"Although I haven't practiced, Yunrou has a Dan recipe!" Yun Rou's words suddenly dragged Feng Xue, who had fallen to the bottom, back to heaven.

"What materials are needed? Is it hard to find? Feng Xue's expression was eager, and it looked as if Yun Rou had seen what she had eaten.

"The material is not difficult, it probably takes a stone of yellow sorghum or a hundred catties of dry rice, or food with a similar essence content, the key is that the method of alchemy is more troublesome, and the essence in the pill needs to be extracted, and then condensed into a pure essence pill. Because the refining process has high requirements for flames, there is no way to refine it with mortal fire. You can only use Yang Fire or Dan Fire. Speaking of which, Yun Rou looked at Feng Xue apologetically, "Yun Rou didn't expect to use yang power when she came out this time, so she didn't bring transformation equipment......

"What is Danhuo after talking about it for so long?" Feng Xue asked curiously, at this time, what kind of "Cold Spirit Bone Fire", "Burning Sky Golden Flame" and other things kept appearing in his heart, and he always felt quite tall.

"Danhuo is the flame used for alchemy." Yun Rou replied as a matter of course, "Because alchemy has strict requirements for temperature, all fire is not good, you can only use the true yuan force to adjust the fire, this is Danhuo, in the past, many monks liked to set up Dan furnaces in places where there was earth fire, because the temperature of earth fire is stable, which is suitable for pills that need to be refined for a long time." The Yang Power Fire is the fire power that uses the Yang Power Furnace to convert the Yang Power into the Fire Power, and the temperature of the flame can be controlled by adjusting the output of the Yang Power Furnace, which is much easier to use than the Dan Fire that needs to be distracted and the Earth Fire that cannot adjust the temperature. ”

"Wait...... Let me slow down......" Feng Xue's face darkened, "Are you saying that Danhuo doesn't have any special abilities, just flames that can control the temperature of the flame with the output of True Yuan Force?" ”

"That's right! The ordinary pill medicinal pill fire is enough, and the so-called special flame of the senior brother, even if it is the samadhi true fire with the lowest threshold, can only be used by the great monk who has returned to the void period. Yun Rou didn't mean to be impatient at all, so she explained slowly.

Feng Xue had already understood at this time, and this fire of yang power was a solar induction cooker to put it bluntly!

"Wait a minute!" Feng Xue swooped to the kitchen, found an induction cooker, and showed Yun Rou how to use it—"Do you think this thing is okay?" ”

"It's similar to the use of the Yang Power Furnace, is this using electricity?" Yun Rou's eyes flashed with small stars, "So, it seems that electricity is indeed easier to save than yang power......"

"......" Looking at Yun Rou's scientist-like fanatical eyes, Feng Xue suddenly wondered if this girl was thinking about how to go back and twist the Yang Power Technology Tree on Penglai Island to electric energy.

……

There was nothing to say all night, and early the next morning, he went to the supermarket to buy dozens of bags of rice back and forth, adding up to more than a ton, according to Yunrou, if he refined Bigu Dan, it would take about two years.

Rice, which is enough for ordinary people to eat for more than ten years, can only be used for two years, which makes Feng Xue have a deeper understanding of the consumption of food by cultivators.

Fortunately, he is also a person with storage bags now, otherwise this ton of rice would have to go back and forth at least several times!

"Anyway, alchemy requires a Dan furnace, right? Are there any special material or form requirements? Stacking a ton of rice in the utility room on the balcony, Feng Xue leaned on the sofa and panted, although he said that there was a storage bag, but after taking it out, he still had to work hard!

"It doesn't matter, as long as it's not a magic weapon level Dan furnace, in fact, there is no difference, in the past, the tripod was used because the metallurgical technology was not good, in fact, in the Song Dynasty, Baicaotang was very popular to use iron pot alchemy, and even split out the heyday of the big sect - the Spirit Food Sect, they thought that the pill wasted the taste of the food itself, but instead developed a spirit food with the same effect as the pill, and the taste was also delicious, but it was a pity that Penglai lacked products, and the Spirit Food Sect could only be re-integrated by the Baicaotang...... Yun Rou's words were quite regrettable and said that in fact, the "extinction" time of the Spirit Food Sect is about equal to the time of the establishment of the Penglai Secret Realm, and even among the cultivators, few people know it, and the reason why Yun Rou knows so clearly is only because she likes to eat.

Well, although she eats brown rice in her mouth, it doesn't prevent her from finding some recipes that look delicious, right?

"Okay, it looks like I'm going to emulate the sages, and I don't know what elixir I can make with an induction cooker and a Chinese pot......" Feng Xue complained while taking an iron pot from the kitchen and placing it in the dining room, which was the alchemy location he chose, not for anything else, just because it was empty enough.

In addition, he also carried a fire extinguisher in his hand, which he bought after he knew that he was going to refine the pill, not afraid of 10,000, just in case!

However, after Feng Xue found the equipment, Yun Rou did not start immediately, but stretched out her hands and hugged them in front of her as if she was playing Tai Chi, looking like she was meditating with her eyes closed.

Feng Xue saw Yunrou's posture, worried that there were any taboos, and did not dare to disturb at will, but turned around and knocked on Yunlan's door, this girl began to indulge in martial arts novels after learning to use the computer.

"What's the matter?" Yunlan opened the door, her face was full of "fairy energy", well, this fairy spirit is not the other fairy energy, but the spirit of staying up late to rest the fairy - this girl is afraid that she hasn't slept all night.

Although the cultivator's physical fitness is excellent, this girl is obviously staying up late for the first time, and the sleepy look on her face can't be hidden.

Feng Xue could only smile at this: "It's nothing, I just want to ask Yunrou what is she doing?" ”

"Hmm......" Yun Lan rubbed her slightly baby fat little face, cheered up and looked towards the living room, and her face became strange-"Are you preparing for alchemy?" ”

"yes, you see that?" Feng Xue raised her eyebrows, the iron pot was in the dining room, and the rice was on the balcony, how could Yunlan see it? Could it be that Yun Rou's behavior at this time was a preparation before alchemy?

Yun Lan listened, and did not boast as arrogantly as Feng Xue imagined, but nodded directly: "Well, Yun Rou is condensing the Dan Seed!" ”

"Dan seed?" Feng Xue was stunned by this term, because as a national of the Great Foodie Empire, how could he not know this word?

Of course, some people don't know, but when it comes to tofu, there is no one who doesn't know it, right?

That's right, the source of the birth of tofu is that Liu An, the king of Huainan, cultivated Dan seed (crystal seed) alchemy with soybean milk and inadvertently made it. Feng Xue has always believed that the king of Huainan attained the Tao alone, and the chicken dog ascended to heaven, not because he refined the golden pill, but because he made tofu, so his merits became immortals, and the sun soared.

Literally speaking, the Dan seed is just a crystal seed that increases the crystallization rate, but Yun Rou looks like she is meditating at this time, but it doesn't seem to be so simple......
