I always read story about Boruto returning to the past but what would happen if 7th Hokage, famous Naruto Uzumaki, go to the past?

Sarada, Boruto, and Mitsuki had a very important mission but when a scroll was opened by someone the young ninjas meets the younger team 7. They need to help the next generation get back before it's too late. [Ignore some spelling errors, and fixing the story]
