Although Zixiao Palace has mastered the use of aura that is not available on the earth, the foundation of the weapon is still inseparable from metallurgy, and the foundation of the metallurgical industry is chemistry and basic physics. Pen ~ fun ~ pavilion www.biquge.info

But unfortunately, no one in the Shenzhou Continent studied these two disciplines.

The cultivation system of the Shenzhou Continent is a practical science similar to traditional Chinese medicine, and all the results are based on experience based on the accumulation of phenomena. That is, they know how to do it to achieve their goal, but they don't know why they get the result this way.

Of course, the monks are not really ignorant of the principles, and they are also studying some theoretical things, but this research has not always been the focus, and the lack of systematic basic research has led to slow progress and little success, and there are even many wrong theories. The only little result is still limited to the cultivation system itself.

In the branch of refining, the theoretical basis of the monks is even more difficult to see, and the refining of weapons is almost entirely based on experience. It is precisely because the monks do not understand the basic principles and only know how to draw scoops according to the gourd, so the inheritance efficiency between master and apprentice is extremely low, and it is even more difficult to develop new varieties of magic weapons, even if they want to improve it, they don't know how to start.

Like the group of people who followed Zhenyuan Shangxian to do research before, they were already the best group of sub-weapon masters in Zixiao Palace, and they almost represented the peak level of Zixiao Palace and even the Shenzhou Continent in terms of refining. However, it is such a group of people who can't even improve the pickling solution of the embryo.

Why?

Because I don't understand theory.

They know that acids can corrode metals, but they don't understand the exact process of chemical reactions, let alone how to avoid those outcomes that they don't want.

Compared with the systematic scientific research methods used by those scientific research institutes on the earth, Zhenyuan Shangxian's research methods are more like civil science research conducted by science enthusiasts themselves. This kind of research method often lacks theoretical guidance, and only relies on a half-understood theoretical basis and some application experience to conduct research as if it were a matter of chance. Hell if the success rate of such a research method can be high.

Tianyou is complaining about Zhenyuan Shangxian's research methods, and the experiment over there has begun step by step.

Although the method is very civilian, Zhenyuan Shangxian and they represent the peak research power of the Shenzhou Continent after all, and they still have a clear eye for experiments. However, Tianyou was taken aback when this experiment had just begun, because he saw Ye Sanshan actually come over with a porcelain bottle the size of a wine jar, and then poured out an oily liquid with a sweet fragrance from it.

"Wait. ”

Ye Sanshan, who was pouring oil, was stunned for a moment, and the amount needed was almost the same, so he simply put down the jar, and then looked at Tianyou suspiciously. "Is there anything that junior brother doesn't understand?"

Where did Tianyou have time to answer the question, he ran directly to the small bowl filled with grease and squeezed Ye Sanshan, and then carefully picked up the small bowl and sniffed it.

"Is this glycerin?"

"What is glycerin?" Ye Sanshan asked incomprehensibly. "This thing is a hundred flowers oil, which is a kind of oil that the master collects and refines the seeds that appear after the flowers are in full bloom. ”

Hearing this explanation, Tianyou did not give up his doubts. I smelled it again, and it was indeed the familiar sweet fragrance, but the color was a little wrong, and it was not exactly the same as the glycerin I had seen. After thinking about it, I found an iron tong from the side, and then poured a little grease from the bowl to the tip of the iron tong.

There is a ready-made stove in the workshop. Tianyou walked to the stove with the iron tongs and brought the iron tongs close to the mouth of the stove. The grease on the tongs was not ignited at first, and it did not look like it was burning very easily. So Tianyou handed the iron tongs inside. This time the reaction was quite obvious. Just listening to the sound of "poof", the grease on the iron tongs burst into flames instantly, and the flames in the furnace skyrocketed in an instant, and the flames that didn't have time to disperse even erupted from the mouth of the furnace.

