The facility was worse up close.
Eight hours of observation had stripped away the initial shock of its size and replaced it with a detailed, clinical understanding of exactly what they were dealing with. Jae-min had spent every minute of those eight hours with his spatial awareness extended, mapping the compound's interior in three dimensions, counting heartbeats, tracking movement patterns, and building a mental model of the facility that was more accurate than any blueprint could provide.
The facility rose from the ten-meter snowpack like a castle keep, its lower levels completely buried, only the upper two floors and the roof visible above the white expanse — only rooftops breaking the white plain in every direction, the industrial district reduced to dark stumps poking from a frozen sea. The snow-clearing operation must have been enormous — a ring of excavated perimeter at least fifty meters wide, the snow cut away in sheer walls of ice that glinted blue-white in the gray light. Enemy patrols moved along these snow walls, their tracks creating a network of paths through the cleared zone, the guards using the snow trenches for cover and concealment as they circuited the compound.
It was a converted pharmaceutical plant — that much was clear from the layout. The central building had been the main manufacturing floor, a cavernous space with high ceilings and reinforced concrete walls that had been subdivided into smaller chambers using prefabricated partitions. The eastern wing had been the laboratory complex, with clean rooms, operating theaters, and a basement level that extended at least two stories below ground. The western wing was residential — barracks, a mess hall, what looked like a recreation area with salvaged furniture and a heating duct that kept the space marginally above freezing.
And the security was professional.
Not scavenger professional — not the haphazard, improvised defenses that Jae-min had encountered in every other compound and settlement across frozen Manila. This was planned. This was funded. Guard towers with overlapping fields of fire. Perimeter patrols on a twelve-minute rotation. Infrared sensors mounted at intervals along the wall — pre-freeze military surplus, still operational, powered by the generator farm. Concertina wire in three layers. A vehicle checkpoint at the main gate with a mechanical barrier arm and an observation window reinforced with steel plating.
Two guards at the gate. Four on the perimeter. Two in each tower. And an unknown number inside — Jae-min's spatial awareness could detect body heat through walls, but the facility's own heating systems created interference that made precise interior counting difficult at this range. His best estimate was sixty to eighty hostiles total.
"They've got at least a platoon's worth of manpower,". — Rico, said, said
"Employees," Ji-yoo repeated. The word dripped with contempt. "They're employees who strap university students to tables and pump them full of experimental compounds."
"Whatever they are, they're dangerous." Rico lowered the scope. His face was tight behind the respirator. "Head-on assault through the main gate is suicide. Even with Ji-yoo and Yue, we'd be fighting uphill against a fortified position with overlapping fire lanes and superior numbers."
"What about the river?" Aiko suggested. She was sitting beside Mei's wheelchair, her own tablet synced to the schematic Mei was compiling from Jae-min's spatial data. "The facility sits on the Pasig riverbank. There might be a water intake or drainage tunnel on the northern side."
Jae-min had already checked.
He shook his head. "The northern wall runs right to the river's edge. There's a drainage outflow — pipe, about a meter in diameter — but it's been sealed with a steel grate and an infrared sensor mounted directly above it. They've thought of it."
"Then we need another way in." — Rico, voice quiet
"There's a maintenance tunnel on the western side," Jae-min said. "Runs from the exterior wall to the central building's sub-level. It's how they move supplies and personnel between the underground labs and the surface. It's not guarded on the outside — they rely on the wall and the infrared grid to cover that approach."
"If we can get past the wall without triggering the sensors." — Mei, voice quiet
"That's the challenge." Jae-min paused. His spatial awareness was still extended, still feeding him data in a continuous stream of pressure, displacement, and thermal signature. "The infrared grid has a gap. Small one. On the southwest corner, between two sensor posts, there's a dead zone about four meters wide. The sensors overlap everywhere else, but at that specific point, there's a structural pillar that blocks the infrared line-of-sight."
"How do you know that?" — Rico, eyes searching
"Because the guard who patrols that section steps through it every rotation." Jae-min's eyes were still closed, his awareness focused on the facility. "He's doing it deliberately. Taking a shortcut through the dead zone to shave thirty seconds off his circuit. He's been doing it for the last three hours. Every twelve minutes, like clockwork."
Rico's eyebrows rose above his respirator. "He's slacking off on patrol."
"He's human. They all are." Jae-min opened his eyes. "No matter how professional the setup, the people running it are still just people. They get cold, they get tired, they get bored, they get lazy. That's the crack. That's where we go in." — Jae-min, toneless
Ji-yoo was nodding slowly, her dark eyes sharp with understanding. "The colonel's right. This isn't a scavenger operation. But it's not a military fortress either. It's a corporation playing soldier. The infrastructure is real. The people are soft." She turned to Jae-min and smirked. "Also, Oppa, your tactical briefing voice is doing this thing where you sound like a discount action movie narrator. It's very inspiring. I'm motivated. I'm going to assault a building because of your voice."
"My voice is fine."
"Your voice sounds like someone described leadership to you over the phone and you're doing your best impression."
