On the dock in Nan'anju, the commander and overseer of the Jinwu Right Guard, the commander and overseer of the Yulin Right Guard, and the overseer of the New Element Engineering Garrison and Experimental Force, Zhu Zhaoxie, briefly met together.

In the presence of Zhu Zhaoxie, Yulin Youwei explained the purpose of the mission to Jinwu Zuwei and informed him of the main items he carried.

The most important thing is a total of six atomic fission energy bombs, simply called "atomic bombs", codenamed "tea eggs".

According to the classification of Zhu Jingyuan's previous life, these six atomic bombs were all implosion-type atomic bombs.

Similar to "Fatty" and "Miss Qiu", the overall appearance is round, so the code name has become Tea Egg.

Because Daming had Zhu Jingyuan's guidance, among the two basic design options of the atomic bomb, the gun bullet and the implosion projectile, the Ming directly chose the more complex but more efficient implosion bomb.

Instead of exploring the deep logic of atomic fission, it is simply explained from the basic fission principle.

Nuclear fuel has a critical mass.

If the mass of nuclear fuel that is gathered together exceeds the critical mass in its natural state, atomic fission will naturally occur inside.

This in turn releases an unusually large amount of energy, which is called a nuclear explosion.

However, this critical mass is not unique, there is a critical mass in the natural state, and there is a critical mass in a special environment.

The design idea of the gun bullet is to use the critical mass in the natural state.

The nuclear fuel exceeding the critical mass is divided into two parts and placed at the ends of the barrel resembling a closed barrel.

The nuclear fuel at one end is made into a sphere with a round hole in the middle, and the nuclear fuel at the other end is made into a cylinder that fits the size of the round hole of the sphere.

Chemical explosives are placed behind cylindrical nuclear fuel and detonated when fired.

The practical effect at that time was similar to that of artillery firing shells.

The chemical explosive is used as a propellant, and the combustion instantly generates a huge gas pressure, pushing the nuclear fuel cylinder forward and flying out.

Slam into the hole in the middle of the opposite ball of nuclear fuel.

In this way, the two pieces of nuclear fuel fit together, and the total mass exceeds the critical mass in the natural state.

And so the simplest atomic fission nuclear explosion took place.

The principle is simple and crude, and it is very easy to implement.

Only a portion of the chemical fuel needs to be controlled to explode, which is highly similar to the process of firing ammunition from a traditional gun.

It's like hitting rivets with a hammer again.

Originally, the first bullet in the United States was the "Little Boy", which was shaped like a short, thick cylinder that was completely enclosed.

Due to the urgency of the situation, the United States had to try to prevent Red Lucia from directly participating in the Japanese battlefield.

Therefore, the "little boy" with a simple principle did not do an explosion experiment, but directly used it in actual combat.

The shortcomings of the gun-type atomic bomb are also obvious.

In total, the nuclear fuel is divided into two parts, or two large lumps.

The purpose of the propellant is simply to push the two lumps of fuel together, and the explosion is almost entirely dependent on nuclear fission triggered by the natural critical state.

So to create a gun-type atomic bomb, the total mass of nuclear fuel used must exceed its natural critical mass.

Once fission inside the fuel occurs, the fuel sphere will be blown apart.

The quality decreases, and the nuclear fission can no longer be maintained.

So the vast majority of the nuclear fuel of the gun atomic bomb will be wasted.

The critical mass of uranium in its natural state was forty-eight kilograms, and the American "little boy" loaded fifty-one kilograms of uranium two-three-five.

In the end, only about 1.5 percent of the mass, or 765 grams, was fissioned.

In total, the equivalent of fifteen thousand tons of standard explosives was released.

Most of the others have turned into residue.

The design idea of an implosion atomic bomb is to divide the nuclear fuel into many parts and arrange them on the inner surface of the spherical shell.

Behind every piece of nuclear fuel, a piece of chemical explosives must be installed.

When this atomic bomb is detonated, all chemical explosives are exploded at the same time, and all nuclear fuel is pushed to the center of the sphere at the same time.

This makes it possible to use the thrust provided by the propellant to increase the pressure on the nuclear fuel that is concentrated in the center of the sphere.

Preventing the energy of a nuclear explosion from spreading outward immediately allows the fission reaction to last as little as possible.

This is actually the principle of a conventional bomb explosion.

The fuel burns in a closed environment, and the tremendous pressure generated by the expansion of the gas breaks apart the shells in which it is located.

The internal combustion will continue until the shell splits.

Although this time is still very short in human perception, it has increased by "very long" compared to the natural open state of combustion.

More critically, this pressure also compresses the distance between the nucleus and the neutron, thereby increasing the probability of the neutron hitting the nucleus.

Based on these principles, the weight of the nuclear fuel used in the implosion bomb can be lower than the critical mass of the nuclear fuel in its natural state.

The critical mass of plutonium in its natural state is sixteen kilograms, but the American "fat man" only holds 6.2 kilograms of plutonium-239.

Eventually, about 20 percent of the mass, or 1.24 kilograms of plutonium, fissioned.

