Um?

Musashino looked in disbelief:

"Don't you know about the things in the prehistoric era?"

In his opinion, the information reserves of "Book of Forgotten" should cover older things.

Crazy-

It almost shook the pages:

"Absolutely none. Those are my blind spots in knowledge, even Laplace's blind spots."

"Even Laplace doesn't know?"

"Of course, He is a god born at the same time as the Source, and it is only more than four thousand years ago. He has no way to calculate the older things."

When Musashino heard this, he was a little surprised:

Then I, a time traveler in the 2000th AD...

In many ways, it actually knows more than Laplace.

Although Musashino is a science student, he thinks he is still good at history.

"good."

He first tried to say a message:

"In the mid-20th century, humans at that time learned the power of using nuclear power for the first time..."

"The Book of Forgotten" listened quietly to this history, and his emotions gradually became excited.

Swish swish swish swish ~

Line after line of handwriting appeared on the sheepskin scroll, and it obviously remembered quite well.

"...As the end of that meeting, the human world temporarily maintained peace and stability, and the power of the nuclear power did not spread unlimitedly."

About ten minutes later, Musashino ended the story.

These are the contents of junior high school history textbooks.

In his time when he was in school, it was completely well-known.

But after thousands of years, it has long become an absolute secret that even the 10th-level seal objects desire to know.

"Very good!"

"The Book of Forgotten" was excited to walk around the air:

"Himmer~"

Then came a loud burp.

Musashino could see that this book is in a good mood now and should meet the standards required by the law.

"I've told you that next is the time to fulfill your promise, let my companions leave this twist of history-reality."

"Wait a minute!"

"The Book of Forgotten" quickly said:

"Forehead.

"Laplace's rank is too high after all. If you want to steal me from Him, you still need... to... a little more knowledge."

It looked at Musashino frowned and added again:

"It's really just a little more!"

Musashino raised his eyebrows:

"I suddenly thought of a very critical question...

"Since I'm talking about what you haven't recorded, how do you judge the authenticity? Do you even include the random fabrications?"

Ah this.

"Book of Forgotten" thought about it and answered:

"Actually, I can't explain this clearly.

“I seem to have accommodated all the information since the birth of this world, but unfortunately it is missing for some reason, so I am collecting history everywhere now.

"Essentially, it's about retrieving what I've lost!"

That feeling is strange.

It's like a groove with a specific shape. Although it may be empty at the moment, as long as the building blocks are embedded, it will know whether it is tightly fit.

Musashino was confused when he heard it:

"This is OK?"

Record all the information since the birth of the world?!

What is this book?

Planetary-level fossils?

And it is also a fossil that can be recorded dynamically.

"A planetary fossil that can dynamically record information"

——This is Musashino's preliminary guess about the origin of "The Book of Forgotten". Of course, it cannot be verified yet. After all, I don't know who I am in this book.

"So, is there any?"

The Book of Forgotten is urgently urging.

"Wait."

Musashino thought for a while:

This book claims to record since the birth of the world, not since the birth of human beings.

That is the history of the earth ~

That's so long!

The history of the earth is billions of years.

It’s better to say something that is so outrageous that it’s so long and see if this book can react:

"Listen.

"In the early days of the birth of this planet, it was once impacted by planets, and a large amount of scattered matter gathered in orbit, and finally formed...

"Moon."

This is already a hypothesis in the field of astronomy.

It involves 4.5 billion years ago.

Squeak-

"The Book of Forgotten" suddenly stopped when he heard this, as if it was a crash.

"Um?"

Musashino tried to contact it: "How, is this historical knowledge considered true and credible?"

Bang!

As soon as he finished speaking, the Book of Forgotten exploded.

A large amount of text inside escaped and then regrouped again, and it took a full ten minutes to regroup into a book.

"It's true!"

It was so excited that it screamed:

"Not only is it true, the knowledge you just said is enough to provide me with the energy needed for a hundred years to operate normally!"

This is OK?

Musashino just said it casually half-jokingly.

"The Book of Forgotten" is probably more confusing than imagined...

"Hey, do you really know nothing about your origin?"

He asked.

After receiving two knowledge in a row, the attitude of "Book of Forgotten" turned 180 degrees and answered patiently:

"Dear Lord Good Law Heaven...

"cough!

"I am using honorific words, absolutely nothing to mean you!" It also emphasized.

"Sir, I only remember... I seem to come from the center of the earth."
