The memory of the blueprint was seared into his mind, a constellation of impossible data on the grey, weary backdrop of the camp. Hepatitis Immunity. It wasn't theory; it was fact, a line of code waiting to be compiled into living tissue. The System's interface, a constant, translucent overlay on reality, seemed to pulse with a patient, waiting energy.
He had done it to himself. The burning heat of the shift had faded, replaced by the System's acknowledgement and a profound, unsettling sense of otherness. He was immune now to a plague that had ruled his life. The ability was no longer hypothetical. It was personal.
And it had to be utilized.
He was walking, his legs carrying him with a resolve his brain hadn't yet fully embraced. The camp was stirring now, a symphony of discord. The aroma of newly baked flatbread could not mask the underlying odor of open sewage and sickness. He saw it all through the new eyes of the System. A man with a limp—[Status: Old fracture. Poorly healed. Genetic predisposition for low bone density.] A child with a rash—[Pathogen: Sarcoptes scabiei. Easily treatable.] An old woman coughing—[Status: Chronic bronchitis. Environmental factors.]
A gallery of solvable problems. A world of broken code waiting for a programmer.
He didn't know where he was going until he was there. Standing outside Leila's shelter. The picture of Amina, small and yellowed, dead on her pallet, flashed in front of him. He had acted then in a blind panic, a surge of power he didn't understand. He had reversed the damage. But he hadn't dealt with the root cause.
He listened to the soft hum of a child humming inside.
He parted the cloth doorway. Leila was sitting on the floor grinding coffee beans. She glanced up, and her face, which had been etched with a constant grief, now held a tentative, bewildered joy. Amina was beside her, playing with a ragged cloth doll. Her complexion was clear, no longer the terrifying jaundiced yellow but a healthy olive. Her eyes were bright, focused on her doll.
"Dawud," Leila exclaimed, her voice warm with delight. "Look! Look at her! It is a miracle from Allah."
Amina glanced up and smiled shyly at him.
The moment ought to have been one of pure happiness. It was. It was, however, a happiness overshadowed by a terrible, cold lucidity. The miracle was not yet finished. The hepatitis virus was gone from her body, but her genome was still weakened. The door it had entered was still wide open. She was from an area where the virus was endemic, in the water, in the soil, hand to hand. It was only a matter of time.
He could prevent it. He had the map.
His mouth went dry. This was not editing himself. This was another person. A child. Without her permission. Without her mother knowing.
"She looks good," Dawud said, his voice gruff.
"She is," Leila said, her eyes sparkling. "She ate a whole breakfast. She has not vomited once." She dropped her voice. "The people… they talk. They say you have a gift. That you laid your hands on her and prayed."
Dawud drew back a step. That was a tale he couldn't handle. A dangerous one. He was not a holy man; he was a tech. A hacker.
He knelt down, his heart thudding against his ribs. "Amina, ya habibti, can I take your hand?"
The little girl looked up at her mother, who nodded encouragement, then extended her small hand. Dawud took it gently. Her skin was warm and delicate. Engadget.
He didn't need to touch her to enter the System, but the contact helped him focus. He closed his eyes.
[Genome Visualization.]
The world fell away. He was back in the Nexus again, but Amina's genetic code filled the center. A beautiful, shining helix, still aglow with the new, System-assisted repairs to her liver cells. It was the genome of a survivor. And it was unguarded.
He called up the saved design. The Hepatitis Immunity code glowed beside her natural code. A perfect match, a key to a lock she was born with.
[Execute Preemptive Genetic Defense: Hepatitis B Immunity. Y/N?]
The prompt floated, impersonal and logical. Yes or No. Safety or risk. The surety of future infection measured against the unknowable consequences of a permanent rewrite.
He imagined his mother's face. He heard her gasping for breath. He thought of the hundreds of other children in this camp, playing in the muck, drinking the tainted water, living on borrowed time.
His hesitation was a betrayal. Who was he to play God? But who was he to step aside, having the power to prevent an abomination, and do nothing out of fear? Was that not a greater sin?
The logic of the System was pure. The edit was stable. The gain was absolute.
