After that, the two laughed together again.

"Meng Chen, I, Yan Chixia, have never been my brother, but in the future, you will be my brother!"

After laughing for a long time, Yan Chixia said to Meng Chen with a flash in her eyes.

"It is Meng Chen's blessing to have a brother like Brother Yan!"

Meng Chen was also slightly excited in his heart.

For Yan Chixia's character, Meng Chen also admired it very much.

Yan Chixia can be called the world's first chivalrous man in Liaozhai, whether he was reading Liaozhai stories or watching Liaozhai film and television dramas, he admired this person very much in his heart.

I didn't expect that one day, I would be able to really become brothers with Yan Chixia.

"Hahaha......" Yan Chixia laughed heartily again, then let go of the palm holding Meng Chen, turned to the ghost and glanced over there, and said: "Meng Chen, after your ghost servant took away the old demon of the Black Mountain, the old demon core and those doppelganger remnants are very important, we will each only take a small piece of the demon core, just use it." ”

With that, Yan Chixia turned around and came to the crumbling old demon core, and picked up a demon core that was only the size of a bowl.

"Good. ”

Meng Chen didn't say much, and he also picked up a demon core of about the same size.

There is also a big difference in the quality of the essence of the five elements, just like the "Fire Beast King Neidan" that I got at the beginning, although it is only the size of a fist, the fire essence contained in it is not worse than the large piece of thousand-year-old demon wood core that I got at the beginning.

The demon core of the old demon of Montenegro is of the same quality as that of the fire beast Neidan, and such a bowl-sized piece is enough to quench the sword embryo.

"Master, I can begin to reintegrate the old demon body. This old demon body is embedded in the Great Black Mountain, and I need about five Spirit Inner Dan to assist in order to roughly fuse and repair it, and then get out of the Great Black Mountain. ”

At this moment, the ghostly voice sounded in Meng Chen's mind.

"Good. ”

Meng Chen immediately turned over his hand and took out five spirit inner pills that could be absorbed by the ghosts, and placed them on top of the largest old demon core.

"Buzz!"

An invisible force was released from the demon core, enveloping one of the spirits.

Almost at the same time, the shattered old demon cores scattered everywhere immediately began to tremble slightly, and then flew up one after another, reintegrating towards the largest demon core.

"Meng Chen, let's go outside and wait, so as not to affect your ghost servant to reintegrate the old demon body. ”

Yan Chixia on the side greeted Meng Chen, and then the imperial envoy of the three series of sword embryos flew outside.

"Hmm. ”

Meng Chen nodded in agreement, and also summoned the dual-system sword embryo and followed behind Yan Chixia to leave.

Soon, the two were back in the canyon.

At this time, the jet-black gravel that had been shattered by Yan Chixia's eruption had already risen from below the canyon one after another, converging towards the old demon body.

That's not all, even the remnants of the old demon clones that were originally in the "Wanling Cave Mansion" and destroyed by Meng Chen also flew back one by one, and together with those jet-black gravel, they merged into the old demon body.

"We went outside the Great Black Mountain and waited. ”

Meng Chen glanced back, and then beckoned Yan Chixia to continue flying out.

He had already told the ghost before that after fusing the old demon's body, he would send it outside the Great Black Mountain so that Meng Chen could temporarily put it in the spirit interface.

Flying all the way, the wreckage of the clones that gathered towards the old demon's body were all under the control of the ghost, and they took the initiative to avoid the two.

Soon, the two left the Wanling Cave Mansion and came outside the Great Black Mountain.

As far as the eye can see, the rich black fog that fills the entire Great Black Mountain at this moment has begun to slowly dissipate, and the entire Great Black Mountain is much brighter than before.

"Boom ......"

The Great Black Mountain, which was originally silent, suddenly let out a violent tremor, and the black rocks on the top of the mountain crumbled one after another, rolling down towards the foot of the mountain below.

It lasted for tens of seconds before the tremor stopped.

Through the connection with the ghostly mind, Meng Chen found that just at the moment of mobilizing the old demon's body, two of the five spirit inner pills he left behind had already been consumed into a pile of powder.

After a few minutes of silence, Oni Li began to consume the power of the third spirit inner pill, and then mobilized the entire old demon body with all his strength again.

"Boom ......"

This time, the tremor was even more violent, and the range of the summit of the Great Black Mountain, which was twenty or thirty miles in diameter, actually began to bulge slightly, as if something huge was about to break free from below.

The second tremor lasted more than a minute and then stopped again.

Meng Chen sensed it, and in this short period of more than a minute, the power of the fourth spirit inner pill was completely consumed.

After the second tremor subsided, the ghost had rested for more than a moment before he began to consume the last spirit Neidan.

"Boom...... Boom Rumble ......"

This time the shaking was more violent than the previous two times, and it was obvious that the ghost was planning to take the old demon body out of the Great Black Mountain in one go.

After about dozens of breaths, the peak of the Great Black Mountain completely collapsed, and a section of black and translucent spar peaks emerged from the rolling rubble.

After the beginning, the subsequent process was much faster.

The spar peaks are like a giant beast out of the quagmire, quickly rising upward, rising, and rising!

100 zhang, 300 zhang, 500 zhang......

"Boom!"

A black spar mountain with a height of thousands of feet finally broke away from the peak of the Great Black Mountain.

At this moment, Meng Chen and Yan Chixia, who had retreated to a few miles away from the Great Black Mountain, couldn't help but glance at each other, and each other's eyes showed shock.

After the old demon's body is completely separated from the Great Black Mountain, the two of them can really get a glimpse of the old demon.

I saw that this thousand-zhang high giant peak has a diameter of more than ten miles at the bottom of the peak, and even if it is the peak, it is more than one mile in diameter.

"This old demon of Montenegro is really 'the birthday boy hanged himself, and he is tired of being crooked!'"

Yan Chixia smiled, her mouth seemed to be muttering to herself, and she also seemed to be talking to Meng Chen.

"Well, the old demon of Montenegro is so huge, if he hides in the Great Black Mountain and doesn't come out, relying on the power of the Great Black Mountain, he can set too many traps, so that we can't get close to his body......"

Meng Chen also nodded slightly and said with emotion.

"Hahaha...... There's no way, the old demon is afraid that he will be tired of living too long, and he will die to find excitement, so he will open up such a 'Ten Thousand Souls Cave Mansion', so that we can easily reach his original place! Hahaha......"

Yan Chixia glanced at the foot of the Great Black Mountain, which originally belonged to the entrance of the "Wanling Cave Mansion", and let out a burst of laughter.

At this moment, the original Wanling Cave Mansion has completely collapsed and disappeared, and the words "entering the cave seventeen or eighteen, leaving the cave seventy or eighty, and ten thousand souls are dead" at the entrance of the cave have long been shattered and I don't know where they went.

"Hmm. Meng Chen nodded again, and then a smile appeared on the corner of his mouth, and said, "Brother Yan, my ghost servant has found the treasures of the old demon and is transferring them out......
