Too Weak

The Gu refinement hall was filled with bright white light.

The light was glaring, nobody could look at it directly.

An intense aura that was in-between mortal Gu and Immortal Gu showed that the Gu refinement was at its most crucial step.

Fang Yuan was bathed in the white light, his concentration was fully invested. Beside him, refinement path Gu Immortal Sixth Hair had a look of solemness and nervousness.

"Now is the time!" Suddenly, Sixth Hair spoke and dispelled the entire refinement path Gu formation!

Originally, the best way to refine heavenly secret Immortal Gu was to use light path refinement method. Other than that, other paths would only exert more effort for a weaker result, some even caused an opposing effect.

And at this final step, the refinement path Gu formation needed to be shut down, the Gu Immortal had to personally complete this final step.
