Daimon turned to see Thea who nodded, he didn't need to say anything, for the Black Empress to scan everyone in the room to see if there were some contracts that needed to be nullified.
Which was of course the case, the fat guy and the informant were the ones that required Thea to use her innate ability, the four half Stellar ranks were tied to the fat guy, so Thea first erased those contracts, which made the guy vomit blood.
Despite the riches and the fact that he had some decently strong subordinates, for being a mere slave merchant, he was just an early-stage Arch rank, and his battle prowess was super trashy, meaning he just advanced by consuming resources.
So, the backslash of the contracts breaking hit him pretty hard, unfortunately for him that wasn't the end of his suffering.
