Chapter 516: Profound Yin Classic

First of all, this item could not possibly be a real rib bone of the Xuan Gu Old Demon; its current shape was just a means for the old demon to deceive people.

Not to mention the special material, just the trace of spiritual energy faintly emitted from it was enough to know that even if it wasn't some Magic Treasure, it was definitely an item that had been refined by someone.

But no matter whether Han Li probed with his spiritual sense or slowly injected spiritual power, this rib bone had no reaction at all.

After Han Li frowned, he immediately remembered that the old demon practiced the demon and ghost path, so perhaps this item must rely on some ghost energy.

Although Han Li himself did not have ghost energy, the Soul-Gathering Bowl he obtained in his early years was still on his body.

Although the ghosts in the bowl had long been consumed by him in refining puppets, the residual ghost energy in the bowl was still quite a lot.

So he pressed his hand into his storage bag, and the pitch-black round bowl appeared in his hand.

Han Li glanced at the Soul-Gathering Bowl casually, and green light flashed on the five fingers supporting it.

Strands of ghost energy were absorbed into his body by Han Li through his palm, and then slowly transmitted to the other hand holding the bone block.

A ball of cold, black energy gradually took shape and soon wrapped around this rib bone.

Han Li stared at this scene without blinking.

The rib bone finally reacted; the originally white and smooth surface began to turn black, and before long, the entire ball of ghost energy was absorbed into the bone, turning it half-white and half-black.

Seeing these changes, Han Li didn't reveal any unusual expression on his face, but instead, his eyebrows twitched inadvertently.

After closing his eyes and thinking for a while, Han Li sat up from the bed.

Then, the palm of the hand holding the Soul-Gathering Bowl erupted with even more dazzling green light.

At the same time, the sound of ghost weeping came from the other hand, and an even larger ball of pitch-black ghost energy took shape.

The rib bone wrapped inside was devouring these ghost energies frantically without any courtesy.

After a full cup of tea's time, the continuous inhalation of ghost energy gradually made this object turn equally pitch-black.

Suddenly, a low humming sound came from this object, and then strands of pitch-black light bloomed, and the room was suddenly filled with a bizarre, eerie atmosphere.

Han Li somewhat hesitantly put away the Soul-Gathering Bowl, and at the same time, his five fingers loosened, and the rib bone floated out, while the ghost energy wrapping it dissipated under the impact of the black light.

Looking at this bizarre scene, Han Li's gaze flickered constantly.

But besides humming constantly in the air and the black light flashing, the black bone block had no other changes.

After a while, Han Li's expression moved, and he suddenly beckoned toward the air.

With a "whoosh" sound, the rib bone was sucked toward him out of thin air and grabbed firmly in his hand.

Then Han Li stared at this object, and his spiritual sense penetrated into it.

This time, there was no longer the feeling of being unable to penetrate it. His spiritual sense entered the rib bone very smoothly.

As a result, after a flash of black light, one after another, large ancient characters and pictures appeared before his eyes.

"Jade slip," Han Li muttered to himself, not revealing an overly shocked appearance.

This item could be a specially made jade slip; this was also one of his prior conjectures.

So he suppressed the excitement in his heart and began to ponder it carefully, word by word.

"Profound Yin Classic"

After reading only the somewhat familiar characters in the first half, Han Li completely confirmed the content of the incantation.

Although he had never practiced this famous demonic cultivation technique, the "Blood-Refining Divine Light" practiced by his clone was completely derived from this technique, so the content was naturally quite similar.

Therefore, after reading the first part of the technique, he concluded that it was this.

And this rib-like jade slip was the so-called "Profound Yin Classic".

To be honest, Han Li was somewhat disappointed.

He had already practiced the Azure Essence Sword Art, and although the Profound Yin technique was extremely overbearing and powerful, he wouldn't be stupid enough to re-practice this technique.

However, he didn't immediately withdraw his spiritual sense from the Profound Yin Classic and continued to read sentence by sentence.

Because the second half of the Profound Yin Classic also recorded some demonic secret techniques, and these were not all impossible to practice.

As one incredible secret technique after another unfolded, Han Li's expression changed from disappointment to pleasant surprise, then gradually mixed with a trace of solemnity, and finally, his entire face was full of a hint of excitement.

The power of these secret techniques was truly incredible.

He was confident that if he could practice the Azure Essence Sword Art to the ninth layer and cooperate with the secret techniques that could be practiced in the Profound Yin Classic, although he would still not be a match for Nascent Soul stage cultivators, he would have a chance to save his life and escape.

