Ghost King City

Li Long and Zhao Ting had indeed been disciples of the World's Paramount Martial Academy. Moreover, Li Long had indeed killed Zhao Ting. However, Li Long had been locked up by the black donkey, and he hadn't actually entered the Celestial King Graveyard. He was replaced by Ling Han.

With a Heavenly Venerate helping Ling Han create a fake identity, it would be impossible for others to see through him, even if they were a disciple of the World's Paramount Martial Academy, and even if they were extremely knowledgable about the World's Paramount Martial Academy.

The Seventh Heaven Celestial King carefully interrogated him. In this place, they most detested Celestial Kings who entered to train, using them as whetstones. Thus, the numerous forces had all reached a consensus. If such a person appeared, they would all hunt down and kill them.
