Anti-Japanese War: Li Yunlong dared to attack Taiyuan

Zhang Dabiao had already brought people to the airport to greet him. When he saw Li Yunlong get off the plane, he immediately went to greet him.

"You've lost a lot of weight, kid!"

Li Yunlong patted Zhang Dabiao and looked at him carefully. He had indeed lost a lot of weight and had dark circles under his eyes.

"I'm not worried about our backbone being damaged, I'm keeping an eye on it every day, not wanting any mistakes!"

"Thanks for your hard work!"

Li Yunlong hugged Zhang Dabiao and then walked towards the cave not far away.

"Commander, we've found the uranium ore you mentioned. There's quite a bit of it here, estimated to be at least 50,000 to 60,000 tons. We've mined over 10,000 tons so far and are storing it in the cave, awaiting your next order."

"More than 10,000 tons? Keep mining and dig up all the uranium here!"

The uranium 235 content in the uranium ore here is not low, but not particularly high either. Researching one Miss Qiu requires about tons of uranium ore, and tons is not enough to make three.

“Is there any problem with the calculation formula?”

"No problem, but there's a number I can't figure out. The heavy snow has blocked the roads, so I can't send anyone to your place."

"show me!"

Thanks to the big guys on Bilibili in his previous life, they explained in detail the methods of growing mushrooms, such as how to rub a mushroom egg by hand, etc., which made Li Yunlong understand the principles and a lot of knowledge that he didn't know in daily life.

Many people would think that making Miss Qiu requires a lot of electricity, and it does.

But why did we build Miss Qiu in Lop Nur? There are no large number of power stations in Lop Nur. Where did our raw materials come from?

The main reason is that we found a method, a method that can save a lot of electricity, which is to use primitive methods to extract uranium 235.

It is to crush the uranium ore, then soak it with dilute sulfuric acid, and then add ammonia water to neutralize it. This can save the process of extracting uranium 235 with a centrifuge and save a lot of electricity.

However, this method also has disadvantages. The process is very dangerous and some accidents may happen if you are not careful. In addition, the purity of the extracted raw materials is still not enough.

Li Yunlong planned to use this primitive method to conduct the first step of the experiment. After having enough raw materials, namely yellow cake, he would purify and transform the uranium, and finally perform isotope separation.

Isotope separation requires a lot of electricity and time, and there is no shortcut to this. However, omitting the centrifuge step also saves Li Yunlong a lot of time.

In addition, there is the chain reaction in Ms. Qiu’s core algorithm. Li Yunlong also knows this formula. The Manhattan Project was troubled by this problem for several months.

This is the most important step for Miss Qiu, and it is also one of the reasons why Miss Qiu is so powerful.

The so-called chain reaction is a neutron bombarding U235, which then splits into three neutrons and continues to bombard U235. The Manhattan Project almost died because the nuclear chain reaction from three to nine stopped and did not continue to fission.

The person who solved this problem was a Chinese female scientist, Ms. Wu Jianxiong (Mr. is a respectful title).

She proposed that after uranium atoms split, xenon gas was produced, which absorbed neutrons and prevented further fission.

Subsequent studies also proved that it was indeed because xenon 135 absorbed neutrons, reducing the number of neutrons and making it impossible to maintain a chain reaction. This also provided theoretical data support for continued research on the Manhattan Project.

Mr. Wu Chien-hsiung (Mr. is a respectful title) is recognized as the mother of mushroom eggs, but because of her identity, she was hidden by the Americans in various materials. Even when the movie "Oppenheimer" was filmed in later generations, Mr. Wu Chien-hsiung was directly concealed and not mentioned at all, deliberately downplaying our contribution in World War II.

In fact, Li Yunlong is now considering whether to bring those big guys back, but considering the current environment and the fact that the national war has not yet ended, he thinks it is better to let them continue to stay with the Americans.

