Inside the cave, Dick was absorbing the soul-refining pill.
He could feel that the dark doppelganger and Wolf Emperor were struggling to fight outside. He was even more anxious, and his soul had a violent fluctuation.
"No, I can't do this. If I care too much about what happened outside, I can't absorb the soul-refining pill. What's more, my soul will be damaged and I can't go to rescue them."
Dick tried his best to suppress his anxiety and dispel his distracting thoughts. He used his soul sea to completely wrap up the soul-refining pill that he hadn't absorbed yet, making it slowly integrate into his soul.
When there was only the last smidge of the two soul-refining pills left, Dick felt a burning pain in his soul as if there was an endless fire burning in it, making him unbearably painful.
