It's not necessarily a sequel but it's good to watch this part to understand the whole series because in my opinion they are not very related these parts are made in a way independent only that they have the same characters (not actors)

the mystic nine is about original nine families and how whatever happened before led to what wu xie and zhang qiling had to deal with now.

It is part of the same universe with the same characters involved in the show. It also happens right after the events or at least it's suppose to happen right after. We won't know for sure until it is finally released.
