Generally speaking, no matter what kind of secret realm it is, it is dominated by the strongest life that is bred by this secret realm itself.

Even if the Master of the Secret Realm is killed and his bones are shattered, as long as this Secret Realm still exists, a new Master of the Secret Realm will naturally be born.

Most of the resurrected Secret Realm Masters will remain the same as the previous generation, and even their abilities are not much different.

This is because all the Secret Realm Masters are the strongest creatures bred by the Secret Realm itself, representing the rules unique to this Secret Realm, and the more powerful the Secret Realm Master, the longer it will take to resurrect.

Theoretically speaking, as long as the world in the secret realm is not interfered with by human forces, nothing will change for a thousand or ten thousand years.

In the secret realm, there is almost no limit on the lifespan of the master of the secret realm, but except for a very few masters of special bloodlines, the strength of most of the master of the secret realm will not increase.

In other words, a second-level secret realm that has been closed for 10,000 years, and if the second-level secret realm master does not have some special bloodline, it is difficult to be promoted to the next level.

The only one who can continue to grow and become stronger is the powerful Ancient Bloodline Secret Realm Master like the Heavenly Cicada, Xiangliu, and the Four Saints.

Among them, the four holy beasts Qinglong, White Tiger, Vermilion Bird, and Xuanwu who came out of the secret realm have become the representatives of the twelve earth immortals, and the great beings like gods in the eyes of mortals in the seas and mountains.

For a long time, almost all of the secret realm and the seas and mountains were river water, and even the secret realm race once allied with some forces in the human race to participate in the stage of the seas and mountains.

However, this qiē has been completely changed with the change of the laws of heaven and earth.

No one knows when the secret realm began to be isolated from the seas and mountains, and the secret realm races can no longer enter the world of the seas and mountains at will, but the side of the seas and mountains can take the initiative to enter the secret realm (those who enter cannot exceed the limit of the secret realm).

This kind of extremely unequal rules has brought a huge catastrophe to the secret realm. Since the Secret Realm race could not go to the seas and mountains, the monks of the seas and mountains could enter through the entrance of the secret realm, which caused unilateral plunder and invasion.

It didn't take long for the relationship between the secret realm race and humans to deteriorate completely, and it became an endless relationship.

The master of the secret realm almost instinctively inscribed such a law - human beings must die, and every foreign invader must die!

Therefore, the master of the secret realm is the enemy of mankind by nature, and almost all the secret realms have the principle that the foreign invaders have not missed the principle, which is a memory that has been engraved in the blood, like an instinctive rule.

However, just as the same rice raises hundreds of people, the secret realm is also like this, among the thousands of secret realms, there will occasionally be a strange secret realm.

That is the secret realm that Mei Xue encountered at this moment, where the human supernatural powers were the masters of the secret realm.

Theoretically, if human beings can rely on their own strength to defeat the master of the secret realm, and obtain the approval of this secret realm, they can indeed become the master of the secret realm.

The definition of the Master of the Secret Realm is the strongest creature that has been bred in the Secret Realm, which means that if a human successfully challenges the Master of the Secret Realm with his own strength and is recognized by the Secret Realm, he can become the new Master of the Secret Realm.

However, such examples are simply rarer than giant pandas.

First of all, you have to be stronger than the Master of the Mystery, and you can't use team tactics, but completely rely on your own strength to defeat the Master of the Mystery.

There is a paradox hidden in this, that is, the secret realm never allows the entry of immortal warlocks or supernatural beings who are more powerful than the secret realm itself.

This is also the reason why Mei Xue had to put a sealing immortal talisman on himself in order to enter the low-level secret realm, if he insisted on entering this low-level secret realm with the immortal ring of the seas and mountains, the result would definitely be that the secret realm completely collapsed, and Mei Xue could get a free ticket to travel permanently in the void turbulence.

In other words, you must defeat the Master of the Secret Realm in one-on-one with a lower strength than the Master of the Secret Realm, in order to be eligible for the recognition of the Secret Realm itself.

Secondly - you need to be approved by the Secret Realm, and after defeating the Master of the Secret Realm one-on-one, the Secret Realm will send a special message to test whether you really want to become the Master of the Secret Realm.

