Crisis Management Game

Gu Ji ignored the bomber's taunt.

He carefully examined the four video screens in the tennis court and finally chose the east side for two reasons: it was the largest of the four TV screens; it was located above the main stand.

These two points alone are enough to cause the bomber to take "special care" of it.

Just as Gu Ji was about to leave to check, there was a sudden wave-like noise around the venue, and dense dots scattered from the passage. It turned out that the organizer had allowed fans to enter.

Some local water friends in New York in the live broadcast room finally confirmed his location.

Come to the east stand.

Some fans are excitedly looking for their seats, unaware of the terrorist bomb crisis that occurred in the New York subway this morning, completely immersed in the anticipation of the game.

Gu Ji lowered the brim of his hat and walked through the crowd. After reaching the highest point, he glanced at the security and staff beside him and quietly came behind the electronic broadcast monitor.

This main display is an astonishing 12.8 meters long and 7.2 meters high. It is spliced ​​up by multiple LED displays and fixed with cement and steel frames behind it.

The first thing he checked was the four corners of the bracket.

Upon closer inspection, it turned out that there was indeed an unknown object wrapped in black tape fixed on it, especially in the center of the back panel of the monitor, a bump nearly four fingers thick.

Gu Ji hurriedly approached.

Because he was wearing a cleaning uniform, even though he stepped on the steel frame, the security guard did not step forward to stop him.

He tore off the black tape on the surface, and a solid yellow mailbox-like object was immediately exposed underneath. It could be pinched by touching it with your fingers.

It's C4! !

Explosives can be divided into primary explosives, secondary explosives and tertiary explosives according to their different sensitivities. Explosives with high sensitivity may detonate with a slight bump, making them difficult to apply in practice. Terrorists need to undergo long-distance transportation and installation. Use very low sensitivity level three explosives, such as C4!

C4 is a plastic explosive, consisting of explosives, plastic binders, plasticizers and tagging agents. The main explosive is RDX, which is a high explosive.

Although powerful, C4 is very safe to use. Even if it is fired directly at the explosive, it will not explode. It can only be detonated with a detonator.

The most important thing is that it has a soft texture and can be kneaded at will and made into various shapes. It can easily escape X-ray security inspections. It is also difficult for police dogs without specific sniffing training to identify it. It is often used by terrorists to stage attacks.

"Hey, what's wrong there?"

Maybe he stayed too long, the security guard asked casually.

Gu Ji did not answer, but continued to tear off the black fixing tape to see if he could remove the main bomb from the TV stand without disturbing the audience.

For bomb disposal experts.

Whenever an explosive is discovered, the first priority option is never to reduce the red and blue lines like in the movie, but to detonate it!

After establishing full-band signal shielding, EOD personnel often use portable X-ray and other equipment to scan and evaluate the power of bombs. For small-power explosives, they can directly use water cannons to defuse them on site.

For bombs that are not suitable for on-site disposal, after it is assessed that they can be moved, they will be transferred to professional explosive disposal tanks or explosion pits dug in advance in a safe place.

Gu Ji didn't have any auxiliary equipment, and he didn't have much time.

The only thing he can rely on now is the tactical knowledge in his head.

After carefully peeling off all the outer fixing tape.

Gu Ji subconsciously took a breath of cold air.

You must know that the theoretical explosion yield of C4 is 1.34, and the explosion speed can reach 8040m/s, which is more than 20 times the speed of sound. More than 400 grams of C4, less than one kilogram, can blow up a heavy truck.

The weight of the C4 in front of me is probably more than five kilograms. The explosion power of this level is enough to blow up a two-story building!

Not to mention that it is connected to an LED TV. The high-speed fragments produced during the explosion are even more powerful than ordinary pistol bullets. If it really hits the auditorium, at least hundreds of people will be killed or injured! !

This bomber is a fucking lunatic!

"Hey! What on earth are you doing..."

"Evacuate the audience immediately. There is a bomb attack in the venue. Get the hydraulic clamps immediately! Notify the NYPD EOD Bomb Disposal Team, quickly!!"

Facing the second call from the security guard, Gu Ji was forced to adopt option two.

It is impossible to dismantle the bomb silently, because the main body of the bomb is tied with a wire lock and fixed on the steel frame. If it is forcibly removed, it can easily trigger an explosion.

Unexpectedly.

The pot-bellied security guard remained stunned in place after hearing this, seemingly unresponsive.

"There's a bomb! Bomb! Stop the game and evacuate the crowd! There's no time! Hurry!"

It wasn't until Gu Ji continued to gesture and shout that he noticed the yellow object on the screen. The security guard was so frightened that he quickly picked up the walkie-talkie to notify the upper level.

