Chương 1657: Clues of Regret Gu

Inside the small house, there was a huge turbulence.

Dark red lights moved like waves, surging around Fang Yuan.

He was refining Gu.

His ten fingers were outstretched, his two hands were holding onto an eerie ball.

This ball was basin-sized, it was flowing on the surface, this was the essence of the black oil that Fang Yuan extracted.

The Gu refinement was already at the late stage, now was a crucial moment.

Fang Yuan willed as a crack opened in his immortal aperture's entrance, he took out a piece of shiny golden scale.

The scale flew into the black oil ball, causing a small explosion. In Fang Yuan's vision, he saw that the instant the black oil ball exploded, it expanded rapidly. At the same time, the golden light shined in the black oil ball, before condensing into a small dot.

Fang Yuan's ten fingers vibrated, the black oil ball floated into the air and started to revolve around itself.
