"You refine the Heart Extraction Grass once and show it to me. www.biquge.info"Seeing that all the medicinal herbs have been delivered, Venerable Wind said.

"Yes. Li Yun listened respectfully and said. After speaking, he opened the lid of the furnace and put the herb into the furnace, and after covering the lid. A wisp of red flame suddenly rose, and the excellent soul power also drilled into it instantly, and then the temperature immediately increased, and the drops of green liquid on the body of the Extraction Heart Grass in the Dan Furnace began to flow out, seeing that the liquid had begun to flow out, Li Yun is soul power moved, wrapped all the Dan liquid, and then raised the temperature a little, and suddenly, the Essence Heart Grass in the Dan Furnace began to melt at an accelerated rate. And after this melting lasted for about half an hour, when the last Essence Grass turned into green pill liquid, Li Yun's face also showed a smile.

Retracting the flames, withdrawing the soul, and when the lid of the furnace was opened, a furnace of green pill liquid appeared in the field of vision of the two of them. And after seeing the same color and evenly concentrated Dan liquid, Venerable Feng also nodded. The whole process was smooth and smooth, and there were not many mistakes like at the beginning, after so many refining exercises of the Extraction Heart Grass, Li Yun had already begun to have a little feeling for the refining of medicinal materials.

"Well, that's right, the next thing I'm going to teach you is the most basic first-level pill, called Zhuji Dan, which is used by the lowest level of qi, and has the effect of stabilizing the vein and laying the foundation. I won't demonstrate, some things still need to be understood and explored by yourself. Venerable Wind said.

"Yes, disciple knows. Then the disciple began to begin. Li Yun said.

After speaking, the terrifying flames directly incinerated the Dan liquid in the Dan furnace, and then turned his gaze to the mountain of medicinal materials next to him. And this mountain of medicinal herbs is divided into three kinds, one of which is a green grass, there is a faint mist attached to the grass, and if you feel it carefully, it is actually vitality, although this vitality is very thin, but it is real.

And next to this little grass, a black flower lies there quietly, yes, it is a black flower, the whole flower, including the rhizome of the flower, is black, it looks extremely weird. Next to this strange flower is a huge tree root-like thing, but this so-called "tree root" is actually purple, and there is a faint energy coming out of the "tree root", which is similar to the small grass at the beginning.

"This is the Vitality Grass, the Night Flower and the Purple Whisker Root? It actually contains a little vitality and energy. Looking at these three different medicinal materials, Li Yun was surprised.

"This is only the most basic and cheapest medicinal material, so the energy contained in it is very weak, but there are some more special medicinal materials on the contrary, the terrifying energy contained in its body is not necessarily dared to touch even me, you will know later." Let's go. Venerable Wind said when he heard this.

"Yes. Li Yun nodded, then put the three materials in and covered the furnace lid. The red flame appeared instantly, and the temperature in the Dan furnace also rose several degrees in an instant. At the same time, Li Yun's outstanding soul power also drilled into it. Li Yun didn't know anything about the refining temperature of these three medicinal materials, so he needed to rely on his soul power to determine the most suitable temperature.

As the temperature increased, the situation in the Dan furnace began to change. And the first to change is the vitality grass, almost the moment the temperature rises, the vitality grass begins to melt, and the night flower is the same, but compared to the melting of the night flower, it is a little slow, but at least the flowers of the night flower have begun to gradually decrease, and a purple liquid on the night flower has also begun to drip out.

And after this change lasted for three hours, the Yuan Qi Grass and the Night Flower all turned into pill liquid, but what made Li Yun's heart sink was that there was no change in the purple beard root at all, and under the perception of Li Yun's soul, the energy in the purple beard root was still stored in it, and the appearance of the purple beard root was not damaged at all.

"Is this purple whisker root so difficult to refine?" Li Yun was also surprised to see the intact purple whisker root. Immediately, the red flame moved, instantly raising the temperature a lot, but what annoyed Li Yun was that the purple whisker root still didn't react.

"I don't believe I can't refine you. Li Yun said angrily in his heart when he saw it. After speaking, the temperature of the red flame rose again, and a terrifying temperature was instantly transmitted into the Dan furnace, and with the appearance of this terrifying temperature, the stubborn purple whisker root finally reacted. Seeing that the purple beard root had a reaction, Li Yun also gave a sigh of relief and smiled. But then Li Yun's face changed, and a muffled sound came from the Dan furnace.

"Let's refine again. At this time, Venerable Feng said lightly when he saw it.

When Li Yun heard this, he withdrew the flame and opened the Dan furnace. A burnt smell came out of it, a purple-green liquid attached to the bottom of the Dan furnace, and it was from this liquid that the burnt smell came out.

"Is the temperature too high? However, if the temperature does not increase to that point, it will not be able to refine that purple whisker root at all. Seeing the scene inside the Dan furnace, Li Yun also knew where his problem was, but if he didn't raise the temperature, the purple whisker root would not be able to be refined at all.

"Try again. Dumping the waste liquid in the Dan furnace, Li Yun decided to start over.

As with the first procedure, Li Yun was familiar with putting the three medicinal herbs into it, and then slowly raised the temperature, just like at the beginning, the first to refine were the Yuan Qi Grass and the Night Flower, but the purple whisker root still fell intact in the corner of the Dan Furnace. This time, Li Yun was much more careful, wrapping his soul in the Yuan Qi Grass and the pill liquid after the night flower refining, and then raising the temperature of the flame.

Suddenly, under the high temperature, the purple whisker root also moved, but Li Yun frowned at this time, because he found that even if he had his own soul wrapped in the pill liquid, the temperature inside the pill liquid began to gradually rise, according to this trend, before the purple whisker root was completely refined, this pill liquid would have to become waste liquid because of the high temperature.

Rumble...... Retracting the flames, Li Yun did not continue refining, but opened the Dan furnace and looked at the purple whisker root inside the Dan furnace and fell into deep thought.

At this time, Venerable Feng didn't speak when he saw it, some things are actually very simple, it depends on whether you can think of it.

And after Li Yun's contemplation lasted for about half a day, he finally made a move.

Just like at the beginning, Li Yun opened the Dan furnace and put the medicinal materials into it, but at this time, Li Yun only put the purple beard root as a medicinal material into it, and the Yuan Qi Grass and Night Flower were not in a hurry to put it into the Dan furnace. After putting the purple whisker root inside, red flames instantly appeared, and they burst out at the most terrifying temperature at the beginning. Suddenly, the purple fibrous roots in the Dan furnace also began to melt gradually, and a crystal clear liquid fell off from the purple fibrous roots.

"Since the temperature you need is high, then I'll refine you first. I just came up with such a simple truth, and it's really a bit stupid. Looking at the purple whisker root that had begun to melt, Li Yun smiled and said.

And the Venerable Wind next to him also nodded when he saw it, that's right, the easiest way is to change the order. In this way, you can be sure that the Dan liquid will not become a waste liquid due to the high temperature. Of course, when your alchemy level increases in the future, and the flame temperature control increases, you will naturally not need to use this method.

"Refining is no problem, but the real difficulty has just begun. Seeing the Dan liquid slowly appearing in the Dan Furnace, Venerable Feng muttered.
