Them splitting and going in different directions wasn't what Blues was expecting, but he was expecting retaliation. So Blues was going to move too, a lot faster than one would think a guy like him could move, firing another couple of shots at Wu Kong.

Which is probably not a very good idea, focusing his attention on the demon instead of Daichi. That and Blues still hasn't got a good idea on how to deal with 'magic', the ice attack does hit.

And boy does it hurt. For Blues at least.
