Bai Xiao channels the accumulated power of his sub-occupations—'Biological Mecha Master', 'Mystic Explorer', 'Special Hypnotist'—converting endless experience into a million potential points funneled into his primary vocation. The transformation is absolute: the golden ultimate occupation manifests, and he becomes the 'God of Martial Combat'. The world's greatest metropolis drowns in torrential rain. Below, Killing Ghosts clash with Fighters in desperate combat while Metal Mechas and Biological Armors spiral into explosive destruction. Flame consumes blood, violence devours all reason. From a tower's height, Bai Xiao emerges through the downpour, his silhouette carved from shadow and steel. Eyes burning crimson pierce the darkness—controlled fury masking something far more dangerous. His coat tears through wind and rain as he descends. The God of Martial Combat enters the arena. His proclamation shatters the city's peace: "I will slaughter everyone here. Should any dare challenge me, they are welcome to try." Seventy years of tranquility mask a hidden world—one steeped in blood and madness beneath the surface of this glittering, consumption-driven metropolis. Fighters wielding martial mastery wage endless war against Killing Ghosts bound by combat protocols. Metal Mechas pulse with devastating force while Biological Armors—birthed from monstrous genetics—clash in a technological struggle between evolution and obsolescence.
