Finishing the transference, Mito died, at the end, it should be impossible to survive the extraction of a Bijuu, it fries all of your chakra channels, so its an instant death, some Uzumaki can resist for some time, but not Mito right now, she is old and was already at the end of her vitality.
If she was some 50 years younger she could've survived for some time, but sadly life isn't all flowers.
I guarded Kushina till she waked up, all this time I was observing the changes on her chakra, how it expanded and grew in density, the Kyuubi is really a boost in the quantity of chakra, if she continues to expand so fast like this, I wouldn't be surprised if she overtook me, even with my years of advantage. but sadly that will never happen, she will receive this massive boost of chakra for some time, until she is able to withstand it. And when her body is costumed to his she will eventually slow down on this process.
And there is the side effect, as she is just augmenting her chakra on a brute force method, her control will go to shit, no question asked. That method where I smooth my beforehand coarse channels and center, followed by bloating it with my chakra making everything coarse again, is a way superior method. It may sound simple, but the way to do it requires an excellent chakra control, and the better you control, the better your results. As with better control, you can bloat more, or smooth more. Making this an exercise that up to your chakra, flow, and control in a cyclical way.
After Kushina stabilized, it didn't take much for her to wake up, looking at each other I can see that both of us don't want to talk much right now, we lost someone important in our lives so I just want to rest for a bit, and bury myself on Anbu work afterward. It at least helps me distract.
After some days of mourning, I hastily returned to my Anbu duties, I started with the simply bandit extermination, to blow off some steam and frustration, followed by some spy and assassination missions, I even helped usurp a daimyo of some small island.
After Mito's death I started focusing a little more on seals, I still want the [Flying Thunder God], it will make my life a f.u.c.kton easier, and maybe using its principles I can create a gateway portal through the continent to facilitate transportation.
My plans in the Land of Iron are doing great, their foundation is almost set, everything is going according to the plan there, it is almost suspicious how much smooth it is going. But I won't accelerate things, it is better to do it slow and steady than fast and erratic. At the end I don't age anymore, yes I stop again the moment I attained the [Sage Body], principally due to mine being a special version done through the technique, but the important thing is that with it, I don't need to concern myself with time anymore. About my body, I still grow normally, it is just I will reach my 'limit' and stop growing in size. At least by natural means, I don't know if I find a jutsu to enlarge bones or something, I would probably grow more if I have something like that.
