Corpse Oil? What kind of sinister spell requires the use of Corpse Oil? Could it be the Poison Art, which is a branch of the Maoshan Technique that's been shunned? It seems that only that requires Corpse Oil for casting certain spells, but isn't that universally despised by cultivators? No, no, no, that's not quite right, because there are those who practice Poison Art for benevolent reasons as well. However, it's clear that Yang Feng is not pursuing goodwill and virtue; he's after revenge on me. Ah, it's really frustrating, what on earth is it?
"Thank you for remembering our past brotherhood and telling me the answer. I have another small request now, I wonder if you could agree to it."
