Chapter Summary: “Solo Kill”

1. Key Plot Points and Events

• Fu Junlin and the voice in his mind attempt to use various weapons against the Minotaur BOSS.
• Their first efforts are disastrous: throwing a Gatling gun at the Minotaur accomplishes nothing, while firing the sniper rifle’s powerful shot knocks Fu Junlin out of the tree and sends the bullet wildly off target.
• Spectators mock Fu Junlin, believing he is useless and merely providing comic relief.
• Miao Ningxue urges the teacher to force Fu Junlin to die and return, arguing that continuing the fight wastes energy and further damages Class Three’s reputation.

Significant Themes

• Systemic discrimination: Subspecies are openly mistreated by authorities and society, with Fu’s low genetic status causing the police to assume guilt and justify violence.
• Powerlessness and restraint: Fu and Shi both understand that anger alone cannot overcome an unequal system. Resistance without sufficient power may bring harsher consequences.
• Poverty and survival: Fu lives in a cramped shantytown and works manual energy-production shifts despite being a gifted student, emphasizing the economic hardships he faces.
• Determination and self-improvement: Fu continues working, studying, and planning for a Mecha Master career rather than allowing humiliation to derail him.
• Compassion amid hardship: Fu’s gift to Shi shows that generosity and personal bonds survive even in a harsh, unequal society.
• Different paths of healing and strength: The discussion of Instant Healing and Slow Healing reflects the broader theme that abilities and professions have different strengths, limitations, and specialized uses.

Chapter Summary: “There Will Definitely Be a Problem”

Key Plot Points and Events

• Fu Junlin continues repairing and examining Battle-Flag Crystal Blocks with Uncle Wen, while Big Black assists through its “Biological Vision,” which allows it to sense the crystal’s internal circuits.
• The factory owner, Zhang Cheng, introduces Pi Yi’an as the new technical director. Pi has brought two small components called Capacity Expanders:
  • The blue component increases crystal capacity by 20%.
  • The red component supposedly improves output power by over 16% while stabilizing and cooling the system.
• Zhang announces that the factory will stop production for the day so the existing crystal blocks can be modified and the new technology can be introduced the following morning. Workers are given blueprints to study.
• After examining the blueprints, Fu Junlin notices a serious flaw. The circuit connected to the red stabilizing component lacks a sufficient stability coefficient. Repeated use would weaken the circuit, causing it to crack and potentially trigger an explosion after several operating cycles.
• Fu reports his concern to Wang Kai, the supervisor of the C6 production line. Wang initially struggles to verify the calculations but trusts Fu’s judgment and decides to bring the issue to Zhang Cheng.
• Fu worries that challenging the new technology could offend Chen Changming, who helped bring Pi Yi’an to the factory and may have hidden financial motives. He fears losing his only job.
• Wang reassures Fu that he will receive credit if the warning is correct and will not be blamed if it proves mistaken. As Fu leaves, however, he turns back and firmly insists that the data cannot lie: there is definitely a problem.

Character Developments

• Fu Junlin demonstrates strong technical ability, careful observation, and a deep sense of responsibility. Although he lacks confidence and considers himself an ordinary worker rather than a “top student,” his calculations reveal exceptional expertise.
• Fu’s cautiousness is emphasized. His difficult circumstances and dependence on his job make him hesitant to challenge powerful figures, even when he knows he is right.

• Pi Yi’an is introduced as the new technical director, but the chapter leaves his competence and motives uncertain.
• Chen Changming is indirectly portrayed as potentially untrustworthy because of his connection to Pi and the expensive new components.

Significant Themes

• Truth versus self-preservation: Fu must choose between protecting his livelihood and warning others about a dangerous technical defect.
• The value of evidence: Fu relies on calculations and observable data rather than status or authority. His belief that “the data won’t lie” becomes the chapter’s central principle.
• Class and power differences: A low-ranking worker may have discovered a serious mistake made by influential technical and managerial figures, but speaking up could endanger his future.
• Hidden danger beneath apparent progress: The Capacity Expanders promise greater efficiency and productivity, yet their flaws may lead to catastrophic failure.
