"This old demon actually made a couplet here...... But what does this 'seventeen or eighteen into the hole, seventy or eighty out of the hole' mean?"

Meng Chen glanced at both sides of the cave entrance, and couldn't help but ask Yan Chixia.

"This old demon calls himself a 'good demon', and in the ten thousand years of cultivation, he has never killed any ordinary person with his own hands. Yan Chixia sneered, and continued: "However, after ordinary people are captured by his clone into this cave, they will be absorbed from the power of the life element, and then let go again. When I went in, I was seventeen or eighteen, and when I went out, I was almost exhausted, and I became seventy or eighty years old......"

"I see...... This old demon of Montenegro is really arrogant. ”

Meng Chen glanced at the couplet again and said slowly.

"Well, if a cultivator is taken captive by him into the cave, then he will definitely die. Therefore, this cave house is also known as the place of death of all souls. ”

Yan Chixia continued.

After a slight pause, Yan Chixia once again said to Meng Chenyuanli: "Brother Meng, after entering the cave, you follow me and listen to my orders. ”

"Good. ”

Meng Chen nodded in agreement.

Yan Chixia didn't say more, her body fell from the sky, let the three series of sword embryos roam around her body to defend, and then strode into the Wanling Cave Mansion.

Meng Chen was also on his heels, and the same imperial envoy dual-line sword embryo flew around his body.

At the same time, he also instructed to the mind of the ghost: "Ghost, explore this cave." ”

"Yes, master!"

Ghost Li quickly agreed, and then controlled the Qinling Golden Goose to explore the induction in the cave.

Yan Chixia, who was walking in front of her, suddenly stagnated slightly, obviously sensing the aura of ghosts.

"Brother Yan, this is the ghost thing I have recovered, which can assist in detecting the danger ahead. ”

Meng Chen nodded secretly in his heart, and at the same time transmitted a voice to Yan Chixia Yuanli.

"Okay, let me know as soon as you find anything. ”

Yan Chixia nodded imperceptibly, and then continued to explore.

"Hmm. ”

Meng Chen agreed, and then asked Ghost Li to excite the power of exploration to the maximum.

However, the power of the ghostly goose's induction only penetrated a few hundred meters into the cave before it encountered obstacles and could not extend forward.

Within the range of these hundreds of meters of the cave, there is nothing abnormal, the height of the cave is about sixty or seventy meters, and the width of the cave is twenty or thirty meters, and there is not much change.

Letting the ghost leave to keep the power of exploration to the maximum, Meng Chen followed Yan Chixia and carefully explored forward.

The power of ghostly exploration does not guarantee 100% that there is no danger ahead, this is the cave of the old demon of Black Mountain, and it must be doubly cautious and careful.

The two of them went one after the other, and after exploring hundreds of meters, Meng Chen quickly transmitted a voice to Yan Chixia Yuanli: "Five hundred meters ahead, spar giant!"

Almost at the same time, the sound of heavy footsteps "clicking" also came from the depths of the cave.

Obviously, this old demon of Montenegro didn't have the intention of sneaking attack at all, so he sent his clone to "greet" Yan Chixia and Meng Chen.

"Three!"

Yan Chixia also quickly transmitted the voice towards Meng Chen's mana.

"Hmm. ”

Meng Chen nodded.

Through the exploration of the ghostly geese, the passage ahead suddenly opened up, reaching a height of two or three hundred meters, and a width of about two hundred meters.

And in this even wider cave, three spar giants about forty or fifty meters tall were striding towards the two of them side by side.

"Whew!"

After Yan Chixia in front of her transmitted the sound to Meng Chen, she immediately activated the sword technique, turned into a streamer, and shot towards the three spar giants.

"Ho ......"

The three spar giants let out a strange laugh together, and six pairs of huge arms spread out together, rushing towards the tiny Yan Chixia.

"Xuanyuan Sword Array!"

Yan Chixia shouted, and the red sword behind her suddenly flew out, flying towards the spar giant in the middle.

The spar giant seemed to know that it was powerful, and when it saw this, its body immediately stopped, and its two huge arms were retracted, protecting the huge head.

However, when the red sword inspired by Yan Chixia was about to collide with it, it suddenly flew upwards and missed it.

At the same time, Yan Chixia's mana transmitted and shouted at Meng Chen, "Brother Meng, use the magic weapon!"

The corners of Meng Chen's mouth twitched slightly when he heard this, but he still quickly took out the eight-barreled Vulcan cannon and the huge bullet box from the spirit interface.

He and Yan Chixia had an agreement before, when dealing with the old demon clone, he would be the main attacker, and Yan Chixia would assist.

How to attack?

Of course, it was the same as when dealing with the combination of the Millennium Dryad and the Thousand Chinese New Year's Eve Fork before, bombarded with the Vulcan Cannon.

"Dada......"

The eight huge barrels of the eight-barreled Vulcan Cannon rotated rapidly, and eight flames of light more than half a foot long spewed out, pouring rows of bullets towards the three hedron giants.

"Knock knock ......"

The dull sound of an explosion echoed through the passage in the mountainside, and the three spar giants were suddenly beaten to the point that their bodies trembled, and they could no longer pounce forward for half a step.

