In the evening, in the city of kerosene, inside the wizard academy.

Philip was speaking at the podium, explaining the seventh element on the periodic table - nitrogen - to the apprentices and formal wizards below!

As the most abundant element in the atmosphere and one of the first elements that all apprentices come into contact with, it has not been taken seriously by wizards in the past.

After all, it is difficult for this thing to produce magical reactions with other common elements, and it is even considered a useless element by many schools of thought.

However, this is obviously just because some people's research on nitrogen is not in-depth enough.

For example, in Master Lin En’s [Research and Analysis on Plant Photosynthesis], it is mentioned that nitrogen is one of the essential nutrients for plant growth.

Rumor has it that the cardinals of the church have mastered a special divine art - natural rain, which can greatly increase grain production. Its principle is probably to use nitrogen as fertilizer. The effect is more than 60% higher than the yield-increasing magic developed by some elemental schools!

This is enough to show that the church has surpassed them in the knowledge and application of nitrogen, and now is the time to catch up! "But, Professor Philip, didn't Master Lin En develop a way to make bread with magic? Why do we still need to develop this kind of magic to increase crop yields?" A student asked curiously.

"Magic bread is true, of course, but we can't always eat bread, right? We need to change our taste..." Philip replied with a smile.

The magic of increasing yield using nitrogen is not only effective for wheat. In theory, it is applicable to any kind of plant and is also effective for some potion ingredients.

In addition, the property of nitrogen that it is not easy to produce magical reactions with other elements can also be used in reverse, and it can be used as a protective and filling element. For example, the magic lamps used to light up the night sky throughout the kerosene city contain a large amount of nitrogen.

As Philip continued to talk, the melodious sound of the magic bell rang quietly.

"Okay, let's end today's chemistry class here. The properties and applications of nitrogen is a topic that is worthy of study. Next week, everyone will need to submit a paper to explain your understanding of this element... Whoever can develop a new technique here will be rewarded with 100 credits..." Professor Philip said with lingering feelings.

The wizards below were all very excited.

Credits are a new system within the Wizarding Academy, which is assessed based on class performance, essay evaluation, and magic assessments, and is related to their future work arrangements when they leave the Wizarding Academy.

If one can obtain more than one thousand credits within one school year, he or she will be able to obtain recommendations from professors, enter the Academy of Magic after graduation, and even gain the appreciation of great wizards and become a core member of the parliament.

The fastest way to earn credits is naturally to develop new magic or come up with novel magic theories.

For example, Ryan, the most dazzling magic genius in the Wizarding Academy, obtained more than 600 credits in just over two months by relying on three papers explaining the movement of celestial bodies!

It is said that these three papers directly alarmed several congressmen. If nothing unexpected happens, joining the Academy of Magic is a foregone conclusion!

This naturally made all the wizards envious. You know, the members of the Magic Academy are all specialized in the most advanced magic theories, which is the paradise of all academic wizards! Philip, who teaches elemental science, once mentioned to them that the periodic table distributed by the academy is actually incomplete, with only more than 50 elements on it. The real periodic table has twice as many elements! In addition to metal and non-metal elements, there is also a new type of element named by Master Lin En, but only the parliamentarians and elemental wizards in the Magic Academy know it.

The students left the classroom while chatting with each other. Ryan, a recognized magic genius, was highly praised by many people. Everyone could see that he had a promising future and might be the next magic star! "Do you have any idea about the research paper on nitrogen, Ryan?" a tall and thin wizard asked with a headache.

This element is not very suitable for casting magic. If one focuses on increasing plant yields as Philip mentioned, it would be almost impossible to stand out and get high scores.

After all, someone had already tried this and had a relatively complete magic theory. It would be difficult for their research to go beyond this system in just one week.

No wizard would be willing to see his hard work and research become obscurity in the end!

If there is anyone who has the ability to blaze a new trail, it would naturally be Ryan, the magical genius!

Facing the expectant gazes of the crowd, Ryan smiled. "I guess so. I already have some ideas and am thinking of a magic involving nitrogen."

"So fast?" The wizards present were all astonished. They were still considering which direction to start their research, but Ryan had already begun developing new magic.

"In fact, the Magic Star has already pointed out the specific direction. At best, I have only expanded upon Master Lin's research." Ryan said modestly, but a look of complacency was evident on his face.

"You are worthy of being called such a genius. If you continue like this, you will be able to leave this academy and join the Institute of Magic in two months at most." The wizard said with great envy.

The other wizards also praised him continuously, and at the same time, they also asked him indirectly about the new magic that Ryan was going to develop.

Facing the flattery and praise from the crowd, Ryan had a constant smile on his face, but he didn't show any intention of revealing it. After arriving at the trainees' residence, he spoke apologetically.

"I have an appointment with other people today, so please go back first."

The supporters who failed to get any clues could only leave in disappointment. They planned to read the paper on plant photosynthesis carefully several times after returning, perhaps they could find some new ideas.

As for Ryan's whereabouts, many people know it well. This magic genius has recently fallen in love with a good-looking witch, even to the point of obsession.

But this is human nature, and naturally no one would spoil the fun and disturb the interest of this magical genius.

After bidding farewell to his admirers, Ryan straightened his robe, walked into the school's residence with a smile on his face, and gently knocked on the door of a house.

About three seconds later, the door opened spontaneously, and a clear voice was heard.

"Come in!"

The smile on Ryan's face grew wider, and he stepped into the house with a hint of excitement. Everything he saw was somewhat beyond his expectations. This place was not as beautiful as he had imagined, but instead looked like a large magic laboratory.

