16th Century: The world goes mad.
Impossible with sedentary agricultural civilizations. There are simply too many of them to wipe out entirely; they would simply become slightly different looking Chinese, but not wiped out. And I beg to differ in the first place, because a wide open continent, with the people literally falling dead at your feet conveniently opening up huge tracts of land, most of it exceptionally fertile... Well, it wouldn't be that bad. Especially since they'd be on the gold-bearing side of the New World...
