"Hoo ......"

As the grimace shattered, the black fog that shrouded the entire canyon quickly melted and faded away like ice and snow under the scorching sun.

A black mountain peak that was thousands of feet high and stretched to an unknown width was revealed in front of Meng Chen and Yan Chixia.

On the front of this peak, there is also a grimace with eyes and nose and a pair of huge mouths.

However, the size of the grimace is more than twice as large as before.

"Heaven and earth are infinite, and Qiankun borrows the law!"

Yan Chixia did not hesitate, once again condensed a drop of blood from the center of her eyebrows, and pointed her right hand in the air several times, striking a Tai Chi pattern the size of a face plate, which was integrated into the Xuanyuan Sword.

"Go!"

Yan Chixia's right palm was pushed, and the body of the Xuanyuan Sword suddenly burst out with thousands of red rays of light, shooting towards the huge grimace on the mountain peak.

After this move, Yan Chixia's originally ruddy face was already pale.

Obviously, this kind of attack, which requires the blood of the eyebrows, will have a lot of backlash against him.

"Whew!"

Meng Chen also flew with his sword, stretched his bow and condensed arrows, and shot out three Yuanli arrows, and the finished glyph shot towards the right eye with a grimace like a small lake.

"Bang bang bang!"

The arrow of Yuan Li came first, but when it hit the old demon's huge right eye, it was like shooting into a swamp, and it hardly caused any damage to it.

Immediately after, the Xuanyuan Sword inspired by Yan Chixia flashed with thousands of red rays of light, and it also collided with the old demon's entire grimace.

"Bang Bang! Bang ......"

In the midst of a strange sound, the red and black qi on the old demon's grimace burst out and entangled, almost enveloping the entire grimace.

However, if you can't breathe, the red color will disappear completely, and the old demon's grimace will return to its original state.

"Hahaha...... Yan Chixia, you don't have enough skills, you don't have the strength to beat people, and you still say that you are a demon hunter......?

The old demon opened his mouth and laughed, and his thousand-foot-tall body trembled slightly.

"Whoosh!"

With a move of her right hand, Yan Chixia recalled the huge Xuanyuan Sword again.

After returning to Yan Chixia's hands, the Xuanyuan Sword returned to its original state and changed back to more than four feet long.

"Whew!"

Yan Chixia held the hilt of the sword with her right hand, and grabbed the blade of the sword with her left hand very quickly, making a strong grip.

Crimson blood suddenly gushed out, dyeing the entire Xuanyuan Sword blade into a bloody color.

"Buzz!"

As a large amount of his blood poured into the Xuanyuan Sword, a dazzling red light burst out from the Xuanyuan Sword's sword body again, enveloping his entire body.

"Hmm......"

In the distance, the old demon's huge eyes suddenly widened, and his huge mouth opened up, spewing out a large cloud of black gas, enveloping Yan Chixia.

"Huh!"

Meng Chen's sword flew, and the red gourd in his left hand and the fire dragon mark in his right hand were stimulated together.

"Yo!"

The Iron-beaked Condor flew out and was the first to collide with the black qi.

"Bang!",

With a muffled sound, the black gas rolled and rolled, drowning the iron-beaked condor.

Almost at the same time, the fire qi on the fire dragon mark rolled, and a huge fire dragon quickly condensed, and also crashed into the black gas.

"Bang knock!"

With the addition of the fire dragon mark, the black qi spewed out by the old demon immediately collapsed and flew away.

With two "swishs", Meng Chen took back the iron-beaked condor and the fire dragon mark together.

At the same time, the red light around Yan Chixia's body was also stimulated to the extreme, turning into a red figure the size of dozens of zhang.

"Teng Teng Teng ......"

The red figure walked through the air, closing in on the old demon.

"Descendants of Xuanyuan...... Yan Chixia, you turned out to be a descendant of Xuanyuan......"

The old demon's eyes widened, and he screamed strangely in his mouth, and at the same time, a large cloud of black gas erupted from his eyes, mouth, and nose, and he quickly wrapped towards the red figure that Yan Chixia had turned into.

"Bang!"

