Premier Yuan's diplomatic campaign continued, and on November 5, after concluding his visit to Saudi Arabia, he arrived in Cairo, Egypt, by special plane for a visit.

Although I don't know much about history, Li Guang Middle School still remembers a little bit in the history class: In November of the fourth and third years, there was a major event in the history of World War II --- the Cairo Conference. This meeting was significant, as China entered the world's top four at this meeting, and it was a conference that determined the post-war landscape of Asia.

Li Guang knew about the meeting, and even knew some of the contents of the Cairo meeting. However, the human brain is not a computer, and Li Guang only knew that it was November of the fourth or third year, but he did not know the specific date of the meeting. Therefore, Premier Yuan and his entourage, who went to the "rubbing meeting", had to wait in Cairo early. However, people like Premier Yuan will not be idle, and they may be able to do something good from Egypt.

The reason why Su Qing and Xu Zhan hurried back to Myitkyina, Myanmar, was that the war was still going on, and it was definitely not normal for the troops to have no military commander. Second, Su Qing wanted to find his "uncle" Chairman Jiang to do some private exchanges.

Wang Shi, who served as minister of the Haitang Kingdom in the United States, is now also busy lobbying Truman. In the U.S. election of '44, Truman was nominated by Roosevelt as his running mate, that is, the vice presidential candidate. Truman's voice is now rising rapidly and his influence is expanding day by day. Li Guang has invested in Truman for many years, and it is almost time for the return period.

The people who travel are so good, and the power of the golden finger is revealed. However, the specific step that can be achieved still requires the efforts of Premier Yuan, Foreign Minister Yan and other diplomats.

Li Guang admits that in this regard, he is seriously incapable of crossing people. has been thinking as a soldier all year round, and now Li Guang has also found that his style of doing things is becoming more and more direct, which is really not suitable for diplomacy. A mind game to play Rippy.

So while paying attention to the information in Cairo, Li Guang once again turned his attention to several important projects he led.

Although the world is big, it is interlocking, and a spider silk sticking out of an inadvertent corner can connect the two countries, Haitang and the United States, and two secret projects.

In Haitang, the most classified plan A, that is, the nuclear bomb program, has recently had a little bit to do with the Manhattan project of the United States.

After several years of hard work, Haitang Guo's Plan A. Great progress has been made. Not only is there enough uranium ore now, but now Bohr and his sons, together with a group of scientists from the Tang Kingdom, have solved the process of enriching uranium. Li Guang thought that he had pointed out the right way to Bohr and his sons, and the progress should be very fast. But in fact, the progress is really not fast.

The development of nuclear bombs in the Haitang Kingdom now has three obstacles.

First, the high-speed centrifuge required for enriching uranium and the electricity required to run a nuclear enrichment plant. In this regard. For Haitang Kingdom. The main thing is money - invest in a hydroelectric power station, buy materials to start manufacturing machines, invest in factories. It doesn't cost much on this link. However, after calculating the calculations, it was learned that without the investment of 2 billion Tang Yuan (50 million US dollars), it was impossible to imagine the enriched uranium needed for two or three nuclear bombs.

Second, the radioactive element required for the ignition device of the atomic bomb - plutonium. This. For the Bohrs and sons, it was the biggest problem, because in order to get plutonium, it was necessary to build a nuclear reactor. It's no longer a question of investment, as is the case with many research projects. Investing doesn't always pay off. Although Bohr and his sons have now turned their energies to the study of nuclear reactors, no one dares to guarantee whether they will produce results. Li Guang, on the other hand, also provided a rough plan with his limited knowledge of nuclear physics. However, how did Li Guang know that the two substances necessary for the production of reactors, heavy water and high-purity graphite, are not so simple things.

High-purity graphite, Haitang has the best graphite mine in Africa and even the world, although it is difficult, but it seems to be picking cabbage core, and it takes huge material and financial resources to get a lot of high-quality graphite, even so, it also needs to be processed, which can get the right high-purity graphite. Either way, the engineers believe that the problem can be solved in the end, and the cost will not be terrible.

However, the heavy water thing really surprised Li Guang again. This thing is not difficult to say, ordinary water contains heavy water, and the production process is just the electrolysis of ordinary water, and heavy water will not be electrolyzed. Ordinary water is turned into oxygen and hydrogen, and heavy water is left.

