A few days later, in the northeast of the Yuema Bridge, a large-scale mansion with many houses occupied more than other mansions in the country, and the courtyard could accommodate more than thousands of people.

This was the mansion of Chen Gong, a close confidant of Yang Su in the past, and was later bought by Dugu Valve as their stronghold in Daxing City, named "Xijiyuan", there are four wells in the park, which are located in the southeast, northwest and northwest, and the north well is actually the secret entrance of Yang Gong's treasure house.

Now, because Dugu Valve realized that the Sui Dynasty was about to die, but he only had the comprehensive strength of the four valves, and it was too late to lay out in the army, he met Zhao Qing's visit, and after measuring it for a long time, he offered the mansion of Xijiyuan in a timely manner, hoping to have an extra way back.

Controlling one of the entrances to Yang Gong's treasure house, with Zhao Qing's skill and sensing ability, he can break into the underground treasure house at any time, forcibly remove the mechanism in the tunnel, and use the secret passage connecting the inside and outside of the city, the treasure house to the palace, and play a role at a critical moment.

At the same time, the largest prefecture in the West Market area can also secretly station a considerable number of people and horses as an important base in Daxing City, and under her instructions, some of them have been transformed into places for the study of technology and craftsmanship.

The Fuju Building, which was originally chosen by Zhao Qing to monitor the surroundings of the Prancing Horse Bridge, was mostly concerned by others due to her big fight a few days ago, and it was easy to find signs, so some people were sent upstairs to assist in observation.

……

That night, in the south of Xijiyuan, which was named "Daxing Research Institute No. 1" by Zhao Qing, in one of the large basements that had been recently excavated and arranged, an industrial experiment was being carried out that transcended the times.

This is an underground space of seven or eight zhang square, with a number of pipes connected to the water body of Yong'an Liang built at the edge, surrounded by complex gears, connecting rods and other force transmission structures, connected to a large machine in the room, and a blazing furnace not far away.

And at the entrance of the material processing that seems to be open to this large machine, on a platform nearby, there are many pieces of jet-black, glittering metal, and on the side is a jade-faced, red-lipped, delicate and youthful girl.

Her hair is black and shiny, and her pale complexion is set off by jade bones and ice muscles, which is extremely moving, and she wears a men's bun on her head, ties a white hero scarf, and stares at the machinery in front of her, as if she is stunned.

This woman is the little princess of the Ryukyu Dongming faction, Shan Wanjing, because Zhao Qing sent Zhang Zhenzhou to lead the sailors to visit the Dongming faction, and wanted to recruit this force that is good at crafting high-quality weapons, she arrived in Daxing a few days ago, temporarily lived here, and a group of craftsmen who followed the line participated in the research.

"The toughness of black steel and its melting point are far more than Chang Tiefan steel, and it is the main material of 'clear steel' in the materials for building divine weapons, although the value is not as good as Xuantie, cold iron, Xuanjin, etc., it is also precious, and it is also the second-class forging material in the world."

"This 'hydraulic forging machine' that you have made, if you want to use the power of weak water to replace the hard internal force of the foundry master to temper and forge it, can it really forge black steel, instead of destroying and wasting it?"

Not far from Shan Wanjing, an old man between forty and forty-five or sixteen widened his eyes, shook the cigarette stick in his hand, and asked in a deep voice.

This person is a well-known archer master "Arrow Master" in the northeastern border, who has made seven divine bows such as "Piercing the Sun" and "Shooting the Moon", many of which shine in the hands of the original Shuanglong.

His half-bald head was carried by a long neck that seemed to be overwhelmed, and he had two gray beards, his eyes were tired and thoughtful, his face was sagging, his eyes were swollen, and he looked like he had been addicted to wine for many years.

In terms of skill alone, he is second only to Lu Miaozi in the world, not only has a special expertise in making bows and arrows, but also has a deep attainment in casting and appreciating weapons, and is not under anyone in the Dongming faction.

