City Lord Manor.
There was a dark corner in the northwest corner of the City Lord Manor.
This corner was dark all year round and nothing could be seen clearly. Anyone who was familiar with this place would know that there was a staircase leading down from the deepest part of the dark corridor.
There were hundreds of stairs spiraling down. Standing at the top of the stairs and opening the door engraved with array runes, one could hear countless miserable shouts echoing in this space.
This was the underground water prison. The water prison was in the shape of a pillar and was under the City Lord Manor.
It was more than a few thousand meters deep and more than a hundred meters in diameter.
On both sides of the huge cylinder, prisons were dug out. The dark underground below the abyss was still filled with dense moisture.
