I Am Just a Mortal, Why Do You All Regard Me as a Saint?

Gu Heng transmigrated twenty years ago, only to be cursed with a useless system that left him without a shred of cultivation potential, forcing him to live as an ordinary mortal. Resigned to his mundane existence, he simply tried to do good deeds along the way. When he casually helped a pitiful young girl, she eventually grew into the realm-shaking White Snow Sword Immortal. When he rescued a severely injured stray cat and kept it as a pet, he later discovered it was actually the Supreme Demon Sovereign. A few offhand pointers on alchemy given to a struggling beginner inadvertently created the Ten-Thousand Medicine Saint, and a scrawny female apprentice he took under his wing ultimately ascended to become the ancient realm-conquering Emperor. Gu Heng insists he has nothing to do with any of it, firmly maintaining that he is just a helpless mortal. But the world begs to differ. As the legendary powerhouses of the realm bow before him in utter reverence, the masses refuse to listen to his denials: "Stop making excuses! They all say you are the one and only Supreme Master of the Heavens!"
