Inherited Martial Saint Cultivation, You Call This the Apocalypse?

I emerged from three years of seclusion as a peak Martial Saint—only to find my manor in ruins and the world overrun by demons. My vital energy surges like an ocean, my Imperial Qi commands heaven and earth, yet the apocalypse I face makes my century of inherited cultivation feel insignificant. The monstrous hand that once annihilated the original Martial Saint now threatens all of Blue Star, and before that unknown entity, even I am merely a stronger ant. The system's mission is clear: slay the owner of that hand. I just wanted a quiet life, but fate has other plans.
