Kaila smiled. She no longer feared the Negative Trench. She understood that every number, no matter how deep or dark, had a path back to the surface. And sometimes, the only way to find the treasure was to solve for x .

the eel hissed. Its voice was the sound of a thousand calculators crunching numbers. “Swim through the false statements, and you dissolve.”
“To open it,” Gus’s voice crackled through the helmet radio, “you gotta punch in a sequence that equals -8. But you can’t just go straight down. The current will rip you apart. You gotta use the seabed paths—add and subtract your way there.”
The eel uncoiled.
Kaila descended into the trench. The water grew thick as syrup. Strange, translucent eels slithered past, their bodies shaped like parentheses and division signs. Then she saw it: the Eel. It was enormous, coiled around a single, perfect, silver pearl. Its scales were made of mathematical statements.
