The noodles tasted like victory. Xin sat on the hood of a rusty jeep in the Resistance garage, slurping the spicy broth Mei had cooked. His knuckles were bandaged, and his ribs ached with every breath, but for the first time in days, he felt useful.
"Don't choke," Mei laughed, sitting next to him with her own bowl. "The soup isn't running away."
"I missed this," Xin said, wiping his mouth. "Real food. Not energy bars. Not IV drips."
"You earned it," Captain Han said. He was cleaning his rifle on a crate nearby. "taking down that Scavenger leader without using a single Spark... that was impressive, kid. You moved like a soldier."
Xin looked at the dark mark on his chest. It was still silent. "I just did what you taught me. Gravity is a tool, right?"
"Right," Han nodded. "But don't get comfortable. The city is still broken. And without your power, we can't fix the big things."
As if the universe was listening, the emergency lights in the garage flickered and died. A low, grinding noise echoed from the sub-basement—the room where the base’s main power generator was kept.
"That’s not good," Mei said, dropping her bowl. "The generator! If that goes, the shield around the base fails. The toxic air will flood in."
"Grab your gear!" Han shouted, clicking a magazine into his rifle.
Xin grabbed his baton. He didn't have his armor, but he had his legs. They sprinted down the dark concrete stairs, the air getting colder with every step.
When they kicked open the door to the generator room, the temperature dropped to freezing.
Standing over the humming generator was a creature made of pure shadow. It looked like a wolf, but it was the size of a truck. Its eyes were two burning purple holes. It wasn't biting the machine; it was drinking the electricity. Blue sparks were flowing from the generator into the beast’s mouth.
"A Void-Leech," Han cursed. "Bullets won't hurt it. It’s not solid!"
He fired anyway. The bullets passed right through the wolf’s smoky body and pinged harmlessly off the back wall. The wolf turned its head. It didn't growl; it made a sound like tearing paper.
It lunged.
"Move!" Xin shoved Mei to the side.
The wolf’s claw swiped through the air where Mei had been standing. The cold wind from the attack knocked Xin backward into a metal rack.
"Xin, you can't fight it physically!" Mei screamed. "It’s energy! You need energy to hit it!"
Xin scrambled to his feet. He swung his baton at the wolf’s leg. The metal stick went right through the shadow. The wolf looked down at him, bored. It raised a massive paw and swatted Xin like a fly.
CRACK.
Xin hit the wall hard. He felt something snap in his left arm. The pain was blinding. He slid to the floor, gasping for air.
"Xin!" Han yelled, drawing a combat knife and charging the beast to draw its attention.
The wolf ignored the knife. It opened its mouth, preparing to blast Han with the stolen electricity.
Xin watched through blurry eyes. He saw Han standing in front of the beast, ready to die. He saw Mei frantically typing on a datapad, trying to overload the generator to hurt the monster.
I am useless, Xin thought. I am Level 0.
"Incorrect," a voice whispered in the back of his mind.
It wasn't the cold, robotic voice of the Engine. It sounded like his voice. It sounded like the part of him that refused to let go of the window ledge.
"The Engine is not a battery, Host. It is an engine. An engine does not make power from nothing. It needs a spark."
Xin looked at his shaking hands. He thought about the training. The push-ups. The balance beams. The pain. His body was stronger now. His bones were denser. He wasn't a fragile vessel anymore.
I am the spark, Xin realized.
He didn't wait for the system to boot up. He forced it. He focused on his own heartbeat. Thump-thump. Thump-thump. He pushed his anger, his fear, and his love for his friends into that rhythm. He visualized the silver meteor inside his chest spinning.
He didn't ask it to turn on. He demanded it.
SPIN!
A shockwave of heat exploded from his chest. The silence inside him shattered. The Engine roared to life—not with a stutter, but with a scream of raw power.
[Manual Override Detected.]
[Core Reignited.]
[Level 1... Level 3... Level 5 Reached.]
The wolf fired a bolt of blue lightning at Han.
But it never hit him.
Xin was there. He didn't dodge. He caught the lightning. His hand was wrapped in a glove of swirling silver energy—dense, heavy, and real. He crushed the lightning bolt in his palm until it fizzled into sparks.
The wolf stepped back, its purple eyes widening.
Xin stood up. His broken arm snapped back into place with a sickening crunch as the energy healed him instantly. The silver mark on his chest was glowing so bright it lit up the dark room like a flare.
"You like electricity?" Xin asked. His voice echoed, layered with the metallic hum of the Engine. "Have some more."
[Ability Unlocked: Kinetic Cannon.]
Xin pulled his fist back. The air around his arm warped. He didn't just gather energy; he compressed the gravity around his fist, turning his hand into a wrecking ball.
He punched.
A beam of silver force shot from his knuckles. It didn't pass through the shadow wolf. It hit the creature solid.
BOOM.
The wolf howled as the blast blew its chest apart. The shadow mist scattered, trying to reform, but Xin wasn't done.
[Ability Restored: Chrono-Step.]
Xin vanished. He appeared instantly behind the wolf. He grabbed the creature’s tail—which was now solid to his touch—and swung it over his head. He slammed the massive beast into the floor, cracking the concrete foundation.
"Han! Mei! Get back!" Xin shouted.
He jumped into the air. He didn't fly—he wasn't Level 20 anymore—but he hovered there for a second, suspended by the force of his own power. He brought both hands together.
"Level 5... Breakthrough!"
He fired a double blast of kinetic energy. It hit the wolf and pressed it into the ground until there was nothing left but a stain of black grease.
The room went silent, except for the humming of the generator.
Xin landed softly. The glow on his chest faded from a blinding white to a steady, calm blue. He looked at his hands. They weren't shaking anymore.
Han lowered his rifle. He looked at Xin, then at the smudge on the floor. "I thought you said you were back to zero."
"I was," Xin said, turning around. He felt different. Before, the power felt like water flowing through him. Now, it felt like muscle. It felt like it belonged to him. "But I think I just figured out how to turn the key."
Mei ran over and checked the readings on her datapad. Her jaw dropped.
"Xin... the Engine isn't just back on," she said, showing him the screen. "Before, your efficiency was at 40%. You were wasting energy every time you moved. Now? It’s at 98%. You’re not leaking power anymore. You’re... optimized."
"System Reboot Complete," the Engine’s voice returned, clear and sharp. "Welcome back, Host. Current Status: Level 5. Physical Integrity: Enhanced. Ready for instructions."
Xin clenched his fist. The silver light rippled over his skin, responding instantly to his thought. He wasn't the overpowered god who could flip a city. He was something more dangerous. He was a skilled fighter with a perfect weapon.
"We have work to do," Xin said. "The Void-Leech... it didn't come here by accident. It was sent to cut the power."
"Sent by who?" Han asked.
Xin looked at the dark stain on the floor. "By whatever is hiding in the Gray Zone. And now that I have my lights back on... I’m going to go find them."
Xin walked out of the room, the silver mark pulsing steadily in the dark. He was back. And this time, he wasn't just reacting. He was hunting.