This process cannot be false, only those who sincerely want to become the master of the secret realm, and who are themselves suitable for this secret realm, will truly gain the recognition of the secret realm.

However, even if these two points are satisfied, there is the third most difficult point, which is almost impossible for the seas and mountains to accomplish now—you have to get the approval of the other masters of the secret realm.

The secret realm of the seas and mountains has never existed independently, and there are void passages like spider webs in the secret realm and the secret realm, which are occasionally used by powerful secret realm masters to shuttle, which is also the basis of the secret realm race civilization.

Humans have become the masters of the secret realm, which is actually nothing at the stage when the secret realm race and the seas and mountains can still communicate, and even the humans who are willing to become the masters of the secret realm are quite popular.

Because human beings who become the master of the secret realm are born with the spirit of wisdom, and the potential after becoming the master of the secret realm is very huge, and the number of masters of the secret realm is too small, it is rare to find some companions who can talk and communicate, so it was a very good choice to let humans become the master of the secret realm in ancient times.

However, this state of affairs was limited to before the change of the rules of heaven and earth in the seas and mountains.

After the secret race was isolated by the seas and mountains, almost all the human beings who tried to become the master of the secret realm became the enemies of the secret race, and they were the real public enemies of the people.

And for the human side, once you become the master of the secret realm, it means that you will be isolated from the seas and mountains forever, and you will become an outlier from the seas and mountains.

Therefore, after the primeval covenant was broken, the human beings who became the masters of the secret realm were almost extinct, and were replaced by the "Boundary Tower" system.

Those boundary towers standing tall in the secret realm are the views of human beings on the secret realm race in the era of immortal civilization, representing the arrogance of the immortal warlocks.

The secret realm race is low, ugly, and is a prop used to obtain materials and treasures, which is the view of the immortal warlocks on the race living in the secret realm.

Especially those low-level secret realms, almost all of them have become the breeding farms and resource collection places of the immortal warlocks, and every year, there are countless resources produced by the secret realms that continue to enter the seas and mountains, and it can be said that more than half of the cultivation resources of the immortal civilization in the seas and mountains are produced from the secret realms.

In this situation, who would want to become the master of any secret realm, especially the master of a low-level secret realm?

However, the handwriting on the crown, as well as the special rule that if you kill monsters in this secret realm, you will directly drop gems, gold, and even the crown, all tell Mei Xue - this is a special secret realm dominated by the great supernatural powers of mankind.

There are absolutely no such strange rules in a normal secret realm, and there will be no such mischievous slogans and declarations.

"Congratulations, this secret realm has been penetrated by you, but this is only the beginning, the real horror is still to come, boy, let's challenge the limit......" After reading these hints on the crown again, Mei Xue smashed this gorgeous gem crown into pieces with a snap of her fingers.

For immortal warlocks, the gold treasures that are common in the mortal world are meaningless, only immortal stones, and all kinds of genius earth treasures containing spiritual energy are universal goods.

It is no joke that a fairy flower can buy dozens of mortal realms, but the common sense of the world of immortal warlocks.

"yes, it's a pity, it's the spoils of war." Zhu Huo, who was sheltered by Mei Xue, regained her vitality, and she looked curiously at the powder of the gorgeous jewel crown, with a wasted expression on her face.

"It's not that simple, except for the herbs, there is a strange aura on these items." Mei Xue took out the gems and coins that she had dropped from killing the monsters, and smashed them one by one, leaving only green and yellow herbs.

Among all the drops, only these two medicinal materials did not contain other breaths, and they were truly elixirs cultivated by the Secret Heaven and Earth Vitality.

There are many differences between the rules of the secret realm and the seas and mountains, and most of the corpses of the monsters in the secret realm will quickly disappear after they die, leaving only part of the essence.

These essences and some special resources in the secret realm are the things that can be brought back to the seas and mountains, and the rest of the qiē can't be brought out, this is the rule that exists before the secret realm and the seas and mountains are separated, and it is the essential gap in the world.

There is still no real accurate answer to the origin of the secret realm, but there is no doubt that the secret realm is closely related to the seas and mountains, and the theory that the secret realm is the fragments of the seas and mountains is also the most affirmed.

