The magician of the fairy tale world

Rhine chatted with the mermaids who were watching very smoothly.

This "strange creature without a tail" briefly explained where they came from.

After asking a few simple questions and confirming that the general situation of the underwater kingdom was not much different from the book, he praised the power of the Sea King, the beauty of the Sea King's palace and garden, and the wisdom of the Sea King's mother "Grandmother", and the beauty and nobility of the mermaid princesses.

He was familiar with the place, not like a visitor who had just set foot in the sea kingdom for the first time, but like a guide who often traveled to the sea kingdom.

In a short while, the mermaids became quite familiar with Rhine.

They talked about everything. Rhine acted like the knowledgeable magicians in the story, answering the mermaids' strange questions about the world on the ground one by one.

For example, a mermaid asked:

"Why can the fish in your upper world swim even when they are not in the water?"

Aurora was just confused by this.

There are no fish in the human world that "can swim even when they are not in the water"!

Rhine immediately told the little mermaid:

"In the human world, we don't call those creatures fish - although they do fly over our heads like the fish here, but we call them 'birds'. Birds can fly because they have a pair of wings. Wings are to the air like fish tails and fins are to the water."

Aurora was stunned and looked at Rhine suspiciously.

No, how do you know she is asking about birds?

Another little mermaid asked:

"I heard from friends who have been to the sea that in your world, the moon and stars are smaller but brighter than ours. Why is that?

"Will the moon and stars condense when they see you humans?"

What? The stars and moons in the sea world are bigger than those in the human world? Wait, are there stars and moons in the sea world? Aren't they all in the sky? Aurora was completely confused.

Rhine smiled and patiently explained to the mermaid:

"This is an optical illusion caused by the refraction of light. In other words, your eyes deceive you. ”

When watching the stars and the moon in the shallow sea, the light they emit will be much fainter, but through a layer of water, the moon in the eyes of mermaids is much larger than that in human eyes! (Note 1)

He even took out a pen and paper on the spot, drew the path of light, the angle of incidence and the angle of refraction, and explained the changes caused by the light entering the water, which was used to illustrate the difference between the world in the eyes of mermaids and humans, and the many problems caused by this difference in perspective.

Aurora barely understood the physics knowledge explained by Rhine. She was amazed at the teacher's rich knowledge and felt that the world actually hid such deep secrets - seeing is not necessarily true.

But the mermaids who had never been to school were very confused.

They just kept praising it, thinking that although they couldn't understand it, it was very powerful, and it must be a kind of profound knowledge.

The human boy who talked to them must be a profound scholar from the upper world!

"It turns out that although we who live in the sea don't understand the humans in the upper world, humans understand us so well!"

"I thought we didn't have much contact with humans. Humans know nothing about us, His Majesty the Sea King, the kingdom in the sea, and the world in our eyes! "

"Humans have profound and extensive knowledge. Although I can't understand it, it seems very powerful."

The mermaids sighed after chatting with Rhine.

Aurora saw this scene and loudly refuted in her heart:

"No, no, it's not like that! Teachers can't be used as examples for humans!

"Most humans know nothing about the kingdom of mermaids, and they won't study such wonderful knowledge and explore the differences between the perspectives of mermaids and humans."

Turning her head to look at Rhine who was talking happily with the mermaids, Aurora was very confused.

Teacher, is this really your first time in the kingdom of the sea?

Rhine seemed to know Aurora's confusion, and explained while recalling:

"I have read a novel before. The protagonist of the novel is a race living in the sea. It provides marine creatures with a perspective and way of looking at the world, which is different from our human perspective.

"I just put myself in the perspective of the mermaids and use their way to understand their problems.

"In the novel, the author compares the school of fish to birds - in fact, this is similar. Just as humans can see flocks of birds of different colors flying by when they look up, mermaids can also see flying birds when they look up.

"The novel also says that the moon seen by sea creatures in the shallow sea is much larger than that seen by humans!

"Many years ago, when I first read this paragraph, I was still very surprised. I used my knowledge to draw the path of light and studied it for a long time before I was sure that the author had not made any mistakes."

No mistakes in one post, one content, one 6, one 9, one book, one forum!

When the boy said this, he couldn't help laughing, and his eyes were full of memories and reluctance. This reminded him of the years before he came to this continent.

After the mermaids’ questions were answered, they curiously asked this “new friend without a tail”:

“Humans on earth, why did you come to this sea?”

Rhine took the opportunity to tell the purpose of his visit:

“We are here to find a sea witch, a sea witch who is proficient in black magic. We want to ask her for a small favor. You must know where she is?”

When the little mermaids heard the purpose of the two humans’ visit, their faces suddenly changed, and they were extremely suspicious:

“No way?”

"You're here to find the sea witch!"

"Is there anyone who dares to find her?"

"We mermaids in the sea don't dare to find her! How dare humans on earth be so bold?"

"Don't go, she's a scary guy who's proficient in black magic. Nothing good will come of going to her for help."

"..."

Note 1: The celestial bodies seen by mermaids in the water are bigger. Anyway, that's what Andersen said. I spent 10 seconds to simply make up the refraction diagram in my mind, and it seems to be like this. If there is any mistake, it's Andersen's fault.
