Wizard: I brought the wrong system.

Chapter 102 Refraction

After searching through the library for a long time, Yaro discovered that the books on Bosco's list were not available on the floors of the library he could access.

……

At the library's front desk, the female apprentice explained with a smile, "Without making sufficient contributions to the academy, no matter how many magic stones you spend, the academy will not grant you higher knowledge access."

Yaro doesn't have time to slowly accumulate contribution points and upgrade library privileges. Right now, he needs to be fast, the faster he is, the more attention he can attract from Wizard Bosco!
"I understand, then I'll rent these two books."

The two books are titled "A Shortcut to Angle Calculation" and "An Analysis of Basic Light Magic," respectively, both titles written by the wizard Bosco later.

The knowledge written in "A Shortcut to Angle Calculation" was at most at the junior high school level in his previous life. After flipping through it once, Yaro had already recalled the knowledge he had learned before.

He rented the book again partly to reinforce his memories, but more importantly, to correct his problem-solving habits.

The method recorded in this book may not be faster than his previous life's calculation method, but Yaro is unwilling to reveal his knowledge of his previous life, so it is necessary to consult this book and practice a few questions using the methods recorded in it in order to answer any possible questions from the wizard Bosco.

However, the focus of Yaro's research is "Analysis of Basic Light Magic".

Firstly, because Aro himself possesses a fire-based magical source, and fire is inherently closely related to light. For example, Aro's 'Light Magic' is a prime example of using fire magic to exert the effects of light.

Studying this book carefully may be helpful for Yarrow's future development.

Another reason is that Yaro is very curious about the power of light magic.

Everyone knows that the speed of light is the fastest speed in the material world. If the power of light magic is also considerable, wouldn't a wizard who specializes in light magic be invincible?

Why have I never seen a wizard who majors in the light element?
Where does the problem lie?
Back in Emerald Plains, noticing that the door to the cabin was closed from the inside, Yaro knew that his senior had returned. He didn't knock on the door, but instead found two pieces of wood nearby to sit down and opened "Analysis of Basic Light Magic".

The first part of the book, "Analysis of Basic Light Magic," mainly explains some difficulties in learning basic light magic. However, the second half of the book explains many of the basic principles of light magic. In it, Yaro finally understands why the power of light magic is weak.

A wizard's mental power cannot keep up with light magic!

In addition, for some inexplicable reason, it is difficult for spiritual energy to attach to light, causing light-based spells to simply release light!
Just like the major categories of wizards, such as shadow wizards, there are also many conceptual classifications of light wizards.

For example, the light of healing, the light of purification, the light of destruction, and so on.

Just like the Shadow Wizard, all his abilities come from the Shadow Realm.

These categories of light-based abilities also require the assistance of different otherworldly realms or extraordinary beings, but once any ability is used too many times, its ultimate fate is inevitably to be integrated into them.

The author of this book treats other classifications of light with disdain, repeatedly mocking them with a sarcastic tone: 'Pursuing truth all one's life is just to make oneself delicious and then be eaten whole.'

Only the purest light is truly real; any strange light is merely bait to lure in a mysterious entity!

Upon seeing this sentence, Yaro silently gave it a thumbs up in his heart.

Although that statement isn't entirely accurate, the author of this book is indeed a genius!

Arro, coming from another world, naturally knew that light wouldn't have those strange effects, but the author of this book was different.

He lived in this world, and the world he saw contained those strange effects of light.

Just like an apple falling to the ground, how many people would question why the apple fell to the ground?
Yaro continued flipping through the book, when suddenly a page caught his attention, and he quickly turned to the next few pages.

Light-based level 1 spell: Refraction.

Used to: refract light away from oneself, thereby achieving the purpose of invisibility.

"This trick... it actually revealed the entire structure?!"

Get a free magic trick?
No, this book was originally recommended to Bosco by his mentor, so it's impossible that he didn't know it was about this.

It's even possible... that he wrote this book! Yaro studied the magic trick carefully.

This is a pure light magic trick, meaning that the trick itself does not involve any strange light-based energy and is a spell that can be used at will.

Just as the Light spell summons scattered fire elements to illuminate the surroundings, the Fireball spell condenses fire elements to produce combustion.

Why can a light-based spell twist the light and create an invisibility effect?
As can be seen from the title of the book given by Bosco, he would not have seen that Yaro simply memorized the structure of a magic trick.

Learn knowledge, unleash magic, apply knowledge, and unlock the material world.

What Yaro wanted to do was to study the principles of this spell and learn the knowledge within it.

A moment later, Yarrow was impressed by the creator of the spell; he had already understood the principle behind the trick.

First, let's talk about a principle. Just as fire magic can guide the direction of flames and water magic can create towering waves, light magic can also guide beams of light.

Therefore, the light magic is used to cover a single direction in a semi-circular shape using a special net-like structure.

Then, the light rays coming from that direction will be deflected, thus creating an invisibility effect.

But there are still many problems.

What is the degree of deflection of light by light-based magic?

How large a coverage area is needed to completely block the reflected light?

Just like in Yaro's previous life, many invisibility cloaks have been made. Those were simply made using material structures, but countless of them could only appear in the laboratory and were difficult to actually be made into the world.

Similarly, refraction has a similar drawback: it is easily exposed in strong light unless the caster's calculation ability far surpasses that of ordinary people.

Yaro copied down the trick, intending to study it more carefully later. Although he couldn't use this light-based trick now, referring to it could bring him a lot of inspiration and direction.

Continuing to flip through this book, "Analysis of Basic Light-Based Magic," I found myself unknowingly turning to the last page, where the author left two questions.

1. Why is it difficult for spiritual energy to attach to light?

Using his memories from his previous life, Yaro had some guesses about this issue.

It's possible that the photons are too weak, and the matter volume is too small, making it impossible for spiritual energy to attach.

It may also be related to the wave-particle duality of light.

However, this had little to do with Yaro, and he skipped over the question after a brief moment of thought.

Question 2... Just how fast is the speed of light?
When Yaro saw this, his heart skipped a beat.

Could this be... an opportunity?

Is it possible that no one in this world has designed a solution for testing the speed of light?

No, that's not right. That's too arrogant.

Perhaps someone designed it, but the result didn't spread!
The world already has many limitations on the dissemination of knowledge. In addition, the power of a pure beam of light is limited, and few people study the speed of a pure beam of light, which may lead to this result.

Of course, Yaro didn't want to make a fool of himself, so he planned to go to the library again to look up information on this topic.

If it is confirmed that there is no relevant information in the library, then a crucial breakthrough will be achieved.
