[After trying for days, Luffy has found that he is having a really hard time breaking through the barrier. He's barely eaten at all, which is very much unlike him]

.......

[He figured it was about time for him to go back now. He has tried nearly everything in his arsenal, but the barrier has failed to show any signs that it's taken even a lick of damage from them. Back home he was able to punch through stone, and even steel, but this barrier... it was unlike anything he has ever seen before. What the hell is this thing made of?!]

[Luffy thought about climbing down from the mountains, but he really didn't have the energy for it, so he thought of another idea. He inhaled a huge amount of air, causing his stomach to expand, and then proceeded to twist his body. He let out all out of the air onto the ground which caused him to go soaring into the air]

[He landed hard on the ground, which didn't really effect him since he's made of rubber. He got up from the ground and began to dust himself off a bit before putting his straw hat back on, which was lassoed around his neck via a string. People near the edge of town might have heard the boomey sound of him crashing]
