Before this, although Einstein and other scientists jointly wrote a letter to Truman, opposing the use of atomic bombs.

But on the morning of July 30, 1945, the heads of the United States, Britain and the Soviet Union in Potsdam received a telegram and fax, and Japan officially refused the final report of the allies' surrender clause.

The stubbornness of Japanese militarism aroused strong indignation. Out of protection of the lives of allied soldiers, forced Japan to surrender as soon as possible, and in order to curb the Soviet Union's expansion in the Far East, the United States decided to throw an atomic bomb in Japan to accelerate the war.

In order to ensure the attack effect of the atomic bomb, the United States has specially established a target committee and determined three principles.

First, it must be in the city center;

Second, the city has basically not undergone large-scale bombing;

Third, it is conducive to the atomic bomb shock wave to maximize the killing effect.

After careful research by the military, it decided to choose between Tokyo, Kyoto, Niigata, Okura, Hiroshima and Nagasaki.

There is no way, the United States currently has only 2 atomic bombs.

Kyoto is the ancient cultural capital of Japan, and was excluded for the need for post-war rule;

At the same time, Tokyo has suffered multiple large-scale strategic bombings and has almost been razed to the ground. Apart from specific protected areas, there are no valuable bombing targets.

Tokyo is already a "city of death".

According to the United States, "Dropping the atomic bomb to Tokyo is a pure waste, because it is not easy to assess the damage effect of the atomic bomb."

Niigata is an important aluminum product production base in Japan, but it is excluded from being too far away.

Okura is an important industrial base in Kyushu, Japan, but local weather conditions are also excluded.

Finally, the US military selected the attack targets as Hiroshima and Nagasaki.

Hiroshima is the city of the Japanese Army and is the location of the Second General Army headquarters of Japan's defense. All Japanese troops heading to China, North Korea, Southeast Asia and the South China Sea islands set sail from Hiroshima.

Nagasaki is an important base for Japanese industry, especially shipbuilding.

If you choose the bombing target, it will only be a matter of time before you drop the atomic bomb.

At 7 a.m. on August 6, Allied weather observation aircraft arrived over Hiroshima.

After careful observation, the observation aircraft immediately contacted the Ainora Guy b-29 bomber and reported: "The weather over Hiroshima is good and it fully meets the conditions for bomb dropping."

So, the target of the little boy's atomic bomb was finally determined, which was Hiroshima City.

Woo~Woo~Woo~

But at this moment, a fierce air raid alarm sounded in Hiroshima City, and the Japanese radar station alertly discovered the uninvited guest.

Hiroshima citizens are no longer indifferent to the usual air raid alarms, so few people enter the air raid shelter to hide.

However, what they did not expect was that what they waited for this time was not the regular bombing of the Allied forces, but the "disaster of the world" that made them even regret it.

At 8:9 am, the Enola Guy B-29 bomber approached the city of Guam, and the crew carried out the final preparations and set the aircraft to operate automatically.

After the bomb dropper corrected the target for the last time, the co-pilot Colonel Lewis turned on the bullet-drop safety switch.

At 9:15, Colonel Tibbets finally pressed the bomb drop button, and the atomic bomb was dropped out of the bomb bay.

The timing device was effective at 8:15:17, and the atomic bomb was automatically dropped.

The sky and ground of Hiroshima were very calm. Seeing the three parachutes slowly falling from a high altitude, Hiroshima citizens stopped and watched calmly. They thought that the enemy plane was shot and the pilot parachuted to escape.

Well, until now, most Japanese people are still very confident.

But at this moment, a dazzling light suddenly emanated from the sky, and those who saw it could not tell what color it was.

It was as if the door to time and space was suddenly opened, and a stream of light from another world that could not be seen directly enveloped the entire human world.

In an instant, almost all Hiroshima's clocks stopped.

When the pointer pointed at 9:15, the "Little Boy" atomic bomb exploded 600 meters above the hospital in the southeast of Xiangsheng Bridge after a 43-second flat throwing movement.

A huge fireball formed in the center of the atomic bomb explosion. The thermonuclear fission caused a huge smoke fire to rise within a kilometer range near the explosion center.

The crew wearing special goggles saw a purple-white flash, followed by a deafening explosion, as if the end of the world had arrived.

In an instant, there was a dark gray smoke cloud with a diameter of about 4,800 meters above Hiroshima. A white smoke column rose in the center of the smoke cloud. The smoke cloud formed a mushroom-shaped shape on the top and then left the smoke column.

The top of the smoke column forms a mushroom-shaped shape.

As the first nuclear weapon used against humans in human history, the "Little Boy" atomic bomb is 3 meters long, 71 cm wide, and weighs 4,000 kg.

Using a "gun" design, a hollow cylinder rich in uranium is shot with explosives onto a solid cylinder of the same material, causing a whole piece of supercritical mass of uranium and causing a nuclear chain reaction.

