Sometimes when Zhang Zian dreams in the past few days, he can dream of the nameless German headland, the densely packed strange marine creatures, and even create even more weird creatures in his dreams.

In the unfathomable ocean, there are many creatures that are enough to challenge the boundaries of human imagination. Once these creatures are attracted by Shihua's appearance in Binhai City, it is hard to imagine what the consequences will be. Evil sharks, giant whales, and king squid gather at the port, which may cause a big commotion.

It's comparable to a weapon of mass destruction!

Therefore, Zhang Zian is very concerned about the answer to this question.

Shihua shook her head in confusion, saying that she didn't know.

Obviously, her ability to summon marine creatures is one of her passive skills. The root cause is probably the sentence in her characteristic "It makes people think and come to sleep with her." Because she is too beautiful, many marine creatures are unknowingly attracted to her and want to sleep with her.

Zhang Zi'an scratched his head, what should I do?

Shihua had no idea of ​​the seriousness of the matter and hummed his own children's songs and played with the little yellow duck.

"One little yellow duck and two little yellow ducks, swam to see Oppa. Oppa is not at home, so he comes back to find Shihua..."

"quack!"

Richard flew up from downstairs and heard him talking, and he interrupted, "You idiot! Have you forgotten? She didn't sing a song at that time and sang the white whale away! In my opinion, you should have brought the white whale back and rode it to see the island actress you are thinking about. It just happened to be the saying that Fusang will ride a whale this day, and when will Zi'an turn into a crane?"

Zhang Zi'an pinched the soap and threw it at it, "Your uncle! This is a fucking elegiac couplet!"

"Gaga!" Richard hurriedly avoided, flew downstairs to tease other elves, and could hear its noisy sound from the stairwell from afar, "Roar up and throw soap, lean over and offer chrysanthemums! I finally matched this solitary couplet of the ages!"

As soon as it left, the second floor suddenly became quiet.

Zhang Zi'an thought about it carefully and said it was quite reasonable. Of course, it did not mean that he leaned over to offer chrysanthemums, but that the white whale left the coast and returned to the deep sea after listening to Shihua's singing. This shows that although she could not control the marine creatures and let them not follow, she could let them leave.

"Shihua, when you were on the coast of Germany, you sang a song with the beluga whale, right? Then the beluga whale left?" he asked.

"Yeah." She nodded absent-mindedly.

"Then can you do the same and let the marine creatures approaching Binhai City leave?"

She nodded and shook her head, "It's too far away to hear it."

"That means that if marine life is too far away, you won't be able to hear your singing?" he asked again.

"Um."

Well, he didn't take this into consideration.

If Shihua can leave the pet store and go to the sea or to sing at the beach, it will be fine, but she cannot leave the pet store for the time being...

How about recording her singing and then playing it at the beach?

But this doesn't work. Even if you go to the beach, how far can it be transmitted?

Zhang Zian couldn't think of any other way to bring this mermaid to Binhai City, but he didn't expect it to cause such a big trouble.

He was about to go downstairs for a walk, and maybe he could figure out a solution, but then he heard Shihua murmuring himself: "If Oppa heard my singing, would he come here to find me..."

"Impossible." Zhang Zian gave up her idea as soon as possible, "Isn't your Oppa in South Korea? It's hundreds of kilometers away from South Korea!"

She pouted, "Hundreds of kilometers? How far is hundreds of kilometers? But I clearly heard the whales in that direction crying."

As she said that, she raised one arm and pointed to the northeast direction.

Huh?

Zhang Zian was stunned and looked in the direction she pointed, but could only see the bathroom wall.

"Wait, what did you mean just now?" he asked. "You hear whales crying? From here, can you hear whales crying? Why can't I hear?"

"Because you are a fool! Didn't the bird call you an idiot just now?" She grimaced at him.

Zhang Zian was not in the mood to joke with her and asked seriously: "Shihua, please answer me seriously, can you hear the whale's voice now?"

Shihua rolled his eyes cunningly, "Is there any reward for answering?"

"Yes, of course, there are." He replied casually.

"What is the reward? I want to watch TV!" she said excitedly.

Zhang Zian thought for a while, "I can promise you to shorten your waiting time, but it is impossible to watch TV immediately, because there is only one TV in my house, and now Mr. Tea is watching. You see, Mr. Tea is old, so we should respect the elderly and love the young, right?"

"It's the brown old cat that lets me dress?" she asked childishly.

"Yes, its name is Laocha. You can call it Laocha like me." Zhang Zian replied.

She was reluctant, but she reluctantly agreed, "Then do what you say?"

"Of course, count." He agreed, "Now answer my question."

"You can hear it, not only the whales over there, but also the whales over there, over there, over there, over there, over there, over there and over there!" She said, waving her fingers around, almost covering nearly 180 degrees from 2 o'clock to 7 o'clock. She looked very serious, not like a joke.

Zhang Zian understood.

Human voices span 2 to 3 octaves, while whales span 8 octaves, they can make high-frequency scales that are inaudible from human ears to almost piercing the eardrums.

The speed of sound propagation in the air at room temperature is 340 meters per second, while the speed of propagation in the sea is as high as 1500 meters per second.

Whales use their low-frequency sound waves for ultra-long-distance communication, and can even send simple signals to whales thousands of kilometers away.

Low-frequency sound waves alone are not enough to cross such a long distance. Whales can do this because there are "deep sound channels" in various oceans. The so-called deep sound channels are actually water layers with different density, and have the characteristics of guiding sound waves due to the density differences between water layers. However, this deep sound channel is only open to low-frequency sound waves, which is a unique benefit for whales.

The sound signals of whales are very complex, and the sounds made by different species of whales are also different. Even the same type of whales will have a unique regional accent because they live in different regions, just like humans.

They sing endlessly in the sea, are they talking to each other, or humming small songs with entertainment? Despite doing a lot of research in recent years, humans still have no way to know.

Shihua said that she could hear the sound of whales and pointed to four directions: Bohai Sea, Yellow Sea, East Sea and South China Sea. This means that she could hear the low-frequency sound waves emitted by whales in the surrounding sea areas. This may be a privilege as an elves.

He just figured out this question and immediately asked in surprise: "Shihua, why are the whale crying?"

"I don't know..." She shook her head in confusion, "I only know they are crying."

Although low-frequency sound waves propagate very far, they carry extremely low information, only 1 bit per second. In contrast, each word carries 10 bits of information when humans speak.

So Shihua did not lie or deliberately shirk responsibility. Instead, she could only hear the whale crying, but she could not know why she cried.

Maybe if you wait a while, new information will come.

Sure enough, she listened again and said, "The sound is very messy. They seem to be running away, as if they are being chased, and being killed..."

Speaking of this, she looked frightened, and her fair and smooth skin had a layer of fine goose bumps due to trembling.

"Forget it, stop listening, I understand." Zhang Zian interrupted.

She stared at him half open, looking forward to his explanation.
