The miracle doctor came down from the mountain and opened a restaurant to raise his daughter

Chen Ning had done some research on it before. This was the regular alchemy method of the demon clan. If he made slight changes to it and used it to refine Beast Spirit Pills, it would definitely be stronger than what he normally refined.

Moreover, it would be a pity to discard this batch of golden elixirs. Anyway, they were not dug out by him. Later, he would use this mixed demon inner elixir and spiritual herbs to refine it into beast spirit elixir, which would be absolutely powerful and applicable to all alien races.

Of course, human cultivators can also take it, but since it contains human golden elixir, Chen Ning did not interrupt and gave it to human cultivators to use.

Having made up his mind, Chen Ning decided not to make any more items. All that would be left would be some miscellaneous items anyway.

By the way, there are also gifts for the children that Chen Ning has not given out yet. I have sorted them out and put them aside. I will give them out tonight when I have time, which will make the children happy again.

When he started to refine the elixir, Chen Ning did not start from the low level, but started from the highest level eight grade spiritual medicinal materials. After all, his mental state was the best at this time. If he refined all the low level medicinal materials, his spirit would be more or less damaged, and he would not be able to truly judge his true strength.

Ten high-grade eighth-grade medicinal herbs were placed beside him, and he also found a batch of fourth- and fifth-grade spiritual medicinal herbs as auxiliary materials.

Chen Ning divided these medicinal materials into ten portions, which means that he could use them to refine ten furnaces of high-level pills.

As for whether he could reach the ninth rank, Chen Ning was not very sure, but he believed in his heart that he could do it.

At this time, Chen Ning had to thank his unreliable father again. If he hadn't left him the Hundred Herbs Mirror, he would not have been able to fully understand all the medicinal herbs in the world of cultivation, let alone use them to reasonably formulate pill recipes.

The ten furnaces of elixirs can be roughly divided into four categories: two furnaces of spirit-enhancing elixirs, two furnaces of spirit-restoring elixirs, three furnaces of healing elixirs, and three furnaces of spirit-restoring elixirs.

Although there are tens of millions of kinds of elixirs, they can be roughly classified into a few main categories. The different names are only because the names of the spiritual medicinal materials of some elixirs are different. After all, the nature and efficacy of many spiritual medicinal materials are very similar.

An embarrassing problem facing the cultivation world now is that many high-level pill recipes have been lost. It can even be said that the production of high-level pills has been cut off, and there are no king-level pills anymore. Therefore, the importance of Baicaojian has been infinitely magnified.

Chen Ning calmed down, put aside all distractions and started to make the elixir.

The upgraded strange fire alchemy furnace was condensed by Chen Ning. As he watched the alchemy furnace appear, Chen Ning's confidence in successfully refining the ninth-grade elixir increased several times.

First, a high-grade eighth-grade spiritual medicine material was thrown in without hesitation, and Chen Ning instantly felt a slight difference.

The smelting point of this eighth-grade spiritual medicinal material is much higher than that of the intermediate grade, and Chen Ning needs to control the alchemy furnace to increase the firepower and stability.

This is a Danhuo Alchemy Furnace, and a Purple Extreme Fire Alchemy Furnace at that. Otherwise, using an ordinary alchemy furnace, even the high-level Purple Smoke Alchemy Furnace given by Elder Yi, it would take at least two hours to refine this spiritual herb.

The longer the refining time, the greater the probability of accidents.

Under the refining of Chen Ning's alchemy furnace, in less than ten minutes, or to be exact, nine and a half minutes, the medicinal herb was completely melted into liquid, removing the rotten parts and leaving the essence, and finally only a ball of very pure medicinal liquid was left.

Seal this ball of medicinal liquid aside, and then refine the auxiliary medicinal materials.

Chen Ning put all four auxiliary spiritual medicinal materials of different qualities into it at once.

If it wasn't for his first time and he was not unskilled, Chen Ning would have put all the main and auxiliary herbs in together, and then melted them together, and finally could have directly integrated the medicinal effects.

When refining low- and medium-level pills, Chen Ning would throw everything in at once, and then the pills would be refined quickly, and the time could be reduced by at least two-thirds.

The auxiliary spiritual medicines entered the alchemy furnace and were all refined into medicinal liquids in less than a minute. They were directly blended under Chen Ning's powerful mental control. First of all, the medicinal effects of these auxiliary medicinal liquids reached a balance.

The next step is the most critical step.

It is to merge this auxiliary medicine liquid with the main medicine and balance their medicinal effects.

The pill can only be made when the degree of medicinal fusion exceeds 60%. However, if the pill starts to form at 60%, even if it succeeds in the end it will be the lowest quality ninth-grade pill.

Such a ninth-grade elixir is not as good as an eighth-grade elixir with a 90% fusion degree.

In Chen Ning's concept, 100% fusion is the minimum standard, and the most ideal is naturally absolutely perfect fusion.

Without any hesitation, Chen Ning controlled the two groups of medicinal liquid to merge together.

As a result, as soon as the medicine came into contact, a violent reaction occurred.

The main thing is that the high-level medicinal liquid seems to have its own ideas and does not allow the low-level medicinal liquid to be integrated into itself.

Chen Ning could only increase his mental output again, soothing or even forcing the medicine to calm down, and then accept the fusion bit by bit.

This process is relatively slow, and it consumes a lot of mental energy.

Fortunately, Chen Ning's current mental strength is comparable to that of the middle stage of distraction, so this kind of consumption is not a burden at all.

Although the degree of fusion of the medicinal liquid is getting higher and higher, the mental power consumed is getting higher, and Chen Ning also feels the gap between low-level elixirs and high-level elixirs.

This kind of fusion, without the assistance of the characteristics of the Danhuo Danlu, would be very difficult for Chen Ning. Not to mention perfect fusion, even reaching 100% would be very difficult.

Ten minutes later, the degree of drug fusion reached 60%, then 70%, and 80%...

When it reached 80%, the entire pill refining time had reached 40 minutes, while when Chen Ning refined the sixth or seventh grade pills, it only took him a dozen minutes.

And this is not the end. When the medicinal effect was integrated to 90%, the medicine liquid began to fluctuate violently. This was the rejection after the medicinal effect could not reach a balance. Even if Chen Ning's mental power was released to the extreme and he could only maintain a state of not collapsing, the last 10% could not be integrated together no matter what.

If it were an ordinary alchemist, he would decisively give up on fusion and start to condense the pill at this time. After all, a 90% fusion degree is already quite good.

But Chen Ning's pursuit of elixir is perfection, and he is very persistent, even paranoid.

It is better to let it fail completely than to achieve 100%.

The situation was getting a bit stalemate at this point, and Chen Ning started distractedly thinking of countermeasures.