Looking at Tianyou's movements, Zhenyuan Shangxian didn't react much, and Ye Sanshan explained to Tianyou later: "This flower oil is similar to ordinary oil, and it will burn, but it will take a little longer to ignite." ”

Tianyou had already confirmed what it was at this time, put the iron tongs into the water tank to cool it for a while, and then threw it aside, walked back to the table and said, "This is glycerin, but it is not pure enough, so it is a little red." Pure glycerin should be a colorless, transparent liquid that is thicker than that. ”

"Have you seen it before?" Zhenyuan Shangxian always thought that he had discovered this kind of oil, but he didn't expect that someone had already refined it.

Tianyou knew that Zhenyuan Shangxian in the Divine Continent should be the real first discoverer, but he still said: "Although the disciple is from Orion, he has also learned a lot from a Western Regions swordsmith when he was wandering around. This is a material used by the swordsmiths of the Western Regions. ”

"Are you from the Western Regions?" Zhenyuan Shangxian said thoughtfully, "They do have some strange things, but it's not strange. ”

After answering the question to Zhenyuan Shangxian, Tianyou began to check the other experimental materials that Ye Sanshan and Lu Meng had brought, because he probably already knew what caused the explosion before.

In fact, pure glycerin rarely explodes, and the stability is okay, but as far as God knows, many compounds of glycerin are explosives, the most famous of which is probably nitroglycerin, a high-risk explosive that can cause violent explosions by collision, extrusion, and heating.

Now that glycerol has been discovered here, it should not be difficult to find other compounds. Tianyou suspects that the previous explosion should have been the result of the glycerin-derived explosives they had created in the process of dispensing the reagents.

Looking at Tianyou's search, Zhenyuan Shangxian and the others were also very puzzled, so they simply stopped the experiment and looked at what he was busy with. Lu Meng couldn't help but ask directly.

Tianyou explained the properties of glycerin to them, and Zhenyuan Shangxian was surprised when he heard it, and hurriedly instructed Ye Sanshan and Lu Meng to help, pick out the materials needed in the test, and let Tianyou check them in the same way.

Sure enough, as soon as the things were sorted out, Tianyou immediately discovered the problem.

Using a clamp made of ceramics, he carefully picked up a piece of white substance, carefully distinguished the color, smell and other characteristics of this thing, and finally turned around and asked Ye Sanshan: "Senior brother." Is this saltpeter?"

Ye Sanshan nodded. "Yes, that's saltpeter. Could it be that this is what you said would explode when mixed with glycerin?"

Tianyou nodded at first, then began to shake his head again. Seeing that they didn't know what was going on, I could only give them a brief explanation.

"When saltpeter is heated, it produces two substances, one of which when it comes into contact with water to produce a strong acid called nitric acid. You need to heat it during your experiment, and it must be this process that decomposes the saltpeter, and the glycerin and other substances you use are not pure enough, and they contain water, which forms nitric acid. When nitric acid comes into contact with glycerin, it reacts quickly at high temperatures and explodes immediately thereafter. The reason why the explosion occurs in the middle of the experiment every time is that it takes time for saltpeter to decompose, and when you are halfway through the experiment, nitric acid is also produced. But there's one thing I still can't figure out. ”

Zhenyuan Shangxian and their experiment can be said to have entered a dead end, a group of people have been thinking for a long time and can't find a breakthrough method, such as today You can actually pour out the reason for the failure, and also explain the process principle so thoroughly, which makes Zhenyuan Shangxian excited. Suddenly, when he heard that Tianyou still didn't understand, he immediately asked, "Tianyou, what else do you not understand?" Say it and let's discuss it together, maybe we can find the answer. ”

Tianyou didn't sell it, and said directly: "It is said that after saltpeter is heated and decomposed, nitric acid will be produced as one of the gases." This gas should continue to rise when heated and expanded, and the temperature at which you heat it is so high that even if the raw material is impure and has moisture, when the saltpeter decomposes, the water should have been evaporated long ago. How exactly does this produce nitric acid?"

As soon as he heard this, Zhenyuan Shangxian suddenly laughed. "Hahahaha, Tianyou, I'll talk to Concubine Tian, how about transferring you to my Treasure Weapon Sect?"

Tianyou, who was analyzing the reasons for the failure of the experiment, heard this sentence coldly, and suddenly didn't react. "What did you say?"

"I said how about transferring you to our Treasure Weapon Sect?"

