Fat Uss took out a black wooden box from the back shelf and placed it on the tabletop, and took out a piece of parchment from under the counter, which looked old and had a few corners around it.

"One body elixir formula, one magic stone!"

"One raw material, enough to be refined ten times, one magic stone!"

Leylin opened the black box, and there were ten blood-red fruits neatly placed inside, with cracks on the surface, and a green plant rhizome next to it, and a bottle of black powder.

After putting the box away, I picked up the parchment paper again, and the pale yellow paper had some recipes written in black ink, as well as precautions, etc., although the handwriting was a little blurry, but it was generally clear.

Leylin nodded, took the parchment into his arms, handed the last two magic stones in the leather pouch on his waist to Us, and left the cabin without looking back.

He only had four magic stones on him, and he had completely spent them just a little bit of materials, and the terrifying consumption of pharmacy was really not something that ordinary people could bear.

Next, Thunderlin's life returned to the state of what it was before.

Every day, I run back and forth in five places: dormitory, dining hall, teaching building, real yàn room, and library.

More than a month passed unconsciously.

"Data collection complete!" came the sound of the chip.

Next to the long table in the library, Lei Lin closed the book in his hand.

In addition to listening to lectures and cooperating with the tutor, Lei Lin spent most of the rest of his time in the library, basically reading all the free books and improving the accumulation of information on the chip.

"Whew...... Finally got through the potion formula!" Lei Lin let out a long sigh.

Although Golfat passed on the knowledge of Lei Lin's primary pharmacy, he couldn't understand a lot of it, and there were many special terms, vocabulary, etc., all of which had to be found in the library, and if you wanted the tutor to answer it, you still had to charge for it, but unfortunately Lei Lin had become a poor bastard who didn't have a magic stone.

Access to free materials through the library is a common practice for many cash-strapped apprentices, but they don't have Leylin's chip, and it often takes more than ten days or even a month to find what they want in a mountain of books.

Up to now, Lei Lin has basically recorded all the books that can be read in the library, and established search entries, and if you encounter any problems in the future, you can directly search and solve them through the guò chip.

But elementary pharmacy is worthy of advanced fee knowledge, even if Lei Lin relies on the chip to continuously analyze, he can only understand one-third, but even if it is only one-third, it will be of great help to him.

At least, looking back at the fundamentals of pharmacy now, it feels a bit high-level.

And the body of the formula, which is just the basic elixir, has been completely parsed out, and you can start to try to actually make it.

"I've accumulated enough knowledge, so I'll start making the body elì potion tonight!"

Leylin put the books back on the shelves and left the library.

A female apprentice with long brown hair next to her raised her head, looked at Lei Lin, and then put her mental attention to the black book in her hand.

There are many apprentices in the library, but it is very well-behaved, very quiet, and suitable for reading, and it is one of Leylin's favorite places.

"Hey!

Walking out of the library, an apprentice greeted him, and Leylin looked up: "Good day!

Créwell was wearing the gray robe of an apprentice, and the original little pride dissipated a lot: "Congratulations on becoming a first-class apprentice!"

"Thank you, and congratulations!" replied with a smile.

In his induction, Créwell also became a first-class apprentice.

"The people in our circle have become first-class apprentices!" Créwell bit the first few words very hard, and seemed to automatically ignore the Gully and them.

"We've been on a few assignments lately, would you be interested in working together?" asked Créwell.

It seems that he has been working very hard to maintain the original small group.

"Going on a mission now?" Leylin frowned, "As far as I know, the vicinity of the academy is dangerous, especially for first-class apprentices who can't even cast spells......"

"No way, no matter what advanced knowledge is here, you have to charge for it, and only the magic stones we have brought are exhausted!"

"You're going to be a pharmacist, and it's a lot of resources to ......"

"I'll think about the task after the second-class apprentice! Be careful yourself!"

"Okay! I heard that you are teaching others to earn magic stones, can you teach us too, according to your previous price!"

Hearing that Leylin was reluctant to go, Créwell asked again with some pity on his face.

"Of course, gladly, and I can give you a discount!" Leylin smiled, the exchange of benefits has always been the code of conduct between wizards.

After the two sides set the time and place of the class, Créwell said goodbye and left.

Looking at his back, Leylin's eyes flashed: "Are you still trying to win over?" Unfortunately, Crewell hasn't understood that in the wizarding world, his own strength is the most important thing!"

Shaking his head, he went to the dormitory.

