Sun Xiaofei's divine sense locked on the figure of the wind demon, and as soon as the latter moved, he immediately cast the Great Five Elements Escape Technique, and escaped into the ground with a bang, avoiding the attack of the wind demon.

The Wind Demon suddenly lost Sun Xiaofei's figure, and his soul power immediately spread out, sensing a trace of aura moving rapidly underground. The Wind Demon laughed fiercely, and the wind elemental quickly gathered towards him, solidifying into a layer of cyan crystals on the sword body, and the crystals were mixed with black stripes, exuding a cold aura.

The wind elemental rioted for several miles around the Broken Soul Cliff, and the wind was raging everywhere, flying sand and rocks, and many demonic beasts sensed the danger and fled the place one after another.

However, in the blink of an eye, the wind demon gathered a large number of wind elements, and the sword in his hand turned into a huge crystal sword, with blue light flashing, crystal smooth, and it looked gorgeous and moving.

The crystal sword condensed by the wind demon is not simply beautiful. I saw him slash down the ground suddenly, this sword technique he had practiced for many years, and he was able to exert the great power of the wind attack. He was ready to use this blow to bombard Sun Xiaofei.

"Boom!"

A bright light flashed in the air, the crystal giant sword slashed to the ground, the ground was unbearable to this huge force, and suddenly cracked a deep trench, the crystal giant sword gradually shrank in size, and the differentiated wind system power rushed into the ground, and countless irregular cracks appeared on the edge of the trench, like a spider web, quickly spreading into the distance.

Wind Demon's skill attack, as if it was about to cut the Broken Soul Cliff into two pieces, was terrifying, and the ground of the Broken Soul Cliff became unrecognizable, full of cracks of different lengths.

"Huh!"

Sun Xiaofei was underground, and through his divine sense, he could sense the wind demon's every move and the changes on the ground. The moment the crystal greatsword fell, he fled the place in time.

The Great Five Elements Escape Technique is worthy of being an ancient supernatural power, and the speed of movement in the ground after casting it is much faster than that of him on the ground. Sun Xiaofei's figure flickered, and he spanned a distance of dozens of zhang, and appeared strangely behind the wind demon.

"Five Elements Sealing Technique!"

As soon as Sun Xiaofei appeared, he raised his hand and cast the sealing technique of sealing the magic technique, after he was reborn, he was lucky to have the innate body of the five elements, so that he could cultivate the Great Five Elements Escape Technique and this set of sealing magic techniques, otherwise, he could only practice the sword cultivation technique, and the sealing technique naturally could not be cultivated.

From Sun Xiaofei's body, gold, wood, water, fire, earth... These five dazzling golden runes formed a ring, and as soon as they appeared, they burst one after another, forming a multicolored light curtain to cover the wind demon.

The Wind Demon was furious, and under the light curtain, he lost the existence of the Wind Element. The moment Sun Xiaofei appeared, he had already noticed it, but he didn't expect that the latter's cultivation method was so magical, he couldn't dodge, so he was trapped in it inexplicably.

Sun Xiaofei seized the opportunity with one move, and he didn't dare to leave anything to chance, he knew that he had not fully mastered the nine-character true recipe of the Demon Sealing Technique, and he could not exert the full power of the sealing technique, so he could only temporarily trap the Wind Demon and could not seal the other party for a long time.

"The five seals are blended, combined!"

The true yuan power in Sun Xiaofei's body was running wildly, and several major magic seals of the nine-character true recipe were played out one after another, and the sun wheel seal, the large and small lion seals, and the internal and external binding seals fell on the seal's colorful light curtain and merged together, strengthening the power of the seal.

The runes on the multicolored light curtain flickered and flowed, and the shape gradually shrank, and a huge force pressed the wind demon.

