Isabella's mind was blank; after all, since noon yesterday until this afternoon, she had only had a simple meal and a cup of water—the rest of the time, she had basically given up on herself and lay sleeping on the ship.
In her drowsy dreams, every moment was filled with memories of the scenes that had happened that day, and sometimes she would even see in the pitch darkness, her brother's head alone staring at her, bleeding from all seven orifices as he spoke to her.
That terrifying scene made her nauseous, and under the immense psychological pressure of great fear, she almost didn't want to eat or do anything; however, her body was after all only a mortal shell, suffering from hunger in a way she could hardly bear.
Once she became too hungry, her mind was filled with only the simple thought of eating; but once she had eaten her fill, the chaotic thoughts would surge back into her mind.
