The Heavens: A Qing, the Yue Girl at the beginning

Chapter 336 The Mushroom Cloud Over the Grassland (4K)

Over the vast grassland, shiny silver-white clouds float leisurely and freely, blocking the afternoon summer sun like an umbrella, creating a spectacle of the grassland where the clouds move and shade, and the lake water reflects the sunlight, shining like gems.The long wind blows slowly, blowing people's skirts.

Like a gust of wind, Zhao Qing flew silently for several miles, and came to a small island in the center of a nearby lake. At the same time, she spread her palms open, and pure and slightly shining zhenqi slowly poured into the crystal in her hand. Make it emit a colorful and brilliant light.

If you observe this crystal clear spherical crystal carefully, you will find that the crystal ball with an inch diameter has been carved into three layers of hollow balls with extreme precision, and each layer is stacked on top of each other and can rotate freely to achieve function of opening and closing.

Taking a closer look, the outermost layer of crystals seems to be densely packed with filamentary micro-channels; the middle layer of crystals is obviously indented to form twelve holes with a diameter of about two centimeters, which together form a positive dichotomy. The vertex structure of the decahedron;
The innermost layer of crystal seems to be filled with some substance at the very center, and the refracted light shows inconspicuous changes, showing a bit of light brown from time to time, which makes people feel inexplicably that these substances are in a state of extremely high pressure Down.

Judging from the deuterium gas extraction that Zhao Qing just mentioned, but it does not seem to carry any other capacity, the substance filled in the center of the crystal is exactly the highly compressed, solid deuterium that is almost in a metal state.

And this crystal can withstand the high pressure of the atmosphere in such a state, obviously it is not extraordinary. In fact, it is the crystal spirit stone she found in the underground lake near Daxing City that day, and its strength is more than ten times stronger than ordinary crystals.

"The structure of the X-ray reflector on the outer layer is normal, and there should be no flaws; under low temperature cooling, the pressure on the solid deuterium is stable...The next step is to set up the test site and observe and record its detonation effect."

Zhao Qing casually took out two slender dark iron probes, one with a slightly shiny tip and the other with a dark and deep tip, and conducted a series of tests around the crystal ball, confirming that the miniature hydrogen bomb was loaded with deuterium fuel. There is no damage.

"If the fusion reaction is sufficient and the verification of the small equivalent is completed, it proves that the design of this TU-like hydrogen bomb is not a big problem, and the power can be increased by increasing the charge, which will gradually become my trump card."

Taking back the two black iron probes, Zhao Qing wandered around the small island, took out two lead plates, fifty or sixty metal grains with different melting points, and arranged a lead plate and metal grains on the island. Edge, thinking secretly in his heart.

In her opinion, the significance of nuclear fusion weapons such as hydrogen bombs is completely different from the nuclear fission of atomic bombs.

In this world, although people have already mined and smelted tungsten ore and titanium ore on a small scale, the rarer uranium ore has not been discovered and mined at all, and it is not known where there is a source of ore.

Even if a large amount of uranium is successfully mined, most of the natural uranium is uranium-238 which is difficult to fission, and the fissionable uranium-235 only accounts for about 0.72%, which must be purified to more than 97%.

For Zhao Qing, it is not impossible to purify uranium. The slight difference in density between the two can be used to use the method of step-by-step separation and enrichment, that is, to repeatedly rotate and centrifuge the uranium-containing gas. However, under normal circumstances, one round of purification can only add a little bit of purity;
Therefore, if you want to extract the critical mass of 235 kg under the uranium 52 sphere, or the critical mass of 15 kg after adding the neutron reflector, you don’t know how much time it will take. count.

Considering the large size of the finished atomic bomb and the time it takes to detonate it, and the shock wave that cannot obviously exceed the speed of sound accounts for a large proportion of its released energy, it can be said that it has almost no practical value, and at most acts as a mine.

On the other hand, hydrogen bombs, whose raw materials can be extracted from water, have about 30 grams of deuterium in one ton of water, which is equivalent to more than 4000 tons of tnt, and the extraction speed is extremely fast. First, hydrogen is collected by electrolysis, and then lowered to ultra-low temperature and pressured to make protium Deuterium separation, if skilled, only takes a moment.

It should be noted that protium, which is the most abundant element in hydrogen, cannot replace deuterium as a raw material for nuclear fusion weapons, because the process of fusing two protium atoms to form a deuterium atom is normally an energy-absorbing reaction that must be carried out in the core of a star. Occurs due to quantum tunneling;
Therefore, the vast majority of hydrogen in water cannot be used for nuclear fusion. Two isotopes of hydrogen, deuterium and tritium, must be used for nuclear fusion, which cannot achieve a higher utilization rate in raw material extraction.

Considering that the content of tritium is far rarer than that of deuterium, it is quite troublesome to find and refine lithium 6, which can be used to prepare lithium deuteride. The fusion fuel she filled into the hydrogen bomb is pure deuterium, and the reaction conditions are higher. , but under the same mass, it can release more than half of the energy than the deuterium-tritium reaction.

