Bi Fang kicked the strange fish back into the Underground River and hastily moved up the riverbank to avoid being ambushed by the fish again.
The water of the river flowed silently, and the fish, forming dazzling swirls of light as they swam in circles, were actually glowing!
The bioluminescence was even bright enough for Bi Fang to clearly see this grand and magnificent place!
What an inconceivable miracle of life!
Was this bioluminescence coming from inside the cells or from their exterior?
Why was it so bright?
The phenomenon of bioluminescence is not uncommon, especially for fireflies on land, which are the most well-known examples.
An Underground River filled with so many bioluminescent fish; what species could this be?
Gu Qingyuan had fallen into deep thought, while Wu Gang beside him didn't entertain such roundabout ideas; he was simply immersed in the vast and unknown depths of the earth.
So thrilling!
