Of course, this is just an explanation of Nie Fei based on what he has learned and according to science. There are still many imperfections waiting for Nie Fei to explore and discover, in order to be more perfect. And the most important part is that Reiki is made of those atoms. For this, Nie Fei can't give an answer for the time being. But Nie Fei felt that his own set of ideas should be right.

......

Through these analyses, Nie Fei became excited. "If your own analysis is correct, then it is very likely that you are the only person in this immortal cultivation world who has mastered this kind of law. ”

Thinking that he was the first person in the first place, Nie Fei was really excited for a while. But soon, Nie Fei calmed down again, "Nie Fei, you have to calm down." There is a use in mastering these, and the most important thing is to apply them in practice. ”

As a result, Nie Fei began to think about how to use these theories to improve his cultivation. If you want to say that Nie Fei's head is alive, after a while, Nie Fei thought of one. "Reiki is the end group that is attached to various molecules, just like a tail on an animal, which is different but has a tail. The need for aura is like the need for that tail, so if you cut off the tail directly, won't you get the tail?"

A while ago, Nie Fei was worried that there was no spiritual spirit grass that provided spiritual energy in this hundred refining sect. If this method is feasible, then it is completely possible to rely on the spirit grass and still have a supply of spiritual energy.

Of course, cutting off the tail is just a metaphor for the image. This kind of end base of aura is something that can be cut by any sword, because the molecule is too small, how can the sword have a place to start. The sword that Nie Fei said was just talking about one method, and there were several methods. There is a method called the substitution method, which is to use another substance to replace the end base of Reiki. It's like if you want this tail, you have to prepare another tail, and when you cut it off, you have to put it on. There is a condition for this method, that is, the replacement tail, which must be more beautiful than the original tail, otherwise, the animal will not be able to do it, and no one wants to change an ugly tail.

There is also a method called elimination. Again, take the tail as an example, which is to cut off the tail at once, and if it is a dog, make it a bald-tailed dog. But this method also has conditions, that is, the tail of this animal must not grow too strong, otherwise it will still be cut off with great strength. Obviously, a dog's tail is not a good thing, preferably a gecko's tail, the kind that breaks at the slightest touch.

After thinking about it for a while, Nie Fei decided to use the first method, which was the substitution method. It's not that Nie Fei is so merciful that he has to change the animal's beautiful tail, but the second method is really more difficult than the first. Among so many animals, trying to find an animal like a gecko, whose tail is broken at the touch of a finger, is really like looking for a needle in a haystack, and it takes a lot of effort, and it is likely that nothing will be found.

The first method is undoubtedly easier. Just prepare the next beautiful tail, and then go and pick and see if there is a tail of that animal, which is not as good as the tail that you are preparing to follow. After choosing, cut it off with a knife and replace it with a new tail, and that's it. The reason why this method is easier is because after preparing a beautiful tail, you only need to choose the ugly tail, so that the range of choices is undoubtedly wider and the difficulty of operation is less.

......

For the next few days, Nie Fei had been in the house, trying to use this alternative method to prepare the aura.

The substitute he used, that is, the new tail is caustic soda, the scientific name is sodium hydroxide, and the hydroxide ions in it are very active. For many substances that contain aura, this is an even more beautiful tail.

Before that, Nie Fei went to Baicaotang again and bought some of the herbs that were common in this world. He bought a total of fifteen common medicinal herbs, all of which belonged to the most common varieties in the immortal cultivation world, which could be seen everywhere and in sufficient quantities. Only by selecting these herbs, if the replacement is successful, can they become the source of Nie Fei's stable aura.

According to this method, after Nie Fei's experiment, he found that out of the fifteen kinds of herbs, a total of five could replace the aura. Nie Fei was extremely overjoyed, he had finally prepared the aura he had been longing for, and he was naturally very happy. But what made him even happier was that he found that this method had worked. That is to say, his inferences about Reiki cannot be said to be completely true, but a large part of them are always correct.

But at this time, the smile on Nie Fei's face suddenly froze, and he thought of a question. That is, this method is actually very simple to operate. Throughout the ages of the immortal cultivation world, there have been so many alchemists, why hasn't anyone discovered that this method can prepare aura? Or is it that this method has already been discovered, but it is kept secret and not told others.

But Nie Fei then thought, even if someone discovered this method, what would it be? The person who discovered it must not know the principle, so he was destined to only use this method. And Nie Fei himself, this method is just one of the applications under the premise of the principle, and in the future journey of cultivating immortals, Nie Fei is bound to apply it more, more than those who can only use this method, more than a hundred times and a thousand times stronger. Therefore, even if there is such a person, there is no comparison with Nie Fei, and Nie Fei doesn't have to worry about this at all.

Moreover, Nie Fei came to the Hundred Refining Gate, and through what he saw and heard, he knew a little bit about the alchemy of the immortal cultivation world. He found that the alchemy of the immortal cultivation realm was all taught by the master, and the alchemy was carried out according to certain steps. The process is very rigid, and at the request of the Master, not a single small step can be done wrong. This method of alchemy has undoubtedly completely stifled the creative power and adventurous spirit of the Dan masters, and under this premise, which Dan master dares to put herbs and caustic soda together? They must have tried their best to avoid this from happening before it was too late.

As soon as he figured this out, Nie Fei didn't think about it.

Nie Fei picked out the five effective herbs, and drank the liquid rich in aura in turn, each taking a small sip, and selected the herb with the most aura among them.

Ganfeng grass, an extremely ordinary herb in the immortal cultivation realm, is one of the raw materials of three first-grade pills that have no great effect. The biggest feature of this kind of sweet phoenix grass is that it has no characteristics, it is no more ordinary, and this medicinal herb is also very common, whether it is in the wild, or in artificially planted medicine gardens, you can see the figure of sweet phoenix grass everywhere.

But it was this herb that Nie Fei tried, and found that it produced the most aura. It can be seen that even the most ordinary thing, the most ordinary person, in a specific situation, will burst out with super power.

Nie Fei picked up a sweet phoenix grass, held it in his palm, stared at it for a long time, and thought to himself: My future cultivation depends on you.
