Lu Ban saw that the groom had transformed into a merman, wandering in the Sea of Mud, and on the other side, the bride's body was also undergoing mutation.
The shape of her head changed, her clothes tore apart, revealing a body that was becoming hard and growing scales. In just a few seconds, the bride had become a merman just like the groom.
Perhaps the Hai Family people were never normal humans to begin with, but merman as they were now.
Under the influence of some supernatural reproductive force, the Hai Family people were gradually able to intermarry with humans and slowly took on the appearance of ordinary humans. Nevertheless, many of their ancestors still retained fish-like features, such as protruding eyeballs and wrinkled faces.
The zombies shrouded in the mist were probably the ancestors of the Hai Family.
They were cursed in some way, so that even in death, as long as they were in the mist, guarding the Divine Idol, they would not decay.
