In the middle of the white flame sea, Ace was running at full speed for an unknown time while experiencing excruciating pain, and his head was buzzing with voices.
He didn't know how much time had passed since he stepped in the Cinderfall of Doubt or how long it had been since he started to run, but the pain he was experiencing continued to grow.
At this moment, he felt as if his skin was melting and his insides were filled with burning lava; with each breath, he felt like he was inhaling pure fire, so he stopped breathing to lessen his pain.
However, it wasn't working, for that fire was directly burning his soul, and this was far worse and more painful than physically burning. Moreover, he had to actively focus so he wouldn't lose himself in those voices.
"Give up~"
"The pain will be over; give up~"
"Why are you still going? There's no end to this place; there is no hope. Give up!"
