Upon Benjamin's return from the party he orders Conventoba to get in contact with Balsamilco to have him bring him the Fourth Prince alive as he'll kill him on his own. Benjamin also later orders his fourteen soldiers to not only act as bodyguards, but spies to the other Princes, he wanted them report back any information on the Princes Nen Beasts and the Hunters abilities. In case they come under attack or suspect any animosity coming from anyone, they have the right to defend themselves and have full permission to kill their opponent. Afterwards Conventoba makes contact and talks with one of Zhang Lei's bodyguards presumably to explain the situation.
