Before Zhao Hai left, he met up with Louis. Louis was not only the captain of the cross blade Pirates, but he also helped manage Jaray 2. After all, all the members of his crew lived here. Zhao Hai wanted to tell him that he might not return to Jaray 2 here much in the future, so he would have to rely on him.
Zhao Hai didn't tell them that he was going to the hundred treasures world. In fact, they didn't even know about the myriad realm battlefield, let alone the hundred treasures world.
Zhao Hai also took some time to bring Margery to the Ashley family and asked them to help take care of planet Yaren 2.
