Refining Immortal Gu could not be done with primeval essence, he needed immortal essence.

At this time, Fang Yuan took a look at the brass bell heavenly spirit, thinking about it, he directly used his green grape immortal essence to refine this Gu.

The brass bell heavenly spirit had no reaction, on the surface, Fang Yuan could not tell what mentality it had. It was just a bell after all, it had no expressions.

The refinement process was very smooth, the rank seven Immortal Gu resembling an ant queen did not resist, it cooperated with him.

But it was still a rank seven Gu, Fang Yuan's green grape immortal essence was greatly expended.

"Now, my stockpile of green grape immortal essence has dropped again." Fang Yuan reminded himself.
