In the battlefield of the heavens, there exists a breathtaking fantasy land.

This is a vast ocean, but it is not the deep blue in the traditional sense. Instead, it is suspended high in the sky, like a glass sky pulled by magic.

This sea of ​​sky is colorful and magnificent, like a flowing painting.

The sea is sparkling, and every ray of light seems to be carefully woven, forming countless gorgeous colors.

The sunlight shines through the sparse clouds and onto the sea, creating layers of golden ripples, like bright stars scattered on the earth.

In this vast sea of ​​sky, there are marine creatures of various shapes and forms swimming around.

Some are like huge crystal palaces, crystal clear and emitting charming light; others are like colorful clouds, light and flowing, dancing in the wind.

They play on the sea surface or dive deep into the sea to explore the unknown mysteries.

At the edge of the sea of ​​sky are rolling mountains of clouds.

These clouds and mountains have different shapes, some look like coiled dragons, and some look like phoenixes spreading their wings.

They quietly guard this mysterious sea area, adding a bit of solemnity and mystery to this sea of ​​​​sky.

In this magical sea of ​​sky, the air is filled with a faint scent of sea water mixed with a hint of fresh floral fragrance.

The breeze blew, bringing with it the sound of waves, as if it were the breathing of the sea in the sky, soft and long.

Here, time seems to have lost its meaning. People can only indulge in this beautiful ocean and forget the troubles and hustle and bustle of the world.

At this moment, Ye Ning was riding on a cloud, looking down at this magnificent sight from the higher sky.

Looking at this fantastic scene, Ye Ning said with some emotion: "It is said that many landscapes in this world are the work of nature, but even those special secret realms on the blue planet pale in comparison with this sea of ​​sky."

Standing next to Ye Ning was a woman who was dressed in black. She was also feeling refreshed as she watched the magical scene below. She was Chu Mo, whom she hadn't seen for many days.

Hearing Ye Ning's words, she raised her head and looked at Ye Ning, smiling and said: "There are many wonderful places in the universe, and the battlefield of the universe is the most wonderful. Although the sea of ​​sky is indeed a rare sight among them, there are still some places that are more wonderful than the sea of ​​sky."

Hearing this, Ye Ning raised her brows slightly, her curiosity instantly aroused: "Sister Mo, tell me in detail!"

Chu Mo, who knew Ye Ning's character, smiled slightly. She had guessed that Ye Ning would ask this question, so there was nothing she couldn't say at this moment: "If I really go into details, I can't finish talking about the wonders in this battlefield of the heavens, but I can give you a general idea."

Having said that, Chu Mo paused, then glanced at the sea of ​​sky below the clouds, and then stepped forward lightly. Just when Ye Ning was surprised at why Chu Mo suddenly lost his mind, Chu Mo leaned down and made a sitting motion, and then sat directly on the edge of the cloud.

Seeing Chu Mo's action, Ye Ning was a little speechless and said, "Sister Mo, you are too scary. Aren't you afraid that the edge of the cloud under my feet is not solid enough? If you don't sit firmly, you will fall down directly."

Chu Mo didn't look back, but just waved his hand gently: "If you fall, you fall. This place is not too high from the ground. The worst that can happen is that you will fall directly into the sea. Don't underestimate me, your sister. Although I am a little worse than you, a little pervert, I have already successfully reached the peak of the Heavenly Phase Realm."

Ye Ning was not surprised about this. In fact, he discovered when he saw Chu Mo again that Chu Mo had obviously had some adventures during this period. Although his strength improvement was not as good as his, it was not slow at all.

At this moment, Chu Mo's fingers gently brushed the hair beside her ears, and she suddenly said, "By the way, my Wedding Dress Secret is almost full recently. I'll give it to you again after a while. It just so happens that I can also take advantage of the feedback power to rush to the realm of the Venerable."

Ye Ning's face lit up when she heard this: "Sister Mo, your progress is not slow. You are about to make a breakthrough."

Hearing Ye Ning's words, Chu Mo frowned and turned back, then raised his head slightly, and then stared at Ye Ning.

Ye Ning felt a little flustered when Chu Mo stared at him. He scratched his head and said awkwardly: "No, did I say something wrong?"

