After calming down, Xiao Tian held the broken star sword's hand unconsciously, and then quickly drove to the top of Kunlun mountain.

Not far out, the black air around a burst of fluctuations, and then a large number of air arrows like raindrops toward Xiao Tian.

Xiao Tian's expression coagulates. The light of the broken star sword in his hand flows like a broken Star River. Countless tiny light spots surround Xiao Tian and quickly meet the air arrows around him!

"Bang! Bang! Bang...! "

When the air arrow collides with the light spot, it actually makes a terrible explosion sound. Layers of air waves spread around, as if to disperse the black gas.

The black air rolled again, and a layer of black gas seemed to be a solid shield to block the air waves.

Xiao Tian held the dark sword with a cold look. Different from the previous attack by demonizing Feilian, he didn't notice any signs of life. It seemed that the sneak attack on him was the same as the black gas.

But Xiao Tian was very clear that there must be something behind the dark air. Otherwise, it would be impossible to achieve this level by relying on the black air alone.

"It's interesting..."

Think of here, the corner of Xiao Tian's mouth slightly set off, also came to interest.

He has been invincible for a long time, and has never met a real opponent. Now, the existence behind the black gas has made him a bit of fighting spirit.

"Destroy this place, see you can't come out!" Xiao Tian suddenly roared, and the broken star sword in his hand bloomed with blue brilliance. A bright shadow of the Star River hung on Xiao Tian's head, and countless stars flowed around. It looked terrible.

"Open it for me!"

Xiao Tian burst out a sound and waved the broken star sword in his hand. A sharp sword light was flying across the sky. In the light of the sword, there was a shadow of stars, which was directly cut on the black air in front of him.

The shadow of the stars broke and annihilated the nearby black gas. Soon, the black gas in front of Xiao Tian was partially annihilated.

A sword mark more than 100 Zhang long appeared in the black air. It looked as if the air tight black air had been bitten off by something.

However, before Xiao Tian could continue to expand the results of the battle, the black air around him quickly rolled, and almost in the blink of an eye, filled the space Xiao Tian had cut out.

Seeing this scene, Xiao Tian can't help but frown and look gloomy.

Although the blow just now was not the result of his all-out effort, even if it was replaced by ordinary celestial beings, he didn't dare to take it hard. However, it didn't seem to have any effect on it, which made Xiao Tian feel helpless.

"What the hell is this?" Xiao Tian holds the broken star sword and scolds in his heart.

"Even if he has not been able to make a breakthrough in the system, even if he has not been able to make a breakthrough in the black spirit system, he still has no right to make a breakthrough in the system."!

This makes Xiao Tian helpless, but also a little frightened. Now he has no authority to understand. How big is the origin of this black gas.

However, he did not know the details of the black air, and repeatedly against the black gas, which made Xiao Tian feel a little uncomfortable.

"The black gas that the host is facing should actually be called magic Qi," the system prompt suddenly sounded in Xiao Tian's mind: "when the host is successfully promoted to Jinxian, and the last function of the system is turned on, you are entitled to know the origin of the evil Qi."
