"There are many ways to classify poisons, such as the most common one, which is based on source and purpose."

Xibeier took a piece of unknown branch, cut it with scissors, squeezed out the juice inside and continued: "Natural ones include plant toxins, such as poisonous mushrooms, cassava, bitter almonds, ginkgo nuts, etc...."

"Animal toxins, such as pufferfish, poisonous snakes, spiders, etc."

"There are also poisons that are extracted and condensed. The most common ones are the pesticides used by farmers to kill weeds and insects."

This is a laboratory in Adolf's manor, now used as a living room for pharmacy lectures.

Carl held a quill pen in his hand, nodded and took notes, and occasionally helped to process the medicinal materials.

"You have a good habit of taking notes."

Sibel picked up a glass bottle, gently shook the liquid inside, and praised: "The mentor once said, never put down the pen and ink, they are better than your brain."

A good memory is not as good as a bad pen.

There is a similar saying here.

"In addition to the previous classification, I prefer another one."

Hibern continued:

“Classification based on toxic effects.”

"It can be roughly divided into blood poison, nerve poison, corrosive poison, enzyme poison... This way, the antidote can be more targeted."

As he spoke, he handed over the test tube with half of the medicine in it.

"Try it."

"This is the paralysis poison I prepared. It can make a knight's squire's body stiff and lose the ability to resist for a short period of time."

?

Carl's face turned pale:

"Do you really want to try it?"

"Of course." Sibel said as if it was a matter of course:

"There is no better way to learn the principles and combinations of potions than to try them yourself. Moreover, trying more can increase the body's resistance to poisons."

"It will also be easier to learn the sorcery 'poison immunity' later."

"Okay." Carl sighed helplessly, forcibly suppressed the uneasiness in his heart, took the poison and drank it in one gulp.

He has tried several potions in the past few days.

According to Hibel, this immersive experience is the most efficient learning style, and it is also the style she learned from her mentor Adolf.

After just a few breaths, Carl felt his breathing quicken and his body began to become stiff.

"How about it?"

Xibel smiled and said, "Do you feel it?"

Carl's face flushed and he nodded with difficulty. He staggered to the test bench and began to prepare the potion.

Not long.

He drank the potion he had mixed, then his body went limp and he collapsed into the chair, gasping for breath wildly.

"good!"

Xibeier tapped his hands lightly and said, "It seems that you have completely mastered the knowledge taught in class yesterday. You did not make any mistakes in preparing the potion even though your body was paralyzed. I was planning to help you remove the poison."

Carl was too exhausted to respond.

After a period of contact, he also had some understanding of Xibel's character.

In essence.

Sibel is a girl who is full of curiosity about the world, but because of her education, she is very cautious about the outside world.

So I am confused most of the time.

When you first meet her, you will feel that she is cold and distant, but it will be easy to get close to her once you get to know her.

After all, she is just a teenage girl, how deep can her thoughts be?

"Ding-ling-ling..."

The bell rang for the end of get out of class.

Xibel stopped and held out his hand with a smile:

"Today I had three classes in total, and two potion recipes, for a total of twelve gold coins."

“Twelve?” Carl’s face turned pale.

I don’t know if it was because the toxins in my body had not yet been cleared or if I was just scared by the number, but I was speechless for a long time.

Knowledge is valuable.

It was only after he entered the wizarding world that he had the deepest feeling about this.

Even if it is needed for class, the pharmacy formula must be paid for, and different formulas have different prices.

and,

Even the materials used in class have to be paid for by yourself.

In short, money is required everywhere.

Even though he brought back a lot of things from the other world, the gold coins he got in exchange were being consumed at a speed visible to the naked eye.

I can only sigh at the moment.

"I'll bring it to you in two days."

"That's fine."

Thanks to his previous good reputation, Sibel didn't care about his debts.

"Sibel."

The door of the classroom opened, and a beautiful woman walked in: "Your tutor wrote to me, and mentioned something very important. Come and take a look."

Carl stood up and saluted:

Catherine is Adolf's wife, and in the semantics of the Kingdom of Gondor, this name symbolizes purity.

Unlike old Adolf.

Catherine was not yet thirty, the best age for a woman, and she was extremely beautiful.

Among the many women Carl had met, when it came to eyebrows, perhaps only Lady Anne, who was popular among thousands of men, could compare with him.

“Carl.”

Catherine nodded: "Would you like to stay for dinner today?"

“No.” Carl shook his head: “It’s too late to go back. It will be unsafe on the road.”

"You can stay here." Catherine said with a smile:

“There are a lot of empty houses on the estate.”

"No need to bother." Carl still shook his head and refused.

"Oh well."

Katherine shrugged.

She was quite satisfied with Adolf's new disciple, who had always been very respectful to her.

Not like Tim.

He appears to be a gentleman on the surface, but his eyes are evil and he often looks at me secretly, which makes me feel very uncomfortable.

* * * When we returned to our residence, Jenny had already prepared dinner.

Her cooking skills are getting better and better.

Carl was not polite. His rent included food and laundry, which was normal in the Kingdom of Gondor.

bedroom.

Carl packed up all the collected supplies, then walked to the fragment of the divine domain as he knew the way.

"finally……"

"I got the potion formula!"

These days, he followed Sibel to learn alchemy, firstly to master the knowledge, and secondly for the recipes.

The potion formula that uses undead dust as the main ingredient and can increase the mental strength of wizard apprentices.

The light of wisdom!

This is the name of the recipe.

The preparation of medicines requires extremely strict requirements on the sequence, timing, and proportion of materials.

The slightest mistake could cause the medicine to become ineffective at best, or explode or turn from a tonic into a poison at worst.

And precision is precisely Carl's specialty.

In the fragment of the divine domain, he can control his own power precisely and ensure that there are no mistakes when deploying it.

Moreover, if the fragments of the divine domain are mixed, the impact of the external environment can be minimized.

"20% diluted honey, crushed purple lotus, and seven grams of crystal fragments of top purity..."

Glassware, test tubes, oil lamps...

Various laboratory instruments are neatly arranged one by one.

"puff!"

A cloud of black smoke came out, announcing the failure of the experiment.

Carl remained unmoved.

Even though he had precise control over his own strength, he was not familiar with the proportions of the potions.

It is extremely unlikely that the first deployment will be successful at one go.

Failure is inevitable.

Pick up the quill pen and record the experimental data on the side.

"Attempt 2. Increase the weight of the crystal fragments, delay the time of adding the undead dust, and record the data."

"puff!"

"Attempt three, processing the purple lotus rhizome..."

"Bang!"

A ball of fire exploded, causing some utensils to break into pieces. Fortunately, Carl was well prepared and had bought spare parts in advance.

"Attempt thirty-seven, honey solidification degree two, number of undead dust seven..."

"clatter!"

As a few drops of liquid flowed into the test tube, Carl understood why this potion was called the Light of Wisdom.

The ground crystals glowed faintly after being dissolved.

Gently shake the test tube, and it seems to be shining with colorful lights, so beautiful that people can't help but be fascinated by it.

“Hmm…”

"It should be the effect of the undead dust. The light of the potion has a certain charm."

Putting down the test tube, Carl continued his experiment.

soon.

"One portion of undead dust can be used to mix two portions of light of wisdom. The other materials cost six gold pounds."

"Next..."

“Try the effect!”