Rico pinched the bridge of his nose. This was the Han twins in their natural habitat — nonsensical bickering as a coping mechanism.
"Soft people with automatic weapons and guard towers,". — Rico, muttered, muttered
"Soft people who stand in four-meter dead zones because their feet hurt,". — Ji-yoo, replied, replied
"Then we take away the walls." — Jae-min, quiet certainty
The group looked at him.
"One hundred C4 charges," he continued. "We don't use them all at the end. We use some of them now. The maintenance tunnel gets us inside. The rest of the charges go on structural points throughout the facility — load-bearing columns, foundation joints, gas lines, the central HVAC system. We plant them during the assault. Not before. During."
"That's a combat engineering schedule," Aiko said slowly. Her engineer's mind was already running the calculations — charge placement, propagation timing, structural failure patterns, blast radii. "You're talking about entering a hostile facility, planting high explosives in active combat zones, and detonating them while we're still inside."
"Yes." — Jae-min, brief and cold
"That's insane." — Aiko, a simple word
"Yes." — Jae-min, immediate
Aiko stared at him for a long moment. Then she opened her tablet and started drawing a schematic, her stylus moving across the screen with the speed of someone whose hands had been trained by years of precision work. "I'll need structural load data. The central building's columns, the sub-level supports, the generator housing, the underground lab walls. If we hit the right points in the right order, the collapse will be progressive — top-down, cascading inward. It'll take the underground labs with it."
"Can you design the sequence?" — Rico, eyes searching
"I already have most of it. The charges are modular — compact C4 with remote detonators. I can program them to fire in any sequence I want, with variable delay intervals. If Jae-min can give me the column positions and load-bearing data, I can have the propagation pattern ready in two hours." — Aiko, matter-of-fact
Jae-min closed his eyes. Extended his awareness to maximum range.
The facility opened in his mind like a wireframe model rendered in pressure and density — every wall, every column, every corridor, every room, every human body. He could feel the structural load-bearing elements by their mass. The columns were the heaviest — reinforced concrete cores with steel rebar, each one dense enough to register as a distinct spatial signature even through three layers of partition wall. The foundation joints were denser still, where the building met the ground in massive blocks of poured concrete.
"Fourteen primary columns in the central building," he reported, his voice steady. "Six secondary supports in the eastern wing. Eight in the western wing. Foundation joints at the northeast and southwest corners — those are the weakest structural points. The HVAC main trunk runs north-south through the ceiling space between the central building and the eastern wing. Aluminum ducting, thin-walled, easy to breach."
Aiko's fingers flew across her tablet. "Fourteen primary, six secondary, eight western, two foundation joints, one HVAC trunk. That's thirty-one structural charges. We keep sixty-nine in reserve for the underground levels, the guard barracks, and the wall breach."
"The wall breach is two charges,". — Jae-min, said, said
"You're placing the wall charges yourself?" — Rico, eyes searching
"I am. My spatial awareness lets me position them within two centimeters of the sensors' detection threshold. No one else can do that with the precision we need." — Jae-min, the precision of a tactician
Rico didn't argue. He'd seen what Jae-min could do with void tears — the millimeter precision, the surgical placement of objects in three-dimensional space, the ability to fold a piece of C4 into existence inside a spatial pocket and deposit it on a target surface without ever crossing the space between. If anyone could plant explosives four centimeters from an infrared sensor without triggering it, it was the man who could bend reality with his bare hands.
Mei looked up from her tablet. Her face was pale — the cold was getting to her despite the wheelchair's heating system. Her fingers were stiff, moving slower than usual, but her eyes were sharp and focused. "I've got the distress signal isolated. It's coming from the eastern wing, sub-level two. The signal is automated — a life-support system with failing power. Whoever set it up wanted it found." — Mei, matter-of-fact
"Life support,". — Ji-yoo, said, said
"Maybe. Or for the equipment. Pharmaceuticals need temperature control. If their underground freezers are failing, they'd have a reason to broadcast a distress signal." — Mei, matter-of-fact
"Or it's a trap,". — Rico, added, added
"Maybe all three,". — Jae-min, said, said
He paused. The wind shifted, carrying the faint chemical smell again — antiseptic, formaldehyde, something sharp and biological that turned Jae-min's stomach even through the respirator's filter.
"We move tonight at twenty-two hundred. Final briefing in two hours. Get rest while you can."
The group dispersed. Mei wheeled herself to a sheltered corner behind a concrete barrier, where the wind was partially blocked. Aiko went with her, pulling a thermal blanket from her pack and draping it over Mei's legs. Rico settled against the warehouse wall with his rifle across his lap, his eyes half-closed but never fully shut. Ji-yoo moved to the far end of the collapsed warehouse, found a spot with a clear line of sight to the facility's western wall, and sat down with her back against a frozen I-beam.
Yue hadn't moved.
She stood at the edge of the warehouse, her marble eyes fixed on the facility. Her thermal suit was black, her blade was black, her face was a mask of compressed granite. She hadn't moved in over an hour. Her breath crystallized in front of her face and fell to the frozen ground like snow — a steady, metronomic rhythm of white particles catching the gray light.
