Youku Animation held their annual press conference today to announce all their upcoming programs. This includes, of course, Season 3 of Shao Nian Ge Xing - Immortal Mountain Beyond the Sea Arc (海外仙山篇). There's no other information besides a short PV which contains stills only.
The poster for the season was also revealed.
The first image below is not from the PV; it's the last image of the last episode of Season 2, which shows Penglai Island, the so-called "immortal island beyond the sea". The other two images are from the PV.
I'm surprised to see Hua Jin because in the novel, Xiao Se stated explicitly that he didn't want Hua Jin to accompany them on the trip because it was too dangerous. The second image with the line drawing of Mo Yi overlooking the island and ship is stunning.
Look forward to Season 3!
