Yu Chen was eighteen years old and was born with wings, but for the fourth time he could not fly at the Yunmen coming of age ceremony. On the day he was sentenced to ground service and almost lost the qualification to practice wind arts, the wind tower echoed, and a metal box engraved with his father's old seal appeared from the old wind duct ten years ago. The broken page in the box points to Yu Cang, who has been missing for ten years, and also points to an old case that was deliberately deleted: Yu Cang once stole forbidden objects, cut off the main wind path, and caused three deaths and eleven serious injuries. In order to find out what his father had done, Yu Chen left Yu Republic of China and entered Qingqiu, Leize and Nanhuang successively. Amidst ecological disasters, ethnic conflicts and human manipulation, he discovered that the same Jiuli black iron technology was rewriting the wind, fog, thunder and fire of the wilderness. In the end, when Jiu Li leads Chi Ying to use the "Wind Suppressing Nail Formation" to make the entire Yu nation fall from the sky, Yu Chen must give up his obsession of "solving everything alone" and work with Su Jiu, Lei Ming, A Li, and Yu Ling to reverse the eye of the storm, and refuse to simply rewrite his father from "traitor" to "hero" after victory.
