The bunker trembled as emergency lights flickered back to life.
Smoke drifted through the shattered doorway, but the gunfire had stopped.
Ethan Cross stepped forward cautiously, shielding Aria and Maya behind him.
A lone figure emerged from the haze.
He was tall, dressed in a charcoal-gray tactical jacket, his face partially hidden beneath the shadow of a hood.
His hands were empty.
"So," the stranger said calmly, "the famous Ethan Cross."
Ethan didn't lower his guard.
"Who are you?"
The man smiled faintly.
"Someone who has been looking for you."
Before Ethan could ask another question, the stranger lunged.
No weapons.
Just speed.
Ethan sidestepped the first strike, but the man's spinning elbow grazed his shoulder—the same shoulder that had been wounded days earlier.
Pain shot through him.
The stranger followed with a sweeping kick.
Ethan leaped over it and answered with a straight punch aimed at the jaw.
The man blocked it effortlessly.
For several seconds, the two exchanged rapid blows—punches, elbows, knees, and precise kicks—each testing the other's skill rather than trying to end the fight.
Maya instinctively reached for her rifle.
"Don't," Ethan said without taking his eyes off his opponent.
"This is between us."
The stranger's expression changed.
"You've gotten slower."
Ethan smirked.
"You've gotten predictable."
The stranger attacked again, driving Ethan backward toward a concrete pillar.
At the last moment, Ethan caught his wrist, twisted it, and used the attacker's momentum to throw him onto the floor.
The man rolled smoothly back to his feet.
Neither had gained the advantage.
Aria watched in amazement.
She had never seen two people move with such discipline and precision.
No wasted movement.
No panic.
Only skill.
The stranger suddenly stopped fighting.
He took one step back and raised both hands.
"You still have your edge."
Ethan frowned.
"You know me."
"I trained with you."
Silence filled the bunker.
Ethan searched the man's face.
Then realization struck.
"...Noah?"
The stranger pulled back his hood.
It was Noah Mercer, Ethan's former training partner from the Intelligence Directorate.
Years ago, Noah had disappeared during an undercover operation and was presumed dead.
"I heard you were killed," Ethan said.
"I let everyone believe that," Noah replied.
"Why?"
"Because Shadow Protocol had infiltrated the agency. I couldn't trust anyone."
Maya lowered her weapon but remained cautious.
"If you're alive, why reveal yourself now?"
Noah's expression grew serious.
"Because you're running out of time."
He turned to Aria.
"They're not hunting you just because of your past."
"They're hunting you because you're the only person who can unlock the final stage of Shadow Protocol."
Aria's heartbeat quickened.
"I don't even know what that means."
"You will."
Noah reached into his jacket and placed a small metal keycard in Ethan's hand.
"There's an abandoned research facility outside the city. Everything starts there."
Before Ethan could ask another question, a faint metallic sound echoed through the bunker.
Click.
Everyone froze.
Noah's eyes darted toward the ceiling.
"They're here."
"Who?" Maya asked.
Noah answered quietly.
"The real hunters."
The lights went out once more.
In the darkness, footsteps echoed from somewhere deep within the bunker.
Slow.
Measured.
Closer with every second.
No one could see who was approaching.
Then a calm, unfamiliar voice broke the silence.
"You've all come farther than expected."
A single flashlight flickered on at the far end of the corridor, revealing only the silhouette of a person standing perfectly still.
The figure took one step forward.
Then another.
Before the face could be seen, the light snapped off.
The footsteps stopped.
Silence returned.
Ethan tightened his grip on the keycard.
For the first time in years, he felt something he rarely experienced.
Uncertainty.
