In a blink of an eye, half a month has passed.

In this half month, the aura of heaven and earth in the cave mansion where Li Yunfeng cultivated gathered from time to time, which was a manifestation of Li Yunfeng's imminent breakthrough realm.

Jiang Xuan and the others, as martial cultivators, could naturally feel the different breaths around them, and they were also secretly surprised.

The master is not the master, and the cultivation can cause the movement of the aura of heaven and earth, and he has never heard of this kind of thing before.

In the cave, Li Yunfeng closed his eyes tightly, his whole body exercises were running rapidly, and the aura of heaven and earth was also roaring with the operation of his body!

At this moment, the aura of the entire Jiang family was completely rioted, and it quickly converged towards Li Yunfeng.

"This!"

Jiang Xuan felt the spiritual power riot around him, and his heart was very shocked.

It was only a small-scale aura movement before, which was already surprising enough, but he didn't expect that now such a large range of heaven and earth aura of the entire clan was rioting, which made him very surprised.

The rest of the Jiang family naturally felt this situation at this time, and at this time, they looked at Li Yunfeng's cultivation cave halfway up the mountain, and their eyes were full of fear and reverence.

In the cave, the endless aura of heaven and earth converged into Li Yunfeng's dantian spiritual root, and the dantian gradually filled, and the yin and yang qi swam like a spiritual snake in the dantian!

When the dantian could no longer contain spiritual power, Li Yunfeng knew that the opportunity to break through the level had come.

Li Yunfeng let out a low roar, and the spiritual power of his whole body also surged to the dantian, breaking through the level strongly!

"Boom, boom!"

It was as if there was a real explosion in the body, and it boomed.

With the impact of spiritual power for an hour, the void and real dantian in the human body seemed to crack at this moment.

Through the cracks, it seems that there is a Dao foundation looming.

"It's going to work!"

Although Li Yunfeng was sweating at this time, a smile appeared on the corner of his mouth, and he had a different feeling when he broke through the foundation building realm for the second time.

Li Yunfeng continued to attack along this crack, the crack became bigger and bigger, and after another half an hour, a cyan Dao platform seemed to have come from ancient times, floating in the dantian that had been expanded by nearly half!

It's done!

Li Yunfeng felt the spiritual power of his whole body skyrocketing several times, and his heart was unwavering.

He who had reached the realm of the Demon Emperor still had a feeling of weakness at this time, and it was difficult to adapt to it for a while.

However, he is also fearless now, and now he should be completely fearless in the face of the hot weapons of the secular world.

In the face of the so-called martial arts cultivation sects and families, they should also be in a state of crushing, even if these so-called martial arts cultivation families really have so-called extreme realm powerhouses, it is still not enough.

Li Yunfeng smiled faintly, and prepared to go out of the mountain and go down.

It's just that the moment he stood up, his body shook violently, and he almost fell directly to the ground.

Li Yunfeng's face changed greatly, and he sat down again, and a trace of blood overflowed from the corner of his mouth.

Li Yunfeng's face was pale at this time, and sweat was like rain.

"What's going on?"

Li Yunfeng hurriedly checked the state of the dantian, because the abnormalities just now were all caused by the dantian.

When his divine thoughts penetrated deep into the dantian, Li Yunfeng's face suddenly changed greatly.

The cyan platform that seemed to have come from ancient times had several cracks at this time!

And the crack is still expanding, and it won't be long before it collapses completely.

What's going on?

Li Yunfeng forcibly calmed himself down.

After a while, Li Yunfeng opened his eyes.

He muttered, "Suppression from the Great Dao!"

Is this the reason why there are relics of immortal cultivators on the earth, but there are no real immortal cultivators?

Li Yunfeng looked through the cave at this time, looking at the top of the cave, his gaze seemed to penetrate the top of the mountain, reaching the sky!

"Just Earth Avenue, you also want to suppress me!"

After finding out the reason for the rupture of the Dao Foundation, Li Yunfeng's eyes burst out.

At this time, Li Yunfeng stood up directly, walked out of the cave, and then came to the top of the mountain, sitting cross-legged on the top!

"Earth Avenue, Little Doyle!"

Li Yunfeng looked at the sky and smiled coldly.

Although the Great Dao is formless and unconscious, it is just a rule, but it will cause chaos in the rules for various reasons, which will lead to chaos in the Heavenly Dao.

Immortal cultivators sometimes benefit from cultivation because of changes, and some changes will bring devastating blows to immortal cultivators.

Just like this situation on Earth, because of the changes in the Heavenly Dao, the immortal cultivators have completely disappeared, and only some weakened versions of the martial cultivators remain.

However, these problems are not difficult for Li Yunfeng, who has reached the realm of the Demon Emperor, and they can be solved!

After some deduction by him, he believed that the yin and yang qi in his body combined with the five elements viscera, and then through some techniques of cultivating the immortal world, he could be self-contained, so as to successfully build a foundation!

However, this method is only suitable for him, and several factors that can successfully build the foundation are unique to him.

Yin and Yang Chaos Formula!

Refining the Yin and Yang Qi of Heaven and Earth!

A perfect body is also needed!

None of these others possessed, only he had them all.

But it's too early to think about this, even Xue Yiyi, in this earth where the aura is dry, the cultivation will not be too fast, so it is too early to think about these things.

After thinking clearly, Li Yunfeng reorganized the Daoji again.

Because the spiritual power required for cultivation was sufficient, Li Yunfeng did not change his spiritual power when he reorganized the Dao Foundation this time.

However, there was no movement of spiritual power, but the feelings of the people in the Jiang family were indeed stronger.

Although this is not a change in spiritual power, but a cover-up of rules.

When Li Yunfeng used the technique of deceiving the sky, the Jiang family's one-third of an acre, the unconscious avenue of heaven and earth was frantically looking for the person who covered the sky.

So this time it was a riot of rules, and ordinary people didn't feel it, but the Jiang family, a martial arts family, really felt that the end of the world was coming.

Moreover, everyone in the Jiang family found that the closer they got to Li Yunfeng's cultivation position, the stronger this feeling became.

Obviously, it was caused by Li Yunfeng's cultivation.

Although they knew that it was caused by Li Yunfeng, everyone was not afraid from the bottom of their hearts, but the avenue was always the avenue, and everything was under the avenue, and everyone was still in fear.

At the same time, they were even more in awe of Li Yunfeng in their hearts.

Just the movement of cultivation can make the people of the entire clan like this, which they couldn't imagine before.

This process lasted for nearly three hours, Li Yunfeng reopened his eyes, the corners of his mouth were also overflowing with blood, and his eyes were full of bloodshots.

Obviously, this process is not simple, and Li Yunfeng's cultivation is still too low after all.

However, in the end, he succeeded in entering the realm of foundation building.

At this time, after the cyan Dao platform underwent cracking and reorganization, it was up and down in the dantian, and it felt more tenacious than at the beginning.

After breaking and standing, Li Yunfeng's cultivation has improved a little.

And what made him even happier was that the dantian in his body was a world of its own, existing in the world of the earth, and it was independent, and the rules of the earth avenue could no longer affect him.

Li Yunfeng was very satisfied, the Earth Avenue was originally the lowest level of the Great Dao.

If he changes his peak, where does he need any tricks to deceive the sky, just directly use his own rules and forcibly change the rules of the earth, where may it affect him.

However, this also has benefits, the dantian in the body is a realm of its own, independent of the ten thousand worlds, and I have never heard of it in the immortal cultivation world, and I don't know what it will develop into in the future!

Li Yunfeng is looking forward to this!
