Working in this manner, Di Tou once again cleared out a large patch of crystals on this side of the river, but after working for a while, he turned over the vial only to find… "Eh? I'm out of dissolving fluid." Tipping over the vial once more, turning it all the way upside down this time, Di Tou lightly shook and found there was not a single drop left. Scratching his head, Di Tou threw the vial into his Spatial Ring before turning around and looking at the small field of crystals on the floor and the somewhat long walk back to where he had entered the underground river.