The result was an energy equivalent to 20,000 tons of standard explosives.

The advantages of an implosion nuclear bomb are obvious, and the disadvantages or difficulties are certainly obvious.

The key is to allow the dispersed nuclear fuel, which is pushed by the explosives to the center of the sphere, as close as possible.

According to the experience of the United States, the difference in the time of detonation of explosives cannot exceed seven milliseconds.

This requires sufficient computing precision to know how to design and arrange and control the entire system.

The size and curvature of the spherical shell, the distance and block scheme of the nuclear fuel, the mass of the fuse and the energy released.

Second, it requires a sufficient level of technology to achieve and ensure that all nuclear fuel can be aggregated within seven seconds.

The quality of the explosives and fuses should be stable enough, the shell of the sphere should be uniform and strong enough, and the division and installation of nuclear fuel should be precise enough.

The most basic requirement is that traditional chemical fuses are not sufficient, at least electronic detonators.

The United States was worried about whether this design would really succeed, so it first interviewed one in the desert of its homeland.

Implosion atomic bomb albeit with difficulty.

However, under the level of technology and craftsmanship after World War II, it was not too difficult for the big countries at that time.

And this design idea can continue to be optimized.

Continue to reduce the charge, continue to reduce the size and weight of the atomic bomb, from a few thousand kilograms to several tens of kilograms, which can be carried directly by one person.

The implosion atomic bomb can be considered the basis for the miniaturization of nuclear weapons.

The first "fat man" in the United States weighed more than 4,500 kilograms and had an explosive yield of 20,000 tons.

Miss Qiu weighed only 1,500 kilograms, but the explosive yield was 30,000 tons.

Because from the very beginning, Ms. Qiu knew that she had to optimize the weight in the right direction.

Daming also has Zhu Jingyuan's experience, and the project management method is similar.

Daming's new element project went straight to the implosion atomic bomb from the beginning.

The situation related to gun ammunition only appeared in the theoretical research stage, and did not enter the actual design and production stage.

Now the weight of this batch of "tea eggs" newly baked in Daming is directly controlled within two tons.

Daming's existing light carrier-based attack aircraft can be moved.

In other words, as soon as they are born, they already have a strong practical significance.

Before 1953, the MK4 atomic bomb in service with the United States could only be regarded as an optimized version of the "Fat Man".

The throwing weight was up to 4,900 kilograms and could only be carried by the B29 bombers of that time.

A total of about 550 MK4 atomic bombs were produced, and only 35 B29 bombers on strategic duty were produced.

Before 1953, the atomic bombs of the United States actually had relatively limited actual combat capabilities.

At that time, they could only be used against small and medium-sized countries such as Japan.

For a large country like Red Lucia and Seris, these atomic weapons and vehicles are powerless.

Once used in war, it will drag the situation to an irreparable situation.

So in the war on the Goryeo Peninsula, they actually didn't dare to use it.

The weight of the MK5 atomic bomb, which was put into service in 1952, was reduced to less than 1,500 kilograms, and its actual combat capability was greatly enhanced.

Daming's "tea eggs" are already close to the level of the fifties in the United States.

Of course, the most important issue is to make sure that they can really explode normally.

The personnel of the Habayashi Right Guard, who escorted the "Tea Eggs", completed the briefing with the Kingo Right Guard, who was in charge of port management.

The four dedicated cargo compartments for the "tea eggs" were then left on board.

The two warehouses were carefully transferred and loaded onto a special transport train inside the terminal.

Each "tea egg" weighs only two tons, but it is arranged separately in a specially designed container.

The right guard of Yubayashi left a part of the personnel and continued to guard the docks and boats.

Another part of the personnel accompanied Zhu Zhaoxie to board the "tea egg special car" and escorted the two tea eggs to the inland test site to "boil eggs".

The train maintained a speed of sixty kilometers per hour and headed towards the interior of the Tiannan continent.

The scene on both sides of the railway slowly transitions from the humid forest area along the coast to the sparse wasteland and finally into the desolate Gobi Desert.

Daming's most important uranium mine in the Tiannan Continent is also next to this railway.

The mined ore is also transported from this railway to the port, and then loaded onto ships for use in Xintianfu.

After passing through the mine, the train traveled more than eight kilometers in the desert.

In the end, we arrived at the inland location of nearly 1,000 kilometers away from the port of Nananzhou, very close to the most central location of the entire Tiannan continent.

In this most vast desert, there is a lonely building.

This is not the official station of the Yulin Left Guard, but a cutting-edge test command center.

Before the arrival of the train, Yulin Zuowei had received an advance notice, and the relevant personnel had made preparations before the test explosion.

When the train arrived, the test command center was already full of murder.

Soldiers in full costume were on duty at various key positions, and the relevant craftsmen in charge of testing were also waiting at their posts.

Under the witness of Zhu Zhaoxie, the Yulin right guard, who escorted the "tea eggs", completed the handover with the Yulin left guard stationed in the command center.

