I spent roughly ten minutes at full speed to find a safe place to begin eating my spoils.
Although the head was gone, the body of the beast was quite large. It would take me far too long to ingest the entire thing, so I decided It would be time to test out one of my theories. With that I turned my body into that of a massive slime using [Metamorphosis]. I wrapped the entire body of the Giant King in a layer of my body to absorb the materials. The body was unreasonably large to begin with, and it would have taken hours to eat normally, but this way proved perfect for experimentation.
