The third young lady and legitimate daughter of the Yong'an Marquis Residence. Appears foolish and slow-moving to outsiders, but is actually the reincarnated soul of a war god from the apocalypse who died defending a base. Her original body has blocked and knotted meridians that seal her powerful wood-type ability, causing sluggish movements and unclear speech. She is despised by the household and lives in the desolate West Courtyard. She secretly uses her wood ability to purify and enhance medicinal herbs. Her brother Su Jingci is the only family member who still remembers her.
