Early the next morning, Liu Yun got up early as usual and started a day's morning exercises, getting up early every day to meditate for two hours to cultivate aura and soul perception, which has become Liu Yun's habit in recent years.

Two hours later, the sky grew dark.

Yun'er, are you up? Just as Liu Yun had finished his cultivation, Wang Luo's voice came from outside Liu Yun's house.

got up, Master, said Liu Yun hurriedly stood up, walked quickly to the door, and then opened the door. I saw Wang Luo sitting on the chair next to the table, which was already full of all kinds of fresh medicinal materials, which were obviously picked by Wang Luo early in the morning.

Seeing Liu Yun open the door, Wang Luo motioned for Liu Yun to sit down on the chair next to him.

Liu Yun walked over and sat down beside Wang Luo, and said respectfully, "Master, you got up so early?" ”

Wang Luo gently brushed the snow-white beard on his chin with his right hand, and said with a smile: "I'm old, I can't sleep when I'm old, I don't have anything to do when I get up in the morning, I picked some medicinal herbs, and I just used it when I teach you the art of alchemy today." ”

Looking at the table top, there were about 100 kinds of medicinal materials densely packed together, Liu Yun couldn't help but be very puzzled, what kind of pill is Master going to teach me to refine? How did you get so many medicinal materials? Liu Yun thought in his heart.

Just as Liu Yun was thinking, Wang Luo opened his mouth and asked, "Yun'er, do you know what the most basic steps are in the alchemy technique?"

Liu Yun thought back to the records on the "Dandian", and then said: "Master, the most basic thing in the art of alchemy is to refine the medicinal properties of medicinal materials, which is the so-called chemical medicine. ”

Hearing what Liu Yun said, Wang Luo nodded, and then said: "That's right, the most basic thing in the refining of any pill is to first extract the medicinal properties from the medicinal materials, and the purity of the medicinal properties refining directly affects the quality of the refining of the pills. ”

Saying that, Wang Luo took two medicinal herbs from the table, gave one to Liu Yun, and said, "Yun'er, you and I each refine the same medicinal herb, let's see what the difference is?"

Hearing this, Liu Yun put the medicinal herbs into the palm of his hand, and then activated his aura and began to refine the medicinal properties of the medicinal herbs.

On Wang Luo's side, he took out a medicine tripod, raised the flames, and began to refine.

A few minutes passed, Wang Luo took the lead in refining the medicinal materials, only to see Wang Luo wave his hand, a liquid the size of a mung bean flew out of the medicine pod and floated above Wang Luo's palm, and the rich medicinal fragrance that couldn't tell what taste floated out of the liquid. It is the medicinal properties after refining.

At this time, Liu Yun also happened to finish refining the medicinal materials in his hand, only to see a liquid the size of a soybean grain, suspended above Liu Yun's palm, which also exuded the same medicinal aroma as the liquid in Wang Luo's hand, but it was not as strong as the medicinal fragrance emitted by the liquid in Wang Luo's hand.

Liu Yun first looked at the suspended droplet in his hand, and then looked at the droplet in Wang Luo's hand, which was several times smaller than his own, and obviously felt that the medicinal properties refined by Wang Luo were many times better than those refined by himself! Liu Yun asked Wang Luo: "Master, how can the medicinal properties you have refined are so much stronger than those I have refined?"

Wang Luo brushed his beard with his right hand and said with a smile: "How can you say that the old man has been refining pills for thousands of years, shouldn't he refine some medicinal properties stronger than you?"

Master, I didn't mean that, I was asking you how you did it, I obviously refined all the useful medicinal properties in the medicinal materials! Liu Yun scratched his head and said with some embarrassment.

Are you sure it's all refined?Wang Luo asked with a smile still on his face.

Saying that, Wang Luo took the medicinal materials that Liu Yun had refined into his hands again, and then Wang Luo put the medicinal materials into the medicine tripod again, and rose to the flames, only to see Wang Luo wave his hand, and a woody green breath emanated from Wang Luo's hand, and entered the medicine tripod, and in a moment, Wang Luo's hand waved again, and a very small drop of liquid medicinal properties appeared on Wang Luo's palm, and then Wang Luo's hand shook, and the drop of medicinal properties flew into the droplets above Liu Yun's palm.

Immediately afterwards, Wang Luo waved his palm, and a flame appeared on Wang Luo's palm, and then the flame flew into the droplets on Liu Yun's palm, enveloping the droplets on Liu Yun's palm.

Zizizi...... With a burst of sound, the droplets above Liu Yun's palm began to emit white mist... After a few moments, the droplet became only the size of a mung bean, and after that, Wang Luo withdrew the flames that surrounded it.

After Wang Luo finished doing this, he said to Liu Yun with a smile.

Master, just now when you extracted the medicinal properties of the medicinal herbs, a woody green aura was released, but you used the power of the rules of the wood to refine the remaining medicinal properties of the medicinal herbs? Liu Yun asked with some confusion.

