Appearance

Wu Dayi can conceal his cultivation so completely that he appears indistinguishable from an ordinary mortal. In battle, he is described as gentle, refined, and elegant, even while confronting a large force alone. 236 387

• Usually fights with the flute Shadow Moon. 145 197
• His flute’s lingering sound can be heard even while he rides it through the air. 236
• Blood refinement created an unusually intimate link between him and his treasure, which moves according to his thoughts. 145

Personality

Wu Dayi is dependable, cautious, and protective of his martial brothers. When Zhang Xiaofan and others failed to return from beneath Death Spirit Abyss, he brought supplies down himself out of concern. During crises, he takes practical action, whether distracting hostile Yin Spirits during exploration or organizing the defense of Two Mountains when Luo Yunji’s Rain Technique leaves with him. 131 204 411

He is also modest about his own progress. Although his mental attribute allows him to influence others without spiritual power, he initially considered his control insufficient. He later struggles with the intermediate footwork and openly admits that he has not yet mastered the Dragon-Slaying Art. 179 945

His calmness can give way to embarrassment in personal matters. He repeatedly insists that his relationship with Miss Zhao is limited to discussions of music theory, while He Dazhi relentlessly teases him about it. 590

Abilities & Skills

Spirit Attribute and Mental Arts

Wu Dayi possesses a spirit attribute oriented toward the mind, particularly mental interference and control rather than the five elements. 102 179

• Can directly influence and control people without relying on spiritual power. 179
• Produces sensory disturbances that can disrupt sight, hearing, touch, and spatial perception; he himself remains unaffected by these distortions. 232
• Can use his attribute to create illusions for cultivation breakthroughs, though Tian Buyi worries about the risks of this method. 760
• His control was initially incomplete, and uncontrolled effects once forced his fellow disciples to isolate him until he could regain command. 179 232

Shadow Moon

Shadow Moon is Wu Dayi’s blood-refined flute and primary magic treasure. It was forged from a spirit-attribute stone staff, strengthened with a silver Cheng Liquid gemstone, and fused with Wu Dayi’s blood. 102 145

• Creates an instinctive mind-to-treasure connection; Wu Dayi can direct it with a thought. 145
• Its completion briefly disrupted the onlookers’ five senses and caused them to lose awareness of time. 145
• Blurs enemies’ senses, buying openings for allies to escape or counterattack; it briefly disrupted Old Ancestor Fengyue despite the latter’s far greater cultivation. 197
• Can fly beneath Wu Dayi’s feet as a transport treasure. 236
• Its sound and physical sweep can freeze opponents in place, after which Wu Dayi can incapacitate them by striking their vital points. 387
• Contains a secretly engraved formation based on the evil Soul-Hooking Umbrella, enabling it to devour living beings and souls. 386 387
• Using its soul-devouring power at full force caused extreme backlash, leaving blood flowing from Wu Dayi’s seven orifices after his attack on Yuyangzi. 387

Dragon-Slaying Art

Wu Dayi is uniquely able to perceive the text on the stone slab containing the Dragon-Slaying Art, which appeared blank to He Dazhi. He recited the art for Zhang Xiaofan to identify flaws in his understanding. 131 138

• Studies the art alongside the Taiji Mystic Purity Dao. 138
• Understands its teachings concerning spirit, qi, essence, and the Twelve Evil Dragons. 138
• Had not mastered the art by the time he began struggling with intermediate footwork. 945

Footwork

Wu Dayi practices the group’s movement arts but advances more slowly than Zhang Xiaofan.

