Li Changsheng boasted that his strength was no less than Duan Aotian, but after all, he had never fought against a real master, and he couldn't help but be shocked when he saw his momentum of looking at the world. Cold sweat broke out on Li Changsheng's forehead, and Duan Aotian was by no means easy, in front of Li Changsheng's calm and sharp momentum, he was also terrified, and his hands holding the handle of the knife couldn't help but tighten and tighten.

"Hah!" Duan Aotian shouted violently, raising his knife in both hands and slashing at Li Changsheng.

Duan Aotian's shout, his voice was full of internal force, even with his superb internal cultivation, he couldn't help but be shocked slightly.

Before the knife move arrived, the sword wind arrived first, and the white clothes on Li Changsheng's body were blown violently by the strong wind brought up by the knife move.

Li Changsheng saw the fierce momentum of this knife, and his heart froze, and he hurriedly waved his knife to resist.

"Dang!"

There was a loud bang.

Two knives intersect.

Although Li Changsheng's skill was above Duan Aotian, Duan Aotian took advantage of the sword and the first move, Li Changsheng's wrists were shocked and numb, and Duan Aotian was even more uncomfortable, Li Changsheng's rebound force made him almost unable to stand.

This move, although the two of them tested each other, they also showed more than ninety percent of their skills. The sword wind was raging, and the ground covered with low grass under the soles of the two feet was split.

The two tried to find out each other's details a little, then they didn't spare their hands and began to attack.

"Dangdangdangdang......" The sound of the two knives intersecting frequently sounded.

"Boom ......" The knife qi was vertical and horizontal, and the grass was cut into pieces.

Between breaths, the two exchanged dozens of moves, sparks splashed everywhere, and both knives suffered a huge impact.

Under the moonlight, the faces of the two began to redden, which showed that neither of them was relaxed.

After a fierce exchange, the two retreated slightly, their chests rising and falling slightly.

"Good knife technique!" Duan Aotian praised.

"You're not bad either!" Li Changsheng said.

The two paused slightly, then exchanged hands again, tangled.

Duan Aotian's sword technique was simple and direct, but it was very powerful, the momentum was like a rainbow, and it was as firm as a mountain, and any opponent with his skill seemed to be destroyed by his sword technique. His nickname of 'the world's first knife' was not a fluke, but a bloody battle piled up.

Li Changsheng's sword technique is a mixture of the Guiyuan sword technique and the understanding of the sword technique in the Heavenly Demon Dajiuzhao. The Guiyuan sword technique itself is a swordsmanship based on chopping and slashing, which is suitable for all kinds of wide swords, similar to narrow knives, and the sword technique of the Heavenly Demon Dajiu Zhaozhong is taken from the scimitar knife method of the alien race outside the Guan. This kind of knife technique is not only crushed by the brilliant momentum, but also mixed with the treacherous ferocity of the demon path.

Duan Aotian was very shocked and strange about Li Changsheng's sword technique, how did Li Changsheng practice this sword technique that combines good and evil? It's a pity that Li Changsheng won't tell him.

The two exchanged hundreds of moves, and they gradually became angry. Duan Aotian's sword was no longer condensed on the blade, but came out of the knife, and the target a few feet away could also be cut off in one fell swoop. His sword is a white light, looking from a distance, it seems like a god is mighty, so not spectacular.

Li Changsheng's sword yuan is colorless and qualityless, and it seems to be tepid, but its danger is far above Duan Aotian's sword. Duan Aotian's sword gang can be dodged with his eyes, but Li Changsheng's sword yuan is difficult to find with his eyesight, and can only be judged by his rich experience and wonderful feelings. Li Changsheng's colorless crescent-like sword element caused huge trouble to Duan Aotian, making this 'No. 1 sword in the world' feel a little dwarfed.

From the eyes of outsiders, Li Changsheng was already surrounded by Duan Aotian's heavy white light sword gang, and he was in danger. However, Duan Aotian, who was in the middle of the battle, felt the opposite, his sword gang was broken to pieces by Li Changsheng's sword element, and in the face of Li Changsheng's atmospheric and strange sword technique, he was already a little powerless.

As a person who can live for the sword and die for the sword, Duan Aotian will never allow himself to be defeated before he reaches the peak of the sword path, so he took the risk.

Yiyi Imperial Sword, as the supreme realm in the sword technique, Duan Aotian has not yet understood it, but he has no choice, if he wants to defeat Li Changsheng, he can only use Yiyi Imperial Knife and sacrifice his life.

As soon as Duan Aotian used the Yiyi Imperial Sword, the power of the sword technique immediately multiplied, and the white sword became even more powerful and swift, which caught Li Changsheng a little off guard. Li Changsheng had always had the upper hand, but he was also pulled over by Duan Aotian. The situation flipped, Duan Aotian became the main attack again, and Li Changsheng could only defend passively.

"Boom......"

The corners of Li Changsheng's clothes were cut off, and they all turned into pieces and fell into the air.

Fortunately, Li Changsheng's light skills were peerless, and he dodged Duan Aotian's counterattack with 'Tianluo footwork'.

Li Changsheng was in a cold sweat, and thought with some fear: This is the Yiyi Imperial Sword? This Aotian is going crazy, with his realm, can he use the Yiyi Imperial Sword? He doesn't want to live, I can't die with him.

The two continued to struggle, and had already moved far away from the place where the fight had begun, to the vicinity of a dense forest.

In Li Changsheng's opinion, Duan Aotian in this state is very dangerous, and he may also be planted in his hands, but whether he can maintain this state for a long time, Li Changsheng took a negative view.

Then, now it's time to drag on and find a way to get through Duan Aotian's violent state. Seeing the dense forest on the side, Li Changsheng's heart moved.

When Duan Aotian's fierce moves were a little old, Li Changsheng immediately used the 'Tianluo Footwork' to dodge Duan Aotian's sword gang and rushed towards the dense forest.

Duan Aotian was in a hurry, and was carelessly taken out of his attack range by Li Changsheng for a while, how difficult it was to maintain the upper hand.

Of course, Duan Aotian was unwilling to let Li Changsheng out of the scope of his sword.

And Li Changsheng was also very helpless, his moves and skills were undoubtedly above Duan Aotian, but Duan Aotian was like taking a stimulant, his attack power rose suddenly, and he had already surpassed himself, making himself embarrassed, and he had to avoid his edge for the time being.

Duan Aotian saw Li Changsheng approaching the dense forest, and sneered in his heart, there is a dense forest blocking the road in front of you, and then you are tracking with a knife, now it depends on where you are running.

Li Changsheng and Duan Aotian thought completely differently, as long as I ran into the dense forest, no matter how powerful your sword was, it would be weakened by the dense forest, and it would not be a threat to me. The power of my sword itself is above your sword, and when your stimulant time passes, see how I clean you up.

As soon as the two chased and fled, they came to the edge of the dense forest in an instant, Li Changsheng was already close to the dense forest, and Duan Aotian was also ready to gather the sword gang for a long time.

Li Changsheng was about to enter the dense forest, and Duan Aotian made a move.

"Ha! Sword fight the world!

Duan Aotian swung the big sword, emitting one hundred and eighty-eight white rays of light, and shot densely towards Li Changsheng's back.

The dense sword light of this move instantly went towards Li Changsheng's cover, like a small meteor shower, which looked spectacular and beautiful, making it difficult for people to imagine that such a gorgeous move actually had the power to destroy the world.
