Review Detail of Gratiz_ in Naruto: Time Traveler

It's a good fanfic, but let's get real, mc doesn't have time powers, he has the limited ability of transfering his consciousness to his previous self and somehow each use uses up all his spiritual energy (for example he wanted to return 1 hour to the past). This is annoying, because you can do so much with time powers: stop, slow barier (jjk six eyes), gravity (because gravity is a combination of space and time), recovery, bring back from the dead, time paradox explosions (delete button) and etc, the imagination is the limit..
