Slay Only, Spare None: The Guardian's Unholy Righteousness

In an age of chaos, where demons and monsters prowl every shadow and human lives are cheaper than grass, Lin Chu awakens the Guardian System—a power that grants extraordinary rewards for every successful protection mission. But Lin Chu has little interest in conventional guarding. "Who says protection has to mean keeping someone safe? If I slaughter every enemy standing in the way, isn't that the ultimate form of protection?" With that ruthless logic, he hacks a bloody path through the realm. Each slain obstacle earns him Guardian Points, which he pours into mastering techniques like the Return to Void Sword Art, while mission rewards bestow forbidden powers such as the Demonic Seed Devouring Art. As his legend spreads, a fearsome reputation takes hold—the Demon King Guardian, dreaded by humans, immortals, demons, and ghosts alike. A chilling saying echoes across the world: "Secure the Demon King Guardian, and even the Heavenly Court will shatter like dry bamboo before him." Years later, standing atop the summit of both immortal and demonic realms, Lin Chu looks back on the trail of carnage. What began as simple guard assignments has, mission by mission, carved a hidden path toward peace through the very heart of a world consumed by darkness.
