Unknown Fragment no: 120804's activites

Hello!! I'm here to ask for a favor/help about the story of Nano machine and Myst, might and mayhem, etc series.
I've seen some posts regarding about multiple stories that's connected to it and I'm starting to get interested in the murim genre so is there a particular order I should read, and if I were to read it randomly would it work just fine or would it make the series significantly better if I know the other series first?
