"Indeed, before the defeat, the Witch of the Star River established a unique law with her magic power to save the witch civilization, allowing the souls of dead witches to wander across the universe, seeking intelligent species to 'parasite', passing on the witch's civilization.

Obviously, witches only parasitize intelligent beings, so the knowledge of the Yousu people had a chance to be passed along with the worlds where witches parasitized," said the Shining Will Entity.
"And your 'Star Deity' clan continues to wander..." Xu Yang contemplated.
