The Retired Hero is an Extra - Chapter 227 Elemental Gamble

In the 30th century, Tyler Rustel is an eccentric and visionary genius, renowned as a brilliant inventor. His life, however, comes to an abrupt end when a small experimental nuclear reactor explodes in a series of unforeseen events. Yet, death is not the end for Tyler. He awakens in a body that feels both familiar and foreign—a parallel version of himself in a completely different universe.This is not a world of technological progress or orderly civilization. Here, twisted gods roam the cosmos, shaping realities according to their cruel whims. The moral laws that governed his previous world do not exist. This is a magical universe, one marked by brutal betrayals, interdimensional wars, and endless massacres. The balance between the forces that rule this cosmos is fragile, and Tyler finds himself at the center of schemes involving powerful entities and boundless ambitions.However, Tyler is no longer an ordinary man. Upon awakening in this new world, he discovers that a fragment of his technology has survived with him: an advanced artificial intelligence system capable of analyzing, adapting, and enhancing anything, provided it has the necessary data. From magical weapons and arcane spells to alchemical techniques and enchanted jewelry, everything can be optimized under his supervision.Armed with this technological advantage in a universe dominated by magic, Tyler quickly realizes the potential of his unique position. While others struggle to survive, he schemes to conquer. Driven by his sharp intellect and a questionable sense of morality, Tyler embarks on a ruthless campaign to achieve magical supremacy and subjugate all worlds around him. He seeks neither redemption nor alliances. His ambition is clear: to rule everything and everyone as a tyrant, to amass an immense harem of women, and to father one million children to establish his legacy across all realms.

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.
