Summary

1. Key plot points and events: Lu Zhou claims the completed task "Career Beginning" in the system, receiving a B evaluation because his assets (80% equity of Campus Assistant plus school prize money) reached 5 million RMB. He gains 5,000 free XP, 500 points, and a lottery spin. He invests XP to level up multiple sciences (Biochemistry, Materials, Energy to Level 1; Informatics to Level 1 with extra XP remaining). The lottery yields a can of Sprite (junk) despite his face-washing ritual, frustrating him. He then reviews three new tasks: (1) Series A financing (20M+ RMB), (2) becoming a librarian (ignored as low-reward and a joke), and (3) completing a research project resulting in at least one patent, which offers "Inspiration Time" — a mysterious reward that piques his curiosity. He chooses Task Three.
2. Character developments: Lu Zhou demonstrates strategic resource management (balanced XP allocation) and forward-looking thinking, prioritizing a potentially higher-reward research task over an easy but "trap" librarian task. His frustration at the lottery shows a human, relatable side. He shows determination to pursue academic research if the required project is viable.
3. Significant themes: The system's task chains and reward logic; the contrast between gambling (lottery) and systematic progress; the value of research and intellectual property over trivial tasks; the absurdity of luck (the Sprite can, mocking the common superstition in the title).
4. Character interactions: Mostly internal monologue; Lu Zhou briefly references his roommates (Liu Rui, Huang Guangming) being at the gym. There are no direct dialogues, as the chapter focuses on his solo decision-making within the System Space and his reaction to rewards.

• The mission receives an A rating, granting him 10,000 Mathematics EXP, 3,000 Physics EXP, 3,000 Materials Science EXP, 500 points, and 24 hours of "Inspiration Time."
• He reflects on why this reward was so high: the system calculates experience based on research project value (a two-billion-yuan engineering contract) plus his contribution, rather than just the paper's academic value. He also suspects Zhou's Conjecture mission had a "reward reduction" due to being a system-issued blueprint.
• Lu Zhou checks his status panel, noting Physics is nearly level 2 (5100/10000).
• He decides to pursue dual degrees in Mathematics and Physics, adjusting his leveling plan accordingly.
• He reviews three new missions:
  1. "Slam Dunk Master" — 3,000 three-pointers and 50 dunks (junk reward, low payoff).
  2. "Two-Front War" — register for two national-level competitions simultaneously.
  3. "Befriend Through Learning" — attend an academic conference, give a presentation, display a poster, interact with experts.
• He rejects Mission 1 as a waste of time and chooses Mission 3 over Mission 2, because he already has an invitation to Princeton's Mathematics conference in early February, where he can give a 30-minute presentation.
• He plans his preparation: build a PPT, create an academic poster per organizer requirements, and improve his spoken English. He also considers taking the TOEFL, reasoning that more certificates never hurts a top student.

2. Character Developments

• Lu Zhou: Shows strategic thinking, weighing costs versus rewards and planning long-term (dual degrees). He is intellectually ambitious, deciding to improve his spoken English and add the TOEFL certificate to his credentials. He is also pragmatic, saving his Inspiration Time for difficult problems.
• Roommates (Shi Shang, Huang Guangming, Liu Rui): Act as comic relief, reinforcing Lu Zhou's "big shot" status. They are casual, teasing, and enjoy gaming together, providing a contrast to Lu Zhou's intense academic focus.

• Zhang Hai (taxi driver) & Lu Zhou: Fellow-townsman rapport; exchanged banter about safety and the unexpected possibility of "female robbers"; gives Lu Zhou his business card for future rides.
• Molina Abel & Lu Zhou: First meeting; she initiates conversation, remarks on his proof being praised even by Deligne, says she's "looking forward to your speech" and has "prepared some questions," then walks with him to his accommodation.

Chapter Summary: “A Moment to Witness History?”

Key Plot Points and Events

• Molina escorts Lu Zhou to the Princeton Hotel before leaving him to settle in. Exhausted from his flight and journey from Philadelphia, Lu Zhou showers and immediately falls asleep.
• The mathematics conference is unusually prestigious and lasts six days, attracting prominent mathematicians and researchers. Lu Zhou is scheduled to give a thirty-minute presentation on his research into the distribution law of Mersenne primes on the fifth day.
• Lu meets his senior brother, Luo Wenxuan, outside the hotel. Luo accompanies him to Princeton University and explains that although he mainly studies functional analysis—particularly Hilbert spaces—he has also explored quantum mechanics and quantum field theory.
• Luo praises Princeton’s mathematics and physics departments but advises Lu not to switch into mathematical physics, calling it a difficult and potentially distracting path compared with Lu’s promising work in number theory.
• At the conference, Lu observes the informal and egalitarian atmosphere of the poster sessions, where scholars of different backgrounds freely exchange ideas. Luo quickly disappears to attend lectures and pursue academic opportunities independently.
• Lu collects conference souvenirs but remains focused on studying the scheduled presentations and researching the latest developments in mathematics.
• While browsing the posters, Lu discovers one titled “Proof of the Twin Prime Conjecture,” authored by someone named Dijan. Since Lu has been working on the same problem for months, he is shocked and excited by the possibility that someone else has solved it.
• The chapter ends with Lu approaching the seemingly unattended poster, eager to determine whether the claimed proof is genuine and whether he is witnessing a major moment in mathematical history.

