Fatty Us took out a black wooden box from the shelf at the back and placed it on the table. He then found a piece of parchment from under the counter. It looked very old and had a few broken corners around it.

"A recipe for physical potion, a magic stone!"

"One raw material, enough to refine ten times, a magic stone!"

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

Put the box away, pick up the parchment paper, and the light yellow paper was written with some recipes in black ink, as well as precautions, etc. Although the handwriting was a bit blurry, it could be seen in general.

Leilin nodded, took the parchment into his arms, handed over the last two magic stones in the skin on his waist to Us, and then left the wooden house without looking back.

He only had four magic stones on his body, and he spent all the materials just by purchasing a little bit of it. The terrifying consumption of pharmacy is really not something that ordinary people can bear.

Next, Lei Lin's life returned to the previous state of the previous few points.

Every day, I run back and forth in five places: dormitory, restaurant, teaching building, laboratory and library.

More than a month passed without realizing it.

"The data is collected!" The chip prompt sound came.

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

Except for listening to the class and cooperating with the tutor's experiment, Lei Lin spent most of the rest of the time in the library, and basically read all the free books to improve the accumulation of chip information.

"Huh... I finally got the medicine formula!" Lei Lin breathed out.

Although Guofat passed on to Leilin's primary pharmacy knowledge, he couldn't understand many of them. There were also many special terms, vocabulary, etc. that had to be found in the library. If you want a tutor to answer, you would still have to charge a fee. Unfortunately, Leilin has become a pauper who has no magic stone.

It is a common practice for many cash-strapped apprentices to check free materials through libraries, but they do not have Leilin's chips. It often takes more than ten days or even a month to find the content they want in a mountain-like book.

Until now, Lei Lin has basically recorded all the books that can be read in the library and established search entries. If any problems encounter in the future, they can be solved directly through chip search.

But elementary pharmacy is worthy of being a high-cost knowledge. Even if Lei Lin relies on chips to continuously analyze, he can only understand one-third of it. But even if it is only one-third, it will be of great help to him.

At least, looking back at the basics of pharmacy, I feel a bit broad-minded.

The physical potion formula of only the basic potion has been completely parsed out and you can start trying to make it.

"I have accumulated enough knowledge, so I will start to produce physical potion tonight!"

Leilin put the book back on the wooden shelf 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 attention on the black book in her hand.

There are many apprentices in the library, but they are very disciplined and quiet, and are very suitable for reading. They are one of Leilin's favorite places.

"Hi! Raylin!"

Walking out of the library, an apprentice greeted him, and Raylin raised his head: "Ri'an! Claywell!"

Claywell wore an apprentice's gray robe, and his original pride dissipated a lot: "Congratulations on becoming a first-class apprentice!"

"Thank you, congratulations!" Lei Lin responded with a smile.

In his senses, Claywell also became a first-class apprentice.

"The people in our circle have become first-class apprentices!" Claywell took the first few words very seriously, and seemed to have automatically ignored Gu Licha and the others.

"We have taken on several tasks recently. Are you interested in joining us?" Claywell asked.

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

"Just go on the mission now?" Leilin frowned. "As far as I know, it is very dangerous near the academy, especially for first-class apprentices who can't even release spells..."

"There is no way. No matter what advanced knowledge is, you have to charge for it, and you only charge for magic stones! The magic stones we brought have been exhausted!" Claywell smiled bitterly.

"If you want to become a pharmacist, the resources in this area are very expensive..."

"I'll consider it after the second-class apprenticeship! Be careful!" Lei Lin still refused. Although the harvest after completing the task was very attractive, he still had to be able to get the chance.

"Okay! I heard you are earning magic stones for others. Can you teach us too, at your previous price!"

Claywell asked again when he heard that Relin was unwilling to go.

"Of course, I am happy, and I can give you discounts!" Lei Lin smiled. Exchange of interests has always been the code of conduct among wizards.

After both sides set the time and location of class, Claywell said goodbye and left.

Looking at his back, a light flashed in Leilin's eyes: "Are you still trying to win over? Unfortunately, Claywell didn't understand that in the wizard world, his own strength is the most important thing!"

