Fang Dalei didn't push the flames to the extreme at the beginning, alchemy is a delicate job, like boiling soup, it has to be simmered slowly, if it comes up quickly, the materials in it will be mushy and burnt.

When the entire Qiankun Ding began to turn red and hot, and the temperature in the furnace began to become uniform, Fang Dalei increased the intensity of the flame and raised the temperature of the Netherworld Flame, making the melting speed of the material gradually accelerated.

Of course, at this time, he didn't use all his strength, and he had to stay behind to do it with all his strength.

As the temperature in the furnace continues to rise, all the materials begin to melt into a liquid state, and of course, the melting rate is not the same because the temperature resistance of each material is different.

When the last material had all melted into a liquid state, Fang Dalei breathed a sigh of relief, this first stage was over, and the next stage was the second stage.

The second stage is to remove impurities from the liquid material. Although these materials are good and excellent materials, not all the parts inside are useful, just like the five-hundred-year-old Ganoderma lucidum, the outer circle of woodened shell is not of great use, although it also contains certain nutrients, but it is meaningless for alchemy, it can only be treated as waste residue, and what is really useful is the small group of essence inside.

Fang Dalei was only in his infancy at this time, and he couldn't do multitasking, so he could only try to control the temperature of the furnace, and then gradually remove the impurities in each material one by one.

The impurities that were removed were useless waste materials for Fang Dalei, and they were swept into the corners of Qiankun Ding by him, and they would all be disposed of after refining the Dan in the end.

But if he is willing to refine this useless waste and take it out, it will definitely be a miracle medicine for ordinary mortals to beautify their faces, nourish their health, and prolong their lives.

However, whether Fang Dalei was willing to help mortals refine this elixir was two words.

When all the impurities are removed, the remaining dozen or so liquid objects are all the essence left by the material, and the next thing to do is to blend all these liquids together to form a Gyokuro pill, and finally divide them into equal parts. Make it into a finished pill.

The most difficult time is when the ingredients are mixed together, because each mass of liquid is the essence, and the instinct will repel the other essences.

Just like the human body, the cells in the human body will instinctively reject foreign cells, and therefore have a war with the other party, if the human body cells win, then the human body will be safe and sound, if the other party wins, the person will be seriously ill. In the process of struggle, people will also have diseases.

The same is true of the current merger of medicinal essences. The various essences together repel each other, push each other, and refuse to be easily fused.

What Fang Dalei has to do is to use the method on the alchemy chapter of the "Nether Reincarnation True Technique" to blend the essence together, this process is very complicated and difficult, and if you don't pay attention to it, you will fail.

The consequence of failure is not only the loss of the essence of the medicinal herbs, but also the possibility of causing the explosion of the alchemy furnace.

Of course, Qiankun Ding is a spiritual treasure. It wasn't so easy to blow up, but even so, this furnace of elixir was considered useless.

Fang Dalei currently did not have the ability to control more than a dozen groups of medicinal essence at the same time, and he used the stupidest and most reliable method. One mass of essence after another, he first controlled one of the essences, let it slowly merge with the other essence, and waited until the two essences fused. Then use this fused essence to fuse the essence behind.

The fortresses are breached one by one, and so are the essences, and the energy consumed to do one at a time is far more energy than to build a bunch at a time. Everyone is going to come together.

Even so, after a while, Fang Dalei was still tired and sweating profusely, this kind of complex elixir was something he had never refined before, the blue medicine and red medicine he refined before were generally fused with two or three flavored medicinal materials, at most one time was only five flavored medicinal materials as materials, and the difficulty was simply a small amount compared to now.

Now more than a dozen materials are fused, and the difficulty is geometrically increased compared with before.

Time passed minute by minute, and the fusion had been carried out for more than half of the time, and there were still four clusters of essences left without fusion, and the essences that had been fused were obviously much larger than the remaining essences.

Fang Dalei carefully controlled the essence that had been fused together to move towards the next mass of essence.

At this moment, he suddenly felt that the defensive barrier he had set up had been touched, not by accident, but by someone deliberately hitting it.

Immediately, two more violent impacts occurred, causing the defensive barrier to tremble violently, but fortunately, the strength of the defensive barrier was strong enough to not burst.

Fang Dalei's mood was also affected in a slight, and he trembled slightly, just like that, causing the mass of liquid that was being controlled by his divine sense to fuse with a lot of medicinal essence to slam into the side with several essences that were about to be fused.

If they collide together, needless to say, this furnace of pills will definitely be scrapped, not only that, but there will also be a violent explosion inside the pill furnace, which will definitely make the lid of Qiankun Ding fly.

Fang Dalei hurriedly urged the Yuan Shen to the extreme, and forcibly stabilized the violently shaking mass of essence.

In this way, the impact of this large mass of essence made Fang Dalei almost spurt out a mouthful of blood uncomfortably.

Fortunately, he held back at the last moment, and successfully brought back the large mass of essence, keeping it away from the other clusters of essence that had not yet fused.

When all the essences had temporarily stabilized and there was no further movement, Fang Dalei frowned, carefully sensing the surrounding environment to see what was going on.

It's just that those few impacts came and went quickly, and at this time it was as if it had never happened, and disappeared without a trace.

If it hadn't happened just now, and it had greatly affected himself, Fang Dalei even wondered if the impact had happened.

"I don't know what's going on out there!" Fang Dalei frowned and thought that the barrier he had arranged was completely opaque to both sides, that is, it was equally defensive both internally and externally.

The purpose of this is to protect the hotel room from damage to the greatest extent possible in case the alchemy furnace explodes in case the alchemy fails, so as to avoid major disputes.

So at this time, Fang Dalei also didn't know what was going on outside the enchantment, and he couldn't remove the enchantment at this time and go out to see the situation outside, the top priority now was alchemy, this was the top priority. (To be continued......)
