"Click!"

Suddenly, there was a slight sound of bones shattering.

Xiao Chen cautiously swam in the abyssal pool. The remains of corpses floated on the surface of the pool. The wreckage had apparently been scorched by the previous fire, and was almost incomplete, and, due to the heat, all of them were extremely crispy, shattering at the slightest touch.

Swimming all the way, Xiao Chen's movement of throwing his arms and pulling the pool liquid to swim forward had already broken a lot of such wreckage.

But this one is clearly different.

Subconsciously turning his head, he glanced at the wreckage with the sound of bone cracking coming from the side, and Xiao Chen's gaze happened to catch a withered head that was splitting itself.

This was a skull that had already been shriveled and blackened by the fire, and at this moment, when he touched it lightly, the entire head was split into two halves from the Heavenly Spirit Cover like a split watermelon, but the traces of the crack were not so neat.

I have to say that this scene looks really chilling.

Xiao Chen's eyes widened suddenly at this moment.

In the cracked skull, a crimson crystal the size of a pigeon's egg lay silently, refracting the glow cast by some of the burning fires on the distant pool.

Xiao Chen suddenly stopped his movements, and cautiously reached out and took the crystal into his hand.

Stygian Crystal!

A strange term popped out of his memory and appeared in Xiao Chen's mind.

This thing is condensed by the energy remaining in the bodies of these corpses that have been up and down for thousands of years in the abyss. It is a crystalline body with a high concentration of residual energy within the entire corpse.

However, not every corpse has this in its skull.

The reasons for its formation are quite mysterious.

In addition to the scorching forging of the dark fire, it seems to be related to some ethereal things such as obsession and resentment.

Because of this, although this Dark Crystal was a crystallized body forged from the entire residual energy of some corpses, it could not be allowed to be refined into the body at will by the corpse cultivators like the endless corpse qi in the abyss.

It contains the obsessions and grievances of these corpses before their deaths, which are extremely difficult to refine, and the gains outweigh the losses!

"In the skulls of corpse......s? That's what the flowers of Hadesa came from?"

Playing with the crimson crystal in his hand, Xiao Chen suddenly had a bold guess.

If this is the case, the Stygian Crystal should be like a seed, which has been forged by the Stygian Fire and some other unknown factor before condensing in the skull of the corpse.

Ji'er slowly sprouted, growing rhizomes, until Zuihou gave birth to a Hadesa flower that stretched out from the corpse's big mouth in anger?

However, what is the "Stygian Crystal Fruit" that Firebeard Zombie is talking about?

If this thing is a "seed", then the so-called "Immortal Crystal Fruit" is also in this form?

Since the seed is full of obsessions and resentments and cannot be refined, it is only after its "flowers" and "fruits" that these resentments and obsessions can dissipate, producing some mysterious changes......

For a while, a series of questions popped up in Xiao Chen's mind.

"It's a pity, it's obviously a kind of energy that is purer than corpse qi, but it can't be refined at all, it's not even as good as jelly beans!"

"Anyway, there is no way out now, strength improvement is the king, I'll give it a try, let's use a dead horse as a live horse doctor!

With a kind of pride in his self-muttering, Qin Luo gritted his teeth and threw the red crystal in his hand into his mouth.

Feeling a little sorry to himself, Xiao Chen smiled bitterly and threw the red crystal in his hand into his mouth.

Being in the endless abyss of corpses, everything he has seen and heard in the past few days is bones, and what is even more speechless is that even his body has become a withered corpse, for these things, Xiao Chen has already passed the rejection period, as if he has immunity, and he will not feel slightly disgusted at all because this thing has just been taken out of the skull of a corpse.

"Hey, this ......"

When the crystals enter the mouth, there is really a slight sweet feeling.

Suddenly, Xiao Chen soon discovered that the red crystals in his mouth were quietly melting.

It's so slow that it's almost avoidable, but it's definitely melting.

This is not a delusion!

At this moment, he almost had an illusion.

It's as if what I just threw into my mouth is really just a jelly bean.

Xiao Chen immediately became interested.

Turning his head to look around the pool, he saw that there was no unfavorable situation in the surrounding quiet, he immediately calmed down, quietly swam to a small wreckage island formed by the accumulation of some corpses next to him, climbed ashore and found a small wreck ridge with a height of a few feet, hid his body in it, and shrank in it to study it carefully.

He smacked his lips and stirred the red crystals in his mouth with his tongue, which was still not very neat, and the slightly sweet feeling immediately appeared on the tip of his tongue.

Xiao Chen took out the crystal and looked at it carefully for a while, the naked eye couldn't see the traces of it melting just now, and after a little hesitation, he threw the crystal into his mouth again.

Immediately, the feeling that the crystals were slowly melting came out of his mouth again.

In order to verify whether the crystal was really melting, Xiao Chen decided to use the stupidest method.

Wait!

At the moment, he hid on the small wreck island, and sat there stupidly, stirring the "jelly beans" in his mouth from time to time.

