Laboratory under the mountains [Edited]

As I started waking up, I felt a little pain in my body. I realize I was laying on the ground inside a cave. Or a laboratory I should say. According to my Skill Knowledge of the World, I am inside a secret laboratory hidden under the black mountain.

I began moving my body, trying to stand up. I looked around and saw multiple kinds of stuff, tools, machines, books, scrolls and paper. The place is in a mess.

That's because an accident happened here 6 years ago.

I looked behind me and saw a large tank made of glass, or in another word a Capsule. It was damaged and the glasses was shattered. The liquids that was contained inside it has dried out. This capsule was the container of the Homunculus's body that I am using now.

The story about this laboratory is that a scientist mage or a professor mage made this place so that he can do some experiments and research in secret. His name was Professor Mart Sellius, one of the great professors and mages in this world. He was also known as "genius and crazy" because he always comes up with crazy ideas in creating new type of spells and magic tools. Like, creating a magic tool that can turn any foods into water, which made many people think he was crazy. But he wasn't. He did succeed in finding the method but he didn't continue the research because of what happened to his family.

I turn my head around to look behind. On the ground about a couple of steps away from the capsule laying a body of a skeleton. A dead skeleton wearing a white coat.

That was the body of the Professor Sellius who died 6 years ago.

To explain what happened here I will start from the very beginning. Thanks to "Knowledge of the World" I know the full story.

____

19 years ago Mart Sellius's son William Sellius died in a war against the demons. And in that same year his wife Flora Sellius was pregnant with a boy. After the boy was born his mother became sick when he was 3 years old. She died from the illness when he was 4 years old, and his grandfather Professor Sellius took him in and raised him in the capital.

But unfortunately the boy had the same illness as his mother. The illness called "mana poisoning" which kills the body due to unstable in mana. In his 5th birthday the disease started to appear in his body. And one year after that, the boy died.

His grandfather has failed to find the cure because it has never been found yet. He tried researching, searching, looking for the answer but in the end he was too late. The cure of the mana poisoning was never been discovered and all kinds and types of healing magic had no effect to it, neither was it able to slow down the disease.

The boy's name was Lesten Sellius, and he was 6 years old when he died. He never saw his father and his mother died when he was 4. He lived with his grandfather in the capital but in his 5th year he got the mana poisoning. He saw his grandfather struggling, working hard to find a cure, but it was too late.

That was the first story, about the Professor's grandson.

The death of his son and the mother was so cruel to him and his grandson. But the death of his last family member, his grandson was too hard for him.

Five month after Lesten's death, the Professor left the capital and disappeared to the black mountain.

He wanted to research there alone and in secret, to find a way to bring his grandson back to life. If the people found out about this, they will think he got more crazy and many professors, mages, and high ranks will try to stop him. Because what he was doing something more madness and a taboo.

Bring someone back to life means using many types of dark and forbidden magic that can bring disaster to the world. There were people in the past who tried to use some types of Resurrection magic to bring back the dead, which end up in creating undead creatures and zombies.

And if the professor use those methods, he may end up creating something worse than that.

Fortunately, the Professor wasn't going to use that method. He might be crazy but he wasn't stupid.

He tried finding another way to bring his grandson using pure methods. 4 years in the laboratory that he made in the mountains he kept researching for a way until he found one.

He found out that when a person dies the soul leaves the body immediately leaving the world too. Mart thought that in order to resurrect someone he needs to find that soul first and bring it back to a new body, since the formal body can't be used anymore when the soul leaves it.

So he used Time and Space magic to locate Lesten's soul, and he succeeded, but the hard part was to install it in a new Humanoid body.

In order to "rewind back" the soul after it left the world he need more mana. So he gathered alot of magic stones. And he needed full control in manipulate the flow of mana. For being one of the great and talented mage in this world he was very close in succeeding his goal.

But in the end he failed.

For not being able to fully control the flow of mana 100% since he was using a very high level magic spells, it end up destroying his mana pole, ending the old man's life.

That was the full story.

____

I walk toward the Professor's dead skeleton, kneeling down and start praying while closing my eyes.

...

Although the method he used wasn't wrong, unfortunately it wasn't the method that he was really looking for, even if he succeeded.

You see, when a person dies, their soul leaves the world immediately without leaving any trace. The soul goes to the "reincarnation cycle" leaving all the fragments it had about it's old world.

