Su Jinyu

Biodata

Power Progression

Background

Su Jinyu is the daughter of a family that owns one of the world's top hundred corporations. Her family's wealth includes a mansion and a private helicopter, while her beauty and combat strength make her a prominent public figure in Lu City 43 96 143.

She falls for Buyu through their online relationship before seeing his full face. Within Mountains and Rivers in Lasting Peace, she handles many of his day-to-day responsibilities and defends him against dissatisfied members. Chen Nian initially regards her as a younger sister because he does not want an online romance, but later recognizes that his feelings have become romantic 26 43 141.

Appearance

• Face and build: A delicate face, slender waist, long eyelashes, and eyes repeatedly compared to stars. She has two dimples when smiling 92 115 246 382.
• Hair: Described as golden after bathing in an early scene, but as black in later battle and bedroom scenes 143 282 502 722.
• Sword Fairy attire: Appears in snow-white robes carrying a three-foot sword, prompting spectators to compare her to an otherworldly Sword Immortal 129.
• Other clothing: Wears an embroidered horse-face skirt when visiting the underground city, a blue-and-white dress for Chen Nian's visit, and a black starry evening dress at the academy mixer 216 253 673.
• Divine manifestation: A red, three-petaled flower appears between her brows when she draws on the Chiyou Sword's power 679.

Personality

Su Jinyu is affectionate and unusually open about her feelings for Chen Nian. She treasures small signs of his attention, uses a blurry photograph of him as her phone wallpaper, and becomes delighted when he initiates contact or remembers an anniversary. Her softer, girlish manner is particularly pronounced around him 43 93 390.

She is also possessive and quick to confront romantic rivals. Her jealousy ranges from verbal sparring with Ye Hongling and Gu Qingyue to an actual sword-and-ice confrontation with Zhao Yixue. Nevertheless, sincere reassurance often calms her quickly, and she asks Chen Nian to put her first when they are together 218 384 674.

Her privileged upbringing leaves her inexperienced with household work, but she is generous toward guildmates and capable of kindness toward perceived rivals. After Shangze Sakura cooks for her, she offers her protection and a place in the Su home. At the academy, she feels guilty over Lin Xiaomeng's distress rather than simply dismissing her 246 269 674.

In battle, she protects others despite personal danger: she shields injured fighters in Lu City, holds an invading army outside Tianping Mountain, and draws a Demon God away from a village to avoid endangering survivors 92 282 678.

Sword Techniques and Formations

Mysterious Lady of the Nine Heavens Divinity

Divinity Takeover

The Divinity can temporarily override Su Jinyu's normal consciousness, replacing her affectionate behavior with cold detachment 144.

• During attempted intimacy, she strikes Chen Nian hard enough that his legendary equipment is credited with preventing a fatal injury 144.
• Chen Nian proposes two possible solutions: Su Jinyu gaining full control of her Divinity, or his becoming strong enough to suppress it 144.

• Su Jinyu subsequently states that her Divinity has not fully recovered 502.
