"Aaahhh!" The pain intensified almost immediately. It didn't do much earlier, but it jumped straight to be pierced by a nail from an ant's sting.
Alex said no more and focused on his task. It might be due to the experience of pain himself that he thought this level of pain was nothing extraordinary. If they couldn't even withstand this pain, they might die after feeling the pain from the Undying Fire Body's refining.
However, it seemed they were not a pushover. After experiencing the pain for several minutes, they gradually adjusted their breathing, so they could endure it better. Their screams died out to the point they only let out some groans during this process.
"Ho?" Alex smirked as he kept refining their organs according to the technique. Rena seemed to be the one adjusting better. 'She seems to have something more even though her talent is lower than Rio. Not that I care about them since I will probably leave this world before they can rise.'
