The convoy left Basa Air Base shortly after sunrise.

Twelve vehicles rolled out through the eastern gate in a disciplined column, passing between concrete barriers, guard towers, and coils of razor wire still marked with stains from the recent battle. The lead vehicle was an M1117 armored security vehicle, its turret slowly scanning the road ahead while the gunner kept both hands near the weapon controls. Behind it came two JLTVs, three cargo trucks carrying engineers and tools, two fuel-support vehicles, a mobile repair truck, another pair of armored escorts, and a final M1117 guarding the rear.

Chandrika sat in the second cargo truck near the middle of the convoy, wedged between two other auxiliary soldiers and a stack of equipment crates secured with cargo straps. Her rifle rested across her lap, muzzle pointed down, safety engaged. She kept one hand loosely around the grip, not because anyone had told her to, but because the world outside Basa had a way of punishing people who relaxed too much.

The road beyond the base looked different from what she remembered during her first rescue.

Back then, every street felt like a death sentence. Cars had been abandoned in the middle of lanes, bodies lay rotting under the heat, and infected wandered wherever sound drew them. Now the main route out of Basa had been cleared. Wrecks were pushed to the shoulders, checkpoints had been built along key intersections, and patrol markers were painted on walls and road signs.

It still did not feel safe.

It only felt controlled.

A soldier sitting across from her checked his magazine for the third time in ten minutes. His name was Ramos, a former delivery rider who had joined the auxiliary forces six months ago. He had a habit of humming whenever he was nervous, and he had been humming since the gate opened.

Chandrika glanced at him. "You’re doing that again."

He looked up. "Doing what?"

"Humming."

"I’m not humming."

The soldier beside him, a woman named Lira, did not even open her eyes. "You are. You’ve been doing it since breakfast."

Ramos looked offended. "That’s my breathing."

"Then your breathing is out of tune," Lira said.

A few soldiers chuckled, and some of the tension inside the truck eased. Chandrika smiled faintly, though her fingers remained wrapped around the rifle. She tried to look calm, but her stomach was tight, and every bump in the road made her attention snap toward the rear flap of the truck.

One of the engineers seated farther inside the cargo bed leaned forward. He was older than the soldiers, with gray hair beneath his helmet and a thick folder of documents tucked inside a waterproof sleeve. His name was Engineer Salcedo, one of the men assigned to inspect the refinery’s mechanical systems.

"You young people look too serious," he said. "This is a good mission."

Ramos blinked. "Sir, we’re going into Bataan."

"Yes," Salcedo replied. "To look at a refinery."

"With zombies."

"Everything has zombies now." The engineer shrugged as if that solved the matter. "But a refinery is still a refinery. You protect us, we inspect the equipment, everyone goes home. Simple."

Lira finally opened one eye. "Engineers always say things are simple right before something explodes."

Salcedo laughed, not offended in the slightest. "That is because people forget to listen to engineers."

The truck shook as it rolled over a damaged section of road. Chandrika steadied herself against the side rail and looked through the gap in the canvas cover. The convoy was moving through a stretch of highway lined with abandoned buildings, some burned, others reclaimed by vines and grass. Far beyond them, the mountains stood under the morning haze.

Bataan waited somewhere ahead.

The thought made her grip tighten.

She knew why the refinery mattered. Everyone did. Basa had fuel reserves, but those reserves were not infinite. Every aircraft sortie, every armored patrol, every generator, every supply convoy consumed fuel. The base had survived because it had military power, but military power needed logistics, and logistics needed fuel.

If they could secure the refinery in Limay and restore even part of its operations, everything would change.

Vehicles could move farther.

Aircraft could fly more often.

Factories could run longer.

Farms could expand through mechanized equipment.

It was not only a military objective.

It was a lifeline.

The convoy radio crackled inside the truck. Captain Herrera’s voice came through the vehicle speakers, calm and firm. "All units, maintain formation. Drone overwatch reports light movement two kilometers east, no direct threat. Keep weapons on safe unless ordered otherwise."

Ramos immediately looked toward the road. "Light movement means what?"

Lira leaned back again. "It means light movement."

"Infected?"

"Probably."

"How many?"

"If they wanted us to know, they would have said."

Ramos stared at her. "You’re not comforting."

"I’m not your mother."

Chandrika almost laughed, but the sound died when the convoy slowed.

The truck’s engine rumbled lower as the entire column reduced speed. Outside, the lead M1117 turned its turret slightly toward a cluster of abandoned houses near the roadside. The gunner did not fire, but every soldier inside the cargo truck became alert.

Chandrika lifted her rifle slightly.

Not aiming.

Just ready.

Through the rear opening, she saw shapes moving between the houses. Three infected staggered into view, their clothes reduced to torn strips and their skin darkened by dirt and rot. One wore what remained of a school uniform. Another dragged one leg behind it, ankle twisted at a wrong angle.

The convoy did not stop.

The lead vehicle’s gunner fired a short burst.

BRRRT.

The three infected collapsed before they reached the road.

Nobody cheered.

The convoy continued forward as if nothing happened.

Chandrika stared at the bodies until the truck turned and they disappeared from view. Her chest felt tighter than before, and she realized she had been holding her breath.

Lira noticed.

"First time seeing them outside a wall?"

Chandrika hesitated before nodding. "First time since Okada."

Ramos looked at her more carefully. "You were rescued from Okada?"

"Yes."

His expression shifted. "Damn. I heard about that operation."

Chandrika adjusted her glasses, feeling a little self-conscious. "It was a long time ago."

