The Tiangang Saint Crystal Beast obviously knew something, but was unwilling to tell him.

This also made Shi Feiyu speechless, and his brows gradually furrowed.

Inside the Nine Yin Divine Fire Furnace, the atmosphere instantly became extremely weird. Only the light array at the bottom of the furnace swirled quietly, exuding a brilliant light that was obsessive.

"What do you want?"

After being silent for a long time, Shi Feiyu finally had the intention of compromise.

Seeing this, the Tiangang Sacred Crystal Beast paced back and forth for two steps, and said, "If you want to know the secret of this holy artifact, you must first release the emperor and his fellow clans from this furnace. Secondly, you have to make sure to find a habitat for us as soon as possible. Furthermore, you are to give us a batch of elixirs to nourish our souls to help us recover. ”

Tiangang Saint Crystal Beast said slowly, and when his tone was arrogant, he didn't notice that the other party's face had already sunk.

Just as it was about to make a condition, Shi Feiyu suddenly laughed angrily, grabbed the Saint King Seal and swept towards the bottom of the furnace: "Without you, I can still know the truth." ”

Seeing that he turned his face so quickly, the Tiangang Saint Crystal Beast suddenly breathed sluggishly, and the other demon spirits roared with blood-red eyes, as if they wanted to make a move.

Don't look at the Nine Yin Divine Fire Furnace from the outside, it is only one zhang in size, but the space inside is extremely large, and there is a distance of hundreds of zhang from the bottom of the furnace to the mouth of the furnace.

At this distance, if an attack were launched, hundreds of Wisps would be enough to tear them apart.

But the Tiangang Saint Crystal Beast shook its head and stopped the kind that was about to move.

"Holy Emperor, why don't we leave it behind?"

A demon spirit with a quick temper immediately roared in a deep voice, staring at Shi Feiyu's back was even more ferocious.

"yes, why don't we kill that human kid first, and then find a way to escape later. ”

"I think it's okay, kill him, maybe this Nine Yin Divine Furnace will become ownerless, and he will let us out. ”

Listening to the impatient voices, Tiangang Saint Crystal Beast's eyes sank, and he couldn't help but snort coldly: "If you can, how can this emperor use you to remind you, not to mention that the Nine Yin Divine Furnace has become an ownerless thing, will it let us go, have you forgotten what you experienced at the beginning?"

Speaking of this, the eyes of the Tiangang Saint Crystal Beast were filled with a hint of fear: "Tens of thousands of the same kind are trapped in this furnace, and in the end only you are alive, no one controls the Nine Yin Divine Fire Furnace, and the Divine Fire in the furnace will erupt, do you still want to go back to the old days?"

Many of the demons who said these words fell silent.

Thinking back to the daily fear of the past, it is much better now.

At least the Nine Yin Divine Fire at the bottom of the furnace will not erupt every once in a while, so that they can come out with confidence to breathe.

At this time, the Tiangang Saint Crystal Beast continued to speak: "Even if we can still persist in immortality for ten thousand years, who can guarantee that the next person who controls the Nine Yin Divine Fire Furnace will not be more hateful than him? ”

When the demon spirits heard this, they were all shocked.

Before, they just wanted to kill Shi Feiyu to vent their anger, but they didn't think about it so much.

Now that I think about it, this possibility is extremely high, especially since some refiners will erase their sanity and imprison them for eternity in order to refine divine weapons.

"Although that kid is hateful, he is also a man of his word, and he must have some concerns if he doesn't want to let us go now. ”

After shocking the many demon spirits that were about to move, the Tiangang Saint Crystal Beast sighed and said slowly.

When hundreds of demon spirits heard this, they were all shocked, as if they saw new hope from them.

Putting them down and not mentioning them, Shi Feiyu came to the light array at the bottom of the furnace, pondered for a long time, and finally decided to take a risk.

Under the fluctuation of his mind, the light array suddenly swirled, and the streamer hole sealed in the center of the formation suddenly opened, and a fierce flame was about to surge out.

However, at that moment, he immediately threw the Saint King Seal into it.

As the Saint King Seal was put in, Shi Feiyu immediately closed the entrance to the cave.

I only heard the roar in the center of the light array, and the entire Nine Yin Divine Furnace shook violently, as if it was about to explode.

Shi Feiyu's eyes were firmly fixed on the hole in the center of the light, and his breathing quietly stagnated.

Through the light curtain that sealed the Nine Yin Divine Fire, it could be seen that the Saint King Seal was suffering from the fire attack inside.

With such a fierce fire, I am afraid that even those who have entered the middle stage of the Holy Realm will die immediately if they touch it.

The Saint King Seal, which was only the size of a palm, trembled wildly within the Nine Yin Divine Fire Origin, and the dark gold runes on the surface appeared one after another.

Eventually, the entire seal was transformed into a dark gold color.

And after the complete transformation, there was actually a layer of invisible energy fluctuations on the surface of the Saint King Seal.

As this invisible energy fluctuated on its surface, the countless dark gold runes changed into various forms like living creatures.

Runes are an extremely ancient script, and Shi Feiyu only knows that some of them contain a lot of information, and some of them are used to increase spiritual weapons or their own cultivation.

It's just that the method of identifying runes has long been lost, and even the existence of Motian can't be known.

With a hint of solemnity, waiting quietly for a moment, Shi Feiyu finally saw what he wanted.

In the center of the light array at the bottom of the furnace, the dark gold on the surface of the Saint King's Seal changed for a long time, and suddenly a terrifying suction force emerged, constantly absorbing the Nine Yin Divine Fire.

