Sasuke did remember Itachi mentioning that when he was young. So the Third Hokage had been behind it all!
At that thought, he turned to the Third Hokage and slowly drew the Kusanagi Sword.
The Third Hokage, in his Impure World Reincarnation state, looked calmly back at Sasuke without saying a word.
At this point, the Third Hokage had no intention of explaining himself. He had been brought back for so long that he had come to terms with everything. He was a puppet Naruto could control at will. He wanted to break free, but he could not.
He had even learned to bear the grief of knowing that the body he now occupied was Asuma's.
As for the things he had done while alive, those were the deeds of the man he had been as Hokage. What did they have to do with the dead Hiruzen Sarutobi?
Seeing the Third Hokage's calm face, Naruto assumed he had nerves of steel and skin to match. He had no idea what the man was actually thinking. Otherwise, he would have praised him:
You really are something, Zhou Shuren!
Naruto looked back at Sasuke and continued, "Later, Shisui Uchiha awakened the Mangekyō Sharingan and foolishly told the Third Hokage, whom he trusted completely. Not long after, Danzo gouged out his right eye."
"I don't know what Shisui Uchiha was thinking then, but he decided to throw himself into a river. Before he died, he helped Itachi awaken the Mangekyō Sharingan and gave him his left eye."
"After that, Itachi still trusted the Third Hokage completely. He joined the Anbu and became a double agent for the Uchiha Clan and Konoha."
A thought suddenly struck Naruto. *Damn it, did Itachi get hit with Danzo's or Shisui's Kotoamatsukami? How else could he do something
