"SIR! Look at the dungeon's portal! It's... changing!"
"The orange hue has dissipated... it's green now!"
"But how? The portal should shift to red when a dungeon break is imminent, unless..."
"The final dungeon boss has been defeated... but that's i–impossible!"
Murmurs erupted outside the Slime Grime Dungeon. Multiple dungeon guards stared at the swirling green portal, weapons in hand, not daring to lower their guard. Their minds swirled with questions, until a group of battered youths emerged from within, their appearance sending shock through the gathered crowd.
"So the dungeon energy level didn't fluctuate... there really are survivors," one guard muttered, watching as more and more figures stumbled out.
As they kept coming, the murmurs grew louder. The number of survivors was far higher than expected.
"I don't get it... how's this possible?"
"The dungeon evolved to E-rank... and the entries were only F-rank... it doesn't make sense how they survived."
