"Which hotel are you in now?"

"This side of Tsim Sha Tsui, the Regency Hotel. ”

"Don't move, just keep an eye on his car, I'll be there right away." After speaking, Zhuo Yirou hung up the phone.

"How's that, how's that?" said Grandma excitedly, jumping to her feet, "What did Rourou say over there?"

Yan Caiyingdai frowned slightly and said, "Rourou asked me to keep an eye on the suspect's car and stay still." ”

"Ah, why is this so?" Auntie, who had never been a police officer, took it for granted, "Why don't we go to the front desk to check the whereabouts of the suspect first, anyway, you have a police card and can bluff people." ”

Yan Caiying's face was obviously hesitant, but after thinking about it, she still shook her head and said, "Let's do as Rourou says, she has more experience than us in this regard." ”

"Oh, well!"

I have to say that it was Yan Caiying's decision that gave Zhuo Yirou the opportunity to follow Yang Tang, otherwise once she went to the front desk to check Yang Tang's room, she would definitely be noticed by the red queen of the surveillance network.

Just when Yang Tang and Lei Tiandong occupied a corner in the business suite to rest, Zhuo Yirou put down the work at hand and drove to the Lijing Hotel.

"Where's his car?"

Hiding behind the stairwell door of the garage, Zhuo Yirou asked Yan Caiying beside her.

"Over there, there's a third ...... in the corner."

Zhuo Yirou held a small military telescope and looked into the distance according to Yan Caiying's instructions: "I see, I see, that open-top Lingzhi is it, right? DK1001, yes, it's this car!"

"So what are we going to do now?" asked the concubine with a bad idea, "Why don't we put a tracker on that car?"

Zhuo Yirou glanced at her with contempt, and said: "You've watched too many movies, don't you say that I came here privately today, even if I'm on a mission, I have to apply to the top to use the tracker, personal privacy, understand?"

"What the hell is going to do? You can't just look at it, right?" Grandma seemed to be more anxious than the two best friends who were police officers.

"Or ...... Or go to the front desk and ask?" Yan Caiying suggested.

"No, I can't. Zhuo Yirou waved his hand.

"Why not?" said the concubine, puzzled.

"In your report, you said that there was a bald head who went up with Yang Tang, right?" Zhuo Yiju said, "Actually, I have taken pictures of Yang Tang and that bald head, and they are obviously in the same group, but it cannot be ruled out that they have other accomplices, and what if their accomplices are in this hotel? What if the accomplices are mixed in with the hotel service staff? We check at the front desk, won't we startle the snake?"

Hearing this analysis, Yan Caiying and Concubines looked at each other, although they felt that this possibility was very small, but it could not be completely ruled out, so they could not take risks.

"That'...... Gotta find a way, right?"

Zhuo Yirou thought for a while and said, "In this way, I will contact my old colleagues in the Ministry of Transportation to see if they can help." With that, he went up half a flight of stairs and made a phone call around the corner.

"How can the traffic cops help?" said the princess didn't quite understand.

"Don't you mutter, okay? ”

After a while, Zhuo Yirou came back with a hint of inexplicable joy on her pretty face: "Which of the two of you brought a laptop?"

"I—" Grandma raised her hand like a schoolboy.

"Where's the computer?"

"In the Yingying car. ”

"Then go get it and lend it to me. ”

"No problem!"

Inside the Beetle.

Zhuo Yirou tinkered with Grandma's laptop in the passenger seat for a while, then connected to the IFI and opened a special page, on which several equal dynamic small pictures quickly popped out.

"It's ......"

"The video surveillance of the Ministry of Transportation at various intersections, I asked my colleagues to help me pick it up. "Look here, you can enter the license plate in these boxes, and then the monitoring at each intersection will help automatically find and lock the ......."

"So powerful?!" Concubine was shocked, and even Yan Caiying was a little surprised, because it was the first time she had come into contact with this thing.

"It's not great...... Because of the use of motion capture technology, which is not yet mature, it is easy to lose the target if the traffic is too large or the speed is fast enough to pass through the intersection. Zhuo Yirou explained, "More importantly, this method is only monitored at each intersection, and there is no such thing as the monitoring of general road sections, otherwise the cost of the entire road supervision system will be lost." ”

Zhuo Yirou explained to the two girlfriends while entering the license plate number in a few blank boxes.

"Hey~~ Why did you lose two license plate numbers at once?"

