House looked at Ruya and blinked his eyes, and did not refute, if they had read the five books that Ruya had integrated, they might still think that Ruya was bragging about pretending to be thirteen, but House, who had been studying what materials during this time, had to admit that if they could really make the things that Ruya wrote on miscellaneous items, this kind of hydraulic loom was really an unpopular thing.

It's just that this reality? The miraculous objects recorded on it that can go down to the sea and the sky really make him feel unreal, those are magical things that he can't even dream of.

The success of the hydrotextile machine greatly boosted the morale of the researchers in the institute, and further improved the development speed of the entire Black Rock City in the use of water, almost every day there will be one or two plans to transform into hydraulic operation are proposed, and then after a period of discussion, the feasible ones will be left for research, hydraulic crushers, hydraulic cranes, hydraulic pumps, etc.

Ruya was overjoyed to see that the research enthusiasm of the institute was so high, but the most happy thing was that the old man told him that the research of gunpowder had achieved some success.

Hearing this, Lu Ya immediately ran to the test site to watch the gunpowder experiment, and the prop of the experiment was a large-caliber cannon with a wall thickness of more than ten centimeters, in fact, this could not be regarded as artillery, but only a relatively strong launch canister.

The canister is about two meters long, 50 centimeters in diameter, and the inner wall diameter is only less than 20 centimeters. Since it was for experimentation, safety must be taken into account, so such an iron lump was created. With a weight of more than two tons, even with the strong physique of an orc, it would take at least the strength of a high-level wrestler to carry it.

Under Lu Ya's gaze, a large bag of black gunpowder powder was poured into the launch canister by the experimenters, and then a solid iron ball with a diameter about the same as the launch canister was also rolled in, and the corners of Lu Ya's mouth twitched when he saw this. The old man naturally noticed Lu Ya's expression, and couldn't help but ask, "Patriarch, what's wrong?"

Lu Ya turned his head to look at the old man and said seriously, "Uncle Tie, the safety issue in the research experiment is the top priority, gunpowder is a flammable and explosive thing, didn't you find that there was something wrong with them when they operated just now?"

"Uh..." "What's wrong" The old man was stunned for a moment, and then he took a closer look, and just when the experimenters were about to ignite, the old man patted his head and said quickly.

"It's friction, and friction between iron tools is prone to sparks!"

Seeing that the old man had understood, Lu Ya smiled silently, and then looked into the field.

There is a lead hole behind the barrel wall of the launch canister, and a lead wire about a meter long is pulled to a thick cement wall behind the launch canister, and the research institute responsible for ignition quickly squats behind the cement wall after igniting the lead with a fire fold, covering his ears with his hands and opening his mouth wide.

This is also recorded in Lua's book, opening your mouth wide when there is a loud noise can relieve the pressure on your ears and protect your hearing from being damaged by loud noises.

The lead burned very quickly, and after two breaths, the lead burned to the end, and a wisp of spark drilled into the launch canister, followed by a loud "boom~~", and the launch canister suddenly burst out a large puff of black smoke.

Lu Ya only felt that the concrete floor under his feet trembled, and then another loud "bang" came from a distance in less than a second.

Everyone looked for prestige, only to see that a tall cement wall about 100 meters in front of the launch canister suddenly collapsed and exploded, and the solid round bomb had been seriously deformed and fell behind the second cement wall like a steamed bun.

"Papapa~~" A series of applause came from behind the cement wall, and the research institutes applauded each other with joyful faces, and it seemed that they were very satisfied with the results of the test.

Although Lu Ya was also smiling, but he didn't mean to be excited, he walked quickly to the launch canister, and the researchers got out of the way when they saw Lu Ya coming, and their eyes were also full of longing.

Only these researchers know how powerful Lu Ya is, the things recorded in those materials are vast and profound, and they can be called miracles, but they are all from Lu Ya's own hands, and now the gunpowder alone has exploded with such power, which makes their admiration for Lu Ya go further.

Ruya walked to the opposite side of the canister, first observed the situation on the wall of the barrel, then reached in with a wooden stick and stirred it a few times, and then waved his hand to call two wrestlers to put on anti-scald leather and turn the canister upside down.

As the canister turned upside down, clusters of black powder fell out of it, piling up together for one-third of the amount of medicine at the time.

Seeing this, all the researchers gathered around, not knowing what Lu Ya was going to do.

"From the point of view of power, this kind of gunpowder is now competent, but the actual situation may be worse, these gunpowder are powdery, too much slag, not enough burning, and the temperature is too high, the gun chamber is too polluted, these various shortcomings make it difficult to really put into use."

