Stranded twenty years in the past with a defective system, Gu Heng resigned himself to mortal existence. Yet even in his weakness, fate wove his threads through legends. A vulnerable girl he saved rose to become the "Snow White Sword Immortal," legendary across the Three Realms. A dying beast he nursed blossomed into the "Supreme of Ten Thousand Demons." A struggling alchemist received his casual wisdom and emerged as the "Saint Hand of Ten Thousand Medicines." An unassuming disciple he took under his wing transformed into the "Ancient Emperor." With each passing year, the humble mortal's denial grew louder: "I'm merely ordinary, unworthy of such tales." The world, however, saw differently. Every legend whispered the same name. Every immortal recognized the same truth. In their eyes, Gu Heng stood as the singular "Emperor-Saint Master" who shaped destinies while claiming innocence—a paradox that defined an age.
