April was supposed to be a sunny April, but it was no different for a place where the weather seemed to be the same all year round, the same hot as a steamer during the day and cold as an ice cellar at night, and the same dripping water as expensive as oil. This is Lop Nur, a place known as the forbidden area of life, and it is also a place that Su Tong believes can make Huaxia bloom again.

In this originally barren wasteland, there are countless dense tents and uneven buildings from far to near, and countless soldiers wearing yellow desert security clothing are constantly piercing the edges, including many scholars in white coats.

In a building buried more than ten meters underground, Zhang Zizhong was standing next to a middle-aged man about forty years old with a pair of black-rimmed glasses, his expression with a hint of imperceptible tension and solemnity.

The middle-aged man lifted his eyes on his nose, and said in a slightly excited tone: "Commander Zhang, just now the assembly room reported that the No. 1 bomb has been assembled and can be tested at any time, and our efforts have finally paid off!" "Brother Bingqiong, this explosion test is related to our hard work in the past two years, it also pins high hopes on the president, and more importantly, it is related to the future of our country, but there must be no mistakes. ..., Zhang Zizhong was not as happy as this middle-aged man, but was a little worried on the side, "In the past two years, the country here alone has invested up to a billion gold yuan coupons, but it is not for us to play around, if there is a slight difference in the pool, we are the sinners of the country!" Qian Bingqiong nodded: "I don't know what you said, but you must know that we are engaged in science and technology, and there is no 100% success rate in science, but as long as there is such a glimmer of possibility, it is worth the efforts of us scientific research workers, and we already have a complete theory and production steps, according to our calculations, the success rate of this explosion has reached more than 90%, which is already quite an amazing probability of success." Zhang Zizhong said with some embarrassment: "Mr. Qian, you also know that I am a soldier, and I don't know much about the high-tech you are engaged in. Qian Bingqiong said solemnly: "No, you have done a very good job, nearly 700 days and nights in the past two years, we who are engaged in scientific research can devote ourselves to our work with such peace of mind, you are indispensable, it can be said that if we want to do all this in just two years without your efforts, it is impossible." Zhang Zizhong smiled, "Okay, let's not praise each other here, whether the hard work of the past two years has been in vain or not, it will be clear after the test explosion tomorrow, now let's go to the equipment workshop together to see." "Good!" Qian Bingqiong nodded happily and walked towards another place underground with Zhang Zizhong.

There is a building complex more than 500 meters away from the ground bunker, this building complex is very large, covering an area of nearly 100,000 square meters, two years ago there were almost no tall trees in the entire base here, there were low desert plants everywhere, the road did not even have time to pave oil, the roadside was littered with building materials, cranes, rollers, and trucks drove by indiscriminately, and there was a mess everywhere.

Now, two years later, it has become a city of more than 60,000 people, a city that you will never find on the maps published in China, it is a place that does not exist to the outside world, this is the base of Lop Nur, the whole city is isolated by barbed wire, patrol cars and patrol helicopters, and for the residents who live in the city, this base is all they have to live.

Anyone who wants to enter this base must show a pass to the security forces on duty here, and only those with a certificate jointly issued by the Ministry of Defense and the Huaxia Institute of Physics can enter, and all people who enter this base can only use your pseudonym, and there is only one principle of "secrecy"! This is also the only principle of the city.

In a large workshop, Qian Xuesen, dressed in a white coat, was discussing something with a group of middle-aged scientific and technological personnel.

"No, the calculations have proved that the first method of explosion is too risky, and the effect of the explosion is extremely unstable, obviously the second option is very good, why do you still want to carry out the first method of explosion on the second bomb? Qian Xuesen's voice was very loud and eager, and it could be seen that his mood was not very calm.

"But Professor Qian, since both methods of explosion can theoretically be successful, why don't we try them one by one? Even if the experiment is not successful, we can accumulate valuable data. A younger technician retorted.

Qian Xuesen shook his head: "No, this is too much of a waste of time, you must know that our time is very precious, don't you know the current situation of our country?" We don't need such an effective method, why use a complicated and laborious method! ”

"Yo, what are you arguing about, can you let me listen to it?" Just as they were arguing, Zhang Zizhong and Qian Bingqiong walked in.

