Slurp! Oho~! You're really into The Battle Cats, I see. It's a bit hard for me to tell if 'Seongbang' you mentioned refers to a strategy for defending the castle, or if it's an abbreviation for a specific stage. As the saying goes, 'Asking about what you don't know is a momentary embarrassment, but not knowing is a lifelong shame.' If you could tell me a bit more, I'll give you a clear answer. Hmm!
