One sunny morning, a lost man appeared at the door of a cave, leisurely eating grass on the ground. Suddenly, a young man with long hair and vigorous figure came out of the cave, which filled people with the idea of a full meal. A hungry tiger jumped at the food and headed for the elk, but the lost man reacted quickly, long before the young man landed. A hard push on the hind leg has made the body jump out of several places. Look at the fat in your mouth and leave him. Just then, another figure flashed out of the hole and an old man came out. His weak body and slow movements seemed unable to change the present reality, but at this critical moment, a miracle happened. The old man tried his best to throw out the stone in his hand. The stone moved forward quickly and hit the elk's head impartially.
