Red and blue stone, an ore that is not common in the immortal cultivation world, and is even less commonly used, is only used as an auxiliary material in a very small number of refining weapons and magic circles.

Red and blue stone has a characteristic, sensitive to temperature, with the change of temperature its own color will also change, the higher the temperature is the moon red, the lower the temperature is the bluer, at the same time the red blue stone is also extremely resistant to high temperature, because the material itself is found more near the crater, although there is no real research, but most people think that it is the eruption of the earth fire, there is a saying that just with the eruption of the earth fire, because the temperature is extremely high, so the red and blue stone is red, mixed with magma in one place, can not be found, only after its natural cooling, with the temperature drop into blue can be found。

Although red and blue stones are rare but not precious, the Instrument Spirit Sect has them, and Lin Zhuowen used the deposit he got back from handing over a Bigu Dan to exchange a palm-sized piece from the sect.

That's right, this is the otherworldly version of the thermometer that Lin Zhuowen found.

Lin Zhuowen tried it, and holding the red and blue stone in his hand can make it slightly discolored, that is to say, the lowest temperature that the red and blue stone can measure is lower than the human body temperature, Lin Zhuowen put the red and blue stone in the water basin again, and performed ice acupuncture on the water basin until all the water in it froze, but the result was a little disappointing, some time before the water began to freeze, the red and blue stone stopped changing color, that is to say, the lowest temperature that the red and blue stone thermometer can measure is above zero degrees in the Fahrenheit temperature that Lin Zhuowen is familiar with, which makes Lin Zhuowen's idea of unifying the temperature of the earth and the other world can only be lost, but this actually has little impact on alchemy, as long as a measurable and precise temperature standard is developed.

Using red and blue stone as a thermometer is not actually Lin Zhuowen's invention, Lin Zhuowen's computer has a lot of common sense knowledge, when he is looking for a solution to temperature measurement, he sees that in fact, the predecessors have tried in this regard, which mentioned that someone uses the color change of red and blue stone to mark the temperature.

However, using color to mark the temperature, there is a fatal shortcoming, the human eye is not sensitive to color changes, such as red, pink, pink, these together it is difficult to distinguish which is redder and which is more pink, not to mention other more subtle changes, of course, you can use the color card to get close to the reference, but the color card of the color card to be accurate, first of all, the saccade is very accurate, this is another problem, even in the earth with modern technology can not guarantee that the colored paint is blended twice to the exact same color, let alone in this world, and how to keep the color of the color card for a long time, This is another fatal problem, not to mention in a high-temperature environment like an alchemy refiner.

So this method with a lot of drawbacks has not been able to spread, but in Lin Zhuowen's opinion, these are not problems, through the guò computer, he can completely count the number of colors, not counting other color calculation methods, is the most common RGB method, that is, the red, green and blue three primary colors each made two hundred and fifty-six parts of refinement, so that only the RGB method can identify two hundred and fifty-six times two hundred and fifty-six and then multiplied by two hundred and fifty-six for a total of more than 16 million colors, red and blue stone has a large range of discoloration, even if it is enough to mark one degree of temperature with a colorAll Lin Zhuowen has to do is to convert these color numbers jù into decimal numbers jù for easy comparison.

Lin Zhuowen fixed the red and blue stone on the surface of the Dan furnace, in his opinion, it was enough to record the temperature of the furnace body, and it was inconvenient to put the red and blue stone in the Dan furnace on the one hand, and it might also affect the alchemy materials because of the nature of the problem.

Someone noticed Lin Zhuowen's actions, somewhat disdainful, this guy not only likes to spoil spirit stones, but also delusionally wants to use red and blue stones to mark the temperature, this method is known to many people, and has been tried, but no one can succeed, why do people always not give up?

Lin Zhuowen didn't care about them, at present, he still had three materials left in his hand for refining Bigu Dan, which was the last capital for his salted fish to turn over, and he had to deal with it carefully.

In order to record the initial temperature, the first furnace was completely in accordance with the last alchemy process, and it became a pill and a lower grade, disappointing those who were waiting for free listening.

The second furnace adjusted the temperature a bit, but it was obviously adjusted in the wrong direction, "bang-" the oven was fried, and the person waiting for the sound to hear it got what he wanted.

The third furnace was not fried, and one of the Cheng Dan was still inferior.

The two lower-grade Bigu Dan were handed over, and Lin Zhuowen took over the Bigu Dan refining task twice, and received four points of the refining materials of the Bigu Dan, but the result was three successes and one failure......

Lin Zhuowen didn't remember how many furnace Bigu Dan he had refined, and he didn't know how long he had been in the Dan Cave, after reaching the third level of Qi training, he needed very little sleep, even if he was occasionally sleepy, he only needed to rely on squinting to recover his spirit, so he didn't know how many days he had been here, he just roughly remembered that he seemed to have thrown two Bigu Dan into his mouth.

Lin Zhuowen didn't know, others can remember clearly, this alchemy madman actually stayed in the Dan Cave Hall for more than two months, and those who were always waiting to see jokes and wait for free to listen to them at the beginning gradually changed their views and changed their attitudes, very simply, as Lin Zhuowen's alchemy times increased, his fryer became less and less, and there has not been a fryer in the past month, and his success rate has also become higher and higher, and it is completely 100% later, even if it is the lowest level of Bigu Dan, this is also very rare.

Moreover, the most important thing is that the quality of the Bigu Dan refined by Lin Zhuowen is getting higher and higher, almost a month ago, Lin Zhuowen refined the medium-grade Bigu Dan for the first time, and in the following month, the probability of Lin Zhuowen refining the medium-grade Bigu Dan is getting bigger and bigger, and now almost all of the refining is the medium-grade Bigu Dan, and some people even saw Lin Zhuowen refining a high-grade Bigu Dan.

