Greetings, Mister Principal

Chapter 73: Making Fireball

Sharon stretched her body, put down her paintbrush, and looked at the mages she had painted by the table.

The second batch of Mage Cards had been delivered for printing. With the full production of several alchemy studios, Cola was spreading rapidly across the country centered on Prester. The daily income was already quite substantial, and the amount paid to Sharon as a reward for painting also gradually increased.

When she first sent the money home, her father thought Sharon was doing something illegal. After Sharon explained, and seeing Claire's letter, Sharon's father finally felt relieved.

Although he still had some criticisms about Sharon's indulging in painting, after seeing the paper with Sharon's name as co-author published in the "Monthly Alchemist Griffin", her stubborn father could not say anything.

"Don't you want to take a break?"

Roommate Evanna was sitting on the bed in cute pajamas. Since "The Lonely Wandering Gourmet" was serialized in "Daily Prester", she had given up the habit of reading newspapers before going to bed and instead changed the reading time to dinner. It more or less eased the torture of the food description on her stomach.

"Mhm, I'll go to bed right away."

Sharon nodded and looked at the painting she had just finished.

The number forty-seventh mage card was painted with an old mage. He was holding a compass and measuring something on the ground. Behind him, a spiral was extending, and along the spiral, there were countless mathematical formulas.

This was the mage Demira Collins from one thousand six hundred years ago. He was known as one of the originators of mathematics. Many of the mathematical formulas that people used today were discovered by this mage.

He was quite accomplished in law and element studies. Demira proved that the buoyancy of an object in a liquid was equal to the weight of the liquid it displaced. This principle was called Demira's principle and had been passed down to this day.

Demira also discovered the Demira spiral in geometry, and based on this, he created sixteen spells that were still used by people today.

But the fall of this mage was very regrettable. He was defeated in the battle of the ancient mages, imprisoned by a hostile mage, and eventually assassinated in prison.

But even in prison, Demira was still immersed in research. It was said that he was still studying geometry before being killed. When the assassin stepped into the prison and prepared to kill Demira who was sealed with magic power, he was not scared. He just sternly reprimanded, "you broke the circle I drew!" Then he was killed.

Sharon sighed softly, then packed her drawing tools and changed into her pajamas.

Recent life had been much busier and fulfilling compared to the past. In addition to painting, Sharon focused on studying the alchemy books that Reiner gave her.

Perhaps in time, Sharon could also become a qualified alchemist.

Sharon remembered the note she wrote about her future thoughts in the past. She clearly remembered what she wrote on that piece of paper: I hope to be able to depict the colors of this world.

And now, she was on the road to her dream.

Sharon looked out the window. The crescent moon was like a hook, it was quiet and peaceful like this academy.

......

In Reiner's room, the magic power was like light smoke, lingering beside him.

This principal's consciousness at this time was floating in his Heart Lake.

In the sky, the hot sun was dazzling, shining on the earth, while the quiet lake reflected the sunlight, giving out blurred light.

On the side of the lake, a huge flame was burning, shining with the sun.

This was a secluded world, Reiner's consciousness was standing in the air, and now, he wanted to leave a mark on this world.

He waved his hand gently, and a silver track was drawn. It was a straight line, dividing the world into two.

Then, Reiner's fingers wandered in the air, and the beautiful and complex curves gradually formed.

Between the intricate trajectories, light sparkled.

The scorching sun in the sky gradually dimmed, as if night was coming.

In the faint sky, corresponding to the sparkling light in front of Reiner, countless bright stars were shining.

One light dot, two light dots, three light dots, the stars around Reiner gradually lit up, and streams of light burst from the stars, and followed the countless silver trajectory, quickly covering Reiner.

At the same time, the lake water rippled.

The rippling and the surging lake formed a subtle unity with the bright stars beside Reiner.

When the last trajectory was also filled, the entire spell model began to burst out with a flash of dazzling silver brilliance, and then immediately shrank and sank into Reiner's body.

Reiner's consciousness stretched out his hand, and a fist-sized fireball gathered in his palm.

Different from the bright yellow flames of ordinary mages, the fireball in Reiner's palm was light blue. Obviously, this was because he had constructed the fireball technique that used hydrogen as the basic fuel.

"This is, mass-energy conversion?"

Reiner felt an indescribable force condensing burning hydrogen and oxygen in his palm. Before he could feel it carefully, the flame became more and more fierce, and the heat could not be restrained by magic, it blew the scorching wind toward his face.

He threw the ball of fire.

The blue bright flame flew across the sky like a shooting star and fell on the rock wall by the lake.

Boom!

A loud noise rang out, the solid rock disintegrated in an instant, and the high temperature melted the rock near the core of the landing point, forming a glass-like quartz crystal. As for the outer rock wall, it was shaken and broken by the huge shock wave of the explosion; smoke spread out in a ripple shape.

"If it is really the conversion of mass and energy, then it seems that many things can be explained."

Reiner muttered to himself as he watched the crater made by his fireball.

But now apart from a classic formula, he did not have any understanding of the conversion of mass and energy, nor did he know whether it conformed to this world, so he could not generate any feedback.

He didn't dare to build cognition with this, for fear that problems would cause his cognitive collapse.

"It seems that this can be the future research directions."

Thinking in this way, Reiner couldn't help thinking of the picture of himself standing on the ground, casting the hydrogen bomb with his hands.

This made him a little excited.

"It's better to set this thing aside first."

Reiner looked at the sky that was gradually returning to normal. Among the shining stars, it was obvious that the magic model of fireball had formed a constellation, shining between the galaxies.

"It seems that I have succeeded."

The whole process went smoothly unexpectedly. Moreover, the explosive power of the fireball technique composed of hydrogen burning was far greater than that of the ordinary fireball technique. As long as the magic power supported it, Reiner could continue to throw the fireball out. He had at least one means of self-protection now.

Reiner's consciousness returned to reality. He opened his eyes, and before he could feel the magic engraved in his soul, he saw a pair of eyes staring straight at him
