It was another supreme knife that slashed wildly, and at this moment Si Cheng's face also changed, you must know that this is the source weapon, although he resisted it just now, but it was his strongest means.

"Thunder destroys the world!"

Gritting his teeth, Si Cheng could only use Tianwei again, the sword of the Dragon Slayer Knife was too powerful, only Tianwei could resist, and other means were afraid that they would be directly destroyed.

"Boom!"

With a loud bang, the sword swept across the sky, and it came towards a huge thunderbolt.

Si Cheng's face changed, Tianwei, who did not fuse divine power and immortal power, was not the enemy of the sword at all, and was directly shattered by that powerful momentum.

"Thunder!

Si Cheng shouted violently, and before his words fell, the entire thunder exploded with a bang, and the terrifying impact went straight to the sword.

"Huh, explosion?" Seeing this scene in the distance, a sneer appeared on the corner of his mouth, and then he slashed out again, one in front and one in the back.

"Not good!" Si Cheng's face changed drastically, the explosion of thunder could only deal with one sword at most, and the other was powerless.

"Eighth Style!"

"Heavenly Sword None!"

"The power of the eleven elements, give me a blast!"

At this moment, Si Cheng could no longer be kept, and all the supreme means came out one after another.

"Boom!"

First of all, the energy wave after the thunder explosion directly met a knife ray, and suddenly the two sides collided fiercely, but the energy wave dissipated directly in the blink of an eye, and the sword light actually broke through the energy wave and came again.

"Bang ......"

The next moment is directly bombarded with a punch!

But the sword behind him followed closely behind, and the speed was incredibly fast, and at this moment, Si Cheng's face sank.

"Dragon Slayer! If I didn't have a Dragon Slayer, the First Demon wouldn't be able to help me, but now ......"

Si Cheng felt the crisis, he had been cultivating for so many years, and there were crises everywhere, but they all came over one by one, but how to get past this time.

Because this is the pinnacle battle in the starry sky, that is, Hongjun, Five Elements, Fuxi, these strongest people in the starry sky can't intervene, so who else can save themselves.

Of course, at this moment, Si Cheng didn't expect anyone to save him, everything still had to rely on himself.

The power of the origin is naturally able to deal with the dragon slaying knife, but last time he was careful to give most of the power of the origin to himself, and now it is impossible to ask for it again, otherwise he will fall into a deep sleep.

The Five Elements Order is a semi-source device, which is tens of millions of miles away from the real source device, and it is naturally useless at this moment.

Thinking of this, Si Cheng found that he was almost at the end of his rope, and it seemed that he had come to challenge the First Demon this time, because he had not thought of the Origin Demon Active Device in advance.

"No! I still have the means!"

Si Cheng's big hand slapped directly to the storage bag, and suddenly a large number of divine stones and immortal stones roared out, these divine stones, even the blue and green divine stones that could not be used were taken out, and as for the immortal stones, only red remained.

The pink color was all used up in the last raid, and the red was still left, but it was all taken out at the moment. Suddenly, a large number of divine stones and immortal stones floated around Si Cheng.

"Boom! Absorb the energy for me!"

As soon as his words fell, all the divine stones and immortal stones exploded directly, turning into streams of pure energy, Si Cheng opened his mouth and inhaled them all.

Opening his mouth to suck in energy, especially so many divine stones and immortal stones, it can be said that this is the first time, but so far, there is no way to do it.

"What is Si Cheng doing here?" Hundreds of thousands of miles away, Qingshi's mouth was wide open, his face full of shock.

"Alas, he was fighting against the water, and it seems that he still underestimated the strength of the First Demon, especially the big sword, which was even more terrifying. Fu Xi sighed deeply, a worried look on his face.

Hongjun's face is not very good-looking, Si Chengke is the hope of the earth, to be precise, it is the hope of himself and everyone who walks out of the earth, if he dies here, the consequences will be unimaginable.