"Commander Zhang, Mr. Qian, you are also here, we are arguing whether to test both explosion methods." It seems that Zhang Zizhong and Qian Bingqiong came over, and Qian Xuesen and the young scientific and technological personnel stopped arguing with some embarrassment.

It turned out that Qian Xuesen and the others were discussing what method to use to detonate the second bomb in case the test of the No. 1 bomb failed tomorrow. Now after demonstration and from the information given by Su Tong, it is concluded that there are two explosion methods, the simpler method is to directly squeeze a piece of fissile material into another piece, this degree should be very fast, according to the calculation results, the explosion speed must reach one ten-thousandth of a second, otherwise the vast majority of fission materials will produce a small-scale explosion before the reaction, wasting the rest of the charge. Another method is to direct the explosion direction of ordinary high explosives to a certain mass of fission material, and the fissile material will be squeezed into a very dense state, because the critical mass of the fission material is approximately proportional to the reciprocal of its conspiracy square, the greater the density, the smaller the critical mass, so that the fission material in the subcritical state will be compressed to the critical state, so that the chain reaction.

These two methods have their own advantages, the first method seems simple and easy to operate, but its biggest disadvantage is that it may waste a lot of energy when exploding, and it is difficult to control, this method requires extremely mature experience and skills, and the miniaturization of nuclear bombs in later generations is used in this way to detonate. The second method of explosion may appear to be more cumbersome than the first method on the surface, but it has the advantage of not wasting energy easily, which was also the method commonly used in early atomic bombs. What Qian Xuesen and those scientific and technological personnel were arguing about just now was the pros and cons of these two methods.

"Okay, I don't think there's any point in arguing now, you must know that the most important thing for us now is to gain time, how to complete this nuclear test within the specified time with quality and quantity is the most urgent issue we have now, as for the quality and badness of the two methods you just said, since I am a layman, it is not easy to comment on it, but I want to say that there are different opinions, which can be left for later discussion slowly, this matter is related to the life and death of our country, everyone must be cautious and cautious." Zhang Zizhong, as the top leader of the base, made a decision, and everyone stopped arguing.

Although Zhang Zizhong criticized these young scientific researchers, he admired them very much in his heart, they were all excellent professors and college students drawn from various mathematics departments in universities all over the country, and when these professors and students entered here, they were equivalent to losing their freedom, completely disappearing from the world of their relatives and friends, and they lived a life of isolation and carried out all kinds of boring research and experiments day and night. Despite this, none of them complained, because they all knew that this was an experiment that was closely related to the life and death of the country, and Zhang Zizhong was full of respect for these scientific researchers from the bottom of his heart.

Accompanied by technicians, Zhang Zizhong and Qian Bingqiong came to the core of the base, that is, the nuclear explosion laboratory, which is mainly for research and manufacturing of high-performance implosion systems, which is one of the most important laboratories inside the base in addition to refining sodium and extracting heavy water.

In the test strength, Zhang Zizhong observed that dozens of explosive lens cups were stacked around the core of the explosion, just like a football, so that a larger surface area could be guaranteed.

The entire sphere is placed on a platinum mesh, and each half of the implosion system has thirty-two longitudinal irregular Lou-shaped blast lenses. Looking at this cup-shaped object, Zhang Zizhong knew that he didn't know much about what they were studying, and all he did for them was logistics and security work, Zhang Zizhong once said: "As long as it is beneficial to the project, they want a ladder that can climb to the moon, and I will try my best to help them get it." …，

Looking at the results of countless scientific research workers in the past two years, Zhang Zizhong muttered: "The research has finally come to fruition, and the president will definitely be very happy, right?" Listening to Zhang Zizhong's excited tone on the phone, half of the big stone in Su Tong's heart finally fell to the ground, and the other half had to wait until tomorrow to explode before it could really fall. Feeling this, Su Tong sneered at what terrorists have successfully built their own nuclear bombs using the manufacturing technology circulating on the Internet, looking at the history of the development of nuclear weapons in various countries around the world, that country does not gather the elites of all industries in the country and conduct research and experiments under the unified command of the country to successfully develop them, after all, human energy is limited, even if terrorists hold a small group of scientists hostage to develop nuclear weapons for them, But without the support of a country's huge manpower and material resources, if you want to develop it successfully, you can't even be possessed by God. Even if it is to build an aircraft carrier, it took more than half a century for later Huaxia to launch the first aircraft carrier, and it is still a second-hand purchase, not to mention a nuclear weapon that is more complex than an aircraft carrier.

