Li Qi knocked on the door, and Xun Xuan opened the door. Tomato free e-book download .// Li Qi enters. Under the guidance of Xun Xuan's eyes, Li Qi took a few steps forward and saw Cao Yu lying on the sofa. Cao Yu wears a white work shirt inside and a weird vest outside. With her hands on her chest, she held a black box the size of two mobile phones, glued to her vest. The box line went around Cao Yu's neck and then connected back to the box.

"Screwdriver!" Li Qi let out a long breath.

Xun Xuan quickly brought the household toolbox, and Li Qi made a silent gesture. Hold your ears close to the box and slowly turn the four screws on the box. This process took a lot of time. The four screws were safely removed, and Li Qi slowly picked up the cover. Inside is a device, and the central device resembles a simple maze toy that I used to play with when I was a child after 75 and 85. A small box with a marble in it, which is sent to the finish line by inverting the toy. Of course, this device is a thousand times more beautiful than holding a toy, and it is also a maze device, but there is no end. There are two marbles in it.

Li Qi straightened up and said: "The mini version of the terrorist bombed the vest, and the explosion hit the chest, with a killing range of three square meters. There are remotely controlled explosive devices. The connection comes in with a balance bomb, and once tilted, two steel balls collide together. A small inductive battery is installed inside the steel ball, which will cause the bomb to explode. I have seen a bomb of this horizontal device once. ”

"What was the result?" Xun Xuan asked in a low voice.

"Exploded." Li Qi grabbed a chair and sat down to observe and said: "To be precise, I haven't seen it, I've only seen the scene and the photos of the bomb." A prosecutor came home with his 12-year-old son sitting motionless with a bomb in his hand. Then he saw the bomb. But instead of a man-bomb vest, a miniature bomb the size of a USB flash drive was hung around the neck. This kind of bomb is also known as a ransom bomb in the industry, and the prosecutor receives a phone call and asks him to destroy the evidence in a case, and they terminate the operation of the bomb. The prosecutor took a picture and asked my team leader for help, and the team leader told him that it was a real guy. So the prosecutor immediately went to destroy the evidence in the case. By the time he got home, his son had already been killed. Because his son's urine shook sharply, the steel balls collided, and a hole was blown open in his throat. ”

Xun Xuan remained calm and asked, "Can it be dismantled?" ”

"Yes. Unless there is an earthquake. Li Qi thought about it: "Or your sister suddenly woke up." ”

"How to dismantle?"

"Freeze the balancer, and brute-force it." Li Qi said: "Liquid nitrogen is used, but ...... The use of liquid nitrogen requires a process, at least a dozen seconds or more. Liquid nitrogen vaporization absorbs a large amount of heat, creating low temperatures. But this part is Cao Yu's heart, and I'm not sure if Cao Yu can bear it. ”

"That is, it can't be dismantled?"

"Yes, but I need time, and the other party won't give me time." Li Qi said: "This kind of bomb is called a ransomware bomb. He can be remotely activated to explode or disarm. That is, once I started defusing the bomb. There is a possibility that the other side will detonate the bomb. ”

"Can you block the signal?"

"I'm not sure about the launcher. If it is a continuous transmission signal, once the signal is blocked. The bomb could be set off. Li Qi stood up and said, "Call the police, I don't have the equipment to be safely dismantled." ”

"Call the police? You said there is a remote control. Well, the police came in plainclothes, but the other party didn't find out. Wouldn't the bomb disposal team still alarm the other side? You do the math, call the police, the police come to the scene to investigate, apply for the bomb disposal team, and the bomb disposal team arrives at ...... How much time does it take? ”

Zhao Yun carried a small travel bag and opened the door by himself and came in: "Two of you." What about a late-night snack? Zhao Yun felt that the atmosphere was not suitable for joking, so he walked to the front and took a look: "Ahhhhh …… That thing can't be a bomb. ”

"yes!" Li Qi stretched out his head and licked the copper wire tied to Cao Yu's neck with his tongue, and said, "There is electricity." "If there is electricity, it means that there is a circuit, which cannot be cut.

Cao Yu's phone rang, Xun Xuan slowly walked to the phone, and pressed the speakerphone: "Hey! ”

A hoarse and gloomy voice asked, "Xun Xuan." Do you remember me? ”

"I don't remember." Xun Xuan replied. The mind thinks quickly about this voice.

"You don't have to think about how to defuse the bomb. Because this is an undefinable bomb. I spent a lot of money. A hoarse voice said, "Xun Xuan, do you want to save your sister?" ”

Xun Xuan immediately replied: "Yes." ”

"Open the window and jump down. The bomb will be disarmed. ”

Zhao Yun said angrily: "Who the are you? "Cao Yu lives on the 22nd floor.

"Go aside." Xun Xuan pushed Zhao Yun away and said, "How do I know that after I jump, you will defuse the bomb?" ”

"I can't provide evidence that you can believe. But the bomb has already been activated. Automatically explodes after an hour. I'll call again in fifty-eight minutes and tell you which window you should jump from, haha. ”

What else did Xun Xuan say, the other party's phone had already hung up.

