So, this story seems somewhat fine in the early chapters, but it quickly spirals out of control later on. His Junior Sister is a straight up idiot even though she is someone who is reliving her previous life. It's like she learned nothing and is focused on growing stronger even though in doing so she is standing out so much that it is putting her entire sect and senior brother in danger. The MC spends a lot of his time trying to clean up her mess which in turn creates bigger messes. You'd think someone who lived an entire lifetime would have more sense.The system is like a signin system, but it requires him to do menial tasks. It's not too bad and the MC is somewhat okay, but he has some problems too.
