The Grand Princess, upon her departure, ultimately left Ran Qingchen "Ruqing Sword" and "Western Region Heartless Flower".
As the treasured sword that could only be worn by the Sect Leader of the South Sea Holy Sect, it had not been returned since Jiang Wan left the sect, and had later been placed within the Imperial Palace, with the South Sea Holy Sect's several attempts to reclaim it proving fruitless.
After Li Guanshi had achieved great success in his cultivation, he also lost the drive to reclaim it.
The treasured sword, originally named "Cutting Love Sword," had the formula of the South Sea Holy Sect's "Cutting Love Skill" engraved on its blade.
The first line went: Threads of emotions, once cut, clear the mind; the vast river of love, once crossed, reveals true nature.
