The United States' participation in the war has boosted the people of the European occupied areas and also given strong help from the Soviet Union.

Germany and Italy were very annoyed. The Tang Empire secretly signed a peace treaty with the United States, the Soviet Union, and other governments in exile in Europe. It was obvious that they did not want to sit and see Germany and Italy become stronger. Especially Germany controlled Britain and was building a strong naval force. The Tang Empire believed that Germany was more terrifying than the Soviet Union, so it made the choice to curb Germany's development and growth.

Fortunately, the Tang Empire remained neutral. Although it was just an excuse, Germany and Italy still dared not publicly offend the Tang Empire, for fear that the Tang and the United States would be even more difficult to deal with.

Although the United States declared war on Germany and Italy, its huge war machines were running and it took time to complete the recruitment of troops, raising materials, and assemble various war machines.

Especially the European continent, the British Isles and the fallen, the US military has no strategic support points in Europe, so it takes at least half a year or even longer to prepare for the attack on Europe.

The US military hopes to land with the Tang Empire on the Ireland Island, first recover Britain, and then use Britain as a springboard to attack Europe.

However, the Tang Empire did not want to turn against Germany and Italy at this time. After all, in order to export steel and other strategic materials to various belligerent countries, the Tang Empire built a large number of relevant factories on the ground. Workers worked overtime to increase production capacity and produced millions of tons of materials every day. Once the German and Italian market was closed, these materials would be accumulated because they could not be sold, which would have a huge impact on the economy and early capital investment of the Tang Empire.

Therefore, the Tang Empire was unwilling to lend Ireland to the US military for use. However, it did not want to offend the United States, so Zhang Meng came up with a solution that was the best of both worlds. He sent people to negotiate with the US representatives and bargained, and continued to delay based on the principle of delaying as much as possible.

On the other hand, the Tang Empire also took measures to speed up the cleaning of inventory, reduce hard currency such as gold and silver from Germany and Italy, and prepare to withdraw from fascist countries such as Germany and Italy.

The US military was preparing to attack Europe. This took a lot of time. Hitler was also preparing to accelerate the expansion of its naval, army and air force forces, especially the naval power. The German army controlled Britain and did not want Britain to counterattack the European continent as a stronghold of the US military. Therefore, it hoarded heavy troops in Britain and built huge fortifications to prevent the US military from landing.

In the Eastern European direction, the Soviet and German armies fought fiercely. Since the end of the Battle of Moscow in December last year, the German army suffered its first defeat and lost more than 500,000 troops. The morale of the Soviet army was high, and Stalin ordered a counterattack. However, he underestimated the combat effectiveness of the German army. As a result, three months after the counterattack, he was suddenly attacked by the German army. The Soviet army was defeated again and retreated to the vicinity of Moscow.

This time the German commander remembered and did not rush to attack Moscow, but waited for the cold winter to pass. When the weather was warm, he then fought a decisive battle with the Soviet army.

From March to June 1941, the Soviet and German armies had almost no major military operations. Both sides had small-scale infiltration operations and were saving their power to prepare for a major decisive battle.

In the Far East, the Kuomintang and the Communist Party had completed the agreement on the basic agreement of the coalition government. Although the Kuomintang and the generals within the Communist Army caused more than ten years of fighting and hatred, and occasionally made small moves, in the general direction, the Tang Empire strongly suppressed and restricted the two camps to accept the principle of democracy and adapted the national army. Chiang Kai-shek was about to fight a civil war, but unfortunately his arm could not twist the thigh of the Tang Empire, and he could only compromise in the end.

In the end, the Kuomintang and the Communist Party formed a democratic joint-offensive government. In the first twenty years, the Kuomintang and the Communist Party took turns to rule. Each term was five years, and 20 years later, the ruling party and opposition party were elected according to the principle of democracy. Because the mixed ownership economy proposed by Zhang Meng successfully tolerate the bourgeois interests represented by the Kuomintang and also represent the proletariat interests of the Communist Party, so that the core interests of both sides are not threatened, so that both sides can put down their weapons and end the civil war.

China has achieved stability, and Zhang Meng is the happiest. He successfully stopped the outbreak of the civil war, stopped the bloody tragedy, and saved hundreds of millions of people. This is a great good deed. Although many people within the Kuomintang and the Communist factions hated Zhang Meng to death and meddled with other people, the strength of the Tang Empire was there, so they could only curse behind their backs, but there was no way to deal with Zhang Meng.

Everything is under Zhang Meng's control. This feeling is very strange, like walking a tightrope on a cliff, dangerous and exciting.

Zhang Meng likes this dangerous game, just as he decided at the beginning that the Tang Empire was like Germany and Italy, which was a dangerous action, but Zhang Meng stopped just now and stopped when he was better. Now he broke out of Germany and Italy's burden and handled his relationship with the United States well, making the Tang Empire the biggest beneficiary of war.

