Life Hunter

After a minute of thought Arima pointed at the light he had created earlier "You see this light, right? It is actually produced by something we call electromagnetic waves. Those electromagnetic waves can actually do a lot of things, and the visible light is only a small part of it. These waves are determined by what we call their frequency or their wave lengths" He explained

At this point, the smarter students could more or less follow but even the ones who didn"t understand were writing on their notebooks.

"So, I won"t go too much deeper on that. But remember one thing, the light you usually see is produced by electromagnetic waves, and once its frequency goes over or below a certain limit, it isn"t visible with the naked eye anymore. And it also starts to gain different particularities" Arima resumed.

"Now look at this" Arima waved his hand and something like a timeline was projected in the air. If someone from the modern world was here, they would recognize this. It was the frequency scale of electromagnetic waves.

"A small part of this line is visible light" Arima said and two points on the line shined "These two points represent a certain frequency, and between those too, there it the visible light" He explained then looked at his students "Do you follow so far?" He asked and everyone nodded, kinda.

"Well, just note it, you"ll ask me what you don"t understand after" He wryly said and continued "Below visible light, well, when the frequency increases, there"s UV"s" He said and another part of the line was defined by two points "But we won"t talk much about it, and go even below. At that point, there is X rays" Arima said

"X rays are ionizing, meaning that they are very harmful to the human body, they can create serious illness and health problems. But you can easily protect yourself from it with magic. Now, the most useful way of using those is like this" Arima said and waved his hand in front of Night. A sort of gray screen formed and prevented the students to see Night"s figure. Arima pointed at the light in the air and brought it behind Night.

Arima"s sigil glowed and the light disappeared, at least, with the naked eye. Instead, a skeletal representation of a small wolf cub appeared on the gray screen.

The students exclaimed at such a strange phenomenon "What I did here was using the X rays to see Night"s bones" Arima said and made disappear the screen while making come back the light from before.

"The X rays pa.s.s through the flesh easily and will make a black mark on the screen, while when the rays pa.s.s though bones, which are more dense, they will create a white mark, outlining the bones. The screen is usually made in metal, I just reproduced a similar effect" He explained.

"In my homeland, this technique was used in medicine" Arima declared "But I want you to remember that it"s really dangerous if you are constantly being in contact with it" He warned and everyone nodded.

"Next, there is the gamma rays, with a higher frequency, even more dangerous than X rays. They"re highly penetrating and can, not only weaken your body and provoke illness and mutations, they also can damage internal organs and the bone marrow" Arima explained "So, basically, highly dangerous" He said to conclude.

"Now let"s go back to the visible light, with a smaller frequency, you stumble upon infrareds" One part of the line was one more time defined "Those are not really dangerous, they can be, but not as much as X or gamma rays" Arima said "But, infrared radiation is useful for one thing"

"To show you" Arima plunged the room into darkness "All of you, close your eyes" He smiled and instructed. Everyone did as he said. Arima"s sigil and eyes, glowed in a red light and all of his students felt a warm feeling in their eyes "Open them now"

When Arima said so, they opened their eyes, and everyone exclaimed. Red. They could see Arima and their cla.s.smates, but it only was their silhouette.

"Okay" Arima said and light returned "What you just experienced was thermal vision. Each source of heat releases an infrared radiation, when you find a way to see those radiations, you can see everything releasing heat around you" Arima paused and smiled "Of course, humans as well"

Arima waved one more time his hand at the frequency scale "The last one, microwaves. I"ll be quick, these waves interact with matter and are usually used to heat things. But of if you overload the quant.i.ty, it could do scary things" Arima grinned "Like frying your brain, for example"

The students gulped and nodded strongly, to say they understood.

"Good" Arima clapped "The rest are radio waves and are not useful for you. The reason I explained you all of that, was because gamma rays, X rays, infrareds and micro waves can be extremely useful. And also, because magic is always stronger when you know the principle behind it" He smiled "Now, if your apt.i.tude with light magic doesn"t increase then something"s wrong" He said and looked at Ofia. The latter nodded with a serious expression.

"Well, that was the underlying process as to how light is produced" Arima said "Now let"s talk about was the visible light can be used for"

"The first use I can tell you about is projection. The projections I"m making to help you understand, like this line or the figure. Now, as to how it works, I won"t go in detail, but basically, colors are deeply related to light, so that why you can create projections" Arima explained.

