In the blink of an eye, it came to the early morning of the next day, Zhao Qing collected the three or four "impurities" that had been smelted out of the furnace, opened an isolation room directly below the furnace that was pumped into a vacuum, and took it out little by little without affecting the sword tire that had reached a hundred refining above, and loaded it into the feed ports of other machinery on the side in batches, and carried out a series of treatments such as cooling, shaping and preservation.

Although it is only separated and the refining speed cannot keep up with the "impurities" of the main body, it is still a large section of the dark iron that is far beyond the ordinary in terms of quality, and it is quite considerable in terms of quantity, and it should never be wasted at will.

In the process of refining from ten to one hundred refining, Zhao Qing observed that the dark iron in the furnace seemed to be transforming into another new material, and heavy ripples emitting electric light would spontaneously appear on its surface, as if a layer of cyan thunder scales was attached, which she named "thunder scale iron".

Generally speaking, this kind of spiritual material with special patterns basically has some outstanding characteristics, which means that it does not need to be refined and sublimated into a higher-level material, and it has reached the standard of casting divine weapons.

According to her many tests, the "Thunder Scale Iron" turned into after a hundred refining of Xuantie has a strong memory deformation effect, and it is a rare ferromagnetic shape memory alloy, which can undergo memory deformation under the action of magnetic fields, and even has the ability to automatically repair small areas of damage.

Considering that in the refining process, the prototype of the sword fetus formed by it was shattered again and again, and the cycle repeatedly, perhaps the sublimation direction of this spiritual gold actually has the adaptability of the "environment"?

All in all, after transforming into "Thunder Scale Iron", it became a little more resistant to the power it exerted on Zhao Qing, and the time of each refining began to gradually become longer, and the rate of absorbing sword intent and heaven and earth aura continued to accelerate.

It is worth mentioning that the newly refined "thunder scale iron", with the continuous increase in the temperature in the furnace, is still gradually increasing in some unknown way, although it was divided into a small half this time, but the total amount is still as high as eight or nine thousand catties, but there is something she expected.

"It seems that the demand for sword intent in the sword embryo will continue to increase, and there needs to be no repetition in the type of artistic conception and the interpretation of changes, which can be regarded as a rare test, if I didn't manage to improve the durability of the spirit, I may not be able to survive many days."

Zhao Qing's mind moved slightly, and the invisible sword intent filled the heavens and the earth, all of which filled the subtle places in the furnace that were invisible to the naked eye, wrapping the emerald blue thunder scale iron in it, as if forming a big cocoon, feeling the rapid "threading" in the cocoon, and couldn't help but think secretly.

At her current realm, her body is basically powered by the Heaven and Earth Yuan Qi, and many of the original organs and tissues in her body have lost most of their functions, although they can be used to store energy, but they mainly exist only to maintain the stable circulation of True Qi and Gang Qi.

In order to make full use of the body's abilities and be more conducive to cultivation within the scope of physiology, Zhao Qing tried to optimize most of the cells and tissues in the body for several rounds, and induced a large number of pluripotent stem cells to differentiate, replacing the useless fat with neurons and glial cells.

As we all know, the source of human wisdom is closely related to the tens of billions of neurons in the brain, and the number of synaptic links of neurons can affect the efficiency of the brain and the speed of thinking about problems;

Obviously, spiritual-related practices must have a certain relationship with the nervous system, and even if the seven senses and eight senses are opened, and the yin and yang gods are cultivated, and the form and spirit are contracted to the void, most of them can also exert beneficial effects by strengthening the nervous system, just like the deep connection between the strength of the body and the essence and blood, muscles and bones, and muscles.

Therefore, considering the important role of wisdom and spiritual power in her cultivation, after she had the ability to be reborn, although she did not grasp the optimization of the neural structure of the brain, she only promoted the formation of synapses a lot, and was worried that there would be adverse effects that would be difficult to recover.

However, in other parts of the body, a large range of cell-level transformation has been carried out, and a large number of nerve cells have been cultured and integrated into the viscera through special guidance, which has completely replaced the fat in the body with nerve tissue, making the total number far more than ten times that of ordinary people.

Of course, most of these staggering densities of neural tissue are astrocytes that support and supply energy, and there are only two or three trillion new neurons, which can be transformed from the former to the latter when necessary.

However, according to Zhao Qing's observation and experience afterwards, although the total number of neurons has increased many times, due to the lack of special structure of the brain, or the reason for being separated from each other, the improvement of wisdom and mental power is not obvious, and it only improves the durability of her spiritual output.

If she wants to really make these new neurons gain wisdom, it is estimated that she will have to carefully study the subtle changes in the intelligence of the viscera at each stage of Shenjin, and even conduct in-depth research in brain science and neurobiology.

After nearly ten hours of high-precision and high-intensity control, it was necessary to additionally fuse magnetic field information, and constantly consume mental energy to instill sword intent, even if she relied on the method of distraction and the exhalation of a large amount of heaven and earth essence, Zhao Qing should have been slightly weakened, but because of this transformation of her body, she became more and more energetic.