At the beginning, the other people in the Dan Cave Hall thought that Lin Zhuowen was crazy and stayed away from Lin Zhuowen, but now, not only did they gather in Lin Zhuowen's vicinity, but many people also went crazy, they wondered if such crazy alchemy could really improve the rate and quality of Cheng Dan, and many people also found red and blue stones to follow Lin Zhuowen's example and fix it outside the Dan furnace, wanting to record the temperature with this, but the consequence of this is that they all failed, and some even went bankrupt because of this......

Anyway, Lin Zhuowen seems to have suddenly become a legend in the Dan Cave Hall, every time the alchemy will be a group of people gather to watch, in fact, it is extremely taboo to do so, but Lin Zhuowen did not refuse the first disciple who asked to be a bystander, and then the others naturally followed suit, and politely said hello meaning that they wanted to learn to learn whether they could watch, and the unwelcome was to squeeze directly into the crowd, anyway, there were many people, and the law did not blame the public, not to mention, Lin Zhuowen never taboo others to watch.

It's just that when some people want to ask Lin Zhuowen about his alchemy skills, Lin Zhuowen can't say why, he can't say that his brother has a computer to calculate time and temperature, he can only use such mysterious and mysterious words as "look with your heart and refine with your heart" to prevaricate, but I am afraid of being serious about everything, but there are really a few disciples who have put their hearts into making some progress in alchemy, so Lin Zhuowen is even more legendary in the eyes of these disciples, and even the disciples who manage the sect's alchemy tasks here will occasionally take the time to take a look.

There is a reason for them to come to see Lin Zhuowen's alchemy, Lin Zhuowen's entire alchemy process is full of calmness, orderly, not hurried, when to add ingredients and when to control the fire, there is no hurry or slowness, as if he is not calculating the time, but time is waiting for him, so that people who watch can't help but have an illusion, this is not alchemy, but performance, or the kind of special art.

There are also many people who want to imitate Lin Zhuowen's flowing alchemy movements, but the result is naturally miserable, which makes them have to sigh: people are different after all.

Another month passed, and Lin Zhuowen really improved the quality of the pill to the top grade as everyone thought, and almost all of them were top grade, only occasionally due to the difference in the quality of the material itself, there would be a medium-grade Bigu Dan.

Although this was in other people's expectations, but when it really happened in front of them, it was still difficult to accept, although the top-grade pill was not difficult to refine, but such a high probability of appearance was unexpected, if it wasn't for Lin Zhuowen's previous appearance Xiàn laid the foundation for everyone's cognition, I am afraid that now someone will regard him as the reincarnation of a Dan Immortal......

What disappointed Lin Zhuowen was that the top grade seemed to be the limit of his refining of the Bigu Pill, and it seemed impossible to further refine the legendary best pill with medicinal properties beyond the limit of the pill itself, in his opinion, he had optimized the entire alchemy process to the best, and many of the fire control steps were directly written as program control, if this could not refine the best pill, it could only be said that refining the best pill also needed other special conditions, and it was not something that he could involve now.

Then Lin Zhuowen began to try to refine multiple pills at a time, from the small furnace to the medium furnace and then to the large furnace, which may take a lot of time for ordinary people to adapt to the adjustment, but for Lin Zhuowen, who has the aid of a computer life weapon to accurately calculate, it is unexpectedly easy, two or three days later, Lin Zhuowen furnace alchemy, a furnace can ensure at least twenty-five high-grade Bigu Dan, large furnace alchemy, because the amount of one time needs to be controlled, so the high-grade rate has decreased slightly, but the efficiency is many times higher, these Bigu Dan, Lin Zhuowen except for keeping what he eats, all the others are directly sold to the sect at a discount, so that the spirit stones in his storage bag suddenly increased, finally got rid of the tragic situation of struggling on the poverty line every day.

Bigu Pill is only the lowest-level pill, even with Lin Zhuowen's alchemy speed and quality, there will not be too many spirit stones that can be earned, so Lin Zhuowen began to take over the refining task of other pills, so the White Bone Pill, the Continuation Pill, the Miasma Avoidance Pill, the Heart Protection Pill and so on gradually became Lin Zhuowen's forte.

Of course, Lin Zhuowen also practiced several alchemy techniques given by Jian Conglu, although such complex alchemy techniques did not play a big role in the refining of low-grade pills in the Qi refining period, but it was not completely useless, Lin Zhuowen did not mind spending some time and spirit stones in the early stage to practice the proficiency of these skills, and the experience in the game was that the sooner the skills were practiced, the better.

However, these are actually not the pills that Lin Zhuowen really wants to refine, what he really wants to refine are the three pills that can improve the cultivation of the qi refining period, the Qi Benefiting Pill, the Earth Spirit Pill and the Eight Treasure Pills, but because the refining materials of these pills are relatively precious, the corresponding refining tasks issued by the sect also put forward requirements, a certain amount of pills of the same level must be refined, and a certain amount of pills of the same level must be refined, and a certain rate of pills and the quality of the pills must be guaranteed.

What Lin Zhuowen is currently doing is to meet these conditions as much as possible, Sun Xinghui's suspicions about himself will not be so easy to eliminate, maybe he will find out something at any time, and when the time comes, his strength will not be enough to deal with it, and the time left for him to improve his strength is not so generous.

"What are you all doing together, I want to buy some alchemy materials, why don't you even have the one in charge?" a coquettish voice sounded in the hall of the Dan Cave.
