Story sequence
Rimuru travels to the Armed Nation of Dwargon because the new settlement lacks skilled builders, smiths, and textile workers. A confrontation at the city gate lands his group in custody, but the recovery of an injured guard using Rimuru's potion demonstrates the value of his cave research.
Kaijin, a famous smith under impossible delivery pressure, needs twenty long swords quickly. Rimuru uses Predator's internal analysis to reproduce completed examples, proving that his abilities can solve manufacturing bottlenecks as well as battles.
Minister Vesta tries to humiliate Kaijin and Rimuru at an elf-run establishment. Kaijin strikes him, leading to a trial overseen by King Gazel Dwargo. Gazel uses the proceeding to dismiss Kaijin while quietly allowing the craftsmen to follow Rimuru, and he punishes Vesta for letting jealousy compromise state interests.
Kaijin, the dwarf brothers Garm, Dord, and Myrd, and their practical knowledge move to the forest. Gazel's agents begin investigating Rimuru, while the king recognizes the slime's connection to Veldora and the strategic value of the emerging settlement.
Motivations
- Rimuru wants technology and skilled labor rather than treasure.
- Gazel protects Dwargon's interests while testing whether Rimuru is a threat or a possible partner.
Outcome
Tempest gains master craftsmen; Rimuru earns Gazel's attention and the basis for formal relations with Dwargon.
Consequences
- Potion replication and dwarven engineering become pillars of Tempest's economy.
- Vesta's eventual rehabilitation gives Tempest another capable researcher rather than a permanent enemy.
Power alone cannot build a nation; this is where Rimuru begins collecting institutions, expertise, and production capacity.
