-boat sails North for ~13 days, sees first ice chunk.
-boat sails North for 4 days, gets sacked by iceberg.
-iceberg drifts North for 8 days, daylight gets longer. Xie Xun attacks Yin Susu, saved by aurora borealis (very uncommon in China, says narrator, suggesting they're north of China already).
-iceberg drifts North for ~4 days, Xie Xun attacks Yin Susu again, gets blinded by her needles.
-they lose track of days. One day, they land on Ice Fire Island.
Before they lost track of time, they were 30 days into the journey. For the remaining time, JY made no suggestion that it was a long time. Specifically, he says they traveled for a total of "several tens of days" (两人在大海中飘浮了数十日), So let's say 35-40 days total.
... of which only 1 day was east-bound, the other 30+ being northbound. Keep in mind they sailed from Hangzhou / Lin'an. Now, based on the direction we're told, they should have ended up around the border of Liaoning and North Korea. Obviously, given the ubiquitousness of icebergs and the comments about aurora, I think JY intended the destination to be farther north. Keep in mind when they left Hangzhou, it was warm weather, since they were wearing little clothing (and got cold as they sailed north), and the long daylight further confirms it should be summer time. For there to be ample icebergs in the summer, I think they were very, very north.
