Although he hasn't really started to evaluate yet, Serra actually knows who has a good effect on the potions he refines and who has a bad effect on the potions he refines.

The most important thing for a drug is the efficacy, and what are the ultimate reasons that can determine the efficacy? Under the same formula, it is nothing more than the quality of the material and the quality of the configuration method.

The higher the quality of the alchemy materials, the better the efficacy of the elixir, and the faster and more correct the operation method, the least loss of efficacy in the process of configuration of the elixir, and the alchemy materials will also remove harmful components and toxicity after processing, so as to minimize possible adverse reactions and side effects.

In terms of the choice of potions, the ones that impressed Sierra the most in this class were the apprentice Al in the cloak and the black-haired boy Longchen.

In terms of the refining operation of the potion, the dwarf boy Jerden and the bespectacled girl Xili can be said to be quite good, especially Longchen makes Serra feel particularly amazing.

Judging from these two decisive points, it is self-evident who has the best alchemy talent among the apprentices.

Serra began to evaluate the apprentice's alchemy finished refreshment potion, and gave the corresponding advice, if anyone paid attention to Serra's route, it was not difficult to find that the direction of the end point was where Longchen was.

"There are too many residues of the potion, maybe the Fika beans are not crushed enough, or the calyx of the Azuro flower is burned, so there is no need to taste such a potion. ”

Putting down the potion in her hand, Serra gave a comment and continued on to the next apprentice.

The color of the potion in his hand was a little strange, and Serra shook it, put the potion test tube to her lips and gently sipped it, frowning:

"The amount of wisteria is too much, and the bitterness is very strong, are you sure that others are willing to drink such a potion?"

When she walked next to the dwarf boy Jerden, she saw that the liquid medicine in the test tube was a uniform light brown translucent liquid, and her face finally showed a little expectation, she picked up the test tube and gently tapped the liquid medicine with the tip of her tongue, and the familiar cold feeling came from the tip of her tongue, accompanied by a special smell of medicine.

"Very good operation method, it is already very good that the original more general materials can achieve such an effect, but it is a pity that the alchemy materials are not selected to be the best. ”

Serra commented.

"But teacher, you didn't tell us what potions we need to refine in this class and what materials we will use?" Gelden asked innocently, rubbing his nose.

"Do you think I should tell you in advance?"

Serra's rhetorical question left Jerden speechless.

Finally, Serra walked up to Long Chen.

The black-haired boy sat behind the alchemy table and looked quietly, and judging from his calm appearance, it seemed that he did not expect anything from Serra to come over for identification.

This only made Sierra more curious.

The medicinal liquid that Long Chen had refined was placed on the alchemy table, the difference was that it was not contained in an alchemy test tube, but in four small medicine bottles.

Seeing this scene, the corners of Serra's mouth brought a smile.

"Are you so confident? The bottles are ready. ”

If the apprentices around them had had a little experience in dealing with things, they might have been able to hear that Serra's words were different from what she had said to the others before.

There is no way, teachers always prefer good students.

"If you're referring to such a simple potion, then of course. ”

Long Chen's answer was full of momentum.

He did have the confidence to do so.

If it's magic, I may not be good at it, but how can I be worse than these natives in this kind of thing that is similar to the chemical reality of concocting potions?

Serra smiled, the bottle of potion was placed in front of her for a few inches and pinched in the air, through the thin glass bottle, you can see that the liquid medicine is a clear translucent light brown liquid, if you deviate the bottle slightly, the liquid will flow slowly, obviously this liquid has a certain viscosity.

The purity is very good, and the concentration is also quite good.

If it weren't for the habit, Serra would have praised the apprentice at this point.

She snapped the cap of the bottle, and a cool smell of medicine came.

Instead of tasting it with the tip of her tongue like she had done the first few times, Serra took a small bite and closed her eyes.

"Perfect. ”

When Serra reopened her eyes, she gave a straight comment.

Long Chen smiled as a matter of course, and the apprentices around him looked at him, envious, respectful, or whatever.

Long Chen felt as if he had found a little bit of a feeling like being the protagonist of a novel.

For Serra, the appraisal of this apprentice named Longchen should be the best of this appraisal, she didn't expect that this apprentice would be able to refine the potion to this Cheng dù, although it is only a refreshing potion, but this potion will definitely get the highest rating of similar potions no matter which pharmacy in Valari it gets.

This is definitely a treasure trove to be found.

Somewhat distracted, Serra walked to the next apprentice's alchemy table, only to find that it was the cloaked boy Al.

There was also a potion on the alchemy table in front of Al, and at first glance, it seemed to be in good condition.

But because he had already received the most perfect answer from Long Chen before, Serra had no way to raise his interest anymore.

She picked up the potion, and without any further identification, she put it to her lips and tapped it with the tip of her tongue.

There is something strange about the taste......

It should be that there is something wrong with the alchemy technique, I clearly remember that this apprentice uses the best materials, when the apprentices were refining potions, Serra focused on Long Chen most of the time, so he didn't pay so much attention to this cloak apprentice Al.

What to say?

Putting down the potion, Serra, who was about to organize the language, suddenly widened her eyes.

That's not right!

The cold feeling of the little liquid that I had just tasted didn't seem to have dissipated, but continued to linger on the tip of my tongue, and there were signs of continued expansion!

How can it be?

Before, he had obviously tasted the most perfect potion refined by Long Chen, and the elixir refined by El should no longer work, but now the fact is that this is not the case at all, could it be said that the medicinal effect of El's potion is even better than Long Chen's?

"Bring me your alchemy materials. ”

Serra calmed down and commanded.

Al handed it to her.

It is indeed exactly the same as what Long Chen used, how is this possible?

Serra frowned, puzzled, and then she thought of another possibility.

"Can you give us an overview of your alchemy steps?"

Al nodded, and began to speak.

Serra interrupted him with some trepidation when he heard Al say that the calyx of the Sulo Flower was not heated, but simply squeezed out of the juice, crushed and then soaked in a large amount of water.

"You haven't heated it, do you know that the calyx of the Sulo flower is poisonous?" asked Serra, pale.

"Of course, I'm also a detoxification treatment. Al replied calmly, and then added, "The water detoxification method is also a recognized detoxification method, and I have personally verified that it is effective when used here. ”