The Arrow Master himself has high skills and has trained many apprentices, so he naturally got Zhao Qing's attention, and sent someone to recruit him, agreeing to help him take revenge on the evil thief Shen Mohuan of Murowei in the future, so that the Arrow Master came here to study.

"Zhao Qing's predecessors were able to strengthen the forging of Chang Tie to the point of approaching Xuantie with their bare hands, developed magical materials such as transparent glass and sawdust ice, and even created a temperature measurement and pressure measurement method specially used for the process, how could the hydraulic principle she discovered go wrong?"

Hearing Master Arrow's question, Shan Wanjing wiped a handful of sweat from being close to the furnace, turned around and replied: "The next forging process, as long as the operation is correct, must be able to make excellent blades." ”

"Temperature measurement, pressure measurement exercises, ......" mentioned the names of these two strange exercises, the arrow master looked slightly dignified, revealing obvious admiration, because he understood the meaning of these two, and his heart was shaken:

"It turns out that these two unimaginable heirloom secret methods were actually created by Miss Zhao Qing? It seems that the prosperity of our craftsman industry will really come in the near future and play an irreplaceable role. ”

"You have determined several process concepts such as temperature, pressure, and hardness, combined with the melting and boiling point of water and the size of the object, and set a series of standards, which is undoubtedly an unprecedented innovation in forging and smelting technology, and the old man feels that his trip is worthwhile."

"Being able to see such a systematic process theory and speed up its development process, even if most of the pieces of black steel that the old man treasured are broken, it is nothing."

These words finally showed the master demeanor of the arrow master. He spoke with a pretentious demeanor, a frenzy and pride that flowed from his bones, and it was difficult to associate him with a man addicted to alcohol.

After saying this, the Arrow Master immediately regained his previous expression of disinterest in anything, and said tiredly:

"But no matter how magical this 'hydraulic forging' is, looking at the structure of its processing area, it is obvious that it does not have the ability to make steel wire bowstrings, and when tonight's experiment is over, let the more suitable Dongming faction participate in the research."

"Hehe, just look at it, don't be too surprised when the time comes!" An old craftsman of the Dongming faction interjected, showing his support and trust in the machinery on the side: "If you can't make a bowstring, can't you make an arrowhead?" ”

According to the information and detailed testing obtained by Zhao Qing, the so-called "black steel" is actually tungsten steel, also known as cemented carbide, and the material is worse than the dark iron and cold iron of Yusheng diamond, but through the special smelting method, you can get the "clear steel" known as the essence of black steel.

This kind of "clear steel" should be a material with a high degree of similarity to dark iron, the former is the fusion of black steel and pure spirit qi, the density is slightly lighter than that of black steel, but the strength is obviously better due to the influence of vitality on its internal structure;

The latter is generally the fusion of black steel and turbidity heavy gas, the density can reach five or six times that of ordinary iron, and because it generally comes from meteorite outside the sky, it usually melts a very small amount of solar gas, which is faintly red in the black, and has a strong magnetism.

Depending on the quality of its own material, the top can be compared with pure black iron, and the inferior can be enough to cover the level of black steel, and the melting point is lower than that of black steel, which is easier to forge.

Whether it is Qinggang, Xuantie, or cold iron, Xuanjin, they are all treasures that can be found, and it is not the same thing as Wugang, a metal with a fixed mineral source, because the latter has no upper limit on output and has the potential for industrialization.

For example, the reason why the Dongming faction was able to dominate the world's weapons industry was because it developed several tungsten mines along the coast of the Ryukyus and the East China Sea, as well as a larger number of high-quality iron ores with an astonishing output.

Generally speaking, craftsmen who can engage in the high-end forging industry and create "divine weapons" have the secret method of raising the temperature of the furnace with essence blood or true yuan, supplemented by the technique of true qi blasting, and in the case of sufficient fuel, they can often reach the level of two or three thousand degrees or even higher.

Although it is far from the ultra-high temperature of high-purity solar true fire that can reach 10,000 degrees, it is enough to meet the needs of modern smelting, and it is much higher than the smelting temperature of 15600 degrees Celsius.

