Li Lanyu has been practicing the light skills of Tiyun Vertical for a day in a row, and she has made great progress, and she can already fly to the height of two-thirds of the cliff, as long as she increases the speed of ventilation, she can completely fly up the cliff.

It was getting dark, and Lin Muyu and Lin Yuyan hadn't come back yet. Xiaoxiao, Lin Cui, Li Lanyu and Fang Xiaoyu waited for a while, until it was completely dark, and then returned to the Sansheng Nunnery.

Although they were all a little worried about Lin Muyu and Lin Yuyan, there was no way, this cliff could fly over except for the Jingxu Master, that is, Lin Muyu and Lin Yuyan could fly over, and the light skills of the four of them had not reached such a high height, and they couldn't go up the cliff if they wanted to.

And Master Jingxu is still in retreat at the moment, and it is impossible for the four of them to disturb Master Jingxu's retreat for this matter.

What's more, Lin Muyu and Lin Yuyan are not children, even if they spend a night in the deep mountains, nothing will happen, and it is impossible to be eaten by wolves, their martial arts are not ordinarily high, they both have second-level internal strength, and Tiyunzong's light skills are stronger than any of them.

However, it is impossible for them not to worry about it at all, Lin Muyu and Lin Yuyan must have encountered something, or encountered danger, otherwise it is impossible not to return at night.

The one who worries her the most is Li Lanyu, her heart is like fifteen buckets of water, seven up and eight down.

Li Lanyu went outside the door for a while, and then outside the house for a while, but she didn't see Lin Muyu and Lin Yuyan coming back.

In the evening, the four of them had no intention of eating, first, now that Lin Muyu was not there, they didn't want to eat roast beef, and second, they were so worried that they couldn't eat.

However, their worries were actually superfluous, Lin Muyu and Lin Yuyan did not encounter danger, not only did they not encounter danger, but they also got a great opportunity.

First of all, the two of them caught two white sables, which were very cute, and then the white mink took them to the bottom of a cliff and pulled out a lot of ginseng, which are thousands of years old, but they are precious.

I also picked a lot of Ganoderma lucidum, which is also a very precious thing, and also picked a big mushroom, this big mushroom is also terrifying, and it is particularly fragrant.

And just when Lin Muyu and Lin Yuyan wanted to climb the cliff, Lin Muyu discovered a new situation.

He suddenly smelled the abnormality of the air, and suddenly noticed that the air at the bottom of this cliff had a special smell, which made people feel refreshed.

Not only did Lin Muyu smell it, but later Lin Yuyan also smelled it, and she immediately said in surprise: "Brother Lin, is this the aura that is rumored in the rivers and lakes?"

"It should be, although no one has ever seen the aura, but there has always been this legend, if the martial arts practitioner encounters the aura of heaven and earth, it is a great opportunity. Lin Muyu then said.

He only blurted out these words subconsciously, as if he had this concept in his subconscious, and this is the role of the Buddha and Demon System.

"Brother Lin, it's for sure, I just need to take a breath to have a special spirit, which has never been seen in other places. Lin Yuyan said in surprise again.

Lin Muyu also took a deep breath, feeling that this air was indeed very abnormal, and he also felt the source of this aura.

Lin Yuyan also felt it, and she couldn't help but move with that aura, and the two of them came to the back of the rock together, which was the place where the big grinding mushroom grew.

Just now they saw a big mushroom that was so happy that they didn't even notice the change in the air here.

"Brother Lin, this aura must have come from under this rock, maybe there is something good in it. Lin Yuyan said in surprise again.

"Yan'er, your feeling is right, there must be something unusual down there, let's move this rock together. Lin Muyu said again.

So, the two of them worked together to move the big rock, but they didn't move, and the big rock didn't move at all.

This is strange, you must know that Lin Muyu and Lin Yuyan are both second-level internal forces, each of them can lift a big cow, but they can't move a rock together, which shows that this rock is not ordinary.

Lin Muyu and Lin Yuyan glanced at each other, both a little surprised, Lin Muyu looked at the big rock, and suddenly said, "Yan'er, you come to my side." ”

Lin Yuyan immediately came to Lin Muyu's side, and the two of them moved together to push the big rock together, and now the two of them are exerting force on the side at the same time, and the strength is twice as strong as before, and then a clicking sound was heard, and the big rock finally moved.

As long as it moved, it would be easy to do, Lin Muyu and Lin Yuyan worked together again, and suddenly moved away from this big rock.

The rock quickly rolled to the side, revealing a large crater. This pit is more than one person deep, and the aura comes out of this pit.

Lin Muyu looked at the pit for a while, and suddenly said, "Yan'er, let's go in together." ”

Lin Yuyan nodded, and then the two jumped into the pit together, and then a strong aura came to their nostrils.

"Brother Lin, I didn't expect the aura here to be so strong. Lin Yuyan said in surprise again.

"Yes, this aura is a good baby, Yan'er, hurry up and practice, don't waste such a good aura of heaven and earth. Lin Muyu said again.

So, the two of them entered the state of cultivating internal strength together, and soon settled down. Once they cultivated, they didn't know the concept of time at all, and the sky quickly darkened, and they didn't pay attention, and they were still cultivating their internal strength.

After Lin Muyu absorbed these aura, the true qi of the dantian became more active. These true qi were all produced by him after drinking the wine of thyme, and the purity was not high, Lin Muyu had to purify these true qi every time he cultivated his internal strength.

Now with the addition of these aura, these true qi immediately changed, and soon reached a certain level of purity.

Lin Muyu immediately had a feeling of breakthrough, feeling that he was about to break through to the third-level internal force, and couldn't help but feel a burst of ecstasy.

You must know that the higher the level of cultivation internal force, the more difficult it is to break through later, and he has just broken through to the second-level internal force for less than a month, and now he is about to break through again.

This kind of cultivation speed is absolutely unprecedented. After Lin Muyu was excited for a while, he calmed down again, and suddenly thought that there was so much aura here, it was important to absorb the aura first, and there was no need to rush to break through.

Lin Yuyan also felt very wonderful, the aura continued to enter her dantian, and constantly washed the meridians of the whole body, and suddenly there was a warm feeling, like a spring breeze.