"That's another bad thing about this system. Zhuo Yirou said a little helplessly, "It tracks and locks one license plate and locks two license plates in the same proportion of hardware resources, but if you want to chase three license plates at the same time, the resources required will have to be doubled." ”

"You can chase two cars at a time, that's good, what's wrong?" Grandma obviously hasn't actually handled a case, so she thinks this kind of setting of the motion capture system is not bad.

Zhuo Yirou glanced at her when she heard this, and said: "It seems that your thinking is still parked in the early years, at that time, the suspects who came out to commit crimes were relatively poor, and they could get a second-hand car, or steal a car, and use it to commit crimes, the suspects were more satisfied, and now there are more and more cars on the highway, and car theft cases are frequent, so capable gangs will get a few more cars, and commit crimes in a planned and premeditated manner, so the dynamic capture system, which doubles the resources occupied by every two license plates, is overstretched." ”

"I see......" the concubine suddenly said.

Yan Caiying said: "Then why didn't the software designers take the current factors into account?"

Zhuo Yirou smiled bitterly: "Heh, software designers are only proficient in software, and the current annual growth rate of social consumption has not even been foreseen by those economists, let alone software experts." ”

In fact, this lack of foresight has even been made by the US Department of Defense.

For example, the Seawolf submarine of that year, in order to fight against Soviet Russia, the cost of a Seawolf was as high as two or three billion, completely high-tech stacking, and then a few years after the collapse of Soviet Russia, the US Department of Defense canceled the follow-up Seawolf order, and instead built a simplified version of the Seawolf, that is, the Virginia-class attack nuclear submarine, the cost of a single one is at least one billion cheaper.

Another example is the F22 Raptor fighter, it belongs to the fifth generation fighter, the design concept is very advanced, but the cost is quite expensive, it was finalized as early as the end of 2001, and it can be mass-produced, but due to the delay of the fifth-generation fighter research program between China and Russia, the F22 lacks accurate air combat objects or competitors, and the cost is too expensive, so some orders had to be cancelled, and later filled by F35.

The above is still a semi-failed example, and even the US Department of Defense has studied a certain wartime system for several years, but as a result, due to the rapid development of smartphones and wireless networks, the concept of wartime systems has lagged behind the contemporary situation. It is equivalent to spending money in vain and it is a lot of money, and it has been tossed for a few years, but the system has no use after it comes out, which is simply laughable.

"But the only advantage of this system is that with its dynamic capture, as long as Yang Tang comes out and doesn't drive too fast, we can hang far away without getting too close. Zhuo Yirou was still a little proud when she said this, "I have secretly fought with Yang Tang, and he is not a fuel-efficient lamp, so it is not easy to track him." ”

When the concubine heard this, she suddenly became interested: "Rourou, how did you fight him?"

Zhuo Yirou glanced at Yan Caiying and said, "Why are you asking so much? Gossip girl!"

"People are curious!"

"Less ......"

After waiting for about a quarter of an hour, the concubine, who had just shut up, said impatiently: "Are we just waiting for the rabbit?

"Nonsense, going up I went in the morning. "Zhuo Yirou doesn't have a good airway.

"But I'm so sleepy......"

"Then you go to sleep in my car, Yingying's Beetle's space is a little small. Zhuo Yirou suggested.

"Okay!" Ah Fei took Zhuo Yirou's car keys, pushed the door and got out of the car.

Waiting to see the concubine get into his car, Zhuo Yiju said: "Yingying, now there are only the two of us left, divide the work!"

"The old rule is to change every two hours, but I'm a little sleepy now and want to rest first. Yan Caiying said.

"Okay, now it's 3:20, I'll call you at 5:20!"

So the two women went their separate ways, one continued to monitor, and the other slept on the steering wheel.

Time passed quickly, and Zhuo Yirou, who had not seen Yang Tang's figure for two hours, woke up Yan Caiying and said, "It's already five o'clock twenty-five, it's for you!"

"Okay..."Yan Caiying took the telescope handed by Zhuo Yirou with sleepy eyes, "Really, I'm on vacation today, and I don't know what kind of crazy thing I sent to you, I actually want to accompany you to squat." ”

"You can still take a vacation, I haven't closed my eyes since yesterday afternoon tea. Zhuo Yirou leaned her body on the backrest, completely relaxed, and quickly fell asleep.

"Who told you to fight so hard...... Yan Caiying wanted to say more, but found that no one answered, turned her head and saw that Zhuo Yirou was already asleep, "Sleep, sleep, I'll keep an eye on it for you, I won't let that guy slip away." Suddenly, she remembered her dead ghost boyfriend.

