Although Zixiao Palace masters the method of using spiritual energy that is not available on earth, the basis of making tools is still inseparable from metallurgy, and the basis of the metallurgical industry is chemistry and basic physics.

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

The cultivation system of Shenzhou Continent is a practical science similar to traditional Chinese medicine. All the results are based on the accumulation of phenomena. In other words, they know how to achieve the goal, but they don’t know why they will get such results.

Of course, the monks are not really aware of the principles. They also have some theoretical research, but research in this area has never been the focus. In addition, there is a lack of systematic basic research, so the progress is slow and the results are very little. There are even many wrong theories. The only result is still limited to the cultivation system itself.

In the branch of refining weapons, the theoretical basis of monks is even more difficult to read. Usually, refining weapons is almost entirely based on experience. It is precisely because monks do not understand the basic principles and only know how to copy them, so the inheritance efficiency between masters and apprentices is extremely low, and it is even more difficult to develop new varieties of magic weapons. Even if you want to improve it, you don’t know how to start.

Those who had been doing research with Zhenyuan Shangxian before were already the most powerful sub-made masters in Zixiao Palace. They almost represented the peak level of weapon refining in Zixiao Palace and even the Shenzhou Continent. However, even such a group of people could not even improve the pickling solution of the tool embryo.

What is the reason?

Because I don't understand theory.

They know that acids can corrode metals, but they don't understand the specific process of chemical reactions, and they don't know how to avoid results that they don't want.

Compared with the systematic scientific research methods used by scientific research institutes on the earth, Zhenyuan Shangxian and their research methods are more like civil science research conducted by science enthusiasts themselves. This research method often lacks theoretical guidance, and only uses a theoretical basis of only half-knowledge and some application experience to conduct research like a chance. This research method can make it look like a high success rate.

Tianyou was complaining about Zhenyuan Shangxian and his research methods, and the experiment had already begun step by step.

Although the method is very civil, Zhenyuan Shangxian and others represent the peak research power of the Shenzhou Continent, and they are still very concise when doing the experiment. However, Tianyou was startled at the beginning because he saw Ye Sanshan coming over with a porcelain bottle as big as a jar, and then poured out an oily liquid with a sweet fragrance.

"etc."

Ye Sanshan, who was pouring oil, was stunned for a moment. The amount needed was almost the same. He simply put down the jar and looked at Tianyou in confusion. "Is there anything that I don't understand when my junior brother?"

Tianyou had no time to answer the question, so he ran to the small bowl filled with grease and squeezed out Ye Sanshan, then carefully picked up the small bowl and sniffed it.

"Is this glycerin?"

"What is glycerin?" Ye Sanshan asked in confusion. "This thing is the oil of the hundred flowers, which is a kind of oil extracted by Master after collecting the seeds that appear after the blooming of flowers."

After hearing this explanation, Tianyou did not give up doubts. He smelled it again and found that it was indeed the familiar sweet fragrance, but the color was a little wrong, not exactly the same as the glycerin I had seen. After thinking about it, he found a pair of iron tongs from the side, and poured the grease in the bowl a little to the tip of the iron tongs.

There is a ready-made stove in the maker warehousing. Tianyou held the iron pliers and walked to the stove and approached the furnace entrance. The grease on the iron pliers was not ignited at first, and it seemed that they were not very easy to burn. So Tianyou handed the iron pliers into it again. This time the reaction was quite obvious. With a "puff", the grease on the iron pliers exploded instantly, and the flames in the furnace suddenly surged a lot, and the flames that had not had time to disperse even sprayed out from the furnace entrance. Thanks to Tianyou's flame demons, they were not burned by the flames.

Judging from Tianyou's actions, Zhenyuan Shangxian and the others did not react much. Ye Sanshan explained to Tianyou later: "This Baihua oil is similar to ordinary oil and can also burn, but it will take a little longer to ignite it."

Tianyou had confirmed what this was at this time. He put the iron tongs into the water tank and cooled for a while, threw them aside, walked back to the table and said, "This is glycerin, it's just not pure enough, so it's a little red. Pure glycerin should be a colorless transparent liquid, and it's a little viscous than this one."

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

Tianyou knew that the immortal Zhenyuan in the Shenzhou Continent should be the first discoverer, but he still said: "Although my disciple was a hunter, I had learned a lot of things with a Western Region Sword Forging Master while wandering around. This thing is a material used by the Western Region Sword Forging Master."

"Are people from the Western Regions?" Zhenyuan Xian said thoughtfully: "They do have some strange things, and it's not surprising."

After answering Zhenyuan Shangxian, Tianyou began to check other experimental materials brought by Ye Sanshan and Lu Meng, because he probably knew what the previous explosion was caused.

