Su Yu

Biodata

Power Progression

Background / History

Su Yu joined the First Saint Sect a few years before the events of Chapter 50. She became its Saintess and the sole disciple Liu Ziyan had accepted after searching for hundreds of years. Her position made her a likely future successor to the sect leader, giving her influence over officers whose cultivation exceeded her own 24 44 50.

Her secret objective is to obtain the Yin-Yang Evil Demon Art. Although Hong Yue and Lin Mo initially only suspect her of espionage, Su Yu’s private thoughts later confirm that she is an infiltrator. She fears execution if Liu Ziyan discovers her identity and punishment from her own side if she returns without the art. Her employer is not identified; the Yin Yang Sect is Lin Mo’s conjecture, not an established affiliation 33 35 50.

Appearance

• Face: Exceptionally beautiful, with lingering youthful immaturity and a habitual innocent smile 9 34.
• Hair: Thick, lustrous black hair tied in a high ponytail that reaches her calves 9.
• Eyes: Bright silver eyes; they turn blood-red while she contemplates Lin Mo’s unexplained advancement 9 32.
• Clothing: Blue-green and white attire at her introduction 9.
• Bearing: Graceful movements and a refreshing fragrance 9 23.

Personality

Su Yu presents herself as cheerful, approachable, and unconcerned with rigid status distinctions. She greets Lin Mo voluntarily and allows him to bow rather than kneel. Later, she calls him a friend and speaks sympathetically about the lack of rights afforded to servant disciples, though these later overtures also serve her effort to recruit him 9 43 50.

Behind this manner, she is cautious and calculating. After spotting Lin Mo near her secret correspondence, she hesitates to question him because doing so might alert him. When arranging his arrest, she refuses responsibility for his punishment and insists that the Enforcement Hall handle the case itself 21 44.

Her fixation on the Yin-Yang Evil Demon Art can disrupt her composure. Learning that Liu Ziyan taught it to a servant but refused her leaves her openly agitated; once she learns its partner-binding drawback, she restores her innocent smile almost immediately 34.

Her attraction to Lin Mo is not entirely feigned. She privately finds him handsome and later recognizes a distinctive charm in him that she does not perceive in other servants, disciples, deacons, or elders 9 43 44.

Abilities & Skills

Cultivation Talent and Perception

• Possesses a quasi-ninth-grade spiritual vein and reaches late Foundation Establishment by eighteen 9 32.
• Detects that Lin Mo has entered Foundation Establishment and recognizes how extraordinary his rise from the second level of Qi Refining is 32.
• Remains below Shangguan Wuqing and Dugu Liuli in cultivation despite outranking them socially 36 44.
• No combat technique or direct fight involving Su Yu is demonstrated in the supplied chapters.

Cultivation Arts

• Ten Thousand Blood Pagoda Art: Receives its cultivation scroll from Liu Ziyan as an alternative to the Yin-Yang Evil Demon Art. Liu Ziyan describes its rank as only slightly inferior; Su Yu’s mastery is not documented 24.
• Yin-Yang Evil Demon Art: Repeatedly seeks access to it but is not shown receiving or practicing it. Liu Ziyan offers to teach her once she finds a suitable Dao companion 24.
• Learns from Lin Mo that the art binds a female practitioner to her first partner’s yang energy and causes backlash if she subsequently dual-cultivates with someone else 34.

Covert Communication and Manipulation

• Sends a secret note through a flying spirit beast, checking her surroundings before and after the exchange 21.
• Uses apparent friendliness and promises of secrecy to question Lin Mo about his cultivation and relationship with Shangguan Wuqing 34 43.
• Leverages her Saintess status to persuade Dugu Liuli to arrest him, while avoiding personal responsibility for the outcome 44.
• Changes tactics when prosecution fails, offering Lin Mo a covert escape from the sect in an attempt to win him over 50.

Equipment / Weapons / Items

• Ten Thousand Blood Pagoda Art scroll — An ancient, blood-colored parchment scroll given to her by Liu Ziyan 24.

Relationships

• Liu Ziyan — Master and sect leader. Protects Su Yu from the drawbacks of the Yin-Yang Evil Demon Art by withholding it and supplying another method; Su Yu secretly seeks the very art her master refuses her 24 50.
• Lin Mo — Initially a familiar servant whom she assists by delivering his report. After he witnesses her covert communication, she questions him, arranges his arrest, and eventually attempts to recruit him. She also privately finds him attractive 9 21 43 44 50.
• Hong Yue — Grand elder investigating her as the suspected sect mole. Uses Lin Mo and his access to the Yin-Yang Evil Demon Art as bait 33 42.
• Dugu Liuli — White Tiger Squad captain pressured into arresting Lin Mo. Later refuses to prosecute him, frustrating Su Yu’s plan 44 50.
• Shangguan Wuqing — Lin Mo’s protector and dual-cultivation partner. Su Yu investigates their relationship; Lin Mo suspects her involvement in Wuqing’s removal from the sect, but that involvement is not confirmed 43 48 49.

Story Role / Major Arcs

Delivering Lin Mo’s Report

Su Yu carries Lin Mo’s misconduct report against Maidservant Department steward Lü Mingtong to Liu Ziyan. After reading it, Liu Ziyan orders her to deliver it to the Enforcement Hall for investigation 9.

Secret Correspondence and the Cultivation Art

Lin Mo accidentally witnesses Su Yu giving a note to a flying spirit beast. She follows him far enough to identify him but cannot determine whether he saw the exchange, leaving both wary of the other 21.

After reaching Foundation Establishment Perfection, Su Yu asks for the Yin-Yang Evil Demon Art and receives the Ten Thousand Blood Pagoda Art instead. Her repeated requests help arouse Hong Yue’s suspicion that she is the sect’s mole 23 24 33.

Hong Yue recruits Lin Mo to draw her out. He reveals that he practices the coveted art, provoking Su Yu’s anger, then explains its drawback. She leaves without obtaining it 33 34.

Attempts to Use the Enforcement Hall

When Lin Mo returns after a prolonged absence, Su Yu questions him about his injuries and Shangguan Wuqing. He gives her a partly fabricated account that conceals Hong Yue’s involvement 43.

Su Yu then urges Dugu Liuli to arrest him over Enforcement Hall disciple Zhu Fan’s death, explicitly revealing that Liu Ziyan is away so the captain can approach Purple Heaven Palace. She declines to take charge of his punishment herself 44.

Lin Mo later suspects Su Yu of engineering further arrests and separating him from Shangguan Wuqing. These suspicions remain unproven. Her confirmed attempt to secure his prosecution fails when Dugu Liuli becomes unwilling to act against him 48 49 50.

Attempted Recruitment

Fearing exposure and recognizing that Dugu Liuli will not prosecute Lin Mo, Su Yu considers exploiting his century of mistreatment as a servant. She visits his hut at night, expresses sympathy for his circumstances, and offers to help him leave the First Saint Sect without anyone discovering it. Lin Mo recognizes the possible recruitment attempt and remains suspicious; no agreement is reached in the supplied passage 50.
