Far away at Crescent Academy, Reiner was stretching.

Autumn was sleepy, and the cool weather was just right for a nap, causing Reiner, who had a regular schedule, to wake up more than half an hour late.

He had studied the latest Spellcaster's Handbook last night, which contained a brief introduction to the 10 most valuable spells of the year and the inventor's journey, and he believed that after this report, the exchange volume of these spells would continue to rise.

Reiner also likes two of them.

A flaming hand named Javier, the five-ring spell, requires 300 academic points, this spell is a super-enhanced version of the traditional flame burst, the inventor Javier mage has been studying the problem of burning efficiency for many years, and has made huge improvements to the original burning spell.

Javier's Burning Hand is capable of creating massive explosions, targeted blasts, and precision strikes within a radius of about one meter, and this spell can be used for mining ore, building roads, and demolishing projects.

Reiner's idea is to get the spell model and analyze it, extract the parts that enhance the power of the blast and control the location of the blast, and add it to his queen killer to make it more diverse.

The other spell is called Schmidt's Air Arrow, this elemental spell can create air arrows, enough to penetrate thin armor, depending on the user's needs, there are a variety of applications, because the air does not leave a trace, so it can be used in industries such as textiles, carving, etc., which are more demanding on appearance.

The reason why Reiner is interested in this spell is even simpler, although the Queen Killer is extremely weird, but Reiner must set up the bomb through personal contact or indirect contact, and spells such as Flame Explosion are too ostentatious, so the invisible air arrow is the best choice, and by setting the Queen Killer on the air arrow, it can maximize its unpredictable characteristics.

Originally, he didn't need to be in such a hurry to strengthen his combat ability, but after Olmster, Reiner once again realized that this was a magical world full of dangers, and the oncoming old man could be the killer of some evil organization, and if Reiner lacked the ability to protect himself, then it was easy to encounter unnecessary danger.

What's more, Reiner has now encountered the Serpent of Chaos many times and ruined their plans, and there are even people like Ampekos who have made a special trip to assassinate Reiner, he would be naïve not to improve himself.

Walking out of the room, Reiner made her way to the principal's office, where Elimia was sitting behind a desk on one side of the office working on papers, which was the exclusive place for the principal's secretary.

"You're late."

Arimia raised her eyes and looked at Reiner and said, her cheeks puffed out slightly, not knowing what she was angry about.

"Woke up a little late."

"As a principal, you have to set an example."

Bowing her head and continuing her work, Arymia spoke, ignoring Reiner.

"I see."

As soon as Reiner sat down, he saw the academic journals neatly laid out on the table, as well as the cooled black tea and bacon sandwiches, and he glanced at Elimia, the serious and old-fashioned secretary who was writing with his head down, not noticing Reiner's gaze.

"Elemia."

Taking a sip of the cooled black tea, Reiner called out Arymia's name.

"What's wrong?"

Raising her head, Arimia looked at Reiner with some confusion, and soon noticed the cup of black tea, her eyes a little wandering.

"It's nothing, I just suddenly wanted to say thank you to you."

Reiner smiled, his gaze causing Arimia to look away with some embarrassment, not knowing what he was muttering.

Shift your attention to the journal in front of you.

This is the latest issue of the journal that is regularly purchased, and Reiner had a habit of picking up "Alchemy", but the cover of "Truth" aroused his curiosity.

In the previous issue of Truth of Truth, which used Reiner's model of the atomic nucleus structure as the cover, Reiner also saw a paper on the aether drift experiment, which was a huge blow to the proponents of the wave theory of light, which meant that they either abandoned the theory of electromagnetic wave propagation based on the ether, or they had to abandon the more basic theory of the planet revolving around the sun, and the aether drift was like a dark cloud hanging over the heads of all mages.

Reiner is also curious about the Aether Theory, after all, there is magic in this world, what is the essence of magic, and how magic is conducted, these cannot be answered with the original knowledge on the earth, so Reiner is very concerned about the research of this area, but it is a pity that except for some high-level mages, other mages are really difficult to continue the research of magic, this power they are most familiar with, but it is the most mysterious.

On the cover of this issue of "Truth", there is a huge black ellipsoid, in which there is a faint red light, which is spreading outward.

Reiner flipped through the table of contents and quickly found the paper on the cover.

"On the Theory of the Law of Energy Distribution in Normal Spectrum", by Ludwig. Stein, the High Mage of the Eight Rings.

Turning to this page, Reiner quickly saw the object of the paper's research, blackbody radiation.

"I didn't expect that the dark clouds drifting in the ether had just appeared, and the dark clouds radiating from the black body had already been dispersed."

Reiner smiled and muttered to himself, continuing to read the paper.

The content of the paper is somewhat messy, but the thinking expressed is shocking, and the assumption that the energy of the vibrational system cannot change continuously, but jumps from one energy particle to another in a discontinuous form, and this hypothesis has perfectly solved the problem of blackbody radiation that has plagued the mages for many years.

The proof process of the paper is rigorous and self-consistent, and if a direct proof of quantum existence can be found, then this paper must be enough for Stein to touch the threshold of legend!

But to be honest, the ideas contained in this paper are so advanced that even His Excellency Stein himself wrote at the end of the paper that the paper came from a fleeting inspiration, based on a hypothesis that could not be verified for the time being, and that even he himself could not guarantee that it was correct.

Later in the paper, the comments of several high-ranking mages also point this out.

"Although the energy discontinuity theory can explain the spectral problem of blackbody radiation well, after all, this is a hypothesis made to fit the experimental data, and it cannot be judged whether it is applicable in other aspects. - Pluto. Alterac.

"Wonderful, I can only use such words to describe my feelings about this paper, the theory of energy discontinuity breaks the shackles of the past and provides a new interpretation of the world, but unfortunately the paper only discusses the problem of blackbody radiation, if it can be extended to other fields and verified, then this theory will definitely be one of the greatest theories of the last decade." - Eagles. Field.

"The energy discontinuity theory is a new system, which is very different from the existing classical magic system, and we must be cautious about this theory, because this theory has involved the foundation of magic, although the energy discontinuity theory perfectly solves the problem of blackbody radiation, but its applicability in other aspects still needs a lot of verification." - Broly. Augustine.

After reading these reviews, Reiner thought to himself that it was indeed another thing.

It's time to prepare the experimental materials and verify the photoelectric effect, he thought.
