In Uruguay, Li Guang carried out the most secret and important thing, and very few people knew about it.

In the Tangcheng Development Zone, there is a brand-new villa that is extremely quiet and luxurious. This is one of the best villas in Premier Yuan's real estate industry. This villa was originally intended by Li Guang to be given to his father-in-law Yuan Ye. But now, in order to show the importance of talent, he gave it to the family he hijacked from Denmark - Professor Bohr's family.

Professor Bohr is the leader of the famous Copenhagen School of quantum mechanics, and if the greatest achievement of the Naval Resistance Army's trip to Europe is not the arms, but Bohr and his son Bohr Jr.

Li Guang only knew such a figure when he was in physics class, and Bohr was not only a leading figure in nuclear physics, but also occupied an extremely important position in the Manhattan Project in the United States. But the reason why Li Guang can remember this famous figure is not these two factors, but that this father and son are in Tainiu, and the cow is a mess, and both father and son have won the Nobel Prize.

When the PC number passed through Denmark, Li Guang thought that his deal with the Germans was not in place, and he wanted to recover his losses from somewhere else, so he remembered such a person, so he was not very civilized and "invited" back.

The process of "please" was quite uncivilized, but the subsequent treatment was the best among the naval resistance forces, and Li Guang even gave up the cabin where he lived.

In addition to these, Li Guang also gave the villa he was going to contribute to his father-in-law to the Bohr family, which was very thoughtful to the family in terms of material and politeness.

Li Guang is not a very persuasive person, but the conditions offered make it impossible for the father and son to refuse. Bohr's family is of Jewish descent, and in history in four or three years, Bohr was hunted down by Nazi Germany because of his Nazi ancestry, and fled to Sweden, England, and later to the United States.

One of the biggest reasons why Bohr and his son agreed to work for Li Guang was not the conditions offered by Li Guang, but when they saw that Li Guang had rescued thousands of Polish Jewish women, and the personnel recruited in Denmark had also been arranged to work, their inner sense of identity was strengthened.

Li Guang hired the father and son as professors on the grounds of cooperation in scientific research projects. The father and son were responsible for theoretical preparation and some basic research for Project A, as well as taking several students and acting as their mentors.

What's more, Li Guang promised to build a nuclear physics laboratory for them, with Mr. Bohr in charge of the work, and he could recruit personnel from all over the world.

This kind of condition is not so easy to obtain even for a great scientist like Bohr, so the two sides reached an agreement very happily.

After the two sides signed a confidentiality agreement, Li Guang took out a schematic diagram of the atomic bomb. This diagram is just a sketch, only the principle, not the data. And Li Guang didn't dare to guarantee that it was correct.

As a science and engineering student, Li Guang did not have much interest in the nuclear bomb, a weapon of mass destruction, but occasionally searched the Internet for the structure of the atomic bomb, and in his spare time during the voyage, Li Guang drew this drawing.

At the beginning of 1939, the German chemist O. Hahn and the physical chemist F. Strassmann published a paper on the fission phenomenon of uranium nuclei. In early September of the same year, the Danish physicist Bohr and his collaborator J.A. Wheeler theoretically described the process of nuclear fission reaction and pointed out that the best element that can cause this reaction is the isotope uranium-235.

It has only been 40 years now, and except for the United States, which has paid attention to this, other countries have not mentioned this research at all, and most of them are still scientists conducting theoretical research.

Bohr is also very interested in Li Guang, although Li Guang is not a scientific and technological talent, but he has listened to a lot, and he still has a lot of common language with Professor Bohr. In particular, he was a supporter of Bohr's theory that the isotope uranium-235 was the best fission material.

It's not that Li Guang has such a theoretical level, but he just knows it.

For example, the sketch given by Li Guang is also a priceless treasure for Bohr. These scientists can study the mechanism of the explosion, but the progress of research is far from completing the structure of the atomic bomb. Don't look at such a schematic diagram of the structure, it can save people countless detours. The two great scientists were so precious about this picture that they didn't even notice Li Guang's departure.

