From the Start, I Awakened an SSS-Rank Talent and Became a One-Man Army

This is an era where games and reality have merged, monsters from countless planes are invading, and everyone can change class. Dungeons, secret realms, and otherworldly planes offer countless opportunities. But they are also home to dangerous monsters! Only class holders can stand against them! On the day he changed class, Bai Yi awakened the God-Tier Choice System and received the one-of-a-kind SSS-class profession: Undead Calamity! From that moment on... His skeleton warriors were endless! His death knights were immortal! His bone-white dragons soared across the skies! Even the remains of the gods became his servants! Bai Yi became an army unto himself, commanding a sea of billions of skeleton soldiers! His ruthless undead army swept across countless planes. Who could stand against him? While other class holders were racking their brains just to kill a single boss, Bai Yi had already seized the enemy's stronghold in another plane! While other races were celebrating over capturing a single plane, Bai Yi was already leading an endless sea of skeletons in an assault on the Supreme God! Seated high atop a mountain of corpses, I am the Undead Calamity!
