He became Juubi Jinchuriki to survive that. is this going to be one of those "who needed a more OP technique to survive this" discussions?

Wind Style itself cost years, Wind Style Rasengan cost years. He had a couple of hundred clones at all times, making every training day about equivalent to a year. Of nonstop training, so equal to several years of regular ninja life
