Not many books are designated as forbidden. Therefore, this room is not so large accordingly.

That being said, the books are packed in a bookcase arranged on the wall in a section inside the large library.

Because it is underground, there are no windows, and the only light source is a tool that illuminates the light by passing magic power.

There was a table in the center of the room for reading, but now it is used instead of a simple bed to lay unconscious Cordelia.

"Ugh...... Guu......"

"Mom... it's okay, it's okay..."

Ethel gently calls out to her painful mother and puts her hand on the scar on Cordelia's back, lying face down on her face.

The particles of light pouring into the wound from the palm of my hand are basic healing skills called "Divine Magic: Regeneration".

I also gave you some potions, so I thought I'd be able to do something about it... but it doesn't work.

"(Speaking of which, as I got older, the potency of the potion decreased......)"

In the game era, there is no meaningful undercover setting, but it seems that as it becomes a reality, the setting has a definite impact on the people who live.

However, the setting behind it seemed to affect not only the potion but also the recovery by magic, and even the cheap potion was enough for first aid. Compared to me, the appearance was in my 30s, but the wound of Cordelia, who was over 70 years old, had only stopped bleeding.

In the wound carved by the flesh attached by the chain, something like a spine is seen as thin.

Even if I am an amateur in medical care, I somehow know what kind of consequences can cause damage to the spine.

I don't know if I can move it if I want to escape. All this will have to do is bet on Ethel and Cordelia's hard work.

For the time being, I let Cordelia-san hold the [Knight's Sword of Steel] in her hand.

This weapon has a trait called "Fine Regeneration" that restores 1% of max HP at the start of each turn.

In theory, it is 10 seconds per turn, so it should take about 15 minutes to fully heal, but this is also a healing effect, so the healing amount is likely to decrease significantly as well as magic.

To be clear, I don't know if I'm going to take it easy, but I guess Rika is better than nothing.

"Thank you, Thor."

"Hmm. Then let me know when Mr. Cordelia is able to talk because I'm researching something." Iris, I need two of you. "

Yes, I understand.

I asked Iris to assist Ethel and left the scene.

Not to mention Cordelia, Ethel's complexion is pale in the face of the fact that her mother was attacked and wounded.

What I wanted from Iris was not Cordelia, but her role as Ethel's Stopper, who continued to use her healing skills.

Even if her magic power is gone, she is anxious not to activate it and is in danger of falling into a spiritual vicious circle.

If Iris were next to you at such a time, you could convince her to rest gently.

It's a role I can't afford to give up or trim my consciousness for the time being if I find myself in the same situation.

"Ah, yes! [Aiko's Crystal Ball]!" Use this to call for help! "

Well, it's useless, isn't it?

"Why!?"

When I tried to extract the book from the bookcase I saw, I heard Ethel's voice.

She remembers the presence of the crystal ball in her pocket, and it seems that she found hope there, but I don't hesitate to deny it.

"It's very likely that they will be on the ground when we launch the raid, and they will be one of them." And... come on. "

When I take out the crystal ball I was receiving, I smash it to the ground.

Then Ethel noticed something, and she put her trembling hand in her pocket, and took out what was there.

"... shit!"

Is that so?

That's how it is.

What Ethel threw on the floor with anger was shattered [the crystal ball of Aiko], its remnants. Seeing that, Iris spoke up convincingly.

Judging from the timing of the shattering of the crystal ball that Ethel had, the [Crystal Ball of Aiko] that she had was linked to what was given to me.

I'm sure that what Iris had was linked to Cordelia's crystal ball.

In other words, the means of informing the ground of the anomaly itself has been sealed in advance. Now I can't even call for help.

"Then what should I do... what are they...!"

"Ethel, just think about healing your mother now." You're the only one who can cure that wound because the potion you hid is gone. "

"... I know, I know!"

What should we do now, and who are the assailants?

Ethel shakes her head wide to forget her anxiety and continues to turn on her mother and activate her magic.

I removed my gaze from Ethel's figure and reached for the book that would fit on the bookshelf next time.

As for the assailant, I don't know what he's up to, but I can give both of them a mixed guess.

But my goal in the first place is to find information in the books in this forbidden compartment that will help us solve the dungeon blockade.

"(It's too troublesome to give me an answer by guessing. I'm sorry for Ethel, but I'll prioritize my purpose.)"

Besides, even if you escape, in the end, you have to wait for Cordelia-san to recover, so don't complain if you use the time effectively.

So I decided to lay aside for a moment about the raid and focus on gathering information.

Fortunately, if we are protected from the outside world by the barrier, we will have plenty of time to examine the contained books.

So I tried a puzzle that switched the order of the books in order to reveal the hidden doors that existed in this forbidden section.
