Shinno's expression changed drastically. When had he exposed a flaw?
Sakura was already standing beside Naruto, helping Amaru to her feet.
"Naruto, don't joke around with an old man like me." Shinno tried to explain himself.
"What are you doing, Naruto? What are you going to do to Teacher Shinno?" Amaru tried to rush over, but Sakura grabbed her and held her back.
Sakura shook her head at her. "Calm down. Listen to what Naruto has to say!"
Naruto looked at Shinno with a serious expression. "During the Second Shinobi World War, a Sky Ninja stole a forbidden technique called the Tailed Beast Sorcerer from the Scroll of Seals. Before that, he had disguised himself as a doctor and stayed in Konoha."
"Guy-sensei's father, Might Duy, was treated by you. Shinno, the older generation in Konoha all knew about this. Even though it was a long time ago, a little investigation would still uncover it! If I'm not mistaken, the ruins nearby are the hidden base of your Land of Sky, right?"
Shinno shook his head in disappointment. "Sigh, I had wanted to keep pretending, but I didn't expect this. Fine, you're right, Naruto. But my goal has been achieved. The Dark Chakra Zero-Tails needs is already sufficient."
"Zero-Tails? What is that?" Sakura had heard information about the nine Tailed Beasts, but this was her first time hearing of Zero-Tails.

Shinno revealed his true face and said mockingly, "Naruto, your Senjutsu is indeed stronger than I imagined, but you cannot withstand the darkness
