The manga kinda have difference with the novel about how Rimuru kill them here, i remember Rimuru kill them when they on march not when they in camp like this
When you don't want to waste time and just get the required sacrifices to level up to demon lord, spectacle isn't what you'd go for.
Love how calm Rimuru is but you can still feel his rage.
I do not like how they changed the flow around Shogo's death from the LN, but I understand why they did it for the manga. If the had followed the LN it would have been a wall of text.