Shaking his head, he came to the dormitory.

The dormitories of Black Bone Forest College are all occupied by each apprentice, and there is no problem with confidentiality and security.

Lei Lin locked the door and hung up the Do Not Disturb sign before he came to the room next to the bedroom.

It was filled with a large black table, with the instruments that Lei Lin bought last time.

"I was familiar with these utensils through some practice before. Today I have completely analyzed the formula of physical potion. It's time to start!"

Leilin said to himself, taking the black box that was originally placed on the table from one side of the room and opening it.

Red fruits, green rhizomes, and a bottle of black powder all appeared in front of you.

Leilin's fingers stroked the surface of these three things, "Chip! Detect activity, build a model!"

"Start detection, data collection, modeling begins!"

"Conduct simulation experiments!" After Lei Lin saw that the chip had completed the task, he issued a new command.

"In the experimental simulation...the physical agent configuration...the estimated time is: 2 hours and 21 minutes!"

"It's true!" Lei Lin's face was filled with smiles.

Even the same material will have differences in subtle individuals. When refining medicine, a slight difference in activity will lead to different results.

A qualified pharmacist must constantly deduce the subsequent process through contact and make adjustments to obtain complete medicinal properties.

This only depends on talent and a lot of experience accumulation in the later stage.

On the chip, you can scan first and simulate the experiment, and the success rate is definitely above many apprentices.

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

"Near a quarter of success rate?" Leilin looked ecstatic.

"For ordinary apprentices, the first time they refine medicines in failure, and at the beginning, I had a one-quarter success rate as long as I followed the chip prompts?"

"Start the transmission experiment process!"

"Start data transmission!" Images flashed in front of Lei Lin's eyes, as if he had refined physical potions countless times, and various sudden reactions and treatment of medicinal materials all appeared in front of him.

"here we go!"

Lei Lin looked solemn and picked up a red fruit, "This is a blood qi fruit, rich in nutrients, but it needs to be treated with detoxification..."

Lei Lin put the blood and Qi fruit in a white bowl, picked up a pounding hammer, and mashed the blood and Qi fruit. The red juice poured out, and a smell of alcohol continued to spread.

After the crushed blood and qi fruit was filtered, Leilin poured the red juice into a beaker.

The black candlestick below was lit, and a light blue flame kept licking the bottom of the beaker. As time passed by, the red liquid inside the beaker began to bubble, and a little bit of black powder kept churning in the foam.

Leilin picked up the glass rod on one side and put it into the beaker, and began to stir continuously.

"Marius!" Relin read out several syllables.

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

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

Only after all the black gas was discharged, Lei Lin put the brighter red liquid into a test tube.

"The first step is done! The purity is good!"

"Next, the root of Luoguo..."

Lei Lin then treated the other blood and Qi fruit and the root of Luoguo. He failed several times in the middle and finally obtained eight tubes of red liquid and seven tubes of green jelly-like substances.

"The next step is the final deployment process!"

Leilin put a tube of green jelly into the Petri dish, took out the glass bottle from the black box, picked some black powder and sprinkled it on.

The black powder reacted strongly when it touched the green jelly. The jelly began to expand and made a whimpering sound.

"Ice!" Leilin spit out the spell byte, which was Byron.

A white mist suddenly appeared around the Petri dish, condensed into borneol, and the green jelly was frozen inside.

"It's now!" Leilin poured the ice into the beaker on the side, and the flames underneath kept burning.

"The last step!" Lei Lin widened his eyes and poured the essence of Blood Qi Fruit in the red test tube into it.

The mental power also turned into a slight thread and continued to extend into the beaker.

"Bang!" A sudden sound came from the beaker, and the jelly and red liquid turned black in an instant, and a foul smell was emitted.

"Has it failed?" Lei Lin's expressionless face.

"Chip, analyze the reasons!"

"Ding! Analysis... Conclusion: The subject's mental power fluctuates unstable, and the flame temperature shows a chaotic curve..."
Chapter completed!
