The large animals we rode moved quickly across the land. I could tell from the surrounding mountains that we were on the bottom of a long dead sea. In time we came to a huge city. At first I thought the city was empty. The buildings all were empty and in poor repair. But soon I saw hundreds of the green warriors. I also saw green women and children. I soon learned about many cities like this. The cities were built hundreds of years ago by a people that no longer existed. The green Martians used the cities. They moved from one empty city to another, never stopping for more than a day or two. We got down from our animals and walked into a large building. We entered a room that was filled with fierce green warriors. It was not difficult to tell that these were the leaders of the green Martians. One of them took hold of my arm. He shook me and lifted me off the ground. He laughed when he did so. I was to learn that green Martians only laugh at the pain or suffering of others. This huge warrior threw me to the ground and then took hold of my arm again to pick me up. I did the only thing I could do. I hit him with my closed fist as hard as I could. The green warrior fell to the floor and did not move. The others in the room grew silent. I had knocked down one of their warriors with only my hand.
