"Unfeeling…" (非情に…, Hijō ni…) is chapter 343 of the original Naruto manga.
Sasuke sits upon a field of battle, having defeated hundreds of opponents. Orochimaru observes that he didn't kill any of them, to which Sasuke replies Itachi is the only one he wants to kill. In Konoha, Team 7 visits the Ramen Ichiraku. Naruto, having hurt his arm from using the Rasenshuriken, cannot eat by himself. He tries to get Sakura to help him, but is disappointed to receive help from Sai instead. He is even more disappointed when Kakashi takes over for Sai. Meanwhile, Orochimaru's body starts to reject him. When Kabuto leaves his side to get some medicine, Sasuke attacks him, remarking that he is willing to kill Orochimaru too.
