Background / History

Wu Siduo first appears in Suotuo City as a girl who came from another point in time. When Dai Mubai and Ma Hongjun confront her over the newly established Shrek Academy, she responds with open coldness and disgust rather than backing down 1.

She decisively defeats Dai Mubai and Ma Hongjun. Her Nether Civet possession and four purple soul rings shock Dai Mubai, while her speed leaves him unable to retaliate; she then incapacitates Ma Hongjun with Nether Shadow Clone 2. Dai Mubai subsequently suspects a connection between her and the Star Luo Empire's Zhu Family because of her Nether Civet martial soul 3.

Wu Siduo later leads Ning Rongrong and Zhu Zhuqing to the academy dormitory, confidently telling the incoming students that Shrek can turn them into monsters in the eyes of the outside world 15. She is subsequently revealed to be an internal student of Shrek Academy rather than a newly admitted recruit. During class introductions, she identifies herself as a rank forty-four agility-attack battle soul master with the twin martial souls Evil Eye White Tiger and Nether Civet 17 18.

In the academy's virtual practical assessment, Wu Siduo leads a team with Ning Rongrong, Dai Yun'er, and Zhu Zhuqing. Her team swiftly eliminates Luo Ziyan's and Zhang Yangzi's groups before facing Tang Wulin's team 31. Against Tang Wulin, she uses her self-martial soul fusion skill to become the Nether White Tiger, but the form's steep expenditure of soul power and Tang Wulin's amplification from Ye Zhi ultimately lead to her elimination 33 34.

When challenged by Xu Xiaoyan's group, Wu Siduo proposes a two-against-three match, explaining that she and Dai Yun'er are both four-ring Soul Ancestors. She later finds that Xu Xiaoyan's control ability can directly restrain her tiger form 62 64.

Wu Siduo later states that she comes from the ordinary Wu Family, though Ning Rongrong finds it difficult to reconcile such a background with Wu Siduo's exceptional cultivation and resources 89. During the academy competition, she has advanced to rank fifty-seven and faces Tang Wulin in a highly watched match. Despite deploying Battle Armor and her strengthened Hell White Tiger fusion, she is defeated by Tang Wulin's Golden Dragon bloodline abilities 222 224 226 227.

Appearance

Wu Siduo is consistently described as cold-faced and composed. During Nether Civet possession, black cat ears emerge atop her head and she manifests sharp claws 2.

• Maintains an expressionless, aloof demeanor in and out of combat 2 31.
• Gains fluffy black cat ears through Nether Civet possession 2.
• Uses clawed hands while fighting 2 31.
• Her face becomes pale and her legs weaken after exhausting the Nether White Tiger form 34.
• Her silver-white Battle Armor bears patterns of the Hell Spirit Cat and White Tiger martial souls 226.

Personality

Wu Siduo is terse, controlled, and confident in her own judgment. She rarely responds to praise or panic, instead giving brief instructions and continuing toward the objective 31 32.

Despite her intimidating strength, she explicitly states that she does not look down on fellow Shrek students. Her decision to arrange a two-against-three challenge is based on the advantage held by the two four-ring representatives, not contempt for their opponents 62.

She is willing to instruct classmates who seek self-improvement. When Zhu Zhuqing and Dai Yun'er struggle to apply their soul skills more effectively, Wu Siduo demonstrates how Hell Stab can be adapted for movement and retreat rather than used only offensively 61.

Following her team's loss in the practical assessment, Wu Siduo does not blame Ning Rongrong or Zhu Zhuqing for their defeat, telling them not to worry despite their guilt 35.

She is pragmatic about ambition. When Ning Rongrong speaks of becoming a god, Wu Siduo cautions that godhood requires both strength and luck 159.

Abilities & Skills

Twin Martial Souls

Wu Siduo possesses the rare combination of the Evil Eye White Tiger and Nether Civet, martial souls whose pairing deeply shocks Zhu Zhuqing and the class 18.

• Identified as a rank forty-four agility-attack battle soul master during her class introduction 18.
• Possessed four purple soul rings at the beginning of the story 2 32.
• Reaches rank fifty-seven and displays five soul rings—one purple and four black—during her match against Tang Wulin 222 224.
• Her martial-soul combination resembles the inherited pair associated with Star Luo’s Dai and Zhu families, prompting Dai Mubai to question her connection to the Zhu family 3.
• Her combination of White Tiger and Nether Civet is exceptionally rare even by the standards of the Star Luo Empire's Dai and Zhu families 226.

Nether Civet Possession

Her Nether Civet, also referred to as the Hell Spirit Cat, emphasizes extreme speed, claw attacks, and rapid close-range pressure.

