Under the horrified eyes of the other pirates, Blackface screams became louder before he started smacking his face against the ground by himself, while the Risha sisters and Mellie showed some discomfort of the current scene of Blackface destroying his face until all that was left was a bloody mess, Daimon and Aisha didn't change their expressions at all.
Blackface was a mage and in his current mind state didn't use mana to reinforce his body, his body was just a bit tougher than a grown adult, so it didn't take more than twenty solid smacks, for him to kill himself.
Only then, Daimon turned to see the other pirates whose bodies were restrained by Liliana's ice from which they didn't dare to try to escape as they all had weapons pointed at their heads or necks.