Calculating the changes in the parameters of each refining of the Thunder Scale Iron, her mind flashed, and she constructed a rough model of the divine soldier, which was repeatedly shaped with the help of its magnetic memory properties, and it was speculated that it should be able to play a certain role when it was officially formed.

……

Day after day, and soon another eight days passed, during which on the seventh day, the sun erupted with a small flare that transmitted a lot of extra energy to the thunderclouds in the sky.

In the middle of the night on the ninth day, the crowd in the square was still the same, most of them were inquiring about the source of the vision of heaven and earth, and few of the spectators who wanted to witness it up close still paid attention to the various things on the field.

"This is He's Bi?! Legend has it that Emperor Qin carved the piece of Hebi that was 'ordered by the sky, both longevity and eternal prosperity'! I actually saw it here with my own eyes...... What? Did she want to throw this supreme treasure into the furnace? ”

Suddenly, a few sharp-eyed innate hands who could clearly see that Zhao Qing had taken out a piece of jade casually, and discovered the origin of this jade under the reflection of the starlight, and couldn't help but suspect that he was dazzled, and then shouted in shock.

With the increasingly magnificent thunderclouds and stars in the sky, Zhao Qing did not hesitate to take off the gold-inlaid corner of He's bi, and then put it into the open furnace, which immediately inspired a diffuse galaxy phantom, which quickly expanded and covered the entire square.

Immediately afterward, she took out the Evil Emperor Relic that had been drained of the evil qi and dead qi, and poured two separate true water and true fire into it, which was enough to trigger the Great Sanhe Cave to penetrate the Immortal Gate, and also threw it into the furnace, guiding the two treasures to melt quickly inside, gradually merging with the thunder scale iron that had reached the level of a thousand refinements.

In an instant, I saw a violent noise erupt in the furnace, and the Heshi Bi and the Evil Emperor Relic leaked out the majestic energy they contained in the process of melting, forming a distorted spatial channel in the center of the air mass of the thunder scale iron, integrating the extremely pure void energy in the bi into it;

In the next moment, the void inside the space passage rapidly expanded and became larger, and continuously inhaled the surrounding Sun True Fire and Taiyin True Water, and in this inner space, Yin and Yang radical changes occurred, exploding the space more and more widely, and the Yin and Yang were clear and differentiated, and gradually evolved into a new world.

According to the "Heavenly Soldier Refining Form Induction Qi Method", a person can be managed to refine into a supreme divine weapon, then the divine soldier must also have the possibility of being refined into a "human", which means that it can imitate the mystery of the human body to refine, so that Zhao Qing, who has a limited understanding of refining weapons, deduced the general steps of refining soldiers.

With the Yin and Yang lines as the meridians, the spirituality of the birth was refined with the sword intent, and then the high-level vitality contained in the Heshi Bi and the special space of the Evil Emperor Relic, Zhao Qing added a side equivalent to the human dantian qi sea to the prototype of the divine soldier in the furnace, which can naturally circulate and provide energy to the Yuan Qi world, and with the help of the power of Yin and Yang Wuji, its essence was officially pushed to the level of the divine soldier, and it had the qualification to derive the law of vitality.

Keeping the opening of the inner heaven and earth always located inside the thunder scale iron air mass, suppressing the vitality energy gushing out of it without leaking out, in the seemingly endless flame of light, the air mass faintly appeared a fleeting dragon thunder pattern, which seemed to have been greatly sublimated in quality and spirituality.

After thousands of refining and separating a large number of "impurities", the thunder scale iron with less than a thousand catties left completely stabilized from the fierce fluctuations and condensed into a sword fetus again, the whole body showed a crystal clear jade state, as if the ice blue in the haze was filled with fairy energy.

This newly born high-quality spiritual material, Zhao Qing tentatively named it "Qingyu Dragon Pattern Iron", in the follow-up test, it was found that it can store a variety of memory forms, and can slightly change the volume density, thermal conductivity, magnetic conductivity, and electrical conductivity in the form change, and can be activated and manipulated by the sword intent of the sword master.

And after the newly condensed green jade dragon pattern sword tire went through another eighty refinements and shrunk to three feet, when it should have reached the most stable and condensed state, the sword tire itself seemed to have given birth to real life, constantly trembling and beating, making a humming sound like a tiger roaring dragon;

With the unimaginable burst of the vast electromagnetic field, enveloped in endless sharp qi, the countless sword intents that had been integrated into it in the previous nine days circled around at an extremely high speed, and suddenly spread, thus triggering the violent wind of essence to rage and sweep in all directions.

At the same time, the heavy dark clouds that had been accumulated for nine days began to pour down like endless water, and the storm thundered and lightning everywhere, as if something earth-shattering was about to be born in the midst of this natural disaster-like fluctuations.

After absorbing a large amount of magnetic field information, Zhao Qing's sword intent naturally had a sense of depth and depth, integrating and carrying the history of the Loess Plateau for 30 million years, even if it was just an inadvertent leakage, it was enough to make people feel a deep sense of coercion and deterrence.

