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.”

He was supposed to transmigrate to a magic world, but due to an accident, he ended up trapped in a massive library. The system assigned him a task: for every book he read, he would be rewarded with mana stones, until he finished reading all the books. A trillion years later, Daniel finally finished the last book! [Ding, detecting that the host has finished the final book. Calculating system rewards.] [Ding, reward calculation complete. Dispatching rewards. The total number of mana stones the host has accumulated: 99999999...9999.] “Damn, am I that rich now?” [Ding, detecting that the host has completed the task. Loading world...] ... Goddess of Fate: “Daniel, my divine realm needs expansion. Could you sponsor me with some mana stones?” God of Storm: “Daniel, the divine punishment is about to descend. Could you lend me some power to help me get through it?”
