In many parts of Pangea, there is some space debris.

These fragments range from large to small, ranging from small to a dozen miles in radius, to as large as several states.

Originally, people confused the secret realm with the exotic, thinking that these were the spaces that Pangea had not been able to integrate with the continent when it was first formed.

Later, it was discovered that the secret realm was fundamentally different from the foreign land, the foreign land was a piece of heaven and earth completely different from the Pangea continent, and the secret realm was exactly the same as everything on the Pangea continent, and there was very little life in it.

Much of this space debris is in the interior of Pangea, hidden deep in the mountains or beneath the sea.

There are also many secret realms in the sky outside the firmament of Pangea, and inside is a complete or incomplete star.

The secret realms in the sky sometimes fall into the Pangea Continent, and eventually merge with the Pangea Continent.

The cultivators who first discovered these space debris thought that these debris were all stars suspended in the universe above Pangea, or some meteorites and other things.

Later, they found out that this was not the case, when the cultivator entered a certain range of these secret realms, they would find themselves in another dimension, and these spaces were not as barren as those on ordinary planets, but had their own set of ecosystems, and most importantly, the existence of spiritual energy.

Moreover, there are often many precious resources in these extraterritorial planets, such as spirit stones, minerals and even some precious medicinal materials.

Some cultivators speculate that these stars were separated from the Pangea Continent, and over time they formed an independent planet, and the heaven and earth on that side also formed an independent space.

Therefore, more and more cultivators use various methods such as magic circles to fly outside the firmament of Pangea Continent to search for these secret realms, and then establish a huge teleportation circle to facilitate the exploration of these secret realms.

As the cultivator's civilization became more and more prosperous, more and more secret realms of the outer lands were discovered.

In order to compete for the resources here, the cultivators will establish a huge base here and send a large number of cultivators.

Eventually, such a place will evolve into a brutal battlefield for cultivators.

Of course, there are also many powerful people who can directly open up a small space and form a new secret realm.

The secret of the secret realm has gradually been confirmed, that is, the space debris formed under the powerful force, and all the laws in the secret realm are completely consistent with the Pangu Continent.

Therefore, some great powers will open up secret realms as their own retreats for the needs of cultivation, and it is said that they will have such abilities in the Jindan period, and the size of the secret realms opened up above is different.

When the mighty person dies, these secret realms will automatically close, waiting to be discovered by future generations, or forever lost somewhere on the continent.

Whether it is a naturally formed secret realm or a secret realm that is thought to have formed, once discovered, it will be the object of competition for cultivators.

Old Man Bailu continued: "We have very few people in the Hanging Mountain, and this secret realm is too mysterious, so since we discovered it sixty years ago, we have been inviting some young Qi Refining Realm cultivators to enter the secret realm to explore together. ”

"The vision and pattern of the Hanging Mountain are really admirable!" Tengshan Zhenren said to the old man Bailu: "It is an example of the Jingzhou monks to open up the secret realm under their control!"

Bailu said: "Taoism has always advocated that the cultivation world should let a hundred flowers bloom and help each other. That's why so many great cultivators can appear in the land of the six states of our Dao Sect. Although I am not a disciple of Taoism, I also want to contribute to the prosperity of the Jingzhou cultivation community. All of this is just following the teachings of the Taoist Ancestor. ”

In the land of Taoism, the atmosphere in the cultivation world has always been like this, and few sects will be self-contained and closed-door.

This is all because the concept of Dao Ancestor is like this.

In the era when Dao Ancestor was growing up, the method of cultivation was firmly controlled by several great families, so the path of cultivation of cultivators was difficult.

After the Dao Ancestor, the cultivation sect arose, and even mortals could enter the sect for cultivation.

As a representative of the rise of sects and the spiritual leader of the world's sects, the Taoist sect will naturally not suppress the establishment of various sects, and actively advocate exchanges between various sects.

Under the influence of this atmosphere, the spiritual world of Middle-earth has always been thriving, and it is the center of cultivation on the mainland.

Old Man Bailu knew that there were few people in their Hanging Mountain, and most of his disciples had already formed a Dan, so he opened up this secret realm he had mastered and explored it with the young cultivators in Jingzhou.

Hanging Mountain has been doing this for nearly a hundred years, and as more and more people explore, many areas of this secret realm have been discovered, and it is likely that new areas will be opened.

"Look, this is the entrance to the Takakyu Cave. The old man stood up and came to the center of the field.

On top of the huge spirit stone under everyone's feet, a teleportation circle appeared.

After the magic circle was activated, the spirit stone flashed with a little light, and it was pitch black and deep, like endless night, and like a black cave with great martial arts appeared in front of everyone.

