Naruto Subbed Episode 91 - Inheritance: The Necklace of Death
Recognizing the danger the attack imposes, Tsunade forces it into the ground, where the minor damage it inflicts indicates that it is not yet complete. Despite this, Tsunade offers Naruto a proposition: if he can master the technique in one week, she’ll give him her necklace, something worth an immense amount of money. If he cannot, she gets all the money in his wallet. Naruto agrees to the bet, and leaves to start training.
