We were brought here even when we shouldn't have been and the ones who should be dealing with the problem suddenly 'vanished'; that is the sticking point.

But, we shouldn't get too many wrinkles over it. Just as we're trying to solve the issue of this world, we'll eventually stumble upon any hints we'll need to help us.

As long as we keep our eyes and ears open.

[ Simple (?) enough. Jing Yuan suspects there is some mild kind of foul play in regards to the vanishing of those people, but he also seems to think that in general, they'll be able to figure out what they need to solve it all. ]