"Second use, concentrated light, or laser, if you prefer" Arima took out a metal plate from his storage and placed it in the middle of the room "Simply said, you gather light and condense it into one point" He said and pointed his finger at the metal plate. A bright light gathered and shot out of Arima"s fingertip.

The laser instantly pierced through the metal and left a hole on it "Well, it"s not really new for you" Arima said and stored back the metal piece.

"Third use, light is of course made to illuminate and blind in a fight, it"s also a good crow control, as it can lead people on a battle field" Arima declared and shrugged "Now, that"s all you need to know about Light"s basic properties, let"s continue with magic theory"

"When you use Light magic, the first thing that comes to you is simply purification. For example, with a chant like, "[Shine upon darkness, and expel evil]". Of course, it"s only an example" He said

"Remember also that light works better on darkness, of course. So, to cleanse darkness, you usually use light, but it"s also very good against death magic. Although its counterpart, life magic, is better, light is a huge threat against undead" He explained

"Another example, "[Reveal the truth for my eyes to witness]". This kind of chant is basically used to destroy illusion, arrays, mind effects and many others" Each time Arima listed something, a projection depicting the idea formed in mid-air.

"Well, it"s pretty much what you need to know about light, so because we still have time, I"ll talk about darkness, which is most complicated among the eight elements, but although it"s said to be the most complicated, it"s also the simplest there is" Arima wryly said "Because there"s not much to say about it"

"I can"t explain you what darkness is, because I don"t even know if someone has already thought of darkness as anything else than a lack of light. The only thing you can do with the direct ability of darkness, is simply create shadows, hide in it and maybe fight with light directly. But in the end, darkness can"t really be used in a first-degree application" He explained "Most of its power can only be shown when you use magic theory"

"With second degree application, you can make of darkness your strongest weapon. It can become an endless pit, capable of absorbing everything. It can also attack people and rob them of everything" Arima smiled

"Darkness is often mistaken as evil, but magic is not evil, only the ones using it. The magic theory of darkness is basically everything that lurks in the shadows. And contrary to light, which can"t hide anything, darkness has a lot of things to hide" He grinned and conjured a ball of darkness in his hand.

"It can hide anything, because we can"t see through it. It could be nightmares, monsters, pain and grief, death and life" As Arima kept talking, shadows kept getting out of the dark ball and hover around in the cla.s.sroom "And the most terrifying monster hiding in darkness, is none other than fear itself"

Arima said and darkness one more time invaded the place. But this one was a lot different from before, it was cold and it made one shiver in fright.

"Darkness means a lot for humans, when you can"t see anything, you generate fear. Loneliness, no light, no path, no escape. It means fear, sadness, sometimes anger, other times it"s despair. But you also find death at the end of the path" Arima slowly spoke and the obscurity suddenly dispersed.

At that moment, Arima instantly observed every student, he was looking for people who didn"t fell for the intimidation. Arister and Ofia were a given, and along with the others he had chosen, Arima found two others who didn"t seemed scared at all.

"Let me tell you this to finish. There"s a lot of stories about people being evil and using darkness. But the real reason for that is because darkness is more suited for them" He said "Why do you think people turn to be evil? It"s not because they want it, they became evil for a reason. Everything has a reason, there"s no such thing as destiny. Rather, cause and destiny should be the same thing"

"If I needed to say why people are evil, I"d just say because there are too much people who can"t understand the difference between evil and good. That ignorant ma.s.s just keeps pushing people toward the path of good or evil without taking care about the opinion of the said person. They just need someone like that, they need evil people to fear and they need good people to rea.s.sure them. It"s pathetic" Arima said with an infuriated tone.

"To be honest, I think evil people, are the right ones while the good people are just some idiots. Now, as to why evil is connected to darkness, it"s because to use the latter perfectly, you need to understand this world, you need to feel the fear, the pain and the death lurking around you. People who can notice that, are the smartest ones, who always fail to find any reason to be a good person"

The whole cla.s.s fell silent. They didn"t expect their teacher to suddenly talk about things like that. Not only that, they felt the hidden meaning behind those words.

Was their teacher evil?

Arima sighed, he clapped and stood up "Fine, that"s it for this lesson. Next time I"ll talk about the six others elements, don"t worry they are simpler than these two" He said "You two, you can stay, the others, leave the place for the next cla.s.s" He declared and the students left the room in the next moment.