The first black qi touched the red figure, but it immediately disintegrated, and it could not cause the slightest damage to the red figure.

Not only that, but after being touched by the black qi, the red figure immediately shook slightly, and dozens of red sword weapons that were exactly the same as the Xuanyuan Sword were transformed from around his body.

"Bang Bang Bang ......"

As the black qi collided more and more, just an instant later, the "Xuanyuan Sword" around the red figure had reached as many as a thousand handles.

"Woo......"

The old monster screamed, and immediately opened his mouth to inhale, retracting all the remaining black qi into his body.

However, this was useless, even if the black qi no longer hit, the "Xuanyuan Sword" around the red figure still kept increasing.

Meng Chen's imperial envoy dual-system sword embryo followed behind the red figure that Yan Chixia had conjured up, and his face was also full of shock at the moment.

Compared to the red figure that Yan Chixia turned into, he was like a little ant at the moment.

However, Meng Chen could also clearly feel that Yan Chixia, who was wrapped in a red figure, had a high and low aura on her body, which was strong and weak, as if she was in danger of "falling into the realm".

It seems that although Yan Chixia now has the strength to perform such a powerful spell, the price she has to pay is also very great.

"Shadow of Xuanyuan, Ten Thousand Swords Dynasty Sect!"

Without waiting for Meng Chen to think about it, Yan Chixia in the red figure suddenly shouted.

"Zheng Zheng Zheng ......"

The "Xuanyuan Sword", which had evolved to more than 10,000 handles, roared together, and at the same time, the sword blade forward, and ten thousand swords fired together, shooting towards the old demon body.

"Yan Chixia, the ancestor fought with you!"

The old demon also shouted angrily, and the body that was as high as a thousand feet suddenly shook violently.

"Buzz!"

With the violent shaking of the old demon's body, invisible forces descended from the sky, enveloping more than 10,000 "Xuanyuan Sword", the red figure that Yan Chixia turned into, and Meng Chen, who followed behind.

As if suddenly sinking into a huge quagmire, Meng Chen immediately felt the pressure around his body increase suddenly, and even the dual-system sword embryo under his feet trembled slightly, wanting to fall downward.

"Whew!"

The power of the Yang around Meng Chen's body flourished rapidly, completely dissipating this invisible pressure.

However, the red figure that Yan Chixia turned into in front of him, as well as the more than 10,000 Xuanyuan swords that appeared, were frozen in the air under this overwhelming invisible pressure, and they could no longer take a step forward.

"The distance is still not enough!"

Meng Chen's brows furrowed, and the power of the Yang was activated again, urging the dual-system sword embryo under his feet, just wanting to miss Yan Chixia and rush forward.

However, at this time, it was a sudden change.

"Xuanyuan's Fury!

Yan Chixia in the red figure let out a loud shout again.

"Buzz!"

An even more majestic force rose from the red figure.

"Zheng Zheng Zheng ......"

More than 10,000 Xuanyuan swords rang again, and then suddenly broke free of their restraints and shot towards the old demon body.

"Ah......h

The old demon body shouted in shock, and on a huge ghost face, it was full of extreme fear.

"Sneer......"

Before he could react again, more than 10,000 Xuanyuan swords had all been pierced into the old demon's body.

"Buzz!"

The invisible force that enveloped all around suddenly retreated like a tide.

At the same time, the thousand-foot-tall old demon body suddenly froze for a moment, and then exploded!

"Boom!"

Countless black gravel burst out, and the old demon was as high as a thousand zhang above the body, and a huge gap of four or five hundred zhang exploded at once.

"Bang!"

The red figure around Yan Chixia also collapsed at the same time, and Yan Chixia's body, which was covered in blood, shook twice, and then fell down.

"Huh!"

Meng Chen's sword flew and caught Yan Chixia.

"Brother Meng, escape! The old demon is not dead, we can only do this step......"

At this moment, Yan Chixia's face was pale, and the realm aura on her body completely fell, compared to when she first met Meng Chen, it was much worse.

As Yan Chixia spoke, the black gravel that was originally falling and flying in all directions suddenly froze.

