My name is Twenty-One.

My real surname is "Two"!

Two is two of one, one is one of two, and one is one of two.

The surname 贰 (liǎng), the name 壹 (yǐ), and the pass "B" also pass "Yi".

That is, the "two one" in the middle of "Wuji gives birth to Taiyi, Taiyi gives birth to two instruments, two instruments give birth to four elephants, and four elephants give birth to gossip".

And so on, my grandfather should be called "Wuji", my father should be called "Taiyi", my son should be called "Sixiang", and my grandson should be called "Bagua".

Well, it doesn't matter!

Importantly, a book that fell from the sky smashed my head!

......

Eryi, who looked confused, covered his head with a big bag and sat on the ground stupidly.

stared at the book not far in front of him, which was more than ten centimeters thick, more than thirty centimeters wide, and more than forty centimeters long...... Book?

Well, it does look like this book.

I don't know what material of dark red thick leather, wrapped around the front and back cover, which is a finger thick.

The polished and shiny brass corners have no title except for a gray-white turbid spar inlaid in the middle of the cover.

The second one looked up at the sky, there was no!

If you look around, the nearest building is also 800 meters away!

So the question is, where did this broken book come out of it and smashed his head?

Er Yi carefully groped for the big bag on his head, but accidentally touched the sore spot, gasped for air, and grinned in pain.

Looking at the blood stains on his hands, he should have just broken his scalp, and moved his neck again, making sure that there should be no big problem with his head.

Only then did the second one begin to rejoice that this strange book of unknown history fell.

It was the mere cover that slapped on his head, not the brass corner that looked dangerous.

The reason why the skin is broken is probably to blame on the spar inlaid on the cover.

The protruding hedron was in the shape of an irregular diamond, with slightly sharp edges that made contact with his scalp...... But now doesn't seem to be the time to think about that?

Eryi, whose head was dizzy, staggered up, only to feel that there were bursts of blackness in front of him, and countless golden little stars were flying in front of him like cheerful fireflies.

Er Yi gritted his teeth and got through this uncomfortable feeling, and then walked over and picked up this strange book that fell from the sky.

After carefully observing the surroundings again, to make sure that it was not someone playing a prank, or the accident of a falling object from a height, Er Yi vaguely felt that he might have encountered some mysterious incident!

To say that the heart is not square, hairy, and a little nervous, that is definitely a lie.

But as soon as the sun was shining in the daylight, this strange book that fell from the sky...... Let's call it "Book of Heaven" for short, after it fell, he just lay on the ground honestly, and there were no demons and monsters or supernatural events.

Second, coupled with the popularity brought by the large group of energetic students running and jumping on the sports field of this college, the second one is not so afraid, but more in his heart is some small expectations and full of curiosity.

Because how do you look at this opening, how do you feel like some kind of routine that is going to have a bloody adventure?

With a nervous and uneasy mood, Er Yi took a deep breath, and seeing that no one noticed himself in the corner of the sports field, he resolutely opened the cover of the "Book of Heaven...... Well, nothing happened!

There was not a single thunder in the sky, nor did Aladdin's lamp god appear.

The pages under the cover were bound from some kind of yellowish, slightly thicker old leather paper, but there was not a word on it!

Eryi was stunned and turned a few pages back, and even turned directly to the back, and sure enough, there was nothing!

What the heck?

Wordless Book of Heaven?

Or is this a blank notebook?

Thinking that he had opened the wrong way, he carefully flipped through it from beginning to end.

I also pinched the front and back covers, which were a finger thick, to make sure that there were no mezzanines inside, hiding martial arts cheats or treasure maps of the Pirate King.

After confirming it again and again, Eryi understood that this is a blank notebook with strange features!

Although the cover is a little peculiar, the material is a little rare, the whole is more exquisite, the origin is a little weirder, and it looks a little mysterious...... But it's meowing.,That's a little thicker.,Blank notebook!

"Walk you!"

Eryi threw the book in a hurry.

I thought I had encountered an adventure in an online novel!

He was nervous and looked forward to it for a long time, and his head was smashed with a big blood bag.

The scalp that was knocked out had several drops of blood, how much Nutrition Express do you have to drink to make up for it?

Huh?

Wait?

Eryi rubbed the blood stains on his fingers that had been dried up.

Isn't it true that all the strange things in the novel have to be recognized by blood and recognized? Maybe they haven't recognized the Lord yet, so they can't see the content?

He hurriedly farted again, ran over and picked up the "Book from Heaven".

endured the pain and touched the small wound on his head, stained a little blood on the gray-white turbid spar on the cover, and carefully applied it.

However, when the blood applied to the spar was all dried, nothing happened to the spar bloodsucking, the brilliance of the light, the appearance of the machine spirit, and the binding of the system.

"Is it because there isn't enough blood?"

Er Yi touched the small wound on his head suspiciously.

At this point, they were already scabbed, and when I looked at my fingers, I gave up decisively.

He's not a Naruto, he can't get out of his mouth when he bites his fingers, he's afraid of pain!

Er Yi could only reach out and wipe the dried blood stains on the turbid spar depressedly.

This "Book of Heaven" looks pretty good, and I'm going to take it back as a souvenir.

But after he wiped off the bloodstains, he inadvertently found that a faint streamer flashed faintly in the gray-white turbid crystal!

"Huh?"

"Works?"

Eryi's eyes lit up, and he held the "Book of Heaven" and observed it from various angles for a while, but he never found the streamer again.

"Is it dazzling?"

Eryi muttered depressedly.

I decided to go back and smear some red potion first, and then study this "Book of Heaven" carefully, otherwise the wound on my head would become inflamed.

Like moving bricks, Er Yi carried the heavy "Book of Heaven" back to the dormitory with great effort and threw it on his bed.

Then I rummaged through the cabinets, and from the cabinet of the dormitory boss Fat Tiger, who loves to play basketball, I took out a bottle of red potion and fumbled for it, and I also used two band-aids to put a stupid X on top of my head.

When I went to the bathroom, I carefully avoided the wound and cleaned up my personal hygiene.

After taking a bath, Er Yi climbed into his bed, hugged the "Book of Heaven" and studied it again.
