The Wind Blows in Changlin 琅琊榜之风起长林 has released posters for its supporting cast. No official synopsis has been released, but the one translated below does seem to align with the latest batch of character posters.
During the chaotic Northern and Southern Dynasties, the northern frontier of the Liang Dynasty is protected by the powerful Changlin Army led by Xiao Tingsheng (Sun Chun) and Xiao Pingzhang (Huang Xiaoming). During an expedition, Senior Grand Secretary Xun Baishui (Bi Yanjun) cuts off supplies to the front line, and Xiao Pingzhang is severely wounded. His younger brother Xiao Pingsheng (Liu Haoran) leaves Langya Hall in order to get to the bottom of the conspiracy.
It turns out that 30 years ago, neighbouring kingdom Yeqin was suffering from the plague, yet Liang kept its borders shut for self-protection. In order to take revenge for his fallen kingdom, Pu Yangying (Guo Jingfei) travels to Liang under a hidden identity, and colludes with top martial artist Marquis Mozi (Cheng Taishen) and Xun Baishui to weaken the Xiao Family’s power and poison the people of Liang.
Xiao Pingzhang dies from poison during the war, and a year later the Liang Emperor (Liu Jun) passes away from sickness. The Yu Dynasty takes the chance to invade, and Xun Baishui and Xuan Yuanqi the Prince of Laiyang (Wu Haochen) coaxes the new Emperor (Hu Xianxu) into releasing an edict banning the Changlin Army from going into battle.
Pictured at the top is Zhang Huiwen (Coming Home) as Lin Xi, physician from Jifeng Hall and love interest of Xiao Pingsheng. Co-stars include Li Jia (Tiger Mom) as mother of Prince Laiyang, Xing Minshan as Duan Tongzhou and Jin Zehao as Yue Yinchuan. The Wind Blows in Changlin is slated for 30 episodes and will commence filming on December 15th.
