After all-round consideration, Chen Hui had already thought about the same thing. However, Chen Hui did not take it lightly. Instead, after dinner, he completely calmed down and thought about it all over again.

After confirming that there was nothing wrong with his idea, Chen Hui began to take out an inner pill and smash it with the method of water flying.

Of course, before using the Shuifei method, Chen Hui still followed his own way of thinking, first calcined the inner pill with the method of partition, so as to facilitate the better crushing of the inner pill.

Facts have proved that the method of calcination is still useful.

After calcination, Chen Hui easily smashed the inner pill.

Of course, this ease is relative to Chen Hui who is not an ordinary person, but a person with accomplishments. Even if it is a calcined inner alchemy, it is difficult for ordinary people to smash it. Chen Hui does this with aura.

After that, Chen Hui smashed the inner alchemy thoroughly with the method of water flying.

The whole process lasted for an hour. During this period, some magazines floated on it through the characteristics of the process. Chen Hui took them down and put them aside.

After the water flying method, the rest is very fine powder.

At this time, it is time to carry out the test process of removing impurities.

Chen Hui doesn't have a cauldron for alchemy. However, Chen Hui doesn't need a cauldron for alchemy. He only needs similar items.

What Chen Hui found was not bronze ware, but an iron pot.

Huo people are good at metallurgy. There is no shortage of iron in this world, and they seldom use bronzes. At this time, bronzes are more used for some rituals.

However, the iron content, or texture of this iron pot can't be compared with Chen Huilai's world iron pot.

Fortunately, there was no delay in using it. After Chen Hui set up the iron pot, he made a fire under it, using charcoal formed after burning.

Chen Hui did not directly put the powder of Neidan into the iron pot. Instead, he put the impurities that appeared when he smashed it with water.

One of the advantages of using charcoal is that there will be no smoke when charcoal is burned, so you can clearly see what the impurities are after heating.

Under Chen Hui's continuous stir frying, these powders slowly rise to smoke. With Chen Hui's stir frying, the smoke intensifies, but the impurities are less and less.

Although the impurities did not burn up, it can clearly draw a conclusion that the impurities can be volatilized by heating the processed medicinal materials.

This gives Chen Hui great confidence.

However, there are also problems, that is, with the continuous heating up of the iron pot, the smoke intensifies, which is not a good phenomenon and needs to be avoided.

Because the next step is to use the powder of inner alchemy, Chen Hui is not sure whether this situation will happen, and the alchemy wizard, when removing impurities, need to avoid the overheating of inner alchemy.

When Neidan is completely overheated, it will also cause Neidan to become Reiki again, just adulterated Reiki.

Now, endosulfan has been crushed, and its heat resistance should be lower than when it was a whole endosulfan before.

After thinking about it, Chen Hui decided to use the method of simmer to carry out the experiment, that is, in the heated iron pot, another layer of things were separated to transfer heat and heat the inner pill powder to achieve the effect of removing impurities.

Instead of looking for any special material, Chen Hui directly put a pottery pot in his room into an iron pot, and then put the powder of Neidan into a clean pottery pot.

After the pottery pot was heated slowly, the smoke rose steadily.

At this time, Chen Hui also began to turn the powder inside the pottery pot.

After a short time, there was no more smoke rising from the pot. Chen Hui took down the pot and looked at it carefully. Then he poured out the powder of inner alchemy. Compared with the time he poured in before, the powder of Inner Alchemy decreased.

Chen Hui waited until the pot had cooled down completely, then he put the pot into the iron pot again, and then he poured the powder of Neidan into the pot again.

Although the powder of endosulfan in the pottery pot was heated again, there was no smoke rising.

At about the same time, Chen Hui took down the pottery pot again and poured out the powder again. It seems that the powder has not decreased.

This process, Chen Hui repeated again, still no smoke rising.

By this time, Chen Hui can basically be sure that the impurities of Neidan should be completely removed.

At this time, it is already after midnight.

Chen Hui calculated the time. He had spent more than five hours, less than six hours, calcining Neidan.

It's time, that's three hours.

Chen Hui doesn't know whether the smashed inner pill can be refined into Qi replenishing pill again. However, Chen Hui is very confident that the impurities in the inner pill will be removed.

With this confidence, Chen Hui put away the powder and went to bed.

The next morning, Chen Hui went straight to the wooden palace to meet the emperor.

The Qing emperor asked Chen Hui to wait in the side hall. After the discussion, he went to the side hall to see Chen Hui.

Chen Hui didn't talk nonsense either. He presented the powder of Inner Alchemy to the emperor and explained how he did it.

After Chen Hui said this, he said: "please ask the Qing emperor to order the alchemist to try whether he can refine the powder of Inner Alchemy into aura. If he can refine it, it will have no effect on jiedan. Moreover, after refining, you can also feel whether the impurities have been removed, leaving only pure Aura!"

"It's according to the way you make herbs?" The emperor arranged for someone to call the alchemist into the palace. As he waited, he looked at Chen Hui and asked.

Chen Hui nodded and gave a positive answer.

"How long did it take?" The emperor asked again.

"About three hours." Chen Hui said truthfully.

"If you want to make high-quality inner elixir, I'm afraid it will be shortened at this time?" Asked the emperor.

"Yes, but not much." Chen Hui said: "the necessary steps still need to be taken step by step. It's just about the same as the whole process of alchemy, which takes about seven days

"I see!" The green emperor nodded his head with satisfaction and said: "three hours, compared with three days, has shortened a lot of time. As for whether it can be achieved or not, we will wait and see!"

When the emperor finished saying this, the alchemy wizard also arrived, not alone, but all the alchemy wizards in the King City!
