The fish's intestines were longer than Saleen expected them to be. A level seven Water Shield was able to last for about two miles of the journey before collapsing. In contrast, level ten would last over 20 miles. Things were hellish and chaotic in the fish's intestines.
The walls kept expanding and contracting. Any matter that entered the intestines turned into weapons against Saleen and his people.
Even if Saleen's calculative abilities were very bad, he knew it was a matter of time before things would take a turn for the worse. He said to others around him, "I don't think I'd be able to keep doing this till the end of the journey. If you guys have anything else to bring to the table, work with me and get things in order. We can only protect everyone here by doing so."
Sul answered immediately, "my liege, the golden sword aura would work, but it would only work with you, and I have no idea how long it would last."
