"Who are they?" Chu Yunsheng asked, while there were feelings emerging in his heart. This kind of feeling had appeared before, but he couldn't remember exactly when at the moment.
The giant head shook its head again and again: "No one knows, no one ever knows. They seem to be determined to eliminate all traces of their own existence, except for the traces of Eternal Suppression at the entrance and the exit that cannot be erased. So far, none of the other Descenders we have encountered and communicated within the eight galaxy realms have found traces of them anywhere else. All the legends about them have been spread and fabricated from the knowledge of all kinds of life about the mythical techniques that they used to complete the Eternal Suppression at the entrance and exit of the Rainbow Bridge."
