Drums creep along the battlements as a red eclipse bleeds over the Hexi Corridor. A fissure yawns beneath the watchtowers—the Tao Tei return, leaner and hive‑smart, led by a Stone‑Singer whose call travels through the Wall itself .

Garin (Damon) rides back with a stolen compass that points to sound , while General Lin (Jing Tian) fields new Crane and Eagle corps forged for daylight and smoke . Ballard (Dafoe) resurfaces with a map you can only read at sunset .

Set pieces snap: a cliff‑bridge sprint above needle spires, a mirror‑tower sunburst that blinds the swarm, and a zero‑light tunnel where steps must match the drumbeat—or wake the hive . Final image: glyphs ripple across brick as the Wall begins to sing. “Hold… or be hollow.”