"Humph!"

Chu Mo snorted coldly and turned his head away quickly. He was silent for a while before saying, "When I entered the Dharma Realm, you were still a young boy who didn't even know the method of surrendering. But when I just had a chance to break through to the Venerable Realm, you have already stabilized in the Venerable Realm and even your mental strength has broken through the Venerable Realm. You call this rapid progress?"

"Hey, Sister Mo, you can't compare with me. My situation is different."

"What's the difference? Why can't I compare with you?"

Ye Ning: “…”

Hearing Chu Mo's tone, Ye Ning was speechless for a moment. He opened his mouth and found that it seemed inappropriate to say anything more.

It is said that it is the most difficult to accept the favor of a beautiful woman. Even after going through ninety-nine calamities of all living beings, Ye Ning still felt that he was not very good at it.

After all, in those ninety-nine worlds, he always knew that it was fake.

No matter how real that world is, even if the ninety-nine worlds in the [Map of Mountains and Rivers and the State] are all well and good at it, it is still fake.

It would be better for him to say less at this time.

Feeling that Ye Ning behind him didn't say anything else, Chu Mo, who was sitting on the edge of the cloud, had a flash of disappointment in his eyes, but it quickly disappeared.

I saw her placing her hands slightly on both sides of the clouds, and her body leaning back slightly, revealing her beautiful figure above the sea of ​​​​sky.

But there was no one around here, so no one could appreciate it.

Ye Ning naturally couldn't see it either.

Although this kid's mental power has spread beyond the realm at this moment, he set up an isolation circle within a one-meter radius around Chu Mo's body without any intention of offending him.

Chu Mo looked down.

Hmm, I can't see the toes: "Okay, let's stop talking nonsense, let me tell you about the battlefield of the heavens first."

"Appreciate further details."

"First of all, it is..." As Chu Mo continued to tell his story, Ye Ning finally had a general understanding of the battlefield of the heavens.

Although it is called a battlefield, in fact there is not much real fighting.

Although this battlefield of the heavens has gathered countless powerful people from all the heavens and worlds, this place is vast and even a powerful person like a god cannot calculate the actual size of this place.

Not to mention that there is not just one layer of space here, and this is not even the entire battlefield of the heavens.

According to information obtained from other worlds by some powerful people who are good at communicating with others, the battlefield of the heavens was once called the battlefield of three thousand worlds. It is not clear whether this three thousand is an imaginary number or a real number, but there were at least three thousand spaces.

Of course, that was in the past, countless years ago.

It is said that a war that truly affected all the worlds once took place in this battlefield of three thousand worlds. That battle was earth-shattering, and the entire battlefield of three thousand worlds was completely transformed into a huge meat grinder.

Countless strong men fought, countless strong men fell, and most of the original three thousand world battlefields were shattered.

Some fragments of the battlefields of the Three Thousand Worlds gathered together and then merged with the special environment brought about by the fall of some strong men, forming some special regions.

Some fragments of the battlefield of the Three Thousand Worlds floated into the void, and were then sucked into different worlds. They then merged into those worlds and turned into special secret realms.

No one knew how many years the war lasted, but when the battle was over, all the heavens and worlds were shattered, and only more than a hundred spaces were left on the battlefield of the Three Thousand Worlds. Some of them had become forbidden areas like purgatory on earth because of the deaths of truly powerful people.

The so-called forbidden area is a place where even those at the divine realm would be at risk of falling, and entering below the divine realm is an even more terrifying zone where there is almost no chance of survival.

There are currently a total of eighteen levels of forbidden areas like this in the entire battlefield.

Of course, now this sea of ​​sky is not a forbidden area, it belongs to the sky domain, one of the thirty-six heavenly domains.

The Thirty-Six Heavenly Realm is the safest of the thirty-six spaces in the entire battlefield of the heavens. Generally speaking, as long as you don't commit suicide here, even those in the Three Phases Realm can get some opportunities here. If you are lucky, the opportunities you get are actually not bad. It's just that precisely because it is relatively safe, it has been visited the most throughout history. Most of the opportunities that are easy to get have already been taken away, so many opportunities can only be obtained by luck.

