The dreadful cries and the angry swears of the prisoners could be heard in the Fiend Prison. It was unclear how many cells had suddenly become smaller and how many prisoners inside them were compressed into meat pies as a result.
The dreadful cries and the angry swears grew closer as the distance between heaven and earth narrowed; and then the cries and swears sounded distant again, not because heaven and earth separated again, but because the tipped over cliff and the rising pond bottom were fused together to form a closed space made of rocks.
Heaven and earth were compressed closer and closer, and all the objects were squashed as a result. The rocks were squeezed so much that they became incredibly hard, leaving no crevice between them.
It was quite difficult for the Underworld Emperor to break through the space in his current state.
