JAYDEForged in the crucible of Xi Corporation’s labs, Jayde—once known only as SN1098—is a genetically engineered super soldier, her body honed to a razor's edge through decades of fighting humanity’s brutal wars. Her rebellion against her creators sparked a desperate battle for her people’s survival, only to end in betrayal and a fiery death on Crypso 3Q3U, her sacrifice shattering the corporate chains binding thousands of GESS lives. Yet death is not her end. Jayde awakens, impossibly, in the tortured body of a young girl on a strange world untouched by the technology she knew—no starships, no replicators, no blasters, only the primal pulse of magic. Bound to an ancient artifact pulsing with secrets, she must navigate a realm of powerful mages, mythical creatures, and lurking monsters, her old instincts clashing with the arcane forces now at her command. Her soul, scarred by battle and betrayal, carries a darkness that threatens to consume or redeem her as she carves a new path.RENRen, the fierce demon king, stands as the last bulwark against his race’s extinction, his heart a furnace of primal fury. To save his people and halt the malevolent Zartonesh’s invasion of the realms, he must venture to the Lower Realm, where the Devil Wars first ignited. His fate entwines with a young woman—Jayde—whose soul, steeped in shadow, stirs the ancient beast within him. Her vast, untamed power could be the key to salvation or the doom of all he fights for, her presence a spark to his fire, a bond that could forge or shatter destinies.AN EPIC JOURNEY OF MAGIC AND REDEMPTIONJayde trades her blaster for a sword, stepping alone into a universe where magic hums like a Centauri war-chant, guided only by a mysterious artifact that whispers of forgotten truths. She journeys across dimensions, learning the art of spellcraft, forging alliances with unlikely companions, and facing enemies born of myth and nightmare. As she grapples with the darkness within her soul—a remnant of her past life’s pain and betrayal—she searches for her true-mate, a bond that could anchor or unravel her. Will she master the magic of this strange world and rise as its savior, or will the shadows she carries bring ruin to all she holds dear?WARNING: This tale unfolds as a slow-burning romance, weaving love and loss through a tapestry of magic, sacrifice, and defiance, as Jayde’s legacy burns brighter than any star.

“I have to squander; otherwise, won’t it be a waste of my parent’s talent at earning money?” Hong Dali answers a reporter’s question matter-of-factly.

Just after the interview ends, Hong Dali opens the Great Prodigal System’s interface and looks at the various good stuff displayed in it. Stroking his chin, he mumbles to himself, “I just need to squander 200 billion yuan more to exchange for the blueprint of the core technology, Engine Destruction, found in the strongest humanoid mecha weapon, Neo Granzon. Looks like I’ll have to work harder!”