Character Developments

• Lu Zhou is shown as highly dedicated and academically ambitious. Despite exhaustion and the distractions of the conference, he quickly focuses on learning and evaluating cutting-edge research.
• His confidence is balanced by humility: he recognizes the significance of being invited to speak as an undergraduate and remains aware of his relatively junior status among the attending scholars.
• Lu also displays curiosity and competitiveness when he encounters the alleged proof of the Twin Prime Conjecture. His shock reflects how personally important the problem has become to him.
• Luo Wenxuan is introduced as warm, enthusiastic, and academically experienced. He serves as a supportive senior figure while also offering practical guidance about Lu’s future research direction.
• Luo’s willingness to attend fields outside his specialty emphasizes his broad intellectual interests and appreciation for major academic opportunities.

Significant Themes

• The pursuit of knowledge: The conference is portrayed as a place where ideas, rather than social status, are exchanged and tested.
• Academic opportunity and recognition: Lu’s invitation to present highlights the importance of professional reputation and the prestige attached to major conferences.
• Competition and discovery: The apparent solution to the Twin Prime Conjecture introduces the possibility that Lu’s own work may have been preempted, creating tension between admiration, disappointment, and competitive urgency.
• Intellectual freedom and collaboration: The informal poster sessions symbolize open debate, where anyone with a worthwhile idea can participate.
• Choosing one’s path: Luo’s advice raises the question of whether Lu should remain in number theory or pursue the broader challenge of mathematical physics.

Important Character Interactions

• Lu Zhou and the academic community: Although he has not yet engaged deeply with other scholars, his movement through the conference demonstrates his willingness to seek out ideas and participate in serious mathematical exchange.
• Lu Zhou and Dijan’s poster: The final encounter creates the chapter’s central mystery: whether Dijan has truly solved the Twin Prime Conjecture and what that means for Lu’s own research.

Chapter Summary: “Gentlemanly Conduct”

Key Plot Points and Events

• Lu Zhou meets Dijan, an Indian mathematics student from Nehru University, who is presenting an attempted proof that there are infinitely many twin primes.
• Dijan claims that Princeton mathematicians have rejected his work because of prejudice against an Indian researcher. He explains that his proof uses Reverse Mathematics rather than the more conventional algebraic methods associated with Zhang’s bounded-gap work.
• Dijan’s argument assumes that there are finitely many twin-prime pairs and identifies a largest pair ((P_{n-1}, P_n)). He then constructs:
  [
  P=P_1P_2\cdots P_n+1
  ]
  and argues that both (P) and (P-2) must be prime, producing a larger twin-prime pair and creating a contradiction.
• Lu Zhou identifies the fatal flaw: the construction does not guarantee that (P) is prime, only that it is not divisible by the primes up to (P_n). He demonstrates this with (2\cdot3\cdot5\cdot7\cdot11\cdot13+1=30031=59\cdot509).
• Dijan realizes his basic error, becomes humiliated, tears down his presentation, and leaves while nearby spectators react with amusement and applause.
• After the crowd disperses, Lu Zhou speaks with Molina, the blonde woman who helped him find his hotel. She teases him for defeating another contestant on his first day.
• Molina explains that presenting at Princeton requires not only intelligence but also the emotional resilience to withstand criticism. She gives Lu Zhou a piece of gum and jokingly asks for his email and Facebook account in return, calling this exchange “gentlemanly conduct.”

Character Developments

• Lu Zhou demonstrates strong mathematical reasoning, quick mental calculation, and a willingness to challenge flawed logic directly. Although he is not trying to embarrass Dijan, his blunt correction unintentionally exposes Dijan’s incompetence before an audience.
• Lu Zhou also shows restraint: he initially avoids provoking Dijan and recognizes that Dijan’s broader conceptual approach—thinking outside established methods—is valuable despite its error.
• Dijan is portrayed as proud, defensive, and eager for recognition. His resentment toward Princeton’s mathematical community makes him interpret their rejection as prejudice. When his mistake is exposed, his confidence collapses into embarrassment and anger.
• Molina becomes more familiar and playful with Lu Zhou. She observes his interaction with Dijan, appreciates his intelligence, and begins establishing a friendly, possibly flirtatious relationship through humor and the exchange of contact information.

Significant Themes

• Logic versus assumption: The chapter emphasizes that a proof can appear elegant while still relying on an invalid assumption. Dijan mistakes “not divisible by known primes” for “being prime.”
• Mathematical rigor: Creativity and unconventional methods are encouraged, but every step must withstand careful verification.
• Pride and humiliation: Dijan’s arrogance and insecurity contribute to his public downfall, while Lu Zhou’s calm confidence contrasts with his emotional reaction.
• Intellectual resilience: Molina stresses that success in a competitive academic environment requires the ability to endure criticism and public failure.
• Cultural and academic prejudice: Dijan believes Princeton rejects him because he is Indian, raising the possibility of bias while also suggesting that his wounded pride may distort his interpretation of events.
• Social connection and flirtation: Molina’s gum and request for Lu Zhou’s contact information transform a tense mathematical encounter into a lighthearted personal exchange.

Character Interactions

• Lu Zhou and Dijan: Their conversation begins cordially but becomes a public mathematical confrontation. Lu Zhou listens to Dijan’s proof, identifies its flaw, and unintentionally humiliates him.
• Lu Zhou and the crowd: The spectators initially ignore Dijan’s poster but gather once Lu Zhou begins following the proof. They react with amusement and quiet applause when Lu Zhou reveals the counterexample.
• Lu Zhou and Molina: Molina watches the exchange and teases Lu Zhou afterward. Their conversation reveals mutual curiosity and growing familiarity, ending with a playful bargain over contact information.