The Wind Demon was furious, and frantically bombarded the sealed light curtain, the light curtain rippled layer after layer of folds, and withstood the huge impact of the attack, and the power of the impact on the light curtain formed ripples and spread everywhere, and was decomposed by the runes on the light curtain and transformed into the energy of the seal.

However, there were also some runes, which burst and dissipated under the continuous critical attacks of the wind demons, and the light curtain was a little dimmed. Seeing this situation, the Wind Demon knew that this seal also had a certain limit to bear, and beyond this limit, the seal would naturally be broken. He gathered his strength to bombard one place more violently.

Gu Kun, who saw this scene from a distance, rolled his eyes sharply, thinking that his Black Nightmare Knife was still in Sun Xiaofei's hand, so he immediately gritted his teeth and moved his body and rushed towards Sun Xiaofei. Even if he knew that he would be punished by the Wind Demon afterwards, he couldn't care much about it, and it seemed that if he didn't make a move, the Wind Demon would be in danger.

While Sun Xiaofei was reinforcing the seal, he had already noticed Gu Kun's actions, and as soon as his heart moved, he summoned Xiaohui to help.

"Roaring ..."

Gu Kun rushed to Sun Xiaofei's place a few feet away, and was intercepted by a black shadow that suddenly appeared.

Xiaohui received Sun Xiaofei's summons and immediately rushed over, and as soon as he came out of the ground, he saw Gu Kun. Xiao Hui raised his head and roared angrily, and the big stick smashed down on Gu Kun's head with a gust of evil wind.

Seeing that Gu Kun had been stopped by Xiaohui, Sun Xiaofei restrained his mind and dealt with the wind demon wholeheartedly. The strength of the other party was far beyond his imagination, and the shock from the seal, and he who was connected to the seal's heart also suffered a strong impact.

All the meridians in his body, because of the crazy walking of the True Yuan Force, have already cracked. At this time, he couldn't turn back, and he was already riding a tiger.

Once the Wind Demon breaks the seal, the consequences are unimaginable. Only by going all out can he get a glimmer of life.

Sun Xiaofei pinched the trick, and the phantom of the treasure bottle seal appeared, his body was in the bottle, and a huge suction force was generated at the mouth of the bottle, and the aura of the surrounding heaven and earth surged sharply, entering it from the mouth of the bottle.

In the blink of an eye, Sun Xiaofei's body was submerged in the thick aura, he opened his mouth and inhaled, and those auras entered his body like a long dragon, walked along the meridians, was absorbed by Jin Dan, and then transformed into pure true yuan power.

This is a tough battle, Sun Xiaofei is constantly strengthening the seal, and the wind demon is constantly breaking the seal. The two are locked in a tug-of-war, and whoever can hold on will win the final victory.

Under the pressure of the lack of external energy supply and the increasing strength of the seal, the attack of the wind demon gradually weakened. Sun Xiaofei still didn't dare to be careless, who knows if the wind demon was disguised.

As Sun Xiaofei stepped up, the runes on the colorful light curtain became brighter and brighter, and the golden light appeared dazzling.

The wind demon suddenly stopped attacking, the random attack is used for ditches, the seal can absorb the energy of the attack to strengthen, but there is also a limit to bear, once the power of the attack exceeds the limit of the seal, the seal will naturally break. He knew that if he couldn't break the seal with a single blow, the seal would remain. Now he has to gather his strength, perform the strongest attack, and break the seal in one fell swoop.

The wind demon's abnormal behavior immediately aroused Sun Xiaofei's vigilance, he pondered for a while, his hands changed rapidly, and Jin Dan was overloaded.

Both of them are casting their own secret techniques, ready to deal a fatal blow to the other. An astonishing spiritual power gradually spread out from Sun Xiaofei's body, his body was shrouded in a layer of golden light, and countless runes floated out from between his hands, surrounding him.

The Wind Demon suddenly let out a roar, and a terrifying wind force erupted, stretching the sealed multicolored light curtain open, and the long sword stabbed towards the light curtain. If Sun Xiaofei was inside, he could see that at the end of the long sword, a cyan light appeared, and in this light it was extremely sharp, and the space in front of him cracked silently.

