• Merging Reality and Fantasy: The fantasy element (system-granted skill) is seamlessly woven into a grounded, realistic academic setting, symbolizing the “lines” of intuition behind pure calculation.

4. Character Interactions

• Zheng Hua ↔ Principal Wang: A blend of enthusiastic explanation and bureaucratic confusion, ending with the principal’s reluctant belief after hearing “full marks.”
• Principal Wang ↔ Old Yang: A serious, tactical interview where the principal probes family background and other-subject grades before committing to retain Li Dong.

• Lu Yao misunderstands Li Dong's abilities and scolds him for claiming the solution as his own.
• Li Qin, Li Dong's mother, arranges for Lu Yao to tutor Li Dong again, much to Li Dong's dismay.

Character Developments

• Lu Yao: Realizes her misunderstanding of Li Dong and feels embarrassed.
• Li Dong: Improves his math skills and becomes more determined to study.
• Yang Shengguo: Recognizes Li Dong's potential and encourages Lu Yao to apologize to him.
• Li Qin: Shows concern for Li Dong's education and arranges for Lu Yao to tutor him.

Significant Themes

• Misunderstandings and their consequences.
• The importance of recognizing and appreciating others' abilities.
• The dedication and responsibility of teachers.

Character Interactions

• Lu Yao and Yang Shengguo: Lu Yao impresses Yang Shengguo with her quick understanding of a problem, leading to a revelation about Li Dong.
• Lu Yao and Li Dong: Lu Yao's misunderstanding of Li Dong's abilities leads to a tense interaction between them.
• Li Dong and Li Qin: Li Qin arranges for Lu Yao to tutor Li Dong, much to Li Dong's dismay.

1. Key Plot Points / Events

• Li Dong is stuck on the brachistochrone problem while self-studying physics. He understands the physics but cannot derive the curve mathematically.
• He asks for help in the “Azure Dragon Study Group,” pretending the problem is for his “nephew.”
• A user named “Johann Carl Friedrich Gauss” replies, telling him to use the Beltrami Identity, which lets Li Dong solve the problem and derive the cycloid.
• Gauss then sends Li Dong a private message: “Is your side Kant’s countless worlds, or Bruno’s infinite universe?” — implying he knows Li Dong is from a different reality.
• Before Li Dong can respond, the chat window vanishes, and Gauss’s avatar turns gray/offline, suggesting a group rule has been triggered.
• Li Dong notices historical red flags: Gauss calls Johann Bernoulli “little fellow,” and Gauss seems to know the identity named after Beltrami, who wasn’t born until after Gauss’s death.
• Li Dong is terrified, then startled by a knock at the door — it’s Lu Yao.
• Lu Yao apologizes for previously misunderstanding him. She learned from Teacher Yang that Li Dong really did derive the Isomorphic Scaling Method himself.
• Li Dong brushes off the apology and instead asks Lu Yao to teach him college math. She agrees and begins mapping out the structure of a mathematics major.

2. Character Developments

• Li Dong: Shows persistence in self-study, cleverness (and mild dishonesty) in using the study group, and genuine mathematical growth. He also becomes more ambitious, wanting to learn college-level math properly. His terror at Gauss shows he is aware that the group is dangerous and mysterious.
• Lu Yao: Grows from condescending toward Li Dong to genuinely respectful. She admits her mistake, apologizes sincerely, and is willing to help him learn seriously.
• Gauss: Remains enigmatic and unsettling. He displays almost supernatural knowledge and seems to suspect or know that Li Dong is from another world/universe.

3. Significant Themes

• Mathematics as a gateway: The chapter ties physical intuition (gravity, curves) to advanced mathematical tools (calculus of variations, Beltrami identity), showing knowledge as layered and interconnected.
• Mystery and cosmic horror: The study group is not just a chat room — it may connect different realities. Gauss’s question and sudden disappearance suggest hidden rules and powers beyond Li Dong’s understanding.
• Misunderstanding and reconciliation: Lu Yao’s apology clears up an earlier conflict, reinforcing the importance of humility and second chances.
• Self-learning vs. formal education: Li Dong is an autodidact, but he recognizes the need for structured guidance, leading him to ask Lu Yao for help.

4. Character Interactions

• Li Dong ↔ Gauss: Brief but pivotal. Gauss gives a cryptic but decisive hint, then probes Li Dong’s reality before disappearing, leaving Li Dong shaken.
• Li Dong ↔ Lu Yao: Starts with Lu Yao knocking and noticing Li Dong’s strange behavior. She apologizes, he jokes it off, and then he asks for math guidance — turning her visit into a teaching session.
• Mention of parents: Li Dong and Lu Yao briefly bond over their mothers working the same weekend inventory shift, grounding the supernatural elements in everyday life.
