Background / History

Ding Junyi was the chief scientist of the Federation's Underground City No. 9 biology laboratory. During the underground city's crisis, she remained composed while analyzing surveillance footage of the Infinite, correctly identifying its locomotives, modified passenger carriages, armor, and likely capabilities from limited visual evidence 96.

She led the surviving researchers in preserving their research data before opening the sealed exit. When Lin Xian's team arrived, Ding Junyi identified herself, assessed the air-warning system, and helped secure the researchers' rescue from the underground city 101. She subsequently provided Lin Xian with information about the Level 5 cargo terminal and the Gemini 11R nuclear-powered electric locomotive 103.

After boarding the Infinite, Ding Junyi chose to remain with Lin Xian's group rather than return to the Federation. She formally resigned from her Federation position when Supervisor Taylor attempted to reclaim Federal research assets and the rescued disaster plant 143.

Appearance

Ding Junyi is a tall, slender woman with refined features and an intellectual, cool demeanor. She is typically seen in laboratory attire, reflecting her constant research work 101 210.

• Usually wears glasses, including gold-rimmed frames during her first meeting with Lin Xian 101.
• Commonly wears a white lab coat with jeans and short heels 101.
• Her ability initially manifests as a small green sprout that can bloom into a pink flower atop her head 213.
• Later manifestations include glowing vines and plant matter that can form protective clothing around her body 497.

Personality

Ding Junyi is calm, analytical, and exceptionally direct. Even during the underground city's collapse, she focuses on verifiable information, risk assessment, and the practical value of people and resources 96 101. Her colleagues note that she can appear emotionally detached or lacking in social tact, but her rational communication helps keep others focused during crises 101 118.

As a researcher, she is methodical and highly disciplined. She keeps backups of her work, maintains a meticulous living space, and continues studying dark creatures even amid active threats 172 210. Her scientific curiosity extends to dangerous or controversial subjects, including disaster plants, dark energy, high-dimensional phenomena, and the biology of eerie entities 283 480 498.

Despite her clinical manner, Ding Junyi becomes personally devoted to Lin Xian and the Infinite. She regards Lin Xian as both her employer and chosen partner, and states that she will support his decisions even when her scientific conclusions differ from his personal stance 172 239.

Abilities & Skills

Plant-Type Ability

Ding Junyi can sense, accelerate, reshape, and control plant life. Its earliest known manifestation was a sprout and pink flower growing from her head after the Hell Black Chrysanthemum affected her 213.

• Accelerates cultivated crops, enabling rapid production of vegetables and other plants aboard the train 243 295.
• Detects an affinity or “scent” from plants through mental focus 243.
• Alters plant structure to create abnormal elasticity, hardness, strength, and tensile force 316.
• Produces dense vines capable of restraining equipment, protecting personnel, and stabilizing objects during emergencies 472.
• Develops Blood Vines with sharp thorns and rapid proliferation potential 465.
• Her ability does not significantly strengthen her physical body, leaving her vulnerable in direct combat without protection 497.

Dark-Energy Affinity

Her plant ability is closely connected to disaster plants and dark energy.

• Can absorb black-smoke energy, though she remains uncertain of its long-term effects 297.
• Attempted to communicate with the Hell Black Chrysanthemum, but the effort overwhelmed her and caused unconsciousness 283.
• Uses plant connections to enter an altered state associated with a higher-dimensional perspective 497.
• The process can impose severe mental and physical strain, including comatose states and dangerously elevated ability fluctuations 346 497.

Biological and Evolutionary Research

Ding Junyi is one of the Infinite's primary scientific analysts, specializing in biology, disaster plants, evolution, and eerie entities.

• Conducts monitoring of the train personnel's physical condition and evolution patterns 172 340.
• Studies the Hell Black Chrysanthemum, Silver Dragon Ten Thousand Mistakes, Blood Calamity Disaster Plant, and other anomalous flora 165 315 340.
• Identifies the relationship between Dark Marks and nearby eerie entities, offering methods to remove or avoid their effects 194 231.
• Determines that eerie entities use processed human and animal tissues, rather than functioning as conventional organisms 340 387.
• Hypothesizes that ability users and eerie entities share an origin in dark energy, with human abilities potentially representing a diffraction of higher-level entities onto Earth life 498.

Equipment / Items

• Research Carriage No. 3 — Her main laboratory and workspace aboard the Infinite 172.
• Plant cultivation facilities — Used for soilless cultivation, plant-growth experiments, and disaster-plant containment 243.
• Spirit Purge Value Detector — Used to measure ability fluctuations and monitor evolution 480 506.
• Hell Black Chrysanthemum — A disaster plant central to much of her research on dark energy, marks, and evolution 172 283.
• Silver Dragon Ten Thousand Mistakes — A second disaster plant kept under observation in her cultivation facilities 315 340.

Relationships

• Lin Xian — Leader of the Infinite, research collaborator, and Ding Junyi's chosen partner. She joins his side after leaving the Federation and consistently supports his final decisions 143 172 239.
• KIKI — Research partner during investigations, including the Shijiu Lake submersible discovery. Their exchanges contrast Ding Junyi's principle-based thinking with KIKI's emotional responses 239.
• Zhao Yan — Former colleague from Underground City No. 9. Zhao Yan respects Ding Junyi's composure but is often frustrated by her blunt manner 101 143.
• Xu Wen — Former colleague and fellow survivor from the Biological Research Department 101 143.
• Chen Sixuan — Fellow Infinite member who provides rear support and protection when Ding Junyi is exposed to danger during field operations 240.

Story Role / Major Arcs

Underground City No. 9

Ding Junyi analyzes the Infinite before Lin Xian's group enters the underground city, helps organize the evacuation of the surviving researchers, and preserves crucial biological-research data 96 101.

Joining the *Infinite*

She provides operational information about the underground city's facilities, moves into the train's research carriage, and becomes responsible for biological analysis, cultivation projects, and evolution monitoring 103 172 243.

Federation Break

When the Federation investigation team attempts to seize the Hell Black Chrysanthemum and other assets, Ding Junyi formally resigns from the Federation and sides with Lin Xian 143.

Disaster Plant and Dark Mark Research

Ding Junyi investigates the Hell Black Chrysanthemum's reactions to dark creatures, develops theories concerning Dark Marks, and examines the ecological conditions that allow disaster plants to grow during Polar Night 194 231 283 316.

Evolution Research

Her work expands from monitoring the crew's evolution to examining the shared biological basis of humans, dark energy, and eerie entities. Her hypothesis that ability users and eerie entities may originate from the same system becomes a potentially strategic discovery for humanity 340 387 498.