Ma Xie was a little dizzy, and he felt in a trance that above the spirit stone was the boundless universe, empty, silent, and pitch black.

Gradually, this piece of pitch darkness enveloped all the spirit stones, and a little starlight flickered, appearing in the darkness.

"This is the ...... of the universe" Ma Xie finally saw clearly, the scene on the spirit stone was the mysterious and huge outer land above the firmament, that is, the "universe" in the mouth of mortals.

Those little stars gradually became larger, and became stars one by one, floating towards everyone.

A red planet grew larger, slowly taking over the darkness.

When the planet took over the darkness, the spirit stone turned a dark red.

On top of these dark reds, there are also some undulating dark areas, which seem to be mountains, and what appear to be some rivers and lakes.

As the planet got closer and closer, everyone gradually saw the true face of the planet.

The red earth, the red mountains, the red ocean, the world is all red, and there is constantly a transpiration mist floating out of the earth, indicating that this is a very hot area.

"We have tried, and the temperature here is not unbearable for cultivators in the dantian stage, and only cultivators who have broken into the Dragon and Tiger Pass can enter. Ling Yan'er said, "This is an ancient battlefield, but the area we can explore is only a small part, so we don't know which two sects opened up the battlefield. ”

Between cultivators, there are very few battles between life and death, and even less between sects.

Only in ancient times, the exploration of foreign lands by cultivators was not perfect, and in order to pursue that pitiful resource, they often engaged in brutal sect wars.

Today's dragon slayers, with their understanding of foreign lands and the emergence of many cultivation methods, dragon slayers are more professional than previous cultivators, with a more detailed division of labor, more targeted exploration, and more efficient exploration of foreign lands.

They are professional treasure hunters and experts at exotic exploration and hunting.

The targets of the large sects have all moved from the secret realm to the foreign land, and such large-scale sect wars rarely happen.

However, for forces like Hanging Mountain or casual cultivators, the secret realm is still very attractive.

Gradually, a crimson mountain range appeared in front of everyone's eyes, and there was nothing on this mountain range, except for some huge craters, which Ma Xie guessed might have been left behind by the cultivators during the battle.

The mountains grew larger, and eventually a cave appeared in front of everyone.

"This is the Takikudo Cave. Our teleportation array can only reach this area, and for years, we have been exploring the Hanging Mountain. Ling Yan'er said: "Daoists who are willing to enter can come to my side to receive the teleportation token." ”

Seeing that there is a secret realm in front of him, who doesn't want to go in and try it? Even Ma Xie couldn't help but want to hurry in, wanting to see what was inside, what was the difference between this ancient battlefield and the current Pangu Continent.

The old man Bailu came to the top of the spirit stone and said to everyone: "Everyone, the old man has one more thing to ask for. ”

"This old man has hidden so much that he has finally told his true purpose. Yuan Wuji, who had been holding back for most of the day, finally couldn't help it, its head stretched out, looking at the strange scene below, and it was also fascinated.

Ma Xie pressed Yuan Wuji's head and listened carefully to the words of the old man Bailu.

It turned out that in this Takiku Cave, there was a mineral, which was something that the old man of Bailu had always needed, but he couldn't enter it to mine, so he needed to organize some powerful Qi Refining Realm cultivators to collect it inside.

As a report, Bailu would give these cultivators some cultivation resources, and the things they obtained in the secret realm could also be taken away or sold to others at a reasonable price, including the old man Bailu.

It's just that the secret realm here is only the edge of the battlefield, and it is a battlefield for Qi Refining Realm cultivators, and there is nothing that Bailu will look at.

The only thing he cared about was an ore produced in this Takiku Cave, the Light of the Mountain, which was a rare ore that was produced by only a few small countries in the southeast of the Pangea Continent.

The biggest effect of this ore is that it can be extracted from a substance called "Baiyan Jade", which is the medicine of many medicines, and Bailu needs a large amount of Baiyan Jade to refine a pill that can prolong life.

Ma Xie was very curious about the secret realm, and he regarded this exploration of the secret realm as a kind of practice before becoming a dragon slayer.

He walked up to Ling Yan'er and got a teleportation order, Ling Yan'er glared at Ma Xie and said, "Your carving insect skills can't hide from me." ”

But with that, she quickly turned around.

When Ma Xie passed by the old man Bailu, Bailu glanced at Ma Xie and said, "Evil Horse Daoist, the old man is looking forward to your performance. ”

When he said the word "you" again, Bai Lu specially accentuated his tone, it turned out that he already knew about the existence of Yuan Wuji, but he didn't break it.

Ma Xie nodded in gratitude, and then rushed into the spirit stone below.
