When Wang Kan came to the Heart Cultivation Palace, Chu Mo had already arrived.

Seeing that the two of them had arrived, Che Dan Zhenren motioned for the two to lean over and prepare to start teaching Dan Dao.

With a wave of his hand, Che Dan Zhenren summoned a Ding Dan furnace from the storage treasure.

The Ding Dan furnace summoned by Che Dan Zhenren was dark all over, and when seen from a distance, it looked like a hollow iron lump.

Wang Kan circled around the Dan furnace a few times, but he didn't see anything why.

Chu Mo also leaned over, looking left and right.

Master Che Dan Zhenren looked at the curious eyes of the two apprentices, walked down, came to the side of the Dan furnace, and with a wave of his hand, a flame rose at the bottom of the Dan furnace.

After the entire Dan furnace was injected with flames, it suddenly became radiant, and there was no longer the ordinary feeling it had before.

"This Dan furnace, called the Falling Heaven Furnace, is made of Falling Star Dark Iron. The teacher has already ordered two Dan furnaces for you, and they will be delivered when they are finished. Now, I'll show you a little bit of alchemy. ”

Che Dan Zhenren explained to the two apprentices while refining the pill.

"The so-called alchemy is nothing more than two methods, that is, essence and fusion, I will show you the essence first. ”

With another wave of his hand, a Yunmei leopard bone that Wang Kan had handled before flew into the furnace.

A pale cyan soft true qi slowly poured into the Falling Heaven Furnace along Che Dan Zhenren's fingertips.

After the true qi was injected, the flames in the Falling Heaven Furnace suddenly rose a few points, and the scorching waves of qi rushed through the Falling Heaven Furnace.

The Falling Heaven Furnace was hollow, and you could directly see the bones of the cloud-eyed leopard curling up under the scorching of the Dan fire, making a slight crackling sound.

"Chu Mo, you should have seen alchemy before, what do you think. ”

Chu Mo obediently took a few steps forward, and Zhou Sheng's true qi fluctuated, resolving the heat wave that was blowing in his face.

"I've seen the elders of the clan worship alchemy at home, but most of them use the fire spirit true yuan to generate flames, or directly use the Yuan Sheng Dan fire between heaven and earth to make alchemy. ”

Che Dan Zhenren heard Chu Mo's answer and nodded with satisfaction.

"Very good, the immortal sects in the world often think that only the fire spirit root is the most suitable for alchemy, but this is not the case. After cultivating the Dan Dao for many years, he finally came to the conclusion that the Wood Spirit Root and the Wood Spirit True Yuan were the most suitable for alchemy. ”

Chu Mo suddenly felt very puzzled, this statement undoubtedly subverted her cognition.

Wang Kan listened indifferently, anyway, he didn't know anything, what the master said, it was what it was.

"Why do you say that the best spiritual root for a cultivator to refine the pill is the wood spirit root? Because, in addition to some exclusive exercises, the more extreme the cultivation of the fire spirit root, the more domineering the power of the flame becomes, which actually does not help alchemy. ”

"And those exercises that are exclusive to alchemy are often very difficult to practice, and even if they are practiced, they can only be used for the way of alchemy, and they cannot kill the enemy in battle. ”

"The wood spirit root is different, the wood is mild and can be retracted freely. When alchemy, just start a fire, you can mobilize the Wood Spirit True Yuan in your body to supply the flames, but it is easier to control than the Wood Spirit True Yuan. Both of you are good wood spirit roots. Wang Kan's Wood and Water Twin Spirit Roots are the same as those of the teacher, and Chu Mo's Wood Fire Twin Spirit Roots are even better. ”

Wang Kan listened to his master's explanation, combined with the theory of the five elements of yin and yang that he had learned in the past, and he had a general understanding.

The five elements of yin and yang are mutually reinforcing, wood is fire, and fire is gold.

Therefore, the exercises practiced with the wood spirit root are actually more suitable for alchemy.

In fact, Wang Kan, who has a foundation in modern science, is easier to understand.