Visible to the naked eye, a large number of Nine Yin Divine Flames submerged into it and disappeared.

And that absorption took two hours before it finally stopped.

The Seal of the Holy King at this moment is very different from two hours ago.

The dark gold runes that flowed on its surface were long gone, replaced by a brilliant luster.

The splendor seemed to emanate from the inside of the Holy King's seal, shining through the runes in the surrounding space, revealing mystery everywhere.

The most peculiar thing is that this big seal is actually stained in the Nine Yin Divine Fire without any damage.

You must know that the power of the Nine Yin Divine Fire is extremely terrifying, and Shi Feiyu once used his own hands to destroy three people who entered the early stage of the Holy Realm.

It was so powerful that even he felt a palpitation in his heart.

Since the Saint King's Seal was able to persist in such a terrifying flame, it could be seen that this thing was by no means as simple as it was seen now.

Suddenly, remembering what the Tiangang Saint Crystal Beast had said before, Shi Feiyu's eyes gradually narrowed: "Heavenly Demon Clan Holy Relics?"

As for how many holy relics there were in the Heavenly Demon Clan, he didn't know, but Shi Feiyu knew that if the power of this thing was fully displayed, it would have the power to destroy the heavens and the earth.

After the Nine Yin Divine Fire was absorbed in large quantities, it was no longer as fierce as before.

However, as long as the origin of the divine fire is not extinguished, it will not take long for this ferocity to recover.

His mind moved slightly, and the light array suddenly opened, and Shi Feiyu immediately took out the Saint King Seal from it.

When the Saint King Seal entered his hand, his face changed suddenly.

This great seal is like the dawn sun, with the heat of destruction.

With just a slight touch of the palm, the flesh and skin of the palm disappeared instantly.

If it hadn't been withdrawn fast enough, I believe that the entire palm would have turned into nothingness in a short instant.

With a wave of his hand to close the light array, Shi Feiyu took a breath of cool air, and waited until the Saint King Seal gradually cooled down before daring to step forward.

The cooled Saint King Seal returned to its original appearance, and it was as black as before.

But under the darkness, there was a faint brilliant glitter.

Although it was only a flash, Shi Feiyu still felt that the Saint King Seal had become different from before.

Especially in his hand, the weight was too much for him to bear.

This is still not used, if the majestic divine soul is poured in, it is believed that this great seal will burst out with even more terrifying power.

Haha laughed a few times, only to see his eyes sweep, and found that many demon spirits not far away were staring at him, so he suddenly raised his hand to knock out the Saint King Seal.

The pitch-black seal shook suddenly, then rose against the storm, turned into a huge existence, and left with terrifying coercion.

Seeing this, many demon spirits immediately fell into a panic.

The roars, reprimands, shouts, and roars rang out in one piece, and the Nine Yin Divine Fire Furnace immediately became noisy.

However, just as they were fully prepared and were about to regret this attack, the Saint King's Seal suddenly fell from mid-air with a soft bang and smashed against the furnace wall.

At that moment, all the sounds disappeared abruptly, and only this sound echoed in the Nine Yin Divine Fire Furnace, lingering for a long time.

And Shi Feiyu's face became a little ugly because of this.

It wasn't until a moment later that he reacted, and then muttered to himself, "Is it self-defeating?"

The use of the Saint King Seal was extraordinary, several times stronger than before.

But halfway through, that kind of coercion seemed to suddenly disappear without a trace.

Not only that, Shi Feiyu even found that the connection between this great seal and himself was inexplicably severed.

Muttering to himself, as if he suddenly woke up, he saw him rush forward with an arrow step and take back the Saint King Seal.

At the same time as putting away the Saint King Seal, Shi Feiyu also retreated sharply, and immediately stood in front of the light array at the bottom of the furnace, his eyes showing vigilance.

Looking at his vigilant appearance, many demon spirits were full of anger.

"Boy, what were you going to do just now?"

There was a demon spirit that couldn't get hot after all, and walked forward with a wild drink.

And the other demon spirits are also eyeing each other, pressing forward step by step.

The atmosphere was tense to the extreme, and Shi Feiyu even felt cold sweat seeping into his palm.

At the last moment, the majestic voice of the Tiangang Saint Crystal Beast suddenly came, breaking the solidification: "Let him go." ”

As its voice rang out, hundreds of wraiths immediately parted to the sides.

Seeing this, Shi Feiyu didn't dare to stay for a long time, and rushed out with a shake of his body.

However, the moment he rushed out of the furnace, he grabbed a jade bottle and threw it at the Tiangang Saint Crystal Beast: "Thank you." ”

Looking at the jade bottle he left behind, the claws of the Tiangang Saint Crystal Beast trembled slightly, and he immediately smashed the jade bottle with one claw without hesitation, took a greedy breath, and said, "Soul Containing Pill." ”

What Shi Feiyu left behind was indeed the Soul Containing Pill it wanted.

This elixir is not only useful for cultivators, but also very beneficial for demon spirits like the Tiangang Saint Crystal Beast.

At the very least, it can restore its damaged Wisps a little.

"Holy Emperor......"

In addition, those demon spirits also saw the Soul Containing Pill, and a few of them who had a good relationship with them immediately came over, and their tone was slightly flattering.

Unexpectedly, before they could speak, the Tiangang Saint Crystal Beast trembled and suddenly swallowed the Soul Containing Pill.

At that look, many of the demon spirits who saw it rolled their eyes......
