Evening, in the City of Oil, inside the Wizarding Academy.

Philip was talking from the podium, explaining to his apprentices and official wizards the seventh element on the periodic table, nitrogen!

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 has a hard time magically reacting with other common elements, and is even considered a useless element by many schools.

However, this is obviously just a fact that some people have not studied nitrogen deeply enough.

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

It is rumored that the cardinals of the Church have mastered a special magic - natural rain, which can greatly increase the yield of food, and the principle is mostly that nitrogen can be used as fertilizer, and the effect is more than sixty percent higher than the yield increase magic developed by some elemental schools!

This is enough to show that the church has surpassed them in the knowledge and use of nitrogen by a lot, and now is the time to catch up!

"But, Professor Philip, didn't Master Lynn develop the means to make bread by magic? Why do we need to develop this magic to increase crop yields? One of the students asked curiously.

"Magic bread is true, but we can't always eat bread, can we? A change of taste...... in general," Philip replied with a smile.

Using the magic of nitrogen to increase the yield, it is not only effective for wheat, but also theoretically applicable to any kind of plant, and it is also effective for some potion ingredients.

In addition, nitrogen's ability to not easily react with other elements can also be used as a protective and filling element, such as the magic lamps used to light up the night sky throughout the city of fire and oil, which contain a lot of nitrogen.

As Philip continued to speak, the melodious magic bell rang quietly.

"Okay, that's all for today's chemistry class, the properties of nitrogen and how to use it is a very interesting topic, and next week, everyone will need to submit a paper on your understanding of this element...... Whoever can develop a new spell here, then I will give him a reward of 100 credits......" Professor Philip said with a sigh of relief.

The wizards below were thrilled.

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

If you can get more than 1,000 credits in one academic year, you can get the recommendation of professors, enter the magic research institute after graduation, and even gain the appreciation of the great wizards, and become a core member of the council.

The quickest way to earn credits is to develop new magic, or to come up with novel theories of magic.

For example, Ryan, the most dazzling magical genius in the Wizarding Academy, got more than 600 credits in just over two months with three papers on the movement of celestial bodies!

It is said that these three papers directly alarmed several councillors, and if nothing else, joining the Academy of Magic is already a sure thing!

This is naturally the envy of many wizards, you must know that the members of the Magic Research Institute specialize in the most cutting-edge magic theories today, and it is a paradise for all academic wizards!

Philip, who teaches elementology, once mentioned to them that the periodic table distributed by the academy is actually incomplete, there are only more than 50 elements on it, and the real periodic table is twice as much!

In addition to metal and non-metal elements, there is a new elemental type named after Master Lynn, but only known to the Councillors and elemental wizards in the Magic Academy.

A group of students talked to each other and left the classroom, and Ryan, who was recognized as a magical genius, was even more popular with many people, and everyone could see that the other party had a bright future, maybe it was the next magic star!

"Do you have a clue about a research paper on nitrogen? Ryan? A tall, thin wizard asked, with a headache.

This element is not very suitable for magic, and if you work on the increase in plant production that Philip said, it is almost impossible to stand out and get a high score.

After all, someone has already tried this, and they have a relatively complete theory of magic, and it is difficult for their research to go beyond this system in just one week.

No wizard would be willing to do his hard work and end up in the dark!

If you have the ability to find a new path, it is naturally Ryan, who is a magical genius!

Facing everyone's expectant gaze, Ryan smiled. "Well, I've got a bit of a clue and I'm coming up with a magic for nitrogen."

"So fast?" The wizards present were stunned, they were still thinking about which direction to start researching, and Ryan had already begun to develop new magic.

"Actually, the specific direction has already been pointed out by the magic star, and I am at best just expanding on the basis of Master Lynn's research." Ryan spoke humbly, but the smug color was on his face.

"It's really you, if you continue like this, you can leave this academy in two months at most and join the Academy of Magic." The wizard said with envy.

The rest of the wizards were also complimenting, and at the same time, they were also asking about the new magic that Ryan was going to develop.

In the face of everyone's sycophants and praise, the smile on Ryan's face never stopped, but he didn't reveal it at all, and after arriving at the student's station, he said apologetically.

"I also have an appointment with someone else today, so please go back first."

The supporters who couldn't ask any clues could only leave in a huff, planning to go back and read the paper on plant photosynthesis a few more times, maybe they could find some new ideas.

As for Ryan's whereabouts, many people know that this magical genius has recently fallen in love with a good-looking witch, and has even reached the point of obsession.

However, this is also human nature, and naturally no one will disturb the interest of this magical genius.

After bidding farewell to the group of suitors, Ryan straightened his robes, entered the school's residence with a smile on his face, and gently knocked on the door of a certain house.

About three seconds later, the door opened spontaneously, and a clear voice rang out.

"Come in!"

Ryan had a smile on his face even more, and he stepped into the room with a hint of excitement, and what caught his eyes was somewhat unexpected, it was not as beautiful as he had imagined, but like a large magic laboratory.

Everywhere there are all kinds of strange alchemy instruments.

