Chapter 195 Darts
Cui Jian knocked on the screen, opened it, and saw Ye Rannuo. He found that she was using the public surveillance camera to perform facial recognition on people approaching the villa complex to prevent suspicious people from approaching the villa complex. It looked very technological. When a face appeared on the surveillance camera, a green frame would immediately pop up, read out the facial information, and automatically compare it with the database.

Seeing Cui Jian's curious look, Ye Rannuo replied, "This is the system used in London subway stations. It can read 3000 faces at the same time."

Cui Jian: “Is it that powerful?”

Ye Rannuo: "Is this amazing?"

Cui Jiandao: "I said computers are amazing, they have such strong computing power."

Ye Rannuo was startled. Cui Jian was not a complete novice. Cui Jian looked at Ye Rannuo and seemed to know what she was thinking. He said, "Basic knowledge. Does that mean there is an independent server in the villa?"

Ye Rannuo did not deny it, and said: "What you said is not called a server, but a mainframe, also called a large host or host server, and the more professional name is a high-performance computer. The earliest mainframe name came from the CPU, because it was very large. The CPUs of our home computers are all microprocessors."

Ye Rannuo: "The independent server you mentioned usually refers to a large storage device with basically no computing power, which is mainly used to store data. For example, the traffic monitoring system will send data to the server, and the data can be retrieved from the server when necessary."

Cui Jian handed over a piece of chocolate, and Ye Rannuo took it: "Thank you." The chocolate tasted sweet, and Cui Jian didn't seem so annoying anymore. It seemed that she had never thought that Cui Jian was annoying, except that he unilaterally terminated the lease, which made her angry. Cui Jian terminated the lease without asking for permission, without any prelude or discussion with her, and directly notified her of his decision.

This was the first time Ye Rannuo showed her knowledge to Cui Jian, and it was also what she had always wanted to do. When she ate the chocolate, she was about to say something, but Cui Jian had already left the screen compartment and went to Duanmu. Ye Rannuo felt a little disappointed, but the chocolate was still delicious anyway.

Duanmu was zooming in and out of a screen. When he saw Cui Jian coming over, he said, "Susan divided the duty personnel into two groups, one for positioning and the other for patrolling. Assuming everyone works diligently, it will be difficult for thieves to sneak into the villa complex."

Cui Jian: “But?”

Duanmu smiled: "No buts, haha, let's go out for a walk."

The two left Villa No. 1, got on a balance bike placed in a shed on the side, and went to Villa No. 2 via the asphalt road. The work badges of ordinary bodyguards are blue, Duanmu and Cui Jian's are green, and Susan's is red. The positions can be distinguished by the naked eye from the color.

Duanmu walked along the asphalt road of the equilateral triangle and carefully observed the street lights and green shrubs. During this time, he learned about the work of ordinary villa staff from a maid. Cui Jian was half-hearted, riding a balance bike and following Duanmu, looking around.

Susan's voice suddenly came from the intercom: "Patrol personnel, go to A5 immediately." A corresponds to Building 1, and 5 corresponds to designated post No. 5.

Duanmu took out his tablet and looked at the map. A5 was located 1 meters away from Building 20, near the wall, on the grass beside the asphalt road. There was a tree here, and the A5 work area was centered on this tree.

Duanmu and Cui Jian were not the first to arrive. When they arrived, there were already three patrol members on the scene. A bodyguard in a suit was lying on the ground. The patrol members undressed him, took off his bulletproof vest, and checked his heartbeat.

A patrol officer wearing gloves picked up a flying needle syringe on the grass and reported: "Calling 01."

Susan: "01 received."

The patrol officer said, "This is a powerful tranquilizer dart used by the police for wild animals. A5's bleeding is not serious, but the dose of the dart is very large, which may endanger his life. Emergency medical assistance is required."

Susan: “I understand.”

Duanmu looked at the tranquilizer dart for a while and asked, "Is this for killing bears?" The tranquilizer dart fired by a gun will automatically inject after hitting the target. The larger the beast, the longer the needle and the greater the dose. If the bodyguard did not pull out the dart as soon as possible after being hit by the dart, the human body would not be able to withstand such a large amount of anesthesia.

Cui Jian looked up and around. About ten meters away was a 3.5-meter-high wall with an electric fence. Twenty meters away was Villa Building No. 20. Apart from that, there were no other high points nearby. Where did the tranquilizer dart come from?
Before Cui Jian could think clearly, Susan said, "C2 is down, please check the patrol post immediately."

C2距离3号别墅35米，距离围墙20米，周边开阔。距离C2最近的定岗保镖在20米处。这位定岗保镖是看着C2瘫软在地。

C2 was in the same situation as A5, both were attacked by tranquilizer darts. However, A5 was stabbed in the left thigh, while C2 was stabbed at the junction of the neck and shoulder. He felt the tranquilizer dart at the first moment and pulled it out immediately, but even so, he was knocked to the ground. A5 was stabbed in the back of his left thigh, and A5 pulled out the dart a little later.

