"So impressive, this Gu formation can actually control Reverse Flow River." Flood Extremity looked at the pillar of light and praised sincerely.
But Black Extremity shook his head: "This is not control, I merely created the fate reversing sacrificial refinement formation, it is like digging a river channel and letting Reverse Flow River move in it. We dug the river channel, thus, we can influence the direction that Reverse Flow River goes."
"When we retrieve Reverse Flow River, Longevity Heaven will gain another secluded domain of heaven and earth." Flood Extremity anticipated.
Black Extremity instructed again: "When we collect Reverse Flow River, the sub formation will be destroyed. You have to take note of the time and direction, opening your immortal aperture and letting the river flow in. You are a water path Gu Immortal, you have a big advantage in doing this."