"Huh?" Tianyou looked confused. Isn't that what we're talking about? Isn't your mind jumping a little too much?" "This ......?"

"As long as you agree to join my Treasure Weapon Sect, I promise to accept you as my disciple immediately. Thinking that Tianyou was hesitating about gains and losses, Zhenyuan Shangxian directly began to dig people.

"This ......" After hesitating for a while, Tianyou still hugged his fists and said: "Thank you Zhenyuan Shangxian for raising love, but the disciple likes to move or not, if the disciple is always by the fire, study the production of magic weapons, I am afraid that the disciple will not be able to calm down." It's better to be like now, still studying in the Divine Soldier Sect, and when Zhenyuan Shangxian needs to come to help, he can give full play to his disciple's talents. I beg Zhenyuan to be enchanted. ”

This decision is the result of careful consideration.

He does have an advantage in refining weapons, after all, he has learned to forge swords on the earth, and he knows some knowledge of chemistry and physics, and the application in the refining field is definitely a huge advantage beyond the reach of the natives of the Shenzhou Continent. However, Tianyou thought more thoroughly.

The strength of the Treasure Weapon Sect lies in the making of weapons, but the knowledge learned by Tianyou is based on the knowledge of smelting and casting under the modern industrial system, and the application of the Treasure Weapon Sect requires the cooperation of many people and the accumulation of a long time. Therefore, if you join the Treasure Weapon Sect, Tianyou will delay a lot of time and wait for the gradual improvement of the supporting equipment. Moreover, he will also lose the opportunity to receive cultivation guidance in the Divine Soldier Sect.

However, the reverse is different.

Tianyou already knows a lot about making weapons, but what he lacks is the knowledge of the injection of aura, so even if he comes to learn a little occasionally, he can master the means of making weapons, and this does not delay him from learning combat skills and advanced cultivation methods in the Divine Weapon Sect.

Therefore, for Tianyou, making weapons can be learned as a hobby, and those courses offered by the Divine Soldier Sect are the most important. In this chaotic Shenzhou Continent, only by truly mastering the power can you settle down. Otherwise, once the battle between him and Moon Shadow deduced by the Immortal Buddha starts, even if he has a high level of weapon-making, he will still be able to die easily.

Of course, Zhenyuan Shangxian was unwilling, and persuaded a few more words, but Tianyou was resolute, and Zhenyuan Shangxian couldn't do anything about him. "Okay then! In that case, this matter will be put on hold for the time being, if you figure it out when you are willing to come to my Treasure Weapon Sect, I am always welcome. ”

Zhenyuan Shangxian didn't plan to give up yet, but still kept a hand, in case he had the opportunity, he would still attract Tianyou to transfer to the Treasure Weapon Sect.

After finishing the work of digging corners, Zhenyuan Shangxian began to explain his previous questions to Tianyou, and Tianyou finally understood why nitric acid was produced.

On the surface, it seems that the test equipment of Zixiao Palace is quite backward, and all kinds of open utensils are used, and it is said that gases and substances with low boiling points are evaporated during the heating process, but in fact this is not the case.

On the surface, Zhenyuan Shangxian and their equipment are indeed very backward, but in some ways, these things are a bit too advanced. The seemingly ordinary crucible actually had a fire spirit enchantment on it, which could absorb the flame aura in the high-temperature furnace used to make the device, and then form a sealing barrier to completely seal the crucible.

During the entire heating process, the crucible appears to be uncovered, but in fact, like the high-pressure reaction vessel, the inside is completely sealed. You don't want to get out of any gas, so the end result is not nitric acid in the crucible, but nitric acid vapor in the airtight barrier above the crucible.

Tianyou's previous inference was also incorrect. The explosion did not occur in the middle of the experiment, but at the end. After the heating is completed, the crucible is removed, and the flame enchantment needs to wait for a while before the energy is exhausted and disappears, but the nitric acid vapor in it is cooled first, and reacts with glycerin, and finally before the enchantment on the crucible is opened, the contents will explode first. Not only did it burst the crucible and form a large number of fragments, but it also ignited various flammable materials on the periphery. The fragments on Qingxu's body before were the fragments of the high-pressure crucible after the explosion, otherwise a simple explosion would not have produced so much power.

