No matter how indestructible this red cover was, there was no way it could continue to operate after its source of energy was cut off!

Shortly after the two formidable formations were activated, the red energy barrier immediately dissolved, and the Innate Blood Demon Killing Formation's crimson barrier took place instead.

The space here had been isolated by the Innate Blood Demon Killing Formation.

Yang Song smiled and slowly floated into it.

At the core, the two S-rank abyssal demons discovered the abnormal situation on Yang Song's side at the same time, and they looked at him at the same time.

When Yang Song saw this, without much nonsense, he immediately summoned the Blood Demon of the Innate Blood Demon Killing Formation.

Roar…

A dull roar resounded in this isolated crimson atmosphere, and a huge crimson figure with two big horns materialized in front of the two S-rank abyssal demons.

Seeing this gigantic figure, the two abyssal demons were shocked. But before they could do anything, the big figure moved its hand and swooped down at them.

Boom…

At the same time, Yang Song used the Ten Thousand Returning Sword Arts to support from the side.

Bang…

Two great attacks aimed at the two abyssal demons at the same time.

Just then, an even more unexpected thing happened in Yang Song's view. Facing his strong attack, after the two abyssal demons came back to their senses, only one of the two abyssal demons shot back quickly, and the other was still tossing the purple magic ball.

When they fought Yang Song before, they naturally knew that Yang Song was powerful, so now it was absolutely impossible to underestimate the enemy.

Therefore, there was only one explanation for their behavior at this time, and that was their goal, which was so important that they could even give up their lives.

The giant Blood Demon's huge body actually occupied a lot of the space in this red barrier. In front of it, the S-rank abyssal demon, who was originally huge in size, was as small as a bug at this time.

However, that was an S-rank abyssal demon after all!

After a roar, a powerful breath burst out from its body, and then, a large scorpion enveloped its whole body.

Finally, as the surrounding chaotic energy suddenly gathered and exploded, a sturdy energy ray used it as a starting point and burst out.

Regardless of its power, the counter-shock force alone caused the entire large piece of ground in the killing formation space to sink for several meters.

Over there, the powerful blow of the Blood Demon and this abyssal demon had already smashed a piece!

The collision of two powerful forces produced an unexpected shock wave.

However, this shock wave had not yet completely spread outwards, and it was resisted, suppressed, and eliminated by Yang Song's Blue Bolt sword clones.

After eating the full blow of the abyssal demon, the Blood Demon shook its mouth as if it were spiritual, and then, with supreme force, it attacked again!

This was a complete crush.

The full blow of the S-rank abyssal demon just caused a negligible impact on the Blood Demon.

However, facing the second attack of the Blood Demon, the abyssal demon had no plan to give up.

"This is... its Inner Core?"

After seeing the appearance of the light ball slowly emerging from the abyssal demon's head, Yang Song instantly narrowed his eyes and hurriedly stopped the attack.

He had read many history books.

There were records of this situation in history books.

Among the abyssal demons, only the S-rank abyssal demons could summon their Inner Cores.

After being summoned, there was generally only one situation – that was, after the abyssal demon knew that it had no chance of winning, it intended to use its own Inner Core as a super explosive!

The explosion of the S-rank abyssal demon Inner Core was far beyond that of an ordinary nuclear bomb.

In the history of Blue Star, the first person to encounter such a situation was an existence comparable to the top ten powerhouses at that time. When that person was not well prepared, he was blown to pieces by the Inner Core.

"No, this abyssal demon is not going to fight to the death."

Because the other abyssal demon behind it didn't attach any protection measures to it at all, and judging from the fact that it was still tossing the purple magic orb, their purpose had not been achieved.

Sure enough, the abyssal demon threw its Inner Core and hung it over the head of the other abyssal demon.

That Inner Core emitted extremely violent Spiritual Energy.

In the end, beside the other abyssal demon, a barrier that was stronger than the original red energy barrier was formed!