Yes, it's the power of the rules of wood. Wang Luo smiled and nodded.

Also, just now you used the power of the rules of fire to purify my lump of liquid?" Liu Yun asked uncertainly.

Wang Luo then nodded and then said happily: "Yun'er, your understanding is good, what you said is completely correct. To be a teacher is to use the power of the two rules to purify the medicinal properties you have refined again. ”

Wang Luo raised his hand, picked up the water cup on the table, took a sip of tea, and then explained: "All medicinal materials belong to wood attributes, and the medicinal materials you extract only purify the medicinal properties that you can perceive. When you refine all the medicinal properties contained in the medicinal materials, because the medicinal properties contain some water, you need to use fire to evaporate the water contained in them, so as to make the medicinal properties more pure!"

But Master, until now, I haven't comprehended the power of the rules of wood and the rules of fire, Liu Yun said with some embarrassment.

Wang Luo smiled and said, "It's okay, there is no rule of fire, you can catch the ordinary flame first to purify, as for the rule of wood, it is just a waste of a little medicinal property," Wang Luo said, and with a wave of his hand, the drop of liquid suspended on his palm and Liu Yun's droplet into a large wooden barrel that was already full of water.

Then Wang Luo pointed to the pile of medicinal materials on the table and said to Liu Yun: "Yun'er, you first refine all these medicinal materials to extract the medicinal properties, and then purify them over the fire, and put all the medicinal properties into that big wooden barrel. As he spoke, Wang Luo's finger turned to the big wooden barrel that had just been put in the droplets.

Okay, you should be busy first, the teacher is too old to sit still...... Wang Luo stood up, stretched, and walked out of the house.

After Wang Luo walked out of the house, Liu Yun licked his lips and said to himself with a bitter face: "There are so many medicinal materials, when will this be refined......

However, because it was arranged by the master, Liu Yun did not dare to slack off, picked up a medicinal herb on the table, and then held it on the palm of his hand, and after a while, a drop of medicinal liquid was suspended on Liu Yun's palm, Liu Yun raised the flame in the medicine tripod, and then controlled the medicinal droplet in his hand, and slowly moved away beyond the flame.

However... Just as Liu Yungang moved the medicinal droplet onto the flame, it was accompanied by a ... In his lifetime, the change in medicinal properties evaporated as a mist... Left behind some black residue...

Hmm? The sudden change made Liu Yun feel shocked! This...?Liu Yun's brows couldn't help frowning, the temperature of the flame was too high, and the medicinal properties were directly evaporated? Liu Yun muttered to himself.

......

Liu Yun took a medicinal herb again, and after quickly refining the medicinal properties, Liu Yun carefully moved the medicinal droplets around the flame again, but in an instant, most of the medicinal properties evaporated! Fortunately, Liu Yun was prepared and quickly removed the medicinal droplets, but in the remaining medicinal droplets, it was obvious that there were a lot of black medicinal residues mixed with them, and they could no longer be used.

......

After Liu Yun's many attempts, finally after more than a dozen failures, Liu Yun found a way to purify, and successfully purified a drop of medicinal droplets!

I see, as long as the medicinal droplet is a little farther away from the flame, and then the moment of purification, remove the medicinal droplet! Liu Yun said with a little excitement.

However, it is easy to say, but it is a little difficult to do, and after several failures, Liu Yun has completely mastered how to purify.

......

In the blink of an eye, four hours passed, and after Liu Yun threw the last drop of purified medicinal liquid into the big wooden barrel, all the medicinal materials on the table were also refined by Liu Yun!

Hush...... Finally done, Liu Yun let out a sigh of relief, due to the long-term energy and aura consumption, some sweat drops also faintly appeared on Liu Yun's forehead.

Yes, I finished refining the medicinal properties so quickly, faster than I imagined! I don't know when, Wang Luo stood at the door with his hands behind his back and said to Liu Yun with a smile.

Master. Liu Yun bowed to Wang Luo and called respectfully.

No need to be polite, it's just you and me here. Wang Luo waved his hand and said with a smile.

A teacher for one day, a father for life, etiquette is indispensable, Liu Yun still bowed and said respectfully.

Seeing Liu Yun's respect for himself, Wang Luo felt very warm in his heart.

He still looked at Liu Yun with a smile on his face and said, "Okay, Yun'er, you take off your coat now and enter this big wooden barrel, the medicinal properties of this big barrel can't be in vain." ”

...... this?, Liu Yun asked, pointing to the barrel, suspiciously.

Go in, don't ask more, Wang Luo said with a smile.

Liu Yun took off his coat as he said, then left only a pair of shorts, walked into the big wooden barrel and sat down.

When Liu Yun first entered the big wooden barrel, Liu Yun only felt a very refreshing breath poured into hundreds of medicinal waters from the barrel, and entered his body through the pores!
