In addition, the forced implementation of curfews in many places in the United States, coupled with the fear of people affecting work, the economy and industrial production of the United States have also been greatly affected, but it is quite accidental that Roosevelt can be gaffed and cry for a while

Although it is very likely that he will be protected by the embassy or consulate of his motherland after revealing his identity, the prince knows that what he has done this time is too much, so he would rather die in the United States as a Japanese than risk bringing great disaster to his motherland. Despite this, out of the instinct of survival, the prince still relied on his cunning and ferocity to successfully escape again and again under the siege of the American military police, during which he killed and wounded no less than 100 American military and police

Unconsciously, the prince has come to New Mexico in the middle of the United States from the western part of the United States, the reason why he came here is because he once saw Hu Weidong mark two red dots on a map of the United States, one of which is in the mountains of New Mexico, he was very curious at the time, and now that his life is short, he simply came over to solve the mystery in his heart, and compared to the red dot marked as "Oak Ridge" in Tennessee, this place marked by Hu Weidong as Los Alamos is undoubtedly much closer.

Before he could get close to the town, which was not marked on the map of the United States, the prince found that it was heavily guarded, but it was not difficult for him, and long before he separated from his subordinates, he used wigs and other props to disguise himself as a Caucasian, as long as others did not get too close. It was difficult to find the problem, and the conspicuous rifle had been discarded by him, leaving only two pistols and four grenades to defend himself, which greatly facilitated Wang Zicai's infiltration. What's more, perhaps for the sake of secrecy, or perhaps to prevent the psychological pressure of the "residents" of the town from affecting their work, the Americans, although they were on strict guard, adopted a "loose on the outside and tight on the inside" approach, which was okay against ordinary enemies, but it was impossible to prevent a super-first-class agent like Wang Zicai from infiltrating it

Because he was familiar with this temperament and style when he was by Hu Weidong's side. The prince just briefly observed it after sneaking in. I found that a good percentage of the city's residents were scientists, and I couldn't help but wonder, "What kind of major topic is the U.S. government studying with so many scientists?" ”

In order to accumulate data for the calculation of critical mass. At this time, a very dangerous experiment was being carried out in a building in the small town of Los Alamos, the plutonium-239 (Note 1) alignment experiment conducted by Canadian nuclear scientist Dr. Sroda. To put it bluntly, this experiment is very simple. It is to combine two pieces of high-purity (above the weapon level) plutonium-239 on the slide of the test bench. See if there is a nuclear reaction (the surface is coated with a thin layer of phosphor, and the radiation is enhanced to a certain extent to excite blue light. ）。 If no nuclear reaction occurs, the critical mass is greater than the sum of the masses of the two pieces of plutonium-239. The next experiment will be larger than this one, with two pieces of plutonium-239; If it happens, it means that the critical mass is less than the sum of the masses of the two pieces of plutonium-239, and the comparison with the previous reaction can gradually narrow the error between the estimated value and the accurate critical mass, providing guidance for the United States to build an atomic bomb.

Of course, for the safety of himself and the whole city, once the nuclear reaction occurs, Dr. Sroda must use a screwdriver to separate the two pieces of plutonium-239 together, because the experiment is carried out gradually, even if the combined plutonium-239 can reach a critical mass, it will not exceed too much, and the fit is not as tight as when the real atomic bomb is detonated, so the speed of the nuclear reaction will not be too fast, at least a few seconds before it will enter the uncontrollable stage, as long as it is focused enough, It is completely possible to separate the two pieces of plutonium-239 in time and abort the nuclear reaction, not to mention that there are several of his assistants next to him, even if Dr. Sroda reacts half a beat slower, several of his assistants should be able to react in time.

The reason why the U.S. government agreed to carry out this seemingly extremely dangerous experiment was partly because it was in a hurry and hoped to build an atomic bomb as soon as possible, and on the other hand, it was confident in the mechanism of "multiple insurances". But what the Americans never expected was that an enemy would come to this "Los Alamos National Laboratory", which even the vast majority of Americans did not know

It must be admitted that the Americans did a pretty good job of security, and even Wang Zicai, who managed to infiltrate the city, was quickly exposed, and was chased everywhere by the swarming American military police. However, the Americans, who were afraid to use automatic weapons and heavy weapons, failed to kill the prince on the spot, and instead fled into Dr. Sroda's laboratory. Since this is one of the most classified laboratories, the pursuing American military police did not know what it was up to, so they made a wrong decision, because they were afraid of accidentally injuring the scientists in the laboratory, and even more afraid of being escaped by the damn "rat", they did not immediately rush in, but chose to surround the laboratory, and at the same time kept shouting for the prince to come out and surrender

Note 1: According to the story that he tested uranium-235, the critical mass of uranium-235 is very large (more than three times that of plutonium-239), and it is difficult to use a screwdriver to move it flexibly even on the slide. Although the relevant tests of uranium-235 were also conducted by Dr. Sroda, the experimental method was different.

In addition, the accident in history actually happened after World War II, not before World War II, and Dr. Sroda, who thought that after the end of World War II, there was no need to continue to research this terrorist weapon, repeatedly offered to return to Canada to become his university teacher, but it was not easy to find another scientist who was willing to do this dangerous work, so the U.S. government resolutely refused to allow or even restrict his personal freedom, Dr. Sroda was very emotional, and it was precisely because of his absent-mindedness that the accident happened

PS: There is another reason why plutonium-239 is written here, that is, no matter how strong the United States is, it is impossible to produce enough uranium-235 to make an atomic bomb in 1943, but with plutonium-239, as long as there are enough reactors, it is possible, and in the second half of 1943, when this incident occurred, the United States could have invested more in "Manhattan" than in history (to be continued......
