Swallowed Star: Showdown on Primeval Star

Luo Feng is training on a planet that wants to kill him, surrounded by alien civilizations that also want to kill him. Pretty standard Tuesday for this guy. This ONA picks up with Luo Feng deep in the Primordial Star, a brutal testing ground where he's pushing past his limits — and catching the wrong kind of attention. The Demon Race, the Mechanical Race, and the Insect Race all look at this human getting stronger and collectively decide he needs to go. So they form an alliance, which is never a good sign for the protagonist but always a good sign for the audience. The early stretch is all about Luo Feng navigating hostile terrain and hostile aliens with a combination of martial arts, futuristic combat techniques, and a battle blade he's pretty attached to. Sparkly Key Animation Studio handles the visuals, and the CGI work on the alien environments and fight choreography is genuinely impressive — there's a weight to the action that a lot of donghua struggle with. The power system blends sci-fi tech with martial arts in a way that keeps fights unpredictable rather than just "bigger energy blast wins." If you liked Swallowed Star (this is set in the same universe, adapted from the same web novel), you already know the deal. If you're into stuff like The Wandering Earth's blend of humanity-vs-cosmos stakes with Chinese sci-fi worldbuilding, this hits a similar nerve but with way more hand-to-hand combat. Worth keeping on your radar for 2026.
