Fifty years ago, human progress stopped. No new equations. No new discoveries. No breakthroughs. For half a century, science lay shackled by an invisible chain, leaving humanity trapped in a golden age that never came. Then came Quincy Enterprise and Interplanetary Network—a revolutionary VR game powered by technology that shouldn't exist. Inside its pods, players command divine magic, touch distant stars, and explore hyper-realistic galaxies. To the world, it’s the ultimate escape. To governments, an unexplainable miracle. To Wyvon Klovis, a burned-out high school physics teacher, it’s a puzzle waiting to be solved. When Wyvon steps into the game as Photon-V, he expects a distraction. Instead, he uncovers a terrifying secret: The game isn't a simulation.

Armed with modern quantum science and a newly awakened divine authority, Wyvon must decipher the Administrator’s sigil, claim the Primordial Creation Gems, and rewrite the rules of reality. The game holds the key to why human science slept for fifty years... and Wyvon is about to wake it up.

Five great continents. Endless wars. In this world, Mana is destiny. It decides who rises as a hero, a king, or a monster. But Tyda never got his chance. Before he could even attend the Guild Selection, his home—Lerin Village on the Eastern Continent—was destroyed by Legion Commander Zed. With no awakened power, he stood alone and sacrificed everything to save his people. To the world, he was forgotten. To Gaiden Minamoto, he became a legend. Born in the same village and blessed with the rarest power—Divine Mana—Gaiden grows up determined to honor Tyda’s will. He leaves the Eastern Continent to join a Guild in the South, while his mentors stay behind to build their own strength. Yet not everyone moved on. Tyda’s closest friends—Maya, Bigolo, Bren, Bram, Glendo, Judy, and Rona—were also trained under Teacher Long. But grief turned into blame, and they became bitter enemies consumed by anger. When Gaiden meets these seniors, still full of pain and rage… what will they do? Will he bring them back from the darkness, or be forced to fight them to the death? And the biggest question of all: If Tyda returns one day… what will Gaiden do? Will he welcome back the hero he admired? Or stand against him if he has become the greatest threat the world has ever known? But one thing is certain: Aurora Guild—once empty, forgotten, and the weakest of all—will rise.

Dying is just data. Revenge is a 10-second delay. In a world ruled by powerful Hunter Guilds and the strict laws of the Hunter Association, Jaxen Vane was nothing more than an E-Rank laborer—disposable bait for corporate meat-grinders. Born with zero combat skills and a comatose sister to support, his only goal was survival. Until the day a routine dungeon raid turned into a deadly corporate cover-up. Trapped by mutated monsters and betrayed by his own vanguard, Jaxen accidentally triggers a late awakening. But his system isn't like the standard blue interfaces everyone else possesses. His is an anomaly—a glitched golden system that loads exactly ten seconds late. Whenever Jaxen suffers a fatal blow, his unique skill, Hindsight Bias, snaps his consciousness back exactly ten seconds into the past. He cannot outrun an A-Rank hunter, and he cannot overpower a C-Rank beast on raw stats alone. But with an endless loop of ten-second do-overs, he can memorize every strike, predict every trap, and turn his own brutal deaths into a flawless strategy board. Forced to hide his world-breaking ability from corrupt guilds, ruthless executives, and a high-ranking investigator who blackmails him into a shadow contract, Jaxen takes up a silver invitation to the National Hunter Academy. Hidden right under everyone's noses, the ultimate underdog begins to silently hoard stat points, master his broken system, and climb the ranks. They think he's just an unpolished gem with a Read button.
