"Yeah." Rhett made a gesture and immediately activated the device, mentally triggering the spiritual imprint left by Heisenberg in the pigeon whistle, which was equivalent to a pat.

There was no crackling sound of electricity, nor any other chaotic sounds. Almost in the next second, Heisenberg's strange and unpleasant voice came from the pigeon whistle in Leiter's hand:

"Dagurala? Are you crazy? Didn't I tell you in advance not to use the pigeon whistle to contact me if nothing is wrong? You should know that no matter who initiates the contact, the consumption of both parties during the communication period is the same! In the barracks... Eh? Not in the barracks? Where did you go? If you have any questions, come to the alchemy workshop. I don't have many high-level wind magic crystals left. I don't have time to waste with you..."

A series of voices revealed a strong sense of impatience. Lei curled his lips and heard that the other party was about to hang up the pigeon whistle, so he quickly said: "Don't hang up so quickly, there is something important!"

"What's the matter? I'll give you five seconds!" Heisenberg's casual voice came.

"I came to the old ruins and seemed to have found some memories of the past. If I go back now, I'm afraid I will lose my form and miss some precious memories..."

"Oh, damn, why didn't you tell me about this earlier? The thing I have the most is wind magic crystals! By the way, what do you remember? Please tell me quickly!" A cry of surprise suddenly came from the carrier pigeon whistle, and then a hint of hope was revealed.

Rhett rolled his eyes, smiled at Manu, and saw what was written on the sign Manu picked up, and said:

"I remember... the alchemical patterns I told you at the beginning seem to need to be combined with specific alchemical materials to play a real role. If you simply draw them, you may not achieve the desired effect, or even go in the opposite direction."

The sound coming from the pigeon whistle was very clear. First there was the sound of the pen tip rubbing against the paper quickly, followed by Heisenberg's excited response:

"What you said is also what I have been thinking about these days. It seems that you have really recalled some useful information. Where are you now? I want to go find you!"

Lei Te coughed twice and said, "Forget it. You don't need to come in person. The important thing is that I am in a very strange state now. If I am disturbed a little, I may not be able to recall more useful information..."

"Well...Okay, then tell me quickly, which materials are more suitable for these patterns?" Heisenberg asked helplessly but eagerly from the other end of the pigeon whistle.

"Well, with my limited knowledge of alchemy, I can't tell what kind of material it is, but I'm sure that the material doesn't seem to be obtained naturally, but rather some kind of artificially synthesized material." Rhett looked at the content provided by Manu and replied quickly.

"Synthetic materials?" Heisenberg's voice sounded doubtful, but also somewhat enlightened. "I see... By the way, do you still remember the clearer alchemical patterns? If you do, please draw them locally and bring them to me. I will give you generous rewards."

Rhett glanced at Manu, looked at the new content on the cardboard, coughed twice and said, "Ahem, now that you mention it, I can indeed recall some clearer memories, and can also roughly restore the general outline of the original equipment, not just limited to the plane. But..."

"That's great!" Heisenberg focused on the first half, and when he heard that he could even restore the outline, he cheered! Then he recalled and asked, "Just what?"

"I have some questions about alchemy and would like to ask you!" Rhett said slowly.

"Are you also learning alchemy? Haha, then you have come to the right person to ask. But you may not know that alchemy is a vast and complex subject. It is impossible to explain it to you clearly in a short time. Come to my laboratory and I will allow you to sit in." Heisenberg was still obsessed with the alchemy patterns and said in a persuasive manner.

But the only response he got was a lazy yawn...

Heisenberg was frustrated in the laboratory and said helplessly: "Well, if you don't understand anything, you can ask me now. Although you are not my student, you can understand this as an equivalent exchange!"

Leiter cleared his throat, "Then I'll tell you."

"Too long-winded, hurry up!"

"Okay, please tell me about the production process of the pigeon whistle, the raw materials required, and which alchemical patterns are needed!" Rhett said straightforwardly.

“.”

