Now that the story has gone for a while, some 'initial' impression:
For a very simple-looking manhua, this is... a surprisingly good one. Good pace for the nature of the story, but the story's still mostly on building massive disposition right now and long-term storytelling quality (e.g. the end path of MC's cultivation, her sister's role in the story, master's fate, all the different factions, and how it will be tied in the future story) is yet to be proven... but this one seems hopeful. I don't think this is for those looking for fast-paced, conclusive, short story arcs.
