The biggest reason that he hired Black Star was because the other mercenary groups changed their mind and none of them dared go to Floating Dragon Island. He did not expect this small mercenary group to be the key to the success of the mission.
"My friends wouldn't have returned safely if it wasn't for you."
As he was speaking, he and all the rescued Silvers put down their sense of superiority as royalties and greeted Han Xiao with the sincerest way to express gratitude in the Silver culture.