What the professor found when he tried to locate Lesten's soul was just the fragments of the soul that was deleted.

When a soul leaves to the reincarnation cycle they Lose all their Memories about their old world "their past". And those memories are what made those souls who they were before they die.

If the professor did succeed in resurrecting his grandson, then the boy will be just a Copy of the real one.

Just like Kirito's Copy.

And what the Professor really wanted was the real Lesten to come back, not a copy.

After finishing praying, I stood up again and took another look at the skeleton.

I feel really sorry for him and his family, especially the boy. Losing both his parents and ending up dying from an illness in a very young age.

I also have some respect for the Professor.

Working very hard to find a cure. And even finding a way to bring back his dead grandson without using a Bad or an Evil methods.

He was a genius and a very crazy old man. But he was also Pure in his craziness.

[I hope you don't mind me using this body since, you don't need it anymore.]

I spoke to his body.

Although I already Know he wouldn't mind, I feel like I should ask first.

I look around to find something that might help me see my reflection. I walk toward a metallic machine which was the energy reactor for the capsule and looked at my face reflection.

I looked young, and my appearance was the same when I was 14 in my previous life, but a little different. The hair is silver white, and the eyes are deep green.

I look like those people who cosplaying one of the anime characters.

But this face, it's look more real than the fake one.

[Ok then, first thing first is to check this new skill.]

M said that the skill automatically responses to my Will, so if I have any questions or information that I need to know it will answer it.

Let me see, first I need all the information about this skill.

<Information about the skill "Knowledge of the world" installing...>

[Hm!]

<Information Complete.>

...

...

That was so fast! Right in an instint,I already know what I need to Know about the skill.

It's seems that "knowledge of the world" can only provide me with the information that I really want to know. Although I already know all it's function and how to use it, there still more information it has stored.

[let's check the Library first.]

<Would you like to use Knowledge of the world's Library?>

Yes!

<Entering the Library: begin the process..>

...

...

My vision started to change and I was teleported to somewhere else.

...

The First thing I saw was the notification screen in front of my view.

<Welcome to Knowledge of the world's Library.>

I am now in a Library. A very large, big, gigantic Library!

[This place is so freaking insane.]

I commented as I looked around me. Right now I am standing in the middle of the Library, with multiple books and book shelves around me. In front of me there is a desk and a chair. They both look very luxurious.

I went there and sat down on the chair, It felt so comfortable.

[Now, let's see what I can find.]

I raise both my hand in the air, ready to do something.

Oh right! I forgot to explain to you guys before that.

Since you don't Know, hehe'.

(A/N: he is using Vanti's "hehe")

Right now I am inside the skill, which is also can be said that I am inside my mind.

It's like Vivy's mind which looks like a classroom for music from the Anime "Vivy fluorite eye's song". And where she can gather information about songs, lyrics, music and create new songs.

While mine looks like a giant Library for information and knowledge, where I can search any kind of information about this world.

Because I am a Homunculus, my mind and brain are like an AI. I can think fast, memorizes more, and analyze better than any other races in this world.

If I had chosen Human or any other races I would end up getting a headache every time I install a new information.

Moving on, this library is where I can read the information I want to know through books.

For example.

<Searching about: This world magic.>

A projected screen appeared on the desk with those words written on it.

What I did was typing using the keyboard that was projected on the desk, although I could also just use my mind without the need of a keyboard.

I feel like Tony Start if I do that.

<Search complete.>

Suddenly, Multiple Books appeared on the desk, 5 of them. These books contains all the information about Magic in this world.

I took the one on the top and opened it.

The books may look like it has about 200 pages, but actually when you open and start reading, it will feel like it has over 2000 pages.

From the outside it looked like a little, but from the inside it a lot more than that.

I closed the book and put it back on the top.

In this Library I can use it as a place to read and search. The skill "Knowledge of the world" can provide me with the information in two ways.

Through installing, where I can know about new knowledge in less than a second. Or by reading the information as books in the library.

The difference between them is that the first method only installs the information that's more important about the things I want.

For example, If I want to know how many days, months, and seasons this world has it will answer in complete.

But if I want to know everything about this world's History, it will only give me 40% of the answer, without the details, only the important things.

Because my mind wouldn't stand all the Full information about it, from the first day of the history until the present day, in a full detail, a 100% full history record.

