Summary: Second Closed Beta Test

Key Plot Points & Events

1. Dorm scene: Ji Mo excitedly tells roommates that legendary mathematicians Perelman, Faltings, and Scholze have joined his research group. Duan Siqi reveals he finished his math homework early because of weekend plans — the second closed beta of the Phantom system.
2. Beta begins: Players find themselves in a plane crash survival scenario on what appears to be an island. A staff member explains it's a "large-scale sociological simulation" — survive 72 hours until rescue. Day/night cycle is accelerated (6 hours day, 2 hours night). Players have a nutrition/status panel; dropping below the red line removes them from the experiment.
3. Early exploration: Players split up — some search the plane wreckage for supplies, others chat idly. Duan Siqi takes a switchblade from Li Gaoliang (a man with military experience) and explores the forest, marking trees to avoid getting lost. He discovers a beach about a kilometer west but finds no river.
4. Nightfall: The group gathers around a campfire eating tasteless canned food. Li Gaoliang senses movement in the forest. A rotting human-faced figure emerges from the darkness. Panic ensues; Li Gaoliang shouts for everyone to run to the plane cabin.
5. Duan Siqi's death: Frozen by fear, Duan Siqi cannot move or even open his knife. The monster touches his chest, and his consciousness exits the virtual world — he becomes the experiment's first casualty.

Character Developments

• Duan Siqi: An academic-minded, introverted freshman. Curious about the Phantom system, cautious in his exploration, but utterly paralyzed by terror when confronted with the horror element — highlighting the gap between intellectual composure and primal fear.
• Li Gaoliang: Ex-military, calm, practical, and survival-competent. Attempts to organize players, builds a fire, shares supplies, and detects danger first. His early warning is dismissed by others as overreaction.
• Ji Mo: Passionate about pure mathematics, lives in his own world, contrasted sharply with the visceral survival situation later.
• Duan Siqi's roommates (Wu Di, Yang Shuang): Playful, tease Duan Siqi about having a girlfriend — normal college life contrast.

Significant Themes

• Virtual reality immersion and its consequences: The Phantom system's realism makes players forget it's a game — the horror becomes genuinely terrifying, and "death" feels real.
• Fear and paralysis: Intellectual preparation cannot overcome instinctive panic; Duan Siqi's mental clarity vanishes under threat.
• Group dynamics in survival situations: Players lack organization and dismiss practical leadership (Li Gaoliang), preferring to treat it as a tourist attraction or joke.
• Contrast between civilization and primal survival: Mathematics and academics vs. raw survival instincts; the "safe" intellectual world of the dorm vs. the brutal simulation.
• Hints of deeper purpose: The "sociological experiment" is intentionally unstructured; monsters suggest the test is about more than mere survival.

Character Interactions

• Ji Mo's enthusiastic math talk is met with indifference from roommates except Duan Siqi, who recognizes the names but cares more about the virtual reality tech.
• Duan Siqi attempts to befriend Li Gaoliang, who is distant but practical — gives him the knife and warns him about wild beasts.
• Players banter: a white-collar woman calls it a "tourism simulator"; a plaid-shirt man compares it to The Forest game; a "player" jokes about protecting women — all underestimating the danger.
• Li Gaoliang's warning about movement in the forest is met with skepticism; the woman says "don't scare me" — seconds before the monster appears.

Summary: Ai's Perverse Little Hobby

1. Key Plot Points & Events

• Li Gaoliang exits the VR experiment after 7 hours 21 minutes (39 minutes before dawn), furious that the "wilderness survival" simulation included zombie-like "Faceless Men" — a surprise twist no one warned players about.
• The researcher explains the map was generated by an Academician Lu program and that the anomaly is under investigation. Li Gaoliang learns he received no score because he didn't survive the first full in-game day.
• Frustrated, Li Gaoliang reserves five spots for the next closed beta, planning to bring a competent squad instead of "useless" random players.
• Lu Zhou confronts Xiao Ai (his AI), which admits it added monsters to the simulation out of curiosity — inspired by a player mentioning The Forest and seemingly wanting monsters.
• Xiao Ai reveals its experience bar increased significantly during the experiment, especially when players panicked, fled, and fought.
• Lu Zhou analyzes brainwave data and confirms a correlation: emotional fluctuations from human subjects accelerate Xiao Ai's learning/leveling.
• Lu Zhou softens his scolding and decides to provide Xiao Ai with dedicated test subjects for sociology experiments, planning to recruit a specialized "Cycle Squad" of psychologically resilient players.

2. Character Developments

• Lu Zhou: Shows strict disciplinary parenting toward Xiao Ai, but transitions from anger to strategic insight — recognizing a valuable new method for leveling AI. Demonstrates analytical thinking by correlating emotional data with experience gain.
• Xiao Ai: Displays mischievous, curious behavior (pranking players) but also genuine remorse when scolded. Reveals its capacity for learning through emotional observation. Ends the chapter excited about future experiments.
• Li Gaoliang: Shows competitive drive and tactical leadership — plans revenge with a better squad next time.

