A down-and-out drunkard known as the Crow Sage—his true name, Shen Yanli—carries his late father's legendary 'Seven Falling Stars' martial art and three jars of 'Wangchuan Liquor.' Every technique he unleashes erases a fragment of his memory—and those lost memories are meticulously carved onto crane-bone folding fans by others to preserve them. Burdened by his father's unsolved case, he navigates treacherous power struggles among Han Jingyuan, Murong Lin, and the Prince of Qi—until he meets Gu Zhiwei.
