Outside, the sukebans heard and seen the commotion, hurriedly entering the building.
Needless to say, it only took him a few minutes to plop himself in a nearby office chair, respawn his modified CRT monitor and modem, and hack into the building's CCTV system. On screen, there were several sukebans pounding the lobby entrance with the buttstocks of their guns, but one of them shook their head and shot at the glass doors. However, the glass only spiderwebbed, otherwise refusing to budge.
"Oh, you really wanna kill me, do you? Well..." He mused dryly, surfing through several terminals on his modified IBM 5155 and pressing enter. "Try shooting this."
Within seconds, metal security doors lowered in the lobby area; however, once those doors slammed shut, he could no longer see outside, except for a few exterior CCTV cameras. Speaking of footage, his heart slowly sank upon switching to one side of the building, seeing the tank hurriedly barrelling down the street, having just completed a left turn moments ago.
"Oh yeah, I forgot about that." He sighed, but not before noticing the logo, KAISER PMC, sprayed on its turret.
With a loud 'hmm', he scrolled through the spawn menu, a beep followed upon selecting RPG Launcher, his toolgun suddenly transforming into the aforementioned weapon. Plopping into his lap, he inspected the weapon before flicking the laser pointer. Pushing the chair back upon standing up, he leaned out the broken window, carefully raising the modified Swedish launcher on his shoulder and watching the tank rumbling into view below.
Once the tank turned and aimed at the entrance, Min pressed the trigger; a deep BOOP and, a meter after leaving the muzzle, the rocket motor ignited. Within seconds, the modified 84mm laser-guided rocket diaganolly slammed into the tank's engine compartment, a small but reverberating explosion discombobulating nearby sukebans, followed by a smokey explosion from the engine moments later. A fire sprouted through the engine grills, but Min didn't stick around to whoop and watch the rattled crew clamber through the hatches, especially with several sukebans firing at his direction.
Switching to his toolgun, he glanced at the footage again, the lobby still unbreached. Typing into a terminal, the lifts were frozen and every codepad/scanner was rendered inert, automatically locking down the entire building. With a lazy thumbs up, he backpedalled with a skipping gait, fixated on the screen until his right hand felt a doorknob, prompting him to peer behind him, then above him.
"Se-n-se-i Shi-tsu." He babbled, reading the Japanese plaque. "Teacher's Office."
Looking left and seeing a restroom door, he turned right and travelled down a curving hallway, seeing an adjacent Theatre Room and a large classroom across the way, separated by large glass windows. Ignoring a lift on the right, he found himself in an octagonal atrium area, but after a few swivels, he saw a logo on a wall nearby.
"SCHALE..." He pronounced and muttered. "My German is not that great, but I know that means shell. Still, this doesn't make any more sense than before."
Across the atrium straight ahead, there was a double glass door leading to a hangar bay, piquing his curiousity. However, there were no vehicles inside, earning a cringe from him, thus no quick escape. But upon leaving, he took a double look at the logo again, reading the English inscriptions under it.
"Independent Federal Investigation Club..." He said openly. "This place looks more like a government agency than some school organisation. There's just no way...JUST no way."
Glancing around, he saw the other lift, fortunately disabled as it should be. But, something prompt him back to the office, where, upon seeing the CCTV footage, he gasped.
"Oh, no, no, no, no! No, no!" He muttered, watching the metal security doors lift open.
Frantically typing code single-handedly, the computer accepted the commands, but the doors abruptly halted halfway.
"Shit!" He grunted, the terminal crashing and minimising. "Somebody shutted me out."
Opening a new terminal, he punched through the firewalls, but again, the terminal crashed.
"You son of a..." He hissed and shook his head, spawning a duplicate, albeit equally modified, IBM 5155, opening a new terminal.
Connecting to a different jerryrigged modem, clanky keys echoed in the office amid some irritated humming.
"A hacker who is faster than me?" He muttered...curiously? "Well...let's see..."
He tried his luck thrice with the other IBM 5155, he inputted the same commands, again locking him out of the system.
But...
"What?" He uttered, a scowl planted on his face. "It's in the building?"
Finding no security cameras in the office, much to his partial relief, he typed some commands. "Are you kidding me? Where?"
Lo and behold, the CRT monitor, relaying the information from its rectangular compatriots, displayed the origin.
"SCHALE Basement?" He muttered, reading the footage name and analysing the dimly lit room. "But...there's nobody inside."
Crossing his arms, he stared at the footage.
But it then occurred to him...
"Oh, hold on a second. Are you...?" He pondered and casually typed more code, dilating and slacking his lips until they morphed into a blank stare. "Uh, wow...okay. Definitely not a human, but...uh, that's more than a mere firewall."
Dubiously bobbling his head, he peered out the window, using his crossbow to observe the activity below. Fortunately, there were still some angry sukebans trying their luck, but none of them felt his presence overhead. Using a meter stick to draw the steel bowstring, he placed an iron rebar onto the tiller before switching to his toolgun.
Despawning most of his stuff, he grabbed a white backpack and stuffed a modem inside, wires running over his shoulder to the modified IBM 5155 in his hands. Rushing into the hallway, he almost ran into the lifts amid his excitement. Against his better judgement, he unfroze the lift, stepping inside and descending to the ground floor.