Originally, Zhenyuan Shangxian had no hope for this reagent experiment, but they didn't expect to get an unexpected surprise from Tianyou.

After explaining the problem of this high-pressure crucible to Tianyou, Zhenyuan Shangxian asked Lu Meng and Ye Sanshan to invite back the immortal leaders who had been experimenting together before.

After a group of people returned, they were all very puzzled why Zhenyuan Shangxian had to conduct another experiment so soon, just now when Lu Meng and Ye Sanshan went to inform them, they only said that Zhenyuan Shangxian planned to do another experiment, but they didn't say anything about Tianyou. These people are all wondering, what's the point of doing something that is already doomed again?

Although they were very confused, the Great Lord summoned them, and they still gathered, but the questions still had to be asked.

When Zhenyuan Shangxian and the others arrived, they were very excited to introduce Tianyou to everyone, which made these people a little overwhelmed, thinking that you called us all back just to introduce a beginner disciple to us?

Zhenyuan Shangxian was on the rise, and he didn't notice everyone's reaction, but fortunately, he quickly began to introduce the things that Tianyou said before.

Those who can engage in research and development with Zhenyuan Shangxian are all masters of this way, and after listening to the theory explained by Zhenyuan Shangxian, they immediately became excited one by one, so under the auspices of Zhenyuan Shangxian, a new experiment soon began.

Before, because there was no theoretical guidance, I couldn't find a research direction, so I could only try my luck and fool around. Now, with the theoretical guidance provided by Tianyou, and purposefully to improve, this efficiency is immediately different.

To complete this experiment, the first thing that needs to be done is to solve the explosion problem. Originally, this problem could not be solved because I didn't know why it exploded, but now it's very simple. Since the sealed Fire Spirit Enchantment will cause a large amount of nitric acid vapor to accumulate inside the cauldron, it is better to release it.

The fire spirit magic circle that was originally constant on the special crucible was directly destroyed by Zhenyuan Shangxian and was manually maintained by one of the immortal leaders. Of course, all he had to do was maintain the barrier, but he also needed to make a gap at the top of the barrier every few short hours. Because of the high-pressure environment in the crucible, once a gap appears, the nitric acid vapor floating under the barrier will be immediately ejected, so that the glycerin below will naturally no longer come into contact with nitric acid, and the explosion will not occur.

According to the method that Tianyou said, everyone successfully completed the production of this first step. After waiting cautiously for a long time, the contents of the crucible did not explode.

After confirming this result, Zhenyuan Shangxian and those immortal elders were very excited, and even the attitude of those senior brothers brought by those immortal elders towards Tianyou was obviously much better. When they first met before, these people were a little unhappy when they heard that Zhenyuan Shangxian summoned them for a junior brother, even if Zhenyuan Shangxian introduced those theories, they couldn't understand it, and seeing that Tianyou was so young, they naturally despised it. But now that it has been proved that Tianyou has real skills, the attitude of these senior brothers will naturally change immediately.

The experiment doesn't end here. What they needed was a special solution that could be pickled for the embryo, and the non-explosion only ensured that the experiment could continue, not that the experiment was fruitful. Of course, if you can conduct the experiment, the progress will naturally be faster, but this time it still failed, and the effect of the yellow-green solution that looks like snot in the end is terrifying.

Originally, they wanted to use this thing to eliminate impurities, dust, cracks, and pores on the surface of the embryo, but now they can burn through a finger-thick iron plate with just a little bit. God bless assures that he has never seen such a powerful acid on Earth in his previous life. If I have to say, there is a monster with strong acidic blood in the movie, and the solution they make is similar to the blood of that monster. Just a short time after their experiments were completed, the thing actually burned through the crucible. In the end, they couldn't even find anything to hold this "thick nose", because even ceramics could only be held up in front of this thing for a short time.

Although the experiment failed, Zhenyuan Shangxian and the others were not discouraged, but rather excited. For them, the result is already a huge progress, and they didn't expect to succeed at one time, but now they have this kind of "thick snot", which is better than an explosion, right?

Seeing a group of immortal elders busy discussing how to improve the potion formula next, Tianyou became interested in the "thick snot".

