Chapter 619: Fighting against the Great Sage

While telling Zhang Xiaofan the reason for the incident, Xiao Yun led him to rush out of the battlefield of the five tribes.

However, the exit on the side of Tiandi City could not be taken, so this time they chose to go to the side of the Billions of Mountains of the Demon Clan.

"Brother Xiao, the demon clan and our human race are mortal enemies. Is it safe for us to go this way?" Zhang Xiaofan said with some concern.

"Swish!"

Xiao Yun killed the practitioners from the other world who were chasing him with a sword, and looked at their fallen bodies, and said coldly: "Do you think there is only one space channel on the side of Tiandi City? This time the other world has a plan. Since there is a space channel on the side of Tiandi City, there will naturally be one on the side of the demon clan."

In fact, Xiao Yun has already sensed that there is a fierce battle on the side of Billions of Mountains, which is not inferior to that on the side of Tiandi City.

Obviously, Honghuang has opened more than one cross-border space channel this time.

"I really don't know how to get through this difficulty..."

Xiao Yun's eyes are full of worry.

Although judging from the development of later generations, the human race should have won the final victory.

But now that the Emperor of Heaven and the Dragon King have been suppressed, and the prehistoric world is invading in large numbers, Xiao Yun can hardly imagine how the human race won the victory.

"I didn't expect that this small place actually hides a top-notch immortal!"

A sneer suddenly came from the sky.

Then, a huge bird swooped down, flapping its huge wings, rolling up a strong wind, covering the sky and the sun.

The fierce murderous aura shocked Xiao Yun and Zhang Xiaofan.

"It's the demon race!" Zhang Xiaofan was shocked.

Xiao Yun shook his head and said, "It's not the demon race in our world, but the demon race in another world."

He knew that there were also demon races in the prehistoric world, but after the war between witches and demons, didn't the demon race decline? They were often hunted down by the human race, and this time they could actually invade.

"Boom!"

The bird stretched out its sharp claws, collided with Xiao Yun's immortal sword, and burst out a series of brilliant lights.

The powerful force was transmitted through the immortal sword, which shocked Xiao Yun all over.

"The peak of the great sage!"

Xiao Yun's pupils shrank.

He didn't expect that this bird was actually a great sage at the peak. Although it was not worth mentioning in the prehistoric world, it was definitely a super strong man standing at the peak in their side.

And his current strength could not defeat the great sage at the peak.

Unless Xiao Yun could become a sage.

However, in this era, Xiao Yun could not entrust his way to the way of heaven, that is to say, he could not become a sage in this era.

Half-sage was already the limit that Xiao Yun could achieve in this era.

"You go first, I'll hold it back first, and then I'll come!" Xiao Yun said to Zhang Xiaofan while blocking the bird in front of him.

"Brother Xiao——" Zhang Xiaofan's face was full of anxiety and worry.

"Go!" Xiao Yun shouted, and sacrificed five holy swords in a row, forming a five-element sword formation, trapping the bird in front of him.

Countless sword qi and sword light strangled the bird inside, and then the demons in the prehistoric world were the same as the demons in this world, and their bodies were very strong.

The powerful fighting power of the peak level of the Great Sage made Xiao Yun's attack ineffective.

"An ant that has not become an immortal can actually exert such a powerful force. The human race in your world is really terrible!"

The bird stared at Xiao Yun with sharp eyes, and suddenly opened its mouth, shaking the world with a long roar.

Then, the feathers on its body shot out, like a sharp sword, smashing the five elements sword formation like a dead tree and rotten wood.

"Bang bang bang!" Four of Xiao Yun's five holy swords were broken on the spot, leaving only the last immortal sword dim and was quickly taken back by him.

"Damn it!"

Looking at the broken holy swords in the air, Xiao Yun felt distressed. These were the holy swords he had collected with great difficulty, which just corresponded to the five elements sword formation.

Unexpectedly, they were all destroyed in this battle.

However, the immortal sword obtained from the prehistoric strongman could still hold up.

It must be said that the level of refining in the prehistoric world is more powerful.

"Little bug, it's time to end!"

The bird rushed out of the Five Elements Sword Formation, and enveloped Xiao Yun with a sharp murderous intent. Its sharp eyes like an eagle were like two divine swords.

Although the peak level of the Great Sage is still at the Great Sage level, it is obviously too much higher than the Great Sage level and is not at the same level at all.

Xiao Yun's combat power at this time is considered top-notch even among the Great Sages, but it is still far inferior to the peak level of the Great Sage.

Being able to hold the bird for a while is already very impressive.

"The extreme heavenly tribulation!"

"The heavenly tribulation is coming!"

Xiao Yun suddenly roared.

The bird was stunned. Heavenly tribulation? This guy can also summon the heavenly tribulation to come? Impossible!

However, at this moment, Xiao Yun's chaotic domain enveloped the world, summoning majestic dark clouds to imitate the tribulation clouds, and imitated the power of heaven and earth to sweep over.

Then the thunder tribulation stored in the chaotic domain was released, and it struck at himself and the bird.

"How is it possible?"

"He actually summoned the Heavenly Tribulation!"

Fei Qin was so scared that his eyes almost popped out. In their prehistoric world, whether it was the demon race or the human cultivators, everyone feared the Heavenly Tribulation the most.

At this time, seeing the Heavenly Tribulation coming, Fei Qin did not doubt that it was fake at all. After all, the breath of the Thunder Tribulation could not deceive it. When it survived the Tribulation of Transformation, it was too familiar with the breath of the Thunder Tribulation.

"Boy, you have the guts-"

The bird cursed secretly, and then fled quickly, out of the coverage of the heavenly tribulation. In fact, this was only the coverage of the chaotic realm.

Even at this time, it did not doubt that the heavenly tribulation was fake.

First of all, the power of this thunder tribulation originally came from the heavenly tribulation, and it was genuine.

Secondly, Xiao Yun's cultivation was half-saint, corresponding to the half-immortal in the prehistoric world, and it was indeed at the critical moment of transcending the tribulation and becoming an immortal, so it was normal to attract the heavenly tribulation.

With these two points, the bird had no doubts.

After all, it didn't want to die under the heavenly tribulation with a little bug from another world.

Once it entered the heavenly tribulation, the power of the heavenly tribulation would definitely rise to the peak of the great saint, enough to threaten it.

"Little bug, when you survive the heavenly tribulation, you will only have half your life left, and it will be easy to kill you at that time." The bird stopped where it was, staring at the heavenly tribulation in front of it with a sneer on his face.

However, at this moment, Xiao Yun fled to the exit of the demon clan with the tribulation cloud.

As for those thunder tribulations, they were originally subdued by him, and now they bombarded him, so they couldn't hurt him at all.

After a while, Xiao Yun distanced himself from the bird.

"This guy actually used his body to resist the heavenly tribulation!" The bird looked at Xiao Yun who was constantly bombarded by the thunder tribulation with a shocked face, and was very shocked in his heart.

However, the better Xiao Yun's talent, the more it wanted to kill Xiao Yun, so it followed the heavenly tribulation closely.
