Siheyuan: Spring and Autumn

Since Lou Jianye and his wife both agreed, Qin Zheng nodded and said, "Then let me tell you about a war I participated in."

In fact, Qin Zheng often doesn’t like to recall the war, because he can’t help but think of his sacrificed comrades and the cruelty of the battlefield.

However, he would sometimes take the initiative to recall the wars he had participated in, because he wanted to remember what his comrades looked like and did not want to forget them.

Lou Xiao'e was simple-minded and said with great anticipation: "It will definitely be exciting."

Qin Zheng shook his head and said, "War cannot be described as exciting, it can only be described as cruel. Many people do not understand war, so they yearn for it. In the first few days after I went to the battlefield, I vomited twice because of the blood on the battlefield."

"Oh no?"

"It's true. The second one left the deepest impression on me. It was the first time I faced the death of a large number of comrades at close range. When the regiment commander blew the charge, my blood rushed to my head. I jumped out of the trench with my gun in hand and rushed towards the enemy. My speed was so fast that my comrades couldn't keep up. Some comrades said that I was so fast and rushed forward so fast. I didn't feel anything at the time. I just heard the bullets whizzing past my ears."

Lou Xiao'e was shocked: "Ah, this is too dangerous."

"In fact, I was close to the enemy just after I jumped out of the position for 12 meters. My flying knife started to work. By the time I came into contact with the enemy, I had killed enemies with my flying knife."

"Tsk, tsk, that's amazing."

"After I ran out of throwing knives, I started fighting with bayonets with my gun. The first enemy I faced was tall, nearly 1.9 meters tall, with broad shoulders and a strong waist."

Another scream: "Huh?"

"Haha, although he looks strong and powerful, his weakness is obvious. His movements are not flexible and his speed is slow. Before he could draw his bayonet, I stabbed him in the throat."

"Hiss..."

Lou Xiao'e clasped her hands in front of her chest, shaking them back and forth. She was really nervous.

"That is, the blood sprayed on my face and I vomited at that moment."

"If it were me, I would vomit too. It's so disgusting."

Qin Zheng smiled and said, "Before I vomited, I thought, food is so precious, wouldn't it be wasted if I vomited it? I exerted force and vomited on the face of another enemy in front of me."

Lou Xiao'e laughed: "Hahaha...then he has a free meal."

"I was joking when I said we shouldn't waste food. At the time, my stomach did feel a bit uncomfortable, and the enemy was right in front of us, so I didn't control myself."

"Aren't you afraid?"

"I was scared, of course I was scared, especially when I saw someone who was alive fall down at my feet, and I was the next to fall down, so I was always tense. It was because of fear. Do I know what I did at that time?"

"what's up?"

"Recite poetry."

Lou Xiao'e was very surprised. Reciting poems on the battlefield was really unexpected: "Reciting poems? Reciting poems on the battlefield?"

"Yes."

“Do you recite poetry out loud?”

"No, I recited it in a low voice through gritted teeth."

"What poem are you memorizing?"

"Li Bai's "Xia Ke Xing". The Zhao guest's hair is covered with Hu tassels, and the Wu hook is shining with frost and snow. The silver saddle shines on the white horse, and it gallops like a meteor. Kill one person every ten steps, and leave no trace in a thousand miles... When I got here, I had killed all the enemies, and I turned around to look for the enemy again."

"It's so exciting. You're so awesome, Brother Qin Zheng. I admire you so much."

"Thank you for the compliment. By the time I finish memorizing this poem, the battle will be over."

"How many enemies did you kill?"

"The troops have done statistics. In this battle, I killed 38 enemies."

"Hey, 38 people."

Qin Zheng thought she would be scared, but he didn't expect that the girl's next words almost broke his defense. She said: "These invaders deserve to die. They should feel honored to die at the hands of a hero like you!"

As soon as she finished speaking, the three adults in the living room laughed. This Lou Xiao'e was really childish.