However, as a martial arts world, although the smelting and forging of tungsten steel is more than ten centuries ahead of the previous life, almost comparable to the level of the early 20th century, the relevant craftsmen are still in the stage of empirical science, and the theoretical system is very imperfect.

In response to these defects, Zhao Qing popularized some relevant process theories for the first batch of Dongming School craftsmen, and tried to standardize their process flow, and developed several special exercises specially used for measuring data.

For example, the temperature measurement method is originally an internal power of the Yan system, and after many rounds of transformation, it can be calculated according to the operation speed increase effect of the true qi after heating, and the temperature of objects within a certain distance can be estimated by substituting a special formula;

The low temperature down to minus 60 or 70 degrees, up to the high temperature of 3 or 4,000 degrees, can take effect, and the error can be within five to ten degrees.

The high-end method used by Zhao Qing himself is to directly use mental power to perceive, supplemented by the wavelength of light and the blackbody radiation formula for calculation, which far exceeds the former in terms of accuracy and measurement range, but the difficulty of practice and calculation requirements are also much higher.

By mastering the more accurate temperature of the furnace, the success rate of the smelting and forging process can be significantly increased, and it will be much easier to teach the technique, and it can be optimized after repeated experiments.

And strengthening Chang Tie with bare hands is naturally Zhao Qing's method of "Gang Qi Refining Soldiers", so that after the material is tempered and strengthened by Gang Qi, even if it is no longer attached to Gang Qi, it is obviously beyond the original level in terms of strength.

According to her speculation, this strengthened material should be affected by Gang Qi and be in the most stable state on the stacking of molecular atoms, eliminating the defects and dislocations of the crystal, which is equivalent to the nanoscale materials of the previous life;

There is no need for high-grade materials such as dark iron and black steel, as long as you spend time quenching with Gang Qi and use pure iron alone, you can create a dislocation-free iron that is far stronger than ordinary iron by 100 times, so as to forge a divine weapon that cuts gold and jade.

As for the other "sawdust ice" mentioned by Shan Wanjing, it is a composite material made of sawdust and ice according to the so-called British "ice aircraft carrier" plan rumored by Zhao Qing in his previous life, which is stronger than most of the steel in the world, and is not easy to melt and has a low density;

In this way, temporary shields and armor can be easily resisted by arrows and blades, and play a huge role on the battlefield.

……

In the discussion of Shan Wanjing and Master Arrow, the group carefully opened the valve connecting the water flow, turned the stainless steel long rod for manipulation, and made the hammer head at the end have a majestic force of almost a thousand stones through hydraulic transmission.

According to the results of the craftsmen on the side to test the temperature of the furnace, several other craftsmen urged the real gas to enter the furnace while blowing the air, heated a piece of black steel that was put into the furnace by special pliers, slowly made it reddened by heating, and then sent it into the opening of the forging press.

Using the power hammer driven by water pressure, the black steel has been repeatedly folded and forged hundreds of times, and the force is quite uniform each time, and the almost perfect force and temperature treatment have been obtained, and the impurities in it have been gradually removed.

The soot and mist produced by burning coal and charcoal are transported to the area adjacent to the Yong'an Canal through a special exhaust pipe, which is difficult to see in the night.

If all goes well, the quality of these tools forged from black steel will be no less than any blade made of comparable materials in the past, marking the beginning of a standardized and industrialized era in which the forging industry can continue to make progress without the need for so-called "masters".

Excavate, smelt, and forge metals such as black steel in batches, and equip the surface of black steel weapons on a large scale, so as to create a powerful elite, so that even if Zhao Qing does not personally participate in the war of future expansion, the combat power of his own forces is enough to suppress all kinds of enemies;

So that when she finally left this world a few years later, she also had the technological advantage to suppress the whole world, and she could maintain the stability of the country without a large number of troops, so that others did not dare to think of conspiracy.

In addition to the research of cold weapons made of metal materials, Zhao Qing naturally also considered gunpowder weapons, and in the case of complete raw materials, after several tests, he rubbed out TNT explosives with his bare hands, and estimated that the innate good hands who cultivated special exercises could also be reproduced according to the correct process.