Installing an information this big may end up destroying my brain. No, it will definitely destroy my brain and end my second life, even if my brain was like a supercomputer.

Fortunately, "Knowledge of the world" knows how to short cut the information like those one.

And if I want to know the full History of this world with the details, I could read it in this Library, all of them.

By the way, the Books about this World History is 4728 volumes in this Library.

[What's more cool about this Library is not just I can read the information through books only, I can also watch the events and the history on the screen.]

I typed "The world geography" then the screen showed a Live video about this world.

I can see Lands, Mountain, Rivers, Ocean, Village and Cities.

I can use this place as an HQ for gathering information and Intel, with videos and sound, if I want to find my enemies and spy on them.

*Evil smile*

Well, I don't need to think about this kind of things now since I don't have any enemies.

Yet.

I think I will use this Library when I go to sleep. Because in this place, times accelerate 10 times in the real world.

Spending 10 hours in the Library is 1 hour in reality, since my mind is an AI.

Just like Vivy's

<Do you want to exit Knowledge of the world's Library?>

[Hmmm.]

The name of the skill is too long to hear. I think I should make it short.

<Do you want to change the Name of the Skill?>

[Yeah.]

< Change the Skill's Name:___ !>

Now let me see...a short name for my skill.

...

Knowledge? ...Too weird.

...

A great Sage, Lord of wisdom.

Nope, those names are weak. My skill is way more knowledgeable than Raphael.

...

...

How do you say "Knowledge of the world" in Japanese?

<Ding!>

<Sekai no chishiki>

[Oh, thank you sensei.]

So, Sekai No Chishiki huh.

Hmmmmm.

Got it!

<Change the Skill's name: Senoki.>

<The name of the skill " Knowledge of the world" has been changed to "Senoki">

Much better. Now, let's leave this place.

<Do you want to exit Senoki's Library?>

Yes please!

<Exiting the Library...>

My vision changed again, I am now back in the Laboratory.

I guess I will try looking for more books in the Laboratory next time, and maybe try reading about some magic.

Grrrrrowll!

[.....]

Looks like I'm hungry?

Well of course I will feel hungry even if I am a Homunculus. I am a man made human. Correction, my New Body is a man made human.

I look down at my stomach while rubbing it.

Hm?

I just realized something.

I am naked.

[....]

[I thing I really have some problems in realizing my own surrounding.]

Especially my own body. I recall what happened a few hours ago when I was talking to M.

The scene where I had no body or brain, and all my thoughts can be heard by everyone.

I shook my head trying to forget about it. This was the second time something like this happen after I died.

[let's hope there won't be a third time.] I murmured.

*****

After exiting that room were the capsule was, I went to the Professor's bedroom to get some clothes. They were all bigger size for a boy who is 14. Well, can't be helped. The Laboratory in the mountain is very large with multiple rooms, an research room, a bedroom, a bathroom, a lab for magic potions and inventions, a storage for items and tools, a kitchen, and a large pool for fishing?

Not really, the pool was used for magic fishes and sea beast, although there is none anymore now.

Right now I am in the kitchen eating some foods that was left in the kitchen storage.

What am I eating you ask?

Sandwich.

With boar meat, tomatoes, bread and cheese.

Where did I got those? The kitchen's storage obviously.

The storage has some magic ruins written on the walls that stops the food from rotting. There are many foods in there that can last for 10 years.

Now it can only last for 3 years because 7 years had already past since the Professor made those ruins.

As for the kitchen's tools, they are all still can be used.

While eating, I was looking at the small screen in front of me which contain multiple information.

Same as using the screening when I was in the Senoki's Library I can also use it out here.

Like Satou.

It's feels like when I am using my smartphone with one hand and eating chips with the other hand, except this time I am using both hands.

What I am checking are some informations about this world's magic.

It's seems that there are two kinds of magic. The Elemental magic and Non Elemental magic.

Elemental magic are magic which use the shapes of elements like, fire, water, poison, plant, sound, light, dark, time, space, etc.

And the non elemental magic...well, like the name says, it magic that are not using shapes of elements like curse magic, sealing, telepathic, boost, flying, mind, acceleration, senses, etc.

Although it's only two kinds but every type of magic has multiple sub types, for example the fire magic, from the fire magic you can use flame magic which is more stronger than fire magic, fire manipulation magic to manipulate fire, cold flame to create a fire that is cold and freezes the enemy, dark flame which is a fire that are black color and more stronger, and many other things.

