First Appearance	31

Appearance

• Described as having exceptional looks and bearing; factory owner Li Yang initially assumes that she and Yan Xiao may be wealthy heirs 50.
• Has delicate, “jade-like” fingers 48.
• Blushes intensely when she realizes she is still holding Yan Xiao’s hand after pulling him away from Chu Yang 36.

Personality

Fangxin is intellectually curious and careful about evidence. When Yan Xiao introduces his theories about insect phototaxis, she searches Zhiwang for related research and questions him after finding no papers on the topic. She explains that their competition submission will need experimental methods and results, rather than unsupported claims 31.

She has a strong sense of fairness. Initially, she refuses to join Yan Xiao’s paper because she believes she would be taking credit for work she did not perform. She accepts only after he assigns her meaningful responsibilities and promises that she can decline a share of the prize money. Her concern for professional ethics also leads her to keep unpublished research confidential and question Yan Xiao’s misleading factory-bidding scheme 31 36 50.

Persistent and competitive, she repeatedly pushes Yan Xiao to finish their research and take studying seriously. Her mock-exam challenge is partly an attempt to keep his talent from going unused. She also rejects his existential nihilism, favoring her father’s advice to live fully and without regret 42 43.

Her growing affection for Yan Xiao appears through enthusiastic praise, hand-holding, shared meals, and pride in his achievements. She is genuinely happy about his literary award without asking how much money he received, but becomes hurt when he jokingly claims to have been talking to another girl 43 48 49.

Abilities & Skills

Research and Scientific Writing

• Searches academic databases and identifies the need for experimental evidence 31.
• Takes the lead in writing their insect-phototaxis paper and works with Yan Xiao on revisions 38 41 42.
• Proposes sending captured insects to the Agricultural College for identification 38.
• Clearly presents the experiment’s methods and results in a video submitted with the paper 45.

Project Coordination

• Contacts suppliers and arranges delivery of blacklight equipment 36.
• Recruits classmates to help assemble six insect traps 37.
• Secures her father’s assistance with fieldwork, transport, and access to laboratory resources 37 49.
• Coordinates communication with the competition judges and ensures Yan Xiao attends their meeting 44 46.

Academic Ability

• Has a strong mock-exam record, though Yan Xiao’s earlier perfect score exceeds hers 33 42.
• Enters the second district mock exams specifically to compare their performance on the same papers 42.
• States that she does not need to take the college entrance examination; the reason is not explained in the provided chapters 31.

Story Role / Major Arcs

Forming the Research Partnership

Fangxin is preparing an entry for the National Agricultural Science Essay Competition when she meets Yan Xiao. His explanation of four possible causes of insect phototaxis persuades her to reconsider her nearly completed paper. They agree to collaborate: he supplies the research direction, while she helps organize data and write the submission. The competition’s reported one-million grand prize is a major incentive for Yan Xiao, but Fangxin is initially more concerned with earning her authorship fairly 31 33.

They design a comparison using five types of lamps and insect-catching electric grids. Obtaining a suitable blacklight—approximately 330–390 nm—becomes their main equipment problem. Fangxin researches lighting technology and asks her father for help 32 33.

The Changping Field Trial

After a supplier mistakenly delivers an entire salon machine rather than just bulbs, the pair obtain the blacklight components they need. Fangxin organizes classmates to assemble six traps and arranges an overnight test in pest-infested farmland in Changping. Lin Wushu accompanies them and recommends a no-light control, repeated trials, and analysis of the insect species caught 37.

The blacklight trap produces a much larger catch than the other lamps:

Lamp Type	Recorded Insect Catch
Halogen	0.92 kg 38
LED	0.51 kg 38
Tungsten filament	0.81 kg 38
Ordinary ultraviolet	0.45 kg 38
Blacklight	11.62 kg 38

Fangxin celebrates the result and proposes further identification of the insects. She takes responsibility for the paper while Yan Xiao pursues patent protection for the device. Their stated goals include reducing pesticide use and using captured insects as feed or fertilizer 33 38.

Competition Review

After sustained revisions, they submit Research and Preliminary Exploration of Insect Phototaxis. Fangxin’s presentation in the accompanying video reports a catch of 11.62 kg over nine hours, prompting judge Zhao Xiaolei to reconsider his initial skepticism 42 45.

The evaluation panel considers the paper a possible Outstanding Paper Award contender but requires verification before making a decision. Fangxin clears up the school secretary’s suspicion that the judges’ call is a scam and repeatedly phones Yan Xiao to arrange the meeting—leaving him with 96 missed calls 44.

At the meeting, she defers to Yan Xiao as first author when the judges request another demonstration. He postpones it for at least a week while specialized equipment is manufactured; Fangxin notices that his explanation about the original equipment being broken seems strange. No competition award or completed verification trial is documented by Chapter 50 46 50.

Academic Rivalry and Prototype Development

Fangxin challenges Yan Xiao to the district mock exams to encourage him to work harder. Their wager eventually increases to a month of meals, with the winner choosing the restaurants; the result remains unrevealed in the provided chapters 42 43 50.

She continues supporting the invention by obtaining her father’s promise of a laboratory and an operator as a backup. She also accompanies Yan Xiao to equipment-housing manufacturers, where she questions the honesty of his bidding presentation 49 50.

Relationships

• Yan Xiao — Classmate, research partner, academic rival, and developing romantic interest. Their collaboration grows into affectionate teasing and frequent meals together. Fangxin considers the possibility of studying alongside him and becoming a couple, but no formal relationship is established in the provided chapters 31 42 48 49.
• Lin Wushu — Father and prominent scientist. He supplies research resources and methodological advice while keeping a protective eye on her closeness with Yan Xiao. Fangxin follows his advice to explore subjects before choosing a major 37 48 49.
• Cao Ruiying — Grandmother and Yan Xiao’s physics teacher. She tells Fangxin about Yan Xiao’s academic ability; Yan Xiao partly invites Fangxin into the project to repay Cao’s kindness 31.
• Wu Xiaohong — Academic acquaintance who offers to help locate a suitable lamp and teases Yan Xiao about potentially becoming Cao Ruiying’s grandson-in-law 32.
• Chu Yang — School acquaintance whom she avoids because he tells disgusting jokes during meals 36.
• Zhao Xiaolei — Competition judge who takes their paper seriously after viewing its evidence and requests an in-person demonstration 44 45 46.
