As mentioned earlier, the legendary inner world may not be in the center of the earth, but a three-dimensional world from another dimensional space.

It is precisely because it is a space world of another dimension that there are ancient creatures and plants that have long since disappeared on the earth.

Since it is a space world of another dimension, there is naturally not only one underground world, of course, there are countless underground worlds, and the earth in a broad sense is only the intersection of these dimensional spaces, providing a stronghold for people in these other dimensional space worlds to recruit enlightened people.

The earth has intersected with countless spatial dimensions of the underground world, but these underground worlds will not exist on the earth at the same time, because the earth can only intersect with a space of different dimensions from the earth.

Because only this dimensional space that originally intersected with the earth can share everything on the earth, and the later different dimensional spaces will not be accepted by the earth, and will be rejected by the earth.

In this later dimensional space, if you want to intersect with the earth and share everything on the earth, you have to exclude the dimensional space that intersects with the earth.

The dimensional space is a dead thing, and cannot directly participate in the process of acceptance and rejection, so only the indigenous people in these dimensional spaces can participate in these processes...... That is, the people of the underworld!

The way for these people from the underground world to compete for the intersection with the earth in their respective dimensional spaces is to start a war!

By starting a war, they fight with people from different underground worlds, seize the territory of the dimensional space represented by the rest of the underground world, kill the people of the other underground world, and seize the dimensional space occupied by the other underground world, this is the only way for them to compete for the earth.

To put it simply, it is the various underground worlds that go to war for control of the earth.

The underground world where Zhang Xu is located is called the Dragon Emperor Palace, and the underground world where Adam is located is Heaven.

The dimensional space where Heaven is located has occupied the Earth for five hundred and sixty-five years, and during these five hundred and sixty-five years, Heaven and the rest of the underground worlds have fought countless times, devouring nearly a thousand underground worlds, large and small, and the progress of interaction with the Earth has reached the point where it is nearing the end.

It can be said that under the combined action of Heaven and Earth, they have reached the point where they can prevent the rest of the dimensional space from descending to the same level as Heaven.

In other words, as long as there is enough time, Heaven will be able to completely assimilate with the Earth sooner or later.

But in the five hundred and seventy-fifth years of the Heavenly Calendar, the advent of a dimensional space disrupted Heaven's plans.

The name of this dimensional space is ...... Dragon Mound.

According to legend, the green dragon and the white tiger Xuanwu are the four sacred beasts of the earth's space order.

Because the earth is the core of the entire multiverse, it needs the green dragon Vermilion Bird and the white tiger Xuanwu to guard the spatial order, and the division is mostly in the major dimensional spaces that originate from the universe, because of the attraction of the core position of the earth, it constantly descends on the center of the earth and starts a battle for the earth.

Hundreds of billions of years later, under the conquest of the entire multiverse, the earth was overwhelmed, and the four holy beasts of the green dragon and white tiger Xuanwu launched the power of the four origins when the earth was about to be destroyed, and at the critical moment of maintaining the earth's spatial order, they were severely damaged and fell by the powerhouses of the rest of the universe.

After the fall of the four major spatial order holy beasts of the Blue Dragon Vermilion Bird and the White Tiger Xuanwu, the spatial position of the earth was not protected, and it was excluded by the multiverse except for the core of the universe.

The corpse of the Blue Dragon Vermilion Bird White Tiger Xuanwu took away the four cornerstones of the earth that contained the greatest source power, and turned into the dragon mound Nestle Tiger Tomb Ruins, scattered to various parts of the multiverse, and after the waiting earth recovered its vitality, it returned again and the earth returned to its origins.

In the process of interacting with the earth, Heaven restored a quarter of the earth's vitality, attracting the dragon mound hidden in a corner of the multiverse.

Although Heaven has obtained part of the will of the earth and can repel the arrival of the rest of the dimensional spaces, it cannot prevent the earth's origin from becoming one, so the dragon mound has successfully descended on the same latitude of the earth and interacted with the earth.

The return of the dragon mound is naturally not just the return of this dimensional space......

In the dimensional space of the dragon mound, there are also the aborigines of the dragon mound...... Dragon Emperor Palace!

But Heaven did not launch an offensive against the Dragon Emperor Hall at the first time, because in order to gain control of the Dragon Mound, they had to open the Dragon Mound and take away the bones of the Green Dragon.

Only by obtaining the bones of the green dragon can you get control of the dragon mound, so that the dragon mound can be incorporated into the dimensional space of heaven and further enhance the compatibility with the earth.

But the opening of the dragon mound must require the instructions of the hall of the Dragon Emperor Palace, not only that, but also ten years later, after the consciousness of the green dragon in the dragon mound is eliminated, the dragon mound can be opened later.

Therefore, in the past ten years, Heaven can only recruit the Dragon Emperor Palace.

Nominally, Heaven recruited the Dragon Emperor Palace, but in fact, they only suppressed and monitored the people of the Dragon Emperor Palace.

Ten years later, that is, in the five hundred and eighty-fifth year of the Heavenly Calendar, after the Dragon Tomb was opened, the Dragon Emperor Hall took the lead in launching an attack on Heaven in the Dragon Tomb.

