A Record of A Mortal's Journey to Immortality

Chapter 517: Profound Yin Scripture

First of all, this item could never really be a rib bone from the mysterious bone old demon. Its current form was merely a means for the old demon to deceive others.

Setting aside the special material, just the faint spiritual energy faintly emanating from it proved that it was not some ordinary magical treasure, but it was definitely an item that had been forged through ritual refinement.

However, whether Han Li used his spiritual awareness to probe it or slowly injected spiritual power into it, the rib bone showed no reaction whatsoever.

Han Li frowned, then immediately recalled that the old demon cultivated the path of demon ghosts. Perhaps this item required some form of Yin soul energy to activate.

Although Han Li himself did not possess Yin soul power, he still had the Soul-Gathering Bowl from years ago.

Though the Yin souls within the bowl had long since been exhausted by his puppet refining, the residual Yin energy in the bowl was still considerable.

So, he pressed one hand into his storage pouch, and a pitch-black round bowl appeared in his palm.

Han Li casually glanced at the Soul-Gathering Bowl, and the five fingers supporting it suddenly flashed with azure light.

Traces of Yin energy were absorbed into his body through the palm, then slowly transmitted to the other hand holding the bone fragment.

A cold, black aura gradually took shape, quickly enveloping the rib bone.

Han Li stared unblinkingly at the scene.

The rib bone finally responded; its originally white and smooth surface began to blacken. Before long, all the Yin energy was absorbed into the bone, turning it half white and half black.

Seeing these changes, Han Li showed no particular expression, only a slight twitch of his brow.

Closing his eyes to contemplate, he suddenly sat upright on the bed.

Then, the palm holding the Soul-Gathering Bowl erupted with an even more dazzling azure light.

Simultaneously, the other hand emitted the faint sound of ghostly wails as an even larger mass of pitch-black Yin energy materialized.

The rib bone trapped within ravenously devoured the Yin energy without restraint.

After nearly a tea break’s worth of time, continuously absorbing Yin energy, the item gradually turned equally pitch black.

Suddenly, a deep humming sound emerged from the object, followed by streaks of black light blossoming forth, filling the room with a strange and eerie atmosphere of gloom.

Han Li hesitated slightly and withdrew the Soul-Gathering Bowl. At the same time, he relaxed the grip of his other hand, letting the rib bone float out. The Yin energy enveloping it dissipated completely under the assault of the black light.

Watching this bizarre scene, Han Li’s gaze flickered constantly.

Apart from the low humming and the persistent flashing of dark light in midair, the black bone chunk showed no other changes.

After a while, Han Li’s expression shifted, and he suddenly waved toward the air.

With a "swish," the rib bone was sucked toward him from thin air and firmly grasped in his hand.

Then Han Li stared intently at the item, sending his spiritual awareness into it.

This time, he no longer felt the impenetrable barrier he had encountered before. His spiritual awareness smoothly entered the rib bone.

In an instant, dark light flashed before his eyes, and large ancient characters and diagrams appeared one after another.

“Jade Slip,” Han Li muttered softly, clearly shocked.

This item might be a specially made Jade Slip, which was also one of his earlier guesses.

Suppressing his excitement, he began carefully studying each word, one by one.

“Profound Yin Great Technique.”

After reading the first half of this somewhat familiar phrase, Han Li was fully convinced of the content of the spell formation.

Though he had never practiced this infamous demonic cultivation method, the “Blood Refining Divine Light” that his clone cultivated originally came entirely from this spell formation, so naturally there were many similarities.

Thus, after reading the initial spell formation, he deduced this conclusion from the commonalities among various cultivation techniques.
