Back in the elemental Nations
News has spread like wildfire of Naruto escaping The blood prison and destroying the box of bliss and killing the demon inside but instead of going back to the hidden leaf he went rogue in their eyes many of the Nations put out a bounty on him or any information of him and his friends he made in prison but no news of the such came the alliance moved forward and after one year they found out that the statue that held all the tailed beasts was destroyed and they had no idea where they went after that they went forward with their plans and had the fourth great ninja war with the rest of the Akatsuki they had won but the alliance is still on uneasy terms they had no idea where their tailed beasts were at or if they would reform after they killed the real leader of the Akatsuki named Obito Uchiha he had gave them a little information on their whereabouts that they left the elemental Nations with the nine tails and he couldn't get past the barrier to get them and he killed his source of information named zetsu and he couldn't control the army that he had under his control all he had was rogue Shinobi and undead Shinobi in his army afterwards they found out truth about what he said and it couldn't get past the barrier for what they were able to figure out from whatever seal Masters they had left that the barrier would come down in 10 years maybe if 6 if they are lucky. Which actually they are not afterwards they did what they can and rebuild and prepared for the day the barrier goes down to find one Naruto uzumaki and their tail beasts.