The most conspicuous thing was the iron ball hanging in the center of the living room, which was constantly swinging in a loop, and the moment he entered the door, a wooden sign marked with a scale just happened to be knocked to the ground, making a soft 'click' sound.

In addition to this, Ryan saw the mirrors and twisted scales placed on the lab table, as well as several balls of various sizes that were constantly circling under the influence of magic.

"Is this Master Lynn's pendulum and specular reflection experiments? And models of celestial movements? Ryan recognized it at once, and then said with a smile and a smile. I remember all these things in the showroom of the Wizarding Academy, right? Cynthia? ”

Placed in the room are very famous magic experiments.

In order to allow new students to appreciate the greatness of magic, and for the convenience of 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 invariably marvel at the ingenuity of the magic star's conception that he was able to come up with such a simple way to demonstrate the incomparably complex problems of gravity and celestial bodies.

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

"But I prefer to verify the process myself......" the girl named Cynthia said casually, not even turning her head to look at Ryan who entered the door, but focusing on the laboratory table in front of her, whose slender fingers were holding a strange creature that looked like a cube.

The girl's words made Ryan pause for a moment, and then hurriedly changed his words. "You're right, no matter how much you listen to others, it's better to try it yourself."

"In addition, it's a pity that you missed today's element class, nitrogen has a wide range of applications, it is not a useless element, and it plays an extremely important role in the field of shaping and biology......"

Ryan understood that the girl in front of him was very interested in magic, so he kept repeating what Philip had told in class today, especially mentioning that the professor of elementalism was going to give a reward of 100 credits to students who developed new spells.

"It just so happens that I have an idea to use nitrogen, and I'm planning to develop a new magic out of it!" Ryan said proudly, like a ptarmigan showing off his feathers for courtship.

"Oh?" Cynthia finally stopped what she was doing and turned her head to look at Ryan with interest, her violet eyes as if they could tug at the heartstrings.

Ryan wanted to sell Guanzi, but under the girl's expectant gaze, he couldn't help but speak. "I think that since nitrogen does not react easily with other elements, it may be useful for food and weapon preservation, and the council fills the magic lamp with this element in order to increase the life of the filament......"

Ryan spoke confidently about his idea, having read a paper on the use of vacuum, which mentioned that one of the properties of vacuum is that it can keep food or utensils alive for a long time.

For example, a purple fruit can be left in a vacuum for months without rotting!

However, it takes a lot of magic to maintain the vacuum, and only the Grand Wizard can do it, and Ryan thinks that nitrogen can be used to replace the vacuum.

The effect is not so good, but it can greatly reduce the consumption, as long as you are an official wizard, you can easily do it!

"Very good idea!" Cynthia smiled and nodded.

Although it was just a simple compliment, it made Ryan feel a rush of blood from the soles of his feet to his heart, and he said in a daze. "When I finish writing this paper, you can submit it, and I will definitely get the professor's appreciation......"

As soon as he said that, Ryan regretted it, it was an idea he had come up with with a hard time.

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 with chagrin as to why he thought Cynthia was a shameless person who would plagiarize the work of others.

Cynthia said again casually after refusing.

"I've heard that your paper has been appreciated by a great wizard who is a core member of the council and is preparing to take you as a disciple, is that correct?"

"It's just luck, if it weren't for your reminder that inspired me, I probably wouldn't have been able to complete the three papers on the movement of celestial bodies so smoothly." Ryan pretended to be humble, drawing the relationship between the two closer.

"If you want to be thankful, now is your chance." Cynthia whispered, her voice was very pleasant, with a faint lazy taste, but it was infinitely seductive.

"What chance?" Ryan hurriedly patted his chest. "If you get into any trouble, I'll be happy to help!"

"I have a research that needs the help of the Grand Wizard, and I would like you to introduce it to me." Cynthia said casually.

"Of course no problem!" Ryan agreed without hesitation, and the master admired him very much, and he should not refuse this small request.

Ryan still has some careful thoughts in his heart, that is, joining the adult's school with Cynthia, and then the opportunities for the two sides to contact will become more and more.

"Thank you then, Ryan." Cynthia chuckled softly, then changed her voice. "Unfortunately, I still have some things to deal with for the time being, so I'll save it for next time."

Lai An'an was in a reverie with a surging reverie about the form in which this thank you would be distributed, and he left the house in a trance.

The door was automatically closed, and Cynthia continued to focus on the cube in front of the experimental table, using her carving knife to draw the alchemy runes on one of the sides.

The room was quiet, except for the sound of the wind as the pendulum swayed.

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

That was a long, long time ago.

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

"What a powerful energy fluctuation!"

Looks like the Wizards' Council has come up with some new weapon.

Cynthia thought as she waved the carving knife in her hand and slashed the last rune......

The cube in his hand immediately levitated, and the alchemy runes engraved on it were as if they were alive, constantly rotating and beating.

It seems that her craft is not unfamiliar, and Cynthia nodded with satisfaction.

Then it's time to get moving......
