Ch. 41Subtraction
Chapter Summary: “Subtraction”
Key Plot Points and Events
- Chen Cheng proposes modifying Thorn Flower’s powerful, citywide defensive magic array rather than creating a new one. He reasons that Hui Dun City only needs a Platinum-Rank defense, not the original Epic-Rank protection designed for the much larger Royal Capital.
- His method, which he calls “subtraction,” involves removing every spatial-magic component that Pembez and Adolf cannot understand. The remaining, simpler sections should still be strong enough to defend Hui Dun City.
- Chen Cheng plans to use his Variable Magic to reconnect the shortened sections and maintain the flow of magical energy. Because the array has already been tested over time, he believes it will be safer and easier to maintain than an entirely new design.
- Adolf and Pembez initially struggle to accept the idea but recognize its practicality and begin streamlining the array.
- Meanwhile, Komo Huidun orders Tofis to conscript the city’s men, distribute bows and arrows, and move supplies from the storehouses to the academy. The entire academy is mobilized:
- Senior students and instructors help inscribe the defensive runes.
- Middle-year students support the city walls as auxiliary mages and medical personnel.
- Younger students prepare Mithril and transport Magic Crystals.
- An enormous undead army emerges from the forest and surrounds Hui Dun City. The city’s defenders initially panic, and some civilians attempt to flee.
- Torey, Wisdom Shield’s knight commander, executes the deserters to prevent mass panic and force the remaining civilians to hold their positions.
- The undead begin spreading around both sides of the city, clearly attempting a complete encirclement.
- Torey and the Church of Light’s knight commander order the mages to attack first. Combined elemental and Light Magic destroys large numbers of skeletons, followed by a massive volley of Mithril-tipped arrows.
- Although these attacks boost the defenders’ morale and create gaps in the undead ranks, the army’s overwhelming numbers make the losses insignificant.
- The alchemist, observing from the cliff above the city, orders the Undead Knights to launch the real assault after seeing that his psychological pressure has been weakened.
- The undead retaliate with a vast barrage of skeletal arrows. The defenders form shield walls while Light priests cast Holy Light Illumination to prevent the undead power from corroding the city walls.
- The bombardment continues relentlessly, draining the priests’ mana and placing Hui Dun City under increasing pressure.
Character Developments
- Chen Cheng demonstrates his unconventional but highly practical intelligence. Though he lacks Adolf and Pembez’s specialized magical knowledge, he applies a research-based method—discarding incomprehensible components—to simplify the defensive array.
- Adolf and Pembez show intellectual flexibility. They initially doubt Chen Cheng’s approach but quickly recognize its logic and cooperate with him.
- Komo Huidun takes decisive leadership by organizing the city’s resources and population for war.
- Tofis acts as the city’s executor of orders, immediately beginning the emergency mobilization.
- Torey reveals himself as a ruthless but determined commander. He kills fleeing civilians to prevent the defense from collapsing, yet privately acknowledges how desperate the situation is and resolves to die fighting if necessary.
- The alchemist appears calculating and psychologically perceptive. He deliberately uses the size of his undead army to frighten the defenders, then adapts when their morale recovers.
Significant Themes
- Practical knowledge versus formal expertise: Chen Cheng’s broader reasoning and research experience allow him to solve a problem that surpasses the specialized understanding of the local mages.
- Subtraction and simplification: The chapter presents removal—not addition—as the key to making a powerful but overly complex system usable.
- Leadership under crisis: The defenders must make harsh decisions, organize every available resource, and maintain morale while facing overwhelming odds.
- Fear and morale: The undead army’s greatest initial weapon is psychological. The defenders begin to recover only after successfully striking back.
- Sacrifice and authoritarian control: Torey’s execution of deserters shows the brutal measures leaders may use when survival depends on unity and discipline.
- Overwhelming numbers versus coordinated defense: The city’s magic, archery, and Light Magic are effective, but the seemingly endless undead army continues to threaten eventual defeat.
Character Interactions
- Chen Cheng explains the subtraction method directly to Adolf and Pembez, who accept his guidance despite his lesser formal magical knowledge.
- Tofis witnesses Adolf and the others following a slave’s advice and is confused, but Wisdom Shield has no time to explain.
- Komo Huidun’s orders send Tofis into action and mobilize the city.
- Adolf coordinates with the academy’s students and instructors to complete the defensive array.
- Torey and the Church of Light’s knight commander cooperate instinctively, ordering the first magical strike together.
- Torey’s harsh treatment of deserters contrasts with his later determination to stand and fight alongside the defenders.
- The alchemist observes the battle from above and directs the Undead Knights, treating the siege as both a military and psychological operation.
