Gu Ji ignored the bomber's taunt.

He took a closer look at the four screens on the tennis court and chose the east side for two reasons: it was the largest of the four screens; Located above the main stand.

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

Just as Gu Ji was about to leave to check, a noise like waves suddenly poured out around the venue, and dense dots scattered from the passage, and it turned out that the organizer had let the fans in.

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

Come to the east side of the stand.

Some fans are excitedly searching for their seats, unaware of the horror bomb crisis that unfolded in the New York subway this morning, and are completely immersed in the anticipation of the game.

Gu Ji lowered the brim of his hat and shuttled through the flow of people, and after reaching the highest place, he glanced at the security and staff next to him, and quietly came to the back of the electronic broadcast display.

The main display is a staggering 12.8 meters long and 7.2 meters high, spliced together by multiple LED displays, with cement and steel frames held in place behind it.

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

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

Gu Ji hurriedly stepped up.

Because he was wearing a cleaning staff uniform, even if 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, revealing a solid object in the shape of a yellow postal packet underneath, which could be pinched by touching it lightly with his fingers.

It's C4!!

Explosives can be divided into primary explosives, secondary explosives and tertiary explosives according to different sensitivities, explosives with high sensitivity may detonate at a slight bump, and it is difficult to apply them to practice, terrorists need to experience long-distance transportation and installation, they need to use tertiary explosives with very low sensitivity, such as C4!

C4 is a plastic explosive, composed of explosives, plastic adhesives, plasticizers and labeling agents, the main explosive is black sokin, which is a high explosive.

Despite its high power, the C4 is very safe to use, and even if you shoot directly at the explosives, it will not explode, and can only be detonated with a detonator.

On top of that, it is soft and can be rubbed at will, made into a variety of shapes, can easily evade X-ray security checks, and is difficult for police dogs without specific olfactory training to identify it, and is often used by terrorists to cause attacks.

"Hey, what's wrong there?"

Maybe the stay was too long, the security guard asked casually.

Gu Ji didn't answer, but continued to tear the black fixing tape on it to see if he could remove the main bomb from the TV shelf without alarming the audience.

For bomb disposal specialists.

Whenever an explosive is found, the first priority is never to detonate it, as in the movies, to reduce the red and blue lines!

After establishing a full-band signal shield, EOD personnel often use portable X-ray and other equipment to scan to evaluate the power of the bomb, and for less powerful explosives, they can be directly demolished on the spot with water cannon guns.

For bombs that are not suitable for on-site disposal, after being assessed that they can be moved, they are transferred to specialized EOD tanks or pre-dug safety pits to explode pits.

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 domain knowledge in his head.

After carefully tearing off the outer layer of all the fixing tape.

Gu Ji subconsciously gasped.

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

And the weight of the C4 in front of me is probably more than five kilograms, and the explosive power of this level is enough to blow up a two-story small building!

Not to mention that it is also connected to an LED TV, and the high-speed fragments produced during the explosion are even more powerful than ordinary pistol bullets, and if they really smash into the audience, at least hundreds of people will be killed and injured!!

This bomber is a lunatic!

"Hey! What the hell are you doing......

"Evacuate the audience immediately, there is a bomb attack in the venue, go get hydraulic tongs immediately! Notify NYPD EOD Bomb Disposal Team, Quick!! ”

Faced with the second shout of the security guard, Gu Ji was forced to have no choice but to take the second option.

It is simply impossible to dismantle the bomb silently, because the main body of the bomb is tied up by a wire lock, fixed to the steel frame, and forcibly dismantled, which can easily trigger an explosion.

I didn't expect it.

The big-bellied security guard remained stunned after hearing this, and didn't seem to react.

"There's a bomb! Bomb! Hurry up and stop the game and evacuate the crowd!! No time! Fast! ”

It wasn't until Gu shouted several times that he noticed the yellow object on the screen, and the security guard hurriedly picked up the walkie-talkie to report to the upper floor.

【it!】 The anchor found the bomb so quickly? 】

[Awesome, anchor! ] How did he lock on to the bomb location in ten minutes? 】

[God! It really put a bomb on the field, and there is no humanity! 】

[Brothers, isn't the point 'hydraulic tongs'? This anchor probably wants to defuse the bomb, right? 】

[Please open the screen! 】

[It's rude, but I really want to see what the bomb looks like!] 】

[Art needs to be cruel: I didn't expect you to find the bomb so quickly, I hope your luck can always be good!] 】

Just about two seconds after the bomber finished sending the barrage, there was a sudden "drop" sound on the main board of the bomb.

