Naruto: Invincible from the Time He Beat Tsunade for Crying

While other people traveled through time, I couldn't even make a shadow clone when I traveled through it, and I had to hide from Tsunade's big feet. The system finally woke up and gave me a powerful magical power? Okay, since one punch can destroy the training ground, then I have to walk sideways in this ninja world! Tsunade, don't run away, listen to my explanation!
