The flow of Qi is endless, the cycle is endless, and the circulation is endless. In the cave, countless Yuan Qi boiled, and the entire space began to expand rapidly. As the cave grows, the void inside becomes thicker and thicker, giving birth to layers of voids.

Just like writing an article, you can only write a short text on a page, and you can't record much more content. But the more paper, the more the content. The void is layered, not only overlapping like paper, making it more indestructible, but also able to hold more 'records' and derive richer content.

Ling Yun felt the changes in the natal cave sky, and silently calculated in his heart. While calculating the evolution process of the cave, the internal circulation structure of the cave was adjusted. Evolving the Cave is like building a city, all aspects need to be considered, and all kinds of issues need to be coordinated.

Generally speaking, the faster the evolution of the cave, the better. The evolution process and expansion speed of the cave sky depend on the accumulated heritage of the cave sky. If you have a strong foundation, it doesn't hurt to evolve a little faster. But if the foundation is insufficient and the evolution is too fast, there will be a big problem.

It's like building a house without laying a foundation, and building a house directly on flat ground. It's fine to build a one-story house, but once a multi-storey house is built, it's not necessarily true that the house without a foundation can be supported smoothly. In the same way, if the evolution of the cave is insufficient, a careless will leave loopholes in the evolution of the cave, which may lead to conflicts of laws and shake the foundation of the cave.

However, if there is something special to suppress during the evolution of the cave, this kind of problem is not a big problem. Lingyun's Dongtian foundation was the World Tree, and half of the entire Dongtian Cycle Law was built on the World Tree, so he didn't need to worry about this kind of problem when he evolved the Dongtian.

It's just that although he doesn't need to worry about the accumulation of heritage, he still has to adjust the structure of the cave from time to time and sort out the laws of the cave to make the evolution process smoother.

As the Origin of the Divine Tree was swallowed by the World Tree, the core of the entire Cave Heaven was like blowing up a balloon, and a huge amount of Origin was rapidly accumulated. Part of the Cave Heaven Origin was hidden deep within the Cave Heaven, and part of it was integrated into the World Tree. With the evolution of the cave, a bright light suddenly appeared in the deep sky, dazzling and brilliant.

In the underworld, a large area of vitality descended, turning into a rich sea of vitality, and the whole cave was filled with fog. Ling Yun inhaled slightly, and that Yuan Qi quickly integrated into his body, turning into rolling mana, circulating around his body, and the entire Yuan Shen quickly began to grow.

As the cave evolved, the World Tree grew, and under its effect, the Nether God Tree in the outside world decomposed faster and faster. After only a few moments, a large branch of the Divine Tree turned into a stream of vitality, and all of it was swallowed by the World Tree and sucked into the Natal Cave Heaven.

Creation saw that Lingyun's cave suddenly expanded from a range of thousands of acres. It even encased the entire sacred tree.

If you look at it from the outside world, there is a hazy charm around the entire place where the ancestral roots of the Divine Tree are located, looming, like a mirage, and it seems that it is about to enter another void level at any time.

At this time, there were earth-shaking changes in the cave: first, many things that had been transformed by Yuan Qi suddenly collapsed, turning into countless Yuan Qi and entangled with each other. Then the entire void in the cave shattered, and the World Tree took root in the void, standing still.

The void in the cave shattered, and the entire cave began to reshape, and countless water, fire, and wind surged out from the center. Instantly transformed into heaven and earth.

In the invisible void layer, with the earth, water, fire, and wind, the layers of void are connected, entangled, or merged, or expanded, or curled up and contracted, forming an extremely complex void layer. These Void Layers combined to form a more solid Cave Heaven Barrier.

The entire cave barrier showed a crystal stone color, and thousands of light colors were refracted from it. At this moment, the entire cave is very different from the original, it is this layer of crystal wall that completely separates the cave from the universe.

Standing in the center of the Cave Heaven, Ling Yun raised his eyes and looked around the entire Cave Heaven, and after staring at it for a long time, he breathed a long sigh of relief: "It's finally done! After the Cave Heaven was promoted to the Little Thousand World, the Earth Immortal Dao began to enter the right path!"

Look at the new changes in the whole world, the vast land has been extended, new mountains and rivers have been born, the earth has expanded, and even some creatures have been born.

Looking at the development of the world, I saw that the original fog was hazy, as if it was chaotic, a strong wind blew by, and the chaotic fog dissipated. In the fog that had cleared, vast expanses of forests, lakes, oceans, and all sorts of life appeared. On the continent in the world, there are many ordinary elixirs, spirit grasses are born, and under the continent, mineral deposits are born.

All these arise in the operation of the small thousand worlds, and they can give birth to life and even produce matter by themselves, which shows that the 'small thousand worlds' have completely broken away from the scope of the cave heaven.

After Dongtian was promoted to the Small Thousand World, the space that could be accommodated was even larger, and the various vitality contained in it was also more numerous. Not to mention that after Dongtian was promoted to the Little Thousand World, the laws of the world were even more complex and orderly.

With the promotion of Dongtian to the Little Thousand World, after enveloping the ancestral root of the Divine Tree in its entirety, the demonic sound that was still roaring has become inaudible. The Xiaoqian World continued to change, and more and more of the origin of the Divine Tree was digested by the Xiaoqian World, and that demonic sound naturally disappeared.

Because of the barrier of the small world itself, the magic sound could not pass through the barrier of the world barrier, so it could not be transmitted to the interior of the world. Without the interference of the magic sound, the Northern Yin Sulphur on the Six Paths of Roulette was immediately freed from the predicament of the internal tribulation. The internal tribulation that was originally counterattacked due to the interference of the magic sound was immediately suppressed by him and gradually eliminated.

Without the interference of the internal tribulation, the external calamity cannot enter the interior, and the transfer of the robbery in the Northern Yin Capital has become very easy. Ling Yun controlled the small thousand worlds here, allowing the power of the six roulette wheels to run smoothly and projecting the power from the small thousand worlds.

Because of the shield of the small world, after the six roulette wheels are running, they will not be disturbed by the power of the great universe, and the matter of the Northern Yin and the Divine Capital will become logical.

I saw that above the six roulettes, the whole person of Beiyin Yudu began to change, and it began to produce more and more light from the inside out, and the light emitted out, enveloping his whole person.

In the end, the whole person of Beiyin Xudu turned into a bright and flickering bright light, and the light was extremely pure, as if it surpassed the nature of all the light in the world, as if the whole heart light was pure from his heart.

"Six Paths Operate, the Gate of Reincarnation - Open!" A congenital divine voice sounded from the underworld, and two divine spells were announced, completely activating the six roulette.

The boundless power of reincarnation broke through the barrier of the ancestral root of the Divine Tree and swept through the entire small world. In an instant, Ling Yun felt that within his small thousand worlds, except for the Ancestral Roots of the Divine Tree that had not yet been completely devoured, and the World Tree, all the lives were dying in an instant. The whole world has become a barren and dead world, and some of the vitality that has been accumulated has disappeared completely.

Feeling the raging power of reincarnation, Ling Yun instantly panicked for a while, if his entire Xiaoqian world fell into a dead silence, his world would probably suffer a heavy blow, this was a major event for him to shake the foundation of his cultivation, so he couldn't help but panic.
