Xiao Yifeng's fist burst out, and the endless light of stars burst out, directly condensing into a huge shadow of stars in the void.

This star boxing shadow releases the supreme power of heaven and earth, and bombards with the opponent's huge finger.

Boom, boom, boom!!!

A series of roars, endless energy explosion.

Star boxing shadow and xuanming finger collide with each other strongly, and the air waves like a tsunami roll out, and the people around are all retreated by the earthquake.

Kick, kick, kick!!!

Under the attack, Xuanyou trembled, stepped back a few steps, and almost quit the challenge arena.

In a short period of time, Xiao Yifeng broke the attack of the four Nirvana dualistic sons, and appeared extremely strong.

The onlookers all around looked at Xiao Yifeng with a look of shock.

Xiao Yun, Yan Long and Wu Yinghui in the challenge arena are all looking at Xiao Yifeng with a strange look in their eyes.

"Let's go together, just a few of them. It's not enough for me to plug my teeth!"

Xiao Yifeng looks at Xiao Yun, Yan Long and Wu Yinghui.

"Arrogant boy, let me see what you have in the end!"

Wu Yinghui looks at Xiao Yifeng and shouts. A long sword appears in his hand. As soon as the sword appears, it releases a cold breath.

"Today I'll show you the power of my Jiuyou quenched cold sword!"

Wu Yinghui looks at Xiao Yi and drinks coldly. He rushes out and sweeps out with a sword. The cold air of forest breaks out directly.

The level of this sword has reached the level of semi artifact, and the terrible Yin cold force contained in it makes it more powerful.

Bang!

Xiao Yifeng blows out with one fist, and directly collides with the opponent's semi artifact sword. Suddenly, a cold and cold air on the opponent's sword directly rushes into Xiao Yifeng's body.

As soon as the cold and Yin Qi rushed into Xiao Yifeng's body, he ran about in his body. Suddenly, Xiao Yifeng felt that all the viscera and blood in his body began to condense into ice, and the stinging pain swept through his whole body.

Xiao Yifeng immediately frowned.

"Boy, you can see the coldness of Jiuyou!"

Wu Yinghui looked at Xiao Yifeng's expression and sneered.

"A little strength, but not enough!"

Xiao Yi cold drink, the body of a group of flames swept out, the moment that cold air in the red fire under the impact of disappeared.

"How could you be OK so soon?"

Seeing Xiao Yifeng, it was all right in an instant. Wu Yinghui's face changed and a look of shock flashed in his eyes.

Pop!

Xiao Yifeng holds each other's nine you quenched cold sword with his bare hand, and looks at each other coldly in his eyes.

"Asshole!"

Seeing that Xiao Yifeng was ok, Wu Yinghui's face sank. A strong force rushed into the nine you quenched cold sword, and suddenly a roar sounded.

In this sword, a terrible cold air like tornado storm blows towards Xiao Yifeng's palm. In an instant, Xiao Yifeng's palm holding the sword is sealed by the cold air.

Although Wu Yinghui didn't practice the power of ice, he broke out the Yin cold Qi that could freeze people with the help of this semi artifact sword.

"Boy, you are ready to die under my sword!"

Wu Yinghui looked at Xiao Yifeng with a cold look in his eyes, but it was Xiao Yifeng's sneer that welcomed him.

"Ignorance!"

Xiao Yifeng disdains to spit out, holding the sword's hand burst out a group of red fire, this red fire appeared, the invasion of Yin cold air in Xiao Yifeng's arm instantly into nothingness.

At the same time, as soon as the red flame came out, the nine you quenched cold sword was burning, which made the sword tremble violently. At the same time, the flame swept away towards Wu Yinghui.

Seeing the red flame coming, Wu Yinghui's face changed, and he gave up the sword. His body retreated, and his spiritual power burst out.

A defense shield was formed to resist the red flame. However, Wu Yinghui was shocked by the red flame and turned pale.

With a wave of Xiao Yifeng's hand, ChiYan Tianhuo returns to his body. As for the Jiuyou quenched cold sword, it is directly used by him.

"Boy, give me back the nine you quenched cold sword!"

Wu Yinghui watched as Xiao Yifeng put away his semi artifact sword. His face changed and he said directly.

"Now it belongs to me. If you have the ability, take it back from me."

Xiao Yifeng smiles gently.

"You..."

Wu Yinghui's eyes twinkled with anger, staring at Xiao Yifeng and clenching his fists.

"Was it the sky fire that he was using just now?"

The strong men and others of the main gate noticed the flame released by Xiao Yifeng and speculated one after another.

"I didn't expect that this son had mastered a kind of sky fire. It's powerful! It seems that with him, we really hope to win the battle of danta! "Xia Zhenghai looks at Xiao Yifeng with a smile on his face. With the level of his ninth level alchemist, he naturally recognizes that the flame Xiao Yifeng just cast is sky fire.

"Your strength is stronger than before, so let me understand your skills well!"

Yanlong looks at Xiao Yifeng and shouts in a deep voice. It seems that there are two groups of hot flames burning in his eyes, and there is a terrible smell of flame all over his body.

This Yanlong also burst out the triple strength breath of Nirvana, burning with a terrible flame breath, and his strength was stronger than when he was in Jiuyan mountain.

"Come on, let me see how much you've improved!"

Xiao Yifeng smiles gently.

Boom!

Yan Long turns into a fire and rushes to Xiao Yifeng. He attacks Xiao Yifeng fiercely with the power of a terrible fire.

Xiao Yifeng's fist was also full of fire, and the two fists collided with each other.

A series of flame energy and spiritual power ripples burst out, and the void around was twisted and torn apart.

Both of them were retreating, looking at each other.

"Let's have a taste of the real sky fire!"

Yan Long said indifferently, his hands slowly raised, and the burning flames all over his body were more terrible. He rushed to the sky, and above his hands, two red flames were burning.

As soon as the flame came out, the air temperature around the whole challenge arena rose in a straight line, and the horrible flame atmosphere enveloped the whole challenge arena.

All the people in the challenge arena felt that they were in the deep of the fire. Their foreheads were sweating. They urged their own strength to resist the terrible temperature released by the fire.

"Sky fire!"

Looking at the flame released by Yanlong, a look of shock flashed in the eyes of all the people in the challenge arena, other onlookers, and people from all the major departments.

Obviously, I didn't expect that Yanlong had mastered a kind of sky fire, worthy of being an ancient family.
