Bai Song determined a general plan, arranging a person to go to the "13th floor", find a window and put a small device there to determine the specific floor. The next thing is to continue to gather intelligence, and then figure out what the top is doing, and then destroy it in one fell swoop.

Before there is no intelligence, if you act recklessly, it will definitely not work, what if the thirteenth floor is actually a trick, in fact, there is nothing?

Moreover, the two also believed that even if the 13th floor was ready to be vacated at the beginning of the construction of the hospital to prepare for something, it was unrealistic to directly design the elevator to the 12th floor, and such a building would not pass the acceptance.

Therefore, the elevator can definitely reach the real 13th floor.

From the moment the elevator driver looked at the surveillance camera, it can be seen that there must be a special central control room here, and the location of the central control room is likely to be on the fourth to sixth floor. The main reason for this is that the leaders of those hospitals are usually on the fourth or sixth floor.

Therefore, the reason why the elevator will stop on the 12th floor when it presses 13 must be that the elevator program has been changed. The program of the elevator is very easy to change, and when many elevators are installed, they can take the initiative to provide corresponding programs according to the needs of customers.

For example, in some buildings, the elevator here only stops at the odd floor, and the elevator on the other side only stops at the even number, which is easy to set.

Bai Song thought of Wang Liang.

Last time in Nanqian Province, Wang Liang changed the small program of the base gate through the remote equipment he installed, which made Bai Song remember it very deeply. The elevator here, although there is no way to go to the elevator, but basically it is inseparable from the two weak electric wells, there is still a way.

Bai Song also told Liu Shuyuan about this situation, there is no need to send Wang Liang to this matter, there are also such talents in the Tianbei Branch, he is just talking about the ideas here.

"I don't want to go, let's be here and see if we can find anything?" Liu Shuyuan was slightly unwilling.

"If you want to find anything here, you probably have to wait for the hospital to get off work. This hospital at night, I guess there is more or less a problem, and now staying here, your car is so big, and it will increase the risk of exposure for a long time. Bai Song said: "You have to go back and report this matter to the leader and think about it in the long run." ”

"Oops..."Liu Shuyuan became entangled, "I'm afraid of delaying things..."

...

"You have a bit of ink in what you do..."Bai Song has also been close to Liu Shuyuan in the past two months, and this joke can be afforded.

"Alas... It's a big case, it's a big case after all. Liu Shuyuan wants to show himself very much, the more this kind of family is still at home, sometimes the stronger it is.

"That's no point, why don't I wait with you tonight?" Bai Song said affirmatively, "According to common sense, in my experience, this kind of thing will not happen during the day..."

Just after setting up the FG, Liu Shuyuan suddenly interrupted Bai Song and pointed to a truck that came out of the hospital: "You say, what is this car for?"

How thick Bai Song's skin was, he forgot what he had just said in a few seconds: "Outside of common sense... Well, that's normal, after all, these are smart people..."

...

Liu Shuyuan laughed, and didn't deliberately expose Bai Song, "Since you also think that there is a problem with this car, we have to keep up." ”

From this distance, he could only see a truck coming out of the entrance of the hospital, and he couldn't see anything else, so Liu Shuyuan followed directly.

"You're just like that?" Bai Song was surprised: "You're not afraid of being recognized?"

"It's fine. Liu Shuyuan was in a good mood, stepped on the accelerator to the end, and the car roared and chased after him. The car was indeed very large, with 204 horsepower and plenty of horsepower, and it didn't take long for it to overtake.

"What kind of operation is this?" Bai Song saw someone overtake first for the first time.

Liu Shuyuan didn't speak, drove the car away proudly, then turned a corner, stopped the car, and then dialed the phone.

"Brother Sun, hey, yes, it's me, hehe, don't I miss you..."After Liu Shuyuan was polite, he continued: "I'm investigating a case, and now, there's a truck I need to track, how about you do me a favor over there?"

Then, Liu Shuyuan gave the other party the license plate number, and then hung up the phone after a polite gesture.

Only then did Bai Song know that this Brother Sun, who was also invited by Liu Shuyuan to eat tonight, should be working at the traffic police command center in the city.

"Is this using Skynet?" Bai Song asked.

The installation of cameras, which began two years ago, has already achieved excellent results in pilots such as the Sanheqiao police station, and is now being rolled out throughout the city. But before that, the cameras of the traffic police department have long been all over the corner, as long as there is a highway, cameras are indispensable.

"Well, it's the equipment of the traffic police, let them control this car, and send us a location every once in a while, and where they will go in the end can basically be determined.

"Awesome. Bai Song said admiringly: "Let's wait for the good news." ”

The two chatted, and after about half an hour, Liu Shuyuan received a call, and after answering the phone, Liu Shuyuan's face was slightly dark, but he still thanked him before hanging up the phone.

"This car is going to get on the highway, it looks like it is going to go out of the city, leaving Tianhua City, the direction is Tang City and Qinhuang City, and there is no way to follow where to go. Liu Shuyuan said.

"Are you out of the city?" Bai Song was also a little surprised: "Is this really to purchase drugs and medical equipment?"

"I don't know. Liu Shuyuan shook his head, there was something involved behind this matter, and he didn't dare to find someone to monitor the hospital's car on a large scale, it would easily backfire.

"Then there is no way, you tell him to continue to add this license plate number to the system, and when he returns to Tianhua City, he will tell you when there is a relevant driving situation in the future." Bai Song said.

"Okay. Liu Shuyuan didn't call again, sent a WeChat message to his friend, and sent the license plate number again by the way.

Bai Song moved his arm: "Go back, there shouldn't be anything to collect today..."

Before he could finish speaking, Liu Shuyuan's phone rang.

"Uh-huh, which high-speed port? oh-oh-oh, okay, I see, I'll go right over. By the way, you tell the comrades over there, don't move, wait for me to deal with it. The more Liu Shuyuan spoke, the more excited he became, hung up the phone, and said to Bai Song: "There are new clues." ”

Bai Song scratched his head, his mouth opened today?

"What's so exciting?" Bai Song asked.

"When the truck entered the highway, it was a little fast, and it bumped a few times over the speed bump, and as a result, a piece of mud tile fell off the rear windshield of the car, which was captured by the surveillance video. ”

"Dropped something?" Bai Song immediately sat up straight when he heard this, this was really unexpected, "Then don't hurry up!"

"Haha, sit tight!"
