Reshiram, Sabaku, come here and help us out! I've got a feeling that Zekrom and Z are above!

The area's going to cave in, and I don't think that we're going to be able to reinforce the ceilling enough to prevent a Zekrom and a Rhyperior from falling through. Instead, I'd recommend you run. Quickly - the way I came is safe, I can guarantee you that. The Reshiram and the Flygon are with us.