Whatever this disgusting-looking thing is, it's certainly true that it's super corrosive. For Tianyou, there is no waste in this world, and everything has its own value. It's like the elements found on the earth, there are so many types, but I haven't heard of any of them being completely useless.

This acid is useless to Zhenyuan Shangxian doesn't mean that it is useless to Tianyou, even if it can't be used to refine weapons, can it be used as a weapon. With the corrosiveness of this thing, if it were thrown out suddenly, what would happen to the people you came into contact with?

Taking advantage of the gap in their discussion of Zhenyuan Shangxian, Tianyou asked Zhenyuan Shangxian, and after making sure that they didn't want this thing, they began to study how to preserve this thing by themselves, otherwise even if Zhenyuan Shangxian didn't want it, he wouldn't be able to take it away. Until now, this thing still relied on the levitation technique released by one of the immortal chiefs to float in the air, not because I didn't want it to land, but I really couldn't find anything to hold it. The few containers that there were couldn't last long in front of this piece of snot, so Zhenyuan Shangxian didn't dare to let this thing fall to the ground at all.

As I said before, Tianyou is a traverser who understands the basic concepts of physics and chemistry, so although he doesn't know much, he knows the general direction.

This lump of "snot" is highly corrosive, and you can smell sour from a distance, so you can be sure that this thing is an acid, but it should not be a simple acid, but an acidic mixture, similar to aqua regia.

Now that you know that this thing is an acid, it is simple to reduce its corrosiveness.

Chemically, the easiest way to make certain substances that do not react chemically is to heat them, and if you want to reduce the corrosiveness of acidic substances, then the easiest way is to cool down. When the temperature drops, the activity of the chemical also decreases, and once a certain threshold is reached, the chemical that could have reacted violently becomes a substance that does not react with each other at all.

Since this snot is corroded by something, then freeze it into an ice lump, and I don't believe that it can be so corrosive at ultra-low temperatures.

The idea can be said to be simple, but the effect is exceptionally good. Because the Immortal Elders were all discussing how to improve the formula, the senior brothers they brought were now in a state of idleness and nothing to do. Hearing Tianyou say that as long as the temperature is cooled, the acidity of this thing can be suppressed, some people expressed disbelief, so the crowd was divided into three parts. Most people are skeptical, but neutral. The rest of the people were divided into two halves, half of which were led by Lu Meng, and they believed that Tianyou's method would definitely work. The other half is led by a senior brother he doesn't know, who thinks that Tianyou's method is too whimsical.

At the urging of everyone, a senior brother soon helped make a small porcelain vase with an ice enchantment.

To say that this refining tool is obviously a little inferior to the modern manufacturing industry on the earth, but in some aspects you have to admit that the refining tool does have great advantages.

Take this porcelain vase that Tianyou just got. Obviously, it is the size of a one-pound wine bottle, but the inside of this thing is made with a constant temperature barrier, as long as you don't take the initiative to intervene and don't cut off the supply of spiritual power, the temperature inside the bottle will always be maintained below zero. It's not impossible to make this kind of technology like a small refrigerator on earth, but it is obviously impossible to make it so small and so simple to make.

Looking at the speed of the senior brother just now, I don't know that I thought he just went to peel an apple.

Of course, the disadvantages of this bottle are also obvious. It has no way to collect its own spiritual energy to recharge, so it needs to constantly replenish its spiritual energy, not that the monk has to consume spiritual stones to replenish his own spiritual energy, anyway, as long as the external replenishment stops, the temperature inside will immediately get out of control.

In addition, there is no constant device for the temperature inside this bottle, and how low the low temperature can be depends mainly on the speed of spiritual power input. However, because of the characteristics of the Ice Circle itself, it will at least remain below zero, and as for the maximum state, this cannot be tested because there is no thermometer.

Anyway, this bottle is for testing, and everyone doesn't care about the roughness of the work, and directly asks Tianyou to pour the snot into it.

Judging from previous experience, such a thin porcelain vase will have to be burned through at most a stick of incense. Tianyou stuffed the "snot" into it and immediately began to input spiritual power, and soon he felt that the bottle in his hand became extremely cold, but in order to test it, he still desperately increased the output, and then there was an extra layer of hoarfrost on the outside of the bottle visible to the naked eye.