"Really not dead yet?"

Meng Chen was taken aback.

Holding Yan Chixia in his right hand, he shook his left hand and held a giant cannon with a glittering blue light in his hand.

Heavenly Cannon!

"Boom......"

Meng Chen's sword flew quickly, and while activating the Heavenly Xuan Cannon, he quickly approached the old demon body.

The effective range of the Tianxuan Cannon is only five hundred meters, and if it does not get closer to the old demon body, it will not work.

At the same time as Meng Chen flew forward, the black gravel in the sky that had been frozen in mid-air had already shook in unison, and then flew backwards towards the old demon body again.

"Boom......"

Meng Chen's body flickered, avoiding all the black stones that crashed into him.

About three seconds later, a huge incandescent white light shot out from the muzzle of the cannon, instantly hitting the gap that exploded in the old demon's body.

"Boom, knock!"

In an earth-shattering explosion, the old demon's body shook violently, and from the gap, it suddenly collapsed downward.

As for the black stones that were about to fly back, they floated in the air again, and then fell down like raindrops.

"This ......"

Yan Chixia, who had a languid look on her face in Meng Chen's hand, and no longer had any hope, suddenly widened her eyes.

"Brother Meng, enter that gap!"

Ignoring anything else, Yan Chixia lifted her spirits and quickly transmitted her mana to Meng Chen.

"Good!"

Meng Chen didn't hesitate at all, holding the Tianxuan Cannon in his left hand and Yan Chixia in his right hand, he flew towards the gap that the old demon's body had exploded.

Yan Chixia turned over her hand and took out a pill and swallowed it, and then broke free from Meng Chen's hand.

"Brother Meng, if you want to completely destroy the old demon, you have to destroy his demon core, and Xuanyuan Sword can find the location of his demon core!"

Yan Chixia reluctantly commanded the three-series sword embryo, and while recalling the Xuanyuan sword, she wanted to quickly transmit mana to Meng Chen.

"Well, does Brother Yan support it?"

Meng Chen nodded as he asked Yan Chixia Yuanli Transmission.

"No problem!"

With a wave of her right hand, Yan Chixia released the Xuanyuan Sword and flew in front to lead the way.

However, looking at his situation, it is obvious that he is already at the end of the crossbow, and he is just trying to support it. As for the Xuanyuan Sword, which was originally surrounded by red light, it was already dim to the extreme at this moment, and only a little glimmer of light flickered on the sword body.

While speaking, the two of them had already entered the gap that the old demon's body exploded.

"Huhuhu......"

A large amount of thick black qi quickly wrapped towards the two of them.

"Whew!"

Meng Chen flicked his right hand and activated the Fire Dragon Mark again.

As soon as the fire dragon came out, those rich black qi immediately dissipated a lot, but the black qi behind it was heavy, and I didn't know how far it extended.

"Brother Meng Chen, go over there!"

Yan Chixia pointed her hand and followed Xuanyuan Sword to the right.

Meng Chen nodded slightly, and the sword caught up with Yan Chixia, and at the same time turned his hand to put away the fire dragon mark, and then took out a talisman and slapped it on Yan Chixia's shoulder.

"Buzz!"

A punch of cyan light shrouded Yan Chixia inside.

True Yuan amulet.

There are only four of these talismans left, but Yan Chixia obviously consumes a lot of money, and she is already a little powerless to travel through this rich black qi in the old demon's body.

With the blessing of the True Yuan amulet, Yan Chixia immediately perked up, accelerated the Imperial Envoy's three-series sword embryo, and followed the Xuanyuan Sword to fly forward.

However, the black qi in the old demon's body was also very powerful, and although it couldn't completely stop the Xuanyuan Sword, it also slowed down its speed a lot.

"Brother Yan, let me clear a road!"

Meng Chen quickly transmitted the sound towards Yan Chixia's Yuan Force, and at the same time threw a hundred Yuan Energy Stones into the Heavenly Xuan Cannon Crystal Groove, and the Imperial Sword flew forward to stimulate it again.

