"Such an Exotic Fire is a rare sight. I happen to possess a stubborn Spiritual Material that ordinary Earth Fire and True Fire cannot refine in the slightest—a problem that has plagued me for ages. By chance, I sensed today that you, Fellow Daoist, possess an Exotic Fire, which is why I've brazenly approached you with this presumptuous request."
He set down his wine cup, his expression candid as he looked at Lin Changheng. "I am willing to offer you the Secret Skill, 'Smell the Wind and Distinguish Spirits,' in exchange. I only ask that you, Fellow Daoist, lend your aid once to help me refine that item. Whether we succeed or not, I will depart as soon as this matter is concluded and will never reveal the slightest information about you to anyone. If I go back on my word, may I suffer a Heart Demon backlash and my path of Cultivation be utterly ruined!"
With that, Wu Jiu had directly sworn an incredibly severe Heart Demon oath.
"Oh?"