Sun Xiaofei's eyes suddenly flashed with runes, and then a phanther appeared behind him, his appearance was blurred, he was wearing armor, and his hands were folded and he issued a mysterious and obscure spell.

"Boom!"

The seal broke, countless runes burst, and a swift figure flew out of it, shooting towards Sun Xiaofei.

Sun Xiaofei snorted, the phantom collapsed, and a trace of blood appeared on his mouth and nose. A trace of firmness flashed in his eyes, Sun Xiaofei controlled the Sky Sword to shoot out, strange runes loomed on the sword, and as soon as he slapped his body, a dark blue armor appeared.

"Boom...... Boom!"

The Sky Sword and the Wind Demon collided together, and a loud bang broke out, and layers of shock waves spread out like ocean waves, and everything around them was touched by the shock wave and directly turned into powder.

Sun Xiaofei threw out a large number of defensive spirit runes, turning into layers of light curtains that enveloped his whole body, and his body moved, and flew into it against the shock wave.

Sun Xiaofei detonated the power of the seal inside the Sky Sword, and the inner and outer seals turned into transparent silk threads and shot out. The Wind Demon's body was shot by the strange silk thread, as if it had been immobilized, and it suddenly stopped.

At this time, Sun Xiaofei appeared in front of him, tapped his forehead with one hand, and shouted: "Break!"

The wind demon, who was fixed by the power of the inner and outer seals, had no power to resist, and the light in his eyes gradually dimmed. His soul was blasted away by Sun Xiaofei's invasion of the sea of consciousness.

The Wind Demon's soulless body fell limply and fell to the ground below with a thud.

Gu Kun, who saw this scene from a distance, was shocked and turned away, and he couldn't worry about entangling with Xiaohui anymore and turned around and fled.

Sun Xiaofei was powerless to pursue, and hurriedly ordered Xiaohui to catch up. Xiao Hui's Little Five Elements Earth Escape Technique was unleashed, and the earthy yellow light on the ground flashed, and it lost its figure in an instant.

Sun Xiaofei weakly took some spirit stones from the mountain to recover the lost spiritual power, and his mind and true yuan power were greatly consumed in this battle. There were bursts of sharp pain in his body, and Jin Dan had already cracked.

Glancing at the Broken Soul Cliff that was almost collapsing, Sun Xiaofei grabbed the body of the Wind Demon and flew down the cliff. He urgently needed a quiet place to retreat and recuperate.

At the bottom of the cliff on the other side of the Broken Soul Cliff, it was pitch black, and the wind was blowing violently, which was difficult for Sun Xiaofei, who was protected by a protective light shield, and he fell smoothly to the bottom of the cliff.

The cliff wall was uneven, crawling with some vines and plants, Sun Xiaofei saw that there was a cave suitable for him to recuperate, so he flew into it, repaired the cave slightly, sealed the entrance of the cave with a boulder, and began to retreat and recuperate.

As for Gu Kun, he is still very confident in Xiaohui's strength. One-on-one, Gu Kun is by no means Xiaohui's opponent. Everything is still going to wait for him to resume his cultivation and then make plans.

The Broken Soul Cliff still stands, and only the traces left on the ground are all over the ground, witnessing the thrilling battle just now. No one knew that a generation of notorious wind demons had fallen here.

Half an hour later, Xiaohui appeared on the top of the cliff, there were some blood stains on its body, some of which were its own, some of which belonged to Gu Kun, but unfortunately he did not kill Gu Kun and was escaped by him.

Xiaohui was hovering on the top of the cliff, and it could feel that Sun Xiaofei was below. Xiaohui didn't dare to disturb Sun Xiaofei, turned around and left the top of the cliff, found a cave nearby, and guarded Sun Xiaofei's surroundings.