Qin Zheng also sighed in his heart, as the daughter of a capitalist, Lou Xiao'e was too well protected. She was very kind by nature, and from beginning to end, her kindness was pure and had no self-interest.

In the TV drama, she chose to go far away for the one she loved, silently giving in the distance without any regrets;

She pursues independence and self-reliance, has distinct emotions, a clear distinction between love and hate, and has a bottom line in doing things.

For those who are kind to her, she will repay them with even the smallest help, and for those who have bullied her, she will always remember them in her heart and will never forget the harm they have done to her. She is a very real person.

However, now, she is just a fourteen-year-old child, still in junior high school, with the innocence of a child!

"Sister Xiao'e, you are still young, and war only exists in your imagination. But I tell you, war has iron rules. For both parties involved in the war, all opportunities are equal. There is no such thing as taking advantage without suffering any loss in the world. Although I killed many enemies on the battlefield, my comrades-in-arms have been decreasing and sacrificing all the time. I am just one of the lucky ones who survived."

"I understand. Thank you, Brother Qin Zheng."

Lou Xiao'e looked serious and seemed touched.

After having lunch at the Lou family, Qin Zheng left the recipe, made an appointment with Lou Jianye to melt the aluminum alloy, and said goodbye and left.

The formula left by Qin Zheng is the 7075 aluminum alloy widely used in the aerospace industry. The United States has already used it to make aircraft in 1943, but it is still blank in China. This aluminum alloy contains zinc and magnesium elements, with zinc as the main element, so it has very good corrosion resistance. Adding a small amount of magnesium alloy can make the material reach very high strength after heat treatment. It also adds copper, chromium and other alloys. This aluminum alloy is known as the best product among aluminum alloys. It has high strength, far superior to any soft steel, and has good mechanical properties and anodic reaction.

Now, of course, he couldn't possibly name the aluminum alloy.

At the Lou family, Qin Zheng did not see Xu Damao's mother. The only servants in the Lou family were a cook and a driver. It seemed that what was said in the TV series was true. Xu's mother worked in the Lou family before liberation. After liberation, the Lou family began to keep a low profile and dismissed some servants.

Qin Zheng returned to school and after gathering with his roommates, Qin Zheng said, "Brothers, I have something good to ask for your help."

Hua Bingchang said, "Tell me what's the matter. No problem. I just want a good meal."

This guy can’t stop talking about food. He is a typical foodie!

"I have compiled a formula for aluminum alloy, and the owner of the Red Star Steel Mill has agreed to make a furnace for me. The time is set for next week. Are you interested? If so, come with me then."

The three of them were shocked at first, and then they all looked happy. This was no small matter. They didn't expect Qin Zheng to have such power.

Hua Bingchang exclaimed: "Holy crap! That's awesome!"

Zou Beichang smiled and said, "Of course I am interested."

As for Qiao Mu, although he didn't say anything, his face was full of excitement and his meaning was obvious.

It was another weekend. At 8 o'clock in the morning, the four of them rode their bikes to the steel rolling mill and, under the guidance of the office staff, went directly into the blast furnace workshop.

Although it is the weekend, all the front-line workers at the steel mill are working overtime today. In fact, working overtime is the norm at the steel mill. The country is newly built and there is a lot of work to be done, so the demand for steel is not small.

After exchanging a few pleasantries with Chairman Lou Jianye and Factory Director Zheng Zichang, the blast furnace was started. Small aluminum blocks and thin sheet waste were added first, followed by the purchased aluminum ingots and large blocks.

As Zheng Zichang shouted "ignite", the flames under the blast furnace immediately lit up, and the temperature was raised to about 750 degrees. After the aluminum material melted into water, it entered the converter workshop and was then cast into billets. After an hour, the smelting was completed. After the aluminum billets were cooled, they were weighed, and 1200 kilograms of pure aluminum were obtained.
