July 6, 1933. At 3 o'clock in the morning on this day, the Battle of Amursk broke out! 150,000 White Russian troops, supported by 500 artillery pieces and more than 200 aircraft of the German Condor Legion, as well as more than 10 Japanese gunboats, launched a full-front onslaught against the 100,000 Soviet Red Army defending Central Amursk! At the same time, the Chinese and Japanese intervention forces also launched a diversionary attack on the Ussuriysk defense line, which the Soviet Red Army had painstakingly managed, and for a time the entire Far Eastern battlefield was in a white-hot state!

And at this time, the vast majority of China seems to be indifferent to this war that is taking place on the doorstep, and the whole country has now entered a period of steady development. The Soviet Union was in a civil war, Japan had been defeated, the other powers seemed to have good relations with China, and there were two "strong" allies in Europe, Germany and Poland, and even the economy was not affected by the Great Depression and was in a period of vigorous development. It seems that the turbulent days of this country are over, and everyone just needs to live a good life and watch the country flourish under the strong leadership of a reactionary.

In the small cafeteria of Wuhan Sino-German United University of Technology, it is like a dinner party, Chinese dim sum, Western dishes, and a variety of fruits and cold dishes. Female soldiers dressed in Wehrmacht uniforms carry trays of fine wine and beverages on them, and walk around the restaurant, filling their glasses when they see them empty. Most of the guests who came to the dinner were from the U Engineering Committee and the Sun Yat-sen Academy of Sciences, and most of these people were foreigners, only a few were Oriental faces, but they were fluent in German or English! And they all looked at the foreign devils in the restaurant with adoring eyes...... It's really a bit of a suspicion of admiring foreign flattery! At this time, the guests all stood casually, talking and laughing with each other in low voices. But everywhere the talk is about something called uranium! And Luo Yaoguo, chief of the General Staff of the National Defense Forces, was only wearing a silk robe at this time. Natalie, who was holding the bright and radiant Natalie, walked around the restaurant, stretched out her ears, and listened with great interest to what the great scientists wanted to do with uranium-235.

"Why would we spend so much money on such a boring project as how to separate uranium-235? Is it just to win a Nobel Prize? Professor Wei, why don't we put our money into something more meaningful? For example, some special alloys, those that are resistant to high temperature, corrosion, fatigue, and lightweight, our aeronautical research institute is now in urgent need of some special alloys that can be used to strengthen the engine structure and fuselage structure, and you have many world-class scientists in the engineering committee. Can you get them to ...... direction of their research?"

Oh, this is Wang Zhu from the Institute of Aeronautics, who is also an academician of the Sun Yat-sen Research Institute, so he was also invited to this dinner...... Isn't it time to start the strategic bomber project? Otherwise, what will be used to drop the atomic bomb in the future? Luo Yaoguo took a sip of champagne and thought with a smile.

"I think it is possible to separate a stream of ionions from uranium in a magnetic field to produce uranium-235; This method is the current method used to separate uranium-235 in the laboratory, and the mass spectrometer we use today does just that. I want to build a giant mass spectrometer to get a sufficient amount of uranium-235, something that no one has done before -- there are a lot of special things to be made, and the key component is the giant electromagnet, which we want to use to maintain an unchanging magnetic field. The slightest change in voltage can erase the tiny difference between uranium-238 and uranium-235. ”

"I think the best way to separate uranium isotopes is to first turn them into a gaseous compound and then use a metal diaphragm with a microporous structure. Micropores can restrict ordinary airflow and allow diffusion flow to pass through. This makes it possible to take advantage of the difference in mass for isotope separation. The key to this method is to create a stable gaseous compound of uranium, in addition to finding a suitable metal diaphragm...... After all, it is easy to make stable gaseous compounds of uranium, and now there is a laboratory method, that is, hydrogen fluoride is used to react with uranium dioxide, and then uranium tetrafluoride can be obtained, and then uranium tetrafluoride is reacted with fluorine. It is possible to obtain uranium hexafluoride, a gaseous compound of uranium. However, the manufacture of metal diaphragms is a technical bottleneck, and it is probably impossible to break through in the short term by relying on China's scientific research and industrial technology alone, so we should seek help from German or American companies...... In addition, if an industrial uranium isotope separation plant is to be built, it will probably need to involve large German and American companies, as well as a large-scale power plant to power the isotope separation plant......"

Well. It was the Hungarian Jewish scientist Leo. Professor Silard and the Austrian Jewish scientist Otto. Robert. Professor Frisch discusses methods for separating uranium isotopes. Hearing the conversation between these two people, Luo Yaoguo couldn't help but stop. Silard's method should be the electromagnetic separation method, while Frisch's method should be the gas diffusion method. These two methods are also the main methods for discovering and isolating isotopes today, and they are also the main methods used in the Manhattan Project historically...... If I remember correctly, the gas diffusion method should be more suitable for the mass production of uranium-235 than the electromagnetic method! And obtaining a sufficient amount of uranium-235 is the key element in the production of an atomic bomb, and it is also the most difficult hurdle!

