Last chapter it mentioned that explosion sounds were coming from the valley they are at. And the report was from 4 days prior. And if you go back to chapter 54 when Goemon started fighting the Cardinal, we learn about it from a report as well so more time could have passed. Then you have all of the travel time which would be at least a couple days, maybe. So I'm thinking around a week at minimum.Anyone know how long they've been fighting?
