"I see..." Lin Tian suddenly understood, but immediately another doubt arose in his heart, prompting him to ask again, "The vortex can be explained as the impact of the tide, but there's a stream of water that's green, why is that?"
"Algae, we call it green algae. In one of the Underground Rivers, there should be a large amount of this green algae living there. Normally, the green algae attach to rocks and the riverbed, but when the Underground River swells, they are carried out by the water flow. Because the river water contains a large amount of green algae, it appears green -- this is the power of nature." Wang Mingyan explained in detail.
"It's truly incredible..." Lin Tian and Ghost both exclaimed in amazement.
While the few were discussing, Mr. Wang, who had been motionless on the opposite shore, suddenly opened his eyes. In those profound eyes, there seemed to be two vortices, reflecting the celestial phenomena in the lake, or perhaps two endlessly rotating Tai Chi symbols.
