As far as the eye could see, the vast sea of insects churned. Suddenly, enormous beetles with black-and-red bodies emerged one after another. They were three or four times larger than the surrounding insects, and rows of protrusions rose along their backs, each bearing clusters of hard, needle-like spines.
The moment those beetles appeared, a scarlet mist immediately spread outward.
As the mist surged forth, the surrounding insects abruptly grew frenzied. Their speed instantly became far swifter than before, and amid their shrill squeaks, they swept madly toward the city wall's barrier.
In the blink of an eye, the city wall's barrier, which had only just stabilized, once again began to show signs of instability.
"Fellow Daoist Qin, a large number of semi-mature demonic insects have appeared within this insect tide. Driven forcefully by those semi-mature demonic insects, the City Protection Array can still withstand them with everyone's combined support, but it has clearly begun to falter. Fellow Daoist, you must act quickly."
Faced with this sudden change, Fei You's expression shifted dramatically as he spoke urgently.
