"Shopkeeper Chen, I can assure you that I only use this prescription for my own personal use and will never use it for commercial purposes!"
Shopkeeper Chen of the drugstore, who originally didn't want to agree, finally agreed under Xu Yi's sincere assurance and the 'sincere' look of the guard with a knife behind him.
He happily took out the prescription.
However, before handing the prescription to Xu Yi, shopkeeper Chen couldn't help but ask.
"Master Xu, are you sure this is just for your own use?"
"Of course, Shopkeeper Chen, you should know best what this prescription is like. If it has commercial value, won't you make much money?"
Xu Yi gave an explanation that shopkeeper Chen could not refute.
Shopkeeper Chen sighed and handed the prescription to Xu Yi in exchange for a thousand taels of silver.
Xu Yi glanced at it and stored the entire prescription into the memory palace.
"Shopkeeper Chen, I have a gracious request. I want to witness the process of refining the medicine with my own eyes."
"no problem."
Shopkeeper Chen pondered for a moment, then nodded in agreement.
Even the prescriptions have been sold, so it's nothing to watch the refining of the medicine once. Anyway, his prescriptions are not deceptive - mainly, he doesn't dare.
The dignified young master of the Xu family in Huayin County, if he really dares to cheat people with fake prescriptions, that would mean giving up the entire foundation. Although one thousand taels of silver was a lot, it was still far behind one of the best pharmacies in Huayin County.
Shopkeeper Chen took Xu Yi and others to the alchemy in the backyard.
When he opened the door, the strong smell of medicine immediately hit his nostrils, followed by a dry and hot breath.
In the refining pharmacy, there were several medicine boys watching the fire. Shopkeeper Chen waved them out, then turned to Xu Yi and said.
"Master Xu, refining the Shiquan Dabu Pill is not easy. It takes a day and a night. I hope you are mentally prepared."
What he meant by this was that he hoped that Xu Yi would arrange the people in advance and avoid any mistakes.
"One day and one night?"
Xu Yi hesitated slightly when he heard this.
He heard what Shopkeeper Chen meant, but he didn't take it seriously. He had no intention of letting anyone else come, he was planning to come on his own!
However, this time still caught his attention, and some of his original preparations had to be changed.
"Shopkeeper Chen, I want to open ten furnaces at the same time. Is there any problem? Don't worry, I will recycle all the refined Shiquan Dabu Pills at the price of five taels of silver!"
"This is a bit difficult, but if you stagger the time a little, you can still do it."
Opening ten furnaces at the same time is also a big challenge for him. However, considering that each furnace costs more than ten taels of silver, ten furnaces are more than one hundred taels. Shopkeeper Chen feels that this challenge can still be taken up!
More than one hundred taels of silver, it usually takes him two to three months to earn it.
Now you can make so much money in one day with just a little hard work?
Done!
······
Shopkeeper Chen immediately prepared ten medicine furnaces and corresponding medicinal materials.
"Master Xu, look, this is the most important ingredient of Shiquan Dabu Pill - ginseng. When choosing this ginseng, it is best to use ginseng that is twenty years old. This expenditure alone..."
“Every serving here is 20-year-old ginseng?”
"Huh? Yes, there may be a difference, but it won't be too big."
Shopkeeper Chen was stunned for a moment, then nodded.
Xu Yi didn't say anything, but took a little bit of each ginseng, turned on the 24 times serious state, and experienced it carefully.
After experiencing everything, he nodded.
"It's really not that big of a difference."
In order to prevent errors and omissions, he just opened the memory palace, and through replay and comparison, he proofread it three times in a row. He found that there may indeed be a slight difference in the medicinal power of these ten ginseng branches, but the difference is very small.
More importantly, this was very close to the feeling that the Shiquan Dabu Pill he had taken before gave him!
However, what Xu Yi was thinking about at this time was not the authenticity of the Shiquan Dabu Pill, but another matter that extended from it.
He can actually take the medicine and get the prescription directly?
"It's really unexpected that the Memory Palace has such a function."
"wrong!"
"It should be the serious state plus the memory palace. The two should be superimposed to achieve such an effect!"
If he were under normal circumstances, even if he remembered the taste experience at that moment, without strong enough perception and thinking ability, it would be difficult to compare them in such a short period of time.
"I feel like this ability is a bit powerful!"
"If I am willing, doesn't it mean that as long as I take this elixir, no, not just pills, but anything else, as long as I want, I can directly derive its formula!"
For example, the current Shiquan Dabu Pills, or the Huashan School's medicated diet, have the ability to reverse the process, and Xu Yi can reverse the complete formula.
Following the previous actual combat deduction, Xu Yi discovered a powerful function of Serious State + Memory Palace.
Recipe reversed!
Theoretically speaking, Xu Yi can use this ability to reversely deduce any formula.
Tonic formulas, poison formulas, medicated diet formulas······
You might even be braver and open your mind a little more.
Alloy formulas, gunpowder formulas, human body 'formulas', etc., etc., it is not impossible that these cannot be deduced backwards.
Even to a certain extent, martial arts, martial arts, and internal strength can all be a formula!
It is not impossible to reverse the 'recipe' of all martial arts and create your own 'small phaseless skill'.
It's just that these 'recipes' may sound relatively challenging to people's outlook on life.
Of course, these formulas cannot be deduced just by 'eating'. Watching, touching, smelling, etc. can all be used as corresponding means.
It can be said that this is a powerful function that can be extended indefinitely.
Even just such a function is enough to form a new and powerful golden finger!
"However, this function is not without problems."
At this time, Xu Yi was in a serious state. His powerful thinking ability allowed him to discover this powerful function and at the same time, he also discovered the problems behind this function.
It can’t be said to be a problem!
It is a prerequisite for using this function.
"This function is developed based on my own knowledge. If I want to fully utilize this function, I first need to have relevant knowledge myself."
Just like the Shiquan Dabu Pills just now, if Xu Yi hadn't personally eaten the 20-year-old ginseng and knew what the ginseng should look like, he would also have known that the 20-year-old ginseng needed to be used in the Shiquan Dabu Pills. Vintage ginseng?
That's obviously impossible.
