The reason Di Tou was deciding to set off once more was very simple. After practicing here for over a week, the grass in the local region had been shaved half bald by him! If one were to look down with an arial view, it would look like someone had carved a checkerboard out of the plains, as chunks of grass were taken out all around. Of course, if that was all, it wouldn't be so much trouble.
After all, even if Di Tou was very wasteful, as one person it wasn't easy to deplete the resources of a region, especially when it was simple things like branches and grass which could be found in great quantities as long as you were willing to walk a few hundred meters. The problem was, in the spots were Di Tou had been sweeping, the grass was starting to regrow with great vigor.