【Fuck! Did the anchor find the bomb so quickly? 】

[Awesome anchor! How did he locate the bomb within ten minutes? 】

【God! He actually put a bomb on the field, which is inhumane! 】

[Brothers, isn’t the point of ‘hydraulic clamps’? Could this anchor want to defuse a bomb? 】

[Please open the screen! 】

[Although it is very rude, but I really want to see what the bomb looks like! 】

[Art requires cruelty: I didn’t expect you to find the bomb so quickly. I hope your luck will continue to be good! 】

Just about two seconds after the bomber finished sending the barrage, the bomb's motherboard suddenly made a "beep" sound.

The next moment, a line of red digital countdown appeared on the motherboard’s LED display:

4:59 seconds!

[I heard the sound of Didi! 】

[The bomb is activated? 】

[Nima, this terrorist deserves to die! Anchor, run away quickly and let the police handle these things. You have done enough! 】

[Run away, anchor! Don't die! Don't let the Unabomber win! 】

…

The moment the countdown sound started, the atmosphere in the live broadcast room instantly became tense, and many people were urging Gu Ji to escape quickly.

Not only is the bomb about to explode, but also because there are only a few minutes left before the location is exposed. If you don't find a way to escape in advance, you will still be locked and surrounded by the police, and you will be dead by then.

It can be said.

The bomber set a dead end for him! !

"grass!"

Gu Ji cursed, turned around and yelled at the security guard: "Stop reporting and discussing, the bomb will detonate in 5 minutes, broadcast the announcement immediately to evacuate the crowd, hurry up!!"

"ah……"

The security guard looked pale on the spot, and some viewers who were closer to the LED screen heard this information and wanted to join in the fun to take a look, but they were all shouted back by Gu Ji.

"Everyone, go!!"

After scolding, Gu Ji stared and raised his wrist.

There are still 8 minutes left before the positioning is exposed, and more than 4 minutes left before the bomb explodes, with nearly 4 minutes of escape time in between.

When he was tearing off the tape just now, he took a brief look at the circuit of the detonator. It was not complicated.

It's not that there is no chance of breaking the situation.

Gu Ji took a deep breath and discarded all external influences. In his brown pupils, there were only the flashing red countdown numbers.

"Dip, drip, drip..."

In the command center, York listened to the bomb countdown in the live broadcast room and couldn't help but scolded the bomber for his cruel behavior, "Fak! At this time, it's not too late for EOD to go by helicopter. Get me through to Yaseme right away. Tennis court organizer! Immediately!!"

"Yes! Director!"

The operator agreed while browsing the person's identity information on the screen and dialing the phone quickly.

While waiting, York stared eagerly at the barrage in the live broadcast room.

【Fuck! Is the anchor so tough? Not running? 】

【This is to defuse a bomb! 】

[Are all Americans so awesome? Will everyone dismantle bombs? 】

[There are more terrorist attacks there. I guess I learned it from the science and safety exchange meetings held in the community or the police station! 】

[Isn’t this too far-fetched? EOD is not a skill that civilians can master! 】

[I strongly suspect that the anchor has also received special training, otherwise he would not have been able to analyze the identity of the bomber so easily before! 】

[Let’s not talk about anything else. Just because he would rather die than escape, he is considered a hero. The police should not arrest him first, but work together to deal with the bomber! 】

…

Although there were various barrages in the live broadcast room, York still understood some key information from them.

Indeed, the young suspect did not act like an associate of a terrorist.

"Director! The person in charge has been connected!"

"Transfer to my phone now!"

York temporarily put down his tablet and took out his phone: "Stop the game immediately and evacuate the audience..."

"ah……"

"Run!"

"Please don't crowd! Watch your steps to avoid stampedes!!"

Arthur U.S. Tennis Center Open Court.

Under the double notification of the big screen and loudspeaker, the audience finally learned that there was a bomb attack in the arena, so they ran desperately to the passage to escape.

Fortunately, the organizer had prepared sufficient security personnel for this large-scale event and could barely maintain order.

As for the heights of the East End Stand.

Except for Gu Ji, there was no one there.

He wiped the sweat from his forehead, his pupils shrank, and stared at every line on the circuit board.

It is no exaggeration to say that this is the first time since he obtained the "Crisis Management Game" that he has been so serious and focused on one thing.

The main thing is that there is no room for error in EOD.

If you are not careful, the bomb will detonate and you will be shattered into pieces.

The structure of the bomb in front of me is very similar to the remote-controlled IED bomb in the subway. The vibrating motor is removed and connected to the electronic detonator through the mobile phone, but it has an extra string connected to the timer.

So, it's a double detonation bomb.

It can be detonated remotely using mobile phone signals, or it can trigger a countdown to detonate.

If you want to dismantle bombs without causing damage, you need to first understand the electric detonator and circuit energization mechanism.

The filling ingredients in the detonator are igniting powder, detonating powder, and detonating powder in order. The former is energized and ignited by a bridge wire made of nickel-cadmium alloy connected at the front end of two wires.

So-called remote control detonation.

Regardless of the method, the ultimate goal is to connect the circuit, prompt the detonator to explode, and detonate the main body of the explosive.

The motherboard connected to the electronic detonator in front of us is the "red and blue line mode" that is very common in movies. There is a PNP transistor in the motherboard, which is divided into emitter level E, base level B, and collector C.

