Han Sen had to go to Sky Palace, so he told Xie Qing King and the others. They were to take care of Planet Eclipse for him in the meantime, and they discussed plans for the future.
Han Sen was not worried about how Planet Eclipse would fare, nor Xie Qing King. As long as Han Sen's identity was not exposed, Yisha would also be there to safeguard the planet. No harm should come to Xie Qing King and the others while he was gone.
Han Sen was scared of people recognizing him in Sky Palace. If he was found out, all sorts of trouble could come.
The next morning, Xie Qing King called for a ship and had Han Sen shuttled off to Sky Palace in secret.
Sky Palace had many requirements for entry, so only proper students were allowed to enter the place. Han Sen was allowed in only because of his association with Yisha. None of his companions were, however.
