Yes flashbangs do extend shadows, but in order to, flashbangs momentarily break them , in order to extend them. When it was momentarily broken, thats when I escape, because of my rank, I'm faster than you think. Just yo let you know for future references, if you perform those handseals, your shadow breaks, because you aren't concentrating on the shadow. But I'll continue...
As I closed my eyes, when the flashbang went off, I open my eyes to see a huge wall in front of me. I then catch chakra traces of 3 different persons. So I quickly go digging underground, and come up on long range. I then see you coming with your flame rasengan, and your clones, so I do one handseal and create a small antilion right beneath you and your clones.
