The whole story of North Korean artillery turning Seoul into a sea of fire was a phrase coined by a North Korean general few decades ago to threaten S Korean. And that's what it is, a verbal threat. N Korean army would be really idiotic to focus all their available artillery on Seoul and ignore all other military installations. During the Battle of Britain, Luftwaffe nearly broke RAF when they concentrated on bombing the RAF bases. But when Nazi switched their focus to bombing London, RAF had a chance to recover and eventually beat back Luftwaffe. And you can bet S Korean artillery units won't be sitting around when the balloon goes up.
