Instead of the marble-like stone that Dia had exploded, he took out a new stone.
　Magic is more dangerous than one might think, that just measuring magic power can cause a huge explosion.
　Hence, it can also be a powerful weapon.

However, when you think about it calmly, it's no wonder that such a phenomenon happens.
　The magic power in that stone is a third of my magic power, which is equivalent to a thousand people.
　In other words, the magic power of three hundred ordinary wizards has gone out of control.
　Just by putting magic power in it, it became like that.
　If I devised it with exploding in mind, I could raise its power even more.......great.
　After all, I want that ball.

You're looking at it like it's something you want. You can't have it.

It seems that he has read his greed, and Dea, the Master, holds the marble with great care.

'After all this time, what's the name of that ball?'
"Foul stones.

Let's remember.
　He says you can get it in Deer's territory, but it won't be the only place you can mine it.

I'll give you the foul stone again, Lug, but you can't take it. This time, give it back to me with all your magic for 10 seconds. If it were true, I'd have you put all your energy into it and measure the amount of magic you have, and then look at the stone to see what attributes it has, but because of the explosion, it's twice as hard.
I'm sorry.
'Nope, no need to apologize. It's the first time I've ever learned that if you go over the limit, you'll explode. Now, hurry up and put some magic into it.

I return the foul stone after I put my magic power in as I was told.
　Dia grips it.

''Well, let's try it with fire first.

When she reminded him of something, the transparent stone glowed red.

''Let's see, the rogue's aptitude attribute is fire. Just in case it could be a dual attribute we need to look at the other attributes as well.

As he said this, the color of the crystal returned to clear again, and then changed to light blue.

'Oh, great. There's an aptitude for water, too. This is the first time I've seen a child with dual attributes, except for me. It's super rare. I might as well brag about it.
What was that?
'Try to stimulate the magic contained in the foul stone with each attribute to see if it changes. Aptitude would be each attribute.
Okay, then can you try the other two attributes?
'Okay but I've never heard of more than a triple attribute. ''Hare?　Why, and the suitability of the soil!　No?　All magic users, even the wind, are mages with all four attributes?　This stuff is real.

I was allowed to choose the goddess.
　I finally have proof that I can use the four attributes.
　However, instead of being able to use the four attributes, there's a disadvantage that the speed of improvement of each attribute is less than half. ........Well, that's also a disadvantage that can easily be compensated for by leaving it to the power of [Super Recovery].

''Looks like it. We now know the amount of magic power and attributes. Well then, what do we do next?
'I can't believe it. Huh, but I think I'm getting used to it. I'm not surprised by anything Lug does. I'll make sure you're well versed in it. I'll show you the magic.

Then she stands behind me and puts her slender hands on my neck. It's cooler than my body temperature.

"Ready?　You seem to use magic power on a regular basis, but magic is something else. In order to perform this magic, you need to convert the magical power into an attribute. I can help you with that. The first time you transform an attribute is an intense experience and will be remembered. So if a bad master guides you, you'll develop a strange habit.
'Dia isn't a bad teacher, is she?
'I promise you that you will have the nicest first experience of anyone. .........Oh, I don't mean that in a weird way!

I didn't mean it that way.
　He's a bit of a strange child.
　Mysterious power is flowing in from the neck.
　Just as the magic power in the foul stone was transformed, the magic power in my body is being directly transformed?

''Concentrate, rogue, the first one is earth. That's my strongest attribute. Feel the change in magic power on your skin and take it to heart.

As you were told, close your eyes and feel the changes in the magic power inside your body.
　I learn the sensation of magic power being transformed and changing its shape.
　It's comforting.
　I've never been done by anyone other than Dia, so I can't compare, but there seems to be no doubt that Dia is good at it.
　However, those pleasant times are coming to an end.
　Dia lets go of my hand.

'You've learned it already, haven't you? Try it.'
Thank you for a wonderful first time. ... you've given me a pretty good idea. Like that?

My body learned. So I can do it.
　As Dia guided me, I'll turn my colorless magic into an earthy attribute.

''It's still rough. No matter how big your magic power is, if you can't convert it well, it's useless. Ordinary mages are at most sixty percent of the time. But I'm the one teaching them. You have to achieve at least 80% conversion efficiency.

Only attribute converted magic power can be used for magic.
　In other words, any magic power that couldn't be converted would be lost.

I see, so my father carefully selected his masters.
　If a bad master could develop a strange habit, the mage would suffer the loss of magic conversions for the rest of his life.
　He set a really good example.
　I can see it when I try it myself.
　How great the magic transformation that Dia casually did was.
　Remember, that technique.

