I hope Li Miaomiao will not stay as a flower vase, a decorations that only here in the beginning of the novel and will be irrelevant in the future of the story... we need a power up for herᕙ[・・]ᕗ
I doubt she will have a power up on martial arts. Probably she will continue supporting (emotionally and rationally) the mc, like now. She can be a super-star streamer/artist too on the future, but nothing much different from now, considering the mc's progress.