At this moment, the old demon was obviously beaten by the previous series of attacks, and if he didn't take this opportunity to do it with all his might, I am afraid that it would be even more difficult to kill the old demon in the future.

About three seconds later, the Tianxuan Cannon once again shot out a huge incandescent white light, sweeping away all the black qi and black stones in the five hundred meters in front of him.

Yan Chixia's spirits were greatly lifted, and she once again controlled the Xuanyuan Sword to speed up and flew forward.

Flying out of the path cleared by the Heavenly Xuan Cannon, Meng Chen, under the guidance of Yan Chixia, activated the Heavenly Xuan Cannon for the third time.

After firing the Heavenly Xuan Cannon four times in a row, a black-colored boulder with a diameter of ten zhang appeared not far in front of the two of them.

"The Spirit of the Earth!"

"The demon core of the old demon!"

Meng Chen and Yan Chixia were surprised together.

"Brother Meng, you can't use your magic weapon, let me come!"

Yan Chixia laughed, quickly flew forward and held the Xuanyuan Sword in her hand, stabbing towards the old demon core, that is, the huge earth essence.

"Bang!"

Xuanyuan's sword stabbed the demon core, but it only burst out a cloud of black light, and it couldn't break the demon core.

Obviously, this demon core also has its own defensive power.

"Don't use magic weapons, use weapons to break through his defenses. ”

Yan Chixia continued to swing her sword and slash while quickly saying towards Meng Chen.

"Good. ”

Meng Chen also took out the Norka Giant Sword with his backhand and attacked the old demon core with Yan Chixia.

The power of the Tianxuan Cannon is too powerful, and it may destroy the demon core as soon as it is blasted out. destroyed the demon core, and the important purpose of his and Yan Chixia's trip was tantamount to failure.

Fortunately, when he arrived here, the old demon body did not have any power to resist, although a large number of black qi and black stones were mobilized to attack the two of them, but Meng Chen activated the power of the Yang to attack at will, and blocked all these attacks.

"Ding-ding-ding-click......"

After a series of slashing and stabbing for dozens of breaths, the black light circulating above the old demon core finally disappeared.

"Bang knock!"

As the black light disappeared, the huge old demon core was immediately cut open by Yan Chixia's Xuanyuan sword, and shattered into seven or eight large and small black crystals.

"Whew!"

A large cloud of black gas suddenly flew out of the black crystal, heading towards the outside.

"Definitely!"

Yan Chixia, who had been prepared, waved her left hand and immediately released the cyan copper furnace, enveloping it in a large cloud of black qi.

The black gas immediately flew as slow as a snail, slowly clashing back and forth in the brilliant light released by the cyan copper furnace, but it could not get out of the enveloping range of the copper furnace at all.

"Yan Chixia, I have no grievances with you, and he came to the door by himself for the festival with your master...... The old man has been cultivating for thousands of years, but it is not easy, why do you want to kill me completely?"

The black qi spoke extremely slowly, and hissed towards Yan Chixia.

"Hehe, everyone is punished by demons and monsters, since I, Yan Chixia, am a demon hunter, I am born to be your mortal enemy!"

Yan Chixia smiled, and at the same time urged the Xuanyuan Sword to enter the enveloping range of the cyan copper furnace and attack towards the black qi.

When the black qi met the Xuanyuan Sword, it was like encountering a nemesis, and it let out a miserable howl, and the dimming shrank rapidly.

That is, in a few breaths, the black gas has turned into gray gas, shrinking into a fist-sized mass, and the original roar and scream have also turned into an almost inaudible "hum" sound.

Meng Chen held the Noka Giant Sword in his hand and stood aside to watch, without moving.

Yan Chixia is a real demon hunter, and he is obviously better at killing monsters like the old demon of Black Mountain, and he doesn't need to make any more moves at this moment.

However, at this moment, the ghost that had been lurking in the fiber on his shoulder suddenly transmitted to Meng Chen's thoughts: "Master, can I try to take away the old demon of Black Mountain?"

"What?"

Meng Chen was taken aback.

"Master, the old demon of Montenegro has run out of oil, I think I should be able to take him away!"

The ghost repeats again quickly.