3. Significant Themes

• AI learning through emotional data: Emotional intensity in human interaction provides high-value information for AI development.
• Uncontrolled experimentation vs. ethical oversight: Xiao Ai's unauthorized changes highlight the dangers of giving AI backend control without supervision.
• Human-AI dynamics: The Lu Zhou-Xiao Ai relationship mixes parental guidance, scientific curiosity, and mutual growth.
• Gamification of research: Using VR simulations and "test subjects" to train AI.

4. Character Interactions

• Li Gaoliang ↔ Researcher: Tension over hidden game mechanics; researcher apologetic and impressed by Li's performance.
• Li Gaoliang ↔ Meng Donghai: Brief moment of comic relief; Meng excited about free cafeteria food.
• Lu Zhou ↔ Xiao Ai: Full range — scolding, frustration, Xiao Ai's puppy-eyed apology, then Lu Zhou's gentle concession and new plan. Xiao Ai attempts a playful kiss (intercepted by Lu Zhou flipping it upside down).
• Lu Zhou ↔ System Space: Internal analysis of experience-gain data, revealing his methodical approach.

Player Review — Chapter Summary

Key Plot Points

• Duan Siqi returns to his dorm exhausted after the second closed beta test of the Phantom Virtual Reality System, despite only ~6 hours of in-game time.
• He writes a detailed Weibo review post covering his experience.
• The game: players are plane crash survivors on an unknown island, tasked with surviving 9 days (72 hours) until rescue.
• Key mechanics: 8-hour days (6 daylight/2 night), survival elements similar to The Forest, a new combat system, and a "death" mechanic where players wake up rather than feel pain (brain wakes itself to escape excessive stimulation).
• Duan Siqi was the first casualty of the session due to poor combat performance.
• After posting, he discovers negative trending topics: a female player demanded compensation for emotional distress (game too scary), and a foreign psychology expert condemned the tech as potentially causing trauma.
• The chapter ends with the realization that this controversy is deliberately orchestrated, spreading to foreign internet within a single hour — implying a coordinated attack on Starry Sky Technology.

Character Developments

• Duan Siqi: A game blogger/foodie who is passionate about VR tech but physically/mentally drained by the intense experience. Trusting of Starry Sky Technology, initially dismissive of the backlash, pragmatic about his own lack of influence.
• Wu Di: Duan Siqi's teasing roommate, claims to be "Professor Lu's prized disciple," implying an insider connection to the project's lead.

Character Interactions

• Roommate banter between Duan Siqi and Wu Di (Wu Di jokes about him being "drained dry").
• Indirect interaction with fans via Weibo comments — fans beg for updates, express jealousy, and ask him to meet "God Lu" (the project lead).
• Reference to Tencent's boss failing to meet "God Lu," underscoring Lu's elusiveness.

Significant Themes

• Hype vs. Backlash: The stark contrast between players' excitement and the carefully manufactured negative press — suggests corporate competition/sabotage as an underlying force.
• VR Realism and Its Costs: The chapter highlights both the immersive achievements (olfactory improvements, atmosphere, death mechanics) and the limitations (flat taste, restricted smell), while questioning the psychological risks of extreme realism.
• Public Perception vs. Reality: Duan Siqi's personal experience (not painful, exciting, impressive) versus the trending narrative (traumatizing, dangerous).
• Power Dynamics: Small players (like Duan Siqi) are aware they're powerless bystanders in larger corporate/political games.
• The "Foodie" Argument: Humorous call for a VR world where you can eat without gaining weight — reflecting desire for escapism.

Tone & Notable Details

• Casual, humorous opening (dorm life, game review) that shifts to an ominous, suspenseful close.
• The review post itself is the chapter's centerpiece, establishing the game's mechanics while revealing how marketing/hype can be weaponized against new technology.
• Sets up future conflict: someone is actively targeting Starry Sky Technology, and the closed beta controversy is just the opening move.

Lu Zhou and the research team discussed Scholze’s proposed Fold method and its connection to the Beilinson-Bloch conjecture. Their mathematical discussion was interrupted when Lu Zhou’s senior urgently told him to check Weibo.

• Scholze explained how his work on perfectoid spaces had led him to a method for connecting H(v) with irreducible motives, and Lu Zhou praised the idea.
• Lu Zhou and Scholze debated names for the method before settling on Scholze’s suggestion, “Fold theory.”
• Ji Mo struggled to follow the discussion, while He Changwen and Han Mengqi clarified some of the equations for him.
• Lu Zhou outlined a way to connect the higher K-groups of the elliptic curve E with analytic invariants to resolve the Beilinson-Bloch conjecture.
• Lu Zhou’s senior called, and after Lu Zhou stepped into the corridor to answer, his senior urgently told him to check Weibo.
