The two chatted for a while, and suddenly Yang Tianju's face became solemn, and he said, "Brother Nie, the two of us are no longer outsiders, there is something I want to ask in person." In fact, with the alchemy level of a brother, he could have become a Dan master a long time ago, and in this hundred refining sects, there should be a place for brothers. However, I really don't understand why my brother should condescend to Lin Qiao and prefer to be a disciple who fanned the flames. ”

Yang Tianju's words also slightly touched Nie Fei's heart. In fact, Nie Fei was already thinking about this problem. Indeed, as Yang Tianju said, being a disciple of Lin Qiao has caused a lot of inconvenience to himself. It's not that Nie Fei wants to be in a high position and have a good time, he doesn't have this idea for the time being. As Lin Qiao's disciple, the main problem was to refine the pill for him, which brought him a lot of inconvenience.

The real owner of this courtyard is still Lin Qiao. Therefore, Nie Fei is bound to not be able to act according to his own ideas in a big way. In case one is not careful, one day Lin Qiao breaks in, wouldn't he have discovered the secret. The best way is to become a Dan Master, at least a first-level Dan Master, so that you will have your own place. That's when you can let go of your hands and go big.

However, he is still only a cultivator in the Qi refining period, and he barely becomes a Dan Master, and he is not necessarily guaranteed. Of course, looking at Yang Tianju's appearance, if he wants to win himself over, he will inevitably spare no effort to protect himself. However, this kind of dependence on others, Nie Fei always felt that it was inappropriate, and the best choice was to wait until he became a monk in the foundation building period, and then became a Dan Master.

So far, Nie Fei has not found a way to make his aura grow rapidly. However, this matter is not as it was when he first came, and this matter has already been recognized. I believe that it won't be long before Nie Fei can become a monk in the foundation building period. At that point, it will be the time of independence.

"Senior, this is not the time, let's talk about it later. After a while, Nie Fei replied to Yang Tianju.

"Brother Nie, if there is any difficulty, you only need one sentence at that time, as a brother, I will definitely support you fully. Yang Tianju said sincerely. After this incident, Yang Tianju found out that Nie Fei was indeed a genius in alchemy, and he finally decided to cooperate with Nie Fei. Yang Tianju is an old oilman, he naturally knows that if you want to get benefits from others, you must first give benefits to others, mutual benefit, so that it can last for a long time. Therefore, his words were indeed out of sincerity.

Nie Fei smiled slightly and replied, "When the time comes, I will inevitably trouble your seniors." ”

......

After Yang Tianju left, Nie Fei lay on the chuang and continued to think about the question he had just been interrupted by Yang Tianju.

The question Nie Fei was thinking about was, what was the aura. Nie Fei came from a previous life, he was a chemist before he was reborn, so when he looked at something, he always wanted to judge it from its essence, that is, from the structure of matter.

Obviously, all matter is made up of the tiniest unit of atoms, so what is Reiki made of?

In this world of cultivating immortals, most of the materials are the same as the world Nie Fei has stayed in before, with mountains and water, grass and trees, stars and moons. The only difference is in the aura. In this world, Reiki is the root of immortal cultivators, and it is also the root of all immortal cultivation items. Therefore, this aura must be the most basic unit that constitutes the immortal cultivation realm.

It is precisely because of the aura that there are various realms of immortal cultivators, all kinds of fairy herbs, medicinal herbs, and various exercises to use aura. This qiē is based on aura. Assuming that there is no aura in this world, then this world must also be an ordinary world, and there will be no difference from the world where Nie Fei has stayed.

Therefore, if you want to study the immortal cultivation realm, you must first start with the aura. It's like learning chemistry by starting with the basic elements.

First of all, is this aura made of some new element, a substance that has never existed? Nie Fei believes that this situation should not be possible. An element depends on the number of protons in its nucleus, and in the scientific community of the earth, more than a hundred elements have been discovered, and the number of protons from low to high, no element has been missed. If the element to which the aura belongs, which is not within the scope of the periodic table, is a new element, it must be an element with a very large number of protons in the atom. This is impossible, because this element, which must be a heavy metal element, cannot form a gas. Moreover, the further the element, the more unstable it is, while Reiki is a very stable substance.

Therefore, Reiki must be a gaseous molecule composed of certain atoms. Through this analysis, it can basically be ruled out that Reiki is a gas composed of a single atom such as hydrogen, oxygen, nitrogen, etc., because Reiki is really very different from all these single-atom gases, and there is no such gas that has the characteristics of Reiki.

It can be judged that Reiki must be a gaseous molecule composed of several atoms combined. This molecule, in the conventional state, has gaseous properties, and the chemical properties are relatively stable, and can remain in a free state.

So, is the structure of this molecule complex or simple? This can be analyzed through the nature of the immortal realm. Obviously, the materials in the immortal cultivation world, including the herbs, materials, exercises, and so on of cultivating immortals, are just derivatives of aura. These derivatives all have a common characteristic, that is, they all have the property of aura.

This is a very important feature. If Reiki is a complex molecular structure, then its molecular chain must be very long, and the longer it is, the more unstable it is, and when it combines with other substances, this instability becomes doubly effective, and it is almost certain that it will break apart. The molecular structure is incomplete, how to maintain the original characteristics?

Therefore, it can basically be concluded that the Reiki molecule is a simple structure that can maintain its stability. After it is combined with other substances, it acts as an end group in the long molecular chain of this substance. In this way, this substance revealed the characteristics of aura and became a substance that could be applied in the immortal cultivation world.

To summarize below, Reiki is a simple molecular structure composed of several common elements. This molecule is very stable, but it has never been such a molecule on Earth. This molecule, adsorbed on various substances, combines with the molecules of the substance in the form of an end group to form a stable molecular structure. This new molecule, in addition to its own attributes, also shows the properties of aura, which can be used by immortal cultivators.
