Ling Cage (Seasons 1–2)

Ling Cage (灵笼, 2019) is a Chinese post-apocalyptic donghua you can watch online — bleak 3D-animated science fiction directed by Dong Xiangbo. After the Moon slips its orbit, decades of catastrophic earthquakes nearly wipe out humanity, and the handful of survivors huddle inside a suspended city floating above a ruined Earth.

The surface now belongs to hostile new lifeforms, so what's left of mankind clings to a hovering platform governed by harsh rules: your worth is your usefulness, and the hierarchy is brutal. Scouting squads still drop down to scavenge, and every descent might be their last. The show blends action, mystery and a hard-edged drama about what a society becomes when the urge to dominate is baked into its blood, even as the world it ruled is mostly gone.

Produced by Soya, it stands as one of the most ambitious Chinese animated series of its moment: heavy atmosphere, a carefully built setting, grown-up themes. It suits anyone who liked the grim survival mood of Attack on Titan or sci-fi about the last scraps of civilization. Stream Ling Cage (2019) online on iFILM.
