The bubbling area was precisely at the end of this polluted tributary.
As he approached, Su Mu reached out and grabbed toward the bubbling water surface.
Then, his fingertips touched something slippery.
Immediately, that slippery thing started to run away.
Run?
Su Mu concentrated, making this part of the waters static, then reached out again and caught it, yanking it out of the water.
It was a pitch-black giant fat catfish, with two pitch-black eyeballs. Looking closely, one could see a hint of black light swirling in its pupils. It was quite large, about 1.2 meters in length, with two long, black-red whiskers on its upper lip.
After capturing this giant fat catfish, the color of this section of water turned slightly lighter. The change was very subtle, but it did not escape Su Mu's eyes.
Then, after Su Mu released the giant fat catfish back into the water, the color of the water deepened again, returning to its previous blackness.
Seeing this, Su Mu's eyes lit up.
