Day after day, cultivation is always boring, and there is never any mercy on this crowded path of Shura, and there is no room for slackness.

The cultivation on the top of the mountain has always been consistent, and Lu Chen's control of this body has gradually returned to its former peak. At least, now he no longer feels strange and uncomfortable, everything can be easily controlled, even if it is not up to the requirements of purgatory, but it is not too bad. And with the current Lu Chen, if he didn't take into account the gap in the cultivation of the secret method, he might not be able to defeat him even if Mu Shuangying did it with all his might.

It is the prosperity of flesh and blood, and it is very comparable.

"Freak!"

Mu Shuangying pursed his lips and complained, and the original cultivation realm was very different, but he didn't want to get rid of the secret method gap, and everything else was almost the same, and even Lu Chen's blood qi was even worse than her. The Dao method is ever-changing, but the white fox mark in Mu Shuangying's hand fell, and Lu Chen could break it with only one punch, although the skin was burned and the flesh was opened, but it was not a big trouble.

"I'm going to take you somewhere today. ”

Stepping out of the cold pool ice spring, both of them steamed up the water traces on their bodies.

There are still more than a month to end the cultivation here, and Lu Chen's secret method can only reach a small level, and the Lost Chaos Step is a little weaker than Mu Shuangying, and he only comprehends the gossip sixty-four changes and six out of fifty, which is not completely transparent. However, Mu Shuangying had already comprehended it and moved towards the seventy-two earths.

"Where are you going?"

Lu Chen was a little puzzled.

He hadn't walked all over the top of this mountain, so he naturally didn't know.

"Great place!"

Mu Shuangying only laughed, pulled Lu Chen, and walked towards a higher place behind the dead wood forest.

Although Lu Chen has never been here, he can also see the ice and mist from afar, the towering ancient trees are like tops like covers, the branches are staggered like nets blocking the sky, and the snow is like jade, which is really magnificent. When you get closer, you can feel people like ants, ancient trees are towering to the sky, and there is a wonderful charm flowing in it, and this dead ancient tree is also such a treasure, only their realm can not be understood.

"Is there something wrong with this ancient tree?"

Lu Chen looked at it for a long time, but he didn't find any benefits.

A dead branch is a dead branch, not even a leaf, even though it is quite strange in itself, but the dead branch is constantly broken, Lu Chen has already tried, it is more tenacious than gold and iron. If you can't get it like this, it's not a good thing, you can just look at it. To say that the whole ancient tree is uprooted, it is a bit fantastical.

"This tree is wonderful, but it's not a good place for me to say, come with me. ”

Mu Shuangying laughed, and led Lu Chen around the knotted Gugen, climbed over the rocks, and reached the edge of the cliff. And at this point, you can feel a little hot, it is the breath that is too blazing in the ancient cave, and the top of this mountain is steamed and dry.

And looking around, there is a fire spitting and shining under the rocks, and it is impossible to see clearly from here.

"What's that?"

Lu Chen was puzzled and asked.

Mu Shuangying didn't answer, only pulled Lu Chen around the rocks and came to the entrance of the cave.

The scorching waves of air rushed to the face, which was really unbearable. Lu Chen is okay, his blood and qi are strangely condensed and thick, and he has the blood of the Demon Emperor to refine his body, and he has access to hundreds of limbs, so he is not afraid of anything. Only Mu Shuangying's face was a little red, obviously uncomfortable from the fire vapor swallowed by this hole.

"You have more flesh than I am, see if you can go deeper and see what treasures are hidden in it. ”

She hugged Lu Chen's shoulder, her face full of smirks.

"This dangerous mountain is not an ordinary mountain, the top of the mountain is covered with snow all year round, but there is such a place. That wolf guy never told you and me, and let us stay here and leave on our own, must have made sure that we couldn't get in. But your blood is so strong, and you can bear the heat even more, so you might as well give it a try. In a month's time, that guy should come back, and you and I won't have a chance then. ”

"This..."

Lu Chen opened his mouth, a little hesitant.

He turned his head to look at the entrance of the cave, which seemed to have been built by man-made stones, and the fire was flowing and red, and it was obvious that the temperature was unusual. The surging blood qi can indeed withstand stronger heat, and the cultivation is enough, but the cultivation of Mu Shuangying's four royal peaks cannot withstand it, and Lu Chen is really a little unsure whether he can withstand it.

"Give it a try, if it doesn't work, quit and talk about it later. If you can really go down, you can't say that it is a good treasure. Besides, I didn't bring you here to harm you, but only because there could be a chance in it. If you can really get it, I won't rob it, just give me some benefits at will. ”

Mu Shuangying said again.

"What benefits do you want?"

Lu Chen glanced at her, and his heart was quite weird.

Then he only grinned and shook his head slightly.

"If you really get good, and I don't want anything, you can just promise me something. ”

"What if you can't get it?"

Lu Chen pursed his lips and turned his head to look at the entrance of the cave.

The red was a little too dazzling, and Lu Chen was really a little uneasy. There are too many traces of human beings seen at the entrance of this cave, and there is no need for Mu Shuangying to say more, this place must be caused by purgatory. However, no one can guarantee what is hidden in it, and the fierce wolf has never mentioned it, probably because he finds it inconvenient for them to know.

"If you can't get it... Then there is no way, I can't ask you for anything, after all, it didn't bring you any benefits. ”

Mu Shuangying only said casually, looked around again, and began to urge.

