The Nine Demon Fire is the flame of the Demon Domain, and it should not appear in this world, but at this moment, it just appeared in front of Xu Feng's eyes, and I don't know where Su Guotao got it;

However, the Demon Fire is not an ordinary fire, not everyone can use it, once you are not careful, you will play with fire and burn yourself, even in the Demon Domain, only the Demon King-level powerhouse can use the Nine Demon Fire;

I don't know if Su Guotao is confident or blind, he actually used the formation to summon such a flame, which is even more dangerous than him controlling the six-star formation with five-star strength; You must know that the Nine Demon Fire is known as nothing that does not burn, and every wisp can burn a world, although it is a bit exaggerated, but its power cannot be underestimated;

Looking at the several purple-black flames floating around Su Guotao, Xu Feng couldn't help but show a solemn look on his face;

Su Guotao relied on the power of the array disk to summon dozens of demonic fires, and the moment the demonic fires appeared, Su Guotao suddenly aged a lot, and his originally thirty-year-old face immediately appeared a few wrinkles, and the luster on his skin gradually disappeared, and wrinkles appeared, as if he had aged thirty or forty years old, and became an old man of sixty or seventy years old, his body trembled, and it seemed that he was going to fall to the ground in the next moment;

Originally, the six-star formation counterattacked, Su Guotao was not lightly injured, and at the cost of life, he summoned the Nine Demon Fire, and wanted to kill Xu Feng like a boat, which was also his last killer weapon, and after casting it, he didn't have the slightest power to fight back;

His already cloudy eyes were full of anticipation, and Su Guotao wanted to see Xu Feng burned to ashes by the demonic fire;

"The Nine Demon Fires, nothing is not burning, no matter what resistance you use, silver equipment, gold equipment, it is all in vain, in front of the demon fire, it will be burned to ashes and become the nourishment of the demon fire." Su Guotao said hatefully;

Su Guotao was not worried that the price of summoning the demon fire was too high, as long as he killed Xu Feng, the family would naturally have the fruit of increasing his lifespan for him;

"As long as I kill you, not only will I get a rich reward, but the Su family will also be famous, and my name Su Guotao will also be powerful in the world, haha!" Su Guotao's eyes showed a trace of madness, his weakened legs could no longer support his body, his legs were weak, Su Guotao fell to the ground, but he didn't care when he fell to the ground, he still stared ahead, wanting to see Xu Feng burned to death by the demon fire with his own eyes;

"Swinging the sword thirteen styles, one sword breaks ten thousand laws!" Xu Feng shouted softly, the flying sword came out of his hand, and continued to evolve in the air, and in an instant, dozens of sword lights bloomed from the flying sword, as if a sword had turned into dozens;

Every sword light rushed towards a demonic fire;

"No matter how powerful your swordsmanship is, how can it be as good as the Nine Demon Fire!" Su Guotao roared in a hoarse voice, listening to his ghostly howl, Xu Feng frowned slightly;

One sword breaks ten thousand laws, it is the most powerful one of the thirteen styles of swinging swords, claiming to be able to split ten thousand sword rays at the same time, can split the mountain peaks into flat ground, and the sea into abyssal valleys;

However, Xu Feng had only just comprehended the true meaning of this sword technique, and he could only slash dozens of sword rays at the same time, but these dozens of sword rays were enough to deal with the Nine Demon Fire summoned by Su Guotao;

Bang bang bang~

Each sword shot accurately into a ball of demonic fire, and soon, these demonic flames dissipated, turning into wisps of purple-black mist, dissipating between heaven and earth;

"Impossible, impossible, the Nine Demon Flames are inexhaustible, whether it is physical objects or energy, they can't escape the fate of becoming a demon fire feed, how can such a situation occur!" Su Guotao's eyes oozed blood and tears, he looked incredulous, and he was talking to himself in disbelief;

Xu Feng showed a tired look in his eyes, and he used this trick, which consumed him a lot, seeing Su Guotao's dying and struggling appearance, Xu Feng's eyes narrowed, and with a wave of his right hand, a dragon-shaped sword, accompanied by a dragon groan, rushed towards Su Guotao;

Su Guotao didn't have the slightest strength to fight back at this time, but the fear of death still made him roar and threw out the array plate in his hand;

Rumble~

There was a violent explosion, Su Guotao "poof", and spurted out a mouthful of essence blood, the array disk was his heart and blood, and Xu Feng's natal flying sword, once the array disk was damaged, Su Guotao himself would also be injured in his eyes;

At this time, Su Guotao is like a faint flame, it will be extinguished when he blows a breath, although he used the natal array disk to resist Xu Feng's dragon slash, but the rest of the attack, he will no longer have the ability to resist, the means are all out, Su Guotao at this time, there is no more vigor when he found Xu Feng;

Da Da Da ~ Xu Feng held the flying sword in his hand, walked in front of Su Guotao step by step, listening to Xu Feng's footsteps, as if death was approaching, Su Guotao's eyes suddenly became sloppy, and the frightened look on his face became more and more intense;

"You, you can't kill me, you can't kill me, I'm the Su family's descendant, the Su family's descendant, kill me, the Su family won't let you go." Su Guotao was talking to himself, he felt as if he was roaring loudly, but in Xu Feng's ears, it seemed to be whispering weak and powerless;

A shadow covered Su Guotao, looking at a flash of sword light in front of him, Su Guotao raised his head as if returning to the light, and his two eyes glowed with a strange look;

"I, I am the closed disciple of the formation master Wu Dun, kill me, my master will not let you go, he will definitely avenge me, he is the formation master, you, you can't beat him!" Su Guotao grabbed Xu Feng's trouser leg and shouted hoarsely;

Xu Feng watched the rapid passage of life, Su Guotao, who had gray hair and a wrinkled face, in his panicked eyes, Xu Feng raised his sword and stabbed him in the throat;

"Uh~"

There were still unfinished words in his mouth, Su Guotao's eyes widened, he couldn't believe that Xu Feng really stabbed the sword, you know, this sword stabbed down, but he had a grudge with a formation master;

Wu Dun is the first mage in Shangjing, all the strong people in Shangjing will give him a little face, even if he goes to the capital, there is also a large array of city protection arranged by Wu Dun;

Su Guotao is Wu Dun's closed disciple, all he has learned is taught by Wu Dun himself, Xu Feng actually disregarded Wu Dun's face and directly killed his closed disciple, if this matter spreads to Shangjing, I am afraid it will cause a sensation again;

"I ...... I'm in Hell...... Waiting for you! Su Guotao's eyes showed a fierce look, the corners of his mouth flashed a strange smile, and his head sank;

Xu Feng pulled out his long sword, kicked Su Guotao away, and walked towards the five-turn golden wheel that was still flashing with golden light not far away, you must know that at this time, the countdown to the insect nest is less than an hour, and time must be hurried;
