In the sea of knowledge.

Using the realm sword duel and the realm of the sword turned into the flaming sword dragon, it was like a bamboo, and it slammed towards Hei Xuan.

Hei Xuan looked at the fire dragon that was blasting towards him, and stood there motionless, as if he didn't care at all. Just as the fire dragon was about to engulf him, Hei Xuan slowly raised his right hand.

Boom! An incomparably terrifying energy burst out from his hand in an instant.

The fire dragon stopped less than an inch away from him, a sneering sound in the air. Although the fire dragon stopped, the castration continued. Under the energy of Hei Xuan, there is no trace of progress.

"Very good move, just ...... for me"

Boom! Hei Xuan said, and the energy in his hand burst out again, and it shook the fire dragon straight away.

Yu Gan's body appeared from it and flew out violently.

"It's too weak. ”

Hei Xuan looked at Yu Qian, who flew out upside down, and said disapprovingly, making up for what he hadn't said just now.

The Burning Sun Sword turned into a flash of fire, sticking straight into his side.

Yu Yan's face was extremely pale, and he only felt that his soul was about to be shattered. Looking at the figure in front of him burning with black flames, Yu Yan gritted his teeth, his heart full of shock.

"There are two more tricks. ”

Looking at Yu Yan lying on the ground, Hei Xuan put his hands behind his back and said lightly again.

Yu Yan stretched out his hands to grasp the hilt of the Sun Sword inserted beside him, and then finally stood up reluctantly.

"I know. Yu Yan said.

As he spoke, a look of thought flashed in his eyes, and finally he saw his left hand grasp the void again.

There was a fluctuation in the space, and a long sword with blue light appeared in his hand again.

As soon as this blue shining long sword appeared, the entire space seemed to become solemn.

This blue shining long sword is the Yuan Shi Evil Sword!

"Well, another magical sword!" Hei Xuan looked at the blue light long sword in Yu Qian's hand, and couldn't help but be slightly stunned, and sighed.

Although he was a little surprised, in Hei Xuan's opinion, these two swords were just two pieces of mortal iron held in Yu Xuan's hands. Because Yu Gan's cultivation strength is too weak.

"Then come on!"

Feeling that Yu Qian's aura was also climbing with the appearance of the two swords, Hei Xuan said disapprovingly.

Yu Yan stared straight at Hei Xuan with a pair of eyes, feeling that his aura was vast and terrifying, which was greatly beyond his imagination. Although there is only a difference of one paragraph, maybe the difference between the three and fourth stages is like the third and fourth stages, and the appearance of Xuan Qi has led to a huge difference in the strength of the two stages of cultivation.

"Either way, you have to fight. Yu Yan gritted his teeth.

Adjust the True Yuan Xuan Qi in his body to the peak, and use the power given to him by the Yuan Shi Evil Sword and the Burning Sun Sword to once again move the realm sword duel and the sword realm.

The momentum of the whole person suddenly changed again. Immediately, I saw the two long swords in Yu Yan's hands come out of his hands and turn into two dragons, one green and one red.

And Yu Yan also disappeared in place, the temperature of the entire sea of knowledge suddenly increased, and a flaming giant sword burning that made even the soul tremble suddenly appeared.

Levitating high in the air, it exploded towards Heixuan.

The space suddenly surged, and I saw two stegosaurs, one green and one red, and a flame giant sword bursting towards Hei Xuan.

"Oh? That's kind of interesting. ”

At this time, a slight exclamation finally came out of Hei Xuan's mouth.

In the flash of light, the double dragon and the giant sword had already come to Hei Xuan's face.

I saw him wave his hand casually, and a black energy suddenly burst out from his hand, sweeping towards the double dragon and the giant sword with a terrifying castration.

Boom! There was a sudden vibration in the space, and the double dragon and the giant sword suddenly stopped less than a meter away from Hei Xuan's hand.

"Huh?" said a surprised sound.

Step on!

The sudden power from the Flame Giant Sword made him feel a tremor, and his body couldn't help but take a step backwards.

But Yu Gan's offensive did not decrease at all, and the long sword slammed directly into the black energy screen on his chest, and the entire space centered on the two of them continuously emitted terrifying shock waves in all directions.

The air also made a sizzling sound.

"I really didn't expect that you still have such an attack move, yes, you are worthy of the supreme genius of the human race, the first ascendant to fly up from the lower plane. Hei Xuan's mouth once again let out a hoarse voice, and his tone was full of surprise.

Just as he was talking, he saw Hei Xuan's other hand slowly raised again. The palms of both hands rested on the top of the Twin Dragons and the Greatsword......

Thundered!

An energy that was several times more terrifying than before erupted from his hand again, and the space continued to twist, as if it was being cut and shattered.

Brush!!!

The double dragon and the giant sword were swept by the terrifying energy of Hei Xuan, and finally they couldn't stand it anymore and all collapsed.

Bang! Yu Gan's body suddenly flew upside down and smashed to the ground, his face was extremely pale, and the aura on his body became extremely fragile.

"Yes, this move is enough to sweep in the six-stage Yuan Infant Realm. ”

Hei Xuan took a step and came to Yu Qian's side, looking at the two long swords, one red and one green, beside him, and there was a fluctuation in those dazzling eyes.

Yu Yan gritted his teeth, at this moment he only felt that his body was in pain as if it had been torn, oh no, at this time he was only a spirit body, not a physical body.

The tearing of his soul, he had felt this way more than once.

So immediately, Yu Yan slowly stood up again.

"Thanks for the compliment, I think so too. Yu Yan smiled hard.

"Although you are extremely talented, you are only a sixth-stage Yuan Infant Realm after all. Hei Xuan said again.

"I know, so there's one last resort. Yu Yan looked at Hei Xuan opposite and spoke, his tone extremely calm.

"Why bother, even if you are given ten or hundred moves, you may not threaten me. ”

After listening to Hei Xuan's words, Yu Yan smiled again disappreciatively, "So, do you want to regret it?" or ...... Scared?"

Afraid?

Hei Xuan was slightly stunned, and then a strange laugh came out of his mouth, "Hehe, you are the first to say that I am afraid." ”

"I'd like to see what else you can do, I'm actually looking forward to it!"

In fact, Hei Xuan was also shocked, the strength of Yu Xuan's soul was beyond his imagination, and in the blow just now, he actually used nearly seventy percent of his strength. It would be understandable if a seventh-rank pseudo-immortal realm master let him do this, but Yu Gen was only a sixth-rank primordial infant realm.

"This son has infinite potential, and keeping him must be a big disaster for my demon clan!" Hei Xuan said secretly in his heart.

Yu Yan looked at Hei Xuan opposite, gritted his teeth, and a thought flashed in his eyes. Immediately, as if he had made a decision, he grabbed it with his empty hand, and after taking back the Yuan Shi Evil Sword and the Burning Sun Sword, Yu Yan stood straight in front of Hei Xuan.

"Without a sword?"

Hei Xuan was stunned for a moment, looking at Yu Yan on the opposite side with empty hands, and he didn't understand.
