Here’s a concise plot recap of Mystic Nine (老九门, 2016) based on confirmed sources:
During the Republic of China era, the city of Changsha is guarded by nine powerful families—known as the Mystic Nine or the Old Nine Gates—who hold sway over tombs, trade, and burial routes.
In 1933, a mysterious “ghost train” derails at Changsha station, discovered to be carrying bodies of Japanese soldiers and clues tied to a secretive mine outside the city. Zhang Qishan (the leader of the Mystic Nine and a military commander), along with fortune-teller Qi Tiezui, begin investigating its origins.
They try to enlist the help of Er Yuehong—an opera singer from one of the nine clans and a tomb expert—though he’s preoccupied with caring for his terminally ill wife, Ya Tou. Zhang Qishan also seeks medicine in Beiping (Beijing) to help Ya Tou.
As they close in on the mine, they uncover that its mystery is connected to their own family histories and a Japanese plot to exploit the mine for sinister experiments and influence over Changsha. Political rivals and betrayals from within the Mystic Nine also compound the danger.
The story revolves around brotherhood, duty to one’s sept, and loyalty to country—forcing the Mystic Nine members to risk everything and confront both supernatural traps and human villains to protect their home and uncover a century-old conspiracy.