Relying on China's current industrial base and scientific research strength, it is almost an impossible task to develop and produce a gas diffusion machine! The only way to do this is to use the scientific and industrial strength of Germany and the United States to design and manufacture a gas diffusion machine...... Good thing at the moment Otto. Hahn and Lizzie. Meitner has not yet discovered the phenomenon of nuclear fission. This was discovered in 1939, and if this is still the case in this space-time, China would have five to six years to build a uranium isotope separation plant. After all, before the discovery of nuclear fission, the United States and Germany should not realize the strategic value of uranium-235, and they will not strictly control the equipment and technology that may be used to separate uranium-235!

Of course, there is also a problem with this, that is, Germany and the United States, once they learn about the nuclear fission phenomenon, can also use the methods that China has found to create more gas diffusers for the large-scale production of uranium-235...... That is, the appearance of nuclear weapons will be earlier than in history! It will even come at the height of the Second World War!

But Luo Yaoguo now feels that he has no choice, because before the nuclear fission phenomenon was discovered. Invest a lot of resources in uranium isotope separation. Obtaining relevant technology and equipment from Germany and the United States is the only shortcut for China to possess nuclear weapons at the same time as the United States and Germany! And it must be done, because after the world enters the nuclear age, the only way to keep the world empire that has been in place is to have nuclear weapons! Otherwise, no matter how many victories you grab, you will inevitably end up in nothing.

"Text! This is really a ridiculous plan, a mega-thermal power station, a plant to process uranium ore into uranium dioxide...... Also build a plant to separate isotopes of uranium! Oh my God, that would cost hundreds of millions! And even more! Luo Yaoguo's brother-in-law Lu Ming seems to have drunk a little too much now, and as soon as he saw Luo Yaoguo, he immediately came up. He began to complain: "You put me in charge of these factories, but you won't tell me what they are used for? This is ridiculous! ”

"Be quiet, Ziyan." Luo Yaoguo frowned, and while turning the wine glass with his hand, he felt a little embarrassed: "Of course, these factories are used to make secret weapons, and the entire U project is to make secret weapons, and this secret weapon is very important to our country, okay, that's all I can tell you now!" ”

"That's all? With these words, Hu Hanmin is willing to allocate the money? It's incredible! Lu Ming complained. Cocking his neck, he poured another large cup. Obviously, he is not in a good mood now, but he was sent from the position of deputy minister of armaments to a remote place like Lanzhou to take charge of some inexplicable factories!

"It's not convenient to talk here, you come with me." Luo Yaoguo dragged him to the corner of the restaurant, and put Natalie in charge of stopping any idlers from approaching. Only then did he ask again: "How is the situation in Lanzhou?" ”

"What do you mean? If you refer to the progress of the construction of our factories, it is very good, and it is going according to the plan. But if you're asking about that place, it's terrible...... Land degradation, water conservancy is in disrepair, and drought has been going on for years. Local finances can only be described as collapsing. The six-year compulsory education that should be implemented on paper cannot even be implemented in all the provincial capitals! It's too poor and too stupid! I can't believe it's part of China...... And it is also the jurisdiction of the national government! Supplement, compared with your secret weapons, shouldn't we invest more money in supporting the development of the western provinces and regions? The country still has such poor provinces, but we are spending money indiscriminately! Make some secret weapons that I don't know if they are useful or not. Speaking of this, Lu Ming lowered his voice again: "I'm not the only one who has these thoughts. People in the Ministry of Armaments who know about these projects think so, and some people go to make a small report to Zhan Gong, saying that we are wasting public money! ”

"Is that just worrying about that? There is no problem, Zhan Gong will not ask about this matter. Luo Yaoguo said: "How much uranium do you have now?" How's the preservation? ”

Lu Ming sighed lightly and thought for a moment: "There are five hundred tons of uranium ore and about fifty tons of uranium oxide...... The ore was mined in the Kolyma Mountains, where the mine has now been built and large-scale mining is about to begin. Uranium oxide was bought from the Czech Republic, and that kind of thing has strong radiation, so there are special warehouses for collection, and there is a battalion of gendarmes guarding those things, there should be no problem. ”

"Well, uranium is radiant, and that kind of radiation is harmful to the human body, you have to be careful, by the way, do the workers who process uranium ore have the corresponding means of protection?"

"There are protective suits, which are provided by the Germans, but I wonder if it is useful? In addition, Wang Junhao provided some prisoners...... Although they are prisoners, they can't ...... It's going to die! ”

Luo Yaoguo waved his hand and stopped Lu Ming's words, he didn't want to listen to these words, because he would feel guilty if he heard too much. It was a sudden rain outside, the wind was howling, the thunder was rumbling, and a shower of rain poured in through the open doors and windows, dissipating the stuffiness of the house.

