To possess the Heavenly Body

After getting grievously wounded from a hard battle with an old foe, the Celestial Emperor sealed himself in the core of a far-flung planet for rehabilitation.
The spiritual power he released gradually transformed this planet into a habitable place for all living beings.
By cultivation, the original dwellers developed their human-shapes, and created their own civilization.
Years later, human beings from the Milky Way Galaxy flew here on space ship.
This planet started to draw the eyes of unknown forces from different spheres.
Amid conflicts rose heroes.
And Xia Guixuan, well seated in the core, opened his eyes.
