Sure enough, Zheng Yue arrived at the imperial capital early in the morning.

The first thing I came here showed how Yun Hua was injured. I felt so distressed when I saw that it was just a skin trauma.

"Dad, don't worry, it's really nothing." Yun Hua said helplessly, "I'll go to the bureau to see Gu Huaiyi today and want to record."

"I'll go with you." Tan Zheng Yue said directly.

Bo Siqing also nodded, "Then let's go together."

"You're not going to work today?"

"Not busy." Bo Siqing said.

Tan Zheng Yue snorted. He was responsible for painting for so long, and nothing happened. Now he has just returned to City S, and painting has happened so big.

"Dad, you haven't told my mom about this yet?" Yun Hua hurriedly saved the scene.

Tan Zheng Yue's face was still very dark, "I haven't said it yet, I'm afraid I'll scare her."

"Yeah, I'm fine anyway, so don't say it." Yunhua smiled and pleased her father, "Doudou is going to school. Come to Dad, let me introduce you to it. This is Lance. Yesterday he took a car with me. Well, he is a contracted artist from Xingchen Entertainment. I'll live with me for the time being."

When Zheng Yue saw Lance, he thought of his grandson, his face calmed down a little, he greeted Lance, and asked Lance how hurt he was, so that Lance should not be afraid.

Bo Siqing touched his nose, okay, everyone... he was the worst treatment, which is normal.

The group went to the Public Security Bureau responsible for investigating the case.

Gu Huaiyi was responsible for receiving them.

It is stipulated that husband and wife or immediate relatives cannot be related to superiors and subordinates, but they can be from different departments. For example, after Trang Li’s current work has been dispatched, he entered the Foreign Affairs Department and is only responsible for foreign affairs.

But Gu Huaiyi is still an old profession and criminal investigation.

The transcript is very simple, that is, I will tell you all about the incident yesterday. I will ask the car's location information, whether the car has moved, whether there are strangers getting on the car, etc.

"At present, there is only one suspicious person, the cleaner in the underground parking lot." Gu Huaiyi said, "Your car came out of Xingchen Entertainment and went to the hospital. You never stopped along the way. You only parked in the hospital parking lot at the end. During this period, only the cleaner who had approached your vehicle in the parking lot, which can be seen from the video."

Gu Huaiyi said, "We have checked the surveillance and consulted with the administrator of the underground parking lot. The administrator said that the cleaners wear such clothes and usually wear hats and masks because of dust and haze. However, there are only two cleaners in the underground parking lot. We found the two cleaners in other surveillance images at the same time. In other words, the extra third cleaners are not the real cleaners."

This is easy to understand, someone got in.

"Now it seems that this cleaner is very problematic." Gu Huaiyi said, "The car must be his move, but we failed to try to track the cleaner. We are still in the investigation stage. However... the other party has a very strong anti-reconnaissance ability. You must be mentally prepared. It is very likely that the other party will evaporate from the world and cannot be found at all."

"Sister." Lance suddenly spoke, "When we went downstairs, we happened to meet a doctor in a white coat coming out of the elevator. He was wearing a mask and glasses, and was carrying a large paper bag with some snacks on it. But I really wanted to see a glove, which was similar to the cleaning gloves in the video."

Yunhua was stunned for a moment, "When? Just when we went downstairs? I didn't notice it."

With her attention, if she has seen it, she will definitely remember it.

"Sister, you were on the phone," said Lance. "You didn't look here, and the doctor hurriedly followed the others with his head down and hurriedly left with so many people."

"Are you sure he is wearing a white coat?" Gu Huai asked.

"Yes, not only that, she is also a woman." Doudou said.

"Why?" Gu Huaiyi looked at Lance and asked with interest, "How do you know she is a woman? Have you seen her face?"

"I didn't see it," Lance said, then blinking, "but I heard her voice."

"Has she spoke?" Gu Huai raised his eyebrows.

Lance nodded, "She stepped on a person's foot and whispered a low voice."

"Wait, were you standing next to her at that time? According to you, there should be many people in the elevator. Are you sure you heard her voice?" Gu Huai asked.

Lance: "I'm sure."

Gu Huai thought for a moment and turned around and ordered another policeman to "get to adjust the surveillance in the elevator."

Yun Hua looked at Lance, "Lance, can you still remember her voice? If you were asked to recognize it, can you recognize it?"

"Yes." Lance answered without hesitation.

Gu Huaiyi was very surprised, "If you have heard her voice, you can recognize it. After all, you have only heard it once, and you still hear it in noisy environments. Moreover, the voices and tones of people speaking in different environments are different. Are you sure you can recognize it?"