The craftsmen opened the container in which the "tea eggs" were transported and examined the cargo itself very carefully.

After confirming that all conditions are normal, the base remains on alert.

Yubayashi Zuowei parked one tea egg in the experimental center, and the other was loaded on a special off-road truck.

A group of guards escorted a group of craftsmen and followed the truck in other buses to the ground test site two hundred kilometers northwest of the command center.

Zhu Zhaoxie also went with the test team, and he had to personally participate in all the test tasks so that he could report to Zhu Jingyuan.

The first atomic bomb will be detonated on a specialized test bench.

The test bench is a specially built iron tower, with a height of one hundred and eight meters, which is the "stove" for boiling "tea eggs".

The convoy arrived at the test site and rested for the day, while confirming the wind direction and climate information for the previous days at the site, as well as an assessment of the coming days.

The tea eggs and the personnel and equipment on site are inspected again, and the "tea eggs" are hoisted onto the "stove rack".

After the tea egg hoisting was completed, all the control lines were connected, and the observation and recording equipment was debugged, most of the day had passed.

After Zhu Zhaoxie finished all the work, he personally took a telegram in the afternoon of the same day to explain the situation to the Ming Emperor.

After receiving the message, Emperor Zhu Jingyuan of the Ming Dynasty replied simply:

"Now that the stove is ready, let's put it in the pot early tomorrow morning, remember to simmer slowly, don't worry."

After the morning of the next day, Zhu Jingyuan went directly to his grandfather Zhu Zhongliang's residence.

Zhu Zhongliang is eighty years old this year, and he will be regarded as a real old man in the next generation, and he will already be regarded as a birthday star in this era.

Zhu Zhongliang, as the former emperor of the Ming Dynasty, has had proper exercise and maintenance since he was a child.

The body is much better than the average person, much better than George III, and the mental state has always been very good, and the desire to survive is very strong.

With the continuous improvement of medical treatment at night, diseases that were difficult to treat in the past can now be solved.

Zhu Zhongliang's body is still quite strong now, although he can no longer run around like he did when he was sixty or seventy years old.

But it's still perfectly fine to move around the yard and around the yard on your own, or to take a short trip by car.

When Zhu Jingyuan saw Zhu Zhongliang, the old man was walking in the courtyard.

Zhu Jingyuan subconsciously wanted to help, and the old man subconsciously wanted to get rid of it, wanting to show that he could go by himself.

But this thought disappeared in a flash, and Zhu Jingyuan held his arm:

"Is there any good news for coming to grandpa so early?"

Zhu Jingyuan said with a smile:

"The tea eggs are in the pot."

Zhu Zhongliang's eyes widened suddenly:

"Really!"

Zhu Jingyuan nodded lightly:

"I've got them on fire, and whether it succeeds or not, there will be news today."

Zhu Zhongliang let out a long breath, shook his head and muttered:

"Finally waited for this day, finally waited for this day, did you tell your father?"

Zhu Jingyuan said:

"I'll have to tell you first, and then I'll go to Daddy......"

Zhu Zhongliang subconsciously wanted to let Zhu Jingyuan pass, but when the words came to his lips, he changed his words:

"I'll call him and ask him to come to me directly, and we'll wait for news together here......"

At the same time, thousands of miles away, on the test ground of the Tiannan Continent.

After Zhu Zhaoxie received Zhu Jingyuan's reply, he began to carry out the experimental task in the early morning of the next day.

Confirm the status of the "Tea Egg" again, the status of the connecting line, and the status of the observation device.

and the state of the test subject used to withstand the explosion.

Around the test bench, at different distances and in different directions, houses of various structures were specially constructed.

Various types of vehicles, various military and civilian machines and equipment, as well as various types of large and small animals are placed.

They are accompanied by a variety of recording and observation equipment, as well as cameras and photographic equipment for continuous work or remote control.

Daming already had early live TV technology, which could transmit the video taken on the spot to the rear through the line.

At nine o'clock in the morning, the final deployment and inspection were completed, and the clearance process began.

All personnel at the scene received an order to retreat.

Inside and outside the forward bunker, sixteen kilometers outside the test site, craftsmen kept an eye on the observation and recording equipment.

There is also a group of special military photographers who will prepare to take pictures of the situation at the test site, including photos and videos.

At 11 a.m., the helicopter inspected the test site and confirmed that there were no remaining personnel within 10 kilometers.

Everything is ready, just waiting for the final detonation order.

This order also has to be given by the Ming Emperor, and no one else has the right to take responsibility.

At twelve o'clock in the afternoon, Zhu Zhaoxie, together with the commander of the Yulin Left Guard and the overseers, hurriedly sent a final telegram to the Jingshi again.

Zhu Jingyuan was having lunch with his grandfather and father, and after receiving the news, he responded directly that he could light a fire.

The order that Zhu Jingyuan replied to was once again confirmed by Zhu Zhaoxie, the commander of the Yulin Left Guard at the scene, and the overseers.

At one o'clock in the afternoon, in an extremely tense atmosphere, the commander pressed the detonation button.
