Thread for clues or theories anyone has. Here's an image I found on the official weibo account.
According to this map, there are 4 levels in the assassin ranking. We know now from the 3 episodes that came out that Shangguan Qian went from chi to mei and Yun Wei Shan went from mei to chi (this was revealed in ep 3). We also know that Han Ya Si and Han Ya Qi are their "ravens" and according to this ranking system, Han Ya Si who is Ayun's raven is at a higher level than SGQ's raven. They are a part of the "raven system?" we don't exactly know what that is yet.
We know that Ayun's mission is to marry the sword wielder and SGQ's mission is to marry Gong Shang Jue. We also know that Gong Huan Yu and Gong Hong Yu died under mysterious circumstances but that poison was involved. Ming Wu Ji who is the concubine, was at the scene of the crime but did not see what occurred because she stepped out of the room and the other excuses that she gave. The guards backed up her story.
Lastly, the Wufeng sect leader did not order Gong Huan Yu and Gong Hong Yu to be killed so right now they are confused about what's happening as well. Finally, in a month's time, someone will come to get information from Ayun and SGQ. If it's useful they will get a "cure" for the flies inside of them. Activation of the flies is not something any assassin can bear and is used to keep them in line/loyal.
I'm missing some stuff but that's what I have so far.
