What is a Golden Core? The Golden Core is a reactor.
As stated in the "Turing Danjing," swallowing a Golden Core means 'My life is controlled by me, not by heaven,' referring to the process of embedding the reactor into the body.
If Foundation Building cultivators rely on synthetic muscles and still maintain a human form, then at the Golden Core stage, they become truly "non-human."
The most prominent feature of cultivators at this stage is the increasing proportion of cybernetic components in their bodies, leading to a transformation.
The powerful energy provided by the reactor, combined with a jet propulsion system, gives Golden Core cultivators the ability to fly and burrow.
And their high-strength cybernetic bodies, equipped with gravity shields, allow them to be impervious to blades and bullets while unleashing their full power.
