After technical processing and enlargement, the scenes around the scene can be clearly seen from the picture. At the same time, there is an electronic map of the surrounding area next to it, so that they can compare and refer to it at any time.

It can be seen that Liu was indeed very prepared and thoughtfully. Lin Hai couldn't help but look at him and felt that the policeman was indeed very mysterious, because every time he saw him, he was in a different environment, and it seemed that his position and task were very different.

Such a major case is related to the Datang Group. The police cannot ignore it and do their best, so the most elite police force must be ruled out. The Liu, who is in charge of the command, is obviously the most elite among these policemen. I wonder why such people have fallen to the grassroots police station to take care of some security issues such as fighting.

However, now is obviously not the time to consider these things. Lin Hai retracted his thoughts and focused his attention and energy on the big screen again.

This welfare home is located in a remote location and is similar to other welfare homes. After all, such a non-profit institution is obviously impossible to say that it is in a prosperous area. Therefore, naturally, the monitoring in this area cannot be said to be very comprehensive, and there is even no road section monitoring in most areas.

Fortunately, Da Liu and the others retrieved social surveillance monitors such as nearby stores and pieced them together to compare them one by one. However, from the road where Zhang Wanru and her classmate got off the bus, there were basically no shops for hundreds of meters long, so this surveillance was completely blank.

According to what the female classmate said, the direction the car was driving, Lin Hai observed the map, and then looked at Liu and the technician to confirm the monitoring location, and found that after coming out of that road, he passed two intersections, and there was basically no monitoring.

After roughly estimating the length of these sections according to the electronic map, Da Liu clicked on several of the cameras: "Because there is no surveillance at these two intersections, it is not ruled out that the kidnappers leave from these two intersections. Let's mainly look at the surveillance at the lower sections of these two intersections. The tentatively set for monitoring No. 1 and No. 2."

"There is also to continue to go down the exit, and monitor this positioning number 3."

"The three surveillance locations are about 1.5 kilometers, 1.8 kilometers, and 2.2 kilometers." Da Liu reported the numbers, "The kidnappers just caught the person and were in a hurry to leave the scene, so the speed should be relatively fast. It is estimated that the speed will not be lower than 100 kilometers per hour."

"That is, within about two minutes, the vehicles driven by the kidnappers can pass through the surveillance area of ​​these three cameras. However, other unexpected situations are not ruled out, such as the kidnappers asking for information such as phone numbers from the hostages, so we expand the time range and expand it to five minutes, no, ten minutes."

Liu issued an order: "Keep a close eye on the situation of vehicles passing by these three surveillance within ten minutes, especially the gray van."

Liu's arrangements do sound like nothing wrong, which shows that they often take these measures in criminal investigation.

Lin Hai added: "Especially pay attention to the license plate number and then verify it one by one. Criminals cannot use their own vehicles. In addition, the van is not valuable but convenient and not easy to attract attention. Therefore, it may be stolen by the criminals or obtained through other channels, and it is very likely to be a license plate car."

"Investigate some information about various license plates. Once a vehicle is stolen or a deck, it is basically the car driven by the kidnappers."

Liu nodded, and had no comment on his supplement.

Several policemen immediately began to stare at the surveillance camera and began to observe, fearing that there would be a trace of omission.

At this time, Lu Ying and Fang Zhiqiang were probably calling and contacting people. At this time, they picked up the tea made by the housekeeper and poured it onto Liu Linhai and others.

Liu was suddenly panicked. After all, Lu Ying was a legendary figure. The woman she admired in her mind. She was once the most influential person besides Ye Lingtian, and she was also a woman. So, this name is already well-known enough, even if she retired.

Now that Lu Ying actually poured tea for them himself, how could Liu and other policemen not be shocked?

Only Lin Hai thanked him with a very calm smile. Not only was he cultivated in the army that Mount Tai had not changed color before it collapsed, but the most important thing was that when he was young, Lu Ying would hug him and give him all kinds of food every time he met. Even after so many years, this kind of intimacy still did not change in his mind.

"Mr. Lu, this is so polite. We can just come by ourselves."

Zhang Youyou also took the teapot: "Mom, you just came back. Thank you so much for your hard work, I'll do it."

Lu Ying insisted very much: "Let me do it. Wanru's situation is unclear now, and I can't do anything, I can only do my best."

"This is not a small matter. I also know that the difficulty is not ordinary, and it brings a lot of trouble to all the police officers. Besides, everyone comes to my house like a guest. So of course I will be welcomed by the host."

Lu Ying has always been so calm and composed, probably she has cultivated Zhang Youyou in this way.

Lin Hai couldn't help but think of Zhang Wanru, the innocent little girl who was born and ignorant, now she is probably like her grandmother and mother when she grows up, she is elegant, mature and well-educated. Thinking of this, he is even more determined to save Zhang Wanru as soon as possible.

Lin Hai returned to the screen. Although the police were staring at him in a hurry, he did not dare to relax.

At this moment, a ringtone suddenly rang, very soft music, but at this time it sounded extremely harsh. Everyone raised their heads and stared at Zhang Youyou almost at the same time. The sound was made from the phone in her hand.

Zhang Youyou's face turned pale in an instant, and then he looked at the screen, his face even more ugly: "The unknown number must have been called by them."

The technician quickly put on his headphones and began to prepare for monitoring and recording the call. Liu also left and stood up and walked over: "Ms. Zhang, don't be nervous, everything will follow what we just discussed."

Zhang Youyou took a deep breath and nodded, and Fang Zhiqiang also clenched her hand: "Don't worry, Wanru will definitely be fine."

Lin Hai found a policeman's notepad from the table, tore off a few pages of paper, then sat opposite Zhang Youyou, signaling Zhang Youyou to look at him.

Zhang Youyou calmed down and pressed the hands-free, while at the same time, the entire living room was silent, and no one dared to make any noise.

The kidnapper's voice came through the electric current, and the voice was obviously very gloomy and cold: "Mr. Zhang, do you want your daughter's life?"

"Now don't talk about the East China Sea, the whole country probably knows that your daughter has been kidnapped. The police are probably spreading the net to find your daughter now. Are there only a group of police officers waiting for this call?"

The kidnapper's voice was full of threats, "Then I think we don't have to do this transaction anymore. Two billion was originally intended to buy your daughter's life. Now it seems that it's better to send her to heaven directly."

As soon as they said this, everyone's expressions changed. If the kidnappers were so crazy that they directly took action against Zhang Wan, then they would not have time to do anything now.

Lu Ying couldn't sit steadily and shook her body. Fortunately, Fang Zhiqiang was holding her quickly from the side, and then he quickly waved to ask the butler to come over to pour water and get medicine.

Despite this, they still dared not make any sound.

"No!" Zhang Youyou shouted out in a lost voice, her voice was completely overwhelmed with a crying voice: "Don't kill my daughter!"
