In the heavenly dome, ordinary eyes cannot perceive, and there are countless stars of light, which are spilling from the five planets. Star power fills the void, and its volume gradually thickens. If you don't distinguish such a situation in detail, you will never be able to detect it at ordinary times. However, under Ling Yun's careful observation, he soon discovered this.

When I came to the blessed land that had just been promoted to the cave sky, I saw a breath rushing into the sky from a distance. That breath twisted into a pillar of air, stirring the void star power, sucking the power of countless stars into it, and I don't know where it went.

After silently calculating in his heart, Ling Yun knew the details: "These caves are just the beginning, and they lack foundation because they are promoted too quickly. Although it is supported by the leylines, it also needs to absorb the Void Vitality to accumulate the Origin. It's going to be going on for a while, but it's normal!"

While calculating, he flew towards the location of the cave sky, and at the speed of Ling Yun, he soon came to the cave not far away. The cave that had just stopped its body and was hidden in the void showed a little bit of shape at some point. From a distance, I saw a mirage-like illusion quietly emerging in mid-air.

Ling Yun couldn't help but stop and watch, and the scenery in front of him changed, revealing a scene of birds singing and flowers. Seeing the scenery in the mirage, Ling Yun couldn't help but blurt out: "Good view!"

Raise your eyes and look around, the scenery of the Eight Transformations Mirage is no longer the world, there are many spiritual roots and immortals swaying in the wind, a strange flower and grass are lined up all over, strange pines and strange rocks are craggy, there are birds and birds dancing between the cliffs, there are beasts running in the valley, among which there are spirit apes wandering, and strange beasts climbing.

Ling Yun knew that this was the cave heaven that had been promoted from the blessed land. This cave is a great blessed land, which was opened very early, and it has been operated for almost thousands of years. The interior is rich in species and vibrant, and it is a hundred times stronger than the mountain range attached to the cave sky. All the causes are combined in one place, which is why this great blessed land has been created, and it has become the blessed land that was the first to be promoted to the cave heaven.

"It seems that it was born early, and it is still very advantageous! After such a long time of operation, this great blessed land has also accumulated some heritage. However, this is also related to the fact that the power of the stars has gradually become stronger recently. With Star Power participating in the evolution of the blessed land, it will allow it to establish an internal circulation earlier, which is why it can be promoted to the Cave Heaven so quickly. Ling Yun looked at the scene that appeared in the mirage and thought silently.

At this moment, a divine rainbow shot out from the mirage and turned into a bridge of light, extending to Lingyun's feet. In the distance, Ling Yun saw that in the mirage vision, at the other end of the Divine Rainbow stood the former and present Lord of the Blessed Land, and the current Lord of the Cave Heaven.

Seeing this, Ling Yun did not hesitate and stepped on the light bridge. Before he could walk, the flybridge immediately wrapped up in his figure and flew towards the mirage. In a flash of lightning, a burst of smoke and light disappeared in front of him, and when he stopped and stood firm, he raised his eyes and saw the man standing ten feet away.

"Yu'er, it seems that your side is doing very well, and you have been promoted to Dongtian so soon!" Ling Yun greeted the man opposite.

Yu Er greeted Ling Yun, and when she heard his words, she couldn't help laughing: "Of course, I have put a lot of thought into this place over the years. If it weren't for that, I'm afraid I wouldn't have been promoted to Cave Heaven so quickly!"

"Indeed!" Ling Yun laughed, "If you don't care about it, you can see the speed of the promotion of the Cave Heaven through the blessed land!" Speaking of this, Ling Yun paused, and poured cold water on Yu Er: "Although you are the first to be promoted to the Cave Heaven here, you must also be careful - the promotion of the Blessed Land to the Cave Heaven is too fast, and the self-circulation is not perfect, and your Cave Heaven may fall into the dilemma of a pause in evolution in the future!"

This is not that he is alarmist, although the blessed land is a space of its own, its self-circulation is not perfect, whether it is the ecological cycle, the vitality cycle, the law cycle, etc., it has not been established, everything has to rely on external support. In order to elevate the blessed land to a cave heaven, it is necessary to establish a perfect circulation, and the interconnection of nature, ecology, vitality, laws, etc., into an independent and self-consistent circulation system. If the seedlings are rashly promoted, the self-circulation system of the cave sky is imperfect, resulting in too many loopholes, and the evolution of the cave sky will come to a standstill, and even more seriously, it may lead to the entire collapse of the cave sky.

In this regard, after Yu Er listened to Ling Yun's warning, he laughed shyly, with a triumphant look: "You don't know this, I got another arm to help me establish a self-circulation system, so I'm not afraid that the evolution of the cave sky will come to a standstill!"

"Oh?" Hearing Yu Er's show-off, Ling Yun asked suspiciously, "What did you get that could actually help you build a cycle?"

Speaking of this, Ling Yun couldn't help but secretly guess, "Could it be the Innate Spirit Treasure?" The first thing he thought of was this kind of thing, "The Innate Spirit Treasure has infinite mysteries, and suppressing the heavens and the earth is idle, not to mention suppressing a single cave heaven?

But he thought about it: "How rare is the innate spirit treasure, even the Houtu has not obtained any innate spirit treasure, how can Yu Er get such a rare treasure as the innate spirit treasure?"

After secretly rejecting this speculation, he thought of something else: "If it wasn't an innate spirit treasure, would it be some kind of rare treasure born in the nature of heaven and earth?"

Compared with the innate spirit treasure, he was more willing to believe that Yu Er had obtained some kind of rare treasure produced by heaven and earth. After all, the innate spirit treasure is too rare, and it is good at concealment, so it is impossible to find a trace. The only possibility is that it is a heaven and earth treasure that is slightly inferior to the innate spirit treasure.

After a few guesses, Ling Yun was quite curious about what Er's got from, but he didn't explore too much. However, Yu Er himself is also a generous person, and he did not hide it from Ling Yun, and directly took him to the center of the cave and saw the thing that assisted him in establishing the cave heaven cycle.

At first glance, it was a very inconspicuous thing, and from a distance it was just a huge stone. But it is this inconspicuous boulder, but there is an extraordinary rhyme faintly flowing on it.

The boulder was about seventy or eighty feet high, as if it were a hill towering over it. Its shape is irregular, the top is small and the bottom is large, as if a pile of chaotic stones is piled up at will, its whole body is yellow and black, the stone is rough, as if it is a waste stone that can not be carved. If you look closely, the more you look closely, the more extraordinary it becomes. There was a faint imperceptible rhyme flowing over it.

Looking at the nameless boulder, Ling Yun couldn't help but be secretly frightened by its uniqueness: "Although it is said that the 'Tao is in all things', there are too many 'Dao' on this boulder, and it has even reached the point of influencing the outside world and making people perceptible, I don't know how this thing is formed?"
