Ash tilted her head, proud because she felt that her answer would be subversive and at the same time correct.

Aren't we just living on Earth?

"Oh, Ash thinks it's a ball."

However, the teacher did not treat Ash's answer any special way, after all, children's whimsical ideas are always so wild.

"Teacher, really, really a ball, I can prove it!"

Ash's attitude was naturally very unhappy, because it was a look that treated her the same as the four or five-year-old children around her, and as a person who had lived a double-digit year in the last world, it could be said that it was an unbearable insult for Ash.

So Ash jumped on the seat and announced it loudly.

This behavior can be said to be very eye-catching, and at the same time, alas, I also understand and forgive this little fool Ash, who has no golden finger, and is now depressed only in his brain, and proudly despises the natives of the other world on these common senses, and especially, the helplessness to separate himself from a bunch of little children.

"Ah, Ash, get off the table first, it's too dangerous! And then, okay, so tell me how you're going to prove it."

Seeing Ash naughtily standing on the table, the teacher was worried and had a headache, and finally couldn't, walked up to Ash, and said so, at the same time, he also wanted to prevent Ash, a little naughty little naughty, from running to the table again.

After all, a four- or five-year-old baby is so skinny.

"Uh, ah, that, uh, ahem, yes, yes, I'm going to prove, um, that.

Yes, teacher, you see, from the seashore you see a sailboat coming from a distance, you see the mast first, then the hull. From the seaside, I saw the sailboat sailing into the distance, and the hull disappeared first, and the mast disappeared later.

Doesn't this prove that we are living on the same ball, after all, if it is flat, then the mast and the hull should be seen together, right? ”

Seeing that the teacher actually came seriously to ask himself to prove it, Ash was slightly stunned, after all, the emotions came quickly, and the mouth was fast, saying that he wanted to prove it, but his brain still had to use some time to recall and recall those long-ago knowledge memories.

"Oh? Sailboat, well, then, Ash, do you have any other way to prove it? ”

The teacher did smile inexplicably, and then asked Ash.

"Huh? Don't, somehow, well, yes, yes, and, there's!

Teacher, the lunar eclipse, that is the lunar eclipse, isn't the shadow round? And then, yes, if we have a ship, and the boat keeps going in one direction, then it's going to go around in a circle and come back to where it was, and there's that, and that's "

Ash has a little headache and a little regret for writing, after all, it is really not that simple to prove that the earth is a ball, and Ash is not such a genius or social elite.

"Well, that's, yes, that's the case anyway, teacher, this ball is the sun, this ball is the moon, this ball is where we are, the moon revolves around our ball, we revolve around the sun"

Feeling cocooned, Ash scratched himself up, and looked at the pair of shiny eyes around him (Ash's previous actions had managed to attract everyone's attention), and Ash's forehead appeared with drops of sweat that didn't exist.

-------------------------------------------------

In the midst of the entanglement, Ash directly grabbed a piece of paper, and then crumpled it into three balls, just to see how the earth, the sun, and the moon, the solar system, and the earth-moon system, rotated.

Xu was in a panic, or a ball made of paper to use as a world, Ash looked a little funny, and the children around him laughed confusedly and happily.

Alas, the dignity of the traverser, it turns out that Ash, after all, she is not a professional.

"Haha"

"Hehe, Ash's idea is interesting."

The teacher touched Ash's head as if to encourage Ash to keep this innocent and funny thought, and then turned and walked onto the podium.

"So, teacher, do we live on the same ball?"

"Yes, yes, if the teacher is a ball, if it is underneath, won't it fall?"

"Now, teacher, we don't live on that ugly paper ball that Ash made, we live on a beautiful, shiny crystal ball, right?"

As for children, curiosity and desire for knowledge are actually very strong, and by the way, they will also add their unmalicious self-preferences.

“…”

[Ah, uhhaha, ball, or crystal ball, ahh

Listening to the words of these elementary school students, Ash was a little confused, and blushed a little, a blush of shame.

So, it's really not so simple to prove, our world, all mankind has taken hundreds of years to understand it.

"Ah, everyone, be quiet, the question of whether we live on the same ball, well, then let's start with the 'evidence' that Ash said, and let's judge for ourselves."

"Look, this is a transparent glass ball, the first proof that Ash said, the hull and mast of the ship are not at the same time, well, teacher, let's zoom in on this, let's see how things around you look through this glass ball, will there be some distortion? And our eyes, the eyeballs are actually spherical, so why don't the hull and mast appear at the same time, do you understand? ”

The teacher waved his hand, and then a glass ball floated out of thin air, and then there was a light and shadow behind the teacher, like, well, like a screen, and there was a picture on it, well, a picture of the structure of the human eye and a picture of sight.

These are two little magics, the invisible mage's hand, and the visible projection magic.

"Got it!!"

Magical things, gorgeous light and shadow, children's attention is naturally highly concentrated and excited.

"Then, you see, a circle and a straight line, it is impossible to fit in parallel between them, right, so, in fact, the great supergod Magister, Magellan did a small experiment, extended a straight branch by a kilometer, and then he found that the distance between the head and tail of the branch and the ground is the same, so, little Ash, at least within a kilometer distance, our world should not be a ball"

The teacher smiled at Ash, then waved his hand again, canceled the spell, and continued.

"So, don't you think it's funny, everyone?"

"Interesting!"

"Teacher, it's a ball Ash and there is other evidence!"

"Ah, yes, but as for the lunar eclipse, and the question of the sun, this involves the theory of magical tides"

"Eh, what's that, Sensei!"

"So, teacher, are we living on a ball?"

"Well, this case, when you take the advanced magic basic theory class, you will naturally understand, and whether we live on the same ball, this requires you to study hard and explore by yourself, so, okay, please take out your own textbook, open page 54, we will officially start the course of the new unit, the basic elements of the world, only by understanding this, can you have a basic advanced course."

The teacher clapped her hands, and after successfully getting the children's attention to focus, she was going to see what was going to be a bit boring about the formal course content.

This method of hanging people's appetite is actually very suitable for children, and if you are itchy in your heart, you have to sit up straight and listen carefully.

As for our little Ash, her face is a little sluggish at the moment, after all, she has heard of magic, but it is the first time she has seen magic being used.

[Hawkers,It's too.,There's magic.,It's not strange if it's a ball.,Uh-hehe,Ahaha]

Ash twitched the corners of her mouth slightly, complaining in her heart, similarly, she was also a little frightened, since this world is not a ball anymore, then, she does not have any strong strength, perhaps, she should not be so arrogant that she thinks she is a genius.