In fact, pure glycerol rarely explodes, and its stability is quite reasonable. However, as far as Tianyou knows, many compounds of glycerol are explosive products, the most famous of which is probably nitroglycerin. A high-risk explosive that can cause violent explosions can be caused by collision, squeezing, and heating.

Since glycerol was found here, it should not be difficult to find other compounds. Tianyou suspected that the previous explosion should be that they produced glycerol-derived explosives during the process of placing the reagents.

Seeing Tianyou looking around, Zhenyuan Shangxian and the others were also very confused, so they stopped the experiment and saw what he was busy with. Lu Meng couldn't help but ask directly.

Tianyou explained the characteristics of glycerol to them. When he heard it, Zhenyuan Shangxian was very surprised. He quickly asked Ye Sanshan and Lu Meng to help him pick out the materials needed in the experiment and let Tianyou check them the same way.

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

He carefully clamped a piece of white substance with a clip made of ceramic, carefully distinguished the color, smell and other characteristics of the thing, and finally turned around and asked Ye Sanshan: "Senior Brother. Is this saltpeter?"

Ye Sanshan nodded. "Yes, this is saltpeter. Could it be that this thing is what you said that it will explode if mixed with glycerin?"

Tianyou nodded first, and then began to shake his head. Seeing that they looked unclear, he could only give them a brief explanation.

"After heating of saltpeter, two substances will be produced. One of them will produce a strong acid called nitric acid when exposed to water. Your experiment needs to be heated, and this process must have caused the saltpeter to decompose. In addition, the glycerin and other substances you use are not pure enough, which contains water, which forms nitric acid. Nitric acid will react quickly at high temperatures and will explode immediately afterwards. The reason why every experiment explodes in half is that it takes time to decompose saltpeter. When your experiment is halfway through, nitric acid is also produced. But I still can't figure out one thing."

Zhenyuan Shangxian and his team's experiment can be said to have entered a dead end. A group of people thought about it for a long time but could not find a way to make a breakthrough. If You could actually come up with the reason for the failure today, and also explained the principle of the process so thoroughly, this made Zhenyuan Shangxian excited. Suddenly, he heard that Tianyou still didn't understand, and immediately asked: "Tianyou, what else do you don't understand? Let's talk about it together, and maybe we can find the answer."

Tianyou didn't keep it a secret and said directly: "According to the fact that saltpeter is heated and decomposed, one of the gases that will produce nitric acid should be. The gas should expand continuously when heated and expand, and the heating temperature of yours is so high that even if the raw materials are not pure and water, the moisture should have been evaporated long ago when saltpeter decomposed. How does this produce nitric acid?"

When I heard this Zhenyuan Xian, I suddenly laughed. "Hahaha, Tianyou, I will tell you to Concubine Tian, ​​how about transferring you to my Treasure Artifact Sect?"

Tianyou, who was analyzing the reasons for the failure of the experiment, suddenly heard this sentence and suddenly felt a little unresponsive. "Ah? What did you say?"

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

"Ah?" Tianyou looked confused and thought to himself that we are discussing experiments? Is your thinking a little too big? "This..."

"As long as you agree to join my Treasure Sect, I promise to accept you as my disciple immediately." Thinking that Tianyou was hesitating about gains and losses, the immortal Zhenyuan started to make a lot of information and poach people.

"This..." After hesitating for a while, Tianyou still clasped his fists and said, "Thank you, the disciples are happy to move but not quiet. If you want your disciples to stay by the fire and study the production of magic tools, you may not be able to calm down. It would be better to be like this now, and you are still studying in the Divine Soldier Sect. When the Zhenyuan Immortal is in need, you can come to help you with your disciples' talents. I beg Zhenyuan to beg you to be sure."

Tianyou's decision was a result of careful consideration.

He does have an advantage in refining weapons. After all, he has learned sword making on Earth and knows some knowledge of chemistry and physics. Application in the field of refining weapons 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 Artifact Sect lies in making tools, but the knowledge learned by Tianyou is based on the knowledge of smelting and casting under the modern industrial system. What is required to be applied in the Treasure Artifact Sect is the cooperation of many people and the accumulation of long-term time. Therefore, if you join the Treasure Artifact Sect, Tianyou will waste a lot of time waiting for the gradual improvement of the supporting tools. Moreover, he will lose the opportunity to receive training guidance in the Divine Weapon Sect.

But, the other way around is different.

Tianyou already knows a lot about making tools, but what he lacks is knowledge of injecting spiritual energy, so even if he learns a little occasionally, he can master the methods of making tools. This does not delay him from learning combat skills and advanced cultivation methods in the Divine Sect.

Therefore, for Tianyou, the tools can be regarded as a hobby to learn, and the courses offered by the Divine Weapon Sect are the top priority. In this chaotic Shenzhou Continent, only by truly mastering the power can one settle down. Otherwise, once the battle between the immortals and Buddhas inferred by Yueying started, no matter how high the tools are, he would still easily die from a dead end.

