Donner's room doesn't have a magic lamp, but there is a workbench, paper, pen, and ruler, and even Donner borrowed a lot of special tools from Victor in advance for tonight.

The three oil lamps in the room were all placed on the workbench, which was not comparable to the extravagant magic lamp on Victor's Bench, but it was enough.

Donner carefully washed his hands before picking up the large fireball scroll he had just tricked from Victor and silently examining it. I have to admit that the scroll is indeed very precise, unknown animal leather, soft but tight, almost impossible to see the texture that ordinary leather should have, in a palm-sized space, hundreds of fire element magic elements are drawn, these elements are connected end to end, densely packed. Donner tried to find a pattern to their arrangement, but quickly gave up. Without sufficient knowledge, such an effort is doomed to be in vain, like finding patterns in the grains that are scattered haphazardly.

The other smaller scrolls, each drawing a fire element, look slightly different in style, obviously by a different person.

Putting down the scroll, Donner took out the transparent tracing paper he had prepared in advance, pressed it on the scroll and carefully traced a magic element, then moved it to the level of the workbench, and pierced the shape of the depicted element with the tip of a needle, and then found another element, traced it with drawing paper, and pierced it. At this time, Donner, like an experienced watchmaker, is making the most beautiful piece of his life, quiet and composed.

Each time he had to find a favorite element, and he became more and more picky, and by the time he finished sketching the thirtieth element, three hours had passed.

Downer then cut the drawing paper with the inscription to the size of a copper coin and threaded the thinnest needle through the holes he had carefully chosen. When he had done this, he straightened up and pointed the stack of papers against the oil lamp, rotating them one by one, and in doing so, his heart beat faster and faster, and his breathing became harder.

As more and more of the paper was folded, the transparent tracing paper became no longer transparent, but the light that came through the carved positions gradually formed a figure, and as the outline of the figure became clearer, Donner's forehead was already sweating.

His instincts were right! The strange feeling of the five magic elements was not because of the mystery of magic, but because they all resembled some kind of mathematical figure that Donner was familiar with, and in this world, Downer was the only one familiar with this kind of figure, and that was the sine function waveform diagram!

The fire element is a sinusoidal waveform!

For millions of years, this mischievous waveform hid behind that mysterious and rough flame totem, and it was not until this quiet night that the veil was lifted by the teenager in front of her, revealing her true face.

Donner tried to suppress the surging in his heart, piercing the thin needles one by one in the direction of the light, and then leaving the first and last two, pulling out the rest and covering them on the white paper, pointing out the needle holes with the tip of the pen, connecting them, and finally drawing a perfect waveform curve.

"Why is this waveform a fire elemental magic element? Why does it create a spirit element when it is painted with magic metal? A spirit element is also a form of a wave, and if so, what is the connection between the two?"

Donner had too many questions in his mind. But before those doubts are solved, he has more important things to do. What he has to do here is the most critical step to verify his guess.

He opened the leather box that Wesley had given him, took out the crystal bottle with the words "Flame Gold" written on it, opened it, pulled out the tracing pen engraved with the flame pattern, spread the tracing paper on the white paper just now, dipped it in the pen, and was silent for a moment, as if to accumulate strength, then took a deep breath and held it, and began to trace the perfect waveform curve.

"Just one!" he thought.

However, a magical force attracted him: "...... Come on, do it again, don't hesitate, don't be timid, do it again......"

So draw another one, another one...... It wasn't until the seventh one was painted and the flame gold in the crystal bottle was used up that Donner was distracted and came to his senses. Thinking of the danger he might face just now, Donner was inexplicably horrified, and cold sweat broke down his spine for a moment.

He threw away his pen and sat down in his chair, gasping for breath, closing his eyes, as if he could still see the figure he had just depicted, which rose and fell with his heartbeat, and then ...... Gradually it came to rest and became a dot, a bright red dot.

He opened his eyes, but the red dot was still there, no, not in his vision, but in his consciousness. The red dot moves with consciousness, flexible and free, suddenly fast, suddenly quiet.

Although he couldn't believe it, Donner still clearly knew that this was his first spiritual power element, this bright red fire elemental spiritual power element, it really and concretely appeared in his mind, but it was so incredible.

One year, a person who condenses spiritual power in a year, is considered to have a magical talent.

So, overnight, what about the seven strokes of condensing the spiritual power element?

Now, our genius is still slumped in his chair, but the panic in his heart has been replaced by joy: he is magically gifted, and more importantly, the veil of the goddess of magic has been lifted, and more unknown mysteries are waiting to be explored.

He knew that condensing his spiritual power so quickly must not be because of his talent, but because of that magical curve, compared to the totem-like rough fire element, it was so concise and perfect. Thinking of this, he immediately sat up straight and eliminated all traces on the table, leaving only the blank paper, which was carefully folded and placed in the most intimate pocket.

"If this secret were to be made public, then probably most ordinary people, if not everyone, would be able to practice magic, and the magic materials were so rare, it would inevitably cause a huge change, no, it would be a revolution, and no one knew if it would be a good thing for humanity or a catastrophe. Donner thought, of course, he also has other complex and subtle psychology such as sudden treasures, guilt, and so on. Either way, he decided to keep the secret and never reveal it.

Donner suddenly remembered the math problems he had discussed with Victor, but fortunately there were no trigonometric problems involved, but he still secretly decided that he could not continue to discuss math with Victor.

Also, one spiritual power element is obviously not enough, and it is necessary to continue to draw the element to increase the spiritual power, but the fire material is no longer available. The remaining four bottles of materials, if they are to be used for practice, also need to obtain the other four magic arrays from Victor.

Even if you are a genius, you need basic magic materials for practice, and you can't rely on Wesley all the time, so the next step must be to solve the problem of money. I don't know how the parts are being prepared on Merkel's side.
