CNiQIYI

Li Lianhua is a quiet, weathered healer who lives in a crooked old tower and solves puzzles for a living. Few know that he was once the greatest swordsman in the martial world, now weakened by poison and hiding under a new name. When an eager young man named Fang Duobing insists on becoming his apprentice and a string of murders begins to point at the past, Lianhua is pulled back into the world he tried to leave. Old rivals, old secrets and old debts are waiting.
