There are rumors in the world that there are three things hidden in the "Broken Sword Tower": the "cold iron" that can break the world's weapons, the "Sword Forging Manual" which records the secrets of martial arts for hundreds of years, and the "Resurrection Pill" that can bring the dead back to life. Twenty years ago, the owner of the building, Yan Li, was surrounded and suppressed by the martial arts for hiding the Resurrection Pill. The Shattered Sword Building was burned down overnight. No bones were left of Yan Li and his wife, except for a daughter, Yan Shu, who was protected by a loyal servant and fled into the quicksands of the Western Regions.
