As for deeper locations, Lin Yang had not considered them yet, because the measured depth at this spot was only about twenty to thirty meters.
Since the big fish had appeared on the surface, there were chances in the upper layers as well.
After setting the depths for the two fish, Lin Yang adjusted the unloading force of the fishing device again, making sure it was set so that a fish weighing several dozen pounds could not pull it free, but a bigger fish, such as one weighing over a hundred pounds, could still get hooked when it bit.
Seeing him expertly set up the fishing device, Han Li asked curiously, "Mr. Lin Yang, what's the principle behind this fishing device? It seems that if a big fish is caught, wouldn't it just drag the device away? Do we need to tie extra ropes to secure it?"