The dormitory of the Black Bone Forest Academy is occupied by each apprentice individually, and there is no problem with confidentiality and security.

Leylin locked the door and hung up the Do Not Disturb sign before coming to the room next to the bedroom.

It was filled with a large black table with the last instrument that Lei Lin had bought.

"I have practiced some hands before, and I am also familiar with these utensils, and today I have completely analyzed the formula of the body lì potion, and it is time to start!"

Thunderling muttered to himself, took the black box from the side of the room where the materials had been placed, and placed it on the table to open it.

Red fruits, green rhizomes, and a bottle of black powder all come into view.

Thunderlin's fingers ran over the surface of these three things, "Chip! Detect activity, build a model!"

"Start the detection, count the jù collection, start the modeling!"

"Conduct a simulation!" Lei Lin gave a new order after seeing that the chip had completed the task.

"Real yàn simulation...... Body lì drug configuration...... Estimated consumption time: 2 hours and 21 minutes!"

"Sure enough!" said Leylin, with a smile on his face.

Even if it is the same material, there will be differences in subtle individuals, and when refining medicine, the slightest difference in activity will cause different results.

A qualified pharmacist is to constantly deduce the following process and make adjustments through guò contact in order to obtain complete medicinal properties.

This only depends on talent, as well as a lot of experience accumulation in the later stage.

In the case of the chip, you can scan it first, and simulate it, and the success rate is definitely higher than that of many apprentices.

Lei Lin waited patiently for a long time before he heard the voice of the chip sound: "The simulation is completed, and the success rate is 23.6%"

"Close to a quarter success rate?" Leylin looked ecstatic.

"For ordinary apprentices, the first time they refine a medicine ends in failure, and as long as I follow the chip prompts at the beginning, I have a one-quarter success rate?"

"Start the process of transmitting the real yàn!"

"Start counting jù transmission!" Images flashed in front of Lei Lin's eyes, as if he had refined countless elixirs, and the responses to various sudden reactions and the processing of medicinal herbs all appeared in front of him one by one.

"Here we go!"

Lei Lin's face was solemn, and he picked up a red fruit, "This is the Blood Qi Fruit, which is rich in a lot of nutrients, but it just needs to be detoxified......"

Lei Lin put the Blood Qi Fruit in a white bowl, picked up a hammer, and mashed the Blood Qi Fruit, red juice gushed out, and a stream of wine continued to emanate.

After straining the mashed Blood Qi Fruit, Leylin poured the red juice into a beaker.

Lit the black candlestick below, a pale blue flame kept licking the bottom of the beaker, and as time passed, the red liquid in the beaker began to bubble, and a little black powder kept churning inside the foam.

Leylin picked up the glass rod and put it in the beaker, and began to stir constantly.

"Marius!" Reeling said a few syllables.

A trace of spiritual power stretched along the glass rod into the liquid that had begun to boil, and a little bit of black gas kept coming out, these were the toxins hidden in the Blood Qi Fruit.

This is why only first-class apprentices can start experimenting with pharmaceuticals, and some methods can only be used with energy particles.

After all the black gas was expelled, Lei Lin put the more vivid red liquid into a test tube.

"The first step is complete!

"Next, it's the root of Luoguo......"

Leylin then processed the other Blood Qi Fruit and Luo Fruit Roots, failing a few times in between, and finally obtaining eight tubes of red liquid and seven tubes of green jelly-like substance.

"Next, it's time for the final blending process!"

Leylin put a tube of green jelly into the petri dish, took out the glass bottle in the black box, picked out some black powder and sprinkled it.

The black powder reacted violently when it touched the green jelly, and the jelly began to expand and whine.

"Ice!" Raylin spat out spell bytes, Byron.

A white mist suddenly appeared around the petri dish, condensing into ice chips, freezing the green jelly inside.

"It's now!" Leylin poured ice into the beaker on the side, and the flames burned underneath.

"One last step!" Lei Lin's eyes widened, and he poured the Blood Qi Fruit Essence liquid into the red test tube.

The spiritual power also turned into a thread, which continued to extend into the beaker.

"Smack!" suddenly there was a sound in the beaker, and the jelly and red liquid instantly turned black, and a foul smell came out.

"Did you fail?" said Leylin, whose face was expressionless.

"Chip, analyze the reason!"

"Ding! Analyzing...... Conclusion: The mental power of the main body fluctuates unsteadily, and the flame temperature presents a chaotic curve......"

The chip kept replaying what Lei Lin had just done, and indicated the reason.