After all of this was done, the abyssal demon lost its Inner Core, and collapsed on the ground, dying, without any fighting power.

"Is this your last resort? It's not bad."

"It's just a pity that you are too careless. The reason why I can open your red energy shield is not because it is not strong enough."

"So what if you create a stronger energy shield at the expense of your own Inner Core?"

"Could it be able to withstand the power of my space?"

Yang Song planned to isolate this Inner Core away, but this time, he planned to use his… storage space instead.

If it was a normal storage space, perhaps this possibility was nonexistent, but this was the storage that the system granted him.

In a short period of several words to himself, Yang Song had already come to the side of the Inner Core, and used the power of the storage space.

Within that friction of time, the Inner Core instantly vanished and was collected by Yang Song's storage space easily.

When the dying abyssal demon saw this, it coughed violently and died right away.

And the final result was the new energy barrier also disappeared along with that.

"Hey, big guy, I don't know if you abyssal demons can understand our human language. If you can understand, how about nodding?" An S-rank Inner Core was easily obtained. Yang Song's mood was infinitely good, so he said in this tone.

There was no response, the abyssal demon didn't even look at his dead companion, and was still tossing the purple magic ball intently.

Yang Song flew around it twice, then looked at the magic ball that had sunk deep underground.

He didn't understand what it was doing at all.

However, it was worth mentioning that because of getting closer, the energy of the space element was also stronger.

The energy of this space element was not only quantitative but also qualitative.

"This is the thing that abyssal demons value so much? It's really extraordinary."

Was it a rare space material?

It was all his own guesses. As for what exactly it was, he would know it after this abyssal demon finished doing its task.

That's right, Yang Song didn't intend to interrupt the abyssal demon's behavior at all.

Why would he interrupt it?

If their purpose had not been achieved, they would definitely act again.

With the lessons learned from this failure, their next action would definitely be larger.

By then, it would be more difficult and catastrophic.

After more than ten minutes, the aura on this abyssal demon's body changed slightly.

Yang Song, who was very sensitive, immediately noticed this change.

It must be known that in the past period of time, the energy flow in and out of this abyssal demon's body was very even.

It seemed that this abyssal demon should have succeeded.

As for why it still maintained its original posture now, Yang Song guessed that it was meant to confuse him.

However, he had been prepared, this abyssal demon could not turn the table around at all, and not to mention… this was the space of the Innate Blood Demon Killing Formation, Yang Song's personal domain.

As expected, in the next moment, the suffocating space element energy suddenly appeared!

At the moment when the elemental energy of this space appeared, a small spatial crack appeared beside the S-rank abyssal demon!

At the same time, a small sphere appeared, and this small sphere was the core of the source of space element energy here.

As soon as it just appeared, it burst out, and it was about to penetrate into the spatial crack.

All this happened so fast, almost in the blink of an eye.

Even if Yang Song was very close, there was no time to step forward to stop that guy at this time.

However, he had been prepared, where did he need to come forward personally at this time?

Innate Mirror Formation!

With a thought, Yang Song controlled the Innate Mirror Formation and made its size reduce.

That's right, Yang Song wanted to use the isolation ability of the Innate Mirror Formation to isolate the abyssal demon and everything around it.

However…

"How can this be?"

In the end, there was an unexpected situation!

Obviously, the space insider the Innate Mirror Formation had been isolated, and the S-rank demon was also trapped inside.

But why was the space element ball still flying towards the spatial crack? 

Yang Song's reaction was also extremely fast, and he flew out immediately, trying to catch that ball.

However, even if his upper-speed limit was so high, even if he used his full strength, it was still too late.

In the end, he could only watch the space element ball touch the spatial crack.

All efforts were wasted.

Why couldn't the isolation function of the Innate Mirror Formation affect this space element ball?

Yes, if it were that simple, how could the abyssal demons spend so much time and effort to get this thing?

If he wanted to blame, he could only blame himself for being too careless... right?

"Hmm?"

However, the sudden change of the next scene made Yang Song stunned.
