I Mastered Cultivation, Only to Start Over

In my previous life, I worked hard and lived to be over a hundred. I never let go of the family martial arts, supposedly meant to protect some strange things. But those things never appeared before I died, and the family art was never passed down either, since I was alone until the end. When I opened my eyes again, I never expected to find myself back in elementary school. But the things I'd trained into my bones... I have to say, they're really something.
