章 1440: Great Dream Immortal Venerable Feng Jin Huang

Northern Plains, Lang Ya blessed land, Gu refinement hall.

The refinement path Gu formation slowly operated, the eerie blue cold fire had already turned into an iceberg.

Fang Yuan stood at the edge of the refinement path immortal formation and raised his hands, closely pressing his palms onto the iceberg.

His eyes shone brightly as he put almost all his concentration into the Gu refinement.

All kinds of Gu worm auras fluctuated in his body, there were auras of mortal Gu as well as Immortal Gu. He was using large amounts of refinement path methods as well as killer moves.

Under Fang Yuan's effort, the blue cold fire was still quietly burning inside the iceberg.

Gu materials were constantly refined by the fire, their impurities were removed, leaving behind only the purest essence.

An Immortal Gu embryo was beginning to form little by little.

Sixth Hair, who was standing at the side, was observing with a joyful look.