• Overwhelmed Dai Mubai despite his White Tiger Barrier, leaving him covered in wounds 2.
• Uses dense, high-speed claw barrages that prevent opponents from launching their own skills 2.
• Eliminated Luo Ziyan’s entire virtual team before Ning Rongrong could provide support 31.
• Its offensive power is sufficient to tear apart Tang Wulin's Blue Silver Emperor vines through direct claw strikes 224.

Hell Stab

Hell Stab can be used as a movement technique rather than solely as an attack.

• Lets Wu Siduo abruptly alter direction in midair while moving at high speed 61.
• Can be used to disengage or retreat after attacking 61.
• Previously used to launch an explosive close-range attack against Dai Mubai under the name Nether Thrust 2.

Nether Hundred Claws

Wu Siduo's second soul skill unleashes a dense barrage of high-speed claw strikes.

• Filled Dai Mubai's field of vision with claw attacks and broke through his defenses despite the protection of White Tiger Barrier 2.
• Left Dai Mubai covered in numerous bloody wounds while preventing him from effectively retaliating 2.

Nether Slash

Wu Siduo's third soul skill condenses black soul power into a massive blade of light.

• Forms a black blade more than two meters long 2.
• Severely wounds Dai Mubai across the chest before he can use his third soul skill 2.

Nether Shadow Clone

Wu Siduo's fourth soul skill splits her into multiple identical copies.

• Initially divides her figure from one into four 2.
• Uses the clones to overwhelm and defeat Ma Hongjun in a coordinated barrage 2.
• At five rings, can create seven clones with genuine offensive power, allowing her to attack an opponent from multiple directions simultaneously 224.

Nether Prison Lock Claw

Wu Siduo's fifth soul skill creates black chains from her claws to imprison an opponent.

• Uses seven chains in conjunction with Nether Shadow Clone to seal Tang Wulin's avenues of escape 224.
• The chains restrict movement and interfere with the target's circulation of soul power 224.
• Tang Wulin's Golden Dragon Shakes the Earth can destroy the chains and disperse her clones through overwhelming force 224.

Self-Martial Soul Fusion Skill: Hell White Tiger

Wu Siduo can fuse her own twin martial souls into the Hell White Tiger, also rendered as the Nether White Tiger, a massive tiger form with greatly enhanced combat power 33 34 226.

• Transforms into a tiger approximately five to six meters long 34.
• Its claws can clash directly with Tang Wulin's Golden Dragon Claw, though its strength remains inferior in a head-on contest 34.
• The form consumes substantial soul power and spiritual power, making it difficult to maintain for long 34.
• She is left pale, unsteady, and nearly out of soul power when the transformation collapses 34.
• Xu Xiaoyan's Star Wheel Chain is capable of hard-controlling the tiger form 64.
• At the five-ring stage, the form is over five meters long, possesses black-and-white fur, scaled foreclaws, and an estimated martial-soul compatibility of at least eighty percent 226.
• In this form, her speed is twice that of her Hell Spirit Cat possession, allowing her to evade opponents through extreme agility and an illusory movement method 226 227.
• She can combine the fusion with Battle Armor, but its consumption remains severe enough that extended combat rapidly depletes her soul power 226 227.
• During her final exchange with Tang Wulin, she ignites strange flames over the Hell White Tiger to increase its power before being overcome by his Golden Dragon Berserk Domain 227.

Battle Armor

Wu Siduo possesses silver-white Battle Armor that augments her combat capabilities.

• The armor is engraved with White Tiger and Hell Spirit Cat patterns and can be summoned before she activates the Hell White Tiger fusion 226.
• She uses both Battle Armor and her self-martial soul fusion skill in her tournament battle against Tang Wulin 226 227.

Three-Person Martial Soul Fusion: Three-Eyed Underworld Tiger

Wu Siduo participates in a three-person fusion with Zhu Zhuqing and Dai Yun'er, creating the Three-Eyed Underworld Tiger 84 85.

• The fusion combines Wu Siduo's Evil Eye White Tiger, Dai Yun'er's Spirit Eye, and Zhu Zhuqing's Hell Spirit Cat martial souls 84 85.
• The resulting tiger possesses exceptional speed despite its size and can leave deep claw marks on a fused golden dragon opponent 85.
• The fusion leaves all three participants pale, sweating, and heavily depleted in soul power and stamina 85.
• Spirit Resonance Water improves the trio's compatibility, allowing their fusion to become more harmonious, stronger, and longer-lasting in subsequent tests 86.
