After familiarizing herself with the Celestial Refining Sun Art, Lynne immediately put it into practice, causing her celestial body to pull in the surrounding sunlight like a black hole.
Lynne was covered in a powerful white brilliance in that instance, drastically increasing the temperature and melting everything around her.
However, this white brilliance only appears so to the human eye. In truth, the white brilliance comprised of all colors of the rainbow.
Nevertheless, as her celestial body devoured vast amounts of sunlight, they entered her skin and flowed into her celestial veins.
Then, the sunlight traversed through her celestial veins like they were caught in a powerful river current and circulated throughout her celestial body with increasing speed.
When the circulation speed reached a certain threshold, Lynne's celestial veins glowed with the brilliance of the rainbow—contrary to the pure white brilliance outside her celestial body.
