"Aaahhh!"
The old man cried in pain after his arm was cut off! Blood splattered everywhere as the stench of blood wafted through the air.
Vincent didn't mind this as he hastily grabbed the arm and took the purple potion on it. He doesn't know what potion it was but it might be something precious so he wanted to keep it for later.
Pah!
Vincent slapped the Tower Master as he felt his head ringing after hearing him cry… The old man finally passed out but he was still bleeding.
Thud…
Vincent caught him and poured a healing potion on his arm to ensure that he won't die from blood loss.
He also concentrated for a bit to retract the Corrosive Mana that he had placed on the old man's body…
Well, the skill is originally called Corrosive Mana but since he's actually using Pseudo-Celestial Energy, this name might be called differently already.
