The old man with a dry face is the demon giant emperor of the evil demon clan outside the sky.

The demon giant emperor is named Ula.

He is in charge of all demons outside the sky, billions of demons, cruel, bloodthirsty, and the magic of demons is unpredictable.

In the space plane of demons outside the sky, all demon races have conquered him.

But his ambitions were not extinguished, and he placed his next goal in the prehistoric world of the human race.

The human race cultivators are very powerful, and the human race lives in the prehistoric world with superior resources for cultivating immortals. Unlike the plane world of demons outside the sky, which is over-propagated and consumed the huge population of demons. Moreover, the plane world of demons outside the sky is also poor, mountains and rivers, and the environment is extremely harsh.

Therefore, the demon giant emperor Ula has long been drooling at the prehistoric world where the human race is as picturesque as a fairyland.

However, the plane of the demon world outside the sky, the space channel leading to the prehistoric world of the human race was sealed, blocking his ambitions.

Although his cultivation strength has reached the ninth level of the Immortal Emperor and is very close to the strength of the gods, the sealing formation power of this space channel leading to the prehistoric world was sealed by the four ancient immortal emperors using their lives and cultivation magic power.

Even if the demon giant emperor has the ninth level of strength, it is impossible to break the seal formation power formed by the four ancient immortal emperors.

However, over the past hundreds of thousands of years, the plane world of demons outside the sky has been replaced by several demon giant emperors. These demon giant emperors have never given up on their plans to invade the prehistoric world for hundreds of thousands of years. They have continuously attacked the power of the sealed space channel formation.

It was through these former demon giant emperors who attacked the formation power of the sealing space channel that when Ula became the demon giant queen, many formation cracks had appeared in the sealing formation power of the space channel, and the sealing formation was moderately damaged.

This is also the reason why Lin Fei discovered that the sealing power of the space channel was mixed with countless subtle black gas.

And over the past few days, after the erosion and destruction of the demon giant emperor Ula demon magic, the space channel sealing formation has reached the edge of collapse.

It can be said that the sealing power of the space channel seen from the prehistoric world is just a mere appearance, and in fact, the inside of the formation has long been completely destroyed.

Of course, even if the seal formation is about to be destroyed, without the strength of an immortal emperor like Lin Fei, there is no way to see the crisis in it.

This is also the Supreme Elders and Masters of the Four Holy Land Immortal Sects, who sat on the ground at the Fengxiantai without any notice. Their cultivation strength cannot find any problem with the sealed space channel formation.

"Father, the formation that seals the space channel has reached the edge of collapse. Just one knife can be cut open. The world of the prehistoric world is our demons and evil clan fat!" At this moment, a middle-aged man standing behind the demon giant emperor, with silver armor, his face as dry as a mummy, and his skin as white as a zombie, said gloomy and proudly.

This man with a white face as a zombie, was Wucha, the eldest son of the demon giant emperor Ula.

The other three Silver Armors, who also have ferocious faces and obvious demon characteristics, are the other three sons of the demon giant emperor Ula: Wuba, Wuha, and Wucha.

Although Wucha, Wuba, Wuha and Wucha are not as strong as the ninth level of the demon giant emperor Wula Immortal Emperor, their cultivation strength has also reached the second, third, fourth and fifth levels of the Immortal Emperor.

But in the world of demons outside the sky, the four famous demon kings.

"My four sons, don't worry, you all see that the human race is going to hold a competition for the prehistoric world, and have summoned all the immortals in the prehistoric world to come. At that time, we can destroy the human race in one fell swoop, make the prehistoric world a paradise for us, and trampling the human race slaves under our feet." The Demon King's eyes flashed with bloodthirsty light, and swept to the sons of the four demon kings.

"And although the formation power of the sealing space channel is about to collapse, there is still a core formation node that needs to be broken. I believe this is the formation core formed by the four ancient immortal emperors and immortal bones of the human race."

Speaking of this, the Demon King's deep and sharp eyes suddenly looked into the depths of the sealed space channel formation, where there was extremely powerful and magnificent immortal magic power, and you could vaguely see the shadows of several skeletons posing in strange postures.

The Demon King had already guessed that these are the four ancient immortal emperors of the human race. After the destruction of form, they still left behind immortal bones and formed a core node of the formation, which could still support the entire formation.

Although only these four ancient immortal emperors and immortal bones are left to form the final node of the formation, it is also the most powerful formation node.

"My father was thinking about Zhou Xiang. The Supreme Elders of the Human Clan Immortal Sect just now, but after fifteen days, the Great Wind Competition officially began. By then, the immortal cultivators in the prehistoric world gathered here from all directions, and we can destroy the human race in one fell swoop!" Wucha's eyes also had an unconcealed excitement.

Wuba, Wuha, and Wucha also smiled cruelly and sinisterly: "The human women stayed, and became slaves from our demons and evil clans to serve us, and the man did not stay, hehe..."

"Ha ha……"

The demon giant emperor Ula said solemnly: "Although there is only the last node left in this seal formation, I am afraid I need to exhaust all my strength to use the Demon Emperor sword in my hand to blast open the formation node."

"But after I blast open the formation node, I will need at least ten days to re-train my cultivation before I can restore my original state of strength."

Wucha said to his father: "Father, please don't worry. After you blast the formation, we four brothers will lead the army of demons to conquer the prehistoric world. You can go back to the Demon Emperor Palace to practice and restore your skills first, and wait for us to bring you the best news to conquer the prehistoric world!"

The Demon King showed a gloomy smile on his face and said with satisfaction: "Well, I feel relieved with you four brothers!"

Then, his eyes looked at the other side of the space passage, and looked at the tens of thousands of immortal cultivators on the Fengxiantai and the surrounding mountains. He said in a cold voice: "Soon, you will tremble under the army of demons and become bloody and fleshy mud under our army of demons."

In the vast world of prehistoric world, the four wildernesses in the east, west, south, north and north, all the cultivators learned about the news of the prehistoric competition. The prehistoric competition is the most important event for all the prehistoric practitioners.

Because those who participated in the Great Wind Competition were all powerful immortals and powerful, even if they went to watch it, it would be a visual feast, let alone a glimpse of the style of the highest figures in the Great Wind, and they could also understand many of the wonderful immortal techniques they would never learn and see in their lifetime.

Therefore, when we learned that the Great Prehistoric Competition will officially begin in fifteen days, almost all the cultivators in the prehistoric world are preparing to come to Tongtian Realm to watch the competition, and some are already on the way to Tongtian Realm...

The formation blocked the lake within a radius of hundreds of miles. Lin Fei, who was practicing on Qixian Island, also ushered in a new breakthrough...
