After a month and a half of lockdown, the academy, which had been closed due to the tragedy in the southern city and the holding of magic seminars, reopened.

"I miss it, I haven't been here in years, right?" Albert stared at everything familiar and unfamiliar in the academy, and said with emotion.

He didn't expect that one day he would step here again as a student and attend classes in the same academy with his son.

Although it was a bit of a stretch, Albert came, not because he could learn much, but because he wanted to take the opportunity to make some connections with the gifted Lord Lynn.

There were not a few people who had the same ideas as Albert, so there were two hundred official wizards returning to school this time, and there were countless wizard apprentices.

"Good afternoon, welcome back to school, I'm Lynn, the new dean of Iyeta Academy!" Lynn stood in front of the podium, smiling at the wizards who filled the classroom.

"It's an honor to meet you, Lord Lynn." Albert was the first to get up and salute back.

The wizards present also hurriedly stood up and saluted, not only because of the relationship between the professor and the students, but also because the other party was now the leader of the Iyeta school.

"Sit down, you're all formal wizards, and you all have unique insights into magic, and I'm just going to take this course to explain what I know and summarize the laws of the elements, for you to discuss, and I call it a chemical ......."

Lynn didn't assert her identity and put on a swaggering attitude, and asked the elves to hand out the textbooks as she spoke.

Albert looked curiously at the beautiful cover of the book in front of him, the whole book was actually made of that special white paper, and reached out to open the first page, on which was written in vigorous and powerful handwriting - [Chemistry is a natural discipline that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels. 】

"Dean Lynn, what do you mean by atoms and molecules?" A wizard asked, slightly puzzled.

"Atoms are the smallest particles that make up elemental and compound molecules, which we often call elements." Lynn explained. "Molecules, on the other hand, are made up of atoms and are the smallest particles of a chemical reaction......"

Lynn raised her hand, and a small water mass quickly appeared in front of everyone's eyes, "For example, water is formed from many water molecules, and the elements that make it up are hydrogen and oxygen...... The chemical formula is H2O, also known as dihydrogen monoxide......"

"Isn't that Il and Furla?" There was a slight discussion from the audience, this is the name of the Wizarding Lands for hydrogen and oxygen, and it is said that it is named after the two wizards who discovered them in a long time.

"How much do you know about hydrogen and oxygen?" Lynn asked again.

"[Il], no, oxygen is the source of life, and if an ordinary person who can't do magic is left in an oxygen-free environment, he will die quickly." Albert said with a deep groan.

For example, the three-ring magic [Life Forbidden Zone] is to create an oxygen-free environment and let the enemy die in a painful struggle.

"Both elements can be used to unleash fire magic...... another wizard added.

"What about the other than that?" Lynn continued to ask.

Albert frowned slightly. "Could it be that you are asking how many types of magic require these two elements?"

"No, I'm referring to their chemical formula, boiling point, density, application, specific heat capacity, critical temperature......" Lynn casually burst out a long list of nouns, and everyone was stunned.

"Hydrogen, for example, because it has a very low density, when a large amount of hydrogen is charged into an object, it can suspend the object." As Lynn spoke, she transformed a large amount of hydrogen in her magic power, binding it around her, and her body quickly drifted off the ground.

The wizards present were shocked to see this, which means that they might be able to use hydrogen to develop flying magic?

"Did you build an airship that uses hydrogen to levitate?" Albert thought of this immediately.

"No, hydrogen is a flammable substance, and if it is used to make an airship, it will turn into a fireball in the sky if you are not careful!" Lynn shook her head. "So I'm using a different element, and I'll explain it in more detail later."

Immediately afterward, Lynn created a giant ball of magic mixed with hydrogen and oxygen, and launched it out of the window.

The orb burst open under a banyan tree, and a large amount of gas stored inside erupted, followed by a fireball......

A violent explosion soon rang in everyone's ears, and the flames and flames flew high, and the poor banyan tree had been blown into two parts, and the surface of the tree was full of pits, and the ignited stumps and broken leaves were scattered all over the ground, and the soft ground was blown out of a huge crater.

The wizards in the classroom looked out the window, and they were stunned, this already had the destructive power of ordinary three-ring magic, and the process of casting spells was not complicated, even if a one-ring wizard could easily do it.

"The optimal ratio of hydroxide reactions is two to one, and it only takes a small flame to cause a violent explosion, and the product of them is water ......," Lynn calmly explains.

The wizards present hurriedly recorded this new combination of magic, and only then did they understand that this so-called chemistry class was to study the nature of the elements and the principles of magic, so as to develop a new type of magic.

Albert was flipping through the chemistry book in his hand, looking at the explanation of various elements on the page, and fell into a deep shock.

It seems that the [Secret Law Society] understands the elements far beyond their imagination, this is not in detail, but the various characteristics of the elements are studied clearly.

What Albert didn't know was that Lynn did not mark the atomic weight, period, electron configuration, atomic structure and other factors, considering that the composition of the two worlds may not be the same, and it had not been confirmed by experiments.

Lynn also had the idea of asking these wizards to verify it for him, because he was too slow to study alone.

Just as Lynn was about to fully explain the other properties of the element, there was a sudden sound of hurried footsteps outside the door, and then the door to the classroom was opened.

Albert and the others looked over with displeasure, they were immersed in the great thought of exploring the nature of the elements, but their thoughts were interrupted by the sudden sound of the door opening.

Which one of them is not long-sighted and dares to disturb them at this time?

Lydia was the one who hurried in, and the halfling girl shouted with joy and excitement on her face.

"Dean Lynn, Internal Combustion Engine...... We've made the magic internal combustion engine! ”