However, no matter how close it is to the world of the seas and mountains, there are still many rules in the secret realm that the seas and mountains cannot understand, which is probably one of the biggest reasons why the secret realm race is difficult to be recognized by the seas and mountains.

"Gah! Ga! Ga! A crimson road sign appeared in front of Mei Xue and Zhu Huo, as if to show the two of them the way.

Every few seconds, the sign flashed and flashed, as if urging the only two guests in this secret realm to hurry forward.

"Big brother, do you really want to go in?" It's just that Mei Xue came to this strange secret realm, and Zhu Huo, who didn't know that this secret realm would be so perverted, pulled the corner of Mei Xue's clothes, obviously not wanting to go in again.

"Well, I have to go." Mei Xue nodded.

Whether this is the secret realm ruled by the human secret realm or the secret realm ruled by the innate secret realm, it is the same for him.

Because, what he had to tread was the entire sea and mountains, how could he stop in a mere fourth-level secret realm.

Even if most of the power in her body is sealed by herself, and she can only use the purest amount of flesh to fight, Mei Xue still has to conquer this secret realm and hold every aspect of this secret realm in the palm of her hand.

Whether it's a ghostly monster or a demon or a monster, is it comparable to the indescribable terror of the Upper Nine Shadows, and comparable to the Demon Eye Clan Lord who dominates the world of the Ten Directions?

"You don't have to go, there shouldn't be anything good here." Mei Xue patted Zhu Huo's head, in fact, with Zhu Huo's strength, there is absolutely no need to be afraid of this fourth-level secret realm, except for the secret realm master who has not come forward, there should be no monster that can really threaten this mysterious demon girl from the southern sea.

It's just that the monsters in this secret realm don't seem to have a good relationship with Zhu Huo, and those ugly and disgusting things are really uncomfortable to look at, and it's not strange that Zhu Huo is not used to it.

Of course, if Koyanagi is there...... Mei Xue imagined a little in her mind, probably these monsters had all melted into the sea of blood before they even touched Xiao Yanagi's side.

"That'...... That's not good, I'm the Zhu Huo of the Four Heavenly Kings, it doesn't matter, I'll get back to my state soon. Zhu Huo puffed up his small chest, obviously very dissatisfied with what he had just said.

There's no way, she has been pampered since she was a child, except for the time when she peeked at Daxia Longji, she really hasn't seen such a disgusting and bloody scene, especially the kind of monster that is half human and half scorpion, and her whole body is constantly bleeding, which directly made her almost vomit.

Really, what's going on in this secret realm, who is so evil!

"Then, learn to accept it, don't be afraid, you are far stronger than them." After experiencing the battlefield trials of the Dragon Jade War, Mei Xue has long surpassed the stage where she is not suitable for seeing blood.

Although it can't reach the red wolf's Cheng Dù, who kills rivers of blood and doesn't change his face, a few twisted monsters are not worth his real frowning.

"Okay, I'll let these monsters know how the Suzaku Fire burns." Vermilion snapped her fingers, and a wisp of crimson flame burned from her fingertips, illuminating the surrounding mist.

"What you're left with is the power of fire?" Mei Xue looked at the flames on Zhu Huo's fingertips, due to the restrictions of the rules of the secret realm, the power beyond the limit of the entire secret realm would be automatically sealed by the sealing immortal rune, so Mei Xue chose to leave the purest amount of flesh.

And Zhu Huo is obviously the opposite, what she seals is the power of her own body, and what she retains is the power of flames.

This also explains why she was so wolf just now, obviously her flame power is not suitable for facing hordes of monsters at the same time, these monsters will not give her time to calmly use the power of fire.

If you want to describe it, Mei Xue's strength at this moment is closer to the supernatural side, with the extraordinary power of steel body and infinite anger, while Zhu Huo is closer to the immortal side, with the power of manipulation of heaven and earth as the combat method.

Under the restrictions of the rules of the secret realm, the strength of the two is limited to the master of the secret realm, but the combat power is not limited to the simple combat power, the use of immortal arts, supernatural powers, strategy, psychology, and even the number of treasures carried with them can determine the final outcome of a battle.

