Shi Feiyang had intended to follow Feng Wu in pursuit, but just as he was about to set off, he encountered a “Heart-Questioning Gu.”
The Heart-Questioning Gu was an exceedingly tiny spider, smaller than a needlepoint. It could burrow into a person's body and travel through their blood to nest inside their heart.
Through it, the caster could communicate mind to mind with its host. If the host dared betray the caster, the Heart-Questioning Gu would lay eggs inside their heart, spawning swarms of little spiders that devoured it.
The one Shi Feiyang encountered, however, was a “Flying Heart-Questioning Gu” that Bai Guanhong had specially refined to summon help. It could ride the wind, burrow through water and earth, and possessed considerable powers.
This Heart-Questioning Gu brought Shi Feiyang a message—a plea for rescue.
Previously, Bai Guanhong had joined forces with Shi Longgu atop Yellow Mountain to defeat the Heavenly Silkworm Immortal Maiden and capture her, taking her back to Divine Dragon Island.
After bringing her to the island, he had used the Heavenly Silkworm Immortal Maiden as a Gu Mother, refining gu insects through her body.
The Heavenly Silkworm Immortal Maiden had resisted repeatedly without success. All she could do was hope her master, Immortal Granny Dongxuan, would come rescue her soon.
Immortal Granny Dongxuan was also an expert who had reached the pinnacle of cultivation. Yet at such a realm, what she faced was the question of her future path, along with all manner of tribulations.
Her art of gu refinement had reached the summit of perfection, but her internal cultivation fell short. She could not even become an Earth Immortal.
In other words, although she had lived for over a thousand years, she had not survived by keeping an Earth Immortal's nascent soul in the mortal world.
