Youku Animation also previewed a longer PV for An He Zhuan (Legend of Assassins) but also no air date. A new poster is also revealed featuring Su Muyu and Bai Hehuai.
I'll share the PV video here until Youku uploads on YouTube.
The trailer goes through a few sequences, but the main ones are:
0:00 - Su Muyu fights Mu Yinzhe and his puppets in the forest
0:22 - 0:28 - Blink and you'll miss Su Changhe's face
0:29 - Su Muyu fights Su Changhe
0:30 - Patriarch against Tang Second Grandmaster (was also in previous PV)
0:40 - Bai Hehuai and Su Muyu (dunno who's the man in the mask)
0:54 - Su Muyu's Kui mask
I just realised Mu Yinzhe (慕尹折) is not Mu Zizhe (慕子蛰), whom I mistook him for last time. I think this character is not named in the book, but this scene does take place.
