This gigantic corpse was the energy shell formed around the body of a Greater Power after death, also known as the strong warrior's coffin.
The true Greater Power lay at the center of the corpse.
If you encounter a corpse in the starry sky that is like a star, then it is such a strong warrior's coffin. These coffins only form in the Star Sea.
The Star Sea is dead, and the energy that disperses from it won't be absorbed by the world but rather naturally gathers around the body. If it were in the Three Thousand Great Worlds or the hundred thousand smaller worlds, the power of a strong warrior would be immediately absorbed by heaven and earth upon death, at most forming a forbidden area.
If anyone from the Sealed Emperor's Palace were present, they would immediately recognize these three as three ancient ancestors from the Sealed Emperor's Palace, from time immemorial.
