Zhang Zi'an blew his hair dry, 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 to the second floor by himself.

The customer's whale watching proposal is pretty good, but if there is a moody giant whale on the shallow sea, it's a different matter. God knows when it will suddenly appear on the side of the ship. If the boat overturns, it will be troublesome.

He knocked on the door and then entered the bathroom after a while.

Shihua looked him up and down and asked, "Is the water on you really sprayed by a whale?"

"Well, I met that giant whale again, and it almost overturned the boat." Zhang Zi'an took out the things in his pocket, threw the wet clothes into the laundry basket, and planned to save too much to wash together.

"What's going on? Didn't you give it my song?" Shihua frowned suspiciously. She didn't dare to assert anything else, but she was very confident in her singing. She never encountered any problems when communicating with the whale with the song.

"Of course I let it go, but it seems to have no effect and it has a counterproductive effect." Zhang Zian replied truthfully, "What's strange is that your singing is effective for the minky whale, but it's not effective for the giant whale. Do you know what's going on?"

Shihua blinked innocently. Except for the white whale, she couldn't tell the difference between other whales. Even if he said it was a minky whale or something, she didn't know which kind of whale it was.

Zhang Zi'an told her the important story of going to sea today, and then concluded: "At present, your singing has only been played with two types of whales. One is effective and the other is ineffective. I also want to find a few more whales to add samples, but unfortunately I can't find them. The problem now is that there are only two possible things in this matter, either there are flaws in your singing or there is a problem with the whale. Which one do you think is?"

"Impossible! My singing is absolutely fine! It must be that you opened the wrong way!" She was afraid that he would blame him, so she quickly shirked the responsibility in advance.

Zhang Zi'an held his forehead with his hands, "What if the posture problem is temporarily ruled out?"

"Then...that's the whale has a problem! Yes! It's probably a deaf!" Shihua rolled his eyes and said as if he suddenly realized: "People have deaf people, whales have deaf people!"

After saying that, she was complacent and looked like "I'm so smart".

Zhang Zian: "...There may be deaf people in the whale, but this giant whale should not be deaf people, because I think it is attracted by it because of hearing your singing."

Shihua was stunned, "Impossible! After hearing my singing, it will not be able to attack you again!"

"I mean, it did hear your singing, but for some reasons we don't know at the moment, it didn't understand or understand your singing. Do you think there is such a possibility?" Zhang Zi'an explained patiently, "Remember I asked you? Do all cetaceans understand your singing? If you don't understand, will there be misunderstandings?"

If it were the past, Shihua would give a positive answer to this question without thinking, but now she is not so sure, because if the giant whale is fine, the problem lies in her singing, and she doesn't want to admit it anyway.

She tried hard to recall and said, "Most whales should be able to understand? At least... whales near Germany can understand. I can learn when I hear their singing. If I can't hear it, there is no way. After arriving in Binhai City, I can also understand the whales in the nearby sea... Maybe that giant whale is from a remote countryside!"

The low-frequency sound waves of whales can travel far, but they are not infinitely far. They can travel up to thousands of kilometers depending on the sea water conditions. Shihua, born near Nordic, can only hear whale songs within that range.

"Then can you hear the sound of that giant whale now?" Zhang Zian asked again.

"No, there are too many whales nearby now, just like a thousand ducks shouting. I can't tell who is who. I can only try hard not to listen, and treat those sounds as backgrounds such as wind and rain, otherwise I will not be able to hear you." Shihua shook his head and said.

So that's it... Zhang Zi'an thought about it. It's really hard to have a wide range of hearing. Even some sounds you don't want to hear can be heard. If it were an ordinary person, he might have been crazy long ago, and it's a blessing that Shihua's mind is stubborn.

Although the number of cetaceans has decreased significantly now, within a range of thousands of kilometers, there are probably thousands of whales, including giant whales. Just like thousands of people talking at the same time, trying to select a specific one from them is tantamount to looking for a needle in a haystack.

"I understand, then I'll change the question. If you hear the singing of the giant whale, can you understand and try to talk to it?" Zhang Zi'an raised another question prepared in advance.

"Uh..." Shihua scratched his hair in distress and said uncertainly: "I haven't learned it deliberately, I've learned it unknowingly... Maybe it can."

"Okay, then I'll find a way to get the singing of the whale." Zhang Zi'an nodded and said that he was fine.

"Wait a moment!"

He was about to leave the bathroom when Shihua called out.

"How are you planning to get the giant whale singing?" Shihua noticed the waterproof bag pressed under his phone, "Do you want to put your phone in the water to record it?"

"Of course not. The waterproof bag can only prevent daily splashing. If it is really put under water, it may not be waterproof... Besides, even if the waterproof bag can have a waterproof effect, it will hinder the spread of sound and cause distortion of the sound. If it is recorded, it is equivalent to recording in vain." Zhang Zian shook his head and said.

"That……"

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

"Oh haha, it turns out to be an underwater pickup..." Shihua pretended to understand if he didn't know, "Can this thing be bought online? Just like you buy a boat online?"

"This one can't be bought online, not even on Taobao." Zhang Zi'an shrugged regretfully.

"What should I do?" she asked again.

"But I know a person who is an associate professor in the Department of Biology at Binhai University. He often goes to the field for inspections. I think he should have it. I plan to call him later and ask him if he can lend it to me for use." Zhang Zian was quite sure that there must be such professional equipment in the Department of Biology, but he was not sure if he could borrow it.

"I...I'll call! I haven't called yet!" Shihua begged excitedly.

It doesn't matter. It's the same for everyone to fight. Anyway, I have something to ask for her now, and it just satisfies her small wish.

Zhang Zian happily agreed to her request and unlocked the mobile phone screen, but revealed the live broadcast app interface that had not been closed yet.