Lu Ya's words made all the researchers look at each other, speechless, originally they thought they had been very successful just by looking at the power of the cannonball, but they didn't expect Lu Ya to say so many shortcomings in one mouth, which made them stunned and a little frustrated at the same time. They now also know the usefulness of this kind of gunpowder, if it is replaced with normal artillery, it is impossible to let this gunpowder go to the battlefield based on the shortcomings of these gunpowders alone, otherwise, when fighting, they will sprinkle urine and urine to cool down, and then they have to clean up the barrel, and if they can't do it, they can also blow up the chamber, and then it will be embarrassing for people to be crippled before they hit themselves.

"Don't be discouraged, how long have you been studying this, the standard I said is a mature gunpowder standard, others have used decades or even hundreds of years to study it, it is not easy for you to achieve this in just a few months, but science is rigorous, I will definitely raise questions, but for your encouragement is also necessary, the bonus will not be less, in addition, I recorded the nitrocellulose on the data, you test more, don't be afraid of consumption, science is the need for continuous experiments to produce the truth, the Blackstone tribe is your strongest backing。 Inform me to go down, add dinner tonight, let the city get two altars of special offerings, and I will have a drink with the big guy in the evening."

The atmosphere immediately warmed up after Lu Ya's words, and similarly, his attitude deeply touched these researchers who only knew about research, for those human beings who had just joined in, if they only revered Lu Ya in terms of knowledge, now they also admired Lu Ya's character.

The reason why Lu Ya has this attitude is also because he knows that even black powder is not something that can be made casually and qualified, and it can go to the battlefield.

Objectively speaking, the formula of black powder is not the main thing, black powder itself is a widely used gunpowder, different formulas, particle sizes, and loading methods will have different effects and functions, which Lu Ya has also recorded, and the group of researchers are also clear.

Taking the classic recipe as an example, fine-grained black powder can be used as a blasting agent, as well as a musket propellant and ignition powder, such as the early flintlock paper shell bullets, and the larger ones can be used as artillery medicine.

Of course, other formulas can also be used for artillery medicine, but Lu Ya has nothing to do with this, and it is already very good to remember the half-baked mantra of one nitrate, two sulfur and three charcoal.

In the past, Lu Ya had seen the situation of crossing into the other world to create gunpowder to dominate the world, and when he really studied it, he realized that things were far from being as simple as he imagined, even under modern conditions, many veterans with modern classic formulas are not easy to make military black medicine, the reason is that the process conditions cannot be reached!

It is said that modern society should be able to buy raw materials of the analyzed level, which is much better than in ancient times, but ordinary people still can't make qualified military black medicine.

The manufacturing process involves material purification, equipment, reaction environment (temperature, time), professionals, etc., and it is far from being invincible to take a classic formula.

For the time being, Lu Ya also felt that it was already possible, at least even if it was such gunpowder, it was estimated that no one on the entire continent would have it, and there were indispensable things that could be used for it.

As for nitrocellulose, or the mono-nitrocellulose used in modern ammunition, Lu Ya is just casually mentioned, even if Lu Ya's chemistry teacher died early, he also knows how incredible it is to create modern munitions in a world where the industrial base is almost zero, or rather, this possibility is almost impossible.

Luya's idea is very realistic, this otherworld is not catalyzed by ammonia, oxidation to directly produce pure and high-concentration nitric acid, and the preparation of the so-called nitric acid is achieved by sulfate saltpeter coheating, and the source of sulfuric acid is alum oil, alum oil comes from the original pyrite ore, containing many heavy metal ions and non-metal ions interference, so when it comes to nitric acid, we have to say sulfuric acid first.

As for how to refine concentrated sulfuric acid, how to use concentrated sulfuric acid and nitrate to react into nitric acid, and then refine it into a qualified concentration of nitric acid, and finally mix it with absorbent cotton to form a qualified nitrocellulose cotton that meets the military. This series of requirements requires a large amount of modern chemical knowledge precipitation, and mature refining tools to assist in order to complete, in the other world in a short period of time to successfully study nitrocellulose probability can be said to be infinitely equal to zero.

Although it was only the gunpowder group that made some achievements, when the meal was added, the entire research institute had a meal together, and of course, the two jars of special supplies could only be enjoyed by the gunpowder group alone. After a small celebration banquet, the fighting spirit of the researchers in other groups was also completely aroused, not for the incomparably rare and expensive special supplies and expensive bonuses, but the most important thing was the problem of face.

Since ancient times, there is no first martial arts and no second, as the best among ordinary people, everyone is secretly competing with each other, and no one wants to be left behind, so there will be a technological explosion in the next period of time.
