the Northwest for a few years, you, a guy with thick eyebrows and big eyes, have also learned how to fight guerrilla warfare..."

"I, I, I made the wrong friends..."

Zheng Shuangyan looked bitter and resentful, but Ran's father was relieved.

This guy is just a big swearer.

At worst, I can go out to a restaurant and pay for it myself.

Well, ask Mr. Qian if he has any money.

"Okay, can't you see I'm busy? Let's go out to eat later!"

Father Ran was still holding two pieces of iron in his hands and was struggling.

Zheng Shuangyan saw it and hurried forward to help.

"You said it! Don't feel bad!"

"I have to satisfy you even though I feel bad!"

Father Ran glanced at Zheng Shuangyan, then asked, "What's wrong with you? It's like you haven't slept for several days."

"This looks even more miserable than when we were in the northwest!"

Hearing what Ran's father said, Zheng Shuangyan sighed helplessly.

"You're right. I've been going crazy these past two days!"

"About the engine?" "Yes!"

After hearing this, Ran's father had no way to comfort her. After all, this thing could not be explained clearly in just a few words.

But it seems that the pressure is not small.

"Did the logistics department say anything about the problem?"

Zheng Shuangyan shook her head, "The specific reason has not been determined, but there is a problem with the engine!"

"What's the problem?"

"Combustion chamber ruptured!"

"The combustion chamber is broken? How could it be broken?"

Father Ran was curious, how could it break without any external force?

"I do not know either!"

Zheng Shuangyan shook her head helplessly.

"By the way, what's going on?"

As he spoke, he weighed the piece of iron in his hand. It looked black, probably because it had been burned by fire.

And like this...

Zheng Shuangyan saw the edge and it looked familiar!

"Something went wrong last time. We are reviewing the situation these days!"

Father Ran was speaking in front.

Then the two of them came to the office building, and Zheng Shuangyan followed them in.

The guard at the door also knew Zheng Shuangyan, and since she was following Director Ran, he did not stop her.

"Leader, we found it!"

When I arrived at the meeting room, people in the room were still busy.

Old Qian had been resting with his eyes closed. When Ran's father came in, Old Qian opened his eyes and looked over.

Seeing Zheng Shuangyan behind him, Mr. Qian was not surprised, but smiled and said, "Looking at you, you don't look like you can't afford to eat!"

Zheng Shuangyan smiled awkwardly when she saw her old boss, "I'm here to see my old boss!"

Old Qian smiled, then looked at what Ran's father was holding, "Did you find it?"

"Found it, it's the engine casing!"

Father Ran put the thing on the ground. Old Qian stood up and squatted in front of it. He reached out and knocked on it, then asked, "Is this made of steel?"

"Well, we didn't expect it to burn from the outside, so the outside of the engine was made of ordinary steel."

Ran's father explained, but Qian shook his head and said, "If you want to do it, do it comprehensively. This kind of saving is not acceptable."

"Yes, I'll have someone replace it with the same alloy to avoid any accidents."

"Yes. Check other places as well. Use the best ones if possible. Although we need to save money, we also need to consider the situation. We should use the best steel on the blade and not ruin the big things for a little profit."

Mr. Qian gave earnest instructions, and Mr. Ran nodded immediately.

He was like this in the past, saving as much as possible and even wanting to do two things with one dollar.

But after this incident, especially after he followed Yang Xiaotao all the way back to Sijiu City, he realized it.

You can't save any money.

"Don't worry, I will personally supervise it."

"Curry has saved a lot of money during this period, and he just needs to find a factory to process it."

After Father Ran finished speaking, Mr. Qian nodded with satisfaction.

"I don't worry about your work."

"Okay, it's getting late today. You take Xiao Zheng to eat. I'm going back too."

As he spoke, Mr. Qian stood up and walked out.

The people in the room were also cleaning up the scene. Ran's father walked up to Zheng Shuangyan and saw that she was still in a daze.

"Old Zheng, come on, I'll treat you to some mutton soup."

Father Ran patted Zheng Shuangyan's shoulder and prepared to go out.

"Wait a minute, wait a minute!"

Zheng Shuangyan frowned and tilted her head in deep thought from time to time, as if she was trying to capture some inspiration.

The next second, Zheng Shuangyan looked up and looked at Father Ran seriously, then asked, "Old Ran, I remember that the aircraft engines you use also have combustion temperature requirements, right?"

"Yeah, you're stupid. You still have to ask this question."

"Hurry up and don't delay people from getting off work."

Ran's father walked out, Zheng Shuangyan hurriedly followed and then pulled Ran's father, "Old Ran, I just heard you talking to the chief about the outer layer being ordinary steel, then, what material do you use inside the engine?"

Father Ran stopped and looked at Zheng Shuangyan suspiciously, "Old Zheng, you are not kidding."

"I'm kidding, look how anxious I am."

"I came here just to drink with you. Why? Because I'm feeling miserable."

"You don't know that I'm an engine when I open my eyes, and I'm still an engine when I close my eyes. I just want to talk to you, I..."

"Stop, stop, stop!"

Father Ran quickly spoke to stop Zheng Shuangyan's chatter, "What do you mean?"

"What is the engine made of?"

"Aren't they all TiG01?"

"What's there to say!"

Father Ran frowned and asked. He remembered that the TiG01 alloy was used by several companies at the beginning.

Their Seventh Ministry of Machine Building used a lot of them, and it is said that the engines made by Yang Xiaotao were also in use.

Oh, by the way, machinery factories use more than them.

"What? What is TiG01?"

Zheng Shuangyan's eyes widened as if she had seen a ghost.

Father Ran frowned even more tightly, because Old Zheng didn't look like he knew about it.

He was not in a hurry to leave, but walked aside and sat down, then opened the drawer and rummaged around for a while before finding a piece of material.

It was they who got the list of TiG01 alloy from the steel mill, and then pushed forward, "Look, isn't this the thing?"

Zheng Shuangyan picked up the document immediately.

The name directly above immediately catches the eye.

TiG01 alloy.

The purchaser was naturally the Seventh Ministry of Machine Building, and the supplier was clearly written as Red Star Steel Plant.

These are not important. What is important is the introduction of TiG01 alloy below.

It has high temperature resistance and meets the requirements of hardness and toughness.
"You guys, is this what you've been using?"

Zheng Shuangyan felt her hands trembling.

I don't know whether to be happy or angry.

"Yes, this is what I use all the time."

"The previous experiments took a lot of time. Fortunately, we discussed it again with the machinery factory."

As Father Ran said this, Zheng Shuangyan opened her eyes wide again, "You, you already had it, why didn't you say so earlier."

"What are you talking about? Didn't I give it to you in the beginning?"

Father Ran snatched the list away directly, but the next second he looked up at Zheng Shuangyan in surprise, "You, you don't, don't know."

Boom~
At this moment, Zheng Shuangyan felt as if her forehead was struck by lightning and she didn't know what to say.

"Old Ran, you, you tell me what's going on!"

Seeing this, Father Ran didn't think much about it and told what he knew.

After a long time, the room fell into an eerie silence.

"That is to say."

"Everyone had a share of this thing at the beginning."

Zheng Shuangyan's eyes turned red. If she told them not to give it to them, they might feel better.

Now, people give it to you, but you don’t use it. Who can you blame?

"No, I have to go back and take a look."

After saying that, Zheng Shuangyan stood up and ran outside. He wanted to go to the warehouse to see if there was any TiG01 alloy.

As for eating and stuff, I don’t even have the heart to think about it.

"Hey, Lao Zheng"

Ran's father ran out quickly, but all he saw was Lao Zheng's running back.
