After leaving Nugget Bridge, Xia You continued west along the river. With his careful searching and the combined efforts of several Pokémon, he soon discovered a hidden, unnamed cave at a bend in the river.
Without hesitation, he led his three Pokémon straight inside.
Inside the cave, a dark path initially sloped downward. Only after walking several dozen meters did a faint light appear ahead.
