The Divine Dragon's Breath could not be used in the soil layer, and even the Demon Sword was not easy to use, so Lin Yun could only speed up and chase after the naked man.

However, the naked man is very proficient in the earth element, and after he touches the soil, he can temporarily liquefy the soil, so the movement speed in the soil is very fast, which is far beyond Lin Yun's reach.

Lin Yun had no choice but to take out one of the killer weapons, the Blood Spiral Dart.

After injecting Lin Yun's vitality, the bloody spiral dart spun at a high speed in an instant, and then cut through the soil like cutting tofu slag, and chased straight towards the naked man.

Seeing this, the naked man hurriedly drilled deeper into the ground, and kept drilling down several kilometers into the ground, and actually escaped the farthest control distance of the bloody spiral dart.

Lin Yun had no choice but to follow the pursuit, but no matter how much he chased, he couldn't catch up with the naked man.

With the speed at which the naked man was moving underground, it was easy to get rid of Lin Yun, but he didn't shake off Lin Yun and run away.

Whenever Lin Yun was about to be thrown away by him, he would stop and wait for Lin Yun for a while. And when he Lin Yun was about to catch up with him, he immediately accelerated to throw Lin Yun away, playing Lin Yun like flying a kite.

Lin Yun soon realized that something was wrong, the other party was just dodging at first, and he didn't intend to confront him head-on.

He had no intention of fighting him, and he had no intention of running away, it was obvious that he was stalling for time.

But why did he procrastinate?

And who does he give time?

A white light suddenly flashed in Lin Yun's mind, and he suddenly understood everything.

……

A quarter of an hour ago, the Southern Xia Fortress.

With a terrible scream, the hacker emperor who was grabbed by Ouyang Xiu's head rolled his eyes and lost his reaction directly.

Ouyang Xiu threw the Hacker Emperor directly to the ground like garbage, and then burst out with the vitality of the waves, condensing a brain-shaped martial soul behind him.

This martial soul is obviously the martial soul of the Hacker Emperor!

After condensing the martial soul of the Hacker Emperor, Ouyang Xiu turned to look at the people in the distance.

Emperor Axiba, Emperor Wu of Han, Emperor Nanchang, and the martial arts powerhouses of the empires were all frozen in place and unable to move the moment Ouyang Xiu saw it.

The hundreds of thousands of soldiers who charged towards Ouyang Xiu were also frozen in place like petrified, unable to move even a finger.

The Polish Emperor, the Cuban Emperor, the Benganon Emperor, and the Yanxue Emperor, who were seriously injured, had just given themselves the healing pill and were about to stand up again, but they were only glanced at by Ouyang Xiu carelessly, and they were also frozen in place and unable to move.

"My body...... I can't move......" said the Polish Emperor with a look of despair.

"Damn...... It's the martial soul ability of the Hacker Emperor! We're all under control now......" said the Cuban Emperor through gritted teeth.

"Control hundreds of thousands of people at the same time...... The Hacker Emperor's martial soul ability can be so powerful when he uses it! The non-emperor of Benganon said in disbelief.

After seeing that everyone couldn't move, Ouyang Xiu nodded with satisfaction: "Well, this martial soul ability is quite useful, but I don't know if it will work for Lin Yun." ”

"With your little mental power, you also want to control my master? Dream on! Yan Long burst out at this time, and instantly burst out with overwhelming heat.

Peng ——!

With an earth-shattering and terrifying loud noise, a blue pillar of fire with a diameter of ten meters instantly rushed up thousands of meters high, directly dispersing the clouds in the sky.

Seeing this shocking picture, everyone present showed an expression of disbelief.

"Good...... What a powerful fire elemental energy! It's as terrifying as a volcanic eruption! ”

"What the hell did he do? How did it suddenly become so powerful? ”

For a while, everyone was shocked by Yan Long's strength. And the most shocking of them is Prince Nangong.

Prince Nangong has fought side by side with Yan Long the most times, and he has spent the longest time together in the past two months, so he is very clear about Yan Long's strength.

Although Yan Long's strength was stronger than him, it was only at the level of a first-level Martial Emperor.

And Yan Long's aura at this time has become even stronger than that of a third-level martial emperor, although it can't catch up with Ouyang Xiu, it's not far behind.

Ouyang Xiu wasn't surprised, he obviously knew what was going on: "Burned the demon core in your body?" You're going to die. ”

Hearing Ouyang Xiu's words, Prince Nangong's heart shook violently, and he immediately looked at Yanlong with a surprised gaze.

Prince Nangong had heard Lin Yun say that the body structure of the creatures in the Demon Realm was different from the creatures in the Tianwu Continent. The creatures of the Demon Realm do not have a dantian in their bodies, but they do have a demon core that stores demonic energy.

The demon core is the source of all energy, and its effect is equivalent to that of a human dantian. But unlike the human dantian, the demon core of the demon realm creatures can be burned.

In the few minutes that the demon core burns, the strength of the demon realm creatures will increase dozens of times.

And once the demon core is burned out, the death period of the demon creatures will come, and even the power of the divine domain will not be able to save them.

It can be said that the demon core is equivalent to the heart of the demon creatures, and even more important than the status of the heart.

If the demon creatures don't have a heart, they can also consume the energy of the demon core and make the heart grow again. And if there is no demon core, then the demon creatures will really have no power to return to the sky.

Although Yanlong can only be regarded as half of the demon realm creatures, the importance of the demon core to him cannot be banned. And now he chooses to burn his demon core, which is equivalent to giving his life.

Thinking of this, Nangong couldn't help clenching his fists and looked at Yan Long's gaze, full of regret and sadness.

If you want to say who has the deepest bond with Yanlong other than Lin Yun, the answer is undoubtedly Prince Nangong. He has been with Yanlong for the longest time and has fought side by side the most, so the bond is naturally the deepest.

As soon as he thought that Yan Long was about to be sacrificed, he felt unspeakably uncomfortable in his heart.

Compared with Prince Nangong's grief, Yanlong himself is much more free, and he is obviously ready to die.

"Even if I die, I'll drag you to hell with me!" The flame dragon burst into shouts and rushed towards Ouyang Xiu, the scorching blue flames enveloped his whole body, forming a blue fireball with a diameter of tens of meters, like a blue miniature sun, unstoppably blasting towards Ouyang Xiu.

Ouyang Xiu raised his right hand and aimed his palm at the blue fireball: "Don't be naïve, do you really think that if you do this, you will be able to die with me?" ”

"I can absorb all the elemental power, no matter how strong your flame attack is, it won't be able to hurt me a single hair!"

As soon as Ouyang Xiu's words fell, the blue fireball hit his palm.

The huge fireball with a diameter of tens of meters was absorbed by Ouyang Xiu's palm in an instant, as if it had been sucked into a black hole.