In addition to the thirty-six levels of Tiangang Realm and the eighteen levels of forbidden realm, the remaining space in the battlefield of the heavens is the seventy-two levels of Disha Realm.

Although the seventy-two-layer Earthly Demon Realm is much less dangerous than the forbidden area, it is much more dangerous than the thirty-six-layer Heavenly Realm. Generally, only strong people at least in the Venerable Realm can go there.

In fact, judging from the opportunities alone, the Disha Realm may not have more opportunities than the Tiangang Realm, but because the danger is higher, it is explored less, and it is easier to get opportunities.

Although Ye Ning was quite confident in his own abilities, there was no need to make himself uncomfortable right from the start.

In this battlefield of the heavens, many rules are actually different from those in the Blue Star world, and one must adapt to them first, so he was not in a hurry to go to the Disha Realm to experience the danger.

It just so happened that Chu Mo received news that a limited opportunity was about to open up in this sky area, so he came over to join in the fun.

This place was discovered by a senior from the Xian Qin Empire several decades ago. In this sea of ​​sky, a special passage appears every once in a while, and behind the passage there is a special palace.

After entering the palace and completing the challenge, you will get a special treasure. The treasure may be various things, and everything depends on the result of the challenge.

According to that senior, that special passage appears once every ten years, and in these few days it will be another ten-year period. For Ye Ning, it can be said that it is better to arrive at the right time than to arrive early.

This special passage seems to be somewhat similar to the temporary secret realm that Ye Ning had entered once. After Ye Ning expressed this doubt, Chu Mo told him that the temporary secret realm was completely incomparable to this place.

No matter what kind of temporary secret realm it is, it is derived from the broken fragments of the original Three Thousand Worlds battlefield, but the special passage here is not. This is a magical thing that existed before the war.

Speaking of it, this sky domain is actually a very magical place. Within this space, there is sky above and sky below. In this space, there is a line called the Earth Line. Of course, it is not a real line. To be precise, it is an invisible surface.

Once a person passes through this plane, up and down will instantly be reversed. To use a more modern explanation, the world is divided by the invisible plane, and the direction of gravity on both sides is the invisible plane.

What is even more amazing is the sky on both sides. In this world, the higher you fly, the greater the gravity. Even if you use all your strength at the Venerable Realm, you can only fly to a height of several thousand meters before you can no longer withstand the gravity.

Those above the Saint Realm can withstand this gravity and continue to fly, but as long as they continue to fly upwards, it won't be long before they find themselves in another level of the sky, diving towards the ground. You must know that the directions of gravity in the two skies are completely opposite. Generally speaking, even if there is a shift, the change in gravity direction should be instantly noticeable.

Not to mention the strong ones in the Saint Realm, it is said that the strong ones in the God Realm who tried it didn’t know when the transformation occurred. All the strong ones who flew to a certain altitude said that they found themselves in the other half of the sky almost in a trance.

No one knows at what exact altitude the change occurred. There must be some secret hidden in it, but it has not been discovered so far.

And that certain height somewhere unknown is called the line of the sky.

Across the line of the sky is another sky, and across the line of the earth is also another sky.

This is the most magical place in the Sky Domain.

As for the sea of ​​sky below the two people, it is also quite special. It exists in two skies at the same time.

What’s even more amazing is that in this sea of ​​sky, it is the only place in the sky domain that can turn the invisible ground line into visible one.

Of course, it is not really visible, but its location can be determined.

As mentioned before, the farther the sky is from the ground, the greater the gravity. Conversely, the closer it is to the ground, the smaller the gravity. The moment it gets close to the ground, the gravity is almost zero.

And this sea of ​​sky that exists in the two skies forms an extremely special dividing line at the location of the line of earth because of this particularity.

In fact, that dividing line cannot be seen by the naked eye, but as long as you have a stronger mental power, you can feel that the waters on both sides of the invisible line are clearly separated. They are obviously tightly together but do not interfere with each other.

It's like a knife that is almost not thick cuts the sea into two halves and then carefully brings them together. Although the two halves of the sea are united, the water on both sides can never merge again.

The humans on Blue Planet call this magical phenomenon "A Line in the Sky".

Therefore, this sky sea has a nickname, the sea of ​​four seas. (End of this chapter)
