Shi Feiyang originally intended to follow Feng Wu in pursuit but unexpectedly encountered a "Flying Heart Gu" just as he was about to set off.
The "Flying Heart Gu" was an extremely tiny spider; smaller than the tip of a needle, it could bore into a person's body and reach the heart through the bloodstream.
The caster could communicate with the host through it. If the host dared to betray the caster, the "Flying Heart Gu" would lay eggs in the host's heart; numerous tiny spiders would hatch and devour it.
The "Flying Heart Gu" Shi Feiyang encountered was specially refined by Bai Guanhong for rescue purposes; it could ride the wind, dive into water, and enter the earth, displaying truly remarkable divine skills.
This "Flying Heart Gu" brought a message of a request for help to Shi Feiyang.
Previously, on the peak of Yellow Mountain, Bai Guanhong had allied with Shi Longgu to defeat the Heavenly Silkworm Immortal, and they took her back to Divine Dragon Island.
