• They pack up and head to the Ranoa Adventurers' Guild to collect a subjugation reward and meet Zoldat for a banquet.

She makes a cautious, indirect romantic advance through the ten-year promise, feeling both hopeful and guilty for possibly tying him down.

Key plot points and events

• Darius orders his guards not to confront Cain, whom he recognizes as the Second Sword God and a threat far greater than an S-rank Red Dragon. Acting on a warning from the White Deity, he instead plans to make Roxy disappear.
• Cain returns with Zoldat, Roxy, and the adventurers to collect the reward they are owed. When the palace guards refuse to let them in, Cain breaks down the main gate and defeats the soldiers without killing them.
• At the palace, the North King, Water King, and a King-class mage block their way. Cain identifies himself as the Second Sword God, Kayin Brand, and demands only the adventurers’ payment.
• The North King immediately backs down. The Water King tries to rely on her style’s counter to the Sword God’s Blade of Light, but Cain defeats her instantly with the back of his blade.
• Cain passes the frightened mage and confronts Darius, asking him to pay what he owes.

Character developments

• Darius is terrified of Cain and understands that provoking him could endanger the kingdom, yet he still pursues his secret plan against Roxy.
• Cain shows overwhelming power but repeatedly chooses restraint, defeating opponents nonlethally and insisting that he wants no unnecessary deaths. His straightforward focus on collecting the debt contrasts with the elaborate resistance around him.
• Roxy expresses firm support for Cain and prepares to help, while taking quiet satisfaction in the adventurers’ respect for him.
• Zoldat is eager to settle his earlier score with the Water King, but Cain’s presence determines the confrontation.

• Corruption and injustice: The adventurers must force their way into the palace simply to claim a reward they have already earned, while Darius plots against Roxy.

Character interactions

Cain’s calm demands clash with the palace’s evasive and hostile response. Roxy offers him encouragement and stands ready to assist, while Zoldat presses the claim against the nobles. Cain’s mere presence intimidates the Sword Kings; his confrontation with the Water King demonstrates the enormous difference in their abilities. The chapter ends with Cain addressing Darius directly, leaving the payment dispute—and Darius’s plan against Roxy—unresolved.

Summary: "Guiding Swordsmanship"

Key Plot Points & Events

• At the inn, Roxy critiques Cain’s Fireball, noting it holds far too much mana and would be suicidal if used in close combat. Cain acknowledges her teaching.

• To demonstrate, Cain uses a wooden sword to split a huge boulder with a lightning-fast Blade of Light.
• Cain offers three ways to train battle aura:
  1. Swing a sword relentlessly until the swordsman can sense and absorb surrounding aura.
  2. Fight Cain and learn by sensing the aura’s flow.
  3. Attempt extremely dangerous trials, beginning with surviving alone in the depths of an S-rank labyrinth.