The chemical equation and related operations for the preparation of TNT are actually in high school chemistry textbooks, and she wrote them down, but Zhao Qing only knows the proportion of raw materials in the preparation of black powder, and her understanding is not as good as the former.

The TNT explosives that crush the black powder of the current era, as long as the quantity is sufficient, can completely threaten the masters of the great grandmaster level, and the lethality is extremely amazing, if it is widely used, it can be said to release the demon that buried the martial arts era.

With all in mind, she sealed the craft for the time being, preparing to conduct large-scale research when the world was peaceful. It's just that if you deal with the enemy in the Cold Weapon Era, a large number of powerful crossbows with hundreds of stones are enough to play a role in slaughter.

The power of tungsten steel armor-piercing arrows is estimated to be able to penetrate even the tanks of the previous life, and shoot them into the enemy's military formation, causing damage that can be imagined, it is estimated that one arrow can penetrate twenty or thirty people, except for the grandmaster equipped with top-level weapons, it is the result of one hit.

After observing not far away for a period of time and confirming that there were no mistakes in the operation of many craftsmen, Zhao Qing's heart moved slightly, knowing that today's experiment by night has basically been successful, and the first generation of hydraulic forging press can indeed be put into use.

A big plan prepared by myself based on high-end forging technology may indeed have the possibility of being successfully implemented after a period of time.

After watching and asking the craftsmen to summarize and make suggestions for improvement, it is time for him to leave another underground laboratory to conduct martial arts research related to the Buddha's relics and demonic energy.

A few days ago, under the design of a mastermind behind the scenes, Hui Ke was affected by the demonic qi and had a conflict with himself, and ended up with the Dharma relics and the heavenly monk relics being obviously damaged, and the energy of the Shakyamuni relics almost exhausted.

After this battle involving Shakyamuni's spiritual ability, he has accumulated a lot of experience and made breakthroughs in Confucianism, Buddhism, Taoism, and spiritual strength, mainly in the spiritual and spiritual realm to improve, and further in the ability to sense, and also cultivated the method of "Su Shitong".

Even the spiritual materialization that Xiaoyaozi cultivated based on the route of "form and spirit" has been preliminarily achieved, and he can condense pure spiritual power into a real and void body, and the quality of the spirit has been significantly improved.

Zhao Qing secretly thought in his heart, experienced the perception brought by the recent realm improvement, stabilized his current cultivation, and performed a "Su Shi Tong" on himself, wanting to explore his memories before his previous life, but he didn't get any results.

"'Su Shitong' failed again, at most, it can only detect the memories of the past life that has been awakened and clarified, and it can't go back to the past life at all. Is this because of the limitations of dreaming in this world, or is there a deeper reason? ”

Zhao Qing, who had already tried several times, was not surprised in his heart, but he was thoughtful, speculating that he might have some kind of particularity as a "traverser", which was different from other people who could generally be explored by the "Su Shitong" in their previous lives.

Theoretically speaking, the memory images sensed by the "Sushitong" are essentially the contents stored in the alayas of sentient beings. The reason why I can't find success is because of the special attributes of the alayas themselves.

Maybe in my previous life, I was in a world where I couldn't practice, and because of this, I lost the ability to store my memories, and even at that time, there was no such thing as reincarnation?

If I can't sense the existence of my past lives because I don't have a related past, what kind of impact will this have, and will it have a positive or negative effect on my practice?

Zhao Qing silently pondered all kinds of possibilities related to herself, and began the initial integration of the multiple systems she cultivated, trying to integrate them at a certain level and create her own cultivation method.

And just as she was studying martial arts while waiting for the end of the black steel forging, suddenly, an unusual slight sound came from the bottom of the well in the north of Xijiyuan, which attracted Zhao Qing's attention.

Someone is manipulating the mechanism in Yang Gong's treasure house, causing the sound to reach the secret entrance of the North Well?

There is a high probability that it will be updated normally tomorrow
