Is it difficult to make a nuclear bomb? Experts who have studied nuclear physics will probably tell you that if you have materials, it is not difficult to make a dirty bomb by tying together the spherical uranium-235 that has reached a critical mass with iron wire, and creating a chain reaction even if it cannot explode. As for the actual situation, more than 90 percent of the countries have been eliminated due to the material problem alone, and the principle of the nuclear bomb is very simple, but the difficult thing is the technology to control the nuclear bomb, how to detonate the nuclear bomb, how to make the nuclear bomb smoothly produce a chain reaction, how to prevent the nuclear bomb from getting out of control, how to prevent accidents in the production process, and so on.

Therefore, theoretically, the production of nuclear bombs requires the investment of human and financial resources at the national level and the conduct of a large number of experiments.

What Yun Hong had to do was very simple, pick the fruits of the Soviet Union and the United States of America, and then use the alchemy he now has to combine with the data to make a nuclear bomb to deduce nuclear fission. Uranium and plutonium can be extracted and purified from the earth's crust by alchemy, eliminating the difficulty of obtaining materials, and the simplest and crudest way to make a nuclear bomb is to hit another piece with enriched uranium, and the first nuclear weapon in human history, "Little Boy", uses a similar principle. In the memoirs of the first nuclear bombs in the United States of America, it is recorded that the technical difficulty of making an improvised nuclear bomb is theoretically equivalent to making a small-caliber artillery by pumping more than a dozen kilograms of enriched uranium into another 50 kilograms of enriched uranium at a speed of 350 m/s.

The villain in the bottle once made the sun, and the technology of making the sun and the technology of making the atomic bomb are 108,000 miles apart, and the fundamental difference between the two is nuclear fission and nuclear fusion, at least now human beings are not able to make a controllable nuclear fusion reaction.

Alchemy has the incomparable advantage of modern technology, that is, it can easily change the structure of matter from the atomic level, and the purity of the uranium extracted by alchemy is much higher than that of the uranium extracted by modern technology, and it can easily reach the level required by weapons, which can be regarded as directly crossing the most important part of making a nuclear bomb.

·····

Three days later, Yun Hong went to the Black Reef Chamber of Commerce to retrieve the nuclear bomb materials downloaded by Benny from Russia and the United States of America, most of which were experimental data, recording hundreds of thousands of attempts by the two superpowers in nuclear tests, accurately recording the physical model of the nuclear bomb explosion, mathematical data, engineering technology, and so on.

The written record alone is no less than 10 million words, Yun Hong learned Russian with the soldiers of the Moscow Hotel in the world of "Kabaneri in the Iron City", but he can understand the data records of nuclear bomb experiments left by the Soviet Union.

The amount of these experimental data is too much, and when Yun Hong got it back, he immediately threw himself into it, and used these experimental data to deduce it in combination with his own alchemy.

He wondered if he could make a nuclear bomb with alchemy alone.

Soon, Yun Hong indulged in learning for a week, and the deduction progress reached one-tenth of the data, which is terrifying, you must know that these two materials on the production of nuclear bombs are experiments that the two superpowers have invested a lot of national power in decades, and Yun Hong is just one person to digest this knowledge.

After a superficial understanding of the knowledge of nuclear bomb making, Yun Hong had a clear understanding of whether he was capable of making nuclear bomb weapons.

The answer is yes, it is easy to make, but it is difficult to say, the difficulty lies in the existing risks, for example, the radiation problem is the first problem he needs to solve now, how to ensure that he will not be irradiated when making a nuclear bomb.

Robert finally returned after nearly two weeks away from Yunhong, and she looked the same as before her departure, wearing the traditional English maid's dress, and she looked as if she had just returned from a trip. Shen Hua's meeting with her didn't cause any conflict and chaos, originally Robert could leave when he came back to Shen Hua, but she still chose Yun Hong to act with him when he was still in Roanapura.

In the past week or so, there have been no more young people who have come to harass them, mainly because the news of Yunhong's elimination of the remnants of the Colombian gangsters and Shen Hua's elimination of Mike, one of the sharpshooter brothers, has spread, and the remaining few diehards or bounty hunters who are still planning to disappear from this world in a physical sense when Robert also returns.

Yun Hong is a passer-by in Roanapura, and he has not done anything except for the riots caused by Robert, and the Black Reef Chamber of Commerce still accepts all kinds of commissions, and Benny, like Yun Hong, rarely goes out.

Yun Hong spent most of his time studying the knowledge obtained from the two superpowers in the world, and then he would go to the Moscow Hotel to discuss the matter of snatching a nuclear-powered aircraft carrier, the Moscow Hotel had prepared a big ship, and the day before yesterday Yun Hong spent most of the day using alchemy to transform this big ship, not all ships can easily approach the nuclear-powered aircraft carrier, not to mention the intelligence collection system and fighter system of the aircraft carrier itself, the aircraft carrier will inevitably have frigates around.

······

On the beach of Roanapura, it is obviously summer, but the pedestrians near the beach feel a chill inexplicably, and they can't help but hug their bodies and shiver when they are exposed to the sun. The alternation of hot and cold makes even the beach area look eerie in terms of changing climates. The sky is clear, the sea breeze is melodious, and the coldness that peels off the temperature comes out of nowhere.

In the depths of the sea, Yun Hong's body sank to the bottom of the sea, his hands touched the soft soil of the seabed, and the surrounding area of dozens of meters lit up with a faint blue light to form a huge refining array.

