If the existence of Half City itself was a taboo in the Morning Star Sea Realm, then in Half City, there was a taboo inside the taboo!
It was Demonic Woman Ning Bi.
It was said that this was a name that she gave herself, and her real name was like a curse that would bring catastrophes if it was pronounced. Even the cultivators in Half City didn't dare to mention it, and it eventually disappeared in the long history.
Some said that she was the descendant of devils and demons, and some said that the ruined half of Half City had been destroyed by her.
Of course, due to the great length of history, no one could prove the rumor. Some evidence even showed that she had actually appeared in Half City many years after that catastrophe, but nothing could change the fact that the people in Half City feared demons.
