Shuoyue (朔月, Shuòyuè) is Lan Xichen's sword.

Most of the time, Shuoyue was drawn by Lan Xichen notably to fight Wen Ruohan in the sacking of Nightless City. Afterwards, Shuoyue was primarily used to defend against Nie Mingjue's saber Baxia to save Jin Guangyao. It seems therefore an ironic turn of fate that Lan Xichen would use the same sword to kill Jin Guangyao in the end.
