Background / History

Jiang Zichun was a senior student of Xiaoxiang Academy in Liyao City, Great Chu. The academy accepted awakened adult women, and Jiang initially ranked around ninth or tenth in its monthly competition despite having strong grades. Unable to rapidly improve her cultivation or swordsmanship, she searched for an inexpensive restraining divine ability to complement her Fragrant Sword technique. 3

On the eve of the competition, she discovered and purchased Mathematics: Chicken and Rabbit in the Same Cage for 100 Qi Luck Points. She quickly recognized that forcing an opponent to solve a problem inside an illusion could create a decisive opening in real combat. 3

Her use of the ability transformed the monthly competition. She defeated Zhang Yurou and several other opponents, rising through six consecutive victories to second place. She ultimately conceded to the reigning first-place An Youyi, whose accelerated thinking and Heavenly Origin Technique let her escape the illusion unusually quickly. 6 7 8

Knowing that the ability’s conspicuous name made secrecy impossible, Jiang openly told the other top-ranked students how to acquire it. She then organized them to exploit their short-lived advantage by challenging nearby academies for Earth Luck Points. At An Youyi’s suggestion, she also reported the divine ability to Xiaoxiang Academy, receiving recognition from Dean Wu. 8 17

Jiang became one of “Master Anonymous”’s earliest and most devoted followers, repeatedly requesting expansions to the Chicken and Rabbit in the Same Cage question bank. Her enthusiasm for the supplement and later mathematical works led her from a frustrated arithmetic student to a dedicated mathematics teacher and researcher. 22 24 116

Appearance

Jiang Zichun is depicted in practical academy attire during combat and more refined clothing during her mathematical work.

• Wore a moon-white training uniform while observing the Xiaoxiang Academy tournament. 6
• Wore a purple skirt while discussing her tangent-discovery with An Youyi. 167

Personality

Initially described as gentle and amiable, Jiang can become irritable when frustrated by competition or difficult studies. Her anxiety about losing her top-ten standing pushed her to search relentlessly for a practical advantage before the monthly tournament. 3 24

She is strategic rather than naïvely generous. She disclosed her new divine ability because others could soon identify it anyway, choosing to gain goodwill and organize a profitable academy-challenge campaign instead. 8

Jiang is highly persistent in mathematics. Even after teaching left her exhausted and discouraged, she continued studying geometry, discussing problems with fellow scholars, and investigating the principles behind her tangent method. 134 136 167

She also holds firm convictions about women’s rights. Jiang believes legal changes alone cannot eliminate entrenched attitudes toward women, leading her to build the Xiaoxiang Society and later join the Equality Society. 241 242 243

Abilities & Skills

Mathematics: Chicken and Rabbit in the Same Cage

An illusion-based spirit-stabilizing divine ability purchased by Jiang from the Divine Ability Treasury. It forces a target to solve a mathematical problem, disrupting their awareness in the real world. 3

• Must strike the connection between a target’s body and soul; for humans, this means the head. 3
• At Jiang’s initial 3.8-inch Talent Qi cultivation, its effective range was 3.8 meters. 3
• The owner can select a problem range, randomize questions, and adjust difficulty. 3
• In the monthly competition, Jiang chained the illusion’s opening with Feint to the East, Attack in the West to defeat Zhang Yurou. 6
• Its effect weakens against opponents who can solve problems faster; An Youyi used Human Luck Points and the Heavenly Origin Technique to minimize her distraction. 8
• A later supplement expanded its question bank, increased its classifications from three to five levels, and made answer-memorization far less practical. 24
• Its self-questioning feature can evaluate owner-created problems, identify unsolvable questions, and return multiple valid answers where applicable. 25

Question Generation

As a Calculation Node, Jiang can generate and publicly share mathematical questions through the upgraded system. 71

• Receives Luck Points based on a question’s difficulty and the time others spend solving it. 71
• Duplicate questions do not generate the same value; 136 of her first 240 uploaded questions were duplicates. 71
• She notified Yu Rou and An Youyi of the feature rather than keeping it to herself. 71

Fragrant Sword Technique

Jiang’s primary martial foundation is the Fragrant Sword technique, a fast and decisive close-combat style. 3 6

• Used alongside a sword summoned through the Mohist Sword Formation divine ability. 6
• Her swordsmanship alone was insufficient against An Youyi’s overwhelming hammer strength, forcing her to concede after repeated heavy impacts numbed her hands. 8

Feint to the East, Attack in the West

A Military Strategist divine ability used to create a deceptive dual-sword attack. 6

• Produced two identical swords with different apparent targets. 6
• Combined with Chicken and Rabbit in the Same Cage to exploit Zhang Yurou’s momentary loss of focus. 6

Mathematical Research

Jiang developed from a divine-ability user into a major mathematical scholar.

• Learned arithmetic methods from the Ten Books on Mathematical Art and persisted despite finding the coursework mentally overwhelming. 24
• Studied geometry through Elements, including proof by contradiction, geometric axioms, and step-by-step derivations of area formulas. 135 136
• Derived a method for finding tangent lines to polynomial curves; other scholars verified it across quadratic, cubic, quartic, negative-exponent, and fractional-exponent cases. 166 167
• Is credited with creating Calculus, Differential Geometry, and Mathematical Analysis, while contributing to numerous other disciplines developed through Xiaoxiang Academy. 242
• Continued attempting to prove Fermat’s Last Theorem, a problem posed in Mathematics and left unresolved for decades. 242

Story Role / Major Arcs

• Xiaoxiang Academy Monthly Competition — Purchases Chicken and Rabbit in the Same Cage, uses it to rise from a precarious top-ten position to second place, and loses the final to An Youyi. 3 6 7 8

• Mathematics Teacher and Researcher — Accepts a teaching position in Xiaoxiang Academy’s Mathematics Department, studies geometry, and discovers a general tangent-calculation method. 116 134 166 167
• Xiaoxiang Society — Helps establish a women’s association centered on Xiaoxiang Academy and dedicated to advancing women’s rights. 241
• Equality Society Alliance — Chooses to join Jing Zhi’s Equality Society, despite the danger, to pursue deeper social change for women. 242 243
• Recognition of Master Anonymous — Learns that her idol, Master Anonymous, was Lu Mingyuan after the appearance of Great Grandmaster-level purple qi. 266

• An Youyi — Best friend, former tournament rival, and fellow Xiaoxiang Society member. An Youyi exposed the countermeasure to Jiang’s illusion ability, supported her teaching ambitions, and encouraged her mathematical discovery. 7 8 116 167
• Lu Mingyuan / “Master Anonymous” — Creator of the divine ability that launched Jiang’s mathematical path. She became his devoted admirer before eventually learning his identity. They later discussed mathematics through scholarly groups. 3 22 166 266
• Zhang Yurou — Xiaoxiang Academy competitor defeated by Jiang during the monthly tournament; Jiang later included her in the plan to challenge outside academies. 6 8
• Gu Qiuhui — Xiaoxiang Academy master who discussed Jiang’s appointment to the Mathematics Department. 116
• Xia Tian — Mathematical peer who verified Jiang’s tangent method and praised the significance of her work. 167
• Ling Ji — Husband. Initially worried about the risks of her equality activism, but ultimately supported her decision after learning of her imminent Grandmaster advancement. They have a son and a daughter. 243
