Interstellar Ancient Martial Arts Supreme

When I wake up, things are different and people are different. Interstellar, mecha, hover car... What happened to this world? A girl from the ancient martial arts family was reborn in the body of her brother's descendant a thousand years later. She learned that the ancient martial arts in this world had declined. People admired the power displayed by those metal products more and expected to obtain energy from the evolutionary fluid instead of practicing ancient martial arts on their own! Main elements: ancient weapons, mechas, and superpowers. Category: Rebirth. The relationship between the male and female protagonists: the female protagonist is self-reliant and self-reliant, the male protagonist protects her, and the female protagonist does not care about her! Story. O(´^｀)o
