And only plot can stop her.
The facts that Byakugo works by accelerating cell division and that the cell division shortens a person's lifespan are confirmed, so let's throw that alongside a few more facts. Chakra is a necessity to heal wounds with Byakugo, so the logical assumption here is that Byakugo's mitosis is facilitated through the chakra system, which branches off into contact with every cell.
Sakura can forcefully give others chakra, AND control the chakra throughout them to perform instant mitosis dozens of times over with the end result of an enemy's body becoming that of a Shemadara's, a bulbous ball of literal cancer. Even more, she can make someone's heart implode with the speed of her mitosis.
Don't believe Sakura could efficiently hijack the chakra streams of others? Well, she's a genjutsu type capable of breaking genjutsu that even a perfect jin can't, and genjutsu literally deals with commanding control over the chakra streams of one's self and others.
Thank you and Sakura soloes.