I don't know how long it took, Xiao Chen took out the crystal and looked at it, and a flash of surprise immediately burst out in his eyes.

Obviously, the jelly beans are a little smaller!

It's definitely melted away.

With a flash of inspiration in his mind, Xiao Chen stood up from the skeleton island.

Stretching out his arms and shaking his legs, his movements were obviously a little more flexible than before, and his entire withered body seemed to have added a little vitality, and there was a feeling of being "charged".

Who said that this kind of Immortal Crystal can't be refined?

Could it be that none of those stupid asses of the Underworld Corpse Sect have ever eaten jelly beans?

Xiao Chen was completely excited, raised his hand and threw the crystal into his mouth again.

After the crystal entered his mouth, he immediately began the process of quietly melting again, but what Xiao Chen could not perceive, there was a trace of invisible silk thread that was invisible to the naked eye, and it also quietly escaped from the crystal with the process of crystal melting, as if it was sucked by an equally invisible liliang, and spread towards the "ghost face dark lamp" tattoo on his chest......

After waiting for a long time, the whole crystal finally melted completely, and there was not a trace of residue left.

The energy contained in the entire crimson dark crystal would be completely refined and absorbed by Xiao Chen.

This simply subverted the cognition in his mind about the cultivation path of the corpse cultivators of the Underworld Corpse Sect.

The fact that the "Stygian Crystal" can be refined is not mentioned for the time being.

His current strength is only in the realm of the "General-Rank Iron Corpse", but the color of this Immortal Crystal "Seed" is red, and it is obvious that if he goes further, the flower of the Immortal Crystal will be a crimson "King-rank Bronze Flower".

Generally speaking, even if you have the secret method of the Immortal Corpse Sect, the King-level Bronze Flower can only be refined into the body by the corpse cultivator who has the body of the "King-level Bronze Corpse", and the purity of the energy contained in the Immortal Flower of different levels is different, and the realm is too low to withstand it at all, and there will be a danger of exploding.

But right now, Xiao Chen has really refined a "Crimson Crystal" that is higher than his own realm.

Is it because the Crystal is different from the "Flower of Hades"?

Or is it because this kind of shackles that can only refine the "Dark Flower" corresponding to his own strength are useless to him?

If you can get another silver Emperor-rank Immortal Crystal, or even a golden Emperor-Rank Immortal Crystal, try to see if you can refine and melt it as well, and this question will be answered immediately.

These thoughts floated in his mind, and Xiao Chen was so excited that his whole heart seemed to be no longer dead, as if he had vitality, and "thumped" and "beat".

If even the higher-level Immortal Crystal could be refined, and its energy could be melted to nourish its own body, I am afraid that this withered Immortal Corpse Body would immediately be able to soar in strength like a rocket because of a large amount of rapid nourishment.

Others absorb corpse qi into their bodies, or occasionally hit the great luck to obtain the same level of dark flowers, and refine them to improve their strength.

However, Xiao Chen was able to refine a higher-grade Dark Crystal.

This is simply an upgrade!

If this is feasible, his strength realm will soon be raised.

But for now, this is just a bold guess.

You have to find a higher-order Stygian Crystal and try it to find out the result.

As soon as he thought of this, Xiao Chen immediately couldn't sit still.

"Teng" ground and stood up from the ground again.

After moving my limbs, I feel a lot more flexible than before. However, it is still in the realm of the early stage of the Iron Corpse.

Only one Immortal Crystal has been refined, although it is still a "King-level Immortal Crystal" that is higher than his own realm, and the improvement in strength is indeed obvious, but if you want to make his realm improve immediately, it is really a fool's dream.

Ordinary corpse cultivators have been living in the abyss for many years, absorbing the extremely rich corpse qi in the surrounding environment all the time, and it will take several years to advance from the early stage to the middle stage of the iron corpse.

Moreover, the higher you go, the more difficult it will be.

Elder Long Jiu has stepped into the path of corpse cultivation for more than a thousand years, but he is only in the early stage of the "Spirit Rank Spirit Corpse".

With such a "spirit corpse" elder, there are only seventeen in the entire Corpse Sect.

More second-generation disciples are still in the realm of "Emperor-level Golden Corpse".

This shows the difficulty of raising the realm of the path of cultivation.

It takes years of patience and perseverance like a water millstone to slowly improve the realm of strength.

Like Xiao Chen, in just half a day, he obviously felt that his strength had increased, and this situation was already against the sky.

What's more, as long as he finds more Stygian Crystals, his realm strength will most likely be like an open hanging, and he will always maintain this momentum of rapid ascension.

In the entire history of the Underworld Corpse Sect for thousands of nearly 10,000 years, there is no precedent for this situation!

With the lingering excitement in his heart, Xiao Chen plunged into the abyss again, swimming towards the charred black floating corpse near his sight.

The Stygian Crystal only condensed in the skull of the corpse that had been forged by the Stygian Fire, and it was only in the area of the pool that had just experienced the Stygian Fire that the floating corpse that had been forged and blackened was his target......
