Over the vast grassland, shiny silver-white clouds float freely and leisurely, covering the summer sun like an umbrella, creating a grassland wonder of clouds moving and shading, and the lake reflects the sun, shining like jewels. The long wind is coming, blowing people's clothes.

Like a light breeze, Zhao Qing quietly flew for several miles, and came to a small island in the center of a nearby lake, and at the same time, his palm was spread out, and the pure and slightly glowing true qi was slowly injected into the crystal on his hand, making it exude a colorful and brilliant light.

If you look closely at this crystal clear, you will find that the crystal ball with a diameter of an inch is delicately carved into a three-layer hollow set of balls, each layer of which is nested on top of each other and can rotate freely, realizing the function of opening and closing.

Looking further down, the outermost layer of crystal seems to be covered with filamentous microscopic pipes, densely packed; The crystals of the middle layer are obviously inverted to form twelve holes with a diameter of about two points, which together form a regular icosahedral vertex structure;

The innermost layer of crystal, in the very center of the position seems to be filled with some substance, the refracted light has not changed very obviously, from time to time a little light brown, people inexplicably feel that these substances are in a state of extreme pressure.

Judging from the deuterium gas refinement that Zhao Qing just mentioned, it does not seem to carry other capacities, and the substance filled in the center of the crystal is a highly compressed, almost metallic state of solid deuterium.

And this crystal can actually withstand the high pressure of the atmosphere in such a state, which is obviously not an extraordinary product, in fact, the crystal spirit stone she found in the underground lake near Daxing City that day, the strength is more than ten times higher than that of ordinary crystal.

"The outer layer of X-ray mirrors is structurally normal and should be flawless; Under cryogenic cooling, the pressure on the solid deuterium is stable...... Next, it is necessary to set up the test site and observe and record the effect of its detonation. ”

Zhao Qing casually took out two slender dark iron probes, one needle tip was slightly shiny, and the other needle tip was dark and deep, and conducted a series of tests around the crystal ball, confirming that this miniature hydrogen bomb did not have any damage after being loaded with deuterium fuel.

"If the fusion reaction is sufficient and the verification of the small yield is completed, it proves that this hydrogen bomb with the imitation T-U configuration has no problems in design, and it can be increased by increasing the charge, and gradually develop into a hole card for me."

Retracting the two Xuantie probes, Zhao Qing walked around the island, took out two lead plates, fifty or sixty metal particles with different melting points of different materials, and arranged a lead plate and metal particles on the edge of the island, thinking secretly in his heart.

In her view, the meaning of the hydrogen bomb, a nuclear fusion weapon, is completely different from the nuclear fission of the atomic bomb.

In this world, although there have long been people mining and smelting tungsten ore and titanium ore on a small scale, for the rarer uranium ore, it has not been discovered and mined at all, and I don't know where the ore source exists.

Even if a large amount of uranium ore is successfully mined, the vast majority of natural uranium is uranium-238, which is difficult to fission, and the uranium-235 that can be fissioned accounts for only about 0.72%, and the latter must be purified to more than 97%.

For Zhao Qing, it is not impossible to purify uranium, and the slight difference in density between the two can be used to use the method of step-by-step separation and enrichment, that is, the uranium-containing gas is repeatedly rotated and centrifuged, but under normal circumstances, a round of purification can only increase the purity a little bit;

Therefore, if you want to extract the critical mass of 52 kg under the uranium-235 sphere, or the critical mass of 15 kg after adding the neutron reflector layer, but you don't know how much time it will take, referring to the progress of Yi~Lang enrichment in the previous life, it is estimated that it can be counted annually.

Considering the size of the finished atomic bomb and the time it takes to detonate it, the shock wave that does not significantly exceed the speed of sound accounts for a large proportion of its released energy, it can be said that it has little actual combat value, and at most acts as a landmine.

On the other hand, the hydrogen bomb can be extracted from water as its raw material, one ton of water has about 30 grams of deuterium, which is equivalent to the equivalent of more than 4,000 tons of TNT, and the refining speed is extremely fast.

It should be noted that the most deuterium in hydrogen cannot replace deuterium as a raw material for nuclear fusion weapons, because the process of fusion of two deuterium atoms to form a deuterium atom is normally an energy-absorbing reaction that must occur at the core of the star due to quantum tunneling;

Therefore, the vast majority of hydrogen in water cannot be used for nuclear fusion, and the two isotopes of hydrogen, deuterium and tritium, must be used to carry out it, and cannot achieve higher utilization rate in raw material refining.

