A few moments ago, Nyx had followed the voices and sounds of fighting. He could hear the Gorgon and humans growling. It was later that he would discover that it was actually Asher.
Following the sound, the red-haired boy took many turns and twists before finally arriving at this passage, the passage where Asher, Thalia, Simon, Bai Long were currently present. After seeing them, however, Nyx didn't reveal himself and instead started thinking of a plan, a plan to steal their monster cores which were piled into a small heap at the side.
If Nyx were to give an estimate, he would say those cores were up to 12, which was a large amount considering he had only met a few Gorgons that didn't even exceed 10.
