“It’s normal if you use it in the village, huh.”

“Yes. No problems, until today.”

After defeating two greywolves in the Demon Forest, we came straight back to the village.

When we returned I told Sui to test her magic out, but her [Water Sphere] kept coming out normal-sized.

“Lain, is Sui going to be okay?”

“Hmm. She should be…”

The size of a [Water Sphere] was proportional to the magic incorporated in it.

The size that Sui produced in the forest should not have been possible even if her current self used all her magical power.

That it happened regardless, means she dragged in magical power from elsewhere.

(The problem is from where.)

The most suspicious would be that spell book.

But even though she was holding on to it right now, it wasn’t affecting her magic whatsoever.

I then suspected she was using her life-force.

However, even when using magic for sensing vitality, I couldn’t detect any changes in her life-force.

“Hmm, I wonder why.”

“Lain.”

“?Yeah Sui?”

As I tilted my head in confusion, Sui pulled on my clothes.

“”Probably, my magic is getting stronger, by sucking magical power, around me.”

“?What do you mean?”

“Whenever I, use magic, it swirls, and gathers around me.”

“…That can’t be.”

There were plenty of reasons why sorcery was considered stronger than magic.

One of those being that it incorporates magical power found in nature into your own mana pool, and allowed you to use that.

Apparently those characteristics were lost during the development of modern magic.

As an example, magical tools such as the alchemy pot that have existed since the magical era absorb the magical power of the surroundings and produce greater results than the power provided by the smelter.

Sui might have been influenced by the spell book to utilize sorcery’s special ability, and use it with magic.

“In any case, this is very dangerous.”

Aria asked worriedly.

“We seal it. Or rather, we store it inside the space of my storage magic. That should be our safest option.”

There was no doubt that the book was influencing Sui.

Till now we had only seen positives, but there was no telling what might happen with time.

It’s better if we took it off her hands.

“What will, you do? You can’t, touch it.”

“No need to worry, I have my own magic tool for that.”

I took out a bandage-type tool out of my [Storage].

This is the magic tool used to seal spell books. If we wrapped this around it, we’d be able to suppress its power.

“Why do you have something like that?”

“It was used to seal my own spell book.”

“Eeh!? Is your spell book okay?”

“Its power has long surpassed that of this magic tool, so it won’t have an effect in any case. I’ll have to soon find a replacement for that as well.”

“Soon, you say…”

I quickly wrapped up the spell book, while Aria gave me a stunned look.

Once wrapped, the book could be touched by anyone, including me.

I quickly stored the book inside my [Storage].

“Phew, that went well.”

“There’s no problem now right?”

“More or less for the time being. If the spell book broke itself out of the sealed magic tool, it would undoubtedly return to Sui.”

“Eh? Really!?”

“Though I can say that won’t be until a few years later at least. We’ll have to find a stronger seal by that time.”

“That’s like a game of cat & mouse. Isn’t there a better way?”

It’s certainly not a solution by any means.

If we waited for book to break through its seal, only to bind it with a stronger seal and continued this process forever, we’d ultimately run out of strong enough magic tools.

“What’s left is to find out who that spell book belonged to.”

“Find out, who’s book, it is?”

“That’s right. A spell book means its contents are related to sorcery, so that means there had to be a witch or a wizard who put those contents to use. Supposedly, if you formally sign a contract with the spellbook in the name of that person, you will be able to manipulate the spell book at will.”

A spell book was classified under sorcery.

Although Sui was chosen as the owner of the spell book, she was in a state of provisional contract, with no proper contract or ritual.

Therefore, the power of the spellbook could not be turned on or off, and we didn’t get to know what kind of power the spell book had in the first place.

If we took it to where the former contractor was, Sui would be able to manipulate it at her will and the risk related to the spell book becomes virtually zero.

“I don’t think there was anything in those ruins regarding that. The books didn’t have anything related to sorcery either.”

“Um, Lain nii-chan?”

While we were talking about the spell book, Reno spoke up hesitatingly.

“Mm? Reno, did something happen?”

“…..”

I asked her as gently as possible, but she only opened her mouth slightly before clamping down again.

Regardless, I waited for her.

Aria and the rest also waited for Reno’s words, and the silence continued for a while.

“…Everyone was in panic at the time so I didn’t say anything, but we still haven’t fully explored that room in the ruins.”

Reno dropped a bombshell on all of us.
