These words...

Could it be that Zhou Jiancheng’s life is in danger?!

"What's wrong with this recording?"

Hearing Qin Ting's question, He Liuyang knew that Qin Ting was planning to save Zhou Jiancheng.

He didn't answer, but took out his mobile phone and dialed Xiaoliu's number, "Is it convenient to come out?"

When Xiao Liu heard He Liuyang's voice, he woke up immediately. It was as if he was transported back to the time when he was on a mission in Africa. He sat up from the bed and said, "It's convenient."

"I need to analyze a mobile phone recording. The other party may be being held hostage and his life may be in danger at any time."

"Understood! I'll take people there immediately."

He Liuyang hung up the phone, and Qin Ting was looking at him with wide eyes, not hiding her shock.

He Liuyang held her hand, took the phone from her hand, and played the recording again. Zhou Jiancheng's voice came from the recording, and his laughter showed a slight tremor.

If He Liuyang hadn't already heard the problem, ordinary people wouldn't notice the problem even if they listened to it ten more times.

"Is his life... going to be in danger?" Although she hates Zhou Jiancheng, she never wants him to be killed. He is currently the only person who can help the police find the murderer. If he dies, the murderer case will be over.

It will really cut off all the clues!

"Not when I was talking to you, not now, not necessarily."

Qin Ting's heart suddenly sank.

If Zhou Jiancheng had fallen into the hands of the murderer, according to the murderer's killing habits, Zhou Jiancheng would have been dismembered by now!

Half an hour later, Xiaoliu came over. Two other people came with him. Qin Ting had never met these two people, but they all said hello to He Liuyang, so it was obvious that they were also people He Liuyang knew.

"This is a cell phone recording." He Liuyang put the cell phone on the table and played the recording.

When Xiao Liu and the other two heard this, they both frowned at the same time.

They were from the intelligence department, and audio recognition was just the basics, plus their usual interrogation experience. As soon as they listened to this audio, they immediately heard something was wrong. Xiao Liu poured out the audio and put it into the computer he brought.

The voices of Zhou Jiancheng and Qin Ting were separated, and in the end only the background sound of the two talking was left.

One of them took the background sound and decomposed it again according to the sound wave frequency; the last person picked up the headphones and directly identified the analyzed various background sounds.

"There was no sound of vehicles, so it must be in the suburbs."

After the person in charge of listening finished speaking, Xiaoliu's computer immediately pulled up a map of the capital and located it in the suburbs.

"There is the sound of water leaking from the sewer. It cannot be ruled out that it is an abandoned construction site."

"There are abandoned construction sites in Beijing located in two suburbs..."

The three people cooperated in an orderly manner, and the investigation and positioning were very precise and very fast.

When Qin Ting was in the Criminal Investigation Brigade, this kind of investigation was all handled by the physical team of the Criminal Investigation Brigade, but it often took several days to make any progress. Looking at the cooperation efficiency of the three of them, for the first time, she felt that there was someone else outside.

Eye-opening.

"Boss, there are three waste construction sites that meet the requirements." Xiao Liu said, having already taken the computer over, opened it and showed it to He Liuyang.

He Liuyang looked at three places, pointed to one in Yanjiao and said: "Exclude this place. Judging from his past crime preferences, the conditions here are too remote and lack of challenges. It is now four ten in the morning. Qin Ting, will this place be eliminated?"

The two addresses were sent to the people in the Criminal Investigation Brigade."

Three years of special operations career gave He Liuyang an unusually precise control over time.
