In the '76' Special Equipment Laboratory, Lin Shiqun, Ding Mo Village, Asano Ichiro and others were all there.

In the tape recorder, the voice of a young woman was heard. She could hear a little nervous and her sentences were urged, but it was quite coherent and her thoughts were clear. She should have been read according to a written word.

"Mr. Asano, can you confirm that the sound in the recording tape of Secretary Shen took it back is Miss Haruko Akagi?" After listening to this recording that was less than a minute, Lin Shiqun asked Ichiro Asano.

"The sound should sound Haruko's, but this is a tape. Who knows if this was recorded by them in advance?" Asano Ichiro nodded.

"Consultant Asano, how should we make a decision?" Ding Mocun asked.

"Yes, it's related to Miss Haruko's life safety. We must give the other party an answer immediately." Lin Shiqun echoed, "Asano, your judgment is crucial to us."

"They kidnapped Haruko just to exchange hostages for Jansen, and they should not hurt her. Miss Haruko is just an ordinary Japanese girl." Ling Zhijiang said.

If it were an ordinary Japanese woman, Ichiro Asano would not stand here, and he would take such a great risk with Lin Shiqun and others to let the resumption of assassination of Ji Yunqing.

"They do not have the motivation to hurt Haruko's life, which is certain, but once the hostages are exchanged, we will lose." Asano Ichiro said.

"Asano, for Miss Haruko's safety, there is nothing we can do about it." Lin Shiqun said, we can all understand.

"Okay, I agree to exchange hostages. If the Ji family knows it in the future, Asano will take the blame!" Asano Ichiro stood attentively and bowed deeply, "Please beg you all, please be sure to ensure Haruko's safety."

"Don't worry, Consultant Asano, we will do our best to rescue Miss Haruko." Ding Mocun said.

"Lu Wenying passed the message that they also need to confirm whether Jensen is alive and whether his life is guaranteed?" said Chen Xinlan, secretary of Ding Mo Village.

"We also asked Jansen to record a passage, wouldn't it be over for them?"

"Yes, it's not polite to come but not come."

...

Extraordinary Photo Studio.

"Team leader, it's trouble now. The '76' number also made a recording to send to us, but none of us knew Jansen, and we had never heard of his voice, so we couldn't tell the truth or false." Cao Bin called Tang Jin from the police station to his studio with a phone call.

"What?" Tang Jin frowned into the word "chuan" when he heard this.

"Ding Songqiao and the others thought of a solution, which was to invite Lu Wenying over and listen to her. Her own man's voice should be able to be heard. However, Lu Wenying is now being monitored by No. 76 and her phone is also monitored. Even if they want to identify it on the phone, they may be found by No. 76 following the clues. So, they dare not act rashly and want to ask us what we can do?" Cao Bin explained.

"Can't you bring Lu Wenying out of your home?"

"It's ok, but it's not easy to avoid the tracking and surveillance of '76'. Once there is a mistake in that link and their hiding place is exposed, it will be more than worth the loss." Cao Bin said.

"What's wrong with these people? Have you become so brave?"

"Oh, we can't blame them. Su Meichang turned against the '76'. Some people in our Military Control Commission have also turned against each other, and their status is not low. Several people in Shanghai were trapped. The headquarters also sent special envoys to stabilize the people's hearts. Ding Songqiao's team of men had no connection with Shanghai, so they dared to come out for activities." Cao Bin explained.

"Is the special commissioner Shanghai?"

"It is said that this time the sent were at the level of a major general and came with the mission, but it should have nothing to do with us." Cao Bin said.

"Forget it, our own affairs are messy enough, and we don't have to worry about other people's affairs. The headquarters does not intend to let us know, so we should just pretend that we don't know." Tang Jin also waved his hand and said.

"That's right, Europe has started fighting. By the way, the headquarters of the bureau ordered us to collect relevant information about the Japanese army after this organizational change. Chongqing now accumulates strategic intelligence on the next trend of the Japanese army." Cao Bin said.

"The Japanese army has increased its troops in Wuhan in the past two months. It is obvious that it is going to attack Hunan. But it is still hard to say when it will be launched, but based on the information currently available, I am afraid that it is not fully prepared." Tang Jin nodded, "If you don't talk about this, have you heard of the recording?"

"They gave me a ripped tape. Do you want to listen?" Cao Bin said, "I have ready-made equipment here."

"Call me, call Lao Lu over and listen together." Tang Jin thought for a while and gave an order.

"Team leader, is this necessary?"

"He is the deputy team leader. As long as it is our team's business, he has the right to know. Besides, three cobblers can beat Zhuge Liang." Tang Jin shouted, "Go, make a phone call and call people over."

"Yes, team leader." Cao Bin agreed, stood up, walked over and called.

Lu Xiyan did not work in the hospital. He is also a special associate professor at the School of Medicine of Zhendan University. He has few classes a week and four classes.

This is a must-go, otherwise, I would be embarrassed to get a salary from others. Of course, he doesn't care about this salary, but he cares about the job of teaching and educating people.