For example, in order to mine enough sodium, Su Tong had to order the mobilization of thousands of death row prisoners to dig in Siberia and other parts of the country, most of whom are now no longer alive. Historically, because the Americans did not have enough copper, in order to make enough electromagnetic separation devices to isolate enough sodium, they had to mobilize a total of 80,000 tons of silver to enter the emergency.

It can be seen that the United States, Britain, France, Russia and other countries are truly nuclear states. As for the nuclear weapons of India, Pakistan and other countries, they are just children's toys.

At four o'clock in the morning on April 20, 1942, the core of the atomic bomb had been installed around the world. All components, including the blast prism, castings, neutron reflectors, sodium cores, ignition devices, and electronic components, have been delivered to the test site 200 kilometers away from the base under the command of engineers.

Qian Bingqiong, chief designer of the project, and Zhang Zizhong, commander of the base, personally came to the scene, and at the site of the test explosion, the engineers had already installed a tall iron tower more than 100 meters high, where the world's first atomic bomb was about to be planted. In the endless wasteland around the tower, various test objects are placed at different distances around the tower. Cows, sheep, horses, donkeys, pigs, dogs,

Chickens, ducks, monkeys, orangutans, and more eat quietly in iron cages.

In the reinforced concrete structure on the ground, the staff has also installed various detection instruments and photographic facilities to collect various scientific data. There are also planes, artillery, tanks,

Large warships and other models, all of which were built by the hard work of the engineering troops in the past two years, but they didn't know that the ultimate goal of all these things they worked hard to build in two years was to destroy!

In the underground bunker, Zhang Zizhong had never felt that the phone in his hand was so heavy, he gasped and said softly to the phone: "President, the goods have arrived at the scene and are ready!" "Let's get started!" There was also a fluttering but wheezing voice on the phone.

"Yes!" Zhang Zizhong put down the phone, turned his head to Qian Bingqiong beside him and said, "Start installing!" "Start installing the lifting! ..., Qian Bingqiong ordered loudly to the staff around him.

With an order, the crane placed on the top of the tower slowly began to transport all the components upwards, and hundreds of workers wearing white chemical protective suits began the intense installation work. At this time, the desert temperature was as high as 42 degrees Celsius, and the sins suffered by these workers wearing sealed chemical protective suits can be imagined, but at this time, no one made unnecessary noise, and everyone was working silently and nervously.

At 4:20 p.m., the first atomic bomb in human history was assembled.

After receiving the report, Su Tong felt that his breathing was a little short, and even his palms kept sweating. He asked Qian Bingqiong over the phone, "Are you sure that this thing will definitely explode?" The other end of the phone was silent for a moment before he said lightly: "In terms of probability, there is a great certainty of success." …，

"That means there's a chance of unsuccessful." Su Tong's heart beat a few times, in two years, the direct investment of one billion gold yuan coupons, as well as indirect personnel, equipment and materials in all aspects, to calculate the investment of at least billions of gold yuan coupons in the past two years, if these things are lost, then the blow to Su Tong and all the staff is huge.

"President, everything is ready to detonate!" At 4:37 p.m., Qian Bingqiong's voice came from the phone.

"That'...... Let's get started! Su Tong felt that his throat was smoking, looking at the round guy standing high on the iron tower, Qian Bingqiong, who was the commander-in-chief of the scene, ordered: "Start evacuating!" After the order, the last dozens of guards and more than 20 staff members left the scene in more than a dozen jeeps and drove towards the underground bunker dozens of kilometers away.

In the bunker below, Zhang Zizhong gently said to Qian Bingqiong beside him: "Mr. Qian, you come and twist." …，

Qian Bingqiong nodded silently, stretched out his hand and pulled the main transmitter switch hard, and then started the second and third stage transmitters, and the current signal was transmitted to the timing detonator on the big iron tower, and people began to calculate the time nervously.

