Wake up to a zombie apocalypse, slay mutated senior and awaken god-tier selection system.

The peaceful modern world collapsed in the blink of an eye the moment countless people woke from their sleep, as a brutal and sudden doomsday descended without any warning. A mysterious strange virus swept across the entire region instantly, turning ordinary humans into ferocious, bloodthirsty zombies that lost all rational thought. Meanwhile, all local flora and fauna underwent bizarre and terrifying mutations. Ordinary plants grew wildly into aggressive predatory vegetation, while common animals evolved into violent mutated beasts, turning every corner of the city into a deadly hunting ground filled with hidden dangers. Amid the sudden global chaos, college freshman Su Hao was trapped on the narrow cafeteria rooftop together with a haughty and arrogant senior student. Cut off from all escape routes and surrounded by the chaotic campus below, the two were forced to huddle in the cramped safe space, clinging to a fragile hope of survival. Yet disaster struck quickly; one of their trapped companions was unfortunately infected by the pervasive virus. The victim soon lost self-awareness and completed a terrifying transformation into a ferocious zombie, becoming an immediate lethal threat to the remaining survivors on the rooftop. Faced with the sudden crisis, Su Hao showed extraordinary calm and decisiveness. Without the slightest hesitation or naive mercy, he took swift action to eliminate the transformed threat and secure the temporary safety of the rooftop. This resolute life-or-death action accidentally triggered a legendary almighty selection system, a powerful cheat that belonged exclusively to him. The system unlocked countless generous reward options, allowing him to freely pick from various tempting benefits including massive wealth and stunning female companionship. Aware of the cruelty of the end times, Su Hao firmly rejected all superficial wealth and beauty temptations. He insisted on prioritizing self-improvement, choosing every reward that could boost his physical quality and combat strength. Equipped with newly unlocked powerful weapons and enhanced abilities, he ventured bravely into the perilous ruined campus and city. He hunted rampant zombies, screened for trustworthy survivors to gather as allies, and accumulated strength steadily. Step by step, he built a powerful and cohesive survival team, gradually carving out his unshakable survival dominance and forging his own glorious path in the desolate doomsday world.