• Made early progress with the Twelve Steps while traveling from the Imperial City. 196
• Could execute only seventeen steps of the intermediate footwork, less than halfway through the technique. 945
• Continued training in preparation for the Beast Demon and the approaching Great Calamity. 945 984

Equipment / Items

• Shadow Moon — Blood-refined spirit-attribute flute used for mental interference, sensory disruption, flight, and soul devouring. 145 197 387
• Chronicles of the Illusory World — A storybook Luo Yunji sought out for Wu Dayi because of his special attribute; Tian Buyi permitted Wu Dayi to read it despite forbidding the other disciples from doing so. 175

Story Role / Major Arcs

Acquisition of Shadow Moon

In Black Mountain, Wu Dayi receives a stone staff suited to his mind-oriented spirit attribute after Luo Yunji determines that it is incompatible with his own abilities. The staff and yellow gemstones become the basis for Wu Dayi’s future magic treasure. 102

At Black Stone Cave, he refines the weapon into a flute, fuses his blood into it, and strengthens it with a silver Cheng Liquid gemstone. The completed treasure is named Shadow Moon. 145

Discovery of the Dragon-Slaying Art

Wu Dayi discovers that he alone can read the Dragon-Slaying Art’s inscription on a stone slab beneath Death Spirit Abyss. He later recites its text to Zhang Xiaofan, allowing the two to compare the art with the Taiji Mystic Purity Dao. 131 138

Imperial City and Demon Sect Pursuit

Wu Dayi realizes that his mental attribute can control people directly without spiritual power and begins testing the ability in the Imperial City. 179

When Old Ancestor Fengyue attacks He Dazhi, Wu Dayi uses Shadow Moon to blur the elder’s senses for a single crucial instant, enabling He Dazhi to escape through the Twelve Steps. 197

Battle Against the Demon Sect

During the Demon Sect conflict, Wu Dayi reveals the soul-devouring formation hidden within Shadow Moon. He advances through the enemy ranks, gathers more than a hundred souls, breaks through to the Upper Purity Realm, and brings Yuyangzi down with one strike. 386 387

The victory nearly destroys him. His use of the Blood Refining Technique and the ghostly phenomena surrounding him draw suspicion from the righteous-path leaders, though Tian Buyi defends his actions as having saved allied disciples. 387 392 398

Leadership at Two Mountains

After relocating to Two Mountains, Wu Dayi takes on administrative and defensive responsibilities. He helps manage Sanfu Town, oversees soldiers, and orders them to secure the mountain passes when Luo Yunji’s absence removes the protection of the Rain Technique. 410 411

His experience and manner lead visiting Azure Cloud disciples to recognize his ability to handle major affairs. 422

Taking Disciples

Wu Dayi accepts Zhong Ming as a disciple without first informing Tian Buyi, then kneels to admit his mistake. Tian Buyi ultimately recognizes Zhong Ming’s spirit attribute and formally accepts him into Big Bamboo Peak. 472

He later serves as Duan Ming’s master, testing the boy’s footwork, directing his training, and encouraging him after Wu Dayi’s return from seclusion. 954 1056

Relationships

• Tian Buyi — Master. Wu Dayi trusts Tian Buyi’s judgment, admits wrongdoing before him when he takes Zhong Ming as a disciple without permission, and receives Tian Buyi’s defense after using Shadow Moon’s forbidden formation. 392 472
• He Dazhi — Junior martial brother and close collaborator. He Dazhi assists in refining Wu Dayi’s flute, worries intensely when Wu Dayi enters battle with Shadow Moon’s soul-devouring formation, and frequently teases him about Miss Zhao. 102 145 387 590
• Zhang Xiaofan — Junior martial brother. Zhang Xiaofan helps Wu Dayi realize that his mental attribute can be used directly for interrogation and cultivation, and later urges him not to abandon his footwork training. 179 945

• Duan Ming — Disciple. Wu Dayi tests his footwork, regulates his training, and directs him to choose a companion from Lizi. 954 1056
• Zhong Ming — Disciple. Zhong Ming initially addresses Wu Dayi as master before Tian Buyi formally approves his admission to Big Bamboo Peak. 472
• Miss Zhao — Acquaintance and possible romantic interest. Wu Dayi states that they only discuss music theory and that she sells art rather than herself. 590
