i am still confused. so is this season 4 or kind of spin off?
They are set in Chang'an, so it takes place shortly after s3 if I understand it correctly. They probably filmed more cases compared to what would fit in the 40 ep limit, and turned these two cases into a short drama instead.
Finally it will air! I was happy to see Rain lu as fl again, but after the wrap we basically got no info xD I am looking forward to see her and Jin Zi xuan.
That was a very dramatic episode, but it kind of worries me that they just threw in the newbies in there without any sort of structure of how to handle their work.
So this is a mini drama featuring one of the officers in the currently airing Strange tales of tang dynasty, around ep 26. Looking forward to see more of these people.
