“Primum non nocere.”

In the year 2139, the world changed. Fundamentally and irrevocably.

Everything happened too quickly. The sky cracked like an egg and armored dinosaur-like monsters lurched out of the fissure. The split, though small at first, quickly widened. Within a few short hours, these beasts had overrun the world.

Countries, even those who had been enemies for centuries, sounded a global alarm. Political differences were cast aside as humans scrambled to find a solution—any solution—to what became known as the Great Disaster 1.0.

Human experimentations began, first in reluctance, then in earnest. As days turned into weeks and weeks into months, failure rates remained high. Desperate for results, global authorities started turning a blind eye to how experimental subjects were sourced.

Countless victims were kidnapped and trafficked to state-run laboratories. Shi Tian was but one of them. But unlike those who died nameless, in pain, and unrecognizable, he had the fortune of surviving after being injected with humanity’s last hope—an integrated chip.

Except… the chip remained dormant. It seemed that certain circumstances must be met before the chip could be activated. What those circumstances were, even the scientists in charge could not answer.

Kai’s life was small—coffee-stained mornings, cracked recipes, and a system in his head that tweaked toasters and dough like it was nothing. Then the sky shattered. Aliens—Skraiths, jagged and brutal—invaded, tearing his city apart with green-glowing weapons and relentless claws. Superhumans rose to fight back, fire and lightning blazing through the chaos, but Kai’s world crumbled with them.Hiding in his apartment, Kai stumbles on blood—human and alien, smeared on his wall after a superhuman battle. His system, once just a tinker’s tool, awakens, offering him a choice: mimic their powers, temporary and wild, through the blood itself. Desperate, he takes it—stealing pyrokinesis, then electrokinesis, then kinetic energy, each power burning through him, fading fast. But it’s not enough. Armed with a humming Skraith weapon and a body tougher from alien blood, Kai joins a ragtag crew of enhanced fighters—Liv, Rylan, Jace, and Tucker—scraping to survive in a warzone where every shadow hides death.As Skraiths swarm and the city burns, Kai’s system pushes him deeper, analyzing, integrating, crafting minor enhancements—durability, strength, sparks of power that could make him a target or a savior. Government factions, rogue scientists, and the aliens themselves start sniffing around, drawn to his strange tech and blood-stolen abilities. By the time Kai crafts his first super-powered enhancement—an artificial strength boost—he’s no longer just a tinkerer. He’s on the edge of something bigger, something dangerous, where blood and sparks could forge a hero—or break him entirely.In a world unraveling, Kai’s fight for survival becomes a desperate race to master his system, outrun the Skraiths, and confront the truth: the power he’s chasing might destroy him—or remake the world.
