Background / History

Wu Siduo comes from a family sharing a bloodline origin with the Star Luo Empire’s royal line. Her family and the imperial branch developed irreconcilable differences ten thousand years earlier. 242

Before entering Shrek Academy, she was already a ranked member of the Young Talent List. After Yu Nanyuan’s victory over Shrek Academy’s representative team at the Tianhai Alliance Grand Competition three years earlier, she regarded him as a future competitor. 142

She entered Shrek as a Four-Ring Soul Elder with Twin Martial Souls and a self-Martial Soul Fusion Skill. Her strength earned her recognition as one of First Grade Class One’s foremost students, and she was later appointed Class Monitor. 140 144 212

Appearance

Wu Siduo is a tall, slender girl with an imposing, distant presence that discourages strangers from approaching. 140

• Brown-red, long, wavy hair. 140
• Fair skin and large eyes. 140
• Usually carries an ice-cold aura. 140
• Her Hell Spirit Cat Avatar gives her black cat ears, ethereal darkness, and sharp vertical pupils. 206 221
• In her dual-martial-soul state, her hair becomes black and white, while her arms gain white fur beneath a dark, illusory radiance. 221

Personality

Wu Siduo is proud, stubborn, and intensely competitive. She values strength, refuses to retreat when confronted by a stronger opponent, and is determined to improve after setbacks. 142 143

Her directness extends to her personal life. After setting her heart on Yu Nanyuan, she openly pursues him despite Gu Yue’s presence and the uncertainty of his feelings. 195 207 232 She is also capable of focus and practicality, setting aside her emotions to discuss battle armor design and the development of her martial souls. 207

Abilities & Skills

Twin Martial Souls

Wu Siduo possesses the Hell Spirit Cat and White Tiger Martial Souls. Their light and darkness attributes can be brought into balance, allowing her to develop techniques unavailable to ordinary Twin Martial Soul users. 140 206

• Can switch between both martial souls and, after her return to Star Luo City, activate them simultaneously. 206
• Requires exceptionally high spiritual power to maintain simultaneous use; her current limit is slightly over one minute. 207
• Possesses Spirit Sea Realm spiritual power and can control multiple bodies at once. 160

Hell Spirit Cat

Her primary agility-based martial soul grants elusive movement, high-speed attacks, and strong close-range claw techniques. 140 159

• Hell Stab — greatly increases speed, attack power, and physical defense while making her body ethereal. 142 159
• Netherworld Hundred Claws — unleashes a field of claw shadows capable of destroying Xie Xie’s six clones. 140
• Netherworld Slash — forms a massive black blade that eliminated Xie Xie in a single strike. 140
• Netherworld Shadow Clone — creates two additional illusory clones; her spiritual power lets her control all three bodies seamlessly. 160
• Hell Stab and Netherworld Shadow Clone grant strong resistance to physical attacks, though cold-based effects can still slow her. 160

White Tiger

Her White Tiger Martial Soul supplies power and light-attribute techniques that complement the Hell Spirit Cat’s darkness and agility. 140 221

• White Tiger King Kong Transformation — strengthens her body and attacks, allowing her to combine White Tiger power with Hell Stab’s speed. 140
• White Tiger Light Wave — a light-attribute attack that can be fused with Netherworld Slash. 221
• White Tiger Annihilation Kill — combines with Netherworld Hundred Claws to create a wide-area destructive attack. 221

Hell White Tiger

Hell White Tiger is Wu Siduo’s self-Martial Soul Fusion Skill, fusing and sublimating the bloodlines of the White Tiger and Hell Spirit Cat. It is the main reason her individual strength surpasses many of her peers. 142 161

• Creates a winged, illusion-shrouded Hell White Tiger with explosive power beyond her normal level. 142 221
• Can resist Wu Rui’s Replication Light and prevent him from duplicating her fusion skill. 221 222
• Its final burst can burn the fusion’s power into black-and-white lightning, shattering defenses and incapacitating an opponent. 222
• Consumes substantial soul power and leaves her severely weakened after a full-power attack. 222
• The fusion’s bloodline nature makes it vulnerable to Yu Nanyuan’s Void Dragon Locking Array. 142

