Simulation Game: Crisis Management-Chapter 211 - 121: Professional Bomb Disposal
4:59 seconds!
[I hear the beeping sound!]
[The bomb has been activated?]
[Damn, these terrorists are really despicable! Streamer, run now and let the police handle this, you've done enough already!]
[Hurry, run streamer! Don't die! Don't let the bomber win!]
...
The moment the countdown sound started, the atmosphere in the livestream became instantly tense, and many people urged Gu Ji to run away immediately.
Not only was the bomb about to explode, but there were only a few minutes left before the location was exposed. If he didn't find a way to escape in advance, he would be encircled by the police and die as well.
You could say.
The bomber set up a dead-end for him!!
"Shit!"
Gu Ji cursed and shouted at the security, "Stop reporting and discussing, the bomb will explode in 5 minutes, immediately broadcast and evacuate the crowd, fast!!"
"Ah..."
The security personnel turned pale on the spot, and some spectators near the LED screen heard this information and wanted to take a look closer, but were shouted back by Gu Ji.
"Everyone leave quickly!!"
After scolding them, Gu Ji glared, raising his wrist.
There were 8 minutes left until the location was exposed, and just over 4 minutes left till the bomb exploded, leaving nearly 4 minutes for escape in between.
He had roughly looked at the detonator circuit while tearing the tape, and it wasn't complicated.
There was a chance to break the deadlock.
Gu Ji took a deep breath, blocking out all outside influences, with only the constantly flashing red countdown numbers in his coffee-colored pupils.
"Beep, beep, beep..."
In the command center, York listened to the bomb countdown in the livestream and couldn't help but curse the bomber's cruel actions, "Fuck! Even if EOD takes a helicopter now, they won't make it in time, get me in touch with the person in charge of the Arthur Ashe Stadium now! Immediately!!"
"Yes, Chief!"
The operator responded while browsing through the personnel information on the screen and quickly dialed the phone.
During the wait, York anxiously watched the comments in the livestream.
[Damn! Is the streamer going to face it head-on? Not running?]
[Is he going to defuse the bomb!]
[Are Americans all this badass? Can everyone defuse bombs?] 𝘧𝓇ℯℯ𝑤ℯ𝘣𝓃ℴ𝓋𝑒𝑙.𝑐𝘰𝑚
[They have more terrorist attacks there, so maybe they learned it from community or police safety workshops!]
[This is a bit far-fetched, right? Bomb disposal is not a skill civilians can simply master!]
[Highly suspect the streamer might have had special training, otherwise, he wouldn't have identified the bomber so easily before!]
[Putting everything else aside, just the fact that he'd rather die than run makes him a hero, the police should cooperate with him against the bomber instead of arresting him first!]
...
Despite the various opinions in the comments, York managed to gather some key information.
Indeed, the actions of this young suspect do not seem like those of an accomplice of a terrorist.
"Chief! The call to the person in charge has been connected!"
"Transfer it to my phone immediately!"
York temporarily set the tablet aside, pulled out his phone: "Stop the match immediately, evacuate the audience..."
"Ah..."
"Run quickly!"
"Everyone, don't panic! Watch your step to avoid being trampled!!"
At the Arthur Ashe Stadium.
With notifications on both the big screen and loudspeakers, the audience finally learned that there was a bomb attack inside the stadium, and they raced toward the exits to escape.
Fortunately, the organizers had prepared adequate security for this large-scale event, barely maintaining order.
As for the higher stands in the east area.
Except for Gu Ji, it was already deserted.
He wiped the sweat off his forehead, his pupils narrowing like wheat awns, as he gazed at each circuit on the circuit board.
It's no exaggeration to say, since obtaining the "Crisis Management Game," this is the first time he focused so intensely and dedicatedly on one thing.
Mainly because bomb disposal allows no mistakes.
A slight misstep could trigger the bomb and blow everything to pieces.
The bomb in front of him resembles a remote-controlled IED bomb explored in the subway, activated through a mobile phone by removing the vibration motor connected to the electronic detonator, only this one had an additional connection to a timer.
Hence, it was a dual-trigger bomb.
It could be detonated remotely by mobile signal or set off via the countdown timer.
To safely defuse it, he needed to first understand the powering mechanism of the electronic detonator and the circuit.
The detonator was filled with a sequence of ignition powder, initiating explosive, and main explosive, with the former being ignited by the nickel-cadmium alloy bridge wire at the ends of two connecting wires heating up to trigger ignition.
As for the so-called remote detonation.
No matter what method, the ultimate goal is to connect the circuit to cause the initiating explosive in the detonator to explode, setting off the main explosive.
The circuit board connected to the electronic detonator series is the classic "red-blue wire mode" seen in movies, with a PNP transistor classified into emitter E, base B, and collector C.
When the voltage between the first two is similar, it prevents current flow to point C, but when the former surpasses the latter by 0.6 volts, current flows to C, completing the circuit and triggering the detonator.
Gu Ji's task now was to cut one of the red or blue wires, stopping the current from reaching the collector.
He first located the 12V power supply and carefully picked out the line with his little finger.
Throughout the entire process, Gu Ji held his breath, afraid that accidentally breaking the line would directly set off the bomb.
Especially with the constant "beep beep beep" of the countdown sound, which was disrupting his focus.
Luckily, "Baron" was young, with nimble, handy fingers.
He successfully isolated two wires from the power source, the positive lead connecting to the red and blue lines, while the negative lead connected to the detonator, in which the blue line connected to the emitter E, and the red line along with resistors R1 (1kΩ) and R2 (20kΩ) was linked to the base B, finally, the other detonator wire connected to the collector C.
