Background & History

Zhang Lingxue became renowned for evolving a carefully raised White Jade Silkworm into the Goddess of Light Butterfly with a Tier 4 Stone of Light. Her published work drew widespread attention to the Chameleon Silkworm and helped establish further butterfly evolution research. At the height of this success, she joined Sacred Mountain Middle School as a teacher and researcher. The school gave her a dedicated research area and a heavily secured institute. 1 23

Her decision to remain at Sacred Mountain Middle School was tied to her grandfather, Zhang Dashan. Rather than pursue a more prominent position immediately, she stayed nearby to care for him as his old Beast Tide injuries and hidden toxins worsened. 57

During the Awakening Ceremony, she supervised the students' Pet Beast Space and Talent awakenings, personally recording their results and explaining the ranking system for Talents. 1

Ye Bai's Master

Zhang Lingxue noticed Ye Bai's aptitude for evolution research after he identified the importance of environmental conditions to Chameleon Silkworm evolution. She formally accepted him as her registered Personal Disciple and gave him access to her research institute, provided he learned its equipment manuals within three days. 23 24

Their collaboration produced or advanced research into the Dark Butterfly, Star Ripple Butterfly, Blood Gu Butterfly, Blood Poison Moth, Positive and Negative Charge Rabbits, Sword Butterflies, and later Thunder Rabbit variants. 25 74 93 176 259 473

Return to the Imperial Capital

After completing her work at Sacred Mountain Middle School, Zhang Lingxue resigned as homeroom teacher and returned to Imperial Capital University and the Imperial Capital Research Institute. She left her Sacred Mountain research institute for Ye Bai's future use. 144 157

At the Imperial Capital Research Institute, she was drawn into a wager surrounding research on Equipment-type Exotic Beasts. Her project aimed to reproduce the Spirit Summoning properties of Sword Butterfly Eggs, but she stalled after identifying ninety-seven percent of their composition. Ye Bai's discovery of Sword Spirit Bugs gave the pair a new direction: improve Sword Butterfly reproduction while developing a Spirit Summoning Potion. 236

The project ultimately proved that Sword Butterflies could reproduce repeatedly rather than laying only one egg in their lifetimes, resolving a world-class research problem and cementing Zhang Lingxue's standing within the institute. 254 259

Appearance

Zhang Lingxue has long black hair, a teardrop mole near the corner of one eye, and full crimson lips. Her appearance changes with her work: she wears lab coats in the institute, formal teaching attire in class, and combat gear during field operations. 18 23 297

• Wears a work badge and carries extensive lesson plans while teaching. 18
• Often wears a white lab coat during experiments. 23
• Uses butterfly-themed hair ornaments, including contracted Sword Butterflies worn as hairpins. 254 297
• Received the translucent white Xin Yue Hu White Fox Hairpin upon inheriting the Heart Mansion. 284

Personality

Zhang Lingxue is exceptionally driven in research and can become so absorbed in an experiment that she forgets to eat. Around unfamiliar people, she tends to be aloof and distant, but she becomes openly supportive of those she trusts. 92

She is demanding as an instructor and does not tolerate students treating training casually. Her strictness is paired with practical concern: she repeatedly emphasizes that Pet Beasts are companions rather than tools, prioritizes her students' safety in competition, and personally protects Ye Bai when danger escalates. 18 22 99 107

Her greatest personal vulnerability is her grandfather. She delayed her own career to remain near him, stubbornly pursuing every possible treatment for his illness because he is her only remaining family. 57 80

Abilities & Skills

Species Stacking

Zhang Lingxue's Talent, Species Stacking, allows her to contract an effectively unlimited number of Pet Beasts within the same species category, provided she has sufficient Mental Power. 64

• Moth-type Pet Beasts share a single Contract Slot with her Gray Poison Moth. 64
• Butterfly-type Pet Beasts share a single Contract Slot with her Goddess of Light Butterfly. 64
• Her contracted Pet Beasts occupied only three slots despite her having already contracted multiple moths and butterflies. 64
• The Talent does not remove Mental Power costs; each additional contract still consumes Mental Power. 64
• The death of a contracted Pet Beast lowers her Mental Power threshold. 64

Pet Beast Evolution Research

Zhang Lingxue is a specialist in Chameleon Silkworm evolution and related butterfly-type Exotic Beasts. Her research combines controlled environments, evolution materials, genetic analysis, and reproducibility experiments. 1 23 74

• Developed the Goddess of Light Butterfly evolution path from a White Jade Silkworm. 1
• Researched the Dark Butterfly and discovered the importance of night-time environmental conditions. 23 24
• Produced Evolution Source Liquid with Ye Bai for the Star Ripple Butterfly experiment. 25
• Guided Blood Gu Butterfly and Blood Poison Moth reproducibility experiments. 74
• Redirected the Negative Charge Rabbit project toward preventing their unstable crystal cores from causing Self-Destruction. 93
• Completed research establishing repeatable Sword Butterfly reproduction. 254 259

Light-Attribute Combat and Healing

Through the Goddess of Light Butterfly and its later True Goddess form, Zhang Lingxue commands powerful Light-attribute techniques for purification, healing, and large-scale combat. 299 353

• Used a powerful light attack to destroy Corpse Puppets emerging from the Hero's Cemetery. 299
• The True Goddess of Light Butterfly's Light-attribute power increases severalfold after gaining a trace of divinity. 299
• Used Holy Light healing to restore the Eternal Songstress's damaged vocal cords. 353
• Is personally immune to Light-element skills. 398
• Used sustained Holy Light Illumination with Sunflower Immortals to expose and eliminate modified Shadow Beasts. 398

Gu Poison Manipulation

After contracting the Blood Gu Butterfly, Zhang Lingxue inherited its Gu Poison Manipulation skill. 64

• Uses the Blood Gu Butterfly's abilities to address the Blood Gu infecting Zhang Dashan. 80
• Kept the Gu-contaminated blood sample under layered containment and prepared the Goddess of Light Butterfly's Purification skill as a safeguard. 64
