Scholars in the courtyard

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

Zheng Shuangyan said it without thinking.

He wasn't sure when the engines would be used, and doing them one by one would delay things, so he might as well attack them both ways.

When the time comes, you can, just be safe!

"This, this..."

On the other end, Liu Yuhao stuttered.

"I don't have time to argue with you about this or that!"

Director Zheng was very angry and spoke rudely.

"This! I want to do it again..."

"This Shicheng Research Institute is still being rebuilt due to the earthquake. Director Zhang said that if we want to complete the task, we still have to..."

snap

Director Zheng pressed the phone, feeling really tired!

"Damn it!"

"Why is it so hard to do something!"

Zheng Shuangyan patted the table speechlessly.

I remember that in that poor corner of the northwest, they had nothing to eat, nothing to wear, and they survived.

Why can't I get everything I want when I come back to the Forty-Nine Cities?

Why is this plane's engine more difficult to fix than a mushroom egg?

Rubbing her thin hair, Zheng Shuangyan looked up at the photos on the table.

One is of his family.

The other one is a group photo of them coming to Sijiu City after leaving Northwest.

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

"Lao Ran!"

He spoke softly.

Thinking of the news I received last time, the Seventh Machinery Department also encountered problems.

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

Thinking of this, I feel like we are brothers in the same boat.

Picking up the phone casually.

After a while, a familiar voice came from inside.

"Lao Ran! Where are you?"

"Who? Lao Zheng? Where else can I be, at the research base!"

Ran's father's voice came, and there was someone talking in the room, and it didn't look like he was alone.

"Looking for a drink with you! Let's find a place!"

Zheng Shuangyan felt depressed and started talking.

"Drinking? What's wrong with you?"

"You can't drink if you have nothing to do!"

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

Ran's father really didn't know where he was. Besides, he didn't have much money on him when he went out to eat!

"You are so stingy!"

"Wait for me, come over immediately!"

After hanging up the phone, Zheng Shuangyan told her secretary to get up and go out.

Seventh Machinery Department.

The office was really buzzing with people.

A group of people are analyzing the last report.

Mr. Qian sat at the top and looked at a photo carefully.

Although the last experiment was not successful.

But the situation at the scene still has research significance.

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

Qian Lao thought carefully and didn't notice Ran's father approaching.

When he put down the magnifying glass, he saw Ran's father standing aside.

"Wende, look!"

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

Ran's father originally wanted to take a leave for a while. He listened to Mr. Qian's words and followed his eyes.

I saw a few pieces of iron faintly visible in the corners of the photo.

If you didn't use a magnifying glass to look at it, you really wouldn't be able to spot it!

In an instant, Ran's father put aside the matter of asking for leave and looked attentively.

"This is melting!"

After just two glances, Ran's father discovered the problem.

Impact damage caused by explosion and high temperature melting are two different states.

The iron piece in front of me obviously cannot withstand the high temperature!

"What part is this?"

Ran's father immediately became alert.

"I can't tell."

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

"The problems we can solve on earth must not be taken to heaven!"

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

Ran's father immediately took the photo and called two assistants to go to the workshop to find the problem.

As for the matter of asking Mr. Qian for leave just now, he had already forgotten it.

Half an hour later.

Zheng Shuangyan came to the gate of the Seventh Machinery Department and told the security guard, but the security guard said that he had not received any news.

Lao Zheng agreed and immediately felt bad.

Fortunately, the guard recognized the car from the Three Machinery Department and called to ask. But Ran's father was not there. In the end, Mr. Qian let him in and then opened the door.

Lao Zheng looked dissatisfied and followed the guard to the door, just in time to see Ran's father walking into the office carrying two iron leaves.

In an instant.

The two looked at each other.

Ran's father's heart skipped a beat, he had forgotten about this!

More importantly, I forgot to tell the canteen.

Looking up at the sky, it seems a little late!

At this time, Zheng Shuangyan, who saw Ran's father, ran forward in a few steps and shouted without thinking.

"Good old Ran!"

"I came to you for a drink, but you said I could just go to the cafeteria and not let the guard open the door. What do you mean?"

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

"Lao Ran, Lao Ran."

"I didn't expect that after just a few years after leaving the northwest, a guy like you with thick eyebrows and big eyes would learn to fight guerrillas..."

"I, I, I made careless friends, I..."

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

This guy just cursed a lot.

At worst, go out to a restaurant and bleed some yourself.

Well, I asked Mr. Qian if he had any money.

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

Ran's father was still holding two pieces of iron in his hands and was struggling.

Zheng Shuangyan saw it and quickly stepped forward to help.

"This is what you said! Don't feel bad!"

"I feel bad but I have to satisfy you!"

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

"Looking like this, I'm even more embarrassed than when I was in the northwest!"

Hearing Ran's father say this, Zheng Shuangyan sighed helplessly.

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

"What about the engine?"

"right!"

Ran's father couldn't comfort him after hearing this. After all, this thing cannot be explained clearly in one or two sentences.

But it seems that there must be a lot of pressure.

