(yes Kabuto will still be his right hand in the future
oh also this is fanfic, not a what-if certain things or)
Orochimaru was at the gates of Konoha it took 6 hours going top speed without rest even water walking from the island to the mainland to improve his chakra reserves and control so when he was called to the counsel room he sat and relaxed as much as he could in the chair Chizuki was still resting in an extra chair in one of the corners "while I did call you here you could've left the girl to rest better" Hiruzen said giving his student a deadpanned look the sannin just shrugged "so why am I here again? if it's about the secrets of Uzushiogakure, sorry but I can't tell anything" He confessed the 2 elders were about to run their mouths but he cut them from saying a thing "besides its right that it be told to Kushina more than anyone here it is her clan I'm sure you clan heads know that right?" he said smirking as he saw the look that flashed on Danzo's face before it quickly disappeared.
"Makes sense but what can you give?" Hiruzen asked Orochimaru put his hand in his pouch pulling out a scroll and tossing it to Hiruzen as the thing unraveled it showed a sealing formula "this is a seal used by the Uzumaki that if placed at the center of the village will repel any external threats by the kage activating the jutsu it's like a spiritual from than physical technique in that regard" he explained everyone was shocked "this will help a lot but do tell how you met this young Uzumaki" Hiruzen asked Orochimaru then explained that whole encounter.
"To think the Sand could do such a method but then again it's expected for things like that to occur in warfare" Danzo voiced 'if I had a weapon like that and massed produced it Konoha wouldn't need to lift a finger to take down our enemies' he thought. "Well, then Orochimaru your dismissed report back when she's up to continue we have other matters to discuss" Hiruzen ordered Orochimaru got up leaving taking his unconscious "companion" with him.
(sorry bout the delay anyways next will be Orochimaru getting Kabuto and having Chizuki for a purpose that will be realized later he'll be leaving Konoha after the nine-tails attack for reasons anyway comment suggest and peace)
