Although alchemy is not over at this time, the process of alchemy has just begun. Chen Hui can't see how the aura refined from inner alchemy changes in the cauldron furnace and finally becomes the tonic alchemy.

However, Chen Hui has made it clear that the secret of alchemy lies not in the process of alchemy, but in the special skills of alchemy witches, and in the special cauldron for each alchemy wizard.

In this case, the whole process of alchemy naturally has nothing to tell the truth, because the core secret of alchemy is not alchemy.

However, it is true that the Qing emperor asked Chen Hui to watch the whole process of alchemy and explain the core secret of alchemy to Chen Hui. He wanted Chen Hui to compare his method of preparing pills and try to simplify the process of alchemy.

Since the Qing emperor wanted Chen Hui to try, he would naturally tell Chen Hui all the information about alchemy.

The process of alchemy is divided into four steps: blowing in, removing impurities, refining, and alchemy.

Chen Hui has seen the first three steps with his own eyes and knows them very well. At this time, he only needs jiedan's step.

Chen Hui couldn't see the change in the cauldron. He could only explain it by the Qing emperor.

What Chen Hui can clearly know is that from the beginning of refining to the end of alchemy, the wizard can't stop, because in the refining stage, the wizard completely sealed the cauldron furnace with his own aura, and this process must continue until the aura in the cauldron furnace finally changes into alchemy.

"The process of alchemy is completely opposite to that of refining." The Qing emperor said to Chen Hui, "refining is to transform inner alchemy into aura, which can be seen as a process of distribution, while jiedan is to condense aura into tonic pill again. This process is just the opposite."

After a pause, the green emperor continued: "the alchemy wizard seals the cauldron furnace with his own aura. When the refining is completed, he will probe the aura from the sealing place, that is, the joint of the furnace cover and the cauldron body, into the cauldron furnace, and then swim away with the cauldron body, completely wrapping the aura refined by the inner alchemy."

Chen Hui nodded silently. When the green emperor said this, Chen Hui already understood that the process of alchemy is actually the alchemy wizard wrapping the refined aura in the cauldron furnace with his own aura, doing something similar to compression, once again condensing the aura to the extreme, which leads to the reification of aura and turning it into elixir!

Sure enough, the next explanation of the Qing emperor confirmed Chen Hui's idea. Although the explanation of the Qing emperor was based on the world's view, it did use this compression method to compress the aura refined from the inner elixir into the tonic elixir again.

"In the process of alchemy, will the wizard's aura be consumed more than refining?" Chen Hui asked.

"No!" The green emperor slowly shook his head and said, "the refining process is harder than the jiedan process! The reason is that the aura contained in inner alchemy is slightly different from the aura cultivated by our witches. This difference leads to the process of refining, which is harder than that of jiedan. Jiedan only takes time, and the consumption of aura is not as much as that of refining. "

"What's the difference?" Chen Hui asked curiously.

"The inner alchemy is the thing that comes into being only after cultivation." The green emperor pondered for a moment and explained: "it's equivalent to refining into the body. Although it doesn't enter our human body, it's the animal body, but the difference is not big in essence. The aura that enters the animal body condenses into the inner pill. Therefore, the process of refining the pill is actually hard work, and it condenses into the tonic pill that we take again, Relatively speaking, it doesn't need to consume too much aura. "

Hearing this explanation from the Qing emperor, Chen Hui suddenly realized.

Inner alchemy is the product of animal cultivation, breathing and breathing into the body. It accumulates the aura bit by bit, and finally condenses into inner alchemy in the body.

It's a long process to accumulate aura bit by bit and condense into inner elixir. The inner elixir formed by it is very strong.

The process of refining is to restore the solid inner elixir to the aura state again, which will naturally spend more time with the wizard's own aura.

This kind of aura refined by inner alchemy is slightly different from the aura around. The difference is that these auras have been absorbed into the body once. Although they are animal bodies, they make the process of jiedan much easier.

"Can we refine the elixir that can improve our accomplishments?" Chen Hui asked at this time.

"Yes The green emperor nodded without hesitation and said, "it's just that the chance is not big. Most of the time, what appears is the Qi tonifying pill. For example, this pill, the final pill, that is, the refined pill, will basically only be the Qi tonifying pill used by the Jin people. There is almost no possibility of the pill of improving cultivation, because the quality of this inner pill is too low."

This inner pill is gray white, and its color corresponds to the white of Jin nationality.

It can be seen that the color of the inner pill corresponds to the refined pill, which family can use it.

Chen Hui has also seen several other alchemists these days. They use different colors of inner alchemy. Since the tonic pill made from this gray white inner alchemy is used by the Jin people, the other colors must be the same as those of the other four groups.

At this time, the Qing emperor continued: "only in one case will there be a pill to improve cultivation, not a Qi tonic pill."

"Is it the case that the quality of Neidan is extremely high?" Chen Hui asked tentatively.

The green emperor nodded silently and said, "only when the quality of Inner Alchemy reaches the seven level cultivation quality of the five ethnic groups of human beings, can there be the elixir to improve cultivation. And this kind of Inner Alchemy can only be refined by me. The sixth level alchemy wizard can't refine it, because the tripod furnace I use can refine the seven level quality inner alchemy."

After a pause, the green emperor said, "I haven't alchemy for a long time, mainly because I don't have high-quality internal alchemy. Next time, I'll alchemy for you personally. You can let those people know the news under appropriate circumstances."

Chen Hui nodded and asked no more questions.

Chen Hui had a thorough understanding of the whole process of alchemy. One day later, the alchemy ended. The gray inner pill produced a low-quality tonic pill used by the Jin people.

The pills made by other alchemists are also Qi tonic pills. There is no pill that can improve the cultivation. Therefore, the probability of the pill that can improve the cultivation is too low.

It's no different from having a good luck.

After the end of alchemy, Chen Hui went back to his residence, but the way that the wizard who wooed him and discussed with those witches came to find Chen Hui did not work.

In other words, they didn't send someone to contact Chen Hui.