Of course, the Immortal Zhenyuan was unwilling to give up and persuaded him a few more words, but Tianyou was firm in his attitude, and the Immortal Zhenyuan had no choice but to do anything to him. "Okay! Since that's the case, this matter will be put on hold for the time being. If you understand it, I'll welcome you at any time."

Zhenyuan Xian was not planning to give up, but he still kept his hands. If he had the chance, he would still win over Tianyou to transfer to the Treasure Vessel Sect.

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

On the surface, the test instruments of Zixiao Palace are quite backward, and they use various open vessels. In theory, the gas and low boiling substances are evaporated during the heating process, but in fact this is not the case.

On the surface, Zhenyuan Shangxian and his friends are indeed very backward, but in some aspects, these things are a bit too advanced. The seemingly ordinary crucible actually has a fire spirit barrier on it, which can absorb the flame spiritual energy in the high-temperature furnace used for making the device, and then form a sealing barrier to completely seal the crucible.

During the entire heating process, the crucible seems to have no covering, but in fact it is like a high-pressure reaction vessel, with a fully sealed interior. No matter what gas you have, you can't imagine a slight slight. So the final result is not that nitric acid appears in the crucible, but that nitric acid steam appears in the sealed barrier above the crucible.

Tianyou's inference was also not correct. The explosion did not occur in the middle of the experiment, but at the end. After heating, the crucible was taken out. The flame barrier would have to wait for a while before it could exhaust its energy and disappear. However, the nitric acid steam inside was cooled first and reacted with glycerol. Finally, before the barrier on the crucible was opened, the things inside exploded first. Not only did the crucible explode and became a large number of fragments, but various flammable materials on the periphery were also ignited. The fragments on Qingxu's body were probably fragments after the explosion of the high-pressure crucible, otherwise the simple explosion would not have such great power.

Originally, Zhenyuan Shangxian and the others 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 all the immortal chiefs who had done the experiment together.

After returning, the group of people were puzzled why the immortal Zhenyuan had to conduct another experiment so quickly. When Lu Meng and Ye Sanshan went to inform them, they only said that the immortal Zhenyuan planned to do another experiment, but did not say about Tianyou. These people were all very strange. What's the point of coming up with something that was doomed to fail again?

Although they were very confused, the Great Lord summoned them and they gathered together, but the question still needs to be asked.

Zhenyuan Shangxian and others were all here and excitedly introduced Tianyou to everyone, which made these people a little at a loss. They thought you called us all back just to introduce us to a disciple who had just started to get to know us?

Zhenyuan Shangxian was in high spirits and did not notice everyone's reaction. Fortunately, he soon began to introduce what Tianyou said before.

Those who can do research and development with Zhenyuan Shangxian are all masters of this. After listening to the theory explained by Zhenyuan Shangxian, they were immediately excited. So under the auspices of Zhenyuan Shangxian, a brand new experiment began soon.

Before, because there was no theoretical guidance, I could not find a research direction and I could only do it as a chance. Now with the theoretical guidance provided by Tianyou and I can make purposeful improvements, the efficiency will immediately be different.

To complete this experiment, the first thing you need is to solve the explosion problem. Originally, this problem was unable to be solved because you didn’t know why it exploded, but now it is very simple. Since the sealed fire spirit barrier will cause a large amount of nitric acid vapor to accumulate in the crucible, release it.

The fire spirit magic array that was originally constant on the special crucible was directly destroyed by Zhenyuan Shangxian, and was changed to be manually maintained by one of the immortals. Of course, what he had to do was not only maintain the barrier, but also to create a gap at the top of the barrier every short time. Because of the high-pressure environment in the crucible, once the gap appears, the nitric acid vapor floating under the barrier will be sprayed out immediately, so that the glycerin below will naturally no longer contact with nitric acid, and the explosion will not occur.

According to the method mentioned by Tianyou, everyone successfully completed the first step of production. They waited carefully for a long time, and in the end, the substance in the crucible did not explode.

After confirming this result, the Supreme Immortal Zhenyuan and the Immortal Chief were very excited, and the attitudes of the senior brothers brought by the Immortal Chiefs towards Tianyou were obviously much better. When they first met, they were a little unhappy when they heard that the Supreme Immortal Zhenyuan summoned them for their junior brothers. Even if the Supreme Immortal Zhenyuan introduced those theories, they didn't understand them very well. In addition, seeing that Tianyou was so young, they naturally looked down on him. However, now the facts have proved that Tianyou has real skills, and the attitude of these senior brothers naturally changed immediately.

