>You fly carefully into the tunnel, and invite the others to follow. It really does take some finesse to navigate in here, and the bottom edge of your dress ends up dipping into the water, anyway. Blasted gravity. Still, aside from that, and the occasional fleck of spray, you manage alright. The tunnel itself has a pronounced slope; Suika was clearly angling upward as she dug it. You soon reach the end of the part she created, and see the intersection with the river.
>The main flow of the river is coming from your right, where it quickly winds away from sight. The original path of the river continued to the left, but the flow there is very light, now; most of the water has diverted to the new tunnel, since its slope is much steeper.
