However, Huang Yi, bathed in endless attacks, remained unscathed, without even a change in expression.
After completely mastering Heroes' Prison, he was in an invincible state within it, and only brute force breaking through Heroes' Prison could harm him.
"Retreat!" Seeing the situation, Gui Tianzhu, uninterested in fighting, immediately ordered a retreat.
All the Naga experts rushed towards the Dragon Mouth like lightning, trying to leave the dangerous Heroes' Prison as soon as possible.
But soon, their bodies stopped, and no matter how hard they tried, they couldn't get out, as if an invisible barrier was blocking them.
"Did you think that Heroes' Prison is a place you can come and go as you wish?" Huang Yi folded his arms and looked at them.
The Nagas were immediately flustered, the way the Heavenly Demon died was still vivid in their minds, and they were afraid they would soon suffer the same catastrophic fate!
