Female supporting character, originally the alternate personality of Yun Weiyue that emerged after Yun Weiyue fainted upon discovering her maid's betrayal. She possesses all of Yun Weiyue's memories but has a completely opposite temperament—loathing evil and unable to tolerate betrayal. After Yun Weiyue's death, she was controlled by Shen Moyuan and forced to collect Literary Qi, accumulating Baleful Qi from killing innocents. She hid Yun Weiyue's soul in a portrait scroll. She chose the name Yun Qingsu from Yun Weiyue, derived from a poem meaning her fragrant form is pure enough to topple cities.