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

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

"What's the problem?"

"Combustion chamber ruptured!"

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

Ran's father was curious, how could it be broken if there was no external force?

"I don't know either!"

Zheng Shuangyan shook her head helplessly.

"By the way, what's going on with you guys?"

As he said this, he weighed the iron piece in his hand. It looked like it was dark and must have been burned by fire.

And like this...

Zheng Shuangyan saw the edge, and it looked familiar!

"Didn't something happen last time? We are doing a review these days!"

Ran's father said from the front.

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

The guard at the door also knew Zheng Shuangyan, and following Director Ran, he did not stop him.

"Leader, found it!"

When we came to the conference room, people in the room were still busy.

Mr. Qian was already closing his eyes to rest. As Father Ran came in, Mr. Qian opened his eyes and looked over.

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

Zheng Shuangyan also smiled awkwardly when she saw her old boss, "That's not it. I'm not here to see the old leader!"

Qian Lao smiled, then looked at the thing in Father Ran's hand, "Found it?"

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

Ran's father put the things on the ground. Mr. Qian stood up, squatted down in front of him, reached out and knocked, and then asked, "Is this made of steel?"

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

Ran's father explained on the side, but Qian Lao shook his head after hearing this, "If you want to do it, do it comprehensively. This kind of saving is not necessary."

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

"Yes. There are other places to check and check, and use the ones that can be used. Although we have to save, we must also consider the situation. Good steel is used on the blade, and we can't ruin big things for small profits."

Mr. Qian taught earnestly, and Father Ran nodded immediately.

He used to be like this, saving everything he could, wishing he could save one dollar to do two things.

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

There is no way to save money.

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

"Curry has saved a lot during this period. He can just find a factory to process it."

After Father Ran finished speaking, Mr. Qian nodded happily.

"I can rest assured that you will do the work."

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

While talking, Mr. Qian got up and walked out.

People in the room were also cleaning up the scene. Ran's father walked up to Zheng Shuangyan and looked at him still in a daze.

"Old Zheng, let's go, I'll treat you to mutton soup."

Ran's father patted Zheng Shuangyan on the shoulder and prepared to walk out.

"Wait a minute, wait a minute!"

Zheng Shuangyan frowned and tilted her head from time to time, as if trying to capture some inspiration.

The next second, Zheng Shuangyan raised her head and looked at Ran's father seriously, and then asked, "Old Ran, I remember that the aeroengine you use also has combustion temperature requirements."

"Yes, you are stupid, you still have to ask this question."

"Let's go quickly, don't delay others from getting off work."

Ran's father walked out, and Zheng Shuangyan quickly followed and pulled Ran's father, "Old Ran, I just heard what you told the chief. The outer layer is made of ordinary steel. So, what material is used in your engine?"

Father Ran stopped and looked at Zheng Shuangyan suspiciously, "Old Zheng, are you kidding me?"

"Am I kidding? Look at how anxious I am."

"I came here to have a drink with you. Why? Because I feel miserable."

"You don't know that when I open my eyes, I'm still a motor, and when I close my eyes, I'm still a motor. I just want to nag you, me"

"Stop, stop, stop!"

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

"The material of the engine?"

"Aren't they all TiG01?"

"What's there to say!"

Ran's father frowned and asked, but he remembered that this TiG01 alloy was used by several companies together.

Their Seventh Machinery Department uses a lot of them, and it is said that the engines made by Yang Xiaotao are also used.

Oh, by the way, the machine shop uses more than them.

"What? What is TiG01?"

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

Ran's father frowned even more tightly, because Lao Zheng didn't look like he knew.

He didn't rush out, but sat aside, then opened the drawer and rummaged around for a while before finding a piece of material.

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

Zheng Shuangyan immediately picked up the document.

The name at the top immediately caught his eye.

TiG01 alloy.

The purchaser was naturally the Seventh Ministry of Machine Building, and the supplier clearly stated that it was Red Star Steel Plant.

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

It has the characteristics of high temperature resistance and meets the requirements of hardness and toughness.

"You, you have been using this all the time?"

Zheng Shuangyan felt his hands trembling.

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

"Yes, I have been using this all the time."

"It took a lot of time for the previous experiments, but fortunately I discussed it again with the machinery factory."

As Ran's father said this, Zheng Shuangyan opened her eyes again, "You, you already had it, why didn't you tell me earlier."

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

Ran's father took the list directly, but the next second he looked up at Zheng Shuangyan in surprise, "You, you don't, don't know it."

Boom~

At this moment, Zheng Shuangyan felt like his forehead was struck by lightning, and he didn't know what to say.

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

Seeing this, Ran's father didn't think much and told what he knew.

For a long time, the room fell into a strange silence.

"In other words."

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

Zheng Shuangyan's eyes were red. If she said she didn't give it to them, they would feel better if they didn't know about it.

Now, people have given it to you, but you don't use it. Who can you blame?

"No, I have to go back and check."

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

As for eating, he had no time to think about it.

"Hey, Old Zheng"

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