The Wood Spirit True Yuan is like the oxygen supplied to the flame burning, and controlling the amount of oxygen is naturally much more convenient than directly controlling the flame.

Wang Kan couldn't help but feel extremely mysterious, could he still embark on the road of scientific cultivation in the future?

"Okay, let me ask you a second question, where is the hottest flame in this Dan furnace?"

Che Dan looked back at his two disciples and asked.

"Is it the center of the flames?"

"It's the outer flame. ”

Both responses rang out almost simultaneously.

The former is Chu Mo, who is looking at Wang Kan with big eyes and confusion at the moment.

And the latter is naturally Wang Kan, who confidently said this answer.

"Wang Kan is right, it's the outer flame, it's optimistic. ”

Che Dan Zhenren put his fingers together, pointing to the cloud-eyed leopard bone that had been burned into a ball of black bone powder in the Dan furnace.

Under the control of Che Dan Zhenren, the black bone meal gradually floated upwards and reached the top of the jumping flame in the Dan furnace.

"Poof!"

With a soft sound, the black bone meal ball turned into a small white liquid in an instant.

"The inner flame is refined at high temperature, and the outer flame removes impurities, which is the basic method of extraction. ”

Wang Kan hurriedly took what Master Che Dan said in his heart.

The white liquid in the Dan furnace was gradually condensed under the scorching heat of the high-temperature furnace fire, becoming smaller and smaller, until it condensed into a pearl-like ball, Che Dan Zhenren's right finger technique changed, and the condensed ball flew out and fell into the small jade bottle prepared in advance.

"This is the leopard bone essence completed by the extract, which is one of the common materials for alchemy. ”

Che Dan said to Wang Kan and the others, and then looked at Chu Mo.

"Chumo, you try it first. ”

The little girl nodded, walked to the front of the Dan furnace, and began to refine the cloud eyebrow leopard bone according to the instructions of Che Dan Zhenren.

"How is it?Wang Kan, what do you think of this way of alchemy?"

Che Dan Zhenren instructed Chu Mo to operate and asked questions at the same time, in fact, he asked casually, and he didn't expect Wang Kan to really say anything.

Wang Kan was stunned for a moment, obviously not expecting the master to ask himself this.

In fact, Wang Kan thought that his master was here to perform alchemy for the two of them, but he didn't expect that he would directly start to let Chu Mo personally practice the essence, let alone ask questions.

What are your thoughts?

Wang Kan thought about it in his heart for a while, and said seriously:

"Back to Master, I think alchemy is quite similar to cooking. ”

"Boom!"

There was a roar from the Falling Heaven Furnace made of Falling Star Darkiron.

Chu Mo looked at his senior brother and master pitifully, and there seemed to be tears rolling in his eyes.

And Che Dan looked at his big apprentice with a complicated expression, not knowing what to say.

"Isn't that right? Essence, just like when cooking, it is usually stir-fried over high heat to bring out the flavor of various ingredients. ”

"Then it's a fusion, it's like scrambled eggs with tomatoes, that is, the tomatoes are stir-fried to get juice, then the eggs are scrambled until fragrant, and finally mixed together, huh...... It's crazy to think about it. ”

And according to this statement, if you want to make the dish delicious, spices are naturally indispensable, just like when refining the pill, in order to stabilize the pill, many other medicinal materials are often added to reconcile. ”

Wang Kan didn't seem to care at all about what had just happened, and explained to himself.

After listening to Wang Kan's remarks, Che Dan Zhenren fell into deep thought.

Chu Mo, on the other hand, completely forgot the fact that he had accidentally fried the furnace just now, and asked with big eyes:

"Senior brother...... I know the egg, but what is a tomato?"

Wang Kan then remembered that there were no tomatoes in this world, so he explained:

"Oh, a fruit, sour, sweet. ”

"If you think about it carefully, there is some truth in your statement, and sure enough, the avenues under the world are all connected, and this statement will be discussed with those old horsemen next time the Wuzhou Dan Meeting. ”

Wang Kan naturally didn't know that his alchemy today was very similar to cooking, and it would affect the entire alchemy world and even the cultivation world in the future.
