"What can you give me, then?"
Lu Heng's question was blunt.
The remnant soul fell silent for a moment, then let out an almost bitter chuckle. "You truly aren't one of those stubborn fools."
"Cut the nonsense."
"You came for the Infant Fallen Heart Flame, didn't you?"
Skyfire Venerable said,
"I know a sealing method. It can seal the Infant Heart Flame away for now, and you can refine it whenever you need it."
Lu Heng pushed the Cold Soul Jade in his palm forward slightly.
"Let's hear it."
Skyfire Venerable had probably not expected this young man to negotiate so decisively. After a brief silence, he drew a wisp of the soul-warming aura from the Ten-Thousand-Year Cold Soul Jade beside Lu Heng toward himself. The frail outline of his soul stabilized somewhat.
"The Five Spirits Fire-Locking Technique. This technique turns dou qi into five spirits and seals the Infant Heart Flame within your body. The Heavenly Flame's origin will remain intact, it will not affect the foundation of your dou qi, and you will not suffer the backlash that comes with refining a Heavenly Flame."
Lu Heng was satisfied. If he had not made demands, Skyfire Venerable might not have trusted him either.
"Deal."
Skyfire Venerable let out a breath, as though the final heavy stone weighing on his soul had finally fallen away.
"Bring the Cold Soul Jade closer to me."
The process of sealing away the remnant soul was more troublesome than Lu Heng had imagined.
After three hundred years of depletion, Skyfire Venerable's soul origin had become exceedingly frail. The slightest mistake could cause it to collapse completely. Lu Heng could only use the gentlest soul force to wrap around that nearly transparent remnant soul and guide it bit by bit into the Cold Soul Jade.
