Marlo thoroughly enjoyed a good fight. That did not, however, mean that he was ignorant of the situation for the rest. Earth was losing the battle badly, and regardless of how many battles he won individually, the war was continuously being lost.
The first few waves of robots were not a problem for him at all, though they were already fairly high above earth's average level. But the latest wave, while seemed perfect for him, was much too strong for everyone else. The robots reached a strength equivalent to the middle of the nascent realm. That was a huge problem, for the earth was ill-equipped to face such strong threats without technology.
With a mighty roar, he slammed down his ax, slicing a robot in two. That was the fourth robot he had killed in a short while, and he was the only one who had achieved any kills. Comparatively, each robot killed many human soldiers at each moment.
