"Yeah, right here is where the pharmaceutical plant's drainage ditch used to be. The deepest part is nearly 15 meters. When the plant was digging this ditch, they accidentally hit an underground river, which is why the water is not only deep but also has two currents. One is from the underground river flowing towards the direction of the river, and the other is the river water pouring into this ditch, causing very serious undercurrents here."
Plus, since this place had been discharging pharmaceutical wastewater for decades, there were originally no fish here, but the grass inside the ditch grew exceptionally well. With water, sufficient depth, and grass, that means there will be large fish."
"Although I don't know who told you to come here to fish, it's not an easy task to fish in this place!"
The elder brother spoke at length, providing a very detailed introduction to the situation here.
