Liu Yu had already noticed the strange gazes cast by these people, he put down the dishes and chopsticks, and said: "Qiantou, don't leave after dinner for a while, I will tell you the formula and refining method of the Red Flame Elixir, and then I will trouble everyone to work hard tonight, work overtime, and refine more Red Flame Elixir at night." ”

Qian Feixuan and the others were stunned at first when they heard this, and then they couldn't believe it.

After all, the formula and refining method of a new potion are extremely precious things, and usually after a pharmacist develops a new potion, it will be regarded as his own special skill, and will not be easily taught to others.

And Liu Yu didn't mention any conditions, so he directly said that he would teach them the formula and refining method.

Several people looked at each other for a while, and after confirming that Liu Yu was not joking, several people were immediately ecstatic.

As for Liu Yu's talk about letting a few people work overtime tonight, in the face of learning a new potion formula and refining method, working overtime is a......

……

In the evening, Liu Yu personally demonstrated the whole process of refining the red flame elixir to Qian Feixuan and the five people in the laboratory on the second floor of the small building store.

Qian Feixuan and the others looked at the potion in the flask, which gradually changed from a liquid state to a state of flames, and their eyes widened in shock, and Wu Bing and Zheng Shanshan exclaimed in surprise.

Until Liu Yu finished refining the potion, Qian Feixuan and the others were still in shock and couldn't extricate themselves.

After a long time, Qian Feixuan was the first to wake up from that slightly trance state, he took off the flask containing the potion on the iron frame, looked at the flask in a state of flame burning, showed an obsessive look, and sighed again and again: "It's incredible, it's incredible!" ”

After sighing, Qian Feixuan muttered to himself at the Red Flame Elixir again: "After seeing this Red Flame Elixir, I realized that the original Elixir is so broad and profound, and my self-proclaimed identity as a leader in the pharmaceutical industry is nothing in front of such a broad and profound pharmacy academic. ”

Liu Yu didn't pick up, he knew that this was Qian Feixuan expressing his inner emotions.

Not only Qian Feixuan, but also Wu Bing, Qiu Min, Zheng Shanshan and Zhao Cheng, the impact of the Red Flame Elixir when they saw it was no less than Qian Feixuan. The refining method of the Red Flame Elixir, including the process of transforming it from a liquid into a flame, almost all of this subverted their previous perception of the potion!

The huge impact force made it difficult for several people to come back to their senses for a long time.

In the alchemy laboratory, there was silence for more than a quarter of an hour, and Qian Feixuan and the others were able to recover their strength, and immediately after, the eyes of several people began to heat up. The Red Flame Elixir, or the type of Combat Elixir, can be regarded as opening a new door for them in the Elixir Field.

Continuing along this door, perhaps they will have access to a new level of potion knowledge that no other apothecary on the entire planet of Kalan has been exposed to.

And all of this was brought to them by Liu Yu, and there was no moment when they were so convinced that if they followed Liu Yu on the potion, they might come into contact with the true meaning of the potion.

Although they didn't know what the true meaning of the potion was, at this moment they had a blind confidence in Liu Yu, the person who had been creating miracles.

……

Of course, Liu Yu didn't know the mental activities of Qian Feixuan and the others at this time, he asked Qian Feixuan and the others to start trying to refine the Red Flame Elixir, and then gave some guidance in the process of refining the few people, until Qian Feixuan and the others were already able to refine the Red Flame Elixir independently, he left this potion laboratory with confidence.

Since he was going to start bartering the sale of Red Flame Elixir tomorrow, he had other things to do tonight.

For example, formulating barter rules and formulating rules is a very cumbersome work, which involves many aspects of conversion work.

But fortunately, Liu Yu has a brain chip in his head, and with the computing speed of the brain chip, in just a few dozen minutes, he drew up the rules of bartering one by one.

One kilogram of the best energy stone can be exchanged for ten red flame elixirs, one kilogram of high-grade energy stones can be exchanged for one red flame potion, ten kilograms of medium-grade energy stones can be exchanged for one red flame potion, and one hundred kilograms of low-grade energy stones can be exchanged for one red flame potion.

As for how to judge the grade of the power stone, Liu Yu has already planned this. He planned to leave the matter of judging the grade of the power stone to Mu Yue and the four robot leaders, after all, they were all intelligent beings, and they were very clear about how to grade the power stones.

In addition to the energy stones, which can be exchanged for Red Flame Elixir, the raw materials for refining Red Flame Elixir can also be exchanged for Red Flame Elixir, but the exchange ratio is much lower than that of energy stones, and it is equivalent to refining ten times the amount of Red Flame Elixir raw materials in order to exchange for a Red Flame Elixir.

……

The next day, before the opening of the Pharmacy Villa, Ye Qing took the rules for exchanging the Red Flame Elixir prepared by Liu Yu and divided it into two parts, one was posted on the side of the shelf selling the Red Flame Elixir in the small building store, and the other was posted by him on the billboard at the entrance of the Pharmacy Villa.

When Ye Qing went out to post the exchange rules, he suddenly found that there were already many people waiting at the door of the Pharmacy Villa at this time, obviously these people were waiting for the Pharmacy Villa to open, so they could rush in to buy the potion as soon as possible.

When those people saw Ye Qing coming out of the Pharmacy Villa, they immediately came over eagerly and asked, "Hey, little store manager, is there a Red Flame Potion for sale in the Pharmacy Villa today?" ”

Ye Qing said with a smile while posting the exchange rules: "Yes, but Liu Yu, the owner of our Potion Villa, said that the purchase method of Red Flame Elixir does not accept the purchase of card blue coins, only barter. ”

"Huh? Barter? "Many of these people queuing at the door didn't know what happened in the Potion Villa yesterday, and they didn't know that the Red Flame Potion only accepted barter. At this moment, when they first heard that the Red Flame Elixir had to be purchased in the form of barter, these people immediately became a little anxious......

I only heard one person ask a little anxiously: "I only accept barter, how is this good, I only brought the card blue coin today, and I didn't bring anything else!" ”

With this voice, many people said that they only had card blue coins on their bodies, and asked Ye Qing if he could be accommodating.

Ye Qing shook his head and said, "I'm sorry everyone, this is the purchase rules set by our owner, and I have no right to change them." Fortunately, it's still early, so you might as well go back and prepare for the exchange after reading the barter rules, and then come over to buy the Red Flame Elixir. ”

When Ye Qing's voice fell, another person asked, "What do you need to exchange for the Red Flame Elixir?" ”

Ye Qing patiently replied: "Do you see the billboard I am posting, regarding the exchange rules of the Red Flame Elixir, this billboard is clearly written." ”