However, this Vulcan cannon bullet mixed with G-type alloy and with a caliber of up to 23.6 mm could not cause substantial damage to these spar giants for a while, but only caused the blue light around them to flow non-stop, and their bodies trembled violently.

Seeing this, Meng Chen immediately lowered the muzzle of his gun and shot at the thick calves of the three spar giants.

In this way, the three old demon clones immediately lost their footing, and the old demon clone in the middle who suffered the most bullet bombardment was even more "whew", like a spar hill, falling towards the ground.

"Hahaha......"

Yan Chixia, who had already flown into the air, laughed, and the snow-colored small sword under her feet flew out and shot at the center of the old demon clone in the middle.

"Oh......"

The old demon clone let out a long scream, and his right arm suddenly raised in front of his forehead.

However, Yan Chixia's blow turned out to be another false move.

"Whoosh!" Yan Chixia herself was a little on the shoulder of the old demon clone, and at the same time, the red sword behind her back flew out again, holding it in her right hand.

With a "buzz", the red sword burst out with a red light shadow two or three feet long, flashing from the neck of the old demon clone.

"Whew!"

The huge head of the old demon clone was immediately cut off by the red light and shadow, and rolled down from the top of the neck.

At the same time, Yan Chixia pointed with her left hand, and a cyan copper furnace flew out from behind it, flying to the top of the mountainside passage.

"Buzz!"

Countless blue lights spread out from the copper furnace, enveloping the other two old demon clones together.

"Dada......"

Meng Chen's eight-barreled Vulcan cannon kept exciting, and he beat the other two old demon clones to the ground, and fell to the ground.

Drawing the gourd in the same way, Yan Chixia's body was like electricity, flashing twice between the two old demon clones, and cutting off the two huge crystal stone skulls again.

Meng Chen's side also immediately stopped activating the Vulcan Cannon.

"Hahaha......"

Yan Chixia laughed heartily, and under the flying of her body, she inspired the red sword to make up a sword for each of the three spar giants that landed on the ground.

After this sword was stabbed, the skull of the spar giant immediately burst out with a little red light, and then quickly spread towards the entire skull.

In less than three seconds, the three crystal stone skulls made three slight sounds, and then burst apart respectively, turning into a large pile of spar powder.

From the beginning to the end, in less than half a minute, the three old demon clones were all killed by the two.

Meng Chen glanced at the old demon clone on the ground, and then couldn't help but look at Yan Chixia.

It has only been a few months since the last parting, and Yan Chixia's strength has indeed greatly improved. I feel that this time to kill the three old demon clones, it is Yan Chixia's main attack, and he is here to assist.

"Hahaha......" Yan Chixia seemed to guess what Meng Chen was thinking, grabbed the beard under her chin, and laughed and said to Meng Chen's mana: "Brother Meng, don't be surprised, this old demon clone is good at attacking, and his defensive power is relatively weak. However, his demonic defense can wander all over his body, if it weren't for your 'magic weapon' that made him have to divide a large amount of demonic power to resist, he would not be able to cut off his head by relying on the ordinary attack of my Xuanyuan Sword alone!

"I see. ”

Meng Chen nodded.

At this moment, a dull and strange voice suddenly came out from the depths of the passage.

"Yan Chixia, it seems that you are already better than blue!

The voice was dull and old, and although it came from the depths of the passage, it echoed throughout the passage of the mountainside, as if the entire stone walls of the cave were making sounds.

Yan Chixia's face changed slightly when she heard this, she looked back at the depths of the cave, and said in a cold voice: "Old demon, the family teacher failed to kill you back then, which is a lifelong regret!

"Haha...... Ancestor is waiting for you here!"

The old voice in the depths of the passage let out another strange laugh, and then fell silent.

Meng Chen, who was behind Yan Chixia, also put the Vulcan cannon and bullet box back into the spirit interface at this moment, and then sensed the demon spirit qi reserve.

Killing the three old demon clones increased his demon aura reserves by about 1,200 points.

In other words, each old demon clone contributed 400 demon aura points to him.

Compared with the original combination of the Millennium Tree Demon and the Thousand Chinese New Year's Eve fork, a single Black Mountain Old Demon doppelganger provided him with a lot less demon aura, but according to Yan Chixia, the Black Mountain Old Demon can summon a hundred doppelgangers at once.

In this mountainside passage, there must be many old demon clones.

On the other hand, using the Vulcan Cannon and Yan Chixia to deal with the old demon clone is indeed much easier than dealing with the Dryad Yaksha Essence in the first place.

The time for him to activate the Vulcan cannon was about twenty seconds, and he consumed more than 2,000 bullets, so that the three old demon clones were beheaded by Yan Chixia together.

Walking towards a headless spar giant, Meng Chen reached out his right hand, wanting to bring it into the spirit interface.

Unfortunately, he urged his mind several times in a row, but he couldn't put away the corpse left by the hedron giant.

"Brother Meng, as long as you are in this Ten Thousand Souls Cave Mansion, you will not be able to put away these old demon clones...... If you can't kill the old demon body today, after ten days and a half months, these old demon clones will be able to recondense themselves. ”

Yan Chixia on the side spoke.
