Chapter 1411

Rao Shiqing emperor has explained that this step needs to be repeated for a long time. Chen Hui did not expect that this repeated process is actually three days!

It doesn't take a long time to blow in, just heat the cauldron and clean it up, even if the blow in process is completed.

According to the calculation of time, the whole process of blowing in is about half an hour.

But the process of expelling the impurities of Neidan is not only three days, but also quite boring.

It takes about ten minutes to repeat each step of removing impurities, and the interval time of removing impurities is about half an hour to one hour.

Naturally, Chen Hui has doubts about this, and he will also ask the Qing emperor.

Through Qingdi's answer, Chen Hui understood what was going on.

For the inner elixir used by the alchemist, the continuous heating of the cauldron furnace is only ten minutes. Beyond this time, not only the impurities in the inner elixir, but also the inner elixir itself will be melted by the heat of the cauldron furnace.

This is the reason why it takes only ten minutes to remove impurities each time. Beyond this time, it will exceed the temperature limit of the endosulfan. Before the process of removing impurities is completed, the endosulfan will be destroyed.

Since this is the case, it is very natural that the process of removing impurities should be repeated again and again, until all the impurities in this inner pill are completely removed, and the rest will only be the inner pill containing aura.

In other words, only pure aura is left after removing impurities.

And the Qing emperor's explanation of Chen Hui is also quite detailed, so Chen Hui also learned more about removing impurities.

The higher the cultivation level of the five groups of human beings corresponding to Neidan, the less impurities it contains. The shorter the process of removing Neidan, the shorter the time.

On the contrary, the lower the cultivation level of the five groups of human beings corresponding to Neidan, the more impurities it contains. The longer the process of removing Neidan, because you need to constantly repeat this step to remove impurities.

In other words, the impurities are removed little by little. The more impurities contained, the worse the quality of endosulfan. The shorter the time of continuous heating temperature that can be tolerated, so we have to let endosulfan cool down after removing certain impurities, so as to repeat this step again.

The less the aura impurities contained in Neidan, the longer the time it can withstand the continuous heating temperature of the cauldron furnace, and the more impurities it can remove at one time. The time of removing impurities will naturally become very short.

On the third day, when the process of removing impurities was coming to an end, Chen Hui asked, "according to the Qing emperor, isn't the time of refining pills different?"

It's normal for Chen Hui to have this question. The time required for removing impurities from the inner pill is different, and the time for refining the inner pill should also be different.

The reason why Chen Hui has this doubt is that the Qing emperor said to Chen Hui in recent days that the whole process of alchemy needs to last about seven days.

It takes about seven days, which means that every alchemy takes about seven days. This is true of every alchemy wizard.

The green emperor shook his head with a smile and said, "it's not like this. Although the time to remove impurities is different, there are still the remaining steps, which are the process of refining the inner elixir with only pure aura and condensing it into Dan again. These two processes, namely refining and alchemy, will flatten the time again!"

After a pause, the green emperor continued: "it takes a lot of time to remove the impurities in the inner pill with more impurities. But more impurities means that the inner pill contains less pure aura, the refining time will be shortened, and the time to form the inner pill will be shortened. However, the inner pill with less impurities only has pure aura, and the refining time will be longer, and the time to form the inner pill will also be longer, On the whole, the time spent on alchemy is almost the same. The time spent on alchemy is about seven days. It's no faster than an hour or two, and it's no slower than an hour or two. "

One hour is two hours, one or two hours, that is, two to four hours.

The time for alchemy is about seven days. Taking seven days as the baseline, it will float up and down for two to four hours. In fact, the time difference is not much.

"I see." Chen Hui nodded and said.

At this time, it was getting dark. The green emperor said, "the process of removing impurities is almost over today. It will be over before dinner. After dinner, I'll go out!"

Chen Hui took out a small cloth bag from his body and handed it to the emperor. He said, "twenty pieces from a well is enough."

There is no doubt that what Chen Hui gave the Qing emperor was the pills he refined.

At this time, the emperor was told the dosage.

"Within six hours, drinking well water will have an effect. When the emperor went out, calculate the time." Chen Hui also warned.

The green emperor nodded silently, and understood Chen Hui's meaning. He said that the pills can only last six hours when they are put into the well water. Within these six hours, after someone drinks the well water, the medicine will appear.

More than six hours later, the pill lost its effect.

"Well water will boil, OK?" The emperor asked in a low voice.

"No problem." Chen Hui replied immediately.

The green emperor nodded and said nothing more.

This alchemy, the quality of the inner pill is basically the same, the process of removing impurities, the time spent is also similar.

The time estimated by the emperor was almost the same. Before dinner, all the alchemists stopped.

The alchemists also eat in the alchemy room. It can be said that when they are alchemy, they are really inseparable.

Some of the danfang rooms were empty, and the Qing emperor arranged for Chen Hui to have a rest in one of them.

Qingdi and Chen Hui had dinner together in the danfang and left alone. Before they left, they told the warriors to be on guard.

Naturally, Chen Hui would not make trouble at this time. After dinner, someone came to collect the dishes and chopsticks. He directly lay in Dan's room to have a rest.

There is a bed in the Dan room, which is for the rest of the alchemists.

Chen Hui won't be supervised by those brave men here. He can walk around at will. But at this time, Chen Hui will never walk around.

Chen Hui doesn't know when the Qing emperor will go out. However, Chen Hui knows that he will finish what he should do tonight.

What's more, according to the meaning of emperor Qing, during the alchemy, this may also be her only chance to go out easily, because tomorrow is the process of refining inner alchemy, and after the completion of inner alchemy, it is the time of alchemy. Emperor Qing must be present.