Meeting old monsters like Extreme Yin would no longer mean he could only be destroyed without any means of response!

Among these secret techniques, Ancestor Ji Yin's "Heavenly Capital Corpse Fire" was prominently included; as for the "Heavenly Capital Demon Corpse," it was merely a corpse-refining byproduct produced during the cultivation of this secret technique.

It's a pity that this secret technique must be based on the Profound Yin technique and requires a cultivation base of Nascent Soul stage or above to practice. Otherwise, he would have been interested in trying it.

After all, he had witnessed the power of the Heavenly Capital Demon Fire with his own eyes; it was indeed sharp and unparalleled.

However, even so, the weaknesses of this demon fire were clearly leaked from the practice incantations.

Seeing this, Han Li sneered in his heart!

If Extreme Yin used this demon fire against him next time, he would definitely be able to shock the other party!

After reading for a while, Han Li memorized two or three secret techniques that he took a fancy to and could be practiced at the Core Formation stage. He prepared to practice them when he had time in the future.

Carefully putting away the small rib bone containing the Profound Yin Classic, Han Li was very satisfied with this harvest, and there was still a hint of excitement in his heart that he couldn't suppress.

After pondering for a while, he touched the Void Heaven Cauldron in his storage bag, and his curiosity burned.

He immediately set off toward the secret room of the cave dwelling.

If he could open the Void Heaven Cauldron in one go, not to mention the Heaven-Mending Pill, even obtaining a few more ancient treasures would greatly increase his strength.

Holding this thought, besides observing the Golden Silk Silkworms once a day, Han Li spent his days and nights studying the small cauldron, and occasionally searched through various ancient classics to see if he could find a way to open the cauldron.

Unfortunately, half a month later, Han Li, who had racked his brains and tried every means, had to admit that this Void Heaven Cauldron, known as the number one secret treasure of the Chaos Star Sea, was indeed not something he could open at the Core Formation stage.

This cauldron was truly extraordinary!

Not to mention fire burning and water drowning, Han Li had tried all his Magic Treasures and ancient treasures, but couldn't leave half a mark on the cauldron wall. And when he used the trace of Evil-Warding Divine Thunder that had just recovered from the Azure Bamboo Cloud-Swarm Swords to strike the cauldron, there was no reaction at all.

As for other incredible ways to open the cauldron, Han Li tried them all, which naturally ended in failure.

Finally, Han Li could only give up and put the small cauldron back into his storage bag.

As for the Dry Blue Pearl that Han Li suspected might be greatly related to opening the Void Heaven Cauldron, he dared not touch it easily.

The Dry Blue Ice Flame was an existence that even Nascent Soul stage old monsters feared.

Before his cultivation reached the Core Formation late-stage or he condensed the Nascent Soul, he had no intention of manipulating or refining this pearl.

Han Li still had this self-knowledge.

During this period, the two Golden Silk Silkworms that had taken the five-colored spheres still had the same situation, without any major reactions; it seemed the medicinal properties had not yet been exerted.

Instead, the tens of thousands of Gold-Devouring Insects in another insect room finally began to devour each other on a large scale. It seemed that new Gold-Devouring Insect eggs were about to be born, which made Han Li overjoyed.

Now, the next thing Han Li had to do was to re-refine the seventy-two Azure Bamboo Cloud-Swarm Swords.

He had no intention of wasting the refining crystals he obtained on the lava road at all, and prepared to refine this crystal into the flying swords bit by bit.

In this way, although he wouldn't dare to say that his Azure Bamboo Cloud-Swarm Swords were indestructible, there were truly very few things in this world that could destroy them.

This would be of great benefit to his battles with high-level cultivators in the future.

However, refining this crystal was an absolutely arduous task.

Given the special material of this item, although the classics didn't say much about it, Han Li estimated that it would take at least half a year to slowly refine this crystal with the help of a magic formation.

If he suddenly ran out of magic power and couldn't maintain it halfway through the refining process, this crystal would be completely destroyed.

This was not a joking matter!

If it were before, with only a Core Formation early-stage cultivation, even with various spirit herbs to assist, he wouldn't risk trying it.

But now that he possessed ten-thousand-year spirit liquid, although he had used up a portion of it before, the remainder was enough to keep him from worrying about running out of magic power.

Instead, considering the many dangers he would encounter when going out to sea to hunt monster beasts, the sharper the Magic Treasure, the better.

In this way, Han Li had to re-refine the flying swords!