Duanmu picked up the syringe and looked at it, then said, "There are two possibilities. The first possibility is that someone outside the fence used an object similar to a fishing rod to tie the camera and darts together, stretched the rod over the fence, aimed, and then fired. The second possibility is that the drone was remotely controlled to launch it."

Cui Jian laughed and watched Duanmu talking to himself.

Duanmu continued: "In principle, the second possibility is more likely, but the dart does not fit the second possibility."

Duanmu waited for a while, then looked back and saw Cui Jian still laughing, and said, "Please give me some compliments."

Cui Jian asked: "Why?"

Duanmu said: "If they use drones to launch darts, they will choose darts with smaller size and smaller needles. The pain will be less when it enters the flesh and it is easy to be ignored. It should be the first possibility. The road outside the villa is a public road. The villa group has no right to install surveillance and has not arranged bodyguards."

Cui Jian: "The third possibility is that the person who shot A5 came from Villa 1. The person who shot C2 came from Villa 3."

Duanmu: "What's the purpose?"

Cui Jian: "They were just sitting around shooting for fun. Or maybe they couldn't pay the salaries, so they killed as many as they could. Or maybe they confirmed that these two were traitors, so they killed them with tranquilizer guns."

Duanmu was stunned. "Yes, it is possible. It is difficult to come up with evidence to prove that A5 and C2 are traitors. If we dismiss them hastily, we may be sued in court for compensation. It is best to use tranquilizer guns to knock them down so that they cannot participate in the security work of the villa."

Cui Jianzan: "You are so smart." I don't believe it myself, but you actually believe it.

Duanmu: "Hey, show some spirit and come forward to give my special forces captain some face."

Cui Jian: "Even if I work harder, can I be as smart as you?"

Duanmu: "That's impossible. Although you have a good brain, there is still an objective gap between you and me..."

Cui Jian: "So I chose to slack off."

Duanmu: "Three cobblers are better than one Zhuge Liang. Your idea just now is very good."

Cui Jian: “I came up with some good ideas when I was just slacking off.”

Duanmu: "Make up another one."

Cui Jiandao: "Susan knocked down A5 and C2, which greatly increased the bodyguards' vigilance. At the same time, she created the illusion of an attack, so that those who wanted to attack would not dare to do so."

A and B both wanted to talk to Xue Bing. When they were preparing to attack, they suddenly found that someone had attacked the villa complex first. This was a variable in their plan, so they had to consider the possibility of C when making plans.

Duanmu felt that what Cui Jian said made sense, but then he felt that it was meaningless, because Cui Jian only said it was possible, and lacked a verification method. Assuming that Susan really knocked down A5 and C2, Susan would not admit it. It can be said that Cui Jian said nonsense that made sense. Until lunch time, no further incidents occurred. The two bodyguards C2 who were sent to the hospital were not in danger, but just fell into a coma. A5 was rescued and was no longer in danger, but there was no sign of waking up.

In order to avoid the criminals' plan to reduce the number of bodyguards, Susan hired 20 more Hancheng bodyguards, who will start work tomorrow morning. Duanmu told Cui Jian that maybe the criminals' purpose was to make Susan hire more bodyguards.

Duanmu and Cui Jian were walking on the sidewalk. Duanmu said, "Don't you find it strange? If it was just to protect Xue Bing, there would be no need to arrange such a scene. At present, it is estimated that Xue Bing is only at risk of being kidnapped and not worth being killed. Xue Bing might as well let the bodyguards guard a villa."

Cui Jian praised: "What do you think?"

Duanmu said: "I think someone wants to kill Xue Bing."

Cui Jian: “Why?”

Duanmu: "Murder him."

Cui Jian: “Are you sure?”

Duanmu: "Not sure, because I don't know Xue Bing's exact identity."

Cui Jian asked: "What was the black box you asked me to take from Ye Rannuo last time?"

Duanmu said: "The encrypted information of the execution team."

Cui Jian sighed, "I shouldn't have asked because you would lie anyway."

Duanmu smiled and changed the subject: "I'm quite curious. According to my information, Ye Rannuo has resigned from Dayin Group and lives in a villa complex. Why does he still have to keep a residence outside?"

Cui Jian said: "Changing the living environment can improve physical and mental comfort. Do you know who attacked me, Ye Rannuo and Shi Feng?"

Duanmu nodded: "I can guess, let me think about how to explain it to you... In your opinion, Ai Li and Shi Feng are the most steadfast allies in this matter, right?"

Cui Jian: “Yes.”

Duanmu: "From their perspective of survival, it is true. But from the perspective of information scarcity, it may not be true. Shi Feng knows that it was Feidi who met Xue Bing, and Ai Li knows that it was Feidi who met Xue Bing. If Shi Feng dies, won't Ai Li be able to monopolize this resource?"

Cui Jian: "Ai Li? I never thought she was a good person, but I don't think she would kill Shi Feng. After all, she had many opportunities to do it."

Duanmu: "Do you know that Ellie is an agent?"

Cui Jian: "Should it be called Jiandie?"