At this moment, in the face of this fully released sword intent impact, the people in the entire Daxing City woke up from their sleep by the biting cold in an instant, and their hearts were in a trance, and there was a tendency to fall into it and lose themselves in the endless information.

And in a radius of thousands of miles, every master who had cultivated the sympathy of heaven and man stared at the sky, and in an instant, he felt that the heaven and earth disappeared, and in his place was a grand sword intent world that was difficult to describe in words, oppressing and sharpening the various divine intents they had cultivated by hard work.

In the sense of these people, there seems to be a majestic sword mountain in the distant sky, towering at the end of the earth, bordering the sky, and can be seen clearly at any time and place, but no matter how you advance, you can't get close to the foot of this giant peak.

……

Judging that the overwhelming impact of the sword intent of the Qingyu Sword Fetus continued, which was enough to turn the creatures within a radius of more than ten miles into idiots who had disappeared in a short period of time, Zhao Qing knew that the refining of the Divine Weapon had reached a new stage, so he decisively leaped up and decided to change to a safe position to finish the steps.

I saw that she leaned out a ten-zhang long Yuan Qi hand, quickly took out the sword embryo from the furnace, and then rushed straight to the sky with the sword, wrapped in a vast river of sword qi, and the scorching light of Xuan He in the sky, along the falling Xuantie cable, it was regarded as a cloud ladder to the sky, climbing to a height of two hundred miles.

Focusing on the blazing sword fetus that was dragged behind her like a meteor and leaving behind a brilliant tail flame, sensing that all the light and heat between heaven and earth seemed to be torn apart by the sword light, Zhao Qing went straight through the half-shrunken rose-shaped thundercloud, straight into the nine clouds, and finally stayed in the center of the ionospheric maelstrom.

With the help of the undulating electromagnetic force field here, as well as the ring cable locked by the quantum, she can completely float freely in this area without fear of falling, and directly use the sword tire with soaring magnetic energy to attract a huge amount of current to further refine it, and collect the energy of the Yuan Qi world inside the sword tire.

In the later stage of the refining of the divine weapon, Zhao Qing, who had no relevant experience, was finally able to fully calculate the various abilities and characteristics that the finished product would have, so as to make the final adjustment and shaping, and constantly send out a small Danxiao "hammer" to hit the sword tire, forging a divine sword that could give full play to its own advantages.

"It's almost done!"

Hour by hour, until the morning sun was approaching, and at a distance of ten zhang, she sensed that the mystical changes contained in the embryo of the divine soldier gradually evolved to the end, and she was about to usher in consummation, her heart moved, and her face was rarely filled with expectation.

In the next moment, with an unprecedented siphon of energy, centered on the sword tire that naturally suspended in the air and had a golden light, the plasma vortex storm that stretched for thousands of miles came to an abrupt end;

The vortex ring-shaped arc streamers completely dimmed, and the whole began to quickly decompose and collapse from the center, which was really an unimaginable spectacle, but unfortunately only Zhao Qing could witness it from a close distance.

Surrounded by hundreds of millions of brilliant starlight that revolved along the trajectory of Xuan's mystery, Zhao Qing watched as the surface of the three-foot sword embryo in the distance suddenly fluttered and scattered a large area of gray-black impurity dust, revealing countless inexplicable lines on the sword surface, and the whole body emitted an azure ice-blue divine light, with a sense of penetrating the void.

Immediately afterwards, a circle of dazzling light suddenly lit up on the side of the sword tire, like the infinite strings of Tai Chi, dividing yin and yang, cutting through the presence and nothing, and letting it slowly separate into two pairs of swords that can be combined with each other, the blade is as thin as paper, crystal clear and transparent to the point of incredible.

Because all the heat in the sky was absorbed into the sword body, the two extremely light divine swords did not have the heat of high-temperature smelting at all, but looked a little cold and cool, and under Zhao Qing's hand, they fell into her hands.

Although the blade of the sword is amazingly thin, the weight of the double sword should not be underestimated, each sword is three hundred and sixty-five catties, which shows that the density of this green jade dragon pattern iron material is outrageous, and it is more than ten times better than Xuantie.

From the perspective of the divine soldiers, these two swords only have a nascent spirituality, share the same Yuan Qi world, and have a complete Yuan Qi law when they are added together, which is essentially only one or a set of divine weapons, not two.

"The east belongs to the earthquake, it is the party of the rising sun, so the clouds are aurora. Lou Tan Jingyun: 'East of the river, named Aurora. At the beginning of the day, it shines in the east corner, so it is named. ’”

Glancing at the early sun slowly rising in the far east of the extreme, Zhao Qing's heart moved slightly, and he decided on the name of this pair of divine swords: "The Yang Sword is 'Aurora', and the Yin Sword is 'Cambrian', which is named after the geological era, indicating the deep connection between the refining of this sword and the geomagnetic history." ”

"Among them, 'Aurora' has the meaning of China, and 'Cambrian' is a great explosion of life, and the two swords are combined into one, symbolizing the beautiful prospect that China will begin to flourish from now on."
