Unfortunately…
It seemed like Di Tou might be that insane person?
After running out of scrolls to practice calligraphy on and realizing that although there was a decent chunk of ground on the moonlit platform, it wouldn't last very long, Di Tou decided to try another option.
This was, of course, after trying to draw on the invisible moon chunks scattered all around, and finding that, unfortunately, he couldn't leave a mark.
At least, not a visible mark. He could still punch a hole into the moon chunks floating around, and the depression would still be there, it was just that like everything else, he couldn't see it with his eyes.
So after thinking long and hard… Di Tou decided to combine the two.
Alright, that wasn't really true either.
