Earth Qi Immortal Gu

Earth Qi Immortal Gu resembles a butterfly, brown in color, and gives off a cloud-like qi. ^{ch. 2025}

Qin Ding Ling temporarily lends all three qi Immortal Gu for the qi path formation against Heavenly Court’s qi harvest fruit, with Heavenly Court able to reclaim them and strip control if needed. Disguised as Qi Sea Ancestor, Fang Yuan tosses Earth Qi Immortal Gu first while instilling immortal essence as the opening foundation of a formation that involves the earth vein; the Gu flies into the ground below the qi harvest fruit and earth qi rises from the shaken ground. Red Heart Traveler reads the resulting earth-vein disturbance as that first foundation taking effect on a main earth vein. ^{ch. 2025}

After the qi harvest fruit is gone and Qi Sea Ancestor presses for payment, Qin Ding Ling gives heaven qi and earth qi Immortal Gu but keeps Human Qi Immortal Gu as Heavenly Court’s bottom line and as bait for Triple Qi Retraction. ^{ch. 2037}

When Star Constellation Immortal Venerable suppresses Qi Sea Ancestor in Heavenly Court, Heaven Qi Immortal Gu leaves his immortal aperture first, then Earth Qi Immortal Gu and other qi path Immortal Gu, held for Primordial Origin Immortal Venerable. ^{ch. 2327}