"Is it frozen?" Lu Meng asked a little anxiously.

Tianyou shook the porcelain vase in his hand, and immediately heard a clanging sound. It is clear that the lump of "snot" inside has been completely frozen. However, at this time, the temperature of the bottle was too low, and Tianyou's hands couldn't bear this low temperature, so Lu Meng could only contribute a substandard spirit stone to temporarily hold it.

The time of a stick of incense passed quickly, the porcelain vase was still intact, and everyone began to get excited. Because this is not a gamble, even the senior brothers who don't believe in Tianyou are actually happy to see Tianyou succeed, because once Tianyou's theory is confirmed, it will also be a help to them in the future process of making weapons. After all, there are many opportunities to deal with acid when building embryos. With this method, you can control the corrosiveness of the acid to a certain extent in the future.

Although it didn't burn through the porcelain bottle in a stick of incense, in the end, the bottle still didn't last to the end, but it did persist for a long time, and it was not scrapped until Zhenyuan Shangxian and the others discussed and did a second experiment.

After the second experiment, Zhenyuan Shangxian and the immortals also heard about the theory that Tianyou's low temperature can reduce the activity of acid, so they also came to see this bottle.

According to Zhenyuan Shangxian, this bottle is a waste product, and such a bottle can make that cloud of acid last for so long without burning through the porcelain bottle, so if you make a qualified bottle, you will definitely be able to seal that kind of acid for a long time.

Because it was not early, Zhenyuan Shangxian did not conduct a third experiment. The second experiment was still a failure, and this time there was no "snot", only a black mass of charcoal.

After letting the other immortals leave for the time being, Zhenyuan Shangxian couldn't do the experiment alone, so he simply changed his mood, and on a whim, he personally helped Tianyou make a frozen bottle.

Compared with the defective products that the senior brother came out of the temporary work, the ones taken out by Zhenyuan Shangxian were very different.

This porcelain vase was added to the five magic circles in one go.

The first layer of the circle is the Whirlwind Circle. A small cyclone is formed inside the bottle body, so that the liquid entering the bottle is suspended without direct contact with the bottle body, so as to solve the problem of strong corrosion. Of course, if you exercise vigorously, the liquid in the bottle will still touch the wall of the bottle, so freezing is still necessary.

The second layer of the circle is the Ice Enchantment, which uses ultra-low temperatures to reduce the corrosiveness of acid.

The third layer is the isolation array, which restricts the low temperature inside the bottle and prevents the bottle from conducting heat. In this way, the outside of the bottle will not freeze, and secondly, it can also reduce the consumption, so as not to cause greater aura consumption due to heat conduction.

The fourth layer is a strong magic circle, so that the porcelain vase is as hard as steel and will not be easily broken.

The fifth and outermost layer is the Spirit Gathering Array, which can automatically absorb the spiritual energy to supplement the consumption of the other four magic circles, so that there is no need for Heavenly Blessing to replenish the spiritual power of the bottle at all times, nor does it need to consume expensive spirit stones.

In addition, this Spirit Gathering Array made by Zhenyuan Shangxian can also adjust the power consumption, and control the temperature by adjusting the amount of spiritual energy input to the Ice Enchantment. It's not exactly one degree or two, but it's better to have an adjustment than none at all.

"Zhenyuan Shangxian, you are worthy of being the number one refining master in the world. I can now understand why the magic weapon you made is so expensive, and there are a group of people who rush to buy it. "After taking other people's things, Tianyou didn't hesitate to offer a bunch of sycophants, and Zhenyuan Shangxian who took the shot kept laughing proudly there.

"Hahahaha...... , I used to think that your doll is hard-working and talented, intelligent, and has excellent bones, but now it seems that this sycophant kung fu is not much better. Alright, stop slapping me on the back, come and see our experiments and give me some advice. ”

Even said "don't dare", Tianyou still quickly went over and discussed with Zhenyuan Shangxian. In the future, if he wants to do something, he will have to count on Zhenyuan Shangxian to help, and such a good opportunity to get closer to each other cannot be wasted.