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

4:59 seconds!

[I hear Didi's voice! 】

[The bomb has been activated? 】

[Nima, this terrorist really deserves to die! Streamer, run and let the police take care of these things, you've done enough! 】

[Run, anchor! ] Don't die! Don't let the bomber 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 run away 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 be locked and surrounded by the police, and you will be dead at that time.

Arguably.

The bomber has set him up in a dead end!!

"!"

Gu Ji scolded, turned around and yelled at the security guard: "Don't report and discuss, the bomb will detonate in 5 minutes, immediately broadcast the evacuation of the crowd, quick!" ”

"Ah......h

The security scene was pale, and some viewers who were close 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.

"Everybody, let's go!!"

After scolding, Gu Ji glared and raised his wrist.

There are still 8 minutes left before the location exposure, and there are more than 4 minutes left for the bomb to explode, and there are nearly 4 minutes of escape time in between.

When he tore the tape just now, he took a general look at the detonator circuit, which was not complicated.

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

Gu Ji took a deep breath, abandoning all the influences of the outside world, and in his coffee-colored pupils, there was only the red countdown number that kept flashing.

"Drip, Drip, Drip......"

In the command center, York listened to the bomb countdown in the live broadcast room, and couldn't help but curse the bomber's cruel actions, "Fake! At this time, EOD will not be too late even if it is too late to go by helicopter, so I will immediately connect the person in charge of the organizer of the Arthur US Tennis Court! Immediately!! ”

"Yes! Managing director! ”

The operator said yes while browsing the person's identity information on the screen and making a quick call.

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

【it!】 The anchor is so rigid? Don't run? 】

[This is going to defuse the bomb! 】

[Are Americans so awesome? Will the whole people defuse the bomb? 】

[There are a lot of terrorist attacks there, and I guess I learned from the science and security exchange meetings held in the community or the police station! ] 】

[This is too far-fetched, isn't it?] EOD is not a skill that civilians can master! 】

[I strongly doubt that the anchor has also received special training, otherwise it would not have been so easy to analyze the identity of the bomber before!] 】

[Not to mention anything else, just because he would rather die than run away, even if he is a hero, the police should not arrest him first, but cooperate to deal with the bomber together!] 】

……

Despite the variety of barrages in the live broadcast room, York still understood some key information from them.

Indeed, the young suspect did not act like an accomplice of terrorists.

"Director! The phone number of the person in charge has been connected! ”

"Go to my phone right now!"

York put down the tablet for a while and took out the phone: "Stop the game immediately and evacuate the crowd......"

"Ah......h

"Run!"

"Don't crowd everyone! Watch your step and avoid stampede!! ”

Arthur American Tennis Center Open Court.

Informed by both the big screen and the loudspeaker, the spectators finally learned that there was a bomb attack in the stadium, so they ran desperately to the aisle to escape.

Fortunately, the organizers had prepared sufficient security personnel for this large-scale event, and they barely managed to maintain order.

As for the East End grandstand heights.

Except for Gu Ji, it was already empty.

He wiped the sweat from his forehead, his pupils shrunk like wheat, and he stared at every line on the board.

It's no exaggeration to say that this is the first time since he got "The Crisis Management Game" that he is so serious and engrossed in one thing.

The main thing is that the EOD is not tolerant of any errors.

If you are not careful, you will detonate a bomb and shatter your bones.

The structure of the bomb in front of me is very similar to the remote-controlled IED bomb in the subway, both of which are connected to the electronic detonator by removing the vibration motor through the mobile phone, but it is connected to the timer with one more string.

So, this is a double-detonated bomb.

It can be remotely detonated with a mobile phone signal, and it can also trigger a countdown detonation.

If you want to defuse the bomb without damage, you need to understand the mechanism of the electric detonator and the circuit first.

The detonator is filled with ignition charge, initiating charge and detonating charge, of which the former is ignited by a bridge wire made of nickel-cadmium alloy connected at the front end of two wires.

The so-called remote-controlled detonation.

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

The motherboard connected to the electronic detonator in front of you is a very common "red and blue line mode" in the movie, and there is a PNP transistor in the motherboard, which is divided into emission stage E, base level B, and collector C.

