Zhang Xuewu equipped the folding three-edged bayonet with the Zhonghua Type 1 semi-automatic rifle with a phosphating process to treat the surface, and replaced the common baked blue with matte, because when the bayonet was smelted with steel, a certain amount of arsenic was added for the needs of the metal alloy composition, and the steel body containing arsenic was exposed after the phosphorus coating on the surface of the battlefield was worn out, and it was difficult to heal even if it only scratched the enemy's skin.

The three-edged bayonet is not absolutely perfect, it is easy to break and crack when it is hit and twisted by huge resistance, the three-edged bayonet is heat-treated, the hardness is extremely high, and there is a certain tenacity, as a perfect combination of bayonet and rifle, although the length is a little shorter than the 38-type bayonet of the army, but after all, the Chinese semi-automatic rifle does not completely rely on the bayonet as the main combat power of the weapon, and its accuracy and rate of fire suppression as the embodiment of its main surname.

Therefore, there is no need for the three-edged bayonet to compete with the 38-type bayonet in terms of length, and when fighting at close range, the single-shot supinator single-shot rifle is definitely not the opponent of the semi-automatic rifle, and in theory, a 16-man reinforced combat squad equipped with 10 Zhonghua Type 1 semi-automatic rifles and two ZB-26 7.62 mm caliber light machine guns and Mauser sniper rifles can effectively suppress a squad of the Yue Army in terms of firepower.

Although Zhang Xuewu is not a supporter of the theory of winning by firepower, Zhang Xuewu believes very much that firepower superiority can be extremely effective in reducing the casualties of his own officers and soldiers.

Although no money is absolutely impossible, money can't buy life and health, you can't buy a smile but you can't buy sincerity, let alone time! Therefore, Zhang Wu is very willing to invest in the upgrading of weapons, because the troops and resources of the 10th Theater are limited, and there is no comparison with the Nanjing control area, the Yueben side, and even the Soviet side, so Zhang Xuewu can only take the high-precision route.

Because of the anti-Jewish movement in Germany that began in 1933, Zhang Xuewu chose a very big bargain, and Zhou Ying recruited outstanding scientific researchers for him in the United States and Europe, and a large number of foreign students and elites who served the country invariably chose to go to Rehe after returning home, although Rehe is a remote place in China, but it has already become history, and now China's most advanced laboratory is in Rehe, and the largest wind tunnel system in Asia is in Rehe, Rehe, Chahar, The capacity of generator assembly machines in the three provinces of Suiyuan accounts for as much as 52% of the country's total, and the most important thing is that the Baotou industrial base has gathered a large number of world-class top experts and scientists.

For example, Shen Hanze personally came forward to use a lot of money and the world's first-class laboratories and equipment to transfer Enrique, who has not yet won the Nobel Prize, from Italy. Fermi deceived Enrique to Baotou and actually had unlimited style. Fermi was in great trouble in Italy at the time, mainly because his wife was Jewish, and the Italian fascist government enacted a set of laws that imitated the Jews in Germany, because the anti-Jewish movement was going on all over Europe, not only in Germany and Italy, but also in France and England, and many of these decrees were still in force until the end of World War II.

It's just that Britain and France are the victorious countries of World War II, so all the black pots can only be suffered by the Germans, if there is no concentration camp massacre, the Germans do basically the same as Britain and France, under the pretext of war to control the economy, annex Jewish enterprises, confiscate their gold, jewelry and property.

And Fermi is a scholar who is strongly opposed to fascism, and always says something inappropriate when something is inappropriate, so Enrique. Fermi's presence in Italy under Mussolini's rule was an extremely dangerous affair.

So, Enrique. Fermi and his entire research group on quantum physics were all forced by Shen Hanze to Rehe in China through his relationship with the United States. Fermi's way to the United States was blocked, because now all countries in the world, including the United States, do not have a good impression of these madmen who spend a lot of money all day studying the so-called ethereal theories and proving that physics is the creator god, and these guys may study things for a hundred years? Two hundred years are still standing still, but the cost of them is staggering, and under the premise of pragmatism, no one wants to invest their limited military spending on research without any hope.

And in fact, Enrique. Fermi had realized that a fissioned uranium atom could release enough neutrons to cause a chain reaction. Fermi, like several of the world's leading quantum physicists, immediately foresaw the potential for such a chain reaction for military purposes, but no one in Germany, Italy, or the United States wanted to pay for this extremely expensive experiment.

That is to say, Enrique. Fermi can only stay in the theoretical stage, after all, Enrique at the moment. Fermi had not yet won the Nobel Prize, and the world's understanding of the so-called atomic theory was far from as urgent as it was in 1939 and 1940.

