Because, after losing the pursuit of the nocturnal species, the "rustling" sound in the air did not disappear; instead, it seemed to be replaced by his perception tentacles, beginning to emit a "rustling" sound from the map level...
"Wei Sang, do you think there are any students in the classroom who have been transformed from pseudo-human sculptures? Those nocturnal species, could they still be huddled deep within the Green Forest Belt?"
By day, the nocturnal species seemed to be summoned by something, lurking deep in the Green Forest Belt, and now, whether the pseudo-human sculptures have turned back into pseudo-human students returning to the classroom, it doesn't feel like a good thing.
If they don't return, it's as if they have a conspiracy in the Green Forest Belt;
If they return, it's as if they've already plotted, starting to cast and reel in the net.
Either way, it's not a good thing.
