Alex struggles to survive in the colossal MMORPG Ancient World, laboring as a mercenary for five grueling years. The game's existence hinges on AI ZERO, humanity's greatest technological marvel, which unveiled a sprawling planet dwarfing Earth—a realm dominated by mighty empires, powerful syndicates, and enigmatic shadow organizations. Ancient World teems with extinct prehistoric beasts and legendary creatures thought lost to myth. When the United States revealed that AI ZERO and Ancient World originated from an advanced extraterrestrial civilization vastly superior to humanity, the world transformed. The game evolved from entertainment into civilization's cornerstone. Alex entered Ancient World seeking income to sustain his family, but his hopes crumbled under relentless hardship. Then came the impossible: he rewound five years, given another chance at life. Alex understands now that Ancient World transcends a mere virtual reality. Armed with this knowledge and a second opportunity, he rises with renewed determination—growing stronger, climbing toward supremacy, and uncovering the dark secrets buried within Ancient World's origins.
