After he left Qingdi's dormitory, he still walked along the tunnel with Chen Hui. When he returned to Chen Hui's residence, he told Chen Hui not to take it lightly before he left the King City of Mu nationality.

There are at least 20 days left for the next alchemy. Chen Hui has nothing to do during this period.

To be exact, there is no need to think about Prince Chang.

Because Chen Hui had more information about alchemy, he didn't tell Prince Chang all about it.

As a matter of fact, Chen Hui basically mastered the secrets of the wood family's Alchemy.

The only thing I don't know, or I can say I haven't seen, is that the Emperor himself made the alchemy.

As for the alchemy, the Qing emperor also had an advice. He hoped that Chen Hui could combine his method of making pills to see if he could simplify the process of alchemy.

In the following period of time, besides teaching medical skills and herbal medicine knowledge, Chen Hui was thinking about this matter.

Now that you are familiar with the process of alchemy, it is very simple to think about it.

The first step of alchemy is to turn on the stove, which can be directly skipped, because turning on the stove is just to clean the cauldron used in alchemy. Chen Hui's medical skills, or the method of preparing pills, have no help in this step.

The next step is to remove the impurities. This step is to remove the impurities of Neidan, leaving pure aura. This is a bit similar to Chen Hui's processing of medicinal materials. Processing of medicinal materials is to remove the toxicity of medicinal materials, leaving only the medicinal properties.

Then there is the process of refining, which is a reverse process. The formation of inner alchemy is the condensation of aura, while refining is the reduction of Inner Alchemy to aura again.

Chen Hui thought about this process carefully. His method of preparing pills and processing herbs are not similar to this process, and should not be helpful.

Although in Chen Huilai's world, there are many medicines that have been made into granules. When they are taken, they are brewed with water, but there is no comparison.

Because these drugs, which are made into granules, are not formed by gas when they are formed.

Finally, it's the process of making pills, that is, condensing the refined aura into pills again. This is another process that Chen Hui can't help.

Or it can be said that Chen Hui can not simplify the process.

Obviously, Chen Hui didn't think deeply at this time. Instead, he first considered the four steps of alchemy, and found out what might be helpful, that is, what might be simplified.

The second step is most likely to be simplified and feasible.

Simplification is not the same as removal!

Of course, if it can be simplified to remove this step, the effect is the best.

But Chen Hui doesn't think so.

Chen Hui believes that the greatest possibility and feasibility is to shorten the process of removing impurities and the time required.

For example, it takes three days for alchemists to remove impurities, and Chen Hui can simplify it to two days, which is a kind of progress.

Only by finding the right direction and making progress through experiments, can we further carry out more effective simplification research.

In other words, we have to prove the feasibility first.

However, this involves another thing. Chen Hui needs raw materials and raw materials for alchemy.

Raw materials are the inner elixir. Chen Hui can only explain the situation to the Qing emperor. Without raw materials to do experiments, everything is in vain.

The Qing Emperor didn't say anything. He gave Chen Hui three inner pills.

These three inner elixirs are the same as the inner elixirs when Chen Hui watched alchemy last time. They correspond to the inner elixirs of the third-order cultivation. However, these three inner elixirs are of three colors, corresponding to three of the five ethnic groups. The alchemy produced must also be used by the three ethnic groups.

However, the Qing emperor only gave Chen Hui three inner elixirs, which means that there are not many inner elixirs in the reserve of Mu nationality.

Because Chen Hui is very clear that Qingdi is a practical emperor, and Chen Hui has explained the situation to Qingdi. Without Neidan to do the experiment, it is impossible to know whether it can simplify the process of removing impurities.

What's more, Chen Hui made it quite clear that he was not sure about the two processes of refining and alchemy, and he did not think that the two processes could be simplified.

The only feasible process is to remove impurities.

Practical leaders, when they hear that they need raw materials for experiments, are bound to give raw materials.

In the case of sufficient supply of raw materials as test objects, we will certainly not be stingy.

The Qing emperor only gave three inner elixirs, which only means that there are not many inner elixirs in the reserve of the wood family.

In this case, it is quite generous to give Chen Hui three inner pills.

When Chen Hui got the three inner elixirs, he also made a promise to the Qing emperor. After he went back, he would certainly consider carefully, and then he would take the inner elixir for an experiment. He would not blindly do the experiment.

In other words, Chen Hui has to be careful about how to use and test the three inner pills.

When Chen Hui returns to his residence, his first consideration is the whole process of removing impurities.

In this process, the alchemist needs to wrap the inner elixir with aura and rotate in the cauldron furnace. Whenever the inner elixir reaches a certain degree, that is, the heat of the inner elixir reaches a certain degree, he needs to stop, take out the inner elixir, wait for the inner elixir to cool down, and repeat this step of removing impurities again.

There is no doubt that Nathan is afraid of the high temperature.

After Chen Hui thought about this, he immediately went to the Mu nationality palace to see emperor Qing and asked what would happen if Neidan overheated in the process.

The Qing Emperor gave a very positive answer. The overheating of inner alchemy is actually the process of refining. In other words, the overheating of Inner Alchemy will turn into aura again.

However, this kind of aura has impurities, not pure aura. It can't form a pill.

In other words, if the impurities are not removed thoroughly, the inner alchemy will overheat, which will turn the inner alchemy into aura again. This aura contains impurities, which will lead to the failure of alchemy.

After hearing the affirmative answer from the Qing emperor, Chen Hui had a clear idea. When he went back to his residence and looked at the three inner pills again, he had a little idea. The way he processed the medicinal materials and the process of removing impurities in alchemy also had more places to combine.

After making sure that he had understood the whole process of removing impurities, Chen Hui began to think about the method of processing medicinal materials.

There are also many ways to process medicinal materials, and the whole process of alchemy is to use the cauldron furnace, and the cauldron furnace is heated by fire. Chen Hui only needs to consider whether the same way of alchemy, the method of processing medicinal materials that needs heating, can remove impurities, and the possibility of higher efficiency!
