Even if you succeed in jobless reincarnation and time magic, you must live life to the fullest.

Yes, there was indeed no follow-up.

because……

Laplace, the Dragon King, died in that war.

The one who was subsequently resurrected was a being called the demon god Laplace.

I can not be reconciled.

So he continued searching for other books by Laplace.

But no matter what, there was absolutely no information about that demonic secret technique.

"..."

I calmed down a bit.

Rostina...

If that modification had been successful, Rostina should have been alive in the modern era.

However, he lost his memory due to the modification.

tsk...

Wouldn't that leave no trace at all?

"what!"

When I was troubled.

Suddenly, Hilfi spoke from afar.

"What's wrong, Silphie!"

I immediately stood up to ask, while turning to look at the demon king.

The other party did not make any strange moves.

"Found it! We found the book!"

"That's what Hilfi shouted."

Upon hearing the sound, everyone immediately gathered around Hilfi with me.

Hilfi took a book off the bookshelf.

The cover has a red leather strap and a picture of fruit growing on a tree, and it is very thick.

no doubt.

This is that person...

Diary of Dirich Barrebart.

244. Return

Ariel and the others gathered together to read the diary.

I have no interest in that diary.

I searched through all the books in that corner, but I couldn't find anything related to the secret arts of the demon race.

Unfortunately, we had no choice but to give up.

That being said, I would like to ask Alsterd if he has any leads.

After all, he seems to know everything.

In that case, should we take this book back with us?

Of course it's impossible...

However, you can just copy it down.

“Icarus, help me copy down this book, ‘About Rostina’.”

"Yes."

Icarus obediently began to copy.

You've worked hard, Icarus.

……

Icarus is copying.

I wait for Ariel and the others to finish reading the diary.

While waiting.

My gaze fell upon the Demon King Bedobé Toberta.

Before I came, Alsterd told me about it.

Try your best to get along with it.

But then again.

Why do we need to cultivate good relationships...?

Moreover, how do you build good relationships?

As far as I know, demons are generally a race that doesn't listen to people properly, especially the Demon King, who is the best of the worst.

That being said.

Since it's Alstered's request, it's best to give it a try.

Alsterd described how to communicate with it.

Simply write the words on a piece of paper.

So I took out the paper and pen I had prepared.

"Greetings, Your Majesty the Demon King. It's a pleasure to meet you. My name is Rudeus Grellat. This library is truly wonderful."

I wrote this text fluently.

And so, the giant slime also began to move its tentacles and write fluently...

As it was writing, it suddenly stopped moving.

An unusual atmosphere suddenly filled the space of the mortar and pestle.

How scary, how terrifying...

It gives you the feeling that it might attack at any moment.

When I thought so.

The Book Demon King's eyes have already turned this way.

My image was clearly reflected in the slime's enormous eyes.

Then, it extended a tentacle.

The tip of the tentacle was holding a piece of paper with writing on it.

"I am Bedobeta, the Demon King of the Sticky Clan. Welcome to my castle, human who possesses the Book of the Future."

It worked!

Speaking of which... what is the Book of the Future?

Do I have that kind of thing on me?

Never mind that for now.

I continued:

"It is a great honor to meet you, Your Majesty. We have come today to investigate a certain matter. Would you allow us to stay here for a while?"

"allow."

What a smooth communication!

I must say, as expected of a well-read and cultured person like myself, I speak with great logic.

He's much better than that idiot Atofi.

"Your Majesty, what do you mean by the Book of the Future you just mentioned?"

After I wrote it like this...

The Demon King quickly provided an answer.

"That book about the research on immortality magic, you obtained it from the future, right?"

"what……"

It turns out to be that one.

On my tenth birthday.

Lala appeared before me using time magic and handed me three crucial items.

One of them is the copying of immortality magic that I have been researching in my previous life.

I can't believe it even saw that book...

"Your book is very interesting, and many of the ideas in it are unheard of. Please continue to work hard on the next part, so that I can also feel happy."

"Yes, I will try my best to keep writing."

"I'm really looking forward to it."

After writing this sentence.

The Demon King Bedobee then retracted his tentacles and continued writing something.

Communication went very smoothly.

Well, let's just say it's a way of building good relationships, shall we?