Fused Soul Skills

Wu Siduo can merge individual skills from her two martial souls through techniques inherited by her family. 221

• White Tiger Annihilation Kill + Netherworld Hundred Claws — destroys large-scale restraints such as Wu Rui’s vine cage. 221
• White Tiger Light Wave + Netherworld Slash — creates a black-and-white cutting blade combining equal light and darkness energies; it breaks Mirror Reflection by forcing opposing attributes into conflict. 221
• Her combined state gives her White Tiger explosive power alongside Hell Spirit Cat agility, nearly doubling her speed compared with using the Hell Spirit Cat alone. 221

Relationships

• Yu Nanyuan — Fellow Shrek student, competitor, and the person Wu Siduo pursues romantically. She seeks his Martial Soul Imprint to help harmonize the opposing powers of her martial souls. 143 195 207 253
• Gu Yue — Rival for Yu Nanyuan’s attention; their tension becomes apparent during the Sun Moon Royal Soul Engineer Academy challenge. 195 198
• Tang Wulin — Opponent in the freshman free-for-all; Wu Siduo defeated him through sustained close-range attacks. 140
• Xie Xie — Opponent in the freshman free-for-all; she eliminated him with Hell Stab, Netherworld Hundred Claws, and Netherworld Slash. 140
• Xu Yucheng — Fellow Young Talent List member and classmate; they fought together against Yu Nanyuan and later acted on the same Shrek challenge team. 142 194
• Luo Guixing — Fellow Young Talent List member and classmate; he is among her allies during the challenge against the Sun Moon Royal Soul Engineer Academy. 142 194
• Yuanen Yehui — Fellow Twin Martial Soul user who recognizes the unusual nature of Wu Siduo’s fusion; the two can understand each other’s conflicting personal concerns. 221 232
• Wu Rui — Third-year opponent defeated after Wu Siduo used Hell White Tiger and burned its power in a final attack. 221 222

Story Role / Major Arcs

Shrek Academy Freshman Free-for-All

Wu Siduo enters the freshman selection battle as a feared Four-Ring Soul Elder. She detects Tang Wulin and Xie Xie’s ambush, eliminates Xie Xie almost immediately, and then defeats Tang Wulin through a relentless barrage of claw strikes. 140

She later joins Xu Yucheng in attacking Yu Nanyuan. Yu Nanyuan’s Void Dragon Locking Array restrains her, and even Hell White Tiger cannot escape its chains because the fusion skill meets the array’s bloodline-based suppression condition. 142

Class Leadership and Intergrade Battles

Wu Siduo is appointed Class Monitor of First Grade Class One. 144 During the battle against Second Grade Class One, Yu Nanyuan uses Spatial Cage to reposition her and Xu Yucheng directly before the opposing control-system sisters. 159

Her four-ring technique, Netherworld Shadow Clone, allows her to pressure Zhou Hanyou with three coordinated bodies, though the combined fusion skill of Zhou Hanyou and Zhou Tian’er ultimately eliminates her Hell White Tiger. 160 161

Sun Moon Royal Soul Engineer Academy Challenge

Wu Siduo sends Yu Nanyuan footage of Tang Wulin and Xie Xie’s defeat, then waits in Mingdu to join the response team. 193 194 Yu Nanyuan’s overwhelming victory over the academy’s team deepens her admiration and reinforces her determination to make him her partner. 197

Dual-Martial-Soul Development

After returning to Star Luo City, Wu Siduo obtains stronger soul spirits for both martial souls and reaches a balance that lets her activate them together. 206 She asks Yu Nanyuan to design her Dou Kai and later openly confesses her feelings before kissing him. 207

Wu Rui Match

Chosen for the junior league confrontation, Wu Siduo faces the third-year control-system soul master Wu Rui. 220 221 She counters his battlefield-control tactics with her fused light-and-darkness skills, then uses Hell White Tiger’s final burst to defeat him despite his One-Word Dou Kai. 221 222