There are all kinds of strange alchemical instruments everywhere.

The most eye-catching thing was the iron ball hanging in the middle of the living room that was swinging in a continuous circle. Just as he entered the door, a wooden sign with scales marked on it was knocked to the ground, making a slight "click" sound.

In addition, Ryan saw the mirror and torsion balance placed on the experimental table, as well as several spheres of different sizes that were constantly rotating under the drive of magic.

"Is this Master Lin En's pendulum and mirror reflection experiment? And the celestial body movement model?" Ryan recognized it immediately, and then said with a smile. "I remember that the wizard academy's display room has these things, right? Cynthia?"

In order to allow new students to admire the greatness of magic and to facilitate daily teaching, every wizard academy in the kingdom has a complete experimental model in its showroom.

Every wizard who enters the showroom for the first time will unanimously marvel at the ingenuity of the magic star's conception, who was able to come up with such a simple method to demonstrate the extremely complex issues of gravity and celestial bodies.

Therefore, if you want to study relevant theoretical experiments, going to the exhibition room is undoubtedly the best choice, and you can also listen to the professors explain the detailed process of the experiment in detail.

"But I prefer to verify this process myself..." The girl named Cynthia said casually. She didn't even turn around to look at Ryan who came in, but focused her attention on the experimental table in front of her. Her slender fingers were holding a strange creature that looked like a cube.

The girl's words made Ryan pause for a moment, and then he quickly changed the subject and said, "You are right. No matter how much you listen to others' explanations, it is better to try it yourself."

"Also, it's a pity that you missed today's element class. Nitrogen has a wide range of applications and is not a useless element. It plays an extremely important role in shaping and biology..."

Ryan knew that the girl in front of him was very interested in magic, so he recounted in great detail what Philip had said in class today, and especially mentioned that the professor of elemental studies would reward the student who developed a new magic with 100 credits.

"I just happened to have an idea to use nitrogen, and I'm planning to use it to develop a new magic!" Ryan said proudly, like a thunderbird showing off its feathers to attract a mate.

"Oh?" Cynthia finally stopped what she was doing and turned to look at Ryan with interest. Her violet eyes seemed to be able to touch people's hearts.

Ryan wanted to keep the question a secret, but under the girl's expectant gaze, he couldn't help but speak. "I think since nitrogen doesn't react easily with other elements, it can be used to preserve food and weapons. The Parliament filled the magic lamp with this element in order to increase the life of the filament..."

Ryan spoke of his idea very confidently. He had read a paper on the application of vacuum before. It mentioned that one of the characteristics of vacuum is that it can allow food or utensils to exist for a long time.

For example, a purple fruit can be kept in a vacuum state for several months without rotting!

However, maintaining a vacuum field requires a large amount of magic power, and only great wizards can do it. Ryan believes that nitrogen can be used to replace the role of the vacuum.

The effect is not that good, but it can greatly reduce consumption. As long as you are a formal wizard, you can do it easily! "That's a very good idea!" Cynthia nodded with a smile.

Although it was just a simple compliment, it made Ryan feel a surge of blood rushing from his feet to his heart. He spoke in a daze. "When I finish writing this paper, you can submit it. It will definitely be appreciated by the professor..."

As soon as he said this, Ryan regretted it. This was an idea he had come up with with great difficulty.

Fortunately, the next moment, he heard the girl speak softly.

"No, that's your idea after all."

Ryan's heart suddenly relaxed, and then he reflected in annoyance on why he felt that Cynthia was a shameless person who would plagiarize other people's work.

After refusing, Cynthia spoke again casually.

"I heard that your thesis was appreciated by a great wizard. He is a core member of the council and is planning to accept you as his disciple. Is that true?"

"It's just luck. If you hadn't reminded me and inspired me, I wouldn't have been able to complete three papers on the movement of celestial bodies so smoothly." Ryan said modestly, trying to bring the two closer.

"If you want to thank me, now's a good chance." Cynthia said softly. Her voice was very pleasant, with a hint of laziness, but full of infinite temptation.

"What opportunity?" Ryan patted his chest and said, "If you are in any trouble, I will be happy to help you!"

"I have a research project that requires the help of a great wizard, and I would like to ask you to introduce him to me." Cynthia said casually.

"Of course no problem!" Ryan agreed without hesitation. The master admired him very much and would not refuse such a small request.

Ryan had some little ideas in his mind, which was to join that adult's school with Cynthia, so that the two sides would have more opportunities to contact each other.

"Thank you very much, Ryan." Cynthia smiled softly, and then changed the subject. "Unfortunately, I have some things to deal with for the time being, so I'll leave my thanks to next time."

Ryan was so excited that he wondered what form this thank you would take. He was very gentlemanly and didn't argue any further. He just left the room in a daze.

The door closed automatically, and Cynthia continued to focus on the cube in front of the laboratory table, scratching alchemical runes on one of its sides with a carving knife.

The room was very quiet, with only the sound of wind caused by the swinging pendulum.

She had already forgotten the last time she had studied and made alchemical creations so seriously in the laboratory...

That must have been a long, long time ago.

Cynthia's face showed a look of nostalgia, but the next moment, as if she sensed something, she suddenly turned her head to look out the window and whispered softly.

"What a powerful energy fluctuation!"

It looks like the Wizarding Council has come up with some new weapons.

As Cynthia thought about it, she waved the carving knife in her hand and drew the last rune...

The cube in his hand immediately floated up, and the alchemical runes engraved on it seemed to be alive, constantly rotating and jumping.

It seems that her skills are not rusty at all, Cynthia nodded with satisfaction.

Then it's time to move...