Same goes for the non elemental too. An example for it is the Mind magic, from it I can use mind connection to use telepathic, mind acceleration to think fast, mind manipulation or mind control magic to control, confuse, or make illusions to the enemy like Gen-jutsu.

Everyone in this world can use magic as long they have MP. MP refers to "mana pool" not "magic power", don't mistake this world like in the video games.

[As for how to use the mana and cast a magic spell, that's easy.]

Swallowing the last bite of sandwich that I already finished, I open my right hand and closed my eyes. Then I start concentrating, with the help of Senoki sensei, I already know how and what it's feels like to use magic. Inside my body there is mana pole, let's imagine its shape as a box or something that is filled with liquid of mana, then open a door hole on the box to pore out some mana, and connect it to my right hand so that the mana can be transfer there and gathering it. Now I need to change the mana in my hand to create a magic spell. The spell that I want to cast is Wind magic.

Yes wind. Not fire ball or water ball, but wind ball. I wouldn't imitate those isekai characters who uses strong spell in there first try.

The reason I choose to use wind first is because it's the most easiest and fastest magic to cast. I can use fire or water but it's takes more time and mana. If I want to cast fire magic then I will need to change the mana into fire attribute. But for wind magic, I only need to manipulate the air around me. A person can cast any elemental magic by changing the characteristics of the mana into the element that he want. But using the mana in manipulating the environment around him to change it's characteristic into elemental magic will cost less mana to consume.

I opened my eyes to see if the spell worked. The air around my hand started to change forming multiple winds that rotating around creating sphere ball of wind on top of my hand.

[It's feels like Rasengun.] I scoffed with a smile.

It's dosen't looks the same actually. The color is not blue but white, and the wind rotation is one way.

I looked to a clear wall and aimed my right hand at it.

[Wind Bullet.] I pronounced the name of the spell in a low voice.

*Blast!*

*Boom!*

After releasing the spell from my hand it dashed towards the wall that I was aiming. It hit the wall creating some small dust around it.

[It's a good thing I used a little.]

I looked at the wall that has a small mark of sphere on it now. Just to let you know, I used a very little but enough mana in my spell. Why? Because I don't want to end up creating a First Mark of Destruction on my first spell.

Like I said before, I won't imitate those main characters who "Accidentally" fires a large spell that leaves a Large Mark in their first try.

Well, most of the main characters are actually Newbies, so of course they will Accidentally destroy something because they don't know. As for me? yes I am a Newbie too, but I am different. Because I Do something after I Know how to do it correctly.

Next I tried using the other elements attribute. Water start forming on my hand creating a water ball, success. Then I raise my left hand to create another spell. A small flame suddenly appeared on my left hand, like as if my hand was a Lighter. It grew a little more until it was in the same size as the water ball. Both were in a size of a pingpong ball.

Then I move them close, making the two spells touch each other.

*Pofffffff*

The water ball got evaporated by the fire ball creating a small smoke. Some of them entered my nose.

[Cough-Cough.]

Looks like the winner is the fire element, I thought both spells would disappear in creating a smoke reaction like in the game. Why wasn't the water able to put out the fire with it?

<Ding!>

Hm? Oh so that's why~. Because of the differences in mana. I put more mana in the fire ball to make it reach the same size as the water ball, which made the fire more stronger. It's not the size or the weight, but the amount of mana.

*Huff*

I blew away the fire ball that was on my hand, then I  used both hands to create earth magic. Unlike wind, water, and fire, earth magic is harder than them when creating it. Ofcourse I can use the ground to make it more easier, but I want to test how to change the characteristic of the mana into an element attribute. The process took 12 seconds for me to create a small rock, the size of an index finger. The wind, fire and water that I cast took less than 5 seconds to appear, as for the earth, it tooks 9 seconds.

[If I use the ground to create the same spell, then it will take less than that.] I murmured.

I start casting more other spells after that. Lightning magic, ice magic. poison magic, which I only use a poison that's harmless to me. Plant magic which need the support of the ground, because you can't create a plant from a thin air, you need an Earth ground or a soil to do that. And shadow magic to move my shadow.

Well, I think that's enough for today's test. I used alot of mana. I need to recharge, which means I need to sleep.

*Yaaaaaaaawn*

[It's time to go to sleep.]

And also visiting the library.