Scientists did not know that they had opened Pandora's box until the atomic bomb exploded, but scientists in the past 40 years have not really realized the horror of the atomic bomb, and their attitude towards such technology is the spirit of diligent research.

Li Guang didn't know much about the atomic bomb, but compared to the scientists of this era, it was actually not too little. Of course, he knew it, but he didn't know why.

At the beginning, Li Guang sorted out his plan A, and he found that he was missing too many links. First of all, he didn't understand the critical yield of a nuclear explosion.

To put it simply, the principle of a nuclear bomb is that two or more pieces of uranium-235 below the critical yield are close together at an ultra-high speed of explosion to reach more than the critical yield, and then detonated with a neutron source.

So the equivalent thing is so critical that you have to find a scientist to calculate it. Fooling around and not saying whether you can do it or not, just don't blow yourself up if you do it, that's a joke.

Another difficulty is that he knows a lot of things, but he still really can't figure out what is the most suitable for the neutron source and how to prepare it.

This also needs to be done by scientists.

The final difficulty is mining, beneficiation and specific manufacturing. And Li Guang has solved one of them, mining.

As a later man, the gold finger function was not completely scrapped, and he still remembered a very important link in his mind, the separation of uranium-235 by gasification.

Don't look at the key links in all the links, and there will definitely be fewer detours, but how big the gap is, Li Guang really has no spectrum.

Yuan Chou's work in Tonga and Australia was silent, and few people in the Maritime Resistance Army knew that Tonga's No. 3 Island was the territory of the Haitang Kingdom. But Yuan's work was fruitful, and thanks to Li Guangzhi's knowledge of the uranium mines in Australia, Yuan Chou was quick to find the ore. Now Yuan Chou has been quietly mining this ore in the name of iron ore mining. In fact, Australia does not pay attention to this ore at all, and there is not even a single person in the political axe who knows about this terrible thing. Historically, Australian political axes only began exploring for this mineral in 1944. So now Yuan Chou's activities have not attracted the attention of the Australian political axe.

At the beginning of July, the first batch of more than 300 tons of ore mined by Yuan Chou was delivered to Tonga Island 3. For Li Guang, only 300 tons of ore is only the smallest step. If you know the amount of uranium ore, you know what a lot of work it is. The grade of uranium ore is generally below 0.3 percent. Most of the refined uranium is uranium-238, not uranium-235, of which uranium-235 is only one hundred-and-forty.

A little calculation shows that if you want to get ten kilograms of uranium, I am afraid that you will have to toss tens of thousands or even hundreds of thousands of tons of ore, which is definitely not easy.

At the beginning of the year, Professor Yuan recruited dozens of real top talents for Li Guang, among which there were many celebrities and stars. Li Guang was afraid of delaying these hopes of China, so he sent them back to the United States to continue their studies. When those Chinese elites arrived in Uruguay, the research institute would be officially established.

Bohr and his sons are actually quite interested in getting uranium ore for experiments, and are already working on experimental equipment. Their first task is to find the right beneficiation process.

After being busy with many chores in Uruguay, Li Guang could have taken a plane back to Shixiang Island, but he couldn't leave the fleet, a group of rookies could have problems piloting this kind of giant at any time, and after sailing on the sea for so many days, Li Guang, as a "talent" specializing in mechatronics, personally repaired the battleship a lot of times.

During the three days of docking in Uruguay, the liberty ship finally unloaded some of its loads and put some supplies on the guano boat.

In this way, after some supply and personnel adjustments, Li Guang rushed to Shixiang Island with a mighty fleet.

Compared to the previous days, the speed of the fleet with the load adjusted immediately increased, and the fleet reached Stone Statue Island at the end of July.

Li Guang's voyage lasted four months, and the whole process can be described as thrilling, but the benefits are so huge that almost everyone rejoices.
