Lu Nan didn't care, waved his hand and took another step forward, carefully sniffing the medicinal fragrance in the air.

"You kid can't understand people? Let's get off the ground! Luan Gong stared at Lu Nan and said viciously.

Lu Nan said with a smile: "Two seniors, I have also been studying alchemy recently, and I want to observe it on the side." Rest assured, I will not bother you. ”

"Ridiculous! You are a hairy boy, I am afraid that you can't recognize all the medicinal materials and want to learn alchemy, you don't know how thick the sky is. The woman scoffed.

Luan Gong followed up and said: "That's right, alchemy is quite profound and subtle knowledge, and not all cats and dogs can learn it. ”

Seeing that the situation was not good, Brother Xiang came to Lu Nan's side and said in a low voice: "Brother, let's not disturb Luan Gong and the concubine alchemy, I will take you to visit other places." ”

Lu Nan nodded, turned around and followed Brother Xiang outside.

When he walked to the door, Lu Nan's nose fluttered slightly, turned his head and said: "Senior, the velvet flower can't be roasted slowly at the beginning, otherwise the velvet on the surface will quickly harden into a shell and wrap the petals, and the medicinal properties in the petals will be difficult to volatilize." ”

After speaking, Lu Nan raised his feet and continued to walk out.

"Wait!"

Luan Gong got up and glanced at Lu Nan, frowned, and said, "You said that the edelweiss flower can't be roasted slowly over a constant fire, so what should be done?" ”

Lu Nan stopped and said with a smile: "The stupid way is to scrape off the velvet in advance and then put it in the Dan furnace, but just now there was a smell of burnt velvet from the stove, which shows that you didn't do that." ”

"Sister, take out the edelweiss and replace it with another one." Luan said openly.

"No!" Lu Nan smiled, "You try to increase the flame by three burns, and then adjust the burn level back to its original state at a uniform speed within half a minute." ”

"Nonsense!" Luan Gong suddenly snorted, "The texture of the edrevels, as long as you increase the burning level by one level, it will be baked into medicinal residue in an instant, and if you increase the burning degree by three, it will immediately turn into ashes." ”

Luan Gong glanced at Lu Nan with disdain, and already regarded him as a beginner in his heart, relying on his knowledge of alchemy, so he made a big deal here.

Brother Xiang looked at Lu Nan and asked, "Brother knows alchemy?" ”

"Learned some fur." Lu Nan said with a smile.

Then, he glanced at the Dan furnace again and couldn't help but sigh.

"Stinky boy, what are you sighing for?"

The maid is not young, but her ears are smart, and Lu Nan's soft sigh was also clearly heard by her.

Lu Nan still smiled and said, "At your current speed, when the edelweiss grass breaks open its shell and starts to volatilize the medicinal gas, the medicinal qi of the previous clear water jasper lotus and the herb will be roasted away by at least thirty percent." ”

"So what? These losses are expected. Luan Gong didn't care about it.

"Expected? The two seniors are really rich and capricious. Lu Nan shook his head and smiled.

"This clear water jasper lotus will be neutralized with the medicinal properties of the edelweiss later, if it loses thirty percent of its medicinal properties now, the medicinal qi after neutralization will have thirty percent more fiery properties. After the medicinal gas melts into the ink bead flow berry, the fire property of thirty percent will cancel out the sixty percent of the medicinal property of the ink bead flow berry. In this way, the effect of the elixir will be reduced by at least sixty percent, and this loss is also within your expectations? ”

Luan Gong and the maid listened to Lu Nan's words, and the surprise in their eyes became stronger and stronger.

"How do you know what's in this furnace?" Luan Gong couldn't help but ask.

Lu Nan pointed to his nose and said with a smile: "Smell it." ”

"How is this possible?" Luan Gong didn't believe it.

The woman asked, "I would believe you when you said you could smell the herbs, but the Ink Bead Flowing Berry and the Clear Water Jasper Lotus are both tasteless things, how can you smell them?" ”

"The Qingshui Jasper Lotus itself is not tasteless, but the taste is extremely light, but this smell will be amplified after encountering fire, and it just so happens that my nose is more smart, so I can smell it." Lu Nan said with a smile.

Luan Gong nodded and asked, "What about the Mozhu Flow Berry?" It didn't taste at all. ”

"It's true that the berry itself has no taste, but it changes the aroma of the herbs. Although this change is small, it is not difficult to notice as long as you have the heart to discern. Lu Nan said calmly.

General Luan glanced at Lu Nan suspiciously, and said to the woman: "Increase the burning level by three levels, and then reduce the burning level at a uniform speed within half a minute." ”

The maid frowned and said, "Brother, do you believe him?" ”

"Isn't it just a furnace of medicinal herbs, we can afford to pay for it!" Luan Gong said proudly.

He said it lightly, and Brother Xiang beside Lu Nan was in pain.

These medicinal materials were all purchased by him personally, and the price of each plant started at hundreds of thousands, and the value of the few they said just now exceeded five million.

If this furnace of elixir is destroyed, his five million will be lost.

The woman carefully threw a piece of paste into the fire, and then urged the Liuding Divine Fire Furnace to control the temperature of the fire.

Immediately afterward, the eyes of the two siblings suddenly widened, and the velvet flower did not instantly turn into ashes due to the increase in burning, but quickly melted the hard shell on its surface.

The melted crust flowed down from the petals of the velweiss flower, and the surrounding flames did not burn the petals, but were sucked up by the liquid residue after the crust melted.

When the temperature drops completely, the melted liquid of the hard shell of the velvet is completely detached from the velvet petals, and the velvet petals begin to slowly evaporate under the low temperature baking.

If it is refined according to the original method of Luan Gong and Wu Po, it will take at least half an hour to reach this step. After using Lu Nan's method, the time was directly shortened to one minute, and it was able to reduce the loss of other medicinal gases, which was simply a perfect refining method that killed two birds with one stone.

At this time, the eyes of Luan Gong and Mrs. Lu Nan completely changed, and this hairy boy didn't seem to be as simple as they imagined.

Luan Gong looked at Lu Nan with interest and asked, "Boy, what school did you study from?" ”

Lu Nan said with a smile: "There is no door and no faction, just ponder it at home." ”

"Yourself?" Luan Gong's eyes became disdainful again, and he said coldly, "Are you insulting our brother and sister?" ”

The maid also said with a displeased face: "Learning to lie to elevate yourself at a young age is simply arrogant and immoral!" ”

"This mother-in-law, you can say that I am arrogant, but it is too much to say that I am not virtuous, right?" There was a chill on Lu Nan's face.

These two people have been relying on the old and selling the old from beginning to end, and their words are prickly, and they have always greeted each other with a smile for the sake of their age.

Now that I have helped them solve a problem, they still treat it with this attitude, do you really think that Lao Tzu is a soft persimmon that can be broken when pinched!

Seeing the displeasure on Lu Nan's face, the maid didn't care at all, but said with a leisurely face.

"Young people should guard against arrogance and rashness, and when you reach our age, you can also reprimand people of your age."