Duanmu: "It doesn't matter, it means the same thing. What? You still can't think of it?"

Cui Jian suddenly realized: "Bing Ci." Bing Ci pretended to be Ellie's boss and killed Shi Feng. Ellie was forced to turn against her boss and had to rely on Bing Ci, or Edward's boss.

Duanmu Wuyu: "Ellie's boss. Before this, Ellie and Shi Feng were both on the run together. The boss ordered them to be eliminated, which might have resulted in their deaths. It was not until Shi Feng escaped from prison that the two officially separated. At this time, Ellie's boss detained Ellie in the police station in order to protect her and preserve her value. At the same time, in order to increase Ellie's value, he ordered Shi Feng to be killed."

Duanmu sighed, "Who knew that Shi Feng, under your deception, would post all the information online. This fire can only burn Xue Bing. This is why we are here."

The two walked into the living room of Building 1. There were twenty Buffet stoves placed around the room, which were used to keep food warm. The bodyguards were eating at the shift change. Everyone was talking in low voices and had serious expressions. They were probably worried about A5. Although they were not familiar with A5, they were saddened by the death of the rabbit. No one knew if they would be the next person to be attacked.

Cui Jiangang had just picked up the plate when he heard someone outside shout, "Drone."

Everyone walked out of the living room and looked up at the sky. A drone was hovering hundreds of meters in the sky. In fact, the small drone could not be seen by the naked eye. It happened that the sun was shining directly, and the drone blocked part of the sunlight. It was then discovered by the bodyguard who was about to enter the living room for dinner.

Drones bring a sense of powerlessness to everyone. They know that bad guys are watching them, but they have no good countermeasures. At present, the only countermeasure is that Ye Rannuo chases the remote controller through wireless signals.

Most of the portable anti-drone weapons on the market currently have limited range, and even military radars sometimes find it difficult to detect the presence of drones.

At present, the range of mature anti-drone guns can reach 2.4 meters, emitting 5.8GHz to GHz electromagnetic interference waves, thus achieving the purpose of forced landing of drones. Difficulty : Many high-end drones have built-in systems, and once interfered, they will return to the original route. Difficulty : To shoot down a drone, you must first find the drone. Not to mention at night, it is also difficult to find a drone hundreds of meters away during the day. Difficulty : Each anti-drone gun costs up to US dollars.

Another way to defend against drones is to establish a military anti-drone system, which includes radar-like and electromagnetic transmitters. However, installing and using this equipment is obviously illegal and may even cause air crashes.

Can we use anti-drone guns to force drones to return and capture the drone owner? In theory, of course, but in practice it is very difficult. The simplest countermeasure is that the bad guys rent a villa near the villa complex as a base for launching drones. Even if the bodyguards chase the bad guys to the villa, they cannot enter the villa due to lack of law enforcement power.

Even if they cooperate with the police, they still need a search warrant to enter the villa to search for the drone. Even with a search warrant, it is impossible to prove that the drone owned by the owner flew over the villa complex. In fact, the drone does not need to fly over the villa complex, so in theory, it is not illegal for bad guys to use drones for reconnaissance.

After understanding the twists and turns, Cui Jian became very interested in drones and decided to buy a few to study.

As for the villa complex, the best anti-drone means is drones. Use several drones to control the situation. After discovering a foreign drone, use your own drone to collide with the other drone to achieve the purpose of physical forced landing, and recover the wreckage as soon as possible, leaving the legal issues to the bad guys.

After dinner, they took a walk and found a beautiful meadow. Cui Jian lay down and looked up at the sky, saying that he would use his eyes to monitor the drone. Duanmu, who was standing beside him, knew that he was slacking off, but he couldn't help asking, "What are you thinking about?"

Cui Jian: "Who will kill Xue Bing?"

Duanmu: "Why do you say kill Xue Bing? Instead of kidnapping Xue Bing?"

Cui Jian: "Based on the bodyguard configuration in the villa and the constantly replenished bodyguard capabilities, I can't think of the possibility of kidnapping Xue Bing." Sneaking into the villa to kill someone is possible, but sneaking into the villa to kidnap someone is too difficult.

Duanmu: "So we are hired to fight against the ghosts. As long as the bad guys hire enough ghosts, they can complete the kidnapping."

Cui Jian laughed: "Haha." The traitor can only provide intelligence and assist. However, Duanmu wanted to talk nonsense, Cui Jian let him do it, he didn't care anyway.

I was chatting with Duanmu casually when Duanmu received a call from Bai Qi: "Come to the central pavilion to make tea."

The central pavilion is located in the middle of the equilateral triangle villa complex. Each villa has a walkway connecting the central pavilion. The walkway is two meters wide, with guardrails on the left and right, and a rain and sun shed on top. Shrubs as high as the guardrails are planted next to the guardrails, and there is grass outside the shrubs.

Cui Jian sighed, Xue Bing really knows how to spend money. If it were me, I would turn the bushes into canals. That way, I could swim in the canals, float bottle caps, and raise fish...
