Eternals establishes in the movie that most of the tools and weapons that we use today, that we have been using since ancient times have been a gift or more appropriately a method of evolution from the Eternals. So it makes us wonder, are Shang Chi's rings too made by the Eternals?
In the Eternals movie a limitless new technology is established in the Marvel Cinematic Universe, as the heroes use ring-based technique which almost looks magical to behold.
But this is just incredibly advanced cosmic technology given to the team by the Celestial Arishem. Although fans now know that Arishem's plan is much more insidious than the heroes think.
Speculations and fan theories suggest that the titular Ten Rings were actually made by the Eternals before Wenwu found them thousands of years ago. Eternal Phastos creates a number of rings towards the end of the film to help the team join together and form the "Uni-Mind" so they can stop Tiamut the Celestial from destroying the planet.
The bands themselves look incredibly similar to the ones worn by Wenwu and Shang-Chi, which implies it's entirely possible Phastos could've created the original Ten Rings thousands of years ago as other weapons for the Eternals.
Eternals establishes that Phastos has a hand in the technological advancement of humanity because he can create any device or machinery that he thinks up. He had been working on the Uni-Mind for thousands of years, so the Ten Rings would have easily been prototypes. And, not to point out the obvious, but there are 10 Eternals in the movie and 10 rings — seems to be an obvious connection there. Consider also the "Shang-Chi" post-credits scene, where Wong tells our protagonist that the rings are emitting some kind of unknown signal to call someone — or something — out in the universe. If they are indeed Eternals technology, then they might be signalling other Eternals like a beacon.
