The cave was rugged with jagged rocks, pitch-black and dark, winding and twisting as if leading straight to the Nine Netherworld.
The air had a distinct fishy stench, and after thousands of years of constant movement by insect beasts, the exposed rocks had long since been smoothed over, presenting an oily sheen with the dark soil.
The confined space and the grotesque insect beasts... as a training ground, every time the black-clothed Profound Guards of the Astronomical Bureau mentioned this place, they would spit heavily and curse continuously.
But now, the cave once densely packed with insect beasts was already empty, shrouded by billowing black mist.
After a moment, a rustling sound came from deep within the cave again, and a dozen or so insect beasts cautiously emerged, but as soon as they approached the black mist, they were ensnared and dragged inside by vines.
"Ha, what a profitable deal!"
