The Underworld River churned as if it were moving along with the vortex in the void. Only when the dark sect cultivator disappeared into the underworld planet and the even more shocking figure in the sky moved further and further away did the vast underworld river slowly recover.
Gradually, the river stopped churning. Gradually, the countless souls that had been trembling in the river returned to the surface of the river again and again. After a long while, the sound of souls could be heard again.
The sound of souls contained seven emotions and six desires, the desire to live, and the unwillingness to die. This was the normal state of the Underworld River, and it was exactly the same as before the Underworld sect cultivators went in.
To a certain extent, the Underworld River could also be described as calm.
