Zhang Zi'an dried his hair, talked to the customer for a few words, and asked Li Kun and Jiang Feifei to go back to the next door to take care of the business, and went up to the second floor by themselves.

The customer's whale watching offer is great, but if there's a moody whale on this side of the shallow water, God knows when it will suddenly appear next to the boat, and it will be a problem if the boat overturns and poses a danger to the customer.

He knocked on the door and waited a moment before entering the bathroom.

Shihua looked him up and down and asked, "Is the water on your body really sprayed by whales?"

"Well, I ran into that whale again, and it almost capsized the boat. Zhang Zi'an took out the things in his pocket and threw the wet clothes into the laundry basket, planning to save up and wash them together.

"What's the matter? you didn't give it my song?" Shihua frowned suspiciously, she didn't dare to assert anything else, but she was very confident in her singing, and she never had a problem communicating with the whale with her singing.

"Of course I put it, but it didn't seem to work, and it was counterproductive. Zhang Zi'an replied truthfully, "The strange thing is that your song is effective for the minke whale, but not for the giant whale, do you know what's going on?"

Shihua blinked innocently, except for the white whale that was white, she couldn't tell the other whale species, even if he said it was a minke whale or something, she didn't know what kind of whale it was.

Zhang Zi'an told her the most important story of going to sea today, and then concluded: "At present, your song has only been played to two kinds of whales, one is effective and the other is ineffective, I also want to find more whales to increase samples, but unfortunately I can't find it." The problem now is that there are only two possibilities for this – either there's a flaw in your singing or there's something wrong with the whale. Which one do you think?"

"No way! My singing voice is absolutely fine! You must be opening in the wrong position!" She was afraid that he would blame, and quickly shirked the responsibility in advance.

Zhang Zi'an put his hand on his forehead, "What if the posture problem is temporarily ruled out?"

"That'...... That's the whale has a problem! Yes, it's probably deaf!" Shihua rolled his eyes and suddenly said, "People are deaf, and whales are also deaf!"

After finishing speaking, she was still complacent, looking like "I'm so smart".

Zhang Zi'an: "...... There may be deaf people in the whale, but this giant whale probably can't be, because I think it was attracted to it because it heard your song. ”

Shihua was stunned for a moment, "Impossible! After hearing my singing, it is impossible for it to attack you again!"

"I mean, it did hear you, but for some reason that we don't know at the moment, it didn't understand or didn't understand your singing. Do you think this is possible?" Zhang Zi'an patiently explained, "Remember I asked you, right? Can all cetaceans understand your singing? If not, will there be a misunderstanding?"

If it had been before, Shihua would have answered this question in the affirmative without thinking, but now she is not so sure, because if the whale is okay, then the problem lies in her singing itself, and she does not want to admit it anyway.

She struggled to remember, and said, "Most whales should be able to understand it, right? at least...... Whales near Germany can understand it, I can learn it when I hear their songs, and if I can't hear them, I can't do anything. When I arrived in Marina City, I could understand the whale song in the nearby sea...... Maybe the whale is from the remote countryside!"

The low-frequency sound waves of whales can travel far away, but they are not infinite, depending on the sea conditions, they can travel thousands of kilometers at most, and Shihua, who was born near northern Europe, can only hear whale songs in that range.

"Then can you hear the voice of the giant whale now?" Zhang Zi'an asked again.

"No, there are so many whales in the neighborhood right now, it's like a thousand ducks calling, and I can't tell who's who. I usually have to try not to listen to those sounds, and use those sounds as background sounds of wind and rain, otherwise I won't be able to hear you. Shihua shook his head.

I see...... Zhang Zi'an thought about it, it is indeed very hard to hear too much, and even some sounds that you don't want to hear can be heard, if it were an ordinary person, you might have gone crazy a long time ago, and it is also a loss that Shihua's brain is a tendon.

Although the number of cetaceans has decreased dramatically, there are thousands of whales within a radius of thousands of kilometers, including giant whales, just like thousands of people talking at the same time, and trying to pick out a specific one is tantamount to looking for a needle in a haystack.

"Understood, then I'll change the question - if you hear the song of the giant whale, can you understand and try to talk to it?" Zhang Zi'an threw out another question that had been prepared in advance.

"Uh......" Shihua scratched his hair in distress and said uncertainly, "I didn't learn it deliberately, I learned it unconsciously...... I guess I can. ”

"Well, then I'll figure out how to get the whale's song. Zhang Zi'an nodded, indicating that he had no problem.

"Wait a minute!"

He was about to leave the bathroom when he was stopped by Shihua.

"How are you going to get the whale's song?" Shihua noticed the waterproof bag pressed under his phone, "Do you want to put your phone in the water to record?"

"Of course not. Waterproof bags can only prevent daily splashing, and if you really put it underwater, it may not be waterproof...... In addition, even if the waterproof bag can be waterproof, it will also hinder the transmission of sound and distort the sound. Zhang Zian shook his head and said.

"That ......"

"If you want to record underwater, you can only find professional equipment, which is a high-precision recording device called 'underwater pickup'. He further explained.

"Oh haha, it turned out to be an underwater pickup...... Shihua didn't know how to pretend to understand, "This thing can also be bought online, just like you buy a boat online?"

"You can't buy this from the Internet, not even the almighty Taobao. Zhang Zi'an shrugged regretfully.

"What then?" she asked again.

"But I know a guy who is an associate professor in the biology department of Coastal University, and he often goes on field trips or something, and I think he should have it there. I'm going to call him later and ask if he can borrow it for me. Zhang Zi'an is quite sure that there must be this kind of professional equipment in the dignified biology department, but he is not sure if he can lend it.

"I ...... I'll call! I haven't made a phone call yet!" Shihua begged with great interest.

It doesn't matter, whoever fights is the same, anyway, now I have to ask her, just to meet her little wish.

Zhang Zi'an happily agreed to her request and unlocked the screen of the mobile phone, revealing the interface of the live broadcast app that had not yet been closed.
