Scorpions do not have ears.
They rely entirely on the sensory hairs on their body surfaces to detect movement.
So when the scorpion was moving about within the "Barrier," feeling the direction of the surrounding airflow, Jiang Yan, with her sharp eyes, caught sight of it in a second.
She narrowed her pupils and quickly grabbed a bottle of insecticide while pointing in the direction the scorpion was crawling with her other hand,
"There's a scorpion!"
"Snap!"
In the flash of a flame, a sharp dagger fell from above, aiming straight for the heart of the scorpion. A small amount of viscous fluid splattered out.
It was Song Qian.
After struggling for a few seconds, the scorpion's limbs stopped moving.
"Jiang Yan, did you see where it crawled out from?" Song Qian looked at Jiang Yan.
Jiang Yan pointed in the direction from where the large scorpion had emerged, "It crawled out from that pile of rocks."