Unlike uranium, which has a critical mass limit, once the problem of detonation is solved, the power can be sacrificed to make the hydrogen bomb the size of a grain of rice, which can be used as a hidden weapon;

Looking at the general direction, the upper limit of the power of the hydrogen bomb can at least reach the equivalent of [-] million tons, and it may even reach [-] billion tons or trillion tons. It is absolutely not a problem to kill the "lower six qi" environment, and the "middle six qi" The environment should also be able to hit hard if it hits.

Considering that the trillion-ton equivalent can theoretically only blow up a large hole of hundreds of miles, it seems that it is not as destructive as Ou Yezi's destructive power in the original illusion, but even in the "Upper Six Qi" realm, in a match of similar strength, throwing A few trillion-ton hydrogen bombs are estimated to be able to hit the opponent with a wrong hand.

Of course, as an indiscriminate range attack weapon, the use scenarios of hydrogen bombs are actually not extensive, and many factors need to be considered.If there is some kind of unknown resistance in the "six qi" realm, or maybe the rules of heaven and earth in the main world are different, maybe the effect will be reduced a lot.

What's more, although the equivalent of the hydrogen bomb is said to have no upper limit, but in the previous life, no design of more than [-] million tons has been developed. The highest is only the three-stage type of Big Ivan, without the more powerful four-layer nesting, so it can be seen that there are also problems need to overcome.

In fact, as far as the current situation is concerned, the miniature hydrogen bomb designed by Zhao Qing himself can only last a few hundred breaths at the longest, so a passage must be left so that it can be detonated close to the most central deuterium balloon. It can only be a one-stage design, and the equivalent has its limit.

For example, the unencapsulated "Danxiao" miniature hydrogen bomb that she is holding in her hand at the moment has entered the pre-starting stage. It is only filled with about 10 grams of solid deuterium gas. If it is fully nuclear fusion, it will have an equivalent of more than a thousand tons of TNT That's all.

In terms of large-scale destructive power, it is actually not much stronger than the high-intensity thunderstorms and large-scale tornadoes she can produce in a certain period of time;

However, within a short distance, the high temperature of hundreds of millions of degrees, the huge amount of light radiation, and the neutron jet are far superior to the former in terms of energy level, and the explosion is instantaneous, and the speed is so fast that it is difficult to resist.

……

As we all know, a hydrogen bomb must be detonated by an atomic bomb, but few people know that, in essence, an atomic bomb is a nuclear fusion material detonated by X-ray irradiation, rather than using fission high temperature and high pressure to cause nuclear fusion.

Because if high temperature and high pressure are used to fuse nuclear materials, when the nuclear fission high-temperature plasma reaches the nuclear fusion materials, the nuclear fusion materials have been "blown" away, and the reaction can only be a few percent at best.

Any high-temperature object will radiate energy outward. To maintain a certain high temperature, sufficient energy must be generated inside the object or transmitted from the outside of the object, otherwise, the object will gradually cool down.

In the case of high-temperature plasmas, this radiation is mainly produced by collisions between electrons and ions, and is called bremsstrahlung, or X-rays.

After discovering that the hydrogen bomb should be detonated by X-rays, Taylor and Ulesu of the United States used the X-ray reflective layer to focus the X-rays produced by the atomic bomb explosion on the fusion material, and successfully developed the hydrogen bomb, which is generally called It is the TU configuration.

Referring to this principle, Zhao Qing used extremely fine micro-carving technology to carve a tube bundle consisting of hundreds of thousands of hollow capillaries in the outer layer of the crystal spirit stone to guide X-rays and focus them on the innermost solid state. Deuterium on.

As for the source of these X-rays, it is naturally that the "Dan Xiao" is injected into the twelve holes specially reserved in the middle layer through the rotatable and closed opening of the outer layer of the crystal ball, and then detonated by simultaneous excitation. While being compressed into a small ball, it also released a huge amount of X-rays.

And because the miniature hydrogen bomb itself is extremely small, its diameter is only equivalent to the distance that light travels in ten billionths of a second. Dan Xiao's explosion is slightly slower, and there will be a huge difference in the light pressure of X-rays, causing the fuel to scatter , The consequences of detonation and dispersion.

Compared with this extremely short time difference, since the atomic bomb is activated by explosives, the accuracy only needs to reach one millionth of a second, which is not at the same level of difficulty at all.

In order to control the timing and ensure simultaneous activation, and to ensure that the time difference between the twelve miniature Danxiao explosions is within a ten-billionth of a second, she specially developed a technique for aura pulse excitation, and carved a crystal ball pierced into it. The probe in the center is used to stimulate the aura in the ball to transmit the detonation signal.

If the projectile body is not made of uniform and high-purity spiritual materials, this spiritual energy pulse will inevitably be hindered and abnormal refraction will occur. Therefore, this kind of spiritual stone crystal can be regarded as one of the necessary raw materials for miniature hydrogen bombs before the technology is updated. one.

It looks inconspicuous, but in fact, such a small crystal ball integrates countless profound skills, which can be called the perfect application of vitality, material science and nuclear physics. Peerless magic.