For those who study medicine, there are indeed many old customs and bad habits that need to be changed in traditional Chinese medicine. For example, in terms of inheritance, they like to cherish their own treasures, and they like to hide their hands, for fear of teaching their disciples and starving their master to death.

Western medicine is more open-minded. Of course, they are not apart from teaching and are also selective, but at least they should be more open in education and are not so conservative.

The progress of medicine requires the research and development of generations. If it is said to be less, it is a sense of honor as a role model. If it is said to be too big, it is also a sense of social responsibility and a sense of responsibility for the future of the country and nation.

"No, he is not at the hospital, where can he go?" Tang Jin frowned, "Did you ask, where did he go?"

"I asked, I went to Zhendan University for class."

"In class, yes, he is also a professor at Zhendan University. It is also a good idea to go to class. Call the school to see when he will be over?" Tang Jin ordered.

"Team leader, do you have to wait for Deputy Team Lu to come?" Cao Bin complained, "Can't we listen to it first?"

"Okay, let's listen first, and let's analyze it when Lao Lu comes." Tang Jin nodded.

...

"After class, I will listen to my assistant tell me that you called Zhendan University. Why? What's the matter? Call me here in such a hurry?" Lu Xiyan rushed over after class.

"Lao Lu, listen to this recording."

Tang Jin signaled Cao Bin and turned on the equipment that distributed the tape recorder.

The recording content of the "..." is omitted, roughly read according to the article of a newspaper, and it is also the newspaper of that day.

"Jansen's recording?" Lu Xiyan couldn't guess this, otherwise, why would Tang Jin ask Cao Bin to call him over?

"None of us has seen Jansen, and we have never heard him speak. The only person who knows him is Lu Wenying, but Lu Wenying is now staring at the '76'." Tang Jin said at a loss.

"Deputy Team Lu, this kind of tape requires professional equipment to make the sound come out. Not to mention it, we can't carry it directly to Lu Wenying's house. That's too big a goal." Cao Bin explained.

"Transfer via phone, how to distinguish?"

"Telectronic transmission is OK, but this will be investigated. The telephone office in the concession has long been controlled by the Japanese, and this cannot be solved simply by making a phone call. In addition, this is a recording itself. If there is distortion, there is more possibility of distortion through the phone." Cao Bin is in charge of technology in the 'Naval' group, and he understands these.

Although Lu Xiyan is not very proficient in communication technology, he also knows that telephone calls are prone to distortion, especially the longer the transmission distance, the more likely it is to distort. Sometimes interference from current signals can also lead to sound distortion.

If two people with similar tone ranges are just based on the sound of the phone, it will be difficult to determine the other person's true identity.

"Old Lu, we asked you to come here because we wanted you to help you think of a way, a message that would allow Lu Wenying to hear this recording of Jensen, but it could not directly have anything to do with us. We would help us confirm whether Jensen was alive." Tang Jin said solemnly.

"This is so difficult. Aren't you making things difficult for me?" Lu Xiyan immediately became angry when he heard this. "You two are so experienced and can't even think of a solution. How can I figure it out?"

"Lao Lu, you are a great doctor. You have studied more books than us, your knowledge is more than us, and your thinking is more active than us, so you will definitely think of it." Tang Jin said.

"You two are so proud of me. I am a medical student, not a communication technology student. How could I think of it?" Lu Xiyan was really convinced by these two people.

"Everyone thinks about it, and I'll treat you to dinner tonight." Tang Jin said.

"this……"

"Can I listen to the recording again?" Lu Xiyan asked.

"Yes, you can listen to it any number of times."

"..." Cao Bin put it again according to Lu Xiyan's request, then put it again, listening to it three times.

"This is not the first version of the recording, right?"

"Yes, it was Ding Songqiao who sent it to us after recording it." Cao Bin nodded.

"I said why I listened to the noise for a lot of noise, and the tone in some places was obviously distorted." Lu Xiyan nodded.

"Old Lu, did you think of a solution?" Tang Jin was anxious and urged.

"Let me think about it, without contact, spreading sounds, and let Lu Wenying hear it..." Lu Xiyan lowered his eyebrows and thought, and suddenly glanced at the radio in Cao Bin's house. His eyes suddenly lit up and he slapped his legs, "I have it!"

"There is a way, Lao Lu, tell me quickly." Tang Jin and Cao Bin were both shocked when they heard this.

"It's very simple. Find a radio station and let him play the recording three times at a certain time, and then let Lu Wenying pay attention to listening. I think three times are enough for her to tell whether it is Jensen's voice." Lu Xiyan said, "This way, it can prevent Ding Songqiao and the others from being tracked."

"Yes, the radio stations have such a playback device, why didn't I expect it!" Cao Bin also slapped his thighs excitedly.

"The question is, does Lu Wenying have a radio at home?" Lu Xiyan asked.

"There must be some women like Lu Wenying, who likes literary style, like to listen to music, not only have radios, but also phonographs at home, so they can rub..."

"No need to delay, hurry up." Tang Jin urged.

"Someone said to have a meal?"
