At this moment, he noticed that besides the blue pattern on the gun body, there was a special blue arrow mark, accompanied by the English words “Blue Arrow-Arrow15”.

This should be a custom version of the AR by some firearm company.

The AR-15 was the first rifle to use a 5.56 mm caliber, thus it is also hailed as the pioneer of small caliber rifles. The US military’s M16 is a modified version of it, while the civilian version has removed the selector switch, leaving only a semi-automatic single-shot mode.

Due to the excellent performance of the AR-15, after its patent expired, firearm factories around the world began to replicate it, so various custom versions are not unusual.

But Gu Ji couldn’t understand.

Why does the security of a tech company’s research center need to be equipped with assault rifles, and why do they start shooting indiscriminately, not giving any chance for explanation?

Shooting to kill just for breaking into a research center?

There’s definitely something wrong with Volut!

He immediately took out his phone, unexpectedly finding that the comments in the livestream had already exploded.

[I’m so anxious! What on earth is happening!]

[Please turn on the screen!]

[Holy shit! A real shootout broke out!]

[Is it the police or what, does anyone know where the streamer went?]

[Can the streamer say something? Are they still alive?]

[Art Requires Cruelty: Unbelievable that you survived their private security attack, it seems your identity history is not real, your father’s comrade trained you?]

[Holy crap, the streamer survived?]

[Oh my God! Did you notice, private security! Facial recognition failed! Could it be the streamer infiltrated a corporation and took down the whole company alone?]

[Fuck! This must be the strongest streamer ever, right?]

[Heard the streamer went on a killing spree?]

…

At this moment, due to the intense gunfight just now, the number of people in the livestream had soared to nearly ten thousand.

“What on earth happened at this company? What’s your relationship with them? Why do they spare no effort to kill me as soon as I come in? Are they mistaking me for you?”

Restricted by the rules, Gu Ji didn’t dare to directly say Volut’s name.

But this matter not only concerns the difficulty of future levels but also the truth of his father’s death and the “Crisis Management Game.”

[Art Requires Cruelty: Haha, four questions in one go? Which one should I answer first? Forget it, I choose not to answer any, find and disable the bomb first, then I’ll tell you, watch the time, you only have 17 minutes left!]

[Holy crap, is there an inside story?]

[Shooting the streamer immediately? What kind of company is this, I think it’s a gang, right?]

[Is this for real?]

[Hard to say, without video in the livestream, it’s hard to tell who fired first by sound alone!]

[Whether true or false, for a streamer to take out a group of people alone, what kind of combat ability is this? Special forces? Isn’t this livestream scripted?]

…

Sensitive media also began frantically reporting.

“Breaking news coming up, according to frontline reports, around 8:39 AM on September 8, a mass shooting incident allegedly occurred within a company’s premises, with dense gunfire and explosions audible on-site, involving rifles and high-powered lethal weapons.”

“Currently, one of the individuals involved in the shooting is one of the suspects of this morning’s New York City Subway Line 7 bombing. According to police insiders, there was also an explosion at the USTA National Tennis Center in Flushing Park, with no injuries at the scene. The scheduled US Open match has been canceled, and the New York Police Department has dispatched the Counter-Terrorism Bureau SWAT team…”

It’s not just the media.

The command centers of the Brooklyn Branch, Queens North Command, and NYPD headquarters, as well as the FBI New York Division, were all shaken at this moment, with countless police officers, SWAT, police cars, assault vehicles, and helicopters rapidly moving towards Volut Science and Technology Park!

Meanwhile, Gu Ji himself returned to the security room, picked up his backpack, stuffed the sorted ammunition into his side pocket, and then, holding the gun, searched along the wall for the bomb’s location.

Since the bomber refused to speak.

He could only defuse the bomb first, and then find a way to dig this guy out and interrogate him personally.

As he walked along.

Gu Ji did not see any traces of a bomb or any suspicious objects on the outer wall, so it seemed there was only one method left for demolition:

The implosion method!

Its main principle is to sequentially destroy the load-bearing structures inside the building, causing the exterior components to collapse inwardly, crashing into each other and thus collapsing.

The implosion method is widely used in the United States, but the process is very complex.

Most importantly, multiple point delayed explosions mean there will be a lot of bombs!

“I wonder if there’s still time…”

Gu Ji looked at the time on his wrist, wishing he could make each second last two seconds.

Passing by the laboratory, the researchers saw him and crouched down in panic, begging for mercy!

“It was your security who opened fire on me immediately; I was just defending myself. Don’t worry, I won’t harm any innocent people. Now there may be IED remote-controlled bombs installed in this building. For everyone’s safety, please answer truthfully if you’ve seen any suspicious objects recently, or tell me where the fire safety building plans are!”

Gu Ji said this, but never exposed his back to anyone, and his index finger remained pre-pressed on the rifle’s trigger.

To prevent a sneak attack from a hidden enemy.

Everyone shook their heads, but a female researcher pointed to the restroom at the end of the corridor, “The fire safety building plans are in the restroom!”

Building plans in the restroom?

What kind of operation is this?

But Gu Ji still rushed into the restroom quickly, and indeed, on the wall of the public sink, he found the building’s structural plans.

The reason he was looking for the structural plans was simple.

Demolition can be considered as the reverse engineering of structural engineering. Structures emphasize prevention of progressive collapse, while demolition does the exact opposite.

Control of the collapse process is key to demolition, but actual collapse is a strongly nonlinear process, generally difficult to predict. So if the bomber wants to destroy Volut’s research center, they must precisely place bombs according to the building’s structural load-bearing key points.

“Found it…”

Luckily, Gu Ji not only had blasting skills but also knowledge in earthquake architecture disaster prevention and accident collapse, which is why multidisciplinary learning is beneficial, allowing him to have a certain architectural knowledge base and to form a connection at crucial moments.

He quickly ran to the third office on the first floor.

Two researchers hid away in fear, leaving only Gu Ji to walk to the left wall. This is the main load-bearing wall of the entire building. If the bomber indeed used the implosion method, the crucial bomb must be placed here.

He came to the file cabinet, opened the first drawer, which contained some documents, while the second was locked.

“Someone come and open it!”

Gu Ji didn’t dare to shoot it open, fearing the vibration might trigger the bomb.

After calling out, a middle-aged man with dark brown skin, looking like an Indian, walked over nervously and inserted a key into the lock.

At the moment the cabinet door opened.

The Indian’s face changed suddenly, seeing a large lump of yellow plastic explosives stuck to the back of the cabinet, at least seven or eight kilograms, and as the IED circuit board screen emitted a “beep,” a red countdown light suddenly lit up:

5:00!

[Objective: Successfully find at least two buried bomb areas!]
