Appearance

Yuan Du Zi is an ageless, flawless-looking woman who commonly wears black clothing and a black gauze blindfold over her eyes. She can perceive her surroundings without opening them. 312 434

• Long black hair and pale, jade-like skin 415 568
• Usually dressed in a black long dress or black martial attire 366 434
• A black gauze eye covering despite her ability to see 312
• Her Dharma Body is the Black Seal Kunpeng. 415

Personality

Yuan Du Zi generally presents herself as calm, gentle, and unhurried, even when facing hostile Grandmasters or managing a collapsing political situation. She values results over explanations, telling confused disciples not to dwell on the methods used as long as the desired outcome is achieved. 368

Beneath that composure, she is decisive and often ruthless. She silently eliminates threats she has identified, prioritizes the Xuanmiao Sect's core members over its outer layers, and is willing to pursue dangerous cooperation with Tide to surpass her limits. 366 407 433

Her usual detachment falters around Ansha Lu, a poisoned woman who resembles someone from her past. Yuan Du Zi's determination to save Ansha Lu becomes both an emotional burden and a major weakness exploited by Great Yue. 474 476 501

Yuan Du Zi is recognized as the strongest of Xuanmiao Sect's three chief disciples and later stands among the world's foremost Grandmasters. 312 568

• Defeated or drove back the Wu Army's invading force at Xuanmiao Sect, killing Dinyan Buddha Lord and several high-ranking enemies. 368
• Defeated Muto by a narrow margin in their confrontation at sea, though she concealed the injuries he inflicted. 417
• Blocked Muto's attack in the Great Yue imperial palace and protected Emperor Dingyuan. 562
• Can suppress ordinary Grandmasters so completely that they are unable to exert their strength. 568

Her true-form name is Black Seal, while her manifested Dharma Body is called the Black Seal Kunpeng. 415

• Activates it directly against Muto's Thousand-Armed Tathagata Dharma Body. 415

• The Black Seal Dharma Body was later used as biological source material for the Star Warrior cultivation subjects, including the Black King. 640

Sealing and Suppression

Yuan Du Zi can use overwhelmingly refined force to seal opponents, locations, and abilities.

• Sealed Wei He within a sea cave; even his full-force strikes, nearing 5.5 million jin, could not move the barrier. 565
• Restrained Li Rong effortlessly, preventing the Grandmaster from using any of her power. 568
• Her lineage's Thousand Mountains Ten Thousand Locks Art is built around suppression and sealing effects, which she has passed down through her disciples. 320

• She selects Wei He for the Mountain Lock lineage and reveals the reality of the True Realm to him. 318
• She assigns Yao Wan to teach Wei He the Thousand Mountains Ten Thousand Locks Art and guide his super-sense development. 319
• She gives Wei He double newcomer resources, protection, a superior Heavy Moon Sky Wolf Array, and later a customized life-saving Star Array. 350 402 410

History

Yuan Du Zi began as the chief disciple of Xuanmiao Sect's Mountain Lock lineage. She was regarded as the strongest among the three chief disciples, and her lectures were the most popular in the sect. By the time Wei He entered Xuanmiao Sect, she was effectively the person wielding real authority within it. 312 314

She noticed Wei He's potential early. She supplied him with high-concentration Sea Kelp Paste, arranged protection after he killed members of the Incense Gathering Cult and Chaos God Cult, and personally accepted him into the Mountain Lock lineage. 314 318

When her master returned wounded and entered seclusion, Yuan Du Zi assumed responsibility for the Mountain Lock lineage, a role she had already performed in practice for more than a century. She later exposed the fact that Xiao Ling had been replaced by a Wu State impostor and killed him before the infiltrators could act. Her confrontation with Yuan Zhen Zi revealed both her Grandmaster cultivation and the long-standing bitterness between them. 329 366

Following the Wu State's assault on Xuanmiao Sect, Yuan Du Zi repelled the invasion and kept the details of her victory sealed from most of the sect. When Haizhou fell, she led Xuanmiao Sect's relocation overseas and continued to deter Great Yue through her personal strength. 368 389

As Great Yue's True Blood system increasingly outpaced True Energy cultivation, Yuan Du Zi opened negotiations with Tide in search of a way beyond her Grandmaster limits. Her attempt to save Ansha Lu—whose face evoked a person from her past—became central to this pursuit. She eventually sought to sever Ansha Lu's hold on her and break into a higher realm. 433 474 530

After her breakthrough, Yuan Du Zi intervened directly in Great Yue's imperial affairs, confronting Muto and shielding Emperor Dingyuan. The later collapse of True Qi and emergence of the Void Mist separated her from Wei He for a time; he eventually searched the Void Sea for traces of her. 563 621

In the distant future, Yuan Du Zi and Li Rong survive into a psionic civilization, joining the Eastern Extreme Alliance. She becomes an investigator, cultivates psionic energy, and continues pursuing higher martial realms while combating Star Abyss threats. 780 806 835
