Netherworld Sea prison.
It had been half a month since Yuchi slew the Three-headed Naga Siren. During this time, he did not encounter other ancient existences that were the slightest bit difficult.
Although he did fight a couple of ancient monsters, none of them were worth mentioning in comparison with the Three-headed Naga Siren.
The situation at the Netherworld Sea prison had stabilized.
Before that historic battle, Yuchi had cut off the anchors that held the Netherworld Sea prison island in place, which caused the entire island to float away.
If he had not done so, the battle would have affected the other prisoners on the island.
Although the glass on the windows of the prison building were broken, none of the prisoners were injured.
Overall, things were still okay.
It was the mental state of the prisoners that had suffered a serious shock.
