Background

Wu Su was regarded as the greatest Sword Dao prodigy in the history of the Wu Family Sword Domain. She was betrayed by her closest confidante, who destroyed her body and imprisoned her Nascent Soul inside the Soul Locking Jade. Her betrayer later became a Nascent Soul cultivator in the Sword Domain and married Wu Su's brother, Wu Tianyun. 100 104

She remained sealed for approximately a century. A previous person who received her Otherworldly Sword Art: Upper Scroll while seeking Soul Nurturing Wood for her disappeared without returning. 100

When Qin Wang discovered the Soul Locking Jade, Wu Su initially considered him too weak to aid her recovery. He nevertheless promised to search for Soul Nurturing Wood, while she taught him the Upper Scroll of the Otherworldly Sword Art in return. 100

Appearance

Wu Su's appearance changed with her recovery: she first appeared as a fading soul projection, then later manifested in a solid body formed through the Sword Domain inheritance.

• An illusory, graceful woman with rippling features while sealed in the Soul Locking Jade. 100
• Described as peerlessly beautiful, sacred, and difficult to look upon directly. 100
• Usually appears in flowing white robes, with a cold and noble bearing likened to an immortal maiden. 230
• After regaining a body, she wears white and carries the Ancient Sword at her waist, giving Wu Zhixing the impression of a “White-Clad Sword Immortal.” 369
• Her Innate Sword Body constantly radiates potent Sword Intent and Sword Qi. 368

Personality

Wu Su is composed, proud, and notably restrained even when facing danger. Her determination to restore herself stems not only from survival, but from her need to confront the betrayal and unanswered events surrounding her death. 100 251

She is fiercely independent. Although Qin Wang offered to accompany her back to the Wu Family Sword Domain, she insisted that the matter was hers to resolve and refused to make him bear the burden she carried. 251

Despite her cool demeanor, Wu Su is deeply loyal to those she accepts. She repeatedly guides Qin Wang, worries about the dangers surrounding him, and later credits thoughts of her family, Wu Tianyun, and Qin Wang with helping her resist the Gate of Swordsmanship's promise of eternity. 116 140 368

Story Role / Major Arcs

Soul Locking Jade and Recovery

Wu Su enters the story as a fading Nascent Soul sealed in the Soul Locking Jade. She and Qin Wang form a mutually beneficial pact: she provides Sword Dao instruction, while he searches for materials that can prevent her dissipation. 100

Qin Wang secures the Thousand-Year Soul Nurturing Wood, then spends heavily to obtain the Skyfire Pagoda and later gives her a Soul Stone. These resources restore her divine soul to its peak and allow her to act openly alongside him. 141 195 230

Qin Wang's Guide and Combat Support

Wu Su becomes Qin Wang's principal Sword Dao mentor, providing the Otherworldly Sword Art, Starfall Sword Canon, cultivation advice, and intelligence drawn from her experience. 100 109 116

Once restored, she assists Qin Wang in major confrontations: controlling the Ten Thousand Zhang Blood Crocodile, using the Barbarian God's Left Hand, and testing the combat strength of the Five Ghosts. 231 236 238

Return to the Wu Family Sword Domain

Wu Su leaves Qin Wang to settle the unresolved matter of her death and return to her ancestral Sword Domain. Qin Wang later follows to protect her while she accepts the Ancient Sword's inheritance, despite threats from the Wu Family's internal factions and outside sects. 251 334 335

Her brother Wu Tianyun attempts to atone by opening the Gate of Swordsmanship for her. Inside the gate, Wu Su rejects the offer of eternal dominion over the Way of the Sword, instead using its Sword Qi and Intent to forge an Innate Sword Body and return to the real world. 365 368

Devouring the Sword Domain

Wu Su remains in seclusion to refine the Ancient Sword and complete the inheritance by devouring the Wu Family Sword Domain. She refuses to flee before completing this process despite the approach of Prince En and the Great Yu Immortal Dynasty. 369 372

Upon emerging, she possesses an Innate Sword Body, Peak Spirit Transformation cultivation, and defensive sword qi with Early Integration-level force. She immediately establishes herself as a major combatant by confronting Zhu Jingtian. 382 383

Later Conflicts

Wu Su and Wanyan Meng serve as trusted leaders among Qin Wang's allies during the Tiandu crisis, coordinating responses while Qin Wang faces Huang Tianwudi and Elder Xia. 472

During the Underworld war, she and Wanyan Meng intervene on behalf of the Witch Clan. Their initial assault disrupts the Ten Great Families' forces before they face the family heads directly. 522 523
