Chapter 70: Uzumaki Clan's History
Naruto and Karin spent more than two months in "Whirlpool Village" before they managed to make rubbings of all the inscriptions, big and small, throughout the village.
During this period, they received a few letters from Jiraiya intermittently.
Some were requests for him to return to the Land of Fire.
Others invited him to attend the ceremony for Hatake Kakashi's inauguration as the Fifth Hokage.
There were also some miscellaneous matters.
Naruto declined most of these requests.
The only exception was when Kakashi succeeded as the Fifth Hokage; Naruto sent a shadow clone to offer his congratulations, but his true body remained in the Land of Whirlpools, studying the inscriptions.
Most of the valuable items had already been taken by other ninja villages.
What remained were mostly "myths" and "history."
