Background / History

Wu Siduo and Lin Xun spent three years as classmates at Xingluo Junior Academy in Star Luo City. Although she was renowned as an untouchable prodigy, Lin Xun treated her differently, regularly speaking with her and indulging her pride. She ultimately trusted him enough to lend him her family’s White Tiger Pill, a rare inheritance intended to strengthen her cultivation foundation. 23

Lin Xun transferred to Donghai Academy without returning the pill or properly saying goodbye, leaving only a terse letter. Wu Siduo’s anger centered less on the lost medicine than on the trust she believed he had discarded. After a month of effort, she arranged her own transfer to Donghai Academy specifically to confront him. 23

As Class One’s leader, she challenged Lin Xun during the Year One Promotion Tournament final. She pushed her self Martial Soul Fusion Skill to its limit but was defeated by Lin Xun’s Icefire Purgatory. While recovering afterward, she learned that her original White Tiger Pill had been flawed; Lin Xun had removed it to prevent damage to her foundation and returned a complete pill in its place. 27 28 29

Wu Siduo later entered Zero Class alongside Zhang Yangzi and Wang Jinxi. Her rivalry with Lin Xun remained active, but their relationship became more familiar and trusting through shared training, battles, and his repeated protection of her. 38 50 56 76

Appearance

Wu Siduo is a tall, delicate-featured girl whose proud bearing reflects her status as a celebrated genius. Her hair is described as reddish-brown or wine-red, worn either in curls or a long ponytail. 23 27 38

• Catlike eyes, often narrowed when she is displeased or suspicious. 23 79
• Long reddish-brown hair flowing down her back during the Promotion Tournament. 27
• A lively appearance contrasted by a stubborn, competitive expression. 38
• Her hair flies loose and dark-red when the Hell Spirit Cat Martial Soul fully erupts. 27

Personality

Wu Siduo is proud, stubborn, and intensely competitive. As a genius praised from childhood, she dislikes yielding to others and reacts strongly when her pride is challenged—particularly by Lin Xun. Her decision to confront the Darkgolden Terrorclaw Bear alone was driven partly by her refusal to look weak in front of him. 23 74

She is also deeply loyal once she has chosen to trust someone. Her grievance against Lin Xun came from his unexplained disappearance after she made an exception for him, not simply from the value of the White Tiger Pill. 23

Despite her forceful exterior, Wu Siduo can become visibly embarrassed by direct teasing and shows a vulnerable fear of thunder. She tries to hide this fear, but seeks Lin Xun’s room during storms and clings to him when thunder becomes overwhelming. 55 56 57 79

Abilities & Skills

Twin Martial Souls

Wu Siduo possesses two top-tier Martial Souls: the Hell Spirit Cat and the White Tiger. Their combination gives her exceptional mobility, close-range offense, and physical force. 23 27 61

• Hell Spirit Cat — Provides extreme speed, stealth-like movement, sharp claw attacks, and rapid changes of direction. 27 60
• White Tiger — Grants powerful close-combat strikes and overwhelming physical force. 60 61
• By the Promotion Tournament final, she possesses three soul rings. 29
• Her twin Martial Souls allow her to combine speed and power without relying on teammates. 27

Hell White Tiger

Wu Siduo’s self Martial Soul Fusion Skill forcibly merges her Hell Spirit Cat and White Tiger powers. The resulting giant feline-tiger fusion is also referred to as the Nether White Tiger during the Promotion Tournament. 27 28

• Can be activated independently; she does not require a compatible fusion partner. 27
• Dramatically increases her speed, strength, explosive power, and overall combat ability. 60
• Generates a powerful battlefield-suppressing aura capable of pinning down nearby combatants. 27
• Can sustain direct clashes against powerful combination techniques, though its soul-power cost is severe. 28
• Prolonged use rapidly exhausts her and can force the fusion form to shrink and collapse. 28

Tactical Leadership

Wu Siduo can take command during dangerous team battles and assign roles quickly under pressure. 60

• Ordered Zero Class into a defensive formation against Yue Guan’s projection. 60
• Directed Tang Wulin to defend, Zhang Yangzi and Wang Jinxi to control, Xie Xie to ambush, and Gu Yue to weaken the enemy’s suppression. 60
• Identifies combat limits directly; after failing to pierce Yue Guan’s armor, she immediately warned the team of its defensive strength. 60

Willpower and Soul Tempering

Wu Siduo has a focused, unusually pure mental state and great tolerance for pain. 59

• Advanced farther than any other participant in the Angelic Light corridor, reaching nearly its halfway point. 59
• Continued forward while enduring soul-tempering pain severe enough to make her sweat heavily, keeping her back straight throughout. 59
• Her determination lets her continue fighting even after her soul power is nearly exhausted. 28

Equipment / Items

• White Tiger Pill — A complete, foundation-strengthening pill returned to her by Lin Xun after the Promotion Tournament; it is intended for absorption after reaching three rings. 29
• White Tiger-compatible soul bone — Obtained after the Darkgolden Terrorclaw Bear’s defeat and accepted from Lin Xun. 76

Relationships

• Lin Xun — Former Xingluo Junior Academy classmate and primary rival. She transferred to Donghai Academy to confront him over the White Tiger Pill and his silent departure; after learning his reason and receiving a complete pill, their hostility softened into teasing familiarity and growing trust. 23 29 38 56
• Zhang Yangzi — Class One and Zero Class teammate. He addresses her as “Sister Duo” and coordinates with her in battle. 27 60
• Wang Jinxi — Class One and Zero Class teammate. His Bone Dragon King Martial Soul combines with Zhang Yangzi’s to form the Dark Hawk Dragon alongside Wu Siduo’s own fusion skill. 27 60
• Gu Yue — Zero Class teammate and a competing presence around Lin Xun. Wu Siduo feels left out or jealous when observing Gu Yue’s interactions with him. 50 82
• Xie Xie — Zero Class teammate who frequently provokes her with jokes and doubts, drawing sharp retorts from her. 39 73 78
