Siheyuan starts from a good life

"Grandma, you didn't promise them to give me a blind date, did you?" Jiang Yan asked Grandma Lu nervously at the dinner table.

"Of course not! Grandson, you want me to promise them!" Grandma Lu asked Jiang Yan after taking a sip of noodle soup, with a hint of ridicule in her tone.

"Of course not!"

"Then let's get married. Old lady, I'm not stupid. Who are the people they introduced? Are they worthy of my eldest grandson? My eldest grandson is a college student, so at least I need to find someone similar to him, right?"

"Now there are new people, new things, and a new country. The country does not advocate free love. I believe in my grandson's vision."

After hearing Grandma Lu's words, Jiang Yan finally felt relieved. He was really afraid that the old lady would mess up the story.

How old are you? According to future generations, you are still a high school student at your age! He doesn't want to get married so early.

But if you have an eye for it, that's a different matter.

But today, several aunts reminded Jiang Yan that Jia Dongxu was two years older than him and had reached the age to propose marriage. Could it be that Qin Huairu was coming to the courtyard.

Thinking of this, Jiang Yan couldn't sit still.

He knew He Yuzhu very well. This guy was just a show-off, and he was also a guy with a thief's heart but no courage.

Thinking of this, Jiang Yan's eyes rolled. Otherwise, take He Yuzhu to intercept Hu Qin Huairu.

It is better to follow He Yuzhu than to follow Jia Dongxu. The Jia family is good now, but after Jia Dongxu leaves, it will be a fire pit.

As for whether to save Jia Dongxu or not, it all depends on fate. If he does, he will definitely save him. If he doesn't, then he can only apologize.

He can't just go to Jia Dongxu and say that in the future you will be crushed to death by machines and your wife will become a widow.

If he really said that, he would probably be regarded as crazy.

"By the way, grandma, Uncle Xu will treat me to dinner tonight, so I won't eat at home. I'll prepare a meal for you then." After dinner, Jiang Yan put away the bowl and chopsticks and said to grandma sitting next to him. Mouth.

"No, grandma, I will make it myself. You can eat yours and don't worry about us. I will eat it with Yu Yu when the time comes."

At this moment, Xu Damao walked in carrying two skewers of mushrooms, a chicken, a fish and some meat dishes. He heard what Jiang Yan and grandma said and spoke.

"Boss, tell grandma to stop doing it. When the time comes, just let Zhu Zhu do more. It's a big deal."

"Okay, that's it. It's not Damao. Didn't I say that I would go to your place to eat tonight? Why did you bring the food over?"

Hearing Jiang Yan's words, Xu Damao laughed and said a little embarrassedly: "It's not that the place at my house is small, it's a bit crowded when sitting down. Your place is big, and it will feel better to eat in the yard."

"Also, boss, I know that you have the best seasonings here. I heard Zhu Zhu say that there are some things that he can't even get."

What Xu Damao said is of course the truth. The seasonings people eat in these days are oil, salt, soy sauce and vinegar, and there are far less seasonings than those in later generations.

Jiang Yan was naturally not used to eating, so he used the excuse that he had a secret recipe to bring out a lot of seasonings.

"Okay! It's fine here, but you're bleeding profusely today! I guess you've used all your meat tickets in the past two months!"

"I don't know about this. This is something my dad asked me to bring when I got home. If it's okay, just eat it."

In the evening, it was still He Yuzhu and Xiao Liuzi who were the chefs. Their skills were fully utilized, and the food they cooked was delicious, delicious and delicious.

Seeing that people had almost finished eating, Xu Fugui picked up the wine glass and gave it to Jiang Yan to touch, and said, "Xiao Yan, Damao is getting older and it's time to be independent. Your aunt and I are going to move back to the old house. Please take more care of Mao here, and thank you first for your uncle Xu here."

"Uncle Xu, you are serious. Damao and Zhuzi are both my brothers. Don't worry, I will take care of what needs to be done. But when the time comes, Uncle Xu, you can't feel bad."

"Don't worry! I'll beat you if you need to, as long as you can't kill him."

Jiang Yan looked at Xu Damao and laughed after hearing Xu Fugui's words.

At this time, Xu Damao was having a drink with He Yuzhu and did not hear the conversation between Jiang Yan and his father. However, when Jiang Yan looked at his climate, he shuddered involuntarily.

From this day on, Xu Damao joined Jiang Yan and the others. They went to work and off work together, and they also rode Jiang Yan's bicycle in turns.

When everyone in the steel rolling mill learned about the relationship between Xu Damao and Jiang Yan, they naturally received a lot of care in the mill.

On this day, Jiang Yan was calculating 7075 aluminum alloy in his office.

This aluminum alloy is a commonly used alloy in the 7 series aluminum alloy.

It belongs to the Al-Zn-Mg-Cu series superduralumin. This alloy is an ultra-high-strength deformed aluminum alloy that has been used in the aircraft manufacturing industry in the late 20s and is still widely used in the aviation industry.

This alloy is a high strength heat treatable alloy. Good mechanical properties. Good usability. Easy to process and good wear resistance.

7075 materials generally add a small amount of copper, chromium and other alloys. Among them, 7075-aluminum alloy is particularly top-grade.

Although it appeared relatively early, it is not currently produced in China.

The reason why Jiang Yan took out this alloy was to prepare for the country's subsequent introduction of the MG-15 aircraft.

This aluminum alloy is not only suitable for the aerospace industry, it is also suitable for trucks, tower buildings, ships, pipelines and other buildings that require strength. It can also be regarded as a tiger balm product.

Although the formula of this alloy is a confidential thing now, in Jiang Yan's time, the formula of this alloy could be found online.

Jiang Yan's factory had produced a batch of this alloy, and Jiang Yanqi was quite familiar with it.

It's just that the purity of the production equipment and other metals added in later generations cannot be compared in this era.

Therefore, Jiang Yan could only recalculate the optimal proportions of the formula based on the current situation, but with the formulas from previous lives, it was not difficult to calculate them.

At the stall where Jiang Yan was concentrating on his calculations, the phone on his desk rang.

Jiang Yan frowned when he heard the phone ringing. However, he put down the pen and picked up the phone.

"I'm Jiang Yan, what can I do?"

At this time, I heard someone say on the phone: "Hello, Chief Jiang, I am Xiao Li from the Security Department. Two employees from the 49 City Public Security Machinery Maintenance Center are here to see you. Their names are Zhang Yong and Wang Dabao. "

Hearing the words about guarding Kemen Gang, Jiang Yan remembered that it seemed that these two people were still Jiang Yan's apprentices, and they didn't know what he had come to see him for today.

Thinking of this, Jiang Yan said into the phone: "Let them in!"

After hanging up the phone, Jiang Yan directly called the guard room on the second floor and told them the work units and names of the two people coming over.

Now Jiang Yan is considered the chief engineer of the steel rolling mill, and almost all technical information and drawings in the mill are here.

For the sake of confidentiality, Director Zhang specially arranged a guard room on the second floor.

Not to mention people from outside, people from the technical department could not enter Jiang Yan's office without his permission.

Even the person who often cleans Jiang Yan's house has undergone strict scrutiny.
