For something like some weighted door to exist in such a place was really not an ordinary thing, as this was mostly the plot for when important things were found, so Dustin didn't give up.
Using every ounce of strength he had left, Dustin applied the maximum amount of pressure he could on the door and pushed with everything he had, but in the end he had only managed to push it to open just the slightest bit more.
"The fuck? If it won't budge, then there's only one option." Victor said, as the only logical way he could get across came to him.
Starting with the bag around his waist, Dustin took it off and then his shoe, followed by another thing that was not part of his shirt or trouser, then he was ready. He stood before the door and after inhaling and exhaling couple times, he rubbed his hands together a bit, then approached the door. Taking in another small breath, Dustin sunk in his stomach and arched his shoulders before attempting to put his leg through the narrow opening.
