These two treasures are the paramount artifacts for protecting Mount Shu, having never left the Sect Summit since the day of their creation.
The east and west treasures, also called the left and right treasures, are the strongest flying swords of the Mount Shu Sect: the Purple Azure Twin Swords—Ziwei and Blue Abyss. However, the Ziwei Sword has been missing for some time, and now only the Blue Abyss Sword remains.
The north and south treasures, also termed the front and back treasures, consist of the South Bright Separation Fire Cauldron and the North Abyss Divine Spear.