There was a rare moment of silence on the other end of the pigeon whistle, and suddenly Heisenberg's somewhat gloomy voice came:

"Dagula, didn't I say that the making of the pigeon whistle was the greatest achievement of my alchemy? You should remember this clearly. Why are you still asking about this question now? What exactly does it mean?"

Leiter glanced at Manu, who gave him a calm look, and then responded calmly:

"Since you mentioned equivalent exchange just now, I think we should also respect this principle. Regarding this alchemical pattern I discovered, there is one important piece of information I forgot to tell you. Its effect is closely related to healing, and it seems to have the effect of bringing the dead back to life."

"Of course, I'm not sure if it's correct, but I have reproduced the alchemical patterns almost completely and accurately on the original instrument. How much do you think this great alchemical achievement is worth?"

There was silence again on the other end of the pigeon whistle, but Leiter could faintly hear heavy breathing. A few seconds later, Heisenberg's fanatical voice came: "You just said it has healing effects? It actually has healing effects!"

As if to confirm his own analysis and judgment once again, Heisenberg no longer doubted the truth of Leiter's words, but said firmly: "As long as you bring the things back and let me verify their authenticity, I will tell you in detail how to make the pigeon whistle!"

Although Heisenberg had an eccentric personality, his pursuit of alchemy was beyond reproach. However, in the eyes of outsiders, influenced by his style of doing things, he exuded a sense of weirdness from the inside out, making people ignore his dedication to alchemy.

This time, it was obvious that Heisenberg was determined to get the alchemical results that he guessed were epoch-making, even if it meant paying a huge price!

He believed in his own judgment and knew that he would never make a mistake. The value of this alchemical pattern was inestimable.

Lei Te took out a high-level wind magic crystal from his arms. Seeing that the energy in the pigeon whistle was about to run out, he planned to make a seamless connection without interrupting the conversation. He first said: "Don't worry, I will definitely bring the things over, but you are the only sanctuary in the military camp at this time, and my safety cannot be guaranteed. So you should tell me the production principle of the pigeon whistle first, which is more in line with the fair principle of the transaction!"

"Oh no, what if you run away?" Heisenberg retorted sharply.

"Aren't you afraid that I will go out to look for you? The communication range of the pigeon whistle is only ten thousand miles at most. I just need to search along the radius and it won't be difficult to find you."

"Then you will never see the great results of alchemy, and you will be wanted by our kingdom!" Rhett fought back strongly.

There was a sudden silence on the other end of the pigeon whistle.

After a full half minute, Heisenberg suddenly laughed heartily: "Hahaha, what are you talking about? I was just joking with you, but you took it seriously! With your intelligence, you are destined not to have a great soul, let alone become a top alchemist!"

Leiter smiled but continued to listen, and Heisenberg quickly said, "Listen carefully, here is the detailed production process of the pigeon whistle: a wind-type holy bloodline monster, at least a heart of a high-level life form, and the bones are melted into essence. If you want to refine a top-notch pigeon whistle, you need materials from a specific wind-type holy bloodline monster - the Wind-Splitting Sky Beast. In addition, you also need purified wind magic crystals and elemental minerals - windless ore, flowing water ore..."

The narration took five minutes, even though Heisenberg spoke faster and without pausing.

Fortunately, the pronunciation was clear, and Rhett and Manu had excellent memory, so they remembered it firmly after just one hearing.

Of course, to be on the safe side, Manu still wrote down everything in a notebook with large pages.

Gulp, gulp, the sound of drinking water came from the other end of the pigeon whistle. Heisenberg said in a shrill voice: "Well, Dagula, I have done what I should do. When will you fulfill your promise?"

Ding! The pigeon whistle suddenly went off.

Heisenberg, standing in the alchemy workshop, narrowed his pupils, was stunned for a moment, and a look of disbelief flashed in his eyes.

He immediately flew into a rage, slapped the table, and yelled, "How dare this Dagula play tricks on me!"

Mingge in the room felt the room shaking and his shoulders shrank. He couldn't help but wonder what the Great Master had done to make Heisenberg like this?