Otherwise, in front of the master of the secret realm who occupies the heavens, the place, and the people at the same time, the human race has no chance of winning at all, and it is simply a fool's dream to defeat the master of the secret realm.

However, even if they were completely prepared, most of the team that encountered the master of the secret realm still died without a single one left, and not everyone had the same strength as Mei Xue and Zhu Huo.

Except for a very small number of teams, the so-called secret realm exploration will basically stay away from the core area where the secret realm master is located, after all, the advantage of the secret realm master in the secret realm is too great.

"Hey, this is the Suzaku Fire, burn them!" Zhu Huo didn't care and said his hole cards in front of Mei Xue.

The legend of the southern seas, the only surviving southern holy beast among the four holy beasts, the Vermilion Bird, is a living historical witness of the seas and mountains, and the only demon holy beast among the four holy beasts that has not fallen.

Although she had more or less guessed that Zhu Huo had something to do with this southern holy beast, Mei Xue was still taken aback by watching Zhu Huo sacrifice this Vermilion Bird Fire.

This is the power of the true Holy Beast Inheritance, and it may even be more glorious than this generation of the Blue Dragon King, Canghai Jiao.

After all, the Eastern Holy Beast Qinglong has long since fallen, and only the inheritance of the Green Dragon King and the Qinglong Immortal Gate are still circulating, while the Southern Holy Beast Vermilion Bird is still alive, and being able to have this Vermilion Bird Fire is enough to prove that Vermilion Fire has been favored by Vermilion Bird, otherwise it will definitely not be able to have this flame that represents the power of Vermilion Bird.

Even if the flame before the vermilion fire was only a small flame, Mei Xue could feel that this flame contained a power that burned heaven and earth and purified a qiē, which was the characteristic of the legendary Suzaku fire - Nanming Lihuo.

"Ding! Bite! Bite! The crimson cursor flashed and flashed, as if to remind Mei Xue and Zhu Huo that it was time to go.

The fourth level of the secret realm, which means that this secret realm has four layers, according to the rules of the secret realm, the master of the secret realm is generally in the deepest, but also the most monsters, the most terrifying fourth layer.

The number of layers in the secret realm is not a simple relationship between the top and bottom, there is a pyramid system like a green ruin, a multi-layer roulette system that is folded together, and even a Babel Tower system that is upside down and leads from the lowest floor to the highest level.

The next level of this ghost village secret realm is a typical four special areas divided by regions, because what Mei Xue saw at the end of the cursor was a huge castle, which was completely different from the village in the first area.

"Gah! Ga! Ga! The gate of the ancient castle slowly opened in front of Mei Xue and Zhu Huo, and then a large number of bats flew out of it, covering the sky and countless days.

"Burn you!" At this time, the flame power of Vermilion Fire finally exploded, and dozens of crimson firebirds flew out from her fingertips, and these firebirds whose whole body was made of Vermilion Bird Fire rushed directly into this group of bats, and then one by one the vampire bats burned and fell from the air like dumplings.

Most of the vampire bats were burned to ashes by the Vermilion Bird Fire before they could hit the ground, and only a very small number of fish that slipped through the net flew to the top of Mei Xue and Zhu Huo's heads, and then were blasted into pieces by Mei Xue with a single punch effortlessly.

In keeping with the tradition of this special secret place, this large group of vampire bats dropped a lot of strange things, including many crystal clear red heart-shaped crystals, bottles of clear liquid, wooden shelves woven into crosses, and a chubby, round, golden-yellow food with a nice aroma.

"What is this?" Zhu Huo picked one up curiously, these items were directly suspended on the ground, so they were not contaminated with dirty things, among them, this chubby, round golden food, made Zhu Huo curious.

"Wait, this ......" Mei Xue didn't know why she had a very strange feeling when she saw this chubby, round food, and always felt that something was wrong.

Unfortunately, his reminder was too late, and the curious Zhu Huo had already bitten into the chubby, round and strange food, and then happily ate it. opened, and then a large field of bats flew out of it, overwhelming the sky and counting.