She really wanted Lu Chen to go in and give it a try, but she couldn't guess what kind of plan she had. Lu Chen didn't know either, but Mu Shuangying swore with his Dao heart, as he said before, if he could get the treasure, he would only promise her one thing, and he would not harm anyone.

"If so, what will I promise you?"

Lu Chen asked again, a little vigilant in his heart.

He knew in his heart that Mu Shuangying would not harm anyone, but it was really a little weird like this.

"I naturally won't harm you, you believe in me. Moreover, you may not be able to get it yet, and if you say it now, and you don't get it, you will waste your saliva. On the other hand, I also had a Dao heart vow before, if I really hurt you, I will not die well! ”

Mu Shuangying looked at him and laughed.

Lu Chen was suspicious in his heart, stepped forward a few points, his mind turned, and finally agreed.

There is nothing bad about going, but if you don't work, you just quit. And if you can really get the treasure, only Mu Shuangying knows about it. Even if the wolf comes back, he may not be able to find it, and even if he finds it in the future, he probably won't be able to find his body. In this way, he also promised Mu Shuangying that he had a Taoist oath as a constraint, and he couldn't end up together.

"I've gone down a few times, and I've walked a hundred feet deep, but I still haven't seen the end. The fire inside is too bright to see, but probably not very deep. ”

Mu Shuangying smiled brightly, but he always looked like a fox, which was suspicious.

Lu Chen glanced at her, and then went directly into the cave.

When he stepped in, he hesitated for a moment, after all, the black knife was not in his hand. On that day, the mad demon fought with the wolf, and the black knife was lost in the crumbling hills. Mu Shuangying had been looking for a long time, but he couldn't see it, and now he had no sharp weapon in his hand.

Without a knife, his sword skills were also abolished.

People say that the general trend of attack is that the grass and trees are soldiers, but Lu Chen has not yet reached this realm. Killing the Nine Styles is the simplest of the road, which contains infinite wonders, and the more you comprehend, the more profound you feel. I don't know how long it will take to reach the realm of transformation.

"That's it, just give it a try..."

Lu Chen sighed secretly before stepping in.

There is a black stone platform at the entrance of the cave, and there is a staircase spiraling down on one side, which is not exquisite, but it is stable enough, and it also looks jet black. The road descends, the wider the mountain, the heat waves, the scene is distorted, and when you look down, you can see a red rolling, as if an endless sea of fire is burning and boiling in it. I walked for a long time, and I went around a lot, and it was a hundred feet deep, but I still didn't see the end. And at this point, Lu Chen also felt unbearable, his clothes in animal skins were charred black, and they were exuding a scorching smell, which was really a little pungent.

Looking down again, a black dot is faintly visible.

"Is there really something?!"

Lu Chen was a little startled, estimated the distance again, and hesitated slightly.

Too deep.

And by this point, the heat has become so terrible that it is impossible to determine how far it will go. Where the black spot is, there are probably hundreds of zhang, and now only here the animal skin clothes can not bear it, if it goes down again, even if the body can resist, probably the animal skin will be burned to ashes.

When you go out at that time, you will have to be smooth and uncovered.

"Well, she took the risk to take me up the mountain, and she took the lunch as her adventure. It's just a thing, take something and promise her!"

Gritting his teeth, Lu Chen only comforted himself like this, and continued to go down.

The original black stone gradually turned red, and the soles of my feet stepped on it, and I only felt a burning pain. After falling fifty feet, the black dot became more obvious, and it was obvious that the distance estimated earlier was not accurate. Even now, I can see clearly that the black dot is slender, not such a strange thing, and this shape also makes Lu Chen feel familiar.

It's a knife!

The slender Tang knife is unusual, just like the knife type that Lu Chen used to hold.

"Weird, how can this be?"

He was puzzled in his heart, and after calculating the distance, it was probably only a few dozen zhang.

However, at this point, it was extremely difficult to go down, and his animal skin clothes were completely blackened, burning and brittle, and only covered his body. As soon as he shook his body, a large amount of ashes fell. It only takes two more steps, and there is nothing left to hide. However, it doesn't matter, after all, Lu Chen knows very well that his appearance has long been accustomed to Mu Shuangying, but the heat wave is too much, burning his skin and flesh, and it is difficult to open his eyes.

"What's wrong? What do you see the black dot?"

Mu Shuangying came to the stone platform at the entrance of the cave and looked down, but he could only see a fiery red, and it was burned and distorted everywhere, and he couldn't even see Lu Chen's appearance clearly.

"Knives. ”

Lu Chen replied, and went down a few points.

Mu Shuangying was probably stunned in place, she never thought that there was a knife hidden in this ancient cave.

After another moment, Lu Chen had to stop and swallow the pill to recover his injuries. The burning pain was so unbearable that his black iron mask had to melt, and the Demon Emperor's blood-hardened body had reached its limit, almost burning. And in the depths here, it is probably still cold and windy in the outside world, but it is like this in the mountains, which is really a bit weird.

Hot inside and cold outside, in such an extreme environment, you can even feel the chill coming through the stone wall.

"There's something in this mountain wall too. ”

Lu Chen knocked on the mountain wall on the side, and the sound was not normal.

The width of the mountain's belly here is only about two or three zhang from the surface of the mountain. With such a thickness, how can it hold the mountain without collapsing, Lu Chen does not understand, and it may have something to do with the things in the mountain wall. And looking down again, you can vaguely see that there is a misty red rainbow at the bottom as a line and pointing upward, just in the center, only a little distance to disappear, no more than a zhang high.

However, where the red rainbow was, there was a knife suspended in it.
