Rasa seemed to realize something and spoke in a flustered rage.
Uchiha Yin was right. Sunagakure's Sealing Jutsu really was that weak.
And that sealing scroll had not originally belonged to Sunagakure. A mysterious stranger had given it to Rasa.
Rasa's face darkened slightly as he recalled the day that stranger had handed them such an incredibly valuable Sealing Jutsu.

Wasn't this the greatest possible blow to Uchiha Yin?
