Realizing that the secret realm he was currently inside was not actually a secret realm but instead a mystic realm- and one that he had likely already been to in the past, Chu Yang could not help looking through the information again to make sure he had not read anything wrong.
Only after he calmed himself down from this sudden revelation, did he continue reading through the rest of the information. Finding that outside of a bit more information regarding the outer region of the mystic realm that he now found himself inside of, there was also information on the Dead Spirit Canyon- Or more specifically the dark waters the flowed through the Dead Spirit Canyon.
The information in question noted down the origin of the dark waters as being a place called the Dark Spirit Ocean, a place teeming with terrifying creatures that had been sealed away by the Mirage Sect in the past.