However, Li Yunlong also sent people over in his own way to understand their situation. After the victory, he would quickly find a way to bring them back.

In addition, some big names like Mr. Yu have not yet grown up, and Li Yunlong did not disturb their original trajectory because they have not yet completed their studies. If Li Yunlong brings them back now, it will only bury their talents.

However, in the early spring of next year, Li Yunlong plans to recruit some talents from Southwest Associated University, Southeast University, Tongji University in Lizhuang and other schools.

Li Yunlong was particularly interested in the vegetable jar in Principal Mei's hand, but he didn't know whether Principal Mei was willing to give it to Li Yunlong.

After entering the office, Zhang Dabiao quickly took out a piece of information and handed it to Li Yunlong: "Commander, as you said, various data will be divided into groups of ten. After the calculation, if there is no mistake, we will continue to the next step. If there is an error, we will give it to someone else to calculate again."

"I've calculated this set of numbers over 20 times, and the answers are all different, including this set!"

Zhang Dabiao quickly took out the accumulated documents. After seeing them, Li Yunlong quickly wrote down a series of numbers on these formulas.

"Let them continue to calculate based on this number."

Zhang Dabiao watched Li Yunlong quickly write down the answer and couldn't help but open his mouth wide: "Commander, you can figure it out yourself, why..."

"Why are you asking so many questions? Take me around!"

"Yes!"

Li Yunlong knew the answer, but he didn't know the calculation process. After all, the calculation process of a formula might fill up an entire wall, and Li Yunlong couldn't remember it at all.

The purpose of letting these scientists calculate is to preserve this process so that domestic talents can understand it bit by bit when they study in the future.

Soon, Li Yunlong came to another cave. A group of Russians and Chinese people were sitting in front of tables, busy calculating things.

They all had braziers around them for warmth, and there were various canned foods and some food around them.

Although the environment was a bit crude, food and drink were basically guaranteed, and their lives were much better than when they were in the labor camp.

……

Here are the fourth update, and I still owe six. I don't know much about some of Miss Qiu's stuff, and I looked it up online. If there's anything wrong, please let me know and I'll try to make some changes. After all, I can't make mushroom eggs by hand! ~

Regarding the issue of heavy water, I have studied some information. Heavy water is used as a moderator and seems to be needed in nuclear power plants. Mushroom eggs do not need heavy water and can be replaced with ordinary water. The only difference is that there will be some differences in neutrons.

Finally, I would like to ask for some tickets to urge for updates and some free gifts. If the number of requests for updates exceeds 4,000, I will add another update. There are nearly 30,000 people following the update, so why are there so few requests for updates?

Chapter 493: Thank You for the Gift from the Great Father

"Are any of these Russian researchers planning to flee?"

Li Yunlong asked Zhang Dabiao while observing the surrounding environment.

"Not at the moment, but someone has suggested they need some women..."

"Find them some Outer Mongolian women. Remember to check them for diseases and be careful of infectious diseases. Tell these people that they need to provide something useful in order to get the women, and vodka!"

Li Yunlong planned to keep these Russian engineers for the time being, so generally as long as their requests were not too excessive, Li Yunlong would agree.

"There are some people who want some books."

"Just tell me the title of the book."

"By the way, there's someone who wants to see you!"

Zhang Dabiao patted his head and thought of someone.

"see me?"

"Yes, he said he wanted to see the person in charge here, but he didn't say why. He just asked me to convey it."

Li Yunlong asked curiously, "What's your name?"

Zhang Dabiao took out a piece of paper and read with his head tilted:

"He said his name was Sergei Pavlovich Korolev."

"Ok?"

Li Yunlong was stunned when he heard the name, then asked in surprise: "What's your name?"

Zhang Dabiao read it again: "Sergei Pavlovich Korolev."

Li Yunlong took the note and looked at it carefully. He first looked at the translator's name, then looked at his Russian name, and confirmed that it was the same person he knew. A smile appeared on his face.

