According to Geralson, this potion is his exclusive secret ingredient, and it costs a lot of money to use a variety of precious ingredients to concoct it, and the effect is far greater than any other potion of the same type on the market.

The main materials are: the brain nucleus of the Dementor, the slime of the bone-eater, the false heart of the mandrake, and the spinal cord of the spider motherworm. Just imagining the disgusting material, Leo was on the verge of throwing up.

As the viscous liquid flowed down his throat and began to squirm faintly, Leo let out a flurry of retching.

However, the liquid seemed to be unwilling to leave his esophagus, not only was it not vomited out, but continued to flow downward, and in a blink of an eye, it had already peristolen into his stomach.

"It's not poison for you, bear with it. Geralson said in a flat tone, "The first time you eat this, you will feel uncomfortable, and then you will slowly get used to it." Well, if it weren't for the fact that there were only ten bottles, I would have wanted to order it, and I really miss this familiar taste. ”

Leo did not respond. Actually, it's not that he doesn't want to, it's that he can't speak at all. He had no doubt that if he opened his mouth, he would definitely vomit again. And the only thing that is fortunate now is that the professor has never issued a warning, that is, this thing really does not cause harm to the body.

"Except...... Even professors can't detect its harm. Sure enough, perverted people like perverted things. Leo could only say this in his heart.

After a few minutes, the uncomfortable feeling gradually faded, but Leo didn't notice any change in his body.

Geralson saw what he was thinking, and said, "Don't worry, let the potion flow slowly, it will eventually enter your brain and give you an experience like never before." ”

"Into the brain?!" Leo was taken aback.

"Of course, but you can rest assured. After I blended it, there was not much activity left of the material, and when it reached the brain, the activity was completely depleted. Therefore, not only will the medicine not cause you any damage, but on the contrary, it will continue to nourish the brain. Geralson explained. Looking at the time again, he muttered, "It should be almost now, you should feel something, right?"

Leo carefully distinguished, shook his head and said, "I don't feel anything......"

As soon as the words fell, the professor's voice sounded in his consciousness: "Warning! An unknown polymer substance has been detected to be about to be absorbed by brain cells, and it is currently impossible to determine the possible consequences, please quickly determine whether to isolate it!"

Instead of responding to the professor immediately, Leo glanced at Geralson.

The High Mage was crazy about magic, but Leo didn't think he would joke with his life. And judging by the current situation. The other party must have tried this potion, and the effect is remarkable, so they will force themselves to use it.

With this judgment in mind, Leo said to the professor: "Absorption is allowed, but the absorption rate is controlled, first at one-tenth of the normal speed, and then all the possible consequences of absorption are analyzed." ”

"The order has been accepted and is being processed. The professor replied. There was silence.

On the other side, Geralsson looked at Leo. He frowned slightly. According to his memory and his own feelings, the potion should have begun to take effect at this time, but why didn't this kid feel it?

"Could it be that it has full resistance to the Brain Activation Potion? How is that possible?" Geralson couldn't help but start thinking about it, and even began to wonder if there was a mistake in the process of preparing his own potions, whether there was a mistake in the process that caused the potion to fail.

If that's really the case. Then you have to deal with it quickly.

In the case of incomplete configuration, the agent will not do any good, but it is likely to harm the brain. Perhaps, a craniotomy to extract the medicine is a good way.

Leo certainly couldn't have known that Geralson had already begun to figure out whether to get his head out of the way. He was listening intently to the professor's presentation.

"After analysis, it was concluded that the substance would cause the brain to enter a prolonged state of euphoria, with a significant increase in concentration and increased efficiency in the application of mental values, with an estimated duration of 72 hours. ”

"What about the danger, can't it be nothing?" asked Leo, a little uneasy. Because he knows that behind the good results, there are often more terrible side effects.

Sure enough, the professor quickly replied: "Since this substance stimulates brain activity, it will cause severe insomnia, and according to statistics, its effect is more than 130 times that of about 500 milliliters of coffee." "In other words, drinking this is equivalent to me drinking a hundred and thirty cups of coffee?" Leo smiled bitterly in his heart. It seems that Geralson really doesn't plan to put himself to sleep. But is there really no problem with going on like this? It probably won't be long before it will lead to a severe nervous breakdown.

At this point, Geralson finally couldn't bear it anymore and asked, "Nothing has worked?"

"Yes, I feel it. Leo replied hurriedly, and at the same time in his consciousness ordered the professor to be fully open to absorption. Now that you've decided that you want to accept the study plan, there's no need to leave yourself with any more ways to go back. As for possible problems, let's wait until they arise to solve them.

Hearing him say this, Geralson finally reassured, and put the idea of going to the Necromancy Laboratory to borrow a craniotomy tool behind him, and then asked, "What do you feel?"

"I feel that my head is very clean, and my memory seems to have improved, teacher, this potion really works!" Leo deliberately made himself look exaggerated, so as not to see any clues about the professor.

However, this sentence is not nonsense, because he does feel that his current state is very good, and if it is used for studying, he can definitely achieve twice the result with half the effort.

Geralson nodded with satisfaction: "In that case, let's start with the first project, you have two weeks to finish the books I prescribed." In this process, I will not give any guidance, and all the understanding will be up to you. In two weeks, I'll put you to the test. If you can't pass, then you're not eligible for the competition, understand?"

"Understood. Leo replied as he flipped through the long bibliography in his hand.

"Detailed Explanation of the Difference between Intermediate Magic and Primary Magic", "Systematic Construction of Fluid Magic Model", "Analysis of the Spell Casting Process of the Fire Elemental Sub-faction",
