"So to sum up, we can deduce that the location where Mary's treasures were hidden must meet the following criteria," Joan concluded after discussing with Leonard Ethan for a while.
"Firstly, the space of the Treasure Location must be large, at least big enough to hide treasures that would fill two carriages, because the probability of exposure when hiding everything together is much greater than when hiding them separately."
"That's correct," Leonard nodded in appreciation, because the chance of being discovered is very high if the treasures are hidden separately. And once a single item is found, the diggers would realize there's a Treasure Hideout and commence targeted excavation.
Frankly, the essence of hiding treasures is to keep people from realizing there are valuables at the location; otherwise, no matter how well concealed or how many traps surround it, nothing can stop those greedy treasure hunters.
