Ancient palaces stood in front of him, Nie Feng walked towards those palaces, and found that this was an ancient city, and he didn't know how many long years had passed.

"Whoosh!"

In the depths of the ancient city, suddenly, a powerful realm slave rushed out, like a dead corpse, without the slightest breath of life on his body, but extremely powerful.

Nie Feng's eyes froze, after coming to the Eternal Realm, it was the first time he had encountered a boundary slave, and he thought that only the three thousand worlds would appear in the realm slave.

"Roar!"

The Realm Slave let out a roar that didn't sound like a human voice at all, but the roar of a beast.

Nie Feng's eyes froze, and he sacrificed the Xuanyuan Divine Sword, blooming with a brilliant sword light, cutting the realm slave in two.

In the ancient city, there were a lot of boundary slaves, Nie Feng was surprised in his heart, only to see that in the depths of the ancient city, there were constantly boundary slaves rushing out, they were much stronger than those realm slaves in the eternal trial ground, and all of them cultivated to the Saint Emperor realm.

Of course, the realm slaves that Nie Feng has encountered so far have the highest cultivation level of the Saint Emperor First Realm, and there is no existence that has surpassed the Saint Emperor Dual Realm.

"Boom!"

In the ancient city, the sound of an amazing battle broke out, and Nie Feng fought fiercely with the Boundary Slaves, killing the three Boundary Slaves in the blink of an eye.

There are more realm slaves in the sky, and all of them are in the Saint Emperor realm.

The Realm Slave has lost consciousness and has no soul at all, but only exists in the form of a physical body, which is equivalent to the walking dead.

Normally, the realm slaves of the Holy Emperor First Heavy Realm could often suppress human cultivators, because they didn't feel pain at all.

However, the strength shown by Nie Feng was extremely amazing, and he slashed the realm slaves between his hands, and he did not have the slightest fancy.

The surrounding surprised eyes were projected, looking at Nie Feng, they all understood Nie Feng's strength, especially Zhang Lin, his face became extremely solemn, although he was a Saint Emperor Dual Realm, but in terms of talent, he was far inferior to Nie Feng.

With a "bang", the sword qi roared, and Tuoba Sword struck, sweeping with a sword, containing the power of the origin of the sword, and killed the five realm slaves in the blink of an eye.

Tuoba Sword shot, shocking the Quartet, everyone was terrified, the power of the origin of the sword, what a terrifying power, Tuoba Sword is worthy of being the generation of Tianjiao of the Wind Thunder Sect.

Nie Feng just glanced at Tuoba Jian lightly, and didn't continue to pay attention, his eyes looked deeper into the ancient city, where there seemed to be thunder flashing, and the sound of the wind howling.

"Whoosh!"

In the sky, more realm slaves came to the sky, their eyes were extremely empty, and their bodies were full of evil aura.

Nie Feng wondered in his heart, in the past, in the Three Thousand Great Worlds, there were Boundary Slaves, and that was because the cultivators in the Three Thousand Worlds could not go to the Eternal Realm, and when they were training in the Eternal Trial Ground, they became Boundary Slaves.

But now it seems that there are also Boundary Slaves in the Eternal Kingdom, which has to be thought about.

Who is behind the existence of the Boundary Slave?

Nie Feng didn't know that the problem he was worried about now was not behind the scenes, in the ancient city, more and more realm slaves rushed in, and the number exceeded hundreds, and it was difficult for him to break through.

"Whew!"

The Xuanyuan Divine Sword slashed out in the air and killed a realm slave, but there were many more realm slaves rushing to kill, and those realm slaves did not feel pain, as if they were abiding by the same principle of action, that is, to kill those who broke into the ancient city.

Nie Feng now understands a little that the white bones in those cities may have died in the hands of the boundary slaves.

Suddenly, Nie Feng's pupils contracted, and among the hundreds of realm slaves, he found a familiar existence.

"Could it be the Xuanyuan Holy Emperor?!"

Nie Feng was horrified in his heart, he had seen the statue of Xuanyuan Holy Emperor in the Three Thousand Worlds before, which was very similar to the current Realm Slave.

