The cataclysmic BOOM of the weight bar slamming into the Gym floor was more than a sound. It was a declaration. In the observation room, the stunned silence was broken only by the frantic beeping of overloaded sensors. The scientists were no longer looking at a specimen; they were witnessing an event that defied the laws of biology. Artur's display of raw strength had not been an act of cooperation. It had been an act of intimidation. And it worked.
In the days that followed, the dynamic in the Gym shifted. Dr. Thorne and her team abandoned any pretense of control. They became cautious observers, recording data from a safe distance, treating Artur less like a prisoner and more like an unstable force of nature—a volcano that could erupt at any moment.
Artur, in turn, entered a state of hostile cooperation. He performed the tests, but on his own terms. He pushed the limits of what was asked of him—not to impress, but to dominate, to make it clear that he controlled his own body, even if he did not control his own freedom. Each day, he felt stronger. The deep ache in his bones and muscles was being replaced by a dense, vibrant sense of power. It was as if the forge that had ignited in his blood during the "fever" continued its work, silently reshaping him from within.
While Artur pushed physical limits, Dr. Thorne pushed the limits of science in her lab. The results of the ongoing medical tests arriving at her console were, in her own words, "aggressively impossible."
"Look at this," she said to Barros, projecting two X-ray images side by side onto the wall of her office. One had been taken shortly after Artur's rescue, the other just seventy-two hours later. "Here," she pointed to the first image, "we have a comminuted tibial fracture. The bone was shattered. In a normal man, this would take six to eight months to recover—with metal pins and intensive physical therapy. He might never walk properly again."
She then pointed to the second image. "This was taken this morning. The bone isn't just healed. There's no visible fracture line. The bone callus—the natural healing process—never formed. Instead, the bone reinforced itself. And the density… Barros, his bone density has increased by eighteen percent. Not just at the fracture site, but across his entire skeleton. His bones are becoming more like reinforced ceramic than calcium."
Barros studied the images, the soldier in him grasping the tactical implications. "More resistant to impact."
"Far more resistant," Thorne corrected. "And it's not just the bones." She opened another file. "Muscle biopsies. His muscle mass has increased by twelve percent. And he's in a controlled environment, with monitored caloric intake, without the stimulus of real heavy training. This isn't normal hypertrophy. His muscle cells are becoming more efficient at a mitochondrial level. They're producing more ATP from the same amount of oxygen. He's getting stronger and more resilient—even at rest."
Thorne began pacing the room, her mind racing, connecting the pieces. "The Aggressive Immunity… it's not just a defense system. It's a recycling and enhancement system. It didn't just destroy the symbionts—it 'disassembled' them. It analyzed their superior biology, their resilience, their efficiency, and now it's using that information to upgrade the host. Artur's body is proactively adapting for the next fight. He's not just healing from what happened. He's preparing for what's coming."
"You're saying he's becoming like them?" Barros asked, his voice low.
"No," Thorne said, shaking her head. "It's more subtle than that. He's not becoming a monster. He's becoming humanity's answer to them. His body is using the enemy's biological technology to forge human armor. He's becoming, quite literally, his own weapon."
The final test of the week was endurance. Artur was placed on a high-speed treadmill—a monstrous machine designed to push elite DAO field agents to their limits.
"The record is two hours at a speed of 20 km/h, with variable incline," Thorne said over the loudspeaker, her voice metallic and distant. "The protocol is simple. Run until you can't."
Artur didn't respond. He just started running.
The first hour was easy. His body, more efficient, consumed less energy. The second hour—he barely felt it. By the third, the scientists in the observation room began exchanging uneasy glances. By the fourth, the DAO record had been obliterated, and Artur didn't even seem out of breath. His form was perfect, his breathing deep and steady. The only signs of exertion were the sweat glistening on his skin and the vapor rising from his body in the cold air of the Gym.
He could feel the change inside him. It was as if a second engine—more powerful and silent—had taken over. When his legs began to burn, he felt a wave of cold energy spread from his core, soothing the pain, feeding his muscles. The "fever" he had endured—the war in his blood—had left behind not just weapons, but a power plant.
After five hours and forty-two minutes, the treadmill itself began to overheat. The motor groaned in protest, and smoke started leaking from its housing. Thorne, caught between awe and alarm, gave the order.
"End the test! Shut it down!"
The treadmill slowed with a metallic whine. Artur kept running for a few seconds longer before finally stopping, his chest rising and falling, his breathing now heavy—but controlled. He wasn't staggering. He wasn't on the brink of collapse. He was exhausted, yes—but it was the exhaustion of a marathon runner, not of a man pushed to physiological failure.
He bent forward, hands on his knees, trying to catch his breath. A dry, harsh cough shook his chest. He coughed again, harder this time, feeling something rise in his throat. It wasn't mucus. It was something small. Hard.
He spat into the palm of his gloved hand.
Behind the glass, Thorne zoomed in with one of the high-definition cameras. "What is that? Get a close-up."
In Artur's hand, amid a small amount of saliva, there was a fragment. Black. Glossy. Chitinous. It had the shape of a small spike—or the tip of a claw—no more than half a centimeter long. It looked like a shard of obsidian.
Artur stared at the fragment, exhaustion giving way to sudden nausea. He recognized the texture. The color. It was a piece of the monsters.
In the observation room, a deadly silence fell. Barros leaned forward, eyes fixed on the screen.
"What does this mean, Aris?" he asked, tension threading his voice.
Thorne didn't take her eyes off the monitor. Her theory of "recycling" had, until now, been metaphor. Now it was becoming literal—and grotesquely real.
"The infection isn't gone, Barros," she whispered, the realization solidifying into a cold horror. "His body isn't just containing it. It's breaking down the alien genetic material and using what it needs for upgrades. The rest… the waste… it's expelling it."
She looked at Artur on the screen—a man staring at a piece of monster that had just come from inside his own body. He wasn't just the antidote.
He was the battlefield.
And the war, she realized, wasn't over.
It had only changed phase.