Enrik. The Baotou Underground Research Institute where Fermi is located is a huge underground seven-storey living bunker, the entire bunker is embedded in the mountain, and the area is a first-class military restricted area, Zhang Xuewu does not directly participate in the so-called research, but Zhang Xuewu understands some of the so-called "secrets" of the atomic bomb through the network of later generations?

The theories and methods mastered by Zhang Xuewu can be said to be summed up by the world's top physicists after hundreds of thousands of repeated calculations and demonstrations, and countless detours and wrong paths, but for Zhang Xuewu, those are just formulas and processes that can be seen everywhere on the Internet in later generations.

Therefore, Zhang Xuewu believes that as long as he gives enough hints to the research team codenamed "Flame", Enrique. It is also extremely possible for the research team led by Fermi to conquer the nuclear fission control technology, but Zhang Xuewu realized the importance and absolute secrecy of this matter.

Enrik. Fermi always ignored Zhang Xuewu, the "gold master" who provided top-notch equipment and met all his requirements, and Zhang Xuewu naturally didn't dare to directly show what theories, methods, and formulas he proposed, because that was too shocking.

For this reason, Zhang Xuewu can only use his own people in the experimental group to constantly introduce the so-called inspiration, and everything is done as if it is accidental, but it is difficult for a clever woman to cook without rice, there is no theory and no uranium ore, everything is in vain.

There are more than 170 kinds of uranium minerals known in the world, but there are only 20 or 30 kinds of uranium ores with industrial mining value, and nuclear weapons refer to the use of energy released by nuclear fission or fusion reactions that can be self-sustaining, resulting in explosive effects, and the explosion of nuclear weapons not only releases huge energy, but also the nuclear reaction process is very rapid, and can be completed in a microsecond time. As a result, extremely high temperatures are formed in a small area around the explosion of a nuclear weapon, and the surrounding air is heated and compressed to rapidly expand, generating a high-pressure shock wave.

Nuclear weapons detonate on the ground and in the air, and can also form fireballs in the surrounding air, emitting strong light radiation. Nuclear reactions also produce various rays and fragments of radioactive matter, and the strong pulse rays radiated outward interact with the surrounding matter, causing the process of growth and disappearance of electric current, and as a result, electromagnetic pulses are generated, and it can be said that the emergence of nuclear weapons has had a major impact on the strategy and tactics of modern warfare, and even subverted the way warfare is conducted.

Zhang Xuewu is very aware that nuclear weapons are mainly fission weapons made by using the fission chain reaction principle of heavy atomic nuclei such as uranium-235 or plutonium-239, and uranium-235 is the main charge of the atomic bomb, and it is not easy to obtain a high concentration of uranium-235, because the content of natural uranium-235 is very small, about one hundred and forty uranium atoms contain only one uranium-235 atom, and the remaining one hundred and thirty-nine are uranium-238 atoms; In particular, the two are isotopes of the same element, and there is almost no difference in their chemical properties, and the relative mass difference between them is very small.

Therefore, it is not possible to separate them by ordinary chemical methods, and the method of separating light element isotopes is useless, so in order to obtain high concentrations of uranium-235 elements, the most effective method in the early days was the "gas diffusion method".

What makes Zhang Xuewu very helpless is that China's uranium ore reserves are however, the largest uranium mine is located in the Xiangshan area of Le'an, Jiangxi, and is dominated by hydrothermal vein and sandstone deposits, the deposits are mostly medium and small scales, uranium grades are mostly medium and low grades, and the ore body is buried deeply, mostly deep underground mining, the main miners are distributed in Guangdong, Jiangxi, Hunan, Guangxi, Liaoning, and only Zhongshan County in Guangxi can be mined with today's technology, which is also the birthplace of China's first uranium ore in later generations.

For this reason, Zhang Xuewu can only think of a way, the scientific research group over there Enrik. Fermi is urging almost every day, and the clouds of the war are imminent, Zhang Xuewu can only secretly send people to Shanmu Village, Honghua Town, Zhongshan County, Guangxi Province to investigate and related mining, and the transportation of ore is another thorny problem.

In fact, Zhang Xuewu also knows that he still has a good and easier way to obtain uranium ore, whether it is the German side or the Soviet side at the moment, they will sell some of it to Rehe, but in order to strengthen the secrecy of the "Flame" project, Zhang Xuewu can only rely on himself!

From a rifle to an atomic bomb, Zhang Xuewu is researching, but Zhang Xuewu has always liked to prepare with both hands, because there are two kinds of nuclear bombs in different senses, one is still far away, and the other is a financial nuclear bomb!
