Although Charlotte's experiment can not completely overthrow the fire element theory, it at least proves from the side that this theory, which has been used for 300 years, has loopholes, which makes teacher Claire waver.

In his next experiment, Lena completely denied the traditional combustion theory, and saw it with his own eyes.

She felt dizzy. This is the magic backfire caused by the shaking of willpower. Such a situation is very rare. It will only appear when a certain idea of the mages as the foundation is impacted.

It is said that in ancient times, due to the establishment of many innovative systems, there were mages who died directly because of such impact. But in modern times, with the gradual improvement of people's acceptance ability, no matter how novel the theory is, it will not lead to the recurrence of that kind of scene, but this kind of backfire happens from time to time.

"What's the matter with you, Mr. Claire?"

At this time, he realized that the woman's body was too light and soft. After making her sit down, Lena quickly released her hand.

"I'm fine, just a little dizzy."

Mr. Claire has no time to consider whether Lena takes the opportunity to take advantage of it. She has some strength to take it off. At the same time, she realizes that her initial fierce words may be a revolt against the overthrow of her familiar theory from the bottom of her heart.

"Bring me my kettle..."

hearing teacher Claire's words, Charlotte looks at the kettle by the table and brings it to me in a hurry.

This is the kettle she carries with her. According to Lena's memory, it should be some special potion made by herself, which can cure teacher Claire's old problems.

But when he opened the lid, Lena smelled something familiar.

"Sweet?"

It was a sweet and greasy smell. When Lena saw that she poured the brown black liquid in the kettle into the glass and poured it down, Claire recovered a little bit. She couldn't help being curious.

"Well, Mr. Claire, can I try some of your medicine?"

As soon as Lena's words came out, the atmosphere at the scene was a little awkward.

Charlotte didn't know what to say, but Mr. Claire had a few blushes on her cheek.

"Are you making fun of me, Mr. principal?"

She asked, as if she thought that Lena was taking the opportunity to tease herself.

"No, no, because I feel like your potion seems that I've seen it somewhere, so I want to make sure that if there's anything offensive, I apologize."

Lena quickly explained that he didn't want to get rid of the favor he had managed to build.

Perhaps she had never seen Lena's humble attitude before, but she was a little embarrassed for her arbitrariness. She poured some medicine into an empty water cup and pushed it to Lena.

"In advance, it's not trusting you, it's just asking me to give it to you."

When he heard what Mr. Claire said, Lena had no choice but to smile. Then he picked up the glass and took a taste of the medicine.

At once, there was a spark in Lena's mind. He opened his eyes slightly and stood still.

Seeing what he looked like, Mr. Clare quickly put away his kettle and murmured to himself.

"He asked for it himself. I didn't force him to...

" headmaster? "

Charlotte's fingers shook in front of Lena, which made him recover and stare at the brown black liquid in the cup.

If there is no problem with the taste of Lena, it should be a special kind of sugar water with moderate sweetness and good taste.

And the old problem of Claire, who needs regular sugar supplement, seems to be that his hypoglycemia didn't run away.

But that's not the point. It's something else that comes to Lena's mind.

He got up, went to the experimental platform, and mixed the carbon dioxide they had just collected with the sugar water with a simple alchemy array. You can see that the sugar water soon began to come out with bubbles, like coke on earth.

"Can you freeze this for me?"

Lena said to Mr. Claire, pointing to the two glasses of liquid mixed with carbon dioxide.

Feel suspicious, but did not say anything, Claire teacher immediately cast a lower temperature spell, make the cup surface with a layer of white frost.

Looking at this familiar thing, Lena felt nostalgic and sipped the soda.

There is no doubt that this is more than 80% similar to coke on earth.

Praise chemistry.

Seeing the intoxicated expression on Lena's face, Mr. Claire was a little strange. After his potion was added with that special gas, would it really taste good?

Noticing teacher Claire's eyes, Lena immediately handed her another cup.

"Do you want to try?"

Teacher Claire hesitated. On the one hand, this is her potion, and the strange gas has no taste. The combination of the two will not have a special effect. On the other hand, the bubbling potion seems to exude some magic, which makes her eager to try.After thinking about it, Mr. Claire took the cup and sipped the cold liquid.

“!!!”

An unprecedented feeling suddenly enveloped the teacher.

There seemed to be fireworks blooming on the tip of her tongue. The stimulating feeling filled teacher Claire's mouth. For a moment, she even wanted to spit out the liquid in her mouth.

But the next moment, fresh and accompanied by sweet taste wrapped her throat, the original fierce impact disappeared, turned into a cold wave, endless aftertaste, until all swallow, Claire teacher still has a sense of trance.

With her eyes closed, Claire felt that she had come to the clear and cold pool. The feeling of contentment and contentment penetrated into her body through her skin, making her feel that she was about to turn into running water and melt in it.

She felt as if she could float up and fly into the sky at any time. For a moment, she even suspected that Lena had given herself some psychedelic drugs.

But this is clearly the taste of his own liquid medicine, but because of the irritating gas and the strong impact after freezing, teacher Claire lost himself in it.

Seeing teacher Claire's expression, Lena knew that this kind of drink had an irresistible charm for people in the world. He handed the cup that teacher Claire put down to Charlotte and motioned the student to taste it.

Charlotte took the cup, looked at the bubbles in it, and then took a sip. She could see that her eyes suddenly widened in the liquid filled with bubbles.

Carbonic acid is separated from sugar water and turned into carbon dioxide, which absorbs a lot of heat and makes Charlotte feel cool and comfortable.

The original ordinary sugar water, after this treatment, actually has a stimulating feeling, let Xialuo spirit immediately.

It can be said that she has never drunk such a drink.

For a moment, Charlotte seemed to be on the snowy plain of brunhilde in the extreme north. A sharp wind blew away the heat of early summer, from her throat to her stomach, and then spread to her whole body, which almost made her cry in a low voice.

But Charlotte still restrained her impulse to drink it all. She looked at the bottle with regret and had to admit that the drink really had some magical power, which prompted her to take another sip.

"What the hell is this?"

Charlotte asked.

"Teacher Claire's Potion, as you can see."

Lena looks at Mr. Claire, who is still immersed in the dreamy smell of soda, and explains.

"It's just that I added this special gas and chilled it, so it has a different taste. In my hometown, there is a similar drink that does the same thing. If you like, you can call it coke."

Crescent college is located in a remote place, while Lena comes from a big city. No one doubts that he has ever seen any strange food or play.

By reading the memory, he thought of more things, and then he changed the subject.

"I think it can be used as a source of school funding."
