At the same time, the light blade that Gu Feiyu released was also collapsing, and Gu Feiyu tried his best to use his martial arts to the limit, but he could only scratch the yellow bird's claws, and it could be seen that the damage caused to it was not great.

The fourth-order demon beast turned out to be so terrifying, Gu Feiyu's heart sank suddenly, although he barely blocked the Yellow Bird's attack at the moment, it couldn't cause substantial damage to it at all, and if the Yellow Bird's casual blow touched him, it could be fatal.

Huang Niao didn't expect that someone who didn't look good would be able to hurt it, so he instantly became furious, screamed in the air and used his mouth and claws together, and rushed towards Gu Feiyu again.

The failure of the two attacks had already made it extremely irritable, not to mention that it had been injured on the contrary, which was even more unbearable.

At the very beginning of the fight between Gu Feiyu and Huang Bird, Wang Erlei began to form a magic seal in his hand, and his mouth was even more full of words, and finally at this moment, he finally completed the last step, seeing Huang Bird rushing towards Gu Feiyu fiercely again, and hurriedly waved the Dao Technique in his hand.

A pale blue light, like a firelight, rushed towards the yellow bird quickly through the night, and Wang Erlei shouted: "Brother, I'm here to help you!" ”

Gu Feiyu was instantly dumbfounded when he saw this scene, where was the pale blue light like a fire, it was clearly a fire, okay? He said angrily: "Isn't this a heart fire, your Dao technique is just this thing?" ”

Wang Erlei said eloquently before that he knew Taoism and could help, but it turned out that this so-called Taoism was heart fire! This technique is the most basic Dao technique in the Medicine King Valley, and everyone who can condense the fire of the heart will perform it well.

"Haha...... It's on, roast the yellow bird, ......" Wang Erlei's excited voice suddenly came, Gu Feiyu looked over, and his heart was instantly shocked, Wang Erlei's Taoist technique really set the yellow bird's feathers on fire.

Where could the yellow bird still care about attacking Gu Feiyu and the two of them in mid-air, flapping the burning feathers on his body in a panic, and under the flapping of his huge wings, he quickly extinguished the fire.

Gu Feiyu's eyes lit up at this time, and he said happily: "It really worked!" The yellow bird is actually afraid of fire, and the fat man continues to burn him! ”

This time, Huang Niao was completely angry, and he directly gave up Gu Feiyu and rushed towards Wang Erlei's fat body.

Wang Erlei ran in panic and shouted, "Damn! Brother, hurry up and save your life......"

"Hold on!" Gu Feiyu only had time to say these three words.

Wang Erlei was instantly dumbfounded when he heard this, he didn't know any martial arts, how could he insist on it, the speed on his legs was even faster, and he secretly prayed in his heart that his brother would have to hurry up.

Gu Feiyu's eyes froze, knowing that time was pressing, and he quickly formed a law seal in his hand, and even said word by word in his mouth: "Lin, soldiers, fights, people, all, arrays, columns, in, front, heaven and earth flying clouds, Qiankun borrows the law and heavenly fire, pro!" "Every word of the nine-character mantra must bear a corresponding Dharma seal, although he has always been able to use this Dao technique, but he rarely uses it and is not proficient, so the movement is almost as slow as Wang Erlei.

After this word was spit out, Gu Feiyu's hand was waved out in an instant, and the white heavenly fire was instantly released from his hand, and he pounced towards the huge yellow bird that was attacking Wang Erlei.

The power of the heavenly fire is naturally not comparable to the ordinary heart fire, almost instantly enveloping the body of the yellow bird, the huge yellow bird was instantly burned by the white heavenly fire released by Gu Feiyu, and from a distance, the originally huge yellow bird has turned into a white firebird, and the white flames on its body rise.

The yellow bird burst out with a terrible cry, and the surrounding demon beasts changed color, and their huge wings rolled on the ground for a while, and fluttered for a while trying to fly.

Gu Feiyu rushed forward and dragged out Wang Erlei who fell next to the yellow bird, although Wang Erlei's body was extremely fat, but for a person of Gu Feiyu's realm, this weight was still light.

Wang Erlei had a lot of blood stains on his two arms, and even at this time there was still blood, and even his chest was left with a scar by the yellow bird, but fortunately, the wound was not deep, but fortunately he protected himself well.

Gu Feiyu asked with concern: "Second fat man, how can you still hold on?" ”

Wang Erlei gritted his teeth and nodded, and said, "Fortunately, your Tianhuo came in time, otherwise I would have been eaten by this bird......"

Gu Feiyu let him sit down against a big tree and said, "It's not so easy for him to eat you, we'll roast it tonight!" ”

Seeing that there was no way to stop the burning of the heavenly fire on the ground, the yellow bird flew into the air in a panic, and flew towards the sky with a blazing white flame all over his body.

Where would Gu Feiyu let it get his way, knowing that it would be unwilling, the heavenly fire that had already been prepared waved towards it again.

......The white flames on the yellow bird's body exploded in an instant, and even the hard and sturdy feathers of the fourth-order demon beast could not withstand the power of the heavenly fire in the end, and they instantly turned into ashes under the raging burning of the heavenly fire.

And the yellow bird that lost its feathers, even if it was a fourth-order demon beast, could not keep flying in the air, and it fell to the ground in an instant, but even so, it still did not give up struggling.

The spirit of a demon beast that can reach the fourth order is naturally stronger than that of an ordinary demon beast, seeing that he can't live without destroying Gu Feiyu, he still has a pair of wings that have no feathers with white flames, and a pair of bird claws rush towards Gu Feiyu on the ground.

When Wang Erlei saw this scene, he said: "You won't die even if you burn like this, brother, you have to be careful." ”

Gu Feiyu nodded and said: "How can a fourth-order demon beast be so easy to deal with, the heart fire is not enough to cause damage to it, only the heavenly fire can inflict such a big blow on it, but no matter how powerful it is, it is only a bird, and it can only struggle if it can't fly." ”

Gu Feiyu's hands unleashed the Wind Slash again, raising it high above his head and fusing together, a zhang long light blade instantly slashed towards the yellow bird burning with white flames.

As Gu Feiyu said, a bird that had no feathers and couldn't fly, even if it was a fourth-order demon beast, it couldn't do him any harm, and the Wind Slash instantly slashed down on the yellow bird like a sharp flying sword.

In an instant, blood splattered, accompanied by the terrible scream of the yellow bird, the yellow bird lost the protection of its hard and sturdy feathers, and still could not resist the powerful attack power of the wind slash, and was instantly cut to the ground.

Gu Feiyu took the heavenly fire back, and the yellow bird was already dying at this time, although he was still struggling to stand up on the ground, he still failed to succeed after all, and had lost the ability to move.

Gu Fei let out a long sigh of relief, this battle was by no means easy for him, the power of a fourth-order demon beast was definitely more terrifying than that of a cultivator in the Tengyun realm, and what was even more difficult was the demon beast's ability to resist attacks, if it weren't for the heavenly fire, it would be difficult to cause damage to it at all.