Located in front of Yun Hong, the center of the refining array, a turquoise ice ball caused a vortex on the bottom of the sea, and the seawater water was continuously sucked into this ice ball, hundreds of tons, thousands of tons, tens of thousands of tons!

The refining array on the bottom of the sea shrank with the mass of the seawater absorbed by the ice ball, and when both reached a critical value, Yun Hong closed his hand and held the ice ball, closing his eyes to feel the internal structure of the ball.

"The structure is still very unstable, and because the mass is spread out into the surrounding seawater to be suspended, once it is out of the seawater, no amount of air can withstand the mass of this puck, it will not work." Yun Hong shook his head in disappointment, and his right hand directly crushed the marble-like ice ball, and the ice ball burst out with a terrifying thrust in an instant, pushing his body thousands of meters away.

The eruption of water freed up to the surface of the sea for several kilometers and freezing, freezing a large amount of gravel soil and fish creatures, which were then pushed to the surface by the buoyancy of the sea.

"Boom!"

The pedestrians on the beach were stunned as they watched as an iceberg several kilometers in size suddenly emerged from the seabed in the distance, and the sea water splashed dozens of meters into the air to form a beautiful rainbow, and the strange spectacle attracted most of the people in the city to watch it at once.

Alchemy of ice

This is the limit that Yun Hong can do without the help of the Philosopher's Stone, although it is the alchemy of ice, in fact, the ice alchemist in "The Alchemist of Steel" can still make water boil, so it is more appropriate to call it the alchemist of water. In Yun Hong's opinion, this alchemy is one of the strongest alchemy in the animation, as long as there is water, the actual combat power of the ice alchemist can be called the strongest.

Back on the shore, the killer Shen Hua and the maid Robert were standing on the shore waiting for him, Shen Hua naturally noticed the ice floe that was several kilometers long, and she couldn't figure out what means Bai Yunhong used to achieve such an effect.

"Boss, you made that ice?"

Robert came over and put his mobile phone in front of Yun Hong and said respectfully: "Master, Captain Balalaika has called you and left a message, if you hear the message, please call her back immediately." ”

Yun Hong put his hands together and launched alchemy, the sea water of his clothes and body quickly retreated, and he took the mobile phone and called it back to Balalaika.

"Is it Mr. Yun?"

"Yes."

"It's ready to go."

"Then we will leave tomorrow afternoon, where."

"Roanapura East Coast."

"Okay." Yun Hong nodded in agreement, squinted his eyes at the lively appearance of the coast and said lightly: "Before I leave, I have a question, Captain Balalaika, what are you going to do with the Kabane virus?" ”

"Oh? Mr. Yun, since you are a passer-by in this world, why do you care about this? ”

"My conscience or something."

"You're the one who handed over the weapon to us, don't you already have the answer in your heart?"

"Hehe, just wanted to confirm."

"Mr. Yun, can you understand the feeling of being betrayed by your motherland and people?" Balalaika's voice was cold and frantic.

Yun Hong shook his head: "No, does Captain Balalaika want to talk about the unfair treatment he suffered as a soldier?" Since you are opposed by the motherland and the people, it means that you have only been given the wrong order to start the wrong war at the wrong time. ”

Balalaika laughed happily on the other side of the phone: "Hahaha, standing in the position of a bystander, of course, you can say this, we have lost everything, Mr. Yun also said that we are just a world of works, this world has gone crazy, I have witnessed the corruption and division of my country, the collapse of the faith of the people and soldiers, in this case, why not follow my own beliefs, and launch a revolution against the country that betrayed me, and the whole world!" Breaking all the rules and forming a new state and a new order, the Moskva Hotel has been cowering in this small Southeast Asian country for far too long. ”

After being silent for a while, Yun Hong chuckled and said, "I understand, I wish you good luck and prosperity." ”

Throwing the phone into the sea, Yun Hong said to himself with a smile on his face and a little disappointed: "It's a pity that you can't stay here for too long, otherwise you can watch a good show." ”

After a pause, he turned his head to Shen Hua and smiled: "This is the end of the cooperative relationship between us, I will put the goods in the hotel, once what I said happens, there must be a global outbreak of the virus before the box can be handed over to the corresponding person, you decide how to perform this task yourself, I just provide an optional way." ”

Shenhua Lenovo Yunhong once said some inexplicable things to her, and nodded hesitantly: "Yes, but I can't guarantee the success of the mission." ”

The global outbreak of the zombie virus, will this kind of thing really happen? Having seen Yun Hong's weird ability, she had to believe the words that came out of his mouth, no matter how ridiculous they were.

Yun Hong replied indifferently: "Just do your best, I also commissioned the task on a whim." ”

"Boss, are you leaving Roanapura?"

"Ah, goodbye."

"Well, there's something I want to tell my boss."

"What?"

Shen Hua corrected seriously: "My name is not Shen Hua, in Chinese it is Immortal Crane." ”

Yun Hong, who already knew this, smiled dumbly: "Well, I'll remember." ”

Shen Hua looked at the backs of Yun Hong and Robert in the distance, the cheongsam was lifted by the sea breeze, she pulled up her hair to reveal her delicate side face, the sound of the waves behind her and the sound of seagulls evoked her psychological melancholy, she was obviously used to being called Shen Hua, but in the end she inexplicably wanted to correct Yun Hong's name for herself.
