At this moment, Leng Xuan had already stepped onto the truck, and after carefully observing for a while, he didn't find any useful clues, and couldn't help frowning.

After groaning, Leng Xuan got out of the car and began to walk back and forth near the truck. Not long after, his eyes suddenly lit up, and his gaze fell on the open space two meters behind the truck. I saw that there were four vague tire marks on the ground, and from the size, shape, and clarity of the tire, it was possible to roughly judge the approximate weight of the car parked here before, as well as the model of the car.

After taking a closer look, Leng Xuan guessed that it should be a van parked here. In addition, he found traces of the van's tires grinding as it left, and through these vague marks, he could determine which direction the car was heading. After confirming this again, Leng Xuan immediately dialed Su Zhenggang's phone, told him what he had found, and asked him to help check to see if there was a van in the surveillance camera in this area.

After a while, I only heard Su Zhenggang say excitedly on the phone: "Leng Xuan, you guessed right, sure enough, a van appeared in the camera, and the time was very consistent." However, the van was a deck plate, and there was nothing to □□. ”

Leng Xuan nodded and said: "This is natural, since the other party wants to hijack people, they will definitely not use regular license plates to expose themselves." When I contacted Yu Qingqiu earlier, she said that those who followed her were very professional, and it can be seen from this that the other party should be a professional. Brother Su, since the van has been confirmed, then you should quickly use the camera to track the other party's traces. ”

"I'm investigating, they should be heading to the east of Baiyun City, you rush over there first, I have new information here to inform you immediately." After listening to Su Zhenggang's words, Leng Xuan said a good word, then hung up the phone, walked to the Ferrari car, pulled the door and sat in, and then started the car and drove towards the east of Baiyun City.

Along the way, Leng Xuan always kept in touch with Su Zhenggang, and changed direction according to the synchronous information sent by Su Zhenggang.

Originally, Su Zhenggang wanted to send a large number of police officers to trap the other party's van, and then rescue Yu Qingqiu. However, Leng Xuan was afraid that such a big movement would put Yu Qingqiu in danger, so he rejected Su Zhenggang's proposal.

According to the direction provided by Su Zhenggang, Leng Xuan gradually drove out of Baiyun City and headed towards the suburbs. It didn't take long for him to find himself in a relatively remote place. There are not many households within 10 kilometers of here, but there are a few factories, but they are all abandoned. Because there were no surveillance cameras installed outside the outskirts of Baiyun City, Leng Xuan could no longer get much help from Su Zhenggang.

After parking the car in a hidden area not far from the abandoned factories, Leng Xuan got out of the car and began to approach the abandoned factories. According to his speculation, this area is deserted, and those who have kidnapped Yu Qingqiu should have nowhere to hide, and the only hiding places in this vicinity are these abandoned factories.

Looking at the appearance of this abandoned factory, it used to be a chemical factory, a polluting production and processing area, and because of this, this kind of factory will be built in such a remote place, but over the years, the state has been cracking down on polluting enterprises, and it is normal for chemical factories like this to close down.
