Lin Hai took the headphones from the technician and listened carefully to the recording. When the kidnapper called just now, he was concentrating on helping Zhang Youyou deal with the kidnapper's conversation, so now he has to listen again because he vaguely felt that some very important information was left out on the phone.

Everyone held their breath and did not dare to let out the air, for fear of making a sound to disturb Lin Hai.

"It's here!" Lin Hai decisively pressed the pause button, then turned the recording forward a little, and handed the headphones to Liu: "Listen."

Liu listened attentively and heard the arrogant voice of the kidnappers threatening Zhang Youyou: "I'm not afraid of you calling the police..."

Liu frowned and listened carefully. Lin Hai reminded next to him: "Don't you let you listen to what he says? If you listen to other sounds, is it like there is the sound of an agricultural motor vehicle in the distance?"

Liu suddenly had a sharp eyelid, and then he turned back the paragraph and stopped it carefully. If Lin Hai had not reminded him, he would have focused all his attention in the words of the kidnappers, and it would have been impossible for him to notice such a subtle thing.

After listening to it twice or three times, Liu basically confirmed that Lin Hai was right, it was indeed like the sound of an agricultural tricycle coming from a distance, which was very vague, and only Lin Hai could notice this at the first time.

Donghai City has been banning such agricultural vehicles from entering the city many years ago. Combined with Lin Hai's analysis and judgment just now, everyone instantly got an answer.

"So, the biggest possibility is that the kidnappers are hiding in a village that has been going west." Liu slapped the table hard and wiped his face, feeling that he seemed to see a glimmer of light.

However, after going westward, they were all villages and towns. Although the population is now small, the area is still large. Dozens of villages and towns are not a joke, and the police force is limited, so it is impossible to search in a net. Moreover, people in the countryside are familiar with each other. Once outsiders are found, they will easily be discovered immediately. At that time, they will be discovered by kidnappers before they are found.

"If it really doesn't work, we might as well send someone to secretly block the intersection of the outer ring road in the west." The policeman named Li Jin suggested, "Now that the kidnappers are hiding in this area, he will definitely come back tomorrow afternoon to conduct transactions. Then we will set up controls in advance and find suspicious vehicles."

Without thinking, Liu shook his head and refused, and said coldly: "This is unrealistic."

"We only know that there are at least three people in the group that have kidnapping, but what if the other party has accomplices staying in the city to respond? Even if there is only one person, the transaction is enough, and then claim that they will wait until the transaction is over and then release them, are there still few such kidnapping cases?"

"Also, there are so many roads between villages and towns, they can take other roads. Do you say that you can control every road?"

"What's more, so far, we don't know what kind of vehicles the kidnappers are using, let alone so many vehicles entering and leaving the North Outer Ring Road every day. You said you should check the controls, how do you check it? You stop the cars and check it? Not to mention that there are also safety hazards that cause traffic problems. Do you think the kidnappers will not be able to find it?"

When Liu said that, he still frowned. The problems now are one after another. He was looking at finding a big direction, but this direction was too big, so people couldn't find it.

Time passes quickly, and now it is already past midnight, which means that there is not much time left before the kidnappers agreed.

"Then maybe, let's notify the cadres of each village and town to find out if there are any suspicious vehicles entering. If so, we will inform you and we will further rule out and search..." Another policeman said, but before he finished speaking, he shook his head and denied this method.

After all, these grassroots cadres can't say that they are guarding the entrance of the village and observing every vehicle entering and leaving. If they want to inquire about the news, they have to visit them from house to house. Isn't this time period of the night equivalent to informing the kidnappers?

Liu was a little anxious. Their current situation can be said to be equivalent to falling into the darkness before dawn. It seems that they have found very important clues, but everyone is at a loss for how to break through this deadlock.

Lin Hai also felt that now he was trapped in a fog. But he was definitely not the one who could give up so easily. Moreover, if he gave up, then what he gave up was Zhang Wanrusheng's hope.

He subconsciously lit a cigarette and thought quietly. It was not that he was rude and ignored the fact that there were women around him. It was mainly that he was used to think, and to a large extent, it was because he was influenced by Ye Lingtian since childhood and always smoked a lot of cigarettes when he was working and thinking.

At this time, Lu Ying was nervously worried, but she looked at Lin Hai from time to time and looked at him with a thoughtful look.

Lin Hai turned around and suddenly raised his head and asked Da Liu: "Officer Liu, I'll ask you, you have been exposed to a lot of kidnapping cases over the years, right? I want to ask you, what kind of kidnappers would ask for so much cash at the first time they opened their mouths?"

Liu subconsciously replied: "Donghai City has a developed economy and is also a place where wealthy people are concentrated, but the public security management is strict. There are not many kidnapping cases, and there are not many more people who say less."

"But I have never said that there is such a high ransom of 2 billion yuan in cash, even in the country, it is unique."

"Of course, it may be that the kidnapper thinks that Miss Zhang Wanru is the identity. After all, she is the daughter of Datang Group. Everyone knows how huge the assets of Datang Group are. The kidnappers should also think that 2 billion yuan is nothing to Datang Group and Mr. Fang and his wife. If it were another company, I think it would not be so high, because I know it is impossible to get it."

Lin Hai shook his head: "If it were to kidnap other people, it would be impossible to ask for so much money, but it is not the first thing to do to kidnap the daughter of the Datang Group."

"It is impossible for them not to have thought of the consequences of doing this. First of all, the strength of the Datang Group is here. If Mr. Fang and Mr. Zhang can't swallow this after saving Miss Wanru and others, and if they want to catch them at the ends of the world, they will probably not be able to afford this consequence."

"And if..." Lin Hai said, looking at Zhang Youyou with some concern, "What I said is that if they don't plan to put Miss Wanru back, then obviously Mr. Fang and Mr. Zhang would do anything and would not let them go."

"So these 2 billion sound tempting, but in fact it's not that easy. Maybe you'll lose your life. Judging from the arrangement and arrangement of the kidnappers, the kidnappers are not brave but have superb anti-reconnaissance methods, including the arrangement of the entire plan, and it is very likely that they are 100% sure to escape."

"Who can such a person be?" Lin Hai looked at Da Liu, then looked at Fang Zhiqiang and Zhang Youyou, "Who can be confident of escaping from the police and Datang Group, escape from legal sanctions and revenge of Datang Group, what kind of desperation is this?"

"And you have heard the call just now. The kidnapper who called was obviously the mastermind of them and the leader of this kidnapping case."

"And the kidnapper said clearly that he was not afraid of the police or called the police. Although this attitude was too arrogant, could it be that the kidnapper had such confidence and felt that the police could do nothing to him?"

Liu frowned: "Do you mean, is the kidnapper a prisoner who has had a criminal record?"

This has been mentioned before, but obviously this clue is also a needle in a haystack, so it is impossible to find out.