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

Since there is a critical mass limit unlike uranium, once the problem of detonation is solved, in the small direction, the power can be sacrificed and the hydrogen bomb can be made into 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 yield of 100 million tons, and even has the possibility of reaching 10 billion tons or trillions of tons.

Considering that the trillion-ton yield can theoretically only blow up a large crater of hundreds of miles, it seems that it is not as destructive as the original Ouyezi in the illusion, but even if it reaches the "Upper Six Qi" realm, in the hands of similar strength, throwing out a few trillion-ton hydrogen bombs is estimated to be able to hit the opponent by mistake.

Of course, as an indiscriminate range attack weapon, the hydrogen bomb is not widely used, and many factors need to be taken into account. If the "Six Qi" realm has some kind of unknown resistance, 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 yield of the hydrogen bomb is said to have no upper limit, looking at the previous life, no design of more than 100 million tons was developed, and the highest was only the three-stage formula of Big Ivan, and there was no more powerful four-layer nesting, which shows that there are also problems to overcome.

In fact, as far as the current situation is concerned, because the "Danxiao" can only last for a maximum of several hundred breaths, the miniature hydrogen bomb designed by Zhao Qing himself must leave a channel so that it can be detonated close to the deuterium balloon in the very center, and it can only be a one-stage design, and the yield has its limit.

For example, the miniature hydrogen bomb she is holding in her hand at the moment that has not yet encapsulated "Danxiao" and entered the pre-launch stage is only loaded with about 10 grams of solid deuterium gas, and if it is fully nuclear fusion, it will only be more than 1,000 tons of TNT equivalent.

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

However, at close range, the high temperature of hundreds of millions of degrees, the huge amount of optical radiation and the neutron jet far exceed the former in terms of energy level, and it is an instantaneous explosion, which is extremely fast, making it difficult to resist.

……

As we all know, hydrogen bombs must be detonated by atomic bombs, but few people know that in essence, atomic bombs are nuclear fusion materials that are detonated by X-ray irradiation, not by fission.

Because if the nuclear material is fused by high temperature and high pressure, then when the nuclear fission high-temperature plasma reaches the nuclear fusion material, the nuclear fusion material has already been "blown away", and at best it can only react a few percent.

Any hot object will radiate energy outward, and to maintain a certain high temperature, sufficient energy must be generated inside the object or transferred to the object from the outside of the object, otherwise, the object will gradually cool.

In the case of high-temperature plasma, this radiation is mainly produced by the collision of electrons with ions and is known as bremsstramma, or X-rays.

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

Referring to this principle, Zhao Qing used extremely fine micro-carving techniques to carve a tube bundle composed 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 layer of solid deuterium.

As for the source of these X-rays, it is natural that the "Danxiao" is encapsulated and injected into the twelve holes specially set aside in the middle layer through the rotatable and closed opening of the outer layer of the crystal ball, and then detonated by excitation at the same time, while compressing and squeezing the deuterium in the center into a small group, it also releases a huge amount of X-rays.

And because the miniature hydrogen bomb itself is extremely small, with a diameter equivalent to the distance traveled by light in 10 billionths of a second, the explosion of Danxiao is slightly faster or slower, and there will be a huge difference in the light pressure of X-rays, resulting in the consequences of fuel dispersion and detonation dispersion.

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

In order to control the time to ensure simultaneous excitation, and to ensure that the time difference between the twelve miniature Danxiao explosions is within 10 billionths of a second, she specially developed a technique of aura pulse excitation, carving a probe that pierces the center of the crystal ball, and uses it to stimulate the aura in the ball to transmit the detonation signal.

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

It looks inconspicuous, but in fact, such a small crystal ball integrates countless esoteric techniques, which can be called the perfect use of Yuan Qi science, materials science and nuclear physics, and the degree of complexity and subtlety is better than any peerless magic skill in the world.

……

After arranging the materials to detect the effect of the nuclear explosion, Zhao Qing returned to the center of the island in the middle of the lake and took out a thin needle of cold iron with a faint blue color, the tip of the needle trembled slightly, drawing complex changes in a very small range, condensing a purple light cluster the size of a soybean.

After casting a "Danxiao" with a diameter of one inch with the tip of the sword half a month ago, after initially overcoming the method of Danxiao compression, she changed the long sword to an extremely thin long needle after many experiments, which significantly improved the accuracy of controlling the sword moves.

As the filamentous True Water True Fire reached a finer level, Danxiao was further compressed to the original volume of one hundred thousandth, but the power of a single one inevitably dropped to one or two percent of the original.

