Ye Dong's spiritual sense entered the interior of the purple flame dragon fire, and what appeared in front of him was a purple-red world, and even in the state of spiritual consciousness, he could feel a wave of heat rushing towards his face.

It is a bit similar to the internal space of the medicinal herbs, and there is also a huge purple-red web that stretches over the entire space like a spider's web.

Looking closely, the purple and thunderous lines that formed the big net were also beating slightly, as if there was life, and at the same time, a clear thought suddenly came into Ye Dong's mind: "These lines, in fact, are the same as the meridian acupuncture points on the human body, they are the meridians of the purple flame dragon fire, and they are its life composition!"

One thought, one hundred thoughts!

After figuring out the meaning of these lines in the world realm within the Purple Flame Dragon Fire, naturally Ye Dong also understood the meaning of those lines in the medicinal materials.

"Actually, whether it is a plant, an animal, a human being, or even a flame, in fact, they all have their own life composition, but without spiritual consciousness, they can't feel it, perhaps, they also have their own consciousness and thoughts, but, if you want to perceive it, I'm afraid you need a higher level of spiritual consciousness, yes, just like Lord Brahma said!"

"Adjusting the temperature of the Purple Flame Dragon Fire must be closely related to my spiritual aura, and now that I am fully outputting my spiritual energy, what will happen if I withdraw some spiritual energy?"

After Ye Dong slowly withdrew some aura, he continued to carefully observe the changes in this purple-red world.

The first thing I felt was that the temperature had become lower, and then, those lines that Ye Dong thought were the Purple Flame Dragon Fire Meridians, the beating amplitude became smaller and slower!

"Yes, the speed and frequency of these lines directly affect the temperature of the flame!"

In order to verify the correctness of his idea, Ye Dong withdrew all his aura, and suddenly, he withdrew from the purple-red world, and Yao Shan sat in front of him with an excited face.

Ye Dong smiled awkwardly, he naturally understood what was going on, the Purple Flame Dragon Fire was condensed by his own aura, and when he withdrew all his aura, the natural flame disappeared.

But Yao Shan did it just now, not only to let the flame exist, but also to make it not emit a little temperature, what is going on?

After thinking quietly for a moment, Ye Dong had a flash of inspiration in his mind: "I understand, it is the precise control of the aura, which can make the flame appear, but it does not emit temperature, in fact, it still needs the aura to support, but the amount of aura should be very small!"

Purple Flame Dragon Fire appeared in Ye Dong's hand again, and his spiritual sense quickly probed into it.

Yao Shan, who was sitting on the sidelines and watching, couldn't help but shake his head, his face showed emotion, he knew that Ye Dong had already mastered the method of adjusting the temperature of the flame, because the temperature emitted by the Purple Flame Dragon Fire just now had obviously become lower.

On the second attempt, Ye Dong was much more cautious, no longer withdrawing all the aura at once, but gradually withdrawing it little by little.

Fortunately, when he opened the Shenting Acupoint, Ye Dong's precise control of the aura had been exercised, so it didn't take much time for him to successfully find the degree where the aura could condense into a flame, but the flame would not emit any temperature!

Yao Shan's eyes had already widened, and the emotion on his face had turned into shock, and now he could clearly feel that the flame in Ye Dong's hand had not emitted the slightest temperature, and to do this, it was impossible for a person who was trying to control the temperature of the flame for the first time, without a few months, or even years!

Yao Shan's dust body is Xuanyang Flame, a natural fire attribute, and even if he is a flame dust body, it took him more than two months to do this!

However, Ye Dong has only spent less than half an hour now, and he has already done it!

It must have been a coincidence......

Soon, the temperature of the Purple Flame Dragon Fire in Ye Dong's hand was like a trick, one would be extremely high, and the other would be low to no temperature, and after repeating it several times, Ye Dong opened his eyes, and Yao Shan had to admit that it was not a coincidence!

Of course, Yao Shan didn't know that when Ye Dong opened the Divine Court Acupoint, the degree of control that the aura needed to be controlled was more precise than it was now, so after trying a few times, he would naturally be able to do it easily.

"Elder Yao, I know the truth!"

Yao Shan tried his best to make his face look calm, so as not to let Ye Dong see his surprise, nodded and said, "Well, it's okay, then you can start calcining the medicinal herbs now." ”

"Good!"

Ye Dong happily picked up a violet grass and put it into the purple flame dragon fire.

The violet grass did not burn, and with the gradual increase of Ye Dong's aura, it slowly burned, and almost instantly, it turned into ashes.

Then, the four-leaf flower and the dragon beard root were also successfully burned into ashes by Ye Dong.

Ye Dong looked at Yao Shan, but Yao Shan didn't speak, he reached out and picked up another violet grass, put it into his Xuanyang flame, and said, "Look carefully!"

I saw that this violet grass was quickly ignited by the flames, but it did not turn into ashes, but slowly turned into a puddle of purple liquid, not pure purple, with some other colors in between.

"Burning medicinal herbs is not to burn them to ashes, but to burn them into liquid, at this time, the impurities contained in them will appear, in order to obtain the purest medicinal properties of violet grass, these impurities must be removed, otherwise, the elixir refined after mixing with the liquid of other medicinal materials is likely to have side effects. ”

"The elimination of medicinal materials is also the combination of spiritual consciousness and aura, and you will understand it when you feel it yourself.

Ye Dong nodded, indicating that he understood, in fact, the truth of burning medicinal materials into liquid was still the control of aura, so Ye Dong mastered it after trying it a few times.

Under the observation of the spiritual sense, although the medicinal materials have turned into liquid, there is still a purple world in it, but there will be a few more small particles of different colors, which are naturally impurities.

Find the impurities and use the aura to gently flick them away, which is to remove.

Ye Dong suddenly said in the process of removing impurities: "Elder Yao, is it true that the more abundant the spiritual energy, the less impurities it contains." ”

This opening frightened Yao Shan, the first time he burned the medicinal materials, both the spiritual sense and the spiritual energy were all concentrated, where could he still be distracted to speak, but Ye Dong did it again, and it did not affect the whole process!

"Yes!"

Yao Shan nodded with a wry smile, and at the same time thought to himself, I'm afraid it won't be long before I am not qualified to guide Ye Dong in refining medicine.

Seeing that Ye Dong had mastered the burning medicinal materials, Yao Shan said, "Okay, now prepare three bottles, and then burn the three medicinal materials into liquids separately." ”

Three purple grasses, six four-leaf flowers, and eight dragon beard roots turned into three pools of liquid in Ye Dong's hands, and put them into a bottle ready for the stump.

"In fact, after your spiritual sense can be released, all the steps can be completed in the Ding Furnace, and the next step is the most important step, fusion!"
