What Really Happened to the Empire’s 530,000 Soldiers in Rimuru’s Labyrinth?

They thought they were predators... unstoppable, invincible, destined to devour Tempest whole. But in That Time I Got Reincarnated as a Slime Vol. 13, Chapter 3: Dungeon Battle, the Empire’s seven-hundred-thousand-strong army learned what it truly means to be prey. This is not just a fight - it’s a slow, methodical unmaking. Magitanks, airships, surgically enhanced soldiers… none of it mattered inside Rimuru’s labyrinth. Corridors twisted like living things, shadows birthed nightmares, and every step forward was another step into the monster’s belly. From the corrosive slimes and immortal serpents to Adalmann’s undead legion, from the Insect Queen’s wasp swarm to the Eight Legions’ apocalyptic slaughter... this was war stripped of honor and mercy. The Empire’s strength became its downfall, its discipline a chain dragging it deeper. No survivors. No escape. Just silence, and a gate that waits for the next fool to cross. If you want the most intense, soul-grinding chapter breakdown of the Imperial Invasion, the kind that burns into your memory, you’re in the right place. #Tensura #Rimuru #LightNovel #Anime #Manga #ThatTimeIGotReincarnatedAsASlime #Volume13 #DungeonBattle #ImperialInvasion #FantasyBattle #isekai