When the voltages of the two are close to each other, the current will be blocked from flowing to point C. However, when the former generates a voltage difference greater than 0.6 volts, the current will flow to point C. At this point, the circuit is connected and the detonator detonates.

What Gu Ji has to do now is to cut one of the red and blue wires to prevent the current from flowing to the collector.

He first found the 12V power supply and carefully picked out the lines with his little finger.

Gu Ji kept holding his breath during the whole process, for fear of accidentally breaking the line and detonating the bomb.

Especially the "didi-didi" countdown sound is very affecting the mentality.

Fortunately, "Barron" is young, has soft hands and is very dexterous.

Two wires were successfully separated from the power supply. The red and blue wires were drawn from the positive pole, and the negative pole was connected to the detonator. The blue wire was connected to the power generation stage E. The red wire was connected in series with the two resistors R1 (1kΩ) and R2 (20kΩ) to the base B. Finally, the detonator was connected to another wire. One wire connects collector C.

At this point, the circuit board was completely exposed to Gu Ji.

"Hehehe..."

After taking a serious look, he couldn't help but sneer.

Naturally, the live broadcast room also heard it.

[Can you still laugh at this time? 】

[Has the anchor found a way to crack the bomb? 】

【real or fake? How long has it been? A minute and a half? 】

[Art needs to explode: Why are you laughing? 】

Gu Ji pursed his lips and squinted his eyes and smiled: "I'm sorry, I really couldn't hold it back. I thought the bomb you set up would be very clever, but I didn't expect it to be so simple. Anyone who knows some common sense about high school physics circuits will understand. , the red line seems complicated and critical, but it has resistors connected in series.”

"Once cut, the voltage at point B will decrease, causing the E and C poles to conduct, detonating the explosive. However, there is nothing on the blue wire, which is directly connected to the E level. If I cut it off, the triode will have no power source. Is it done?"

The fans in the live broadcast room were confused, but there were still some top students who understood the principle.

【So simple? It’s really the level of physics circuits for sophomore high school students in China! 】

[Good fellow, listening to your words is like listening to your words! 】

[Hahaha, I also learned it. Thanks to the anchor for popularizing science, now I am also a bomb disposal expert! 】

[Don’t think what the anchor said is simple. When a bomb is really encountered, it is difficult for ordinary people to have such a calm mind to think about the circuit diagram! 】

[666, backhand taunting the bomber? 】

[The anchor is so wild, he is not worried about the bomber blowing him up! 】

…

Gu Ji didn't care whether the bomber responded or not, and took out a small knife from his pocket.

Before cutting the line, he carefully checked the circuit board again to see if there were any other hidden lines to prevent being exposed.

Don't make a decisive move until you are sure it is 100% safe.

"drop……"

The bombs stopped.

Gu Ji was finally able to breathe a sigh of relief.

Unexpectedly, the bomber responded at this time:

[Art requires cruelty: Although this bomb is very simple, it is difficult for ordinary people to deal with it calmly within 5 minutes. Maybe you are a genius and are naturally extremely calm; maybe you have also received special training in bomb disposal and are used to seeing explosives , so very calm and calm;]

[I have to say, I am starting to become interested in you, Barron. Maybe you are not as simple as described in the information. I hope you will never die when you face the next bomb, otherwise I will be very sad. , Oh, by the way, there are still 5 minutes and 43 seconds before the positioning is exposed. I believe the police should have surrounded the arena in advance. I wish you good luck! 】

[Barron? The anchor’s name is Barron? 】

[This Kumba is too bad! Directly expose the host’s identity information? 】

[Being an opponent and a referee at the same time, how can you do this? 】

[Isn’t it a bomb that was designed so hard that the anchor can dismantle it in one minute and break the defense? 】

[Anchor, run away! We all support you! The police must not arrest him, or he will die! 】

…

boom!

Just as the audience was sending barrages in support of Gu Ji, the explosive on the top of the big screen stand suddenly exploded, and Gu Ji hurriedly kicked off the stand.

Following a series of explosions, the huge LED display finally fell down.

Gu Ji was breathing heavily, but he didn't even have time to curse the bomber.

My ears twitched, and in the distant sky, there was suddenly a "dah-dah" sound of a helicopter propeller.

It was the New York police siege.

He decisively used [Drone Reconnaissance] once.

Suddenly, a translucent gray picture appeared in mid-air in front of him. It was an aerial view of the town in Queens, New York, where he was currently located. The game system thoughtfully helped him mark all the police and police cars in New York City as flashing red dots.

There were about fifteen or six red dots, surrounding the Arthur US Open stadium in an arc from all directions, and a police helicopter was even dispatched!

"It's too late, run!"

I checked more than ten pages of information on this one, and I even found an original picture of a remote control bomb to analyze. The plot has picked up the pace, and I feel like I'm in a good state. It's almost December, please give me a monthly ticket at the beginning of the month!
