It was a dim, dead place, and the whole space was filled with the smell of decay, death, and twilight.

After Hua Yu rushed into the whirlpool, he came here in a whirlwind, standing on top of a mound and looking around left and right, but he didn't see the gray-robed man and Xue Qingyue.

"The laws of heaven and earth are very different from the outside world, this is not the Cave Heaven Secret Realm, this is a Void Realm."

After feeling the breath in the space, Hua Yu made a judgment.

The Cave Heaven Secret Realm and the Void Realm are not the same. Although this kind of secret space is also relatively independent and has its own characteristics, the laws of heaven and earth in the space are the same as those of the great heaven and earth, and the secret realm of the cave is also a part of heaven and earth in the final analysis.

The Void Realm refers to the realm independent of the Divine Continent Heaven and Earth, and according to the strength of the origin and the perfection and stability of the law, these Void Realms can be divided into different levels, such as the Bubble Realm, the Lifeless Realm, the Small Heaven and Earth, and the Qiankun World.

Among them, the realm of bubbles is only a small space, and the realm of bubbles is very unstable, just like bubbles, so it is called the realm of bubbles.

There is no life, there is a certain space, time and space are relatively stable, but life cannot be born, nor can it be inhabited by living beings, and the space in the storage magic weapon is a typical lifeless world, but the space relies on the magic weapon.

Small heaven and earth, time and space are stable, and the laws of the Great Dao are stable and orderly, but the laws of heaven and earth are unbalanced, and the laws of heaven and earth are often biased towards a single attribute, such as water, fire, thunder, and so on. The small world can be inhabited by living beings, and there is also the basis for the birth of life, but most of them are some vitality creatures, such as fire spirits, thunder spirit beasts, and so on.

In the Qiankun world, the laws of the Great Dao are balanced and orderly, a variety of living beings can be born, and the origin of the world is strong, such a realm can be called the world. Shenzhou Heaven and Earth belong to the Qiankun world. Of course, the Qiankun world also has different levels according to the strength of the world's origin.

In the Universal Void, there are many large and small realms, and the Divine Continent World is one of them. Above the Divine Continent World, there are countless bubble realms and lifeless realms, and even some small worlds.

The formation of these bubble realms, inanimate realms, and small worlds has a variety of origins, such as the friction between the rhythm of the world and the surrounding time and space, the formation of cultivators, or the attraction of the Divine Continent World to the surrounding large and small realms, or the movement of the Universal Void, etc.

The space in front of him is obviously a Void Realm, and according to the division of the Void Realm, it should be a small world, but this world seems to be about to collapse.

The whole small world is full of decay and imminent destruction, giving people the illusion that they can feel the helplessness and sadness of this small world.

The world in front of me is a gray tone, gray hills, gray rivers, gray skeletons, gray fog, gray sky, without feeling a trace of vitality, giving people a creepy and chilling feeling.

"There is such a strange little world, no wonder there is so much dead air in the 'death swamp' of the outside world, it turns out that it is affected by this small world. ”

Hua Yu hurriedly released the Mingyu Palace hanging above his head, and the Mingyu Palace hung a ray of light to isolate the surrounding dead qi, which even cultivators could not inhale too much.

"You can't stay in this place for long, no matter what, let's find Senior Sister Xue first. Hua Yu discerned the direction and rushed towards the center of this small world.

After running all the way, Hua Yu came to a horizontal mountain, a thick gray mist shrouded the peaks, and the dead and decaying aura here was much thicker than in other places.

Due to the gray fog, the divine sense could only probe a short distance, so Hua Yu did not dare to continue to fly in the sky, so he had to honestly use footwork to climb up. It's just that it didn't take long for trouble to run into trouble.

"Well, what the hell is this? ”

Some ghost-like things in the gray mist kept attacking, and their bodies seemed to be composed of gray mist, and they looked like strange faces, all with large mouths and fangs. As soon as he found Hua Yu, he rushed desperately.

"It seems to be a creature, but it doesn't have the slightest life, could it be that this is the legendary undead and ghost clan?"

Hua Yu pointed like a sword, sending out wisps of sharp sword qi to kill all the ghosts that approached, these things looked very vicious, but for Hua Yu, it was only more troublesome, and there was no big threat. With a stomach full of questions, Hua Yu rushed towards the top of the mountain.

On the way to climb the mountain, there are constantly ghosts attacking, which makes the speed of climbing the mountain very slow, Hua Yu tried to use illusion to cover his body, and at the same time restrain his own breath, but it doesn't seem to work, and I don't know what kind of sense these ghosts rely on, no matter what, they will be sensed. Under such circumstances, after wasting a lot of strength, Hua Yu climbed to the top of the mountain.

"Is this...?" After reaching the top of the mountain, Hua Yu looked at the prospect with his mouth wide open and surprised.

There are three other peaks that are the same as the peaks that Hua Yu stands, and when the four peaks are taken together, they look like a huge coffin, and a thick gray mist is shrouded in it, like the lid of the coffin.

All the dead energy in this small world seems to originate from this place, which seems to be the source of death and decay, the final destination of all living beings, as if even this world can be buried.

"Is this a natural formation of this heaven and earth, or is it man-made? If it is man-made, then who is this person, and what is the purpose?" Hua Yu asked in a muttered voice.

"I thought that this piece of heaven and earth was full of dead qi and was the reason for the laws of heaven and earth itself, but now it may also be ......." Hua Yu didn't dare to think about it, if it was really as he guessed, it would be too terrifying.

Can anyone really change and reverse the laws of the entire world by himself, and take a piece of heaven and earth as the object of study? Although this is only a small world, it is also very amazing.

The magical methods of the cultivator revealed the tip of the iceberg, giving Hua Yu a new understanding of the title of cultivator.

Eliminating the distractions in his heart, Hua Yu walked towards the coffin-shaped valley composed of mountain peaks on all sides, the valley is not flat, all kinds of large and small peaks are lined up, and the outer gate is the same, and the coffin also has a small world of its own.

"It's getting more and more dangerous, but with intuition, if you want to find Senior Sister Xue and a way out, you have to move forward. ”

The dead air in the valley in the coffin has become more intense, and the ghosts in the gray mist have become more difficult, often taking several times to solve one, and from time to time they also encounter some monsters composed of white bones, this kind of white bone monsters are even more difficult to deal with, in order to avoid unnecessary fights, Hua Yu often avoids it if he can. In this way, Hua Yu cautiously hurried towards the center of the valley.

"Well, what is it?"

When passing through a place, a strange movement attracted Hua Yu, and after feeling it carefully, Hua Yu rushed to the place where the abnormal movement occurred with curiosity.

A wave of Dao rhyme came from a small hill, and as Hua Yu got closer, the feeling became stronger and stronger.

Feeling the fluctuation of this Dao rhyme, Hua Yu couldn't help but look happy, and sent out an incomparably sharp Gengjin sword qi and slashed straight down the hill.

After a burst of dust, a black ore was revealed, and a wave of rhyme emanated from this ore, and there were some mysterious textures distributed on the surface of the ore.

"It's... Dao Yun is rare, and it is also the top Dao Yun treasure. Hua Yu looked at the ore and exclaimed happily.

No wonder Hua Yu is so out of shape, this level of treasure is a rare treasure even among top sects like Taixuanzong, and he has only heard of it on weekdays, but he has never really seen it.

It is no wonder that cultivators are so eager for all kinds of cave heaven secret realms, former cave mansions, and some small worlds, and this piece of ore alone is worth the trip.
