"I miss it so much. It's been many years since I last came here." Albert said with emotion as he gazed at everything in the college that was familiar yet unfamiliar.
He never thought that one day he would step into this place again as a student and attend classes in the same academy with his son.
Although this feeling was a bit uncomfortable, Albert still came. It was not for the purpose of learning much knowledge, but he hoped to take this opportunity to establish some relationship with the talented Mr. Lin En.
There were many people who shared the same idea as Albert, so there were as many as two hundred official wizards returning to school this time, and there were countless wizard apprentices. Due to the large number of people and the only teacher, Lin En had to teach them in batches.
"Good afternoon, welcome back to school everyone. I am Lin En, the new president of Yieta College!" Lin En stood in front of the podium, looking at the wizards sitting in the classroom, and greeted them with a smile.
"It's an honor to meet you, Mr. Lin En." Albert stood up first and returned the greeting.
All the wizards present also stood up and saluted. This was not only because of the relationship between professor and student, but also because the other party was the leader of the Yieta School.
"Please sit down, everyone. You are all official wizards. I believe you all have unique insights into magic. I opened this course just to explain the elemental laws that I understand and summarize for everyone to discuss. I call it chemistry..."
Lin En did not act in a haughty manner just because of his status. He asked the goblins to distribute the textbooks while speaking.
Albert looked at the exquisite book cover in front of him curiously. The whole book was made of that special white paper. He reached out and opened the first page. On it was written the preface in vigorous handwriting: [Chemistry is a natural science that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels.]
"Dean Lin, what do these atoms and molecules mean?" a wizard asked with a bit of confusion.
"Atoms are the smallest particles that make up simple substances and compound molecules, which are what we often call elements." Lin En explained. "And molecules are made up of atoms, and are the smallest particles in chemical reactions..."
Lin En raised his hand, and a small ball of water quickly appeared in front of everyone. "For example, water is made up of many water molecules. The elements that make it up are hydrogen and oxygen... The chemical formula is H2O, also known as dihydrogen monoxide..."
"Aren't those [Ir] and [Fula]?" There was a slight discussion from the audience. This is the name given to the elements hydrogen and oxygen in the wizarding land. It is said that they were named after two wizards who discovered them in ancient times.
"How much do you know about hydrogen and oxygen?" Lin En asked again.
"【Il】, no, oxygen is the source of life. If an ordinary person who doesn't know magic is placed in an oxygen-free environment, he will die soon." Albert said thoughtfully.
For example, the third-ring magic [Life Forbidden Zone] creates an oxygen-free environment, causing the enemy to die in a painful struggle.
"These two elements can be used to release fire magic..." another wizard also added.
"Apart from these?" Lynn continued to ask.
Albert frowned slightly. "Are you asking how many kinds of magic require these two elements?"
"No, I mean their chemical formula, boiling point, density, application, specific heat capacity, critical temperature..." Lin En blurted out a long string of nouns, making everyone dizzy.
All the wizards present were excited when they saw this. This meant that perhaps they could use hydrogen to develop flying magic?
"The airship you made uses hydrogen to suspend it?" Albert thought of this immediately.
"No, hydrogen is a flammable substance. If it is 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. I will explain it in detail later."
Immediately afterwards, Lin En once again created a huge magic ball mixed with hydrogen and oxygen, and then fired it out of the window.
The magic ball broke open under a banyan tree, and a large amount of gas stored inside gushed out, followed by a fireball...
A loud explosion soon rang in everyone's ears, fire and flames shot up high, and the poor banyan tree had been blown into two pieces. The tree surface was bumpy, and the burning branches and leaves were scattered all over the ground. A huge hole was blown out of the soft ground.
The wizards in the classroom looked out the window one after another, all of them were astonished. This spell already had the destructive power of an ordinary third-ring magic, and the casting process was not complicated, even a first-ring wizard could do it easily.
"The optimal ratio of hydrogen oxygen chemical reaction is two to one. At that time, only a small spark is needed to cause a violent explosion, and the product is water..." Lin En introduced calmly.
The wizards present hurriedly recorded this new combination of magic, and then they realized that this so-called chemistry class was studying the nature of elements and the principles of magic, so as to develop new types of magic.
Albert was flipping through the chemistry book in his hand, looking at the descriptions of various elements on the pages, and was deeply shocked.
It seems that the [Mystical Society]'s understanding of the elements is far beyond their imagination. This is no longer just detailed, but a thorough study of all the characteristics of the elements.
What Albert didn't know was that Lin En took into account that the composition of the two worlds might not be the same and had not yet been confirmed by experiments, so he did not mark factors such as atomic weight, element period, electron configuration, and atomic structure.
The reason why Lin En opened this chemistry class was that he wanted to let these wizards help him verify things. After all, his research alone was too slow.
Just as Lin En was about to explain the other properties of the elements, there was a sudden sound of hurried footsteps outside the door, and then the door of the classroom was opened.
Albert and the others looked over with displeasure. They were immersed in the great thought of exploring the essence of elements, but their thoughts were interrupted by the sudden sound of the door opening.
Who on earth is so blind as to dare to disturb them at this time?
The person who rushed in was Lydia. The half-ling girl's face was filled with excitement and joy, and she shouted happily.
"Dean Lin, the internal combustion engine... We have already made the magic internal combustion engine!"