"Come on, take me to see it!"

Li Yunlong didn't expect that he had missed a treasure. When Zhang Dabiao submitted the list, Li Yunlong carefully looked over everyone's name and asked them to write down their areas of expertise. However, no one wrote that they were good at aerospace.

Thinking of this, Li Yunlong couldn't help but pat his head. The concept of aerospace is a concept of later generations, and there is no such term now.

This Sergei Pavlovich Korolev is definitely a powerful figure.

How powerful is he? He led the team that developed all of Russia's medium- and long-range missiles, and he was also responsible for the early 212 Project.

Project 212 is an automatic flying winged missile. The Soviet Union's Katyusha and other weapons were developed from this project, and later cruise missiles were also closely related to this project.

And this is just the early scientific research result of Sergei Pavlovich Korolev, who was born in 1907 and is only years old now.

Because of the failure of Project 212, he was accused of joining an anti-Russian organization and was accused of consuming Soviet state funds. He was arrested and imprisoned in 1938 and sentenced to ten years in prison. Later, his sentence was commuted to eight years of forced labor and he was sent to the Kolyma River Gold Mine Concentration Camp in Siberia for supervised labor.

Sergei Pavlovich Korolev's experience has always been used as ironclad evidence to criticize the Big Beard's Great Purge.

Because Sergei Pavlovich Korolev is the chief designer of Russia's launch vehicles, the father of Russia's ballistic missiles, the designer and developer of the P-1 missile, the designer and developer of medium-range ballistic missiles, and the designer and developer of intercontinental missiles.

The P1 missile he developed was Russia's first missile, the P5 missile he developed was Russia's first medium-range ballistic missile, and the P7 he developed was the world's first intercontinental missile, with a range of kilometers and capable of carrying a nuclear warhead with a TNT equivalent of million tons!

In addition to these achievements, he also sent the world's first artificial satellite into space, Gagarin into space, and Tereshkova into space. He also proposed subsequent plans such as the space station.

This person's status in Russia is similar to that of Mr. Qian in China.

Li Yunlong didn't expect that he had picked up such a big treasure.

Or maybe Li Yunlong wanted to slap himself now, because he didn't even know about such a treasure and a mountain of gold.

Thank you, dear Comrade Joseph, thank you, the great and kind father, thank you, the great and just Soviet iron fist, for bringing such a talent to me.

Li Yunlong swore that he was now extremely grateful to Big Beard. He was indeed a kind father. He threw such a powerful figure directly into a labor camp.

At the same time, Li Yunlong couldn't help but sigh, how many sins the bearded man had committed. Korolev was lucky. He survived eight years of life in the labor camp and finally shone brightly in human history.

And more Russian scientists are sleeping forever in the cold land of Siberia.

Li Yunlong felt that if these scientists had not been targeted during the Great Purge, Russia might have already crushed the Americans in technology.

However, since his generous and kind father did not need these scientists to help them build the Russian bear, Li Yunlong reluctantly accepted this gift of fate.

Now Li Yunlong had only one thought, which was that he hoped Korolev would be full of hostility towards the Russians, or even hate them.

In a small cave in the cave, which is usually Zhang Dabiao’s office.

Li Yunlong met the legendary figure of the Russian bear - Sergei Pavlovich Korolev.

At this time, Korolev was wearing a thick military coat, his eye sockets were sunken, he had obvious dark circles, his hair was very messy, and his beard was untidy.

But Li Yunlong had seen his prison photo, and he recognized the man in front of him at a glance as the future father of Russian missiles and aerospace.

Photo of Sergei Pavlovich Korolev in prison.

But now the father of missiles and aerospace is not having a good time, and he looks a little listless.

"Hello, let me introduce myself. My name is Li Yunlong, and I'm a general in China. I was the one who rescued you. I heard you wanted to see me."

Korolev looked at Li Yunlong, then nodded and said, "Yes, I need your help with something."