"Buzz!"

The Xuanyuan Excalibur suddenly let out a violent buzzing sound, as if it sensed something.

In the past, Xuanyuan Divine Sword had been following the Xuanyuan Holy Emperor, and he was very familiar with the Xuanyuan Holy Emperor.

Nie Feng sent out a divine thought, communicating with the sword spirit of the Xuanyuan Divine Sword, and the next moment, Nie Feng understood that the realm slave in front of him was the Xuanyuan Holy Emperor who was famous for eternity!

In the Eternal Realm, the Xuanyuan Holy Emperor may not be nothing, but in the Three Thousand Worlds, the Xuanyuan Holy Emperor is a legend and a myth.

Nie Feng knew very well what the Xuanyuan Holy Emperor represented, he could be said to be the most powerful figure in the three thousand worlds for millions of years, relying on his own strength to achieve the position of the Holy Emperor.

In the three thousand worlds where the power of faith is barren, the difficulty of achieving the Saint Emperor realm can be imagined, and the Xuanyuan Saint Emperor relied on the talent that shocked the eons to be born into the Saint Emperor realm and ascended to the eternal realm.

It's just that outsiders don't know, thinking that Xuanyuan Holy Emperor has infinite scenery, but they didn't expect that after coming to the eternal realm, Xuanyuan Holy Emperor became a realm slave.

Nie Feng sighed in his heart, he had the intention to rescue the Xuanyuan Holy Emperor, after all, they were all from the Three Thousand Worlds.

It's just that now Nie Feng can't do anything, once he becomes a realm slave, it means that the divine soul collapses, leaving only the physical body and becoming a walking corpse.

To be precise, the previous Xuanyuan Saint Emperor had already fallen, and now all that remains is the walking dead, not the Xuanyuan Saint Emperor at all.

"Could it be that my cultivators of the Three Thousand Great Worlds are so unbearable? Who is it that has turned them into realm slaves?"

Nie Feng felt anger in his heart, in the Eternal Trial Ground, he saw many realm slaves, and in the eternal realm, there were also realm slaves, and it seemed that those realm slaves were very likely to be ascended in the three thousand worlds!

"Whew!"

The sword qi roared, and Nie Feng held the Xuanyuan Divine Sword in his hand and killed the realm slave transformed by the Xuanyuan Holy Emperor.

In Nie Feng's heart, Xuanyuan Holy Emperor is the pride of the three thousand worlds, belonging to the legendary figures, Nie Feng does not want to see Xuanyuan Holy Emperor fall to this, after death, even the physical body will be humiliated and become a slave.

"Phew!"

The sword qi was vertical and horizontal, and Nie Feng slashed the realm slave transformed by the Xuanyuan Holy Emperor with one sword!

A cloud of flesh and blood exploded, and the body of the Xuanyuan Holy Emperor collapsed, becoming the dust of history.

Nie Feng sighed in his heart, if the Xuanyuan Holy Emperor had knowledge, he should also thank Nie Feng for helping him completely liberate.

"Kill!"

In the crowd, there was an amazing sound of fighting, and the disciples of the Inner Sect of the Wind Thunder Sect were all red-eyed, under the siege of hundreds of boundary slaves, they had to go all out, otherwise, they would be like those realm slaves, and they would become walking corpses.

Nie Feng's face was solemn, he controlled the Xuanyuan Divine Sword, and rose to the sky, and there were small stones and moonlight wheels beside him, blooming with brilliant light, guarding Nie Feng, killing the realm slaves all the way, and breaking out of the encirclement.

With three holy weapons in his hand, Nie Feng's combat power is unparalleled, and in the blink of an eye, he has already broken out of the encirclement, and in front of him, there is an iron chain bridge suspended, and at the other end of the chain bridge, there is a thunder pool!

In the thunder pool, the thunder and lightning were raging, and the wind was howling in the sky, and the scene was extremely terrifying.

The power of the origin of wind and thunder is in that thunder pool, and if you accept the baptism of the thunder pool, you will be reborn and master the powerful power of the origin of wind and thunder!
