As David contemplated his plan, he made his way back to the fantasy world, utilizing the calculated time difference to his advantage. Returning to the exact location where he had left, he observed that mere minutes had passed on Earth, while several hours had elapsed in the fantasy world.
Timing was crucial, and he had managed to arrive just before the dungeon crumbled and disappeared, signaling the completion of his quest.
"Boom"
Exiting the dungeon, a resounding boom reverberated through the air as the structure collapsed and vanished, erasing any trace of its existence. Security personnel, in awe of David's solitary victory, rushed towards him, expressing their admiration and concern.
"Are you alright, sir? Did you slay the monster?" one of the security personnel asked, their eyes filled with admiration. David responded with a confident smile and affirmed their assumptions.
