Background / History

Shui Wuxin was Skywater Academy’s greatest genius twenty years before the events surrounding Su Yu’s enrollment. Like Xue Wu, she possessed innate level-eight Soul Power and once struggled with doubts about her own potential before being sternly corrected by her teacher. That experience later shapes how she mentors Xue Wu. 99 167

She participated in the Five Element Academy exchanges during her student years and remained familiar with the event’s location and traditions. 139

As Skywater’s traditional all-female model became increasingly unsustainable, Shui Wuxin supported reform. She believed the academy needed to accept talented Soul Masters regardless of gender or elemental affinity, warning that its old rules could eventually lead to its decline. 59

Personality

Shui Wuxin is an ambitious, protective teacher who places her students’ safety and advancement above courtesy or political pressure. She refuses Flender’s demand to surrender Su Yu, declaring that abandoning her students would be unacceptable, and personally confronts both Flender and Zhao Wuji. 79 83

She is highly invested in Skywater Academy’s future. Su Yu’s recruitment, the team’s Martial Soul Fusion Skill, and the students’ rapid advancement all strengthen her belief that Skywater can contend for the championship and rise in status. 59 102 107

Her mentoring can be stern and physical: she ignores Shui Yue’er’s careless behavior, threatens to punish students who waste academy resources, and knocks Su Yu out after he repeatedly calls her “Old Woman.” 71 99 143 However, she also offers direct reassurance when Xue Wu feels inferior and treats Su Yu, Wang Qiu’er, and Xiao Wu warmly upon their return. 167 224

She is notably concerned with beauty, accepting an Immortal Herb only after learning that it can improve her skin. 111

Story Role / Major Arcs

Recruiting Su Yu

Shui Wuxin meets Su Yu in Heaven Dou City and invites him to join Skywater Academy despite his gender and fire attribute. She considers his talent worth making an exception and sees his enrollment as part of the academy’s needed reforms. 59

She completes Su Yu’s enrollment alongside Wang Qiu’er and Xiao Wu, providing uniforms and arranging their accommodations. 70

Building the Skywater Competition Team

As the team’s teacher, Shui Wuxin gathers Su Yu, Shui Bing’er, Shui Yue’er, Xiao Wu, Wang Qiu’er, and Xue Wu to address the shortage of a seventh tournament member. She proposes traveling across the continent to recruit another genius. 71

She later helps oversee Zhu Zhuqing’s addition to the team and repeatedly encourages Su Yu and Wang Qiu’er to develop a Martial Soul Fusion Skill for the coming competition. 95 97

Defense Against Shrek Academy

When Flender demands that Su Yu resolve the condition inflicted on Dai Mubai and Ma Hongjun, Shui Wuxin confronts him with ice attacks and refuses to make her student responsible for Shrek’s weaker members. 79

Flender and Zhao Wuji later attack her to seize Su Yu. Shui Wuxin battles them with Ice Shatter, freezing techniques, and defensive ice walls until Scarlet King intervenes. 83

Cultivation Support and Tournament Ambitions

Shui Wuxin makes Skywater Academy’s resources available to the team, expecting them to capitalize on their opportunities. After absorbing the Ice Muscle Jade Bone Flower, she recovers from old injuries and rises from level 77 to level 80. 99 117

The successful cultivation of Su Yu and Wang Qiu’er’s Fate Strangulation Martial Soul Fusion Skill greatly raises her hopes that Skywater can challenge Spirit Hall’s dominance. 102

During the Five Element Academy exchanges, she leads the team and dismisses attempts by Hu Yanliang to recruit Su Yu and Wang Qiu’er into the Elephant Armor Sect. 139 142

Later Mentorship

After Su Yu, Wang Qiu’er, and Xiao Wu return following years away, Shui Wuxin welcomes them home but reproaches Su Yu for failing to send letters. 224

As a coming continental conflict approaches, Su Yu instructs her to notify Skywater’s dean and prepare the academy for war. She later asks Su Yu to help train the new competition team. 225 226