Li Qi turned his head to look left and right and asked, "What about Sister Lin?" ”

"Not there." Xun Xuan sat in a chair and replied, taking a deep breath.

Zhao Yundao: "I'm more curious, just Cao Yu's skills, why was he drugged at home?" ”

"Who else?" Li Qi sneered at Xun Xuan.

"I don't know the cause and effect yet, you don't fucking fart." Xun Xuan stood up and said angrily.

"This is your own sister." Li Qi said: "You give me a second explanation." ”

"I don't believe it." Xun Xuan said: "She is not that kind of person. ”

"Just because you think so, so your sister is tied to a bomb and lies here."

"Shut up." Xun Xuan pushed Li Qi, and Li Qi pushed Xun Xuan to the chair with a backhand.

Xun Xuan was about to pounce, but Zhao Yun immediately turned over the coffee table to block in front of the two: "Stop, if you want to quarrel, you can wait for Cao Yu to die first." ”

The two sat down and said no more. After a long time, Li Qi said: "This kind of bomb is an iconic bomb, and it is almost impossible to be cloned. For example, although genuine mobile phones will be copied, there are core parts of the technology that cannot be copied. In the field of weapons, there is a backdoor. The meaning is pretty much the same. The user doesn't know the key point, only the creator knows where the backdoor is. ”

Zhao Yun asked, "Who invented this bomb?" ”

"An Eastern European man in his fifties who calls himself Leonardo da Vinci of the bomb world. He was in prison for life. ”

"Prison? So how do you make a bomb? Zhao Yun asked.

"In a Russian prison."

Zhao Yun was stunned. Russia ranks 143 in the world for corruption, only a little better than Afghanistan, Somalia, Libya and other volatile or poor countries. Its total funding is $350 billion per year. Their officials are spending an average of $1 billion a day. In the first half of 2011, officials accepted an average of 300,000 rubles per person, a fourfold increase in eight months. In response, Medvedev said that the fight against corruption is moving on the right path. Saying all this shows that it is not difficult for a felon to be a bomb in prison. What's more, he is an expert figure in an active Russian gangster, and he is treated better in prison than an official.

Now what? The modern bomb is not the simple red and blue line of the nineties movies. In particular, after the large-scale use of bombs by terrorists, various new bombs were developed. Car bombs, vest bombs, pressure cooker bombs...... Endless. In the field of crime, there are more professionals who learn and absorb experience. Police in Western countries generally deal with bomb threats by detonating them. If it is for personal safety and other reasons, the bomb disposal team will be allowed to take risks.

This is a purely imported bomb that, as the gangsters say, is almost impossible to defuse. Such bombs are expensive and low-powered. It won't be the first choice for terrorists.

Zhao Yun came to Li Qi's side, glanced at Xun Xuan, who had been grabbing his hair with his head down: "I think the dog has lost his ability to judge." ”

Li Qi said: "This is his own sister, and I am in charge of it." His sister is going to hang up, and he will play with me. ”

"Does it take to be so selfish to be friends?"

Li Qi didn't speak, picked up the phone and dialed: "Hello, I'm Li Qi, the technical consultant, can you give the phone to Annana." ”

"She's already asleep." The little logistics girl replied.

"Wake up."

“…… Good! The little girl hesitated for a moment, but agreed to come down.

After about twenty seconds, Anana said, "Hey! ”

"I'm Li Qi, can you do me a favor?"

Anana asked rhetorically, "Why do I want to help you?" ”

"Prove that you are still valuable to others."

"......" Anana was silent for a while: "Okay." ”

"You ask the logistics to find a computer, and we'll turn on the video."

……

Anana sat at the head of the bed, a laptop on the covers. In the computer is the picture transmitted by Li Qi. Ananna looked at it for a while and said, "Is there two English abbreviations KJ written on the back of the lid that was opened?" ”

Li Qi picked up the lid of the box on the table and glanced at it and said, "Yes." ”

"The workmanship is fine, it should be genuine. The maker is called Ande Coward Dead Chicken, who, as far as I know, is now in a Russian prison. ”

Li Qi replied: "Can you dismantle it?" ”

Anana also replied: "The coward chicken likes to play clever like nothing more, and he has set several traps in the bomb. The first trap, the condensation trap. Once the bomb temperature drops below minus twenty degrees, the bomb will explode. The second trap, touch the trap. Removing the second screw from the box will activate the bomb. The third trap is the line trap. Assuming it is safe to remove the outside, you will see three to seven lines. It's all fake, cut any bomb and it will explode. ”

"Can it be dismantled?"

"Yes, but with a fair amount of risk." Anana explains, "The only way to do that is to destroy the central circuit board. This board is the place where traps and balances command. To put it simply, the circuit board receives any information from the outside world that gives it a detonation and then detonates the bomb. It is the fuse of this bomb. But because there are several, and even traps, that I may not know about, the risk of defusing this bomb is high. The best way to do this is to cancel by remote control. ”

"But we may not have that much time."

Anana pondered for a moment and said, "I have studied this kind of bomb and have a theory. But because I couldn't find the original, I never experimented with it. I'm not sure what the consequences will be. (To be continued.)
