After being closed for a month and a half, the academy, which had been closed due to the Nancheng District massacre and the holding of magic seminars, reopened.
"I really miss you. I haven't been here for many years, right?" Albert said with emotion as he stared at everything familiar and unfamiliar in the college.
He never thought that one day he would step here again as a student and attend classes in the same college as his son.
Although this feeling was a bit jarring, Albert still came, not so much to learn more knowledge, but because he hoped to take this opportunity to establish some relationship with the talented Mr. Lin En.
There are not a few people who have the same idea as Albert, so there are two hundred official wizards returning to school this time, and there are countless wizard apprentices. Due to the large number of people, he is the only teacher, and Linn has no choice but to Teaching is not conducted in batches.
"Good afternoon, welcome back to school. I am Lin En, the new dean of Iyeta College!" Lin En stood in front of the podium, looking at the wizards filling the classroom, and smiled in greeting.
"It's an honor to meet you, Mr. Linn." Albert stood up first and returned the greeting.
All the wizards present also quickly stood up and saluted. This was not only because of the relationship between the professor and the student, but also because the other person was now the leader of the Iyeta School.
"Everyone, sit down. You are all official wizards. You must have unique insights into magic. I only want to explain the laws of elements that I understand and summarize for everyone to discuss. I will call it For chemistry…”
Lin En did not maintain his identity and put on a arrogant attitude. As he spoke, he asked the goblins to hand out the textbooks.
Albert looked curiously at the exquisite book cover in front of him. The entire book was actually made of that special white paper. He reached out and opened the first page. On it was written the preface in vigorous and powerful handwriting - [Chemistry] It is a natural discipline that studies the composition, structure, properties, transformation and applications of matter at the atomic and molecular levels. 】
"Dean Lin En, what do atoms and molecules mean?" a wizard asked with a hint of confusion.
"Atoms are the smallest particles that make up single substances and compound molecules, which are what we often call elements." Linn explained. "And molecules are made up of atoms, which are the smallest particles in chemical reactions..."
Lin En raised his hand, and a small water ball soon appeared in front of everyone's eyes, "For example, water is made up of many water molecules, and the elements that make it up are hydrogen and oxygen... The chemical formula is H2O, also called oxidation monoxide Dihydrogen..."
"Isn't that [El] and [Fura]?" There was a slight discussion from the audience. These are the names of hydrogen and oxygen elements in the wizarding land. It is said that they were discovered by two people in a long time ago. Named after the wizard.
"How much do you know about hydrogen and oxygen?" Linn asked again.
"[El], no, oxygen is the source of life. If an ordinary person without magic is placed in an oxygen-free environment, he will die soon." Albert said thoughtfully.
For example, the three-ring magic [Life Forbidden Zone] creates an oxygen-free environment, allowing the enemy to die in painful struggle.
"Both elements can be used to release fire magic..." Another wizard also added.
"Apart from these?" Linn continued to ask.
Albert frowned slightly. "Is it possible that you are asking how many kinds of magic require the use of these two elements?"
"No, I mean their chemical formula, boiling point, density, application, specific heat capacity, critical temperature..." Lin En casually burst out a bunch of nouns, making everyone dizzy.
"For example, hydrogen, because its density is very low, when a large amount of hydrogen is filled into an object, it can make the object levitate." While Lin En spoke, he transformed a large amount of hydrogen with magic power, binding it to He surrounded himself, and his body soon slowly floated off the ground.
All the wizards present were shocked when they saw this. In other words, they might be able to use hydrogen elements to develop flying magic?
"Is the airship you made using hydrogen to levitate?" Albert immediately thought of this.
"No, hydrogen is a flammable substance. If used to make an airship, it will turn into a fireball in the sky if you are not careful!" Lin En shook his head. "So I used another element, which I will explain in detail later."
Immediately afterwards, Linn once again created a huge magic ball mixed with hydrogen and oxygen, and then launched it out of the window.
The magic ball broke open under a banyan tree, and a large amount of gas stored inside spewed out, followed by fireballs...
A violent explosion soon sounded in everyone's ears, and fire and flames shot up high. The poor banyan tree had been blown into two pieces. The surface of the tree was full of pits, and the ignited branches and leaves were scattered everywhere. The soft ground was also blasted with a huge hole.
The wizards in the classroom looked out the window one after another, and they were all stunned. This already had the destructive power of ordinary three-ring magic, and the process of casting the spell was not complicated. Even a one-ring wizard could easily do it.
"The optimal ratio of the hydrogen-oxidation chemical reaction is two to one. Then only a little flame is needed to trigger a violent explosion, and their product is water..." Lin En introduced calmly and calmly.
The wizards present quickly recorded this new combination of magic, and then they realized that this so-called chemistry class was about studying the nature of elements and the principles of magic to develop new types of magic.
Albert was flipping through the chemistry book in his hand, and was deeply shocked when he saw the explanations of various elements on the pages.
It seems that the [Arcane Society]'s understanding of the elements is far beyond their imagination. This is no longer detailed, but a clear study of all the characteristics of the elements.
What Albert didn't know was that Linn considered that the composition of the two worlds may not be the same and had not yet been confirmed experimentally, so he did not label the atomic weight, element period, electron configuration, atomic structure and other factors.
When Lin opened this chemistry course, he also wanted to ask these wizards to help him verify it. After all, it was too slow for him to study alone.
Just when Lin En was about to explain the other properties of elements, there was suddenly a rush of footsteps outside the door, and then the classroom door was opened.
Albert and others looked over displeasedly. They were immersed in the great thinking of exploring the nature of the elements, but their thoughts were interrupted by the sudden sound of the door opening.
Who is this blind person who dares to disturb them at this time?
It was Lydia who hurriedly rushed in. The halfling girl's face was filled with excitement and joy, and she shouted happily.
"Dean Lin En, the internal combustion engine... we have made the magic internal combustion engine!"
