Ling Xiao stood on the hillside and looked in all directions, this small world is very vast, you can't see the edge at a glance, but it exudes an ancient and mysterious atmosphere.

"Huh, it's not the real world!"

Ling Xiao suddenly felt a shock in his heart, and there was a hint of essence in his eyes.

A strange aura fluctuation appeared on his body, his heart was moved by Ling Xiao, his eyes seemed to be covered with a layer of seven-colored light, and the world in front of him instantly became different.

Bang!

The vast earth, mountains, and ancient trees all disappeared, and in an instant they turned into a vast flame, and the flames were so fierce that they seemed to burn everything to ashes.

Ling Xiao could feel the incomparably hot breath, but as his mind moved, the sea of fire in front of him disappeared in an instant, and an ancient primeval forest appeared, full of vitality and mysterious exotic flowers and plants.

The small world in front of him seems to be able to change with the change of Ling Xiao's mind, which is very mysterious.

Only then did Ling Xiao understand that the seventh floor of this Danshu Pavilion was not a small world, but a mental realm hidden between the virtual and the real.

"Is this the heart realm condensed by the Mixed Yuan Heart Pill Sutra? It seems that Danfu Mountain has really obtained a lot of inheritance from the Sun Moon Dan Sect!"

Ling Xiao thought secretly in his heart.

When ordinary people enter here, it is difficult to find that this is a mental realm, and even if they can find it, there is no way to let the mental realm change as they wish.

Ling Xiao had obtained the inheritance of the Mixed Yuan Dansheng, so when he urged the heart realm, he found that this small world was clearly the heart realm of a powerful and powerful person.

"Interesting, the sixth layer space has a Dansheng Dao Fruit that contains the origin of the Dan Emperor, and this seventh layer space is another heart realm, and the heritage of Danfu Mountain is really not to be underestimated!"

Ling Xiao thought secretly in his heart.

Rumble!

Ling Xiao's powerful mental power spreads out, spreading towards this small world, Ling Xiao's cultivation is too humble and his mental power is very strong, and now he has obtained the Mixed Yuan Heart Dan Sutra, with the inheritance of Dan Dao and Fu Dao, under mutual confirmation, Ling Xiao's mental realm is also becoming more and more powerful, although it has not yet reached the realm of manifestation, but to a certain extent, it already has the power to interfere with the truth.

Ling Xiao wanted to check what secrets were hidden in this small world.

After all, Danfu Mountain regards the seventh layer as the forbidden place of Danshu Pavilion, even the genius disciples of Danfu Mountain are not qualified to enter, and it must contain very important treasures.

"Hey, Ling Xiao, something is wrong with this small world! this doesn't seem to be the real small world!"

Zhao Ritian, who was hiding on Ling Xiao's clothes, did not appear, after all, sneaking into the seventh layer, he was also a little weak-hearted, and naturally became extremely cautious.

Moreover, hiding on Ling Xiao's clothes did not affect his observation of everything in the seventh layer of space.

"You've discovered it too, this should be a powerful man's heart!"

Ling Xiao did not hide Zhao Ritian, and said with a slight smile.

"The Heart Realm? Could it be that the Heart Saint is left behind by a Heart Saint powerhouse? The legendary Heart Saint can create things in the void, kill people with thoughts, and his strength is unfathomable, it is very difficult to realize the Dao Heart Saint, not much easier than the sanctification of the physical body!"

Zhao Ritian's eyes lit up, and he transmitted the voice to Ling Xiaodao.

"You're right! This should be the Heart Realm of a Heart Saint, but even if there are any treasures in the Heart Realm, I'm afraid they have already been obtained by Danfu Mountain, and they left this Heart Realm as the seventh layer of the Danshu Pavilion, I can't guess what their intentions are!"

Ling Xiao nodded.

"What's the point? Isn't that a simple thing?"

Zhao Ritian smiled proudly.

"Oh, you know?"

Ling Xiao asked with some surprise.

"Of course I know! Using the Heart Realm as the seventh layer of the Dan Book Pavilion is both a test and an opportunity! If the disciple of Danfu Mountain has the opportunity to enter the seventh layer and understands the mental strength, it means that this disciple has the opportunity to prove the Dao Dan Sage with the mental strength, you must know that the way of the Heart Pill is incomparably mysterious, and the alchemy in the mental realm with mental strength can be countless times faster than that of ordinary alchemy, and the effect is better!

Danfu Mountain left this Heart Realm, it must be to select a successor! I guess this Heart Realm must contain the origin of the Heart Dan Dao, let's go and find it, maybe we can get a lot of creation!"

Zhao Ritian said very confidently.

"Can you try it!"

Ling Xiao's eyes flashed, and he nodded.

Although Ling Xiao has condensed the heart realm, cultivating the way of the heart pill will get twice the result with half the effort, but if you can find the origin of the heart pill contained here and devour it, it will also be very beneficial to Ling Xiao's heart realm.

This small world may be very vast, but it is not difficult for Ling Xiao, as long as he urges the Mixed Yuan Heart Pill Sutra, it should be easy to find the origin of the Heart Pill Dao.

Sou!

Ling Xiao jumped up, volleyed into the void, hunted in white robes, and flew towards the depths of the small world.

According to the induction of the Mixed Yuan Heart Pill Sutra, the origin of the Heart Pill should be in the depths of the small world.

Thundered!

The mind is changing, looking mysterious, one moment the flames are monstrous, the other the waves are rising, the towering ancient trees form an ancient forest, and the other they turn into endless galaxies.

If ordinary people enter the small world, I am afraid that it will take a long time just to decipher the changes in the mental world.

And Ling Xiao didn't have any worries, he stood in the void, his expression was extremely calm, looking at the changes in the mental realm below, as if he was standing in the perspective of a bystander, not stained with dust, it couldn't affect him at all.

In the end, Ling Xiao landed on a barren mountain.

The barren mountain is only a few dozen feet high, without any vegetation, it is all bare rocks, showing a black-brown color, as if it has been burned by fire.

Standing on top of a barren mountain, Ling Xiao felt as if he was standing at the center of the world.

In front of Ling Xiao, there is a quaint stone house, and there is a black stone tripod outside the house, which looks more than one person tall, and the stone skin is mottled, with a sense of vicissitudes of time.

Except for the stone house and the stone tripod, there is nothing else on the barren mountain.

"Heart Pill Origin, isn't it here?"

Ling Xiao's heart moved slightly, his gaze fell on the stone house and the stone ding, and there was a strange light in his eyes.

He could feel that the stone house and the stone tripod seemed to be very ordinary, but they didn't seem to be entities at all, and they didn't exist in this void, as if they were separated by endless time and space.

Ling Xiao stretched out his hand, wanting to touch Shi Ding.

Airplanes!

A ripple-like wave of water spread, and Ling Xiao's hand directly penetrated the stone tripod and touched the air, just like a phantom.
