The Tang Empire's nuclear shiyan and the detonation of the atomic bomb were not announced to the outside world, and because it was a nuclear shiyan on an uninhabited island in the South Pacific, it was difficult for the outside world to obtain valuable information.

While the Tang Army is vigorously developing nuclear weapons on its own, it is obstructing other countries from acquiring nuclear weapons, and the military's intelligence agents and the National Security Agency are solely responsible for it.

At this time, the agents of the Tang Empire were all over Shijie, especially focusing on infiltrating the three countries of the United States, Germany and the Soviet Union, although the Soviet Union had not developed any signs of nuclear weapons at this time, but the Tang Empire took precautions, and with the support of Zhang Meng, it was early to discharge spies into various departments within the Soviet Union and lurk, and some had been lurking for eight years.

Both the United States and Germany are developing atomic bombs, which the Tang Empire has intercepted intelligence, but the Tang Dynasty agents rarely make trouble directly, mainly to deliberately leak intelligence to the United States and Germany, the US military and the German army have secretly obtained the Jishu production transfer agreement of long-range strategic bombers from the Tang Empire, and the US military has used this to mass-produce B29 strategic bombers to bomb the German mainland and destroy the German atomic bomb research and development base. The German army developed and produced the Junkers Type 390 strategic bomber based on the related jishu of the Datang Great White Crane strategic bomber, and began to retaliate against the United States, and also bombed the US military atomic bomb research and development base in Manhattan, killing more than 6,000 scientists involved in the development of the atomic bomb and dealing heavy damage to the US atomic bomb project.

Hoover was so angry that he vomited blood, Manhattan Jihua didn't even know the vice president, the location was extremely secretive, how did the Germans know such an accurate address.

In contrast, US strategic bombers can quickly fly to the German mainland to bomb with the help of North Africa. Bombers take off every day. German bombers, on the other hand, had to cross the Atlantic to bomb the continental United States, and it would be nice to be able to take off once a week.

However, the daily bombing of the German mainland by the US military caused panic to the Germans. But it was far less serious than the panic caused by the German bombing of the American mainland once a week.

Unlike the Germans, who grew up in the war, Americans have been at peace for too long and are more afraid of war and sacrifice.

However, the Germans were not having a good time, as the US military took control of North Africa and prepared to land on the European continent from southern Europe, which put huge military pressure on the German army. Meanwhile. On the Soviet battlefield, the Germans suffered heavy losses after the defeat in the Second Battle of Stalingrad. The Soviets switched to a counteroffensive, leaving the Germans struggling to defend.

After a few years of glorious victories in the war, the Germans gradually turned from the initial excitement to reality, and the war did not bring any substantial changes to their lives. Instead, they are getting poorer and poorer. The nationalist agitation that supported Hitler at the beginning of the war. Soon crushed by the cruel reality of life.

With the defeat of the Soviet battlefield, the Germans' depressed mood became stronger and stronger, and the supply of troops became more and more tight, only 20 years between the two Shijie wars, and a generation of Germans grew up and soon died out in World War II, and Germany itself was also facing the depletion of troops, and it had to defend most of Europe, and the strength was tight.

The U.S. military was not worried about the German invasion of the U.S. mainland. And the United States was affected by the economic crisis, and a large number of unemployed people happened to be conscripted to fight. The U.S. forces were well stocked and assembled in North Africa, preparing to land on the Italian Peninsula or the Greek Peninsula.

In the Pacific, with the expiration of the ten-year period of the first phase of the US-Tang non-aggression pact, the Americans were very nervous and did not know whether the Tang Empire would renew the treaty, and once it was not renewed, it would mean that the Tang Empire was ready to go to war against the United States.

The U.S. Navy is worried about this by concentrating half of the sea liliang in Pearl Harbor in the Pacific Ocean.

However, to their delight, the Tang Empire agreed to renew the treaty, and on August 3, 1942, Zhang Meng and Hoover signed a renewal of the non-aggression pact between the United States and Tang in Chang'an, which was extended for another ten years. Last time, Zhang Meng took the initiative to go to Washington to sign the treaty, and this time the president of the United States personally rushed to Chang'an to sign the treaty.

As the United States and Tang renewed the non-aggression pact again, the Americans were relieved, and the main fleet of the US Navy began to withdraw from the Pearl Harbor base in the Pacific Ocean and turned to the Mediterranean Sea to prepare for a decisive battle with the German High Seas Fleet and land in Europe.

On the other hand, after hearing that the United States and Tang had renewed the treaty, Hitler was dumbfounded, knowing that the Tang Empire had abandoned the German-Italian alliance, and was obviously not optimistic that Germany and Italy would be able to win the war.

Hitler was annoyed and really wanted to declare war on the Tang Empire immediately, but he quickly calmed down. At present, the German army can still insist that most of the steel and fuel required for tanks, warships, and aircraft are supplied by the Tang Empire, and it is the Tang Empire that provides it to the German army under pressure from the United States in order to make money.

At that time, Hitler was worried that the United States would enter the war to help Britain, and did not dare to order submarines to attack American ships. Now it is the opposite, the US military knows that the merchant ships of the Tang Empire have entered the island of Ireland, Gibraltar under the Tang Dynasty, Cyprus under the Tang Dynasty and other places, and resold the materials to Germany and Italy, but they do not dare to attack the merchant ships of the Tang Dynasty, the reason is the same, they are worried about the huge war machine of the Tang Empire.

Hitler endured it, but he knew that it wouldn't last long, because the gold and silver reserves in his hand to pay for the Tang Empire were not much, and once he had no money to pay, the Tang Empire would inevitably fall into the well without hesitation.

Hitler was so sad that he decided to step up the development of the atomic bomb as a counterattack weapon for Zuihou.

On February 3, 1943, the main fleet of the U.S. Navy, which had just arrived in the North Atlantic, was suddenly attacked by the German High Seas Fleet.

This is after the Battle of Jutland in World War I, the largest naval battle broke out in World War II, the German Navy Jihua took advantage of the exhaustion of the US Navy from afar to annihilate or hit it in one fell swoop, the overall strength of the US Navy is stronger than the German High Seas Fleet, the number of aircraft carriers in the main battleship is five more, two more super battleships, and other warships are basically the same as the German army, although the German army took the lead in launching a surprise attack, inflicting heavy losses on the US military, but the US military then counterattacked, and also caused heavy losses to the German high seas fleet.

The two sides fought fiercely for three days and three nights, and Zuihou took the initiative to evacuate because of the shortage of ammunition.

In the end, the German High Seas Fleet lost 4 aircraft carriers, 3 battleships, 3 heavy cruisers, 47 destroyers and 5 submarines, 327 aircraft, and 12,000 casualties.

And the US Navy did not have a good time, losing 5 aircraft carriers, 4 battleships, 1 heavy cruiser and 28 destroyers, 229 aircraft, and 11,000 casualties.

Most of the German warships were sunk by US carrier-based aircraft, and most of the US warships were sunk by German submarines, and the losses on both sides were very heavy, but it is clear that the German army is still using submarine attack tactics, but the US military is following the example of the Tang Army and focusing on the use of aircraft carrier battle groups.

After the Battle of the Atlantic, the German High Seas Fleet was in a hurry to return to its home port for repairs, but the US Navy was too far away from the mainland and simply did not repair it, but instead seized the opportunity to seize the sea supremacy in the Mediterranean, cover the landing of US troops on the Italian Peninsula, and gain the strategic initiative.
