Review Detail of DaoistSoulTurtle in Transmigration with QQ farm

The story is good. We follow our main character as she uses her farming space to help her family. I feel the cultivation system is under-explained and underdeveloped. It would be nice if it was explored in a little more detail like is it just an accumulation of power, or are they opening meridians or maybe forming a core? Is there a doa or other driving force like heavenly laws? It doesn't need to be like anything I have described here but I think it is worth expanding on.