Therefore, in Zhao Qing's calculations, the power of such twelve ultra-miniature Danxiao, which was in the right position to excite and explode at the same time, could only roughly 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 tip of the needle shook slightly, pushing the purple light cluster into the hole in the crystal ball in front of her, and with the rotation of the sleeve, it was embedded in the space of the middle layer, and then, a new Danxiao condensed out.

Just like a revolver, twelve ammunition were loaded in turn, and the entire crystal ball was shrouded in a blue-purple glow, but the inner wall was not burned and melted, revealing Zhao Qing's superb aura manipulation skills.

After enhancing the restrained effect of Danxiao's Taiyin aura, the twelve purple light clusters no longer actively drifted and cut, and were specially designed to weaken their ability to resist interference, and were easily excited and detonated by the modulated crystal energy field.

There were still three hundred breaths left before the maximum lifespan of these Danxiao, Zhao Qing finally checked the situation inside the crystal, then drained the air inside, rotated and closed the passage between the layers, and slowly sent the crystal ball up to a low altitude of twenty zhang like a flying sword.

Holding the heavy lead plate, she retreated to the edge of the island more than thirty zhang away, the sound of the countdown silently flashed in her heart, and the moment after the end of the "one", she immediately stimulated a strong aura fluctuation around her, and it was transmitted towards the projectile body that was only a small dot forty zhang away diagonally.

In the next moment, there were still two hundred and ninety-nine breaths left before their maximum lifespan, and the twelve ultra-miniature Danxiao had exhausted their short lives ahead of schedule, dissipating in a rapidly expanding plasma flame;

Twelve clusters of blazing white light suddenly lit up in the small crystal ball, seemingly indistinguishable from each other, and the supersonic shock wave had just formed and tore through the thin crystal wall blocking the front, and a huge amount of light radiation, including X-rays, had 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 return to the deuterium fuel focused in the center of the inner layer of the crystal, so that they overcome the Coulomb repulsion between the nuclei at the moment of violent contraction and heating.

At intervals of less than a microsecond, the high-temperature and high-pressure plasma released by Danxiao further compressed the deuterium nucleus in the center to an unimaginable degree of condensation after X-rays, and only then was a small part of the nuclear fusion that had just been ignited, and quickly diffused to all the deuterium atoms.

In an instant, with a huge neutron jet, the chain reaction became faster and more violent, and endless energy gushed out like a tide, liberated from the tiny deuterium nucleus.

At first, it was just a tiny point of light, but within a few microseconds, it spread into a huge high-temperature and high-pressure fireball, which was hundreds of times brighter than the sun, and it took a few milliseconds for the ball of light to reach a maximum radius of 20 zhang, touching the ground of the island, and turning the entire island in the middle of the lake into a sea of fire.

Then the photosphere dimmed and ruptured, releasing a strong supersonic shock wave, in which the formation of high temperature heated the surrounding gas, causing the gas to rise rapidly to form a mushroom-shaped cloud, and at the same time, the low pressure generated at the explosion sucked the air and dust below, forming a columnar smoke.

Eventually, the columnar soot and the top cloud will combine into a huge mushroom cloud that will be enough to see clearly from hundreds of miles away.

The shock wave slowly decays into sound waves as the distance increases, and then gradually degenerates into infrasound waves through atmospheric absorption, reflection, refraction, scattering, dispersion, etc., which is enough to propagate in the air for more than 10,000 miles before the attenuation disappears.

Theoretically speaking, a nuclear bomb with a 1,000-ton yield can be designed to kill ordinary people at an instantaneous distance of more than 200 zhang, but for Zhao Qing, as long as she is not in the nuclear fireball, with the multiple defensive barriers she deploys, she will not be traumatized.

Carrying out high-precision observation of the detonation effect of the hydrogen bomb at this point only from the edge of the nuclear fireball is certainly much better than staying outside the room, and more reliable data can be collected.

As for taking a lead plate in front of her, she was worried that gamma rays and high-energy neutron jets might have the effect of damaging the primordial spirit, just in case; A simple radiation injury, with its strong recovery ability and rebirth effect, will never have a long-term effect.

However, although it had been carefully calculated in advance and sufficient protection was placed, when the nuclear explosion really happened, Zhao Qing suddenly discovered a new change that was beyond her expectations.

About the power of nuclear bombs: the meteorites that exterminated the dinosaurs were as high as 100 trillion tons of TNT equivalent, leaving a crater of 180 kilometers in diameter

There's something to update later.,More 6k tomorrow.
