Joanna ate it fragrantly, and raised her head when she heard the words: "Alchemy? Is that the kind of ancient Taoist priest who used the furnace to refine the elixir? ”

"Almost, it looks like you don't understand, forget it." Ling Feng smiled bitterly.

"Who says I don't understand?"

Joanna gave him a blank look: "I'm just making sure, why are you asking this?" ”

Ling Feng didn't answer, but asked rhetorically, "Do you really understand?" ”

"Of course, if you don't believe you, let's see if I can answer you!" Joanna pouted.

"Then what does this alchemy method need?" Ling Feng asked.

"Needless to say, alchemy needs furnace ding, the material is divided into different metals, and fuel is also needed, this is more important, different fuel temperatures are also different, and the effect is naturally different!" Joanna said, snapping her fingers.

"Ouch, I really didn't see it, you really know a lot!" Ling Feng was stunned, she didn't expect her to say so much!

Joanna looked proud: "Of course, I'm a family heirloom!" ”

"Oh?"

Hearing her say this, Ling Feng suddenly became interested, and hurriedly asked, "Who in your Qiao family understands this, can I visit it when I have time?" ”

"It's impossible to visit, my grandfather has been dead for ten years!" Joanna said.

"Uh......"

I didn't expect it to be like this, Ling Feng was embarrassed all of a sudden.

However, seeing that Joanna seemed to be fine, and he didn't see any sad expression when he talked about his grandfather's death, he couldn't help but ask curiously: "The old man passed away, did he teach you everything he knew?" ”

Joanna glanced at him: "Can you stop beating around the bush, just say what you want to know!" ”

"Hey, hey."

Ling Feng sneered, and had no choice but to confess: "I want to learn alchemy, what else can it be." ”

"What's weird, don't you have anything to do with this? How can anyone study this now? Joanna asked, puzzled.

"I won't say the reason, anyway, I just want to learn, do you want to teach or not?" Ling Feng asked.

Joanna smiled: "It's not impossible to teach you, but I have a condition!" ”

"Say!"

Ling Feng knew that it was not so easy, and said with a wry smile: "The premise is that I can do it!" ”

"It's very simple, you will definitely be able to do it, my condition is that when you go to the three major families, you have to go to our Qiao family first, or go to my house once if you have nothing to do recently!" Joanna laughed.

Ling Feng was stunned: "That's it?" ”

"yes, that's it, otherwise what do you think?" Joanna asked, tilting her head.

"It's nothing, it's really easy, I promise you!" Ling Feng smiled and nodded.

"Okay, then it's a deal!"

Joanna stretched out her snow-white palm and motioned for Ling Feng to high-five her as an oath.

"It's quite formal, so let's make a decision!"

Ling Feng high-fived her, and then asked, "When did you teach me how to make alchemy?" ”

"Now it's done, wait!"

Joanna smiled slyly, got up and ran out of the house.

Ling Feng was stunned for a moment, then turned his head to look at Li Shiyun and the others: "How do I feel that I have been fooled?" ”

"How so? Anna won't lie to you! Chen Yuhe said.

"But I always have a sense of foreboding!"

Ling Feng scratched his head and said with a wry smile.

After a while, Joanna ran back and threw Ling Feng a thin booklet: "Over to you!" Mission accomplished! ”

"I ......"

Ling Feng was speechless, opened the booklet and looked at it, and found that there were pictures and words in it, but it recorded a lot of things, and looked up at Joanna: "What do you mean?" ”

"It's very detailed, you want to know it's all in it, and I learned it from this! I've got it over to you now! ”

Joanna said with a grin, deliberately accentuating her tone on the handwriting.

"Damn, I'm talking about teaching, not handing, who won't find information, search a lot on the Internet!" Ling Feng said angrily.

"Then you go and search and see if you can find what is recorded on it!"

Joanna pursed her lips, glanced at Ling Feng, and then asked, "You don't plan to go back, do you?" You can be completely self-taught, so why should I teach? ”

“……”

Ling Feng was also speechless, and believed that what she said was true, so he put away the booklet: "Okay, then I'll learn by myself!" ”

"That's right!" Joanna looked smug.

After breakfast, Ling Feng locked himself in the back room, took out the booklet, and studied it carefully.

I don't know if I don't look at it, it turns out that this alchemy is really not a simple matter!

Joanna only said a rough idea before, but if you really want to study it carefully, there are so many details in it, and every part of it is very important.

The material of the furnace is divided into iron, copper, gold, etc., as well as alloys.

The endothermic capacity of different metals is also different, so the effect of alchemy is not the same, and the best is naturally the alloy furnace.

As for the fuel, even if it is ordinary firewood, it is not ranked at all, and the most basic is charcoal, but this charcoal is also particular, divided into fine charcoal and coarse charcoal.

The harder the charcoal made from wood, the better it burns.

However, charcoal is not the only fuel, and there are other heating methods, two of which are listed in the booklet, one is lava and the other is real fire.

Lava is well understood, it is the magma that flows inside a volcano.

And this true fire did not say it explicitly, Ling Feng pondered and pondered, guessing that it might be a samadhi true fire or something, which belonged to the existence of legends.

The materials are already very detailed, and when it comes to the consumables required for alchemy, Ling Feng is even more big!

Instead of throwing things into the furnace and heating it for a period of time, the elixir will come out, each material has a unique processing method, some have to be ground into powder, some have to be heated in advance, and the amount of each is also very complicated.

Ling Feng originally boasted that he was very smart, but after watching it for a while, he felt dizzy and his memory was seriously reduced!

"It's a university question!"

Scratching his head, Ling Feng stretched his arm and let out a sigh!

But despite this, he calmed down and browsed more attentively, trying to remember every detail.

After all, there are already three alchemy materials in his hand, and with the continuous exploration of the third heaven, the alchemy must be carried out.

Time passed quickly, when Ling Feng was still immersed in the booklet, there was a knock on the door, and then Li Fei'er's voice came: "Uncle, it's time to eat, aren't you asleep?" ”

"Who said I was sober!"

Ling Feng got up and opened the door, looked at her and asked, "It's noon?" ”

"And said you didn't sleep, I don't know what time it was!"

Li Fei'er flattened her mouth and said with a look of contempt.

"I'm called forgetting to sleep and eat, what do you know!"

Ling Feng glared at her, stepped forward and put his arm around the little girl's neck, and said happily: "Let's go, go eat!" ”