Speaking of simplicity, the equipment is more complicated, and the more difficult is the supply of electricity, in short, it is extremely power-consuming. In fact, if you know a little bit about the history of World War II, you will know that the Germans built a heavy water plant in Norway, and such an important thing is not in the country, and you will know the reason - electricity. Norway has an abundance of hydroelectric power, and the Germans use electricity there.

In short, there are countless unknown difficulties on the road ahead, and it is not just a matter of spending money. Li Guang has a headache, but in any case, it is necessary to allocate research funds first. As for the construction of nuclear reactors, it is not yet time for a while and a half.

Thirdly, the manufacture of atomic bomb bodies. Note that this is not a design. You must know that the schematic diagram of the principle given by Li Guang at the beginning has been designed long ago with the efforts of a leading engineer.

And the difficulty is actually mainly in the manufacturing aspect. Of the three roadblocks, this can only be regarded as a small tiger. But science is a hard commodity, and it can't be faked in the slightest. You know, a nuclear bomb is dropped from a high altitude and then explodes. It is not easy to fall from a high altitude and not damage the structure of the nuclear bomb with a huge impact. Otherwise, why did New China's first nuclear bomb simply be put on an iron frame and detonated? Without him, the difficulty of manufacturing is low.

A nuclear bomb is not a grenade, and there is absolutely no room for error. Throw it down and don't explode, but it's not just a laughing and generous, it's a laughing stock for eternity. Li Guang can't afford to lose such a person, and Haitang Kingdom can't afford to lose it.

So far, the Haitang Kingdom has not been able to build even an airborne aviation-to-ship armor-piercing bomb. To create an absolutely reliable nuclear bomb body, it takes time, money, equipment, and technology.

Originally, a nuclear bomb was an extremely difficult thing, but why was Li Guang in a hurry recently?

Because, on the road to nuclear bombs, the Americans are likely to have gone ahead of the Haitang Kingdom.

A leaf knows autumn, a glimpse of the whole leopard. Recently, the U.S. government came forward and asked to order high-purity graphite from Haitang. The United States is rich in uranium ore, and just by looking at the technical indicators, Li Guang knows that the Americans are definitely using them to build atomic bombs.

In Germany, there is actually a graphite-related thing. Historically, Germany bought high-purity graphite from French businessmen, also to build nuclear bombs. However, the French businessman took a big step and deliberately sold the bad varieties of graphite to Germany, which seriously delayed the development of the German nuclear bomb. And the source of those graphites is actually Datang Island.

In this regard, Li Guang was not polite, and directly asked for 10,000 US dollars a ton, and it was not discounted, anyway, the Americans have money, and the uranium ore they buy is not tens of thousands of US dollars?

The benefits of having a site are obvious, and you can easily get it for millions of dollars. However, Li Guang's vision is also higher now, and he was only happy about the receipt of millions of dollars for less than a minute, and then fell into contemplation again.

The United States is powerful. The progress of less than two years exceeds the progress of the four-year plan of Haitang Guo A. Li Guang is already admiring the speed of the United States, but if we compare it with history, the progress of the Americans is actually much slower. Li Guang is not clear about the historical position of Bohr and his sons in the US nuclear bomb project. These two were the No. 3 people in the nuclear bomb project, that is, the Manhattan Project, and they were the No. 1 people on the front line of real scientific research. The other two Oppenheimer, Einstein has a high status, but it is indeed similar to a mentor such as direction guidance, especially Oppenheimer should actually be regarded as a scientific research management talent.

Although it is said that a large-scale scientific research project like this cannot be won by one or two people, it is natural that the progress will be delayed without a genius like Bohr and his son, who have both won the Nobel Prize.

Li Guang didn't know, he was just inferring according to his thoughts: In this way, the Americans' nuclear bombs are probably ahead of Haitang. Li Guang built a nuclear bomb, one to throw it to the little devils for fun, and the other to consider the future development of the Haitang Kingdom.

If, according to history, the United States dropped the atomic bomb and the little devils surrendered, it would not be the turn of the Haitang Kingdom to grow mushrooms in Japan.

In this regard, Li Guang needs to use his brains. (To be continued......)
