Golden peanut shell

After lifespan Gu steps in the San Cha Mountain blessed land hall, Fang Yuan holds a Gu like a peanut shell, golden, with scarlet blood-trace markings on the surface. At that step the real second aperture Gu has already formed and is nurturing in the peanut shell. Only a strong external force from rank six divine travel Gu can eliminate the false Gu and make it real. ^{ch. 391}

When Gu refinement reaches the crucial period, the golden peanut shell collides with divine travel Gu. With the land spirit secretly pouring immortal essence, Fang Yuan activates divine travel Gu; it turns into light speckles and enters the golden peanut shell, and the qualitative change begins. ^{ch. 392}