He took a trembling breath. His hand trembled around Amina's.
For you, he thought. For all of you.
Do."
He whispered the word, a solemn invocation and a terrible affirmation.
The process this time was faster, more efficient. His will was more focused. He wasn't fighting the System; he was commanding it.
He saw in his mind's eye the exact order on the sixth chromosome of Amina—the gene for the HLA protein that the virus used as a point of entry. The System's focus was laser-like. He saw a single nucleotide being edited. Then another. A minute, precise alteration. A redesign of the lock so that the viral key would no longer be able to enter.
It happened in just a heartbeat.
[Edit: Successful. Hepatitis B Immunity: Installed.]
He opened his eyes. The real world rushed back. The hum of the camp. The smell of coffee. Leila's questioning smile.
Amina blinked. "That tickled," she said, laughing.
Dawud released her hand, his own hand trembling. He half-expected her to transform, for some outward indication of the transformation to take place. But there was none. The miracle was internal. It was in the nucleus of all her cells. A silent guardian.
He had done it. He had edited another human being.
The weight of what he'd done fell on him, crushing and terrible. He felt a sudden, deep fatigue, deeper than any he'd ever known. It was not just physical. It was the energy cost of the rewrite, yes, but it was also the psychic cost of the decision. The System's status bar wavered.
[Energy Reserves: 9% - Critical.] [Neural Load: 41% - Elevated.]
He needed to eat. He needed to sleep. The magic came at a price, and he was its fuel.
"Dawud, are you alright?" Leila's smile faded to concern. "You're so pale."
"I'm… I'm just tired," he stuttered, making himself stand. He felt lightheaded. "I am glad that Amina is safe.".
He stumbled from the shed into the blinding sunlight. He leaned against the searing corrugated iron wall, trying to steady his breathing. He had crossed another threshold, far more significant than the first. He had moved on from healing to enhancement. From cure to prevention.
He looked down at his hands. They looked ordinary. They were not. They were instruments of creation and alteration. With a touch, he could alter the story of a life.
A wave of sickness passed through him, half exhaustion, half awe, half horror. He had just ensured a little girl would never suffer what his mother had. It was the most beautiful thing he had ever done.
And the worst monstrosity.
For he knew, with a certainty that chilled his soul, that this was only the beginning. The blueprint was there. The hepatitis redesign was one project. What about tuberculosis? Malaria? Cholera? What about the genetic codes for cancer? For heart disease?
The world was a tapestry of suffering, and he held the needle and the thread.
He pushed off from the wall and began the walk home, his legs shaking beneath him. The whispers started up behind him again, but they were changed now. They were no longer just a miracle. They were of him.
"There he is…" "…touched the child,and she was healed…" "…a gift from God…" "…tabib.doctor…"
He was no doctor. He was something new. Something the world had no name for.
He reached his home and climbed onto the roof, seeking the empty sky. He needed to escape the prying eyes, from the weight of their expectation.
He collapsed onto the worn mat, the sun warming his skin. The System interface persisted, a permanent part of him. He called up his status.
[Energy Reserves: 8% - Critical. Biomass conversion required.] [Available Functions: Limited.]
He was drained. Empty. He had poured himself out into coding a new future into a little girl's genes.
Lying there, a final, soft notification arrived, not from the central System, but from a lower, more analytical sub-program. It was a report.
[Projection: Subject Amina Hassan.] [Edit: Stable. Heritable.] [Conclusion: Offspring will inherit Hepatitis B immunity.]
The words struck him like a blow.
"Heritable.".
It wasn't just about Amina. He hadn't just saved one life. He had altered a bloodline. He had introduced a new trait into the human species, one that would be passed down, generation upon generation.
He hadn't just done a rewrite.
He had begun an evolution.
And he was lying on a rooftop in a refugee camp, dizzy with hunger, because he had forgotten to have breakfast.
The absurdity of it all was overwhelming. He started to laugh, a dry, scraping noise that was nearly a sob. The laughter stopped, and he discovered that he was staring into the vast, blue emptiness of the sky.
The spiral had reversed beneath his will. Light had flooded her veins. And nothing would ever be the same again.
