Is that GROUP WASTING THEIR TIME; IF THER IS TREASURE OF WHAT KIND?

From my research added on to the shows', I would say yes. A certain book describes that the Knights Templar had voyaged over to Nova Scotia to hide treasure, documents, magical items etc but the ultimate treasure it said was at least a mile or so down and all the other treasures above it are distractions. The item is described to be the red crystals that destroyed Atlantis and are Tesla like power source

What book?
Please elaborate?
Thanks!
