The old site of Peach Lands, at the moment of darkness and new moon.
Following the ancient technique taught by Kui Ba, Xu Qing used corpse blood as a lure, delving into the forbidden land alone, attempting to bait Ying Gou's residual will into noticing, hoping to find traces of that blue-gold source.
The ancient tree dragons in the thousand-mile Peach Lands are withered, in every crevice of rocky cliffs, various bird and beast skeletons can be seen.
Occasionally, human bones who stumbled into the forbidden land also appear.
Along his route, Xu Qing recited the Sutra of Salvation, spotting traces of Ying Gou's quest to extract life essence from the victims and reconstruct its own body.
The Ying Gou was formless and invisible, essentially an eternity of gathered corpse evil.
When the corpse evil landed on vegetation, they would transform into venomous beasts, sucking blood marrow from humans; touching stones would turn them into fire spirit phantoms, devouring human essences.
