The world transforms into a game overnight as catastrophic forces sweep across the globe. Monsters ravage every continent, and humanity's only salvation lies in evolving through class advancement and rank progression. Most awaken as powerful mages or elite thunder warriors, racing to accumulate strength before disaster strikes. Ling Zhan defies convention. He selects an unorthodox classless path, channeling every stat point into mana reserves instead of combat attributes. Peers mock his choice—a fighter with no profession, weak foundational skills, and a resource that offers no tactical advantage. Victory seems impossible against specialized opponents who pour decades of knowledge into their chosen disciplines. Then battle arrives, and everything changes. A Level 3 Thunder Warrior trembles before an opponent they believed powerless. An elite Elf Queen watches in horror as limitless mana overwhelms her team's coordination. What should have been easy prey becomes unstoppable force. Ling Zhan's gamble reveals a fundamental truth: unconventional strength transcends traditional advantage, and infinite reserves conquer every battlefield.