The little boy was equipped with 64 kilograms of uranium-235, less than one kilogram of which underwent nuclear fission, but the energy released was about 13,000 metric tons of TNT intense explosives.

After the atomic bomb explosion, the high temperature of more than 6,000 degrees was generated, turning everything around into ashes. The city with a radius of 42 square kilometers was instantly destroyed, 60,000 houses in the city were destroyed, and the house destruction rate was as high as more than 70%.

More than 90% of victims within 500 meters from the center of the atomic bomb have died on the spot or died on the same day, more than 70% of people within 500 to 1,000 meters have died on the spot or died on the same day, and 50% of those who survive temporarily died within 6 days.

People can still feel the hot air flow 16 kilometers away.

It is generally estimated that about 70,000 people in Hiroshima immediately melted due to high temperatures caused by nuclear explosions, and then the number of deaths due to burns, radiation and related diseases was as high as more than 200,000.

On August 7, 16 hours after Hiroshima was bombed by an atomic bomb, US President Truman officially announced to the world that the United States used an atomic bomb.

He said that the atomic bomb is the basic force that harnesses the universe, and we release it against those who launched wars in the Pacific and urged Japan to surrender unconditionally!

But even so, Japan did not surrender immediately, and believed that the US military had only one atomic bomb, and still placed its hopes on mediation negotiations, and was unwilling to fall into the abyss directly.

After the first atomic bomb was thrown, the United States did not hear the Japanese announce unconditional surrender within three days, so it announced that as long as the risk of fighting against Japan could be reduced, it would be easy to drop a few more atomic bombs.

In fact, this is a bluff because the United States has only this atomic bomb left.

It was 11:02 am on August 9, 1945. After the attack on Hiroshima, the US military carried out a second atomic bomb attack on Japan.

The commando of five b-29 bombers dropped the atomic bomb "fat man" into the center of Nagasaki.

"Fatty" is a plutonium bomb with a length of about 3.6 meters, a diameter of 1.5 meters, a weight of about 4.9 tons, a TNT equivalent of 22,000 tons, and a explosion height of 503 meters.

The corpses left behind after the Nagasaki atomic bomb explosion. The high temperature generated after the atomic bomb explosion caused all the surrounding buildings and animals and plants to be wiped out instantly.

The bombing caused more than 100,000 people of the 230,000 people in Nagasaki City to be killed and lost that day, and 60% of the city's buildings were destroyed.

The Nagasaki atomic bomb became the "last straw that broke the camel's back". A week after the explosion, Japanese Emperor Hirohito announced that he would accept the Potsdam announcement and surrender unconditionally to the Allies.

On September 2, Japan, who was desperate, signed a surrender letter, and World War II ended here!

World War II was a just anti-fascist war, provoked by the Third German Empire, the Kingdom of Italy, and the Japanese fascism, which caused great disaster to the entire human race.

This world war profoundly changed human history and had a profound impact on all levels of human society, including politics, economy, military, diplomacy, culture and technology.

Human war activities have thus moved from blind to self-consciousness, from impetuous to rationality, and from naive to maturity, and human society has since entered a new historical stage.

"Everything has finally settled, and the years of hard work has finally not been in vain. A new era that belongs to the Chinese nation has begun!"

After the signing ceremony, Yang Fan silently left the hustle and bustle auditorium, walked to the gate alone, staring blankly at the distant horizon.

At this moment, Yang Fan was in an extremely complicated mood. He felt sincerely happy and proud of the great victory of the Chinese nation in the War of Resistance Against Japan, but at the same time, everyone was ecstatic and wept with joy, but he also felt extremely empty and lonely.

"I miss my family more during the holidays." When everyone cheered and enjoyed the hard-won happiness, Mr. Yang couldn't help but think of another home in time and space.

This is not "not returning home without wealth or honor, like walking in the night in brocade clothes", but the common sense of human nature that has been suppressed for a long time. Mr. Yang misses homesome too much.

As the saying goes, the heart is like an arrow. Once the gate of emotions is opened, an unstoppable torrent will burst down the dam in an instant, and it will be out of control from now on.

"Dad, mom, sister, are you all okay now?"

"System Master, come out and explain it quickly! Wait online, hurry up!"

"Tell me quickly, can I go back now? No, can we all go back?"

Yang Fan shouted at his own system. He really wanted to take his wife, children, and children back to the world that originally belonged to him, giving his parents a huge surprise.

Of course, if you can only operate in the reverse direction and move your parents and sister into the current time and space, Mr. Yang will definitely be very happy to accept it.

If there is nothing else, the family must be neat and reunited, otherwise wouldn’t it be a demolition of the east wall to repair the west wall?

Well, I believe this little reasonable wish must be a piece of cake in front of my own system that faces every day and every second!