Jae-min walked over to her.
"Yue."
She didn't turn. Her eyes stayed on the facility. On the guard towers. On the loading dock. On the warm, pulsing glow of the central building where her students were being held behind steel doors and locked wards and God knew what else.
"I need you focused,". — Jae-min, said, said
"I'm focused." — Yue, cold
Her voice was flat. Dead. The voice of a woman who had compressed every emotion she possessed into a single, diamond-hard point and was using it to hold herself together.
"Your students are inside,". — Jae-min, said, said
"Don't." — Yue, monotone
The word was a blade. Jae-min stopped.
"Don't remind me why I'm here," she continued. Her voice hadn't changed pitch. Hadn't changed volume. It was the flattest sound Jae-min had ever heard from a human throat — flatter than ice, flatter than silence, flatter than the frozen ground beneath their feet. "I know why I'm here. I've known since the camera footage. I've known since I saw Maria Santos's face on that table with tubes in her arms and her eyes open and empty and staring at nothing. I've known since I saw Joshua Dela Cruz's body — his dead body, Jae-min — being dragged by two guards through a corridor like a bag of laundry."
Her hands were shaking. Not visibly — the tremor was so slight that Jae-min only detected it through spatial awareness, a micro-vibration in her forearms that propagated through her fingers and dissipated at her fingertips. She was holding herself still through sheer force of will, the way a dam holds back a flood.
"I will be focused," Yue said. "I will be precise. I will kill every guard between me and those students without hesitation and without mercy. And when it's over — when we've pulled them out or we've burned the building down around the ones we couldn't save — I will process what I'm feeling. But not now. Not before the mission. Now I work. That's all I have left. Don't take that from me."
Jae-min said nothing for a moment. The cold pressed in. The wind drove ice crystals across the frozen ground between them and the facility. A guard in the northern tower shifted position. The infrared sensors hummed at frequencies beyond human hearing.
"Okay,". — he, said, said
Yue nodded. Once. The shaking stopped.
Behind them, the facility's lights flickered. A patrol moved along the northern wall, their footsteps crunching on frozen gravel. The infrared sensors swept their invisible arcs. The generators rumbled in the compound's heart. And somewhere beneath the frozen earth, in laboratories that Jae-min's awareness could feel but not clearly see, machines were running.
Twenty-two hundred. Eight hours and counting. — Jae-min thought, the steadiness an act of will — a clock ticking inside his chest where the heating core couldn't reach
Hold on. We're coming. — Jae-min thought, directed at the warmth signatures behind those walls — a promise he had no right to make, spoken to people who might already be beyond saving
He walked back to the warehouse. The cold bit through the seams of his thermal suit, finding the gap between his glove and his wrist, between his collar and his neck, between the layers of aerogel insulation that Aiko had so carefully assembled. The heating core pulsed against his chest — warm, cold, warm, cold — a rhythm that had become as familiar as his own heartbeat over the past eight hours.
Ji-yoo was waiting for him. She was sitting with her back against the I-beam, her knees drawn up, her arms wrapped around them. Soulcleaver hummed behind her sternum — he could feel its gravitational resonance even from three meters away, a low, subsonic vibration that registered in his spatial awareness like a second pulse.
"That was intense,". — she, said, said
"She needed to say it." — Jae-min, with the detachment of a chess player
"Did you need to hear it?" — Ji-yoo, eyes sparkling with mischief
Jae-min sat down beside her. The frozen concrete was cold even through the thermal suit's padding. Their shoulders touched. "I needed to understand where she is. She's not processing. She's not grieving. She's not feeling anything at all. That's more dangerous than rage."
"Rage I can work with," Ji-yoo agreed. "I understand rage. But that—" She gestured vaguely toward the facility. "That's something else. That's a woman who's decided that feeling is a luxury she can't afford. And she's right. But the bill comes due eventually."
"After the mission." — Jae-min, quiet
"After the mission," Ji-yoo repeated. She paused. Her dark eyes found his. "Oppa. The students. The ones in the footage. Some of them were already—" She stopped. Swallowed. "Some of them weren't moving."
"I know." — Jae-min, voice flat
"We might be walking into a building full of bodies. Not prisoners. Bodies." — Ji-yoo, voice warm with dark humor
"I know." — Jae-min, immediate
"Can you do what needs to be done? If we can't save them?" — Ji-yoo, voice dripping with glee
Jae-min looked at the facility. At the guard towers. At the lights flickering behind frosted glass. At the plume of exhaust rising from the generator farm, the only visible breath in a city of the dead.
"Yes." — Jae-min, brief and cold
Ji-yoo held his gaze for a long moment. Then she leaned her head against his shoulder, the way she had when they were children and the world was too loud and too big and too frightening for two small bodies to carry alone.
"Okay,". — she, murmured, murmured
The cold pressed in. The facility waited. The generators rumbled. And in the shadows of a collapsed warehouse in Pasig City, a brother and a sister sat together and watched the compound where everything they feared was waiting to be found.
