Team 7 had just gotten back from the land of waves mission and were exhausted. That's why the smoke bomb caught them off guard. Orochimaru had just two days prior thought of an even better way to get the body he wanted. He was going to take Naruto and make him pregnant with Sasuke's baby then steal,raise,and take over the baby's body when they matured. He had invented a jutsu for just this purpose called linked life it's original function was in times of war when there were not enough Female to Male ratio. It worked by creating an artificial womb and merging the recipient's chakras it was also undetectable until a fetus had developed. As team 7 was blinded by the blast that's when Orochimaru initiated the jutsu by the time the smoke cleared all was going to plan and Orochimaru escaped unharmed. What was that Orochimaru trying this time he did not attack us and just distracted us and who let him in here Naruto was quick to ask. Surprisingly Sasuke was the one to answer probably Orochimaru disguised himself as someone else as usual. Let's report this to the Hokage said Sakura then we can all go get ramen this mention of ramen piqued Naruto's interest yeah let's go do that I'm starving. MMH said Sasuke and off they went on there way to the Hokage tower. About 10 minutes later they had arrived they were let in almost immediately. Sarutobi greeted team 7 with a big smile, how was the mission. So the next 30 minutes were spent talking about the mission, Orochimaru, and other such thing's. The Hokage's face was grim when the news of Orochimaru came up. This is unprecedented will have to keep tighter security from now on but you say he didn't try to attack you at all just distract you. Watch your backs I have a bad feeling about this.