In the ten seconds of waiting, Zhang Zizhong felt that the time was so long, and the air in the underground bunker was so tense that it seemed to be about to condense.

"Toot toot, ding" As the timer rang out, a loud rumbling sound came quickly from far to near.

A bright huge fireball lit up in the distance, rolling up smoke and dust on the ground, the heat wave rolled, the fire scorched, and a bright light dozens of times brighter than the sun rose into the sky.

The atmosphere was suddenly inflated by tens of millions of degrees of heat and the huge heat caused by the flames of light, and the wind swept the land invincible, followed by bursts of loud noises and continuous roars, and then the powerful impact bō spread rapidly across the field, thunder and thunder, and the autumn wind swept away the leaves to destroy everything in its path. The flames were wrapped in smoke and dust together with the red air mass produced by the molten soil, rising into the air, rising to an altitude of more than 400 meters, and the rolling dark red clouds and flames gradually formed a huge mushroom-shaped cloud of smoke and fire, and the mushroom cloud continued to rise and expand into the sky, and then a B-port heavy bomber flew in the distance, which will go deep into the explosion scene for sampling.

Tens of thousands of officers and soldiers and scientific research workers who witnessed this scene on a hillside dozens of kilometers away could not believe their eyes after watching this scene.

Liu Shibin, a researcher who returned from studying in the United States, later wrote in his diary: It is the most beautiful scenery I have ever seen in my life, and the red clouds rose to a height of more than 400 meters in less than two seconds, illuminating the earth and the surrounding sky transparently, and even wearing dark sunglasses to protect the eyes can feel its incomparably hot brightness. A huge fireball with a diameter of about two kilometers rushed straight into the sky, its color constantly changing, from deep purple to orange-yellow, and then spreading and growing, it seemed to be the power of the gods. Yes, only God has this power, as God cried out in Genesis, "Let there be light."

Not to mention those researchers and ordinary soldiers, even Zhang Zizhong, the commander of the base, who has always shown himself with a serious image, couldn't help but sigh later: "The brilliance of that moment pierced the sky, even if I looked through the observation mirror sticking out of the underground bunker, I could still feel the thrilling shock." I can't describe the beauty of the golden, yellow, and purple light that rose into the sky, and only a few seconds after the explosion, the ensuing impact and the massive sound that shook even though I was hiding deep in the underground bunker. The roar of this demon we created is as if it were prophesying the end of the world! Unlike Zhang Zizhong, the researchers around him threw themselves into intense work without appreciating this cruel and beautiful scene.

Qian Bingqiong came to him with the final calculation result, took a long breath and said: "The explosion yield this time is about 400,000 tons, of course, this is only the initial calculation result, and the specific data will not come out until tomorrow." "On April 22, 1942, in a small screening room of the Presidential Palace in Nanjing, a fireball suddenly jumped from the top of the tower into the air, the earth suddenly thick smoke billowing and heat waves soared into the sky, the fireball in the air jumped higher and higher straight into the sky, as far as the eye could see, a huge pillar of fire jumped up against the smoke cloud, the height exceeded 10,000 meters, and in less than a few seconds the air transformed into a huge mushroom cloud.

Cows, sheep, pigs and dogs and other livestock near the tower were vaporized in an instant, dozens of tons of tanks and sturdy buildings flew like toys and blew away in an instant, and the sky instantly turned into the same color, shining brighter than the sun!

Su Tong, Jiang Baili, Na Chongxi, Li Zhongren, Vice President Jiang and other important state leaders all looked at this scene dumbfounded, and they were speechless one by one. The huge mushroom clouds on the screen, the weapons and equipment that were destroyed and twisted into scrap metal, the close-up of the plane's pot méng skin melting instantly, the desert around the blast heart being stamped into a saucer-like terrain by huge pressure, and the sand within a radius of several hundred meters melted and formed a layer of jade-like emerald green hard glassy objects, etc., all shocked their hearts.

Bai Chongxi asked with a somewhat sluggish expression: "Jianming, do we still need to fight if we have this thing?" Who can stand it if it goes down? Su Tong smiled mysteriously, "No, on the contrary, our real war has just begun!" ”！。
