Bang, the door was slammed open.

"Boy, what did you just say?" Mage Linyana held her staff, the tip of which was pointed straight at Leo's chest, her hairs standing on end at Leo's words.

Kicking and kicking, two steps back, Leo was secretly shocked by the strength of the other party, and he saluted respectfully: "My lord, Leo's research has made a major discovery, a major discovery on the use of lightning energy. ”

Mage Linyana herself is a pure thunder mage, and when she heard this, she said with a look of surprise on her face, "Are you sure?"

"Sure. Experiments will prove everything I say. Leo's calm face was full of absolute confidence.

"Okay, come in quickly, and let the old woman see what kind of experiment you have done to dare to say such a thing. The wrinkles on Venerable Linyana's face glowed, and her eyes were full of anticipation.

Leo walked into the cubicle, sat down at the table and began to fetch something, a finger-long black stone, a finger-long round iron rod, a copper wire wrapped in insulation, a piece of plastic, and some fine scraps of paper and small pieces of iron.

Master Linyana sat across from him, watching Leo separate a few things and asking, "Leo, this is the Repulsion Stone, I know this thing can attract iron pieces, but he doesn't seem to have any other use for it." ”

To put it bluntly, the repulsion stone is a magnet, and Leo took the one-finger-long magnet and said: "My lord, the repulsion stone can attract iron pieces, indicating that it exists in some special force, which is called gravity. ”

Linyana nodded in agreement with Leo, and she watched curiously as Leo picked up the plastic piece, first sparing the scrap of paper without any reaction, then rubbing it against her hair, and a moment later Leo dangled the plastic piece in the air again.

Something miraculous happened, the confetti seemed to be suspended, and one by one flew up out of thin air, moving closer to the plastic block, and in a moment it was already possessed by it.

"This, this, what's going on?" Master Linyana didn't believe in evil, snatched the plastic block from Leo's hand and examined it, and finally she broke it into several knots.

"Force, gravity, this is also a gravitational force, a gravitational force that a person can make. Leo said.

"Gravity?Is it the same as the Repulsion Stone?can it be done with a few simple rubs?" Master Linyana didn't know why, and her already striated face was even more profound at this time.

Ignoring Master Linyana's confusion, Leo first wrote 'N, S' marks on both ends of the repulsion stone, and said in his puzzled gaze: "My lord, this repulsion stone is a whole, so its structure and nature should be the same. If there are two repulsion stones, we can see the repulsion phenomenon, but if I divide it into two now, will there be a repulsion phenomenon?"

Smack, the repulsion stone broke off in response.

Venerable Linyana didn't know why, but she still said according to her own understanding: "I know what you said, there is a gravitational and repulsive force between the two repulsion stones, which is also the origin of the name of this stone. But there is a property of the repulsor, that is, a whole is divided, and no matter how many parts are divided, they are the characteristics of the specific and complete repulsor. ”

Leo was stunned for a moment, the information only briefly introduced the repulsion stone, he thought that these people didn't know, and now it seems that it is a superfluous move.

"My lord, it's time to witness the miracle. Leo spoke in a serious tone and looked serious, and carefully began to wrap the copper wire around the small iron rod.

What does it mean? Miracle?

Mage Linyana watched with a question mark as Leo methodically fiddled with the small iron rod and copper wire, which was finally attached to a piece of material with an electric rune attached.

What is this for? What are so many coils of copper wire wrapped around the iron rod? Could it be that too much lightning will be transmitted through the insulation outside?

"Miracle, miracle, it's really a miracle. How is this possible, how is it possible, how is it possible!" Master Linyana let out a sharp voice that was extremely inappropriate for her age, and she quickly snatched the object from Leo's hand and began to experiment on her own.

"There is nothing that cannot be done, only the unexpected, miracles are everywhere. Leo watched Master Linyana go about his steps, and he said, "My lord, how is this experiment? ”

As Master Linyana spoke, he swung the battery iron intently, and Leo said, "My lord, I have been studying the two phenomena just now for a long time, and I suspect that there is some unknown basic unit rune in it.

I didn't find this kind of rune in the repulsion stone, all I have been searching for the repulsion and gravity to be generated, until I have undoubtedly found these two cases, all of which I suspect must be unknown runes.

If we can find this kind of rune, then can we also create spells that have the same ability of gravity and repulsion?"

Leo was talking about his research, and he found that there was no law of electromagnetic induction in this world, but some small magnetic induction experiments did, so he suspected that there should be a basic unit rune similar to the electric storage rune.

The words were amazing, Leo had no idea how much his words had shaken Master Linyana, and the discovery and creation of new runes would be left on the Academy's Wall of Honor.

"Say, boy, tell me everything you have researched, you can say what you want to say, and the old body will also do it for you, but you must not use false information to fool the old body. "Master Linyana looked like she was going to eat Leo alive.

"My lord, you have helped me for more than ten years, Leo has taken it to heart, I don't want much things, a model and knowledge of a first-level spell, a model of transfiguration and some materials. Leo said seriously.

Master Linyana was stunned for a moment, some didn't know if what Leo said was true or false, the last time the knowledge about gases was the other party asked for the reading permission of the entire library, and now this knowledge is more important in her eyes than the last time, just some materials and models?

"Boy, don't fool me, the old body knows your kid's virtue. ”

Leo said: "My lord, this is the list of materials I need, if you are not at ease, we can sign a contract." ”

"Wait, what you just mean is that we don't need to sign a contract for this knowledge, I can take it out and study it with others, or even put it in the academy's library?"

"Absolutely. ”

"Why?"

"Why, huh. Leo laughed at himself: "Because I'm leaving here, leaving the coast of the East Continent and going back to the West Continent, these things are just for me to repay the relationship between you and the academy." ”

"You, you, you, ....... Master Linyana sighed and fell silent, she knew better than anyone why Leo left here, after so many years of contact, she found that this kid was all about research, and there was no cruel, cold, and ruthless side of wizards at all.

The thing that Leo told Linyana was simple, electromagnets were all available in the elementary school curriculum, and the truly revolutionary and epoch-making thing was that three-sided wheel in his storage bag.

It was something he had spent a long time simulating stator windings and the like, and it was the key to converting electrical energy into mechanical energy, but it was useless, and he guessed that it was probably because the object was too big and there was no such thing as magnetic induction.

Master Linyana took the list handed by Leo, and after reading it, she said, "This material is the material for refining the De Xinnuo Liquid and the Detergent Elixir, can't you break through the first-level mage and you want to wash off the rune mark and become an ordinary person again?"

Leo was silent, and let the other party guess with his actions.

"Hey, you wait for me here, although some things are rare, the old body can still get them. Master Linyana sighed and turned to walk out.

Gen Linyana is a true research-obsessed mage, and her strong background allows her to focus on what she loves without having to think about it so much.

Leo has a lot of help from the other party, he doesn't want to owe others a favor, the electromagnet is just a way to use electricity, and the other party is a lightning mage, he is really just doing this to repay the favor, he doesn't want to owe others anything.

Mage Linyana is as vigorous as her spell system, and she brought back what Leo needed in an hourglass time, and when the two said goodbye, Mage Linyana handed Leo something and said: "You can take this 'Desande's gift' and save your life at a critical time, I still hope that you will come back after becoming a first-class mage." ”

The thing was a necklace, the black iron color was very inconspicuous, Leo didn't know whether he didn't want to accept the other party's favor anymore or was worried that it would be manipulated, he rejected Master Linyana's kindness, put the materials and three crystal balls into the storage bag and said goodbye to the other party, and walked towards the academy management center.