The Five Elements, Tongtian, and Primordial did not speak, their faces were extremely dignified, the First Demon was too strong, of course, Si Cheng was also very strong, at least he was not a little stronger than them.

Especially the Five Elements Immortal Venerable, at this moment, he finally saw Si Cheng's strongest means, even the first demon who surpassed the Immortal Venerable could fight until now, if he was himself, he would not be able to take a single move.

"Click"

There was a crisp sound in Si Cheng's body, absorbing a large amount of energy, and at this moment, he directly broke through and entered the Daluo Dacheng realm.

At the beginning, the whirlpool after the Heavenly Tribulation was absorbed for three months, the first two months allowed him to break through from the Great Luo Initial Realm to the middle, and the next month was not enough to break through again, but now it was a breakthrough.

Such a realm can be regarded as the strongest person in the starry sky, of course, there is a peak above, but even if there is such a person, it is not the opponent of Si Cheng now.

And after the breakthrough, the power consumed in the body was replenished, as long as he had the strength, he could continue to fight against the First Demon, he didn't believe that the Dragon Slayer Knife was used as a source weapon, and the First Demon could be used endlessly.

"Boom ......"

At this moment, there were two loud noises in the air, one was the collision of the Heavenly Sword and the sword, one was the power of the eleven elements, and the power of the eleven elements also had the way of heaven.

These two Si Cheng supreme tricks were under the opponent's sword, but they only lasted for less than three breaths, and they collapsed directly, and the sword was not weakened at all, and they came straight to themselves.

"Divine power fusion! Thunder destroys the world!" Si Cheng shouted.

"What? you can still ......" The First Demon was slightly startled, but soon he seemed to have noticed something.

"Have you broken through?" At this moment, the first demon was stunned, so he broke through, and then think about Si Cheng was still in the Immortal Emperor Realm half a year ago, but now he has reached the Immortal Venerable Dacheng Realm, how can there be such a fast speed, even a monster can't do it.

"That's right, I've broken through, Primal Demon, I'll see how long you can use the Dragon Slayer Knife!" Si Cheng said.

Hearing this, Shi Mo's face sank, this is what he said to Si Cheng just now, but now Si Cheng has returned it to himself, yes, the dragon slayer knife is a source weapon, a real source weapon, a powerful source weapon, even if he can't use one of them, because every time he casts it, it will cost a lot of money.

"Hmph, even if you can't do it all the time, it's enough to kill you!"

The First Demon snorted coldly, and then slashed out again, looking at the terrifying sword that roared again, Si Cheng's face was heavy.

He didn't know where the limit of the Primal Demon was, or how many knives he could send, and he could resist one or two swords, but after three swords, he would return to the previous scene again.

"Boom!"

Tianwei and the sword collided violently, and in the entire galaxy, except for the Desolate Ancient Tower, everything else no longer existed, and many cultivators around them fled and died, it can be said that very few people could escape, almost ninety and half of them died under the terrifying energy impact.

One, two, three!

"Boom!"

When the fourth knife was made, Si Cheng couldn't resist it anymore, and flew out directly, spitting blood from his mouth.

"Boy, there is still the last knife, if you don't die, your fate is great!" said in a low voice, because at this moment, he sent out nine knives in a row, which is also his limit, if he still can't kill Si Cheng, he can only give up, because he still has more important things to do, and more important enemies to deal with.

"The last knife, cut me!"

The first demon roared, and suddenly the sword reappeared, heading straight for Si Cheng.

In the face of this knife, Si Cheng felt a sense of powerlessness, at this moment, he really reached the point of despair, and the power in his body was almost wiped out, whether it was a divine stone or an immortal stone.

"Boom!"

But at this moment, a big hand poked out directly from the void, and directly grabbed the slashed knife in Si Cheng's disbelieving gaze, and then pinched it fiercely, and the powerful sword collapsed directly.

"Who?" This sudden scene made the First Demon slightly stunned, raised his eyes to look at the void, and then his face changed.

"Panlong!" the First Demon shouted!
