Orochimaru was against the coast with a force of 2,000 the reason for the force is simple unless it was a full-blown invasion divisions with S-rank shinobi are given troops of 5,000 for an initial strike while 6,000 stand back just in case. but on the other side was a force of 10,000. "oh great it seems like I'm about to meet the fate of the raikage" he clicked his earpiece "Tsunade could you assist me it seems we were miss informed it's a force of 10,000, not 6" there was static until she answered back"you will have to keep them for 8 minutes don't die" orochimaru sighed before smiling ' well I'm glad I'm Orochimaru escaping death is the trait I have now' he smirked before his chakra exploded with power going into sage mode "I'm about to commit a ton of war crimes with the way I'll make this battlefield look!" he shouted releasing a wave of killing intent while he did scare the shinobi due to how they were trained most put themselves through pain before continuing their advance.
Seeing the all charging in his direction he smiled as he rushed in at blinding speeds he punched one guy's head flipped in the air grabbed another dude's neck crushing it knocking 4 people aside he then used it as a body shield blocking a hail of senbon landing on another person breaking their spine as blood spat from his mouth Orochimaru touched the using inorganic animation as the ground exploded in a rapid wave of spikes killing hundred he blitzed seeing a member of the Kaguya clan punching her in the gut knocking her out "your genes will be so useful for the perfect body I plan on making he unwrapped a scroll sealing her before dispersing into snakes appearing back at his starting position his arms outstretched " so do you people still want to charge to your deaths or will you give up or do you want me to put the kid's gloves back on?" he asked mockingly then Tsunade jumped down beside me "it isn't really good to piss them off in the middle of a battle" she said he Ignored it turning to the readied troops and decided to give a speech "Listen I lightened the load for you so give them hell show them the superiority of Konoha!" when he finished they all cheered turning around "now then let's win this!".
The Mist and Leaf clash with the 2 sannin were clearing a path bodies flying it went for a hour until the most left with a force of 2,300 and Konoha had a force of 1,600 the battle would drive Kiri to do something desperate.
(yes this was build up and yes he did steal more than just some random kaguya but those bloodlines won't be revealed next is Kiri's move on run but it will be stopped by our scheming MC especially since Obito will be there it'll be a big change peace)
