• Uchiha Yū reminded the White Snake Sage of their earlier agreement and warned that Ryūchi Cave could not extend its influence into the ninja world.

• Orochimaru activated the base’s underground chamber and showed Uchiha Yū and the Three Divine Princesses the black giant beasts he had bred for the war.

• Uchiha Yū spread Radiation Element through the air to weaken Katsuyu by cutting off its supply of life energy.