Unconsciously, half an hour passed, Yan Caiying, who didn't wake up, felt that her spirit was very empty, tiredness hit, and she almost squinted, just at this time, she only heard a jingling sound in the quiet basement, and then the elevator door at the far end slid open to both sides, and two people came out of it, not Yang Tang and bald Lei Who else.

Yan Caiying was stunned at first, then grabbed the binoculars and wanted to take a closer look, but she put it down abruptly, and said to herself: "Look at the shape of the body, it should be the two of them, the other party is difficult to entangle, so don't use the telescope to startle the snake." So she pushed Zhuo Yirou beside her, "Hey, wake up, wake up, wake up......"

"What's wrong?" Zhuo Yirou woke up suddenly, with a hint of vigilance in her sleepy eyes.

Yan Caiying pointed to the parking space: "Do you see if one of the two is the target?"

Zhuo Yirou looked at it, and sure enough, she saw Yang Tang Lei Tiandong, but she still wanted to confirm, after all, it was fifty or sixty meters away, and the person's facial features couldn't be seen clearly, so she stretched out her hand and wanted a telescope.

Yan Caiying didn't give it, and explained: "Don't you say that he is a master." If he looked through the telescope, he would definitely notice something. ”

Zhuo Yirou was stunned and said, "That's right, that's right...... Look, DK1001 really moved. ”

"Shall we follow up, then?"

"Don't be busy, I'll adjust the motion capture first, you call Grandma's mobile phone, wake her up, let her drive my car to follow, it's no problem to get closer, once Yang Tang finds out, let her overtake!" Zhuo Yirou commanded.

"But she doesn't even know what Yang Tang looks like, how can she follow her?"

Zhuo Yirou was a little speechless when she heard this, and said: "What you want is that she doesn't know Yang Tang, otherwise her concubine's acting skills won't be exposed, just let her keep an eye on the license plate!"

"That's right, that's right, I'm going to call her on her phone. ”

So the concubine who received the instructions drove Zhuo Yirou's office car and left the basement first, and then under Zhuo Yirou's command, she quickly followed DK1001!

Coming out of the Lijing Hotel, Yang Tang drove all the way to the east, unhurriedly in the direction of Saigon. However, after three forks in the road, he received a prompt from the red queen: [Master, there is a Honda sedan behind us all the way.] ]

[Oh, what's the way the car came from, have you checked?]

[It has been checked, it is the car of the Regional Crime Unit of Hong Kong Island under the jurisdiction of the Hong Kong Police Force.] ]

[Heh, it's a police car...... How will it keep up with me?]

[I don't know, but the only person in the car wasn't a police officer, but a fitness girl.] ]

[Not a police officer driving a police car?] Yang Tang was surprised.

[I just checked her online traces again, and found that she has frequent contact with Zhuo Yirouyan Caiying, and it should be the best friend of the two of them. ]

"Oh, it's a little interesting......" Yang Tang subconsciously said the last sentence.

Hearing this, Lei Tian asked, "What's interesting?"

"Don't look back, there's a tail following behind, I recognize the license plate of that Honda, it should be the car of the Serious Crime Team!"

"Serious Crime Team?" Lei Tiandong said strangely, "I remember you told me that the policewoman who checked the car in the morning was also from the Serious Crime Team, right?"

"It should be...... I've only heard others mention it, so I'm not sure. Yang Tang said.

"I'm not sure, we can't take a tail to the meeting place, can we?"

Yang Tang said noncommittally: "Then you say, do you want to get rid of it, or play with it first." ”

"Whatever you want, just keep an eye on the time. ”

"That ......"

Seeing that Yang Tang was about to make a decision, the red queen reported: [Master, I just found that the surveillance video at each fork in the road will automatically lock two license plate numbers, one of which is DK1001!]

[DK1001? Isn't that the license plate number of my car? But it's normal to think about it, there is a police car behind me, and the road supervision system doesn't do anything, isn't it abnormal?]

"Hey, boss, what do you mean by not talking?" Lei Tiandong couldn't help but ask, "Do you want to play with the car behind you, or get rid of it?"

Yang Tang said: "I don't think I need to play or get rid of it, just let it follow!"

"Then let's go ......"

"It's okay, it's easy to get rid of the tail, just look at it. ”

Lei Tiandong shrugged his shoulders and pursed his lips, expressing his confusion and not asking much.
