章節 1684: Profound Literature Grotto-heaven

Immemorial white heaven.

Fang Yuan was moving forward on an auspicious cloud.

Half of his concentration was in the sovereign immortal aperture and the other half was on guard.

If it were before, Fang Yuan could not have split his concentration when refining Gu. But his gains were truly huge during this recent period of time.

He lacked neither attainment levels nor Gu recipes, his only shortcoming had been insufficient hands-on practice.

Personally refining Gu helped him grow rapidly in this aspect, his success rate in refinement increased greatly and so the amount of immortal materials wasted had also decreased by a lot.

Refining Immortal Gu had always been a sinkhole, besides Gu refinement, Fang Yuan was also plundering all kinds of natural resources from immemorial white heaven.

He sold a portion in treasure yellow heaven and bought items he needed for refining Gu and managing his immortal aperture.
