Master of the Strange Game

A bizarre game suddenly descends upon reality. Registering grants supernatural powers, while those who refuse become prey for ghosts and monsters. In his previous life, Lin Mo was foolish and stubborn, refusing to register, leaving himself defenseless. Faced with rampant ghosts, he was unarmed, mocked and scorned by others, and ultimately hanged to death by a ghost in public, dying in endless humiliation and pain. His soul reborn, he returns to five years before the strange game's arrival. The world is still peaceful, ghosts have not yet set foot on earth, and everyone is oblivious to this apocalyptic catastrophe. Seizing this once-in-a-lifetime opportunity, Lin Mo activates the strange game ahead of time, frantically clearing dungeons, slaying fierce ghosts, and leveling up, training in secret for five years to grow stronger. Five years pass in the blink of an eye, and the strange game arrives as scheduled. When the whole world is frantically registering and struggling under the fangs of ghosts, Lin Mo is already a top-tier powerhouse standing at the world's summit. Those who once mocked him now kneel at his feet begging for mercy. Holding game administrator privileges, he sweeps away ghosts, tames countless eerie objects, and gradually unifies the strange game, establishing his own ghost domain kingdom. — Description from novelcodex.org
