Quylla emitted a shrill sound through her closed mouth as her skin turned black from the impurities that tainted it after reaching the surface. The same happened to her hair which lost its shades and to her nails which grew unnaturally long.
Then, they both fell off, just to regrow so quickly that the process hurt no less than losing them. At the same time, her skin dried and cracked due to the layer of external impurities having exceeded what the blood flow could sustain.
The black layer around Quylla fell apart, revealing the muscles underneath that twisted like living snakes entangled together. They also were filled with impurities from the harsh training she had endured and were eager to get rid of them.
The process happened three times as Quylla reached the deep cyan, then the light cyan, and finally the bright cyan core. Each time she would expel the same amount of impurities but the process would become more painful since they came from a deeper part of her.
