Sai was monitoring Kibaku Kido.
More precisely, he was tracking Shimura Danzō's movements.
They knew by now.
Their research base was in a secret valley deep within the Land of Frost.
The Land of Frost.
It lay between the Land of Fire, the Land of Hot Water, and the Land of Lightning.

Under normal circumstances.
To travel from Konoha to Kumogakure, one had to pass through the Land of Hot Water and the Land of Frost.
And vice versa.
This country was covered in frost all year round.
It looked like a white and gray country.
What fell from the sky was not snow, but frost.
Kibaku Kido often acted together with Majiye.
A large number of sensory barriers had been arranged around the secret base in the valley, making it impossible to approach easily.
Although forcing their way in would not be difficult.
The other side already knew that they were investigating.
To startle the snake would only make the other side mobilize everyone, or even destroy the base and flee.

They had arranged to meet again today.
