We reached the great wall, it appeared impenetrable. It was the mason's turn to step up. He had promised to get us passed this obstacle. Did he know some weakness invisible to our eyes? Some trick of the trade passed from generations? He called to his men and the cloaked giant stepped forward. We had all noticed him during the journey, but surely he did not plan to apply brute force. There was no one strong enough to even take the smallest dent in the great edifice. But when the cloak was removed, we saw this was no mortal. The gleaming red blocks must have weighed several tons. The entity stepped to the wall and lifted one great block limb, He delivered a hammering blow of amazing force. A shock traveled through the ground beneath our feet. Yet there appeared no damage to the great wall! Undeterred, the great stone limb rose again. Thus commenced an untiring, methodical, pounding. Each time the stone fist made contact at the exact same point. A small crack developed. Once the crack opened up, progress accelerated and we were through.
