In Shihua's cognition, Zhang Zi'an is a super stingy and super rational person, and he can even calculate every phone bill charged to her clearly, how can he do meaningless things and waste money? His parents have passed away, but they still keep their former numbers unblocked, which is not in line with his personality!

Zhang Zi'an didn't know why she asked, so he nodded, "If you don't charge the phone bill, it will be shut down, and China Mobile is not charitable." ”

"So, not only have you been charging your phone bill, but you also charge their mobile phones every day?" Shihua asked, "Didn't you say that this is a commercial electricity use, and every time you pay for electricity, you will feel very distressed?"

Zhang Zi'an was speechless, "How stingy do you think of me?"

Shihua couldn't say what it was like in his heart, as if he had reacquainted himself with Zhang Zi'an, he not only kept the numbers of his deceased parents in his mobile phone contacts, but also recharged their numbers and charged their mobile phones, just like when they were alive, just like ...... It's as if they're not dead.

She always thought she was alone, but in fact he was also alone.

"Why are you looking at me like this?" Zhang Zi'an looked down at his pants to confirm that his crotch was also wet.

"Nothing. Shihua shook his hair, pulled his fingers, selected Weikang from the contact, and then dialed the phone, and when he heard the other party's answer, he handed the phone back to Zhang Zi'an, still staring at him tightly.

"Hey, Professor Wei, it's me, Zhang Zi'an. Zhang Zi'an was a little embarrassed by Shihua's staring, and paced out of the bathroom while talking on the phone.

"Oh, Xiao Zhang, what's the matter? It's about the expedition?"

Wei Kang's tone suddenly became nervous, he was worried that Zhang Zi'an suddenly proposed to withdraw from the expedition and no longer participate in the trip to Egypt, which would be a great loss to the expedition.

"No, it has nothing to do with that. In fact...... I want to borrow a scientific instrument from you, I don't know if it's convenient for you?" Zhang Zi'an said.

"What kind of instrument? Let's hear it, if it's an ordinary instrument that I can be the master of, it's fine, if it's too valuable, I don't have the right to borrow it, so I can only ask the leaders of the hospital......" Wei Kang stretched out his voice with reservations.

Zhang Zi'an said: "It shouldn't be a particularly expensive instrument, it's an underwater pickup, I don't know if you have it there?"

"Underwater pickups?" Wei Kang's voice paused, and then asked in surprise: "This instrument can be borrowed, but don't mind if I ask, why do you want to use this thing? The borrowed instrument needs to fill out a form, I need to know what your purpose is." ”

What he meant by this was that you still need underwater pickups to open a pet shop?

Zhang Zi'an explained: "Professor Wei, I recently opened a branch of the aquarium, and at the same time, I have also aroused some interest in whales, especially the sound of whales, which feels particularly melodious and mysterious, and I am fascinated as soon as I hear it...... Aren't there a lot of whales off the coast of our city now? I want to record some of them and play them on a loop in my aquarium, so that it can create a mysterious atmosphere under the sea. ”

"I can't see it, Xiao Zhang, your aesthetic style is quite high! Few young people of your age can calm down and listen to whale songs. Wei Kang's tone was both surprised and appreciative, not like sarcasm, "But the whale's song can be downloaded from the Internet ready-made, why do you want to record it yourself?"

Zhang Zi'an smiled: "Professor Wei, you shouldn't ask this...... You go to the field so hard, and you may not be able to discover new species as you wish, so why do you have to go again and again? Although I can download ready-made whale songs on the Internet, I still want to record them myself, and I hope to discover something different and new. ”

Wei Kang was silent for a moment, Zhang Zi'an thought that what he said made him angry, but he immediately slapped the table and exclaimed: "Okay! This is the spirit that scientific exploration should have! It seems that you are naturally suitable for this profession! Really don't consider coming to my graduate school?"

"Professor Wei, you're joking again!" Zhang Zi'an said hehe, he spoke completely to his liking, and he deliberately pleased Wei Kang in order to borrow the underwater pickup, how could he have any spirit of scientific exploration......

Wei Kang sighed, "Okay, I'll go talk to my colleagues who study marine life and see if they have any free underwater pickups...... By the way, how long are you going to borrow?"

"Maybe a few days...... I try to be as fast as I can. Zhang Zi'an was not sure if he would encounter a giant whale next time he went to the beach, so he could only relax his time.

"By the way, Professor Wei, you tell your colleague that I won't borrow it for nothing, and your colleague will get something in return. He added.

"No, you don't have to give money, this time it's my private loan, so you don't have to give money. ”

Wei Kang thought that he was going to pay the rent and said that he didn't have to pay, but Zhang Zi'an actually wanted to repay it in a special form - in the name of a private person, he gave a few of the ice anemones he raised and bred to the biology department of Binhai University and provided them for research.

Ice anemones are a new species that has just been discovered from under the Antarctic ice sheet in recent years, and so far people don't know what they do and how they root their delicate bodies in the ice. If the teachers and students of Binhai University can lead the world in solving the mystery of the ice anemone, and even discover a certain ingredient in the ice anemone that can be used in medicine, it may cause quite a stir, and then he will be honored, and it will be very convenient to borrow something in the future.

Zhang Zi'an does not have the corresponding knowledge and research instruments, and has no interest, the ice anemone is just an ornamental pet in his hands, it is better to share some of it for the benefit of science, and it can be regarded as making up for the favor he repeatedly owes to Weikang.

"It's not about paying, it's vulgar to talk about money, I want to give you some good things. He pretended to mysteriously hang Wei Kang's appetite.

Wei Kang was stunned when he heard this, thinking that Zhang Zi'an had finally figured it out and was willing to take out the original Egyptian cat to do research for him, but after thinking about it carefully, it didn't seem like it.

Although he repeatedly asked what it was, Zhang Zi'an never specified it, and planned to surprise him when the underwater pickups were returned.

Wei Kang hung up the phone first, went to borrow an instrument from a colleague, and then called Zhang Zi'an, saying that everything was going well, and there happened to be a spare one on his colleague's side.

The two agreed on a time and place to meet.

When the time came, Zhang Zi'an drove to Binhai University, filled out the corresponding rental form with the help of Weikang, and finally got the precious underwater pickup.

With this thing, it is possible to record and analyze the voice of the giant whale and unravel its mysteries.