"Ziyan." Luo Yaoguo looked at the rolling dark clouds and the constantly falling lightning in the sky outside the window, and his voice was a little distant: "I know that there is a kind of bomb that uses uranium-235 with a purity of more than 90% as a charge, and one such bomb can sweep away the entire Wuhan!" So we have to have it! You may not understand why uranium-235 is so powerful, or even how it can explode...... But I can guarantee that in a few years, you'll find out. But then we won't be like this. Using the world's technology and ingenuity to separate uranium-235...... And we can't get this kind of bomb out in the first place on our own! ”

"Is there any other country working on this bomb you are talking about?" Lu Ming's drunkenness seemed to disappear all at once, and his voice trembled slightly. He naturally believed what his brother-in-law, who controlled the Military Intelligence Bureau and seemed to know everything, said.

Luo Yaoguo drank the champagne in the glass in one gulp, and lightly spit out two words: "Soviet Union!" ”

……

Comrade Stalin, of course, did not know that the USSR was "working" on the atomic bomb! All he was thinking about now was the war in the Far East, and in any case he must eliminate the Tsarist regime in Vladivostok before China, Germany, Poland and other imperialist countries could complete their preparations for war! And at all costs!

And the scientists in the Soviet Union don't have the heart to do any research at the moment, and their most important job now is to convince the housekeepers in blue hats that they are against Empress Anastasia! Thanks to Wang Zhongyi, a barbaric warlord. At present, the Soviet Union's suppression is no longer engaged...... Trotsky's father and son are dead, so what is there to keep in it? However, the enthusiasm of the internal affairs staff was very high, and they soon found a new focus - the White Guards! That is, the Russians who have a little to do with the aristocracy, the White Army, the capitalists, the Mensheviks, the Socialist-Revolutionaries, and the Russian scientific community and the universities are of course the hardest hit areas!

In a long, low-roofed, dimly lit room in the Kremlin, with a row of maps hanging on the wall, Stalin sat at one end of a painted conference table, a pile of papers on a green cloth in front of him. The tyrant's ashtray was full of ashes, indicating that the Soviet investor had been working here continuously for a long time. He was now wearing a rough uniform, which looked loose and wide, and he looked tired. His secretary Pavlov sat next to him. It was a thin, pale, dark-haired young man with a cautiously submissive expression. There was no one else in this big room. When the uniformed protocol officer invited a Japanese in a tuxedo in, Stalin stood up and shook hands with them. Silently, he made an elegant gesture and invited them to sit down in their chairs, and looked at Yosuke Matsuoka, the secret envoy of the Emperor of Japan, with inquiring eyes.

Matsuoka handed him a letter and a heavy lead box wrapped in flannel, and said in Russian: "Mr. President, this is a personal letter from His Majesty the Emperor of our country, and a very special 'gift' - a small piece of uranium dioxide, refined from uranium ore in the Kolyma Mountains of the Soviet Union. "Stalin was very careful to open the emperor's envelope with a paper cutter. He took out the pale golden letter paper and handed it to Pavlov. Pavlov looked at it and told Stalin in Russian the gist of the letter. Just ordinary greetings and nonsense about the desire to deepen friendship with the USSR, there is nothing to it.

Stalin was a little disappointed and had to open the lead box again. Matsuoka hurriedly said: "Slow, Mr. President, uranium is very radioactive. It's very harmful to the human body, so don't touch that thing and leave it to the Soviet scientists to study. ”

Stalin turned this heavy lead jar in his hand and said: "Mr. Matsuoka, you just said that the uranium in this place was mined from the territory of the Soviet Union?" What's the use of this thing for you? And what does it have to do with the secret negotiations between our two countries? Could it be that your country wants to continue to possess that...... Uranium ore? ”

Matsuoka Yosuke took out a list from his purse and handed it to Stalin along with a copy of the newly published Pravda, and said, "Mr. President, to be honest, we in Japan do not know what uranium is used for, but we know that the Chinese have been fascinated by this kind of research during this time, and have spent tens of millions of dollars in Germany and the United States to customize all kinds of machinery and equipment, and there seems to be a large secret factory related to it being built in western China." It is the Chinese side that is interested in this thing, and we are sure that they are working on some kind of secret weapon! And this newspaper I bought on my way here featured the Jewish female scientist Lise. A research institute led by Meitner discovered three isotopes of uranium! This Jewish female scientist and a few other Jewish scientists from Germany are now working for the Chinese! The project they are working on is likely to be related to uranium as well. We believe that this information must be taken seriously by both of us......"

Unexpectedly, before he could finish his sentence, Stalin let out a short, shrill laugh, and then spoke quickly in Russian to Yosuke Matsuoka: "What do you want to say?" Are the Chinese working on an unknown secret weapon? Just by them!? And even if so, what does it have to do with us? I don't understand what you came to Moscow for? Want to develop a secret weapon jointly with the Soviet Union? If you withdraw your troops from the territory of the USSR, then we will start joint research and development, even if the USSR pays for all the research funds! But now...... Our two countries are still at war, do you think it is appropriate to discuss such an issue? (To be continued)
