 After the villains leave, the nephews learn about an even older claim supposedly made by an ancient civilization (which they theorize to be the Phoenicians).Meanwhile, in a Brutopian hotel, Blue and Sharky are waiting until they have letters from enough descendants of the Chinese explorer to be allowed to rule America in their names.Upon learning from the newspapers about our heroes' discovery, which led them back to the Library of Alexandria (see Guardians of the Lost Library for details), Blue and Sharky went to a desert land where, on the remains of an old Native American ship, our heroes have found a stone tablet containing a claim that predates, and thus nullifies, their other ones.
