Nuclear-powered Sword Immortal - Chapter 843 - 704: The Truth Needed_3

Three years ago, she was cruelly abandoned by the man she loved deeply, leaving her to walk down the aisle alone while heavily pregnant. Three years later, she reappears transformed, stunningly beautiful, and says with a smile, “Husband? I don't need a husband.” The man behind her narrows his eyes, his thin lips turning into cold blades, “Qin Yan, try saying that again?”

In a world where strength determines one’s future, William, an orphan with no extraordinary talents, faces a grim destiny—until a brutal attack leaves him clinging to life. Instead of death, he awakens to a mysterious and powerful entity lurking within his mind: the Shadow System, a game-like interface that promises him unimaginable power. But this power comes with dark secrets, and refusing it would mean his death. Forced into a pact with a voice that can hear his every thought, William must navigate a dangerous new reality where shadow abilities and celestial power collide. As he enters the prestigious military academy, his newfound abilities draw both allies and enemies, all while a deadly conspiracy brews in the shadows. With the odds stacked against him, William must unravel the mystery of the Shadow System and decide whether to embrace the darkness within—or be consumed by it. His journey from a bullied outcast to a potential god will challenge not just his survival, but his very humanity. Power always comes at a cost—will William be able to pay the price? “What am I?” William asked the system. The system’s voice echoed in his head, cold and indifferent. “You are nothing.”
