Devin looked at hundreds of first-grade royal knights attacking a small base. The two S Grade Commanders easily captured Rorand and saved all the female captives.
In the novel, this was a tough battle as they got a clue about this base a week later. Kawki failed to gather information about the strength of these people, and Commander Yu was the only S Grade person to attack the base. A week later, Rorand was successfully promoted to S Grade, and Kawki's failure made Rorand alert, complicating the mission, leading to the deaths of many royal knights and even Commander Yu.
However, Devin found a clue in two days. Commander Yu successfully obtained all information about this group without alerting them. He also called another commander, raising the strength, and the rescue mission was successfully completed.
Devin was quite satisfied with the results. He looked at Kitsuneia, massaging her red wrist as she walked over with an expressionless face.
