I Returned as a High School Girl - Chapter 280: Conspiracy (1)

The ordinary 18-year-old Edo, during a nighttime walk, finds himself in a fantasy world where he gains a mysterious power that could shape his destiny.

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.

William Valehart was the absolute—supreme god of all existence. He ruled not a world, not a galaxy, but everything. Unbound by time, space, or death, he was omnipotent, eternal… and alone.By his own will, he sealed away his infinite power and chose to reincarnate. Not in defeat, but in search of something more. He boarded a world-sized ship and cast himself into the unknown, embracing mortality.He died—and awoke again.Reborn in a new universe, aboard the same titanic vessel, William finds himself in Urenus, a galaxy far larger and richer than the Milky Way. It’s here that a portion of humanity—just 5 to 8 percent of its population after conquering over half the Milky Way across millennia of war—has arrived through a now-vanished wormhole. Cut off from the rest of their civilization, they’re stranded, under siege, and barely holding out.Urenus is not unclaimed. Native civilizations, empowered by mana and superior numbers, have rallied against the human invaders. Advanced mech pilots are humanity’s last hope—warriors who push past mortal limits—but they are too few to win.That’s when William Valehart intervenes.With fragments of his sealed power awakening and his god-ship still under his control, he saves a human fleet from destruction—and learns of their fragile, desperate stand.He makes a choice.Not as a god who demands worship.Not as a savior bound by duty.But as a force reborn—who will fight beside them, reshape the war, and carve a place in this new universe.Because he can