A few seconds later, just as Heisenberg was about to slam the door and leave to look for Rhett, the carrier pigeon whistle vibrated again.

He was moved, and after the call was connected, Lei Te's voice came from the pigeon whistle: "Sorry, the pigeon whistle ran out of power just now... Oh no, it ran out of energy. I forgot to replace the magic crystal in time. Speaking of which, the consumption of this thing is really terrifying. Even if ordinary people can get this thing, they don't have so many resources to use it."

In the wilderness, Rhett looked at a patch of green powder on the ground. It was the wind magic crystal in the pigeon whistle whose energy had been exhausted. He didn't know why the magic crystal exhausted by the device would automatically turn into powder?

Even if the energy of an ordinary magic crystal is exhausted, only the color and hardness will change.

He sighed twice. In just a short while, he had already used up seven magic crystals. If he had not been the deputy commander, where would he get so many resources to squander? Heisenberg's disdainful ridicule came from the other end of the pigeon whistle, "You can return it to me if you can't afford it. I regret giving you the pigeon whistle now..."

Leiter smiled and put the pigeon whistle to the corner of his mouth, "Haha, no, you won't regret it! Don't worry, in order to respect equal exchange, I won't let you suffer any loss. I have some other interesting alchemical knowledge here..."

"Hmph, apart from that alchemical pattern, what else can compare to it? You'd better come back as soon as possible, I'll be waiting for you at the glacial defense line. That's it, I don't have many magic crystals here..." Heisenberg replied listlessly. His mind was now full of the complete and detailed alchemical pattern that Rhett had described, and he had no interest in anything else.

"Really? That's a pity. I still have some high-quality potion formulas here, which are very different from the current alchemical potion system. I was planning to give them to you for free as compensation for the things you gave me a few days ago. Since you are not interested, forget it..." Rhett deliberately sighed and pretended to hang up the pigeon whistle!

"Wait!! I'll ask Mingge to find someone to exchange for some magic crystals!"

The sharp sound almost pierced his eardrums. Rhett took a breath, stared at the pigeon whistle, and resisted the urge to scold the other party.

The next moment, Heisenberg's urgent roar came again from the other end of the pigeon whistle.

In the alchemy workshop, Mingge turned around blankly and gave Heisenberg an inquiring look, as if to say, do you need me to go out and exchange the magic crystals now?

Heisenberg made a gesture to shut up, took out a bag from his space ring, and with a flick of his finger, dozens of high-level wind magic crystals fell out.

Mingge was stunned for a moment, turned around, pouted, and muttered to himself: "What a face-saving old man..."

"Well, okay. I was just flipping through it and accidentally found a batch of wind magic crystals. Let's continue with the alchemical potion formula you just mentioned..." Since it was a remote connection, Heisenberg was not afraid of Rhett seeing it, and said with a slightly red face.

Rhett also gave Heisenberg face by not exposing him, but tried hard to recall the alchemical potions of the current era that he had learned about in the past two days.

Compared with later generations, the alchemical potions of the two eras have their own advantages and disadvantages. Some potions have been passed down from the current era to later generations, but more potions are actually unrecognizable.

Compared with the effects, alchemical potions in later generations are generally better developed - with less consumables on average and a relatively higher success rate.

"Listen carefully, there are Nirvana potion, fluorescent potion, septicaemia potion..."

After Leiter told Heisenberg the names of the potions one by one and the formulas and refining processes, Heisenberg first hung up the pigeon whistle and quickly experimented in his own laboratory. Then he contacted Leiter again and exclaimed in disbelief: "Oh my God, healing potions can be refined like this? It's a completely different idea from the current world, and the effect is slightly better! And these poisons, although they don't seem to be of high grade, are also remarkable. And this fighting spirit potion, the cultivation speed has also increased slightly..."

Leiter could guess Heisenberg's surprise from his tone, and asked with a smile: "How about this gift? Can it make up for your loss..."
