The temple ...

[Flar]

...just read about the excavation of the temple. Heard that there is unbreakable granite stone all around the caves. And it is well closed, not to get easy in there. Maybe it is the other  way round: Something or someone should not get out there ... is shielded by a metal umbrella ... and doesn't like water at all... you should think about, before drilling to deep ...