Lance's smile was simple and harmless, "Yes, everyone's voice lines are different, and the frequency of voices is also different. I don't recognize the sound from the tone... I can't explain it very clearly. Specifically, it's similar to... a photo, the photos you see from your normal eyes, is a photo, but if I want, I see pixels. Analogize to the sound, what you hear is a normal voice of a person, and what I hear is a lot of subtle things. Is this possible explanation?"

Gu Huai was stunned.

Lance thought he didn't understand, so he looked at Yunhua like a request for help.

Yunhua comforted Lance's head, "It's okay, Uncle Gu understands it, he just... is a little unacceptable."

"right!"

Gu Huaiyi slapped his legs suddenly, "This, why don't we try this?"

“What to try?”

"Try whether he can tell the sound so clearly!" Gu Huai said, "We are all ready-made equipment. Try how strong his ability to distinguish sounds is."

Yunhua looked at Lance, "Lance, do you think you can try it?"

"Yes." Lance nodded and smiled at the cloud.

Everyone everywhere likes to join in the fun, and wherever there is fun, there will be people.

When it came to a little guy here, he was very sensitive to the sound test and wanted to conduct a sound recognition test, many people surrounded him curiously and prepared to see how powerful this little guy is.

You know, those who do criminal investigation have strong memory and recognition skills in sounds and images. Now, they say that there is a child who is even more powerful, so they all want to see it.

Listen once, find the only marked sample from hundreds of sound samples that press very low and sound very similar. The confusing samples selected are very confusing.

"How could it be heard..." One of the policemen who joined in the fun laughed, "To me, almost every voice is the same, and it is just two or three words short, and I forget it if I say it."

"It's really difficult. Sound memory is more difficult than image and text memory, not to mention so many obstacles set up." Another more professional said, "If it's image memory and text memory, after remembering the sample, you can think repeatedly in your mind to deepen your memory and then compare it with the given sample. However, the sound sample is forgotten too quickly, and there is no way to repeat it over and over again in your mind. If you repeat too much, the memory will be deviated!"

"The key is that all these samples press their throats so low when they make a sound, and they really sound the same!"

"I can't tell it anyway."

In order to imitate the noisy external environment, Lance did not put headphones on, but played in an ordinary non-quiet environment, which increased the difficulty.

Yunhua rubbed his eyebrows and looked at Bo Siqing beside him, "I think there are possibilities for No. 18, No. 47 and No. 69."

Bo Siqing lowered his eyes slightly, "No. 69."

"Are you sure?" Yun Hua asked.

Bo Siqing nodded, "Confirm."

Zheng Yue was quite surprised when talking on the side, "You can really hear that it's not nonsense?"

Yunhua smiled, "Dad, I can't listen to it seriously, but it should be among these three."

As soon as she finished speaking, Lance raised her hand, "No need to play it anymore, it's No. 69."

When he was speaking, the 69th had just finished broadcasting, and the 70th was about to be played.

I have to say that the test team really wanted to be a trap, and they actually put the correct sample so far behind. You must know that after listening to so many sounds, they may have forgotten what the original sample sound was!

"Are you sure?" Gu Huai asked.

Lance nodded, "It's No. 69."

For the difficulty of testing, the sample Lance listened to only two words, "Hello", but all the comparison samples afterwards were all four words, "Don't talk".

And all of them were lowered their tone and they sounded unrecognizable.

"Is it right?" someone asked.

Gu Huai raised his eyebrows, paused for a second, and nodded.

"Wow!"

Someone next to him started cheering, "So amazing!"

"This is so amazing, I just listened to it once, and it was completely different. Why did I feel that all the sounds were said by one person!"

"Awesome, this is a genius."

"It's amazing, and it's amazing."

One test cannot be done accurately, Gu Huaiyi conducted two or three sets of tests for Lance one after another, and the final result was 100% correct!

Gu Huaiyi had nothing to say now. Obviously, Lance did have a keen eye in distinguishing sounds that ordinary people could not reach.

"Let's do this, let's conduct an investigation first, and after the target is initially determined, then Lance, you can compare the voices and see who this person is." Gu Huai said.

"good."

It also takes time to investigate and determine the target initially. After the transcripts are completed, Yunhua and the others plan to go back first.

However, Gu Huaiyi called Yun Hua again, "Daihua, wait, I have something to tell you."

Yunhua was stunned for a moment, then nodded, "Okay, what's the matter?"

"This... let's go to my office to talk." Gu Huaiyi said, and then smiled at Bo Siqing and Tan Zheng Yue, "I'll borrow a few minutes to draw and talk about something private."

As he said that, Gu Huaiyi and his brothers reached out to hold Yun Hua's shoulders as if they were looking at him and took her to his office.

Bo Siqing narrowed his eyes, but he still couldn't stop him.

Yun Hua was very helpless. After being taken to the office by Gu Huai, she looked at him, "What's going on? What's going on? What's the matter? Are you talking about private matters? By the way, I haven't had time to ask you, how is Nuonuo? Is the review result good?"
