"Senior Brother, although these fish monsters are numerous, their intelligence is low. They're just cannon fodder."
One of the demon cultivators sneered, the black net in his hand unfurling once more, instantly ensnaring dozens of fish monsters.
The other demon cultivator held a fishing rod, giving it a gentle flick, as the hook pierced a Tier Three Fish Demon King's body like lightning.
The Fish Demon King let out a piercing shriek, struggled a few times, and then had its demonic power drained by the eerie force on the hook, turning into a dried corpse.
"These fish monsters' demon cores are good things, shouldn't be wasted."
The demon cultivator chuckled, casually storing the Fish Demon King's demon core.