The experiment has not ended here. What they need is a special solution that can pickle the embryo. Not exploding only ensures that the experiment can continue, not that the experiment has achieved results. Of course, if you can conduct the experiment, the progress will naturally get faster, but this time it failed, and the yellow-green solution that looks like a 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 the things they made can burn through a finger-thick teppane with just a little bit. Tianyou promised that he had never seen such a powerful acid solution on Earth in his previous life. If he had to say it, there was a monster with strong acidity in the movie, and the solution they made was similar to the blood of the monster, corroding whatever they saw. Just a moment after their experiment was completed, this thing actually burned the crucible. In the end, they couldn't even find something to hold this "thick snot", because even the ceramics could only be forcibly supported in front of this thing for a short time.

Although the experiment failed, Zhenyuan Shangxian and the others were not discouraged, but were quite excited. For them, it was already a huge improvement to be able to produce results. They didn’t expect to succeed in one go. Now, it is better to have such a "thick snot" than an explosion?

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

No matter what this piece of thing that looks disgusting, it is certainly true that it is super corrosive. For Tianyou, there is no waste in this world, and anything has its own value. Just like the elements found on the earth, there are so many kinds, but I have never heard of which one is completely useless.

This acid liquid is useless to Zhenyuan Shangxian and others, but it does not mean it is useless to Tianyou. Even if it cannot be used to refine weapons, can it be used as a weapon? With the corrosiveness of this thing, if it is thrown out suddenly, what will happen to the person you come into contact with?

Taking advantage of the discussion between Zhenyuan and the Immortals, Tianyou asked Zhenyuan and the Immortals. After confirming that they wanted this thing, they began to study how to preserve it by themselves. Otherwise, even if Zhenyuan and the Immortals didn't want it, he wouldn't be able to take it away. Until now, this thing is still floating in the air by the floating technique released by one of the immortals. It's not that I don't want it to land, but I really can't find something to put it in it. The only containers can't last long in front of this snot, so Zhenyuan and the Immortals didn't dare to let this thing land.

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

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

Since you know that this thing is acid, it is easy to reduce its corrosion.

Chemically, the easiest way to react between certain substances that do not undergo chemical reactions is heating. If you want to reduce the corrosiveness of acidic substances, the easiest way is to cool down. When the temperature drops, the activity of chemical substances will also decrease. Once a certain critical point is reached, the chemical substances that may have undergone severe reactions will become substances that will not react with each other at all.

Since this snot corrodes whatever he sees, he will freeze it into a lump of ice. I don’t believe that it can still be so corrosive under ultra-low temperatures.

This idea can be said to be very simple, but the effect is extremely good. Because the immortal masters are discussing how to improve the formula, the senior brothers they brought are now in a state of idleness. Listen to Tianyou that as long as the cooling can be reduced, some people expressed disbelief, so the crowd was divided into three parts. Most people were skeptical, but remained neutral. The remaining people were divided into two halves, half led by Lu Meng, and believed that Tianyou's method would definitely work. The other half was led by a senior brother whom he didn't know, thinking that Tianyou's method was too whimsical.

Under everyone's urging, a senior brother soon helped to make a small porcelain bottle with an ice barrier.

To be honest, this refining weapon is obviously inferior to the modern manufacturing industry on earth, but in some aspects you have to admit that refining weapon does have great advantages.

Take the porcelain bottle that Tianyou just got for example. It is obviously the size of a one-pound wine bottle, but the inside of this thing is a constant temperature barrier. As long as you don’t actively intervene and do not cut off the supply of spiritual power, the temperature in the bottle will remain below zero. This technology that is equivalent to a small refrigerator is not impossible on earth, but it is obviously unlikely to make it so small and so simple to make it.

Judging from the speed of the senior brother just now, those who didn't know thought he just had to peel an apple.

Of course, the disadvantages of this bottle are also very obvious. It has no way to collect spiritual energy and recharge it by itself, so it needs to constantly replenish spiritual energy. It is not that the monks use their own spiritual energy to replenish spiritual stones. Anyway, as long as the external replenishment stops, the temperature inside will immediately lose control.

In addition, there is no constant device in the temperature in this bottle. The degree to which the low temperature can be mainly depends on the speed of the input spiritual power. However, because the characteristics of the ice array itself will be at least below zero. As for what state it can reach, it cannot be tested because there is no thermometer.

Anyway, this bottle was for testing, and everyone didn't care about the roughness of the work, so they directly let Tianyou pour the snot in.

Judging from previous experience, such a thin porcelain bottle would be burned through at most one stick of incense. Tianyou immediately began to input spiritual power after stuffing the "snot" in. Soon he felt that the bottle in his hand became extremely cold, but in order to test, he still tried hard to increase the output, and then there was a layer of white frost on the outside of the bottle that could be seen with the naked eye.
To be continued...