……

After arranging the materials for detecting the effect of the nuclear explosion, Zhao Qing returned to the center of the island in the center of the lake, and took out a thin blue cold iron needle. A purple light cluster the size of a soybean.

After casting a "Dan Xiao" with a diameter of an inch with the tip of the sword half a month ago, after initially conquering the method of Dan Xiao's compression, she changed the long sword into an extremely thin long needle after many experiments. This significantly improves the accuracy of controlling sword moves.

As the silky real water and real fire reached a finer level, Dan Xiao was further compressed to one hundred thousandth of the original volume, but the power of a single pellet also inevitably dropped to one or two percent of the original.

Therefore, according to Zhao Qing's calculations, with the power of twelve ultra-miniature danxiaos in the right position, they can only detonate 12 grams of deuterium fuel, leaving a margin of 2 grams.

I saw that after the cold iron long needle in her hand completed a Danxiao, the needle tip vibrated slightly, pushing the purple light cluster into the hole in the crystal ball in front, and with the rotation of the sleeve, it was embedded In the middle space, a new Danxiao condensed out immediately after.

Just like a revolver, twelve ammunition were loaded in sequence, and the whole crystal ball was shrouded in a blue-purple light, but the inner wall was not burned and melted, revealing that Zhao Qing Superb aura manipulation skills.

After enhancing the introverted effect of Danxiao Taiyin's aura, the twelve purple light clusters no longer actively drift and cut, and are specially designed to weaken their anti-interference ability, so they are easy to be stimulated and detonated by the modulated crystal energy field.

There are still [-] breaths before the maximum lifespan of these Dan Xiaos. Zhao Qing finally checked the situation inside the crystal, then drained the air inside, and rotated to seal the passages between the layers. The crystal ball was slowly sent to a low altitude of twenty feet.

Holding a heavy lead plate, she retreated to the edge of the island more than 30 feet away. The sound of countdown flashed silently in her heart, and the moment after "One" ended, a strong spiritual energy wave was aroused around her, and she moved towards the diagonally upwards. Forty feet away, only a small projectile passed.

In the next moment, there are still 290 breaths before the maximum lifespan, and the twelve ultra-miniature Dan Xiaos have exhausted their short life ahead of time, dissipating in a rapidly expanding plasma flame;

Twelve clusters of blazing light suddenly lit up in the small crystal ball, seemingly indistinguishable from each other. The supersonic shock wave had just formed and tore the thin layer of crystal wall blocking the front. A huge amount of light radiation has already penetrated to the outer layer;
Then, these X-rays rush into the outer layer of hundreds of thousands of hollow capillary crystals, and after intensive reflection and refraction, a considerable part of them are returned and focused on the deuterium fuel in the center of the inner layer of the crystal, making it overcome the Coulomb repulsion between atomic nuclei;
In less than a microsecond interval, the high-temperature and high-pressure plasma released by Dan Xiao followed the X-rays and further compressed the deuterium nuclei in the center to an unimaginable degree of condensation. A small part of the nuclear fusion that had just been ignited spread rapidly. to all deuterium atoms.

In an instant, accompanied by a huge jet of neutrons, the chain reaction became faster and more violent, and endless energy gushed out like a tide, and was liberated from the tiny deuterium nucleus.

At first it was just a tiny spot of light, and within a few microseconds, it spread into a huge high-temperature and high-pressure fireball, whose brightness was hundreds of times that of the sun, and it took a few milliseconds for the ball of light to reach the maximum radius of twenty feet and touch the ground of the island. , turning the entire island in the center of the lake into a sea of ​​flames.

Then the photosphere dimmed and burst, releasing a strong supersonic shock wave. The high temperature formed in it heated the surrounding gas, causing the gas to rise rapidly to form a mushroom head cloud. At the same time, the low pressure generated at the explosion sucked up the air and dust below, forming a columnar soot.

Eventually, the columnar soot and overhead cloud will combine to form a giant mushroom cloud that can be seen hundreds of miles away.

The shock wave gradually attenuates into a sound wave as the distance increases, and then attenuates through atmospheric absorption, reflection, refraction, scattering, dispersion, etc., and gradually degenerates into an infrasonic wave, which is enough to travel more than ten thousand miles in the air before attenuation disappears.

Theoretically speaking, a nuclear bomb designed with a thousand-ton equivalent can instantly kill an ordinary person at a distance of more than 200 feet. However, for Zhao Qing, as long as she is not in a nuclear fireball, she will not be affected by any damage due to her multiple defensive barriers. trauma.

At this position only away from the edge of the nuclear fireball, conducting high-precision observations of the detonation effect of the hydrogen bomb is definitely much better than staying inside and outside, and more reliable data can be collected.

As for holding a lead plate in front of her, it was because she was worried that gamma rays and high-energy neutron jets might have the effect of damaging the soul, just in case; simple radiation injuries, relying on the strong recovery ability and reborn The effect will never be affected for half a minute.

However, despite precise calculations and adequate protection, when the nuclear explosion actually happened, Zhao Qing suddenly discovered a new change beyond her expectations.
