Looking at the cleared water area under their boat, everyone's faces turned awkward. If it was necessary to sacrifice someone to remove a blocking coffin, even if they sacrificed everyone on board, it would still be difficult to leave surrounded by dense coffins.
Furthermore, in the coffin that had previously opened in the distance, a creature resembling a water snake emerged. But when the water snake dove into the water, the coffin did not disappear. If they encountered that kind of coffin, they wouldn't know how to make it disappear.
Just as everyone was lost in their thoughts, the coffin that had trapped Little Five suddenly resurfaced. This time, after it rose to the surface, it shook continuously like the other coffins, as if something inside wanted to break out.