'Well, it's not so easy to do. Years of training, wow, you've already improved so much!
'Because of the good example. Still, you're not far behind Deere.
"My pride will be blown out of my mind if they catch up with me on day one!　Even though this is still called genius....The attribute conversion of magic power is basic and profound. You have to train it every day. Hmmm, there is no end to it. And since rogues have four attributes, it's four times harder.

Strangely enough, now that I can convert earth, the remaining three attributes, I somehow know how to do it too.
　Let's practice a little bit every day.
　As I was improving the magic power of the earth attribute in this way, something like a character I had never seen before, like a diagram, appeared in my mind.

'Ah, that face, you've learned magic.
This is witchcraft.
Yeah, when you wear a certain amount of attribute magic, you get a revelation from the gods and learn magic.
Well I'm sure it's all in my head, but how does it work?

I can't even read it, just a bunch of letters that I don't understand.

'Chanting while increasing my attribute transformed magic power I can just read out the letters that pop into my brain. Watch.

Deere spins poetry in an unfamiliar language with a beautiful voice sound.
　The pronunciation, the accent, it's completely different and alien to the language of this country. When the chanting ends, a lump of lead is born from her hand.

'This is the first magic that comes to mind with the earth attribute. The first magic that comes to mind is this, the magic that creates lead. The more you use magic, the more new magic comes into your mind. God will give you new magic. I've created soft lead now, but if I forge it, I can create harder iron!

It's true that iron is harder, but that's not to say that lead is backwards compatible with iron.
　And I finally understood. Does this mean that I can usually only use the magic formulas given to me by God?
　It's interesting how the number of magic techniques that can be used increases in my brain with each repetition of the attribute magic.

'I'd like to try it too, but I can't read these strange letters, or rather, diagrams. Can you tell me how to read these letters floating around in my head?
'Yeah, that's the basics. Magical letters are all about correct pronunciation!　Because the correctness of your pronunciation affects your accuracy and power.
It's not easy to be both a magician and a good chanter.
It's a pain in the ass, and there are many people who don't use magic at all from the beginning because of its weaknesses.
Is that true?　The lead-generating magic you just showed me alone seems useful.

At any rate, just throwing a lump of lead is enough of a weapon.
　It is a great advantage to be able to take out a weapon at any time. Especially in assassinations, you don't have to carry a concealed weapon.

'I told you. It's not just a hassle, it's a weakness. It is said that magicians have the power of a hundred ordinary people on the battlefield. That's because when you're clothed in magic power, your physical abilities and defense are improved. However, while chanting, they pour their magical power into their magic, so their physical abilities and defenses are no different from those of a normal person. It's quite dangerous. So, I can understand why you wouldn't use it at the beginning.

Indeed.
　Especially being defenseless at a distance where the blade can reach you is fatal.
　Even so, there is potential in magic.

........Besides, I've gone to the trouble of obtaining the power to create magic called 【Formula Weaving Things】. It would be a waste not to use it.
　There is a magic that produces lead, and at a higher level, a magic that produces iron.
　If that's the case, isn't it possible to create magic that can produce metal more suitable for battle by modifying the magic formula with 【Formula Weaver】?

For example, titanium, which has about the same hardness as iron but weighs about 60% less and is suitable for weapons.
　Tungsten, which is super heavy and super hard.
　If we can make a light and strong slashing weapon with titanium and a spear or bullet with super-hardness and penetrating power with tungsten, it would be a big increase in war potential.
　With the technology of this era, at best, poor quality iron mixed with a lot of impurities is used for weapons.
　Being able to use weapons made of stronger metal would be a great advantage in itself.
　The fact that it is possible to create metal from nothing in the first place is amazing. For example, if you jump high and then create a super-heavy metal, you can generate tremendous kinetic energy just by hitting it.
　........In addition, wouldn't it be a pseudo-firearm if the bullets created by earth magic were spun by the explosion of fire magic?

If they could create a foul stone with magic, they could always make a bomb with great firepower.
　All at once, a myriad of possibilities could be seen. It was just one magic technique. If you know other magic techniques, you'll get more ideas.
　First of all, I don't mind that I can't use my magic power to protect my body while chanting. I'm not a warrior, I'm an assassin.
　I've already failed when I'm falling into combat. I usually kill them unilaterally from a safe zone, and I don't care about the disadvantage of losing my defense when chanting.

''Um, you've been smirking all the time since just now, what's going on?''
Yeah, I'm sorry. I'm sorry.

I'm getting excited just thinking about it.
　However, this kind of validation is still good for the future.
　First, I have to learn the magic letters, be able to pronounce them and perfect my chanting.
　Only when I can chant ordinary magic fully can I apply it.
　Dia would be able to teach me how to pronounce it perfectly.
