I am trying to utilize this method but its quite hard as many places in my body is harmed in nine tails attacks. But in this last 2 years i wasn't able to do that. And it might take me 2 more years i think.
G: "Granted. About the ring you will get it instantly as soon as you wake up. You will need to learn about Byakugan yourself, but i don't think you will be able to use it until you reach Chakra level of minor genin. Now of you go."