However, Zhang Meng was very cautious. Although the exiled governments such as the United States and Britain and France were tolerant of the Tang Empire in all respects, the powerful military power of the Tang Empire would inevitably be feared by the United States. However, the current policy of the United States was to divide the Tang, Germany and Italy alliance and defeat them one by one. When the United States resolved Germany and Italy, it might not be a good face to the Tang Empire. At least Britain would hate the Tang Empire to the core.

Zhang Meng was not afraid, everything was in his plan, and he had a strategy to deal with it. If the Tang Empire had not been able to compete with the United States in terms of population war potential and there was still a big gap in industrial manufacturing capabilities, Zhang Meng might have followed Germany and Italy to the north to see what the outcome was.

But Zhang Meng is not a reckless man at the moment. After he tried hard, he found that the Tang Empire could not compete with the United States in terms of comprehensive war potential for a short period of time, he decisively stopped.

However, this does not mean that Zhang Meng gave up global hegemony. On the contrary, the Tang Empire acquired the global maritime strategic strongholds of the entire UK. Zhang Meng wanted to defend these strongholds. This is the basis for the Tang Empire to overthrow the United States and dominate the world in the future.

For this goal, under Zhang Meng's urging, the Tang Empire launched a nuclear engineering project with all its might, accelerating the development of nuclear weapons.

In the past, Zhang Meng felt that he had plenty of time, which was based on the original historical trend of World War II, but now history has changed. Intelligence shows that the United States and Germany are secretly developing atomic bombs, so time is no longer available. Zhang Meng ordered the acceleration of the development of nuclear weapons and strive not to be blackmailed by the United States, which has always been in a strategic initiative.

This is a guarantee that the United States will not settle accounts with the Tang Empire after the end of World War II.

Although the Tang Empire was founded only eleven years ago, it has always been at the forefront of the world in scientific and technological research, and has even been in the world's leading position in many fields. This is thanks to the global talent plunder and introduction plan of the Tang Empire. In addition, it has also been combined with sufficient R&D funds to burst out the huge energy of the Third Industrial Revolution with science and technology as its productivity, promoting the rapid development of the Tang Empire.

In the field of nuclear nuclei, the Tang Empire gathered more than 30,000 scientists, engineers and technical auxiliary personnel, with an investment of up to 1 billion Tang Yuan.

As the main person in charge, Tesla applied for a related patent for logic gate circuit forty years ago and replaced the relay with a vacuum tube. Under Zhang Meng's prompt and guidance, it had implemented an electronic calculator with electron tube as the main body five years ago, using binary values, reusable memory, programmable management, and replaced mechanical calculator.

This is a big breakthrough because the research of atomic bombs requires a large amount of computational data. The efficiency of mechanical calculators is not high and bulky. The implementation of electronic calculators allows scientists in the Tang Dynasty to calculate various data more quickly and accurately, and improve the R&D speed.

With the outbreak of World War II, in order to train strategic bomber pilots, the Tang Empire Navy asked the National Academy of Sciences whether it could develop a computer that could control flight simulators. The military's original idea was to use the computer to reflect the data generated by the pilot simulation operations on the dashboard in real time. Unlike previous training systems, the military planning system could simulate as realistically as possible based on aerodynamic models to make it suitable for various types of aircraft. Therefore, the National Academy of Sciences created the cyclone project, which created the world's first cyclone computer that can process data in real time and invented a magnetic core memory.

Subsequently, Tesla's computer R&D team further improved the design based on its defects and finally presented a program storage architecture. This system is the basis of all computers in the future and has also become an important helper of Datang Nuclear Engineering. A supercomputer with a computing speed of 20,000 times per second was developed, providing computing data specifically for nuclear engineering laboratories, which can be accurate to 656 digits after the decimal point, greatly saving manpower computing and various R&D costs, and improving R&D speed.

The computer separated the uranium series isotopes in the centrifuge, which enabled the Tang Empire to obtain a kilogram of fissile enriched uranium with a purity of 87% for the first time in June 1939.

Although Zhang Meng did not understand the detailed manufacturing process of the atomic bomb, he knew the principle. He informed scientists such as Tesla that as long as the enriched uranium reaches more than 90%, it is a weapon-level atomic bomb. At that time, as long as the enriched uranium is pushed to the critical point, it can be directly detonated.

This principle is known to elementary school students in later generations, but in this era, unless someone informs it, even the top scientists would have to spend more than ten years experimenting tens of thousands of times like headless flies before they could be summarized.

Zhang Meng's point-up undoubtedly pointed out the direction for scientists, greatly accelerating the development speed of atomic bombs.

In June 1940, the Tang Empire completed the chain reaction test of small-equivalent enriched uranium critical point in the laboratory and was successful.

When the large-scale Battle of Stalingrad broke out on the Soviet-German battlefield again, the Tang army had already begun to prepare materials according to the requirements of the nuclear R&D team and secretly manufacture weapon-grade atomic bombs.