In the past ten years, due to the integration of the origin of the Dragon Tomb and the earth, the degree of interaction between the Dragon Tomb and the earth has been higher than that of Heaven in the past five hundred and eighty-five years.

So much so that the overall strength of the Dragon Emperor Hall was even higher than that of Heaven.

Under the offensive of the Dragon Emperor Palace, it is heaven that is losing and retreating!

When the Dragon Emperor Hall and the people of Heaven were fighting in the Dragon Mound, the Hall of the Dragon Emperor Hall and the head of Heaven, Adam, started a battle for the green dragon bone in the Dragon Mound, because if he won the dragon bone, even if he won the approval of the Dragon Mound, he was recognized by the Dragon Mound, even if he occupied the origin of the earth.

The side that fights in this dimension of the earth and obtains the power of the earth's origin will naturally be able to suppress the other party in terms of strength in an instant!

Although the strength of the Dragon Emperor Hall vaguely overwhelmed Heaven, because of the background, the strength of Adam, the head of Heaven, was much stronger than that of the Dragon Emperor Palace.

Adam won the keel, but because Zhang Xu was the original of the dragon mound, even if the keel was taken away by Adam, the keel recognized Zhang Xu more!

So at a critical time, Zhang Xu forcibly devoured the keel, fused with the keel, and at that moment, he followed the power of the green keel and killed Adam, but because of the backlash of the green keel, Shen Zhang Xu slept for three years.

It wasn't until three years later that Zhang Xu completely dissolved the backlash of the green dragon bone and woke up.

Since then, because of the integration into the Dragon Mound, the interaction between the Dragon Emperor Hall and the Earth Dimension has reached an unprecedented level, and the Dragon Emperor Hall has even reached a point where Heaven has not been able to do it, completely occupying the dimensional space of the Earth.

However, by occupying this dimensional space, the origin of the earth has once again returned to a new level.

The moment the Dragon Emperor Hall took over the dimensional space of the earth, it had already sensed that Nestle was already moving towards the earth!

After experiencing the battle with Heaven, the Dragon Emperor Palace, which occupies the magpie's nest, naturally understands better than Heaven what kind of crisis the arrival of Nestle will bring to the Dragon Emperor Palace, so when the Dragon Emperor Palace receives the mess of Heaven, it is beginning to prepare for the arrival of Nestle.

The Dragon Emperor Hall first established a complete system of the underground world in the above-ground world, and created a new environment of the underground organization on top of this system, cultivating and recruiting new special functions in addition to the natives of the Dragon Emperor Palace.

As for why the special function and underground organization were established, it is because the power of the underground world can only be used in the dimensional space of the underground world, and once it leaves the underground world, the power of the underground world cannot be used, and even the current controller of the earth, the Dragon Emperor Palace, can only abide by this rule.

But because of the existence of the dragon mound, everything related to the dragon can be used in the earthly world, and the dragon qi unique to the Dragon Emperor Palace, the dragon bone on Zhang Xu's body, is not restricted by the rules, which is why even in the earthly world, the Dragon Emperor Palace is still the well-deserved king of the world.

At this moment, Zhang Xu's broad back cracked again in an instant, and Lin Xian gently slipped out of Zhang Xu's back.

Zhang Xu hugged Lin Xian very gently, looking at Lin Xian's eyes, in addition to gentleness, there was also an unknown strangeness.

The reason why the Dragon Emperor Hall is looking for people with special functions and recruiting people with special functions who are suitable for the Dragon Emperor Hall into the Dragon Emperor Hall is because only those with special functions that are perfectly compatible with the origin of the earth will be suitable for the Dragon Emperor Palace, and the people who are suitable for the Dragon Emperor Palace...... Nature is equally suitable for Nestlé.

After the Dragon Emperor Hall took over the rule of Heaven, it reached a high degree of compatibility with the origin of the earth, so it learned more secrets about the Blue Dragon Vermilion Bird and White Tiger Xuanwu.

Except for the aborigines in the dragon mound, the rest of the Nestle Tiger Tomb Ruins were separated from the origin of the earth, and there were no aborigines on it, and the descendants of the Vermilion Bird White Tiger Xuanwu remained on the earth.

After the Nestle Tiger Tomb returns to Earth, the descendants of these holy beasts will awaken their bloodline.

And the Dragon Emperor Hall is looking for people who are suitable for the Dragon Emperor Palace, in order to recruit all these descendants into the Dragon Emperor Hall before the return of the Nestle Tiger Tomb, so that even after the bloodline awakens, they cannot escape the control of the Dragon Emperor Palace, and then strangle the crisis of the Dragon Emperor Palace in the Dragon Emperor Palace.

Because joining the Dragon Emperor Hall is equivalent to integrating into the underground world of the Dragon Emperor Palace, as long as you integrate into the underground world, you are a member of the underground world, and it is impossible to separate from the underground world again.

As for the reason why Zhang Xu's gaze at Lin Xian suddenly had a strange look at him at this moment, because when he separated Lin Xian from his back, he felt the power of the same origin from Lin Xian's body.

And Zhang Xu is the only remaining descendant of the Green Dragon, and there is only one possibility that he has the same origin power as him...... Descendants of other sacred beasts!
