Why was Hui Wang killed when Xia monk was investigating the case?

King Hui was killed because Ling Er, who became a zombie and lost his will, was killed. Hui Wang, a martial arts detective, came from a legendary martial arts detective movie, and Hui Wang was killed by Linger, who turned into a zombie (according to the smell of the corpse, Mo Liqian said that Zhao Hui was not worthy of his own hand. One more thing, that is the little white Yu Pei in Hui Wang's hand, and the Yu Pei that can only be taken away by Linger).