When the voltage of the first two is similar, the current flow to point C will be blocked, but when the voltage difference between the former is greater than 0.6 volts, the current will flow to C, and the circuit will be turned on and the detonator will be detonated.

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

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

Gu Ji held his breath throughout the whole process, for fear that he would accidentally tear off the line and detonate the bomb directly.

Especially the countdown sound of "Dididi", which affects the mentality very much.

Fortunately, "Barron" is young, and his hands are soft and dexterous.

Two wires are successfully separated from the power supply, the positive electrode leads to the red and blue wires, and the negative electrode is connected to the detonator, where the blue wire is connected to the power generation stage E, the red wire is connected to the base B with two resistors of R1 (1kΩ) and R2 (20kΩ), and finally the other wire of the detonator is connected to the collector C.

At this point, the circuit board was completely exposed in front of Gu Ji.

"Hehehe......"

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

The live broadcast room naturally heard it.

[Can you still laugh at this time? 】

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

[Really? How long has it been, a minute and a half? 】

[Art needs to explode: what are you laughing at?] 】

Gu Ji pursed his lips and squinted and smiled: "I'm sorry, I really didn't hold back, I thought that the bomb you set up would be very clever, but I didn't expect it to be so simple, but anyone who knows some common sense of physics circuits in high school understands that the red line seems to be complex and critical, but it is connected with resistors." ”

"Once it is cut, it will reduce the voltage at point B, so that the E and C poles will be turned on, and the explosives will be detonated, and there is nothing on the blue line, directly connected to the E level, so if I cut it off, won't the triode have no power supply?"

The sailors in the live broadcast room heard it in a fog, but there were still some top students who understood the principle.

[It's that simple? It is really the level of physical circuits in the second year of high school in China! 】

[Good guy, listen to your words, like listening to a seat! ] 】

[Hahaha, I have also learned, thanks to the anchor's popular science, now I am also an expert in bomb disposal! ] 】

[Don't think that what the anchor said is simple, when you really hit a bomb, it is difficult for ordinary people to have such a cool head to think about the circuit diagram! ] 】

[666, backhand taunt bomber? 】

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

……

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

Before cutting the wires, he double-checked the board again to see if there were any other hidden dark wires to prevent it from being shaded.

It wasn't until it was confirmed that it was 100% safe that it was decisively attacked.

"Drip ......"

The bomb stopped.

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

Unexpectedly, the bombardier responded at this time:

[Art needs to be cruel: 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 extremely calm by nature; Perhaps, you have also received special training in bomb disposal and are used to seeing explosives, so you are very calm; 】

[I have to say, I'm starting to get interested in you, Barron, maybe you're not as simple as described in the information, I hope you don't die when you face the next bomb, otherwise I'll be sad, oh yes, there are still 5 minutes and 43 seconds left before the location is exposed, I believe the police should have surrounded the arena in advance, good luck! 】

[Barron? Is the anchor called Barron? 】

[This Kunba is too bad! Directly expose the anchor's identity information? 】

[Being an opponent and a referee, how does this Nima play? ] 】

[Won't it be a bomb that has been painstakingly designed, let the anchor dismantle it in a minute, and break the defense, right? ] 】

[Anchor hurry up! We've got your back! The police must not arrest him, or he will die! 】

……

Rumble!

Just as the audience sent a barrage to support Gu Ji, the explosives on the top of the large screen stand suddenly exploded, and Gu Ji hurriedly jumped out of the shelf.

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

Gu Ji gasped for breath, and didn't wait to scold the bomber.

His ears moved, and in the distant sky, there was a sudden "click" sound of a helicopter propeller.

It was surrounded by the New York police.

He decisively used a [drone reconnaissance].

Suddenly, a translucent gray image appeared in the air in front of him, which was a bird's-eye view of the town of Queens, New York, where he was currently located, and the game system intimately helped him mark all the police and police cars in New York City as flashing red dots.

There were about fifteen or sixteen red dots, which were arcing in all directions towards Arthur's US Open court, and even a police helicopter was dispatched!

"It's too late, run!"

This one checked more than a dozen pages of information.,I even found a remote-controlled bomb original map analysis.,The plot is coming to the rhythm.,I feel like I'm in a state.,It's December soon.,Ask for a monthly pass at the beginning of the month!