"Still," Ramos said. "That place was bad."

She did not answer.

For a moment, the sound of gunfire in a hotel hallway returned to her memory. Flickering lights. Bodies on the carpet. Doors opening. People screaming from the far end of the corridor. Adrian standing behind her group, calm despite the chaos, telling everyone to move.

Back then, she had barely understood what was happening.

Now she wore a uniform and carried a rifle.

The thought felt strange.

Not bad.

Just strange.

The convoy continued through Dinalupihan, moving past abandoned storefronts and intersections marked by old signs. Several buildings had been searched before, judging from the painted symbols on their walls. Green circles marked cleared structures. Red crosses marked hazardous zones. Yellow arrows pointed toward roads secured by previous patrols.

Basa’s reach was expanding.

Slowly, methodically, but undeniably.

After another hour on the road, the landscape began to change. Industrial structures appeared in the distance. Storage yards, pipeline supports, utility poles, and old access roads became more common. The air smelled faintly different too, carrying traces of salt, rust, and something chemical beneath the ordinary scent of vegetation and dust.

Engineer Salcedo leaned forward, eyes bright despite the danger.

"We’re close."

Ramos looked at him. "You sound happy."

"I am," the engineer said. "Do you know what a functioning refinery means?"

"Fuel?"

"Fuel, yes, but not only fuel." Salcedo tapped the folder against his knee. "Diesel, gasoline, jet fuel, lubricants, asphalt, petrochemical feedstock. Even partial restoration gives us industrial breathing room. Right now, Basa survives on what we recover. With refining capacity, we start producing again."

Chandrika listened carefully.

It was easy to forget that wars were not won only by rifles and aircraft. Someone had to repair roads. Someone had to power generators. Someone had to refine fuel and maintain engines and move food from farms to storage depots.

Civilization was not one big thing.

It was thousands of small systems working together.

The radio crackled again.

"All units, this is Herrera. We are approaching the outer perimeter of the Limay refinery complex. Drone overwatch shows scattered infected activity inside the facility. No large horde detected, but visibility is limited around storage tanks and internal structures. Weapons tight. Engineers remain inside vehicles until security clears the first checkpoint."

The mood inside the truck changed at once.

Even Salcedo became quiet.

Chandrika checked her rifle the way the instructors had taught her. Magazine seated. Chamber ready. Safety engaged. Her hands trembled slightly, but not enough to stop her from doing each step properly.

Lira noticed and gave her a short nod.

"That’s normal," she said.

"What is?"

"Being scared."

Chandrika looked at her.

Lira smiled faintly. "If you’re not scared out here, you’re stupid. Just keep your hands steady."

The convoy slowed again as the refinery came fully into view.

The facility rose ahead like a dead industrial city.

Massive cylindrical storage tanks stood behind weathered fences, their white paint stained by years of neglect. Steel pipe racks ran between processing units like the ribs of some sleeping metal beast. Tall distillation towers pierced the sky, rust streaking their sides, while old warning signs swung gently from gates half-covered in vines.

It was enormous.

And eerily silent.

Chandrika had seen skyscrapers, hotels, casinos, and malls before the outbreak. She had never stood near something like this. The refinery did not feel like a building. It felt like a machine large enough to reshape the future.

The lead M1117 stopped near the main access road.

Captain Herrera’s voice came through the radio. "Dismount security teams. Establish perimeter. Engineers wait for clearance."

The rear flap dropped.

Heat and sunlight rushed into the truck.

Chandrika stood with the others and stepped down onto cracked pavement, boots hitting the ground with a dull thud. Around her, soldiers formed up quickly, rifles raised but not yet aimed. The armored vehicles took positions near the entrance while the cargo trucks halted behind them.

Somewhere inside the refinery, metal clanged.

Everyone froze.

The sound echoed between pipes and storage tanks, sharp enough to cut through the morning air.

Ramos whispered, "Please be wind."

Another clang followed.

Closer this time.

Chandrika raised her rifle toward the gate.

From behind a cluster of rusted pipes, several infected began to emerge.

Not many.

A dozen at most.

But enough to remind everyone that the refinery was not empty.

Captain Herrera’s voice came over the radio, calm as ever.

"Security teams, engage."

Chandrika took a breath, placed the stock firmly into her shoulder, and remembered Adrian’s voice from the range.

Relax.

Breathe.

Don’t yank the trigger.

She aimed at the nearest infected and squeezed.

The rifle cracked.

The infected dropped.

For half a second, she stared in surprise.

Then Lira fired beside her, and the rest of the line opened up. Controlled bursts snapped across the refinery entrance, cutting down the infected before they could cross the gate. Within seconds, the road was clear again.

Ramos looked toward Chandrika.

"Nice shot."

She swallowed, still breathing hard.

"Thanks."

Behind them, Engineer Salcedo slowly peeked from the truck.

"Is it clear?"

Captain Herrera did not even look back.

"No."

Salcedo immediately ducked back inside.

Lira smiled.

"Smart engineer."

The soldiers advanced toward the gate.

Chandrika moved with them, rifle raised, heart pounding, boots crunching over broken glass and gravel. Ahead of her, the massive refinery waited in silence, full of shadows, rust, and the promise of something far more valuable than victory.

Fuel.

If they secured this place, Basa would not merely survive.

It would grow.

And for the first time since leaving the base, Chandrika felt the weight of the mission settle fully on her shoulders.

She was no longer just someone Adrian had rescued.

She was part of the force protecting what came next.
