As soon as Tianwei came out, he was amazing, and he withdrew from Hongjun, who was more than 100,000 miles away, and Fu Xi and the others all took a breath of cool air.

"This ...... What is this?" was shocked all over the world, looking at the overwhelming Tianwei, and his speech was not smooth.

"I have a feeling of facing the heavens, depressed, heavy!" Aoshi said.

The primordial was already in a cold sweat, and his heart trembled, this was the power of heaven, how could Si Cheng make such a move.

Outside the Ancient Tower, the First Demon also frowned, and then his expression froze.

"Tianwei?"

This is not an ordinary Tianwei, let alone the Tianwei of the earth or any planet, but the Tianwei of the starry sky, which is even more powerful.

"Boom ......"

Tianwei roared past, directly covering the broadsword, at this moment, no matter how powerful the broadsword was, it was also directly defeated in front of Tianwei, and after an instant, the starry sky dissipated.

And Tianwei is not over, at this moment, the entire galaxy is overwhelming, and it is spreading towards the Desolate Ancient Tower, the First Demon and all directions.

"Ahh......h

All of a sudden, there were bursts of screams in the distance, and under the vast heavenly might, some Immortal King Realm and Immortal Emperor Realm were all wiped out in an instant.

"It's not good, get back!"

Hongjun and the others, who were more than 100,000 miles away, also retreated again, 200,000 miles, 300,000 miles, and did not stop until 500,000 miles.

"Sharpen the fourth style!"

Seeing this scene, the first demon's face also changed, and he suddenly condensed into a big knife in the air again, this big sword was unprecedentedly large, and the giant sword that Si Cheng had used before was as small as an embroidery needle.

At this moment, the entire galaxy was completely covered by the big sword, which was terrifying.

"Bang!"

There was an earth-shattering bang, deafening, and a terrifying and monstrous energy storm was directly formed, sweeping everything.

"Poof!"

Si Cheng was hit by the energy storm, and a mouthful of blood spurted out directly, and his entire body flew upside down crazily, until it was thousands of miles away, and then stopped.

At this moment, Si Cheng's clothes were ragged, his hair was scattered, and his chest was even more red.

"Ahem!" Si Cheng suppressed the injuries in his body and spat out a few mouthfuls of blood again.

And the first demon on the other side is much better than Si Cheng, he is a god and demon, but also the first demon, the ancestor of the god and demon clan, and the most important thing is that he is beyond the existence of the immortal zun, not only is his strength extremely strong, but his physical body is also extremely strong.

Although this level of storm can also cause him a certain amount of damage, it is negligible to him.

At this time, he looked coldly at Si Cheng, who was thousands of miles away, his face was cold, thousands of miles, for the battlefield between the Immortal Venerable Realm, it was nothing at all, and even the range of tens of thousands of miles was normal.

"Okay! Very good! Tianwei! It's just a pity that your Tianwei strength is too weak, although you are still not my opponent, but congratulations, you have angered me!" The First Demon's eyes showed a light of anger, and at this moment he was really enraged.

"Hehe, is it?At least with Tianwei, you can't help me!" Si Cheng chuckled. At this moment, he finally knew that the power of the First Demon was not comparable to him now.

With his current self, if he wants to defeat the first demon or even kill, he can only rely on Tianwei, but the way of heaven has only comprehended a little bit, and it is far away from Xiaocheng, and its power is naturally greatly reduced.

If you want to defeat the First Demon, there are only two possibilities, one is to continue to cultivate, and when you also become an existence that surpasses the Immortal Venerable, there is naturally no problem.

The second nature is to comprehend the way of heaven to be completed, and even to be consummated, and at that time, with the power of heaven alone, it can also defeat the first demon, and even kill.

As for now, don't even think about it, you can only rely on Tianwei not to die at the hands of the First Demon, and nothing else can be done.

Thinking of this, Si Cheng sighed slightly, in general, his strength is still too low, but if he wants to surpass Immortal Venerable, it is not easy to talk about, at least the power of the origin is a heavenly moat, which cannot be surpassed.

"Hehe, yes? You have to know what will happen if you provoke me. The First Demon's face was gloomy, and then a large knife appeared in his hand.

The big knife just now was just a condensation of the qi of the immortals and demons, but now it is a real big knife, the blade is two meters long and half a meter wide.

"Slay the dragon! I was originally going to deal with the coiling dragon, but since you want to die, I will take your sacrificial knife first!"

"What, dragon slayer, is it a dragon slayer?"

Si Cheng's heart moved, he had heard of the Dragon Slaying Knife not long after he entered the Kunlun Mountain Sect, and even saw it in person when he participated in the new ** competition, but it was completely different from what it looks like now.

"Are you a dragon slaying knife, a dragon slaying knife in the earth?" Si Cheng asked.

"Oh, you know, are you from Earth?" the First Demon was obviously stunned, and looked at Si Cheng in some surprise.

"Yes! When I was very weak, I had heard of the Dragon Slaying Knife, and the Dragon Slayer Knife was now intolerable. Si Cheng said, there is nothing that cannot be admitted.

That's because the earth's Heavenly Dao is too weak, and the Source Weapon has the power to threaten him, so it naturally can't tolerate it. ”

"What? Source Device!" Si Cheng was horrified in his heart, the Dragon Slayer Knife turned out to be a source device, and the Five Elements Order in Si Cheng's storage bag was a half-source device, but compared to the real source device, it was undoubtedly too much worse.

Because the source device is conceived by heaven and earth and formed naturally, while the semi-source device is artificially created and refined, the gap between the two is very far.

"Boy, be afraid! Even so, you're going to die!"

As soon as the first demon's voice fell, he slashed out directly, and suddenly a terrifying sword shot up into the sky, and the entire galaxy was separated from it, and from a distance, a galaxy opened up again in the galaxy.

"Boom, boom, boom!"

Countless planets rushed one after another, but the sword was unabated, and it slashed directly towards Si Cheng.

As soon as Si Cheng's eyes narrowed, the momentum of the Dragon Slaying Knife alone was terrifying, and this sword was even more terrifying.

"Divine power, immortal power!

Si Cheng shouted, at this moment, he must show his strongest strength, otherwise he will definitely die.

"Thunder destroys the world!"

"Boom ......"

There was a rumbling sound in the air, and a huge thunderbolt emerged, and under the fusion of divine power and immortal power, Tianwei was even more terrifying.

"Huh?" The First Demon frowned slightly, looking at the current Tianwei, his face also sank directly.

"Boom ......"

Tianwei directly met the sword, and with a shocking sound, the sword collapsed, but Tianwei was also shocked, and then dissipated.

Si Cheng's eyes widened suddenly, the power of this knife was so powerful, although it seemed to resist this knife, but this time Tianwei was his strongest means.

"Huh, it's blocked!" The First Demon was also slightly stunned, and his expression was not much different from Si Cheng's.

You must know that the Dragon Slayer Knife is a source weapon, a real source weapon, and its power is even more powerful, and even with his current strength, he can't completely control the slave, because he doesn't really surpass the Immortal Venerable.

Only the kind of powerful person who really surpassed the Immortal Venerable could control the slave, so at this moment, he was shocked, and he didn't expect Si Cheng to be able to resist it at all.

"Hmph! What if you resist it, I want to see how many times you can resist it!"

"Slash!"

The next moment, the first demon shouted, and the incomparably terrifying sword appeared again, and slashed directly towards Si Cheng.
