Pxx Alien is a planet where a variety of organisms are highly thriving. Tens of thousands of years ago, a kind of intelligent creature with the purpose of cultivation, the Annihilation people, gradually grasped the domination of the planet, and the Xian people, who originally advocated scientific and technological civilization, were constantly excluded, so that there was no room for survival.

In the end, the hundreds of millions of people of the Xian tribe were forced to self-proclaim in a city, and in this way, the Annihilation people did not let go of the intention of the Xian people, not only harassing but also trying to kill them.

Since the PXX alien planet is in a resonance period with the Earth, a storm, a flood, or an accident, some creatures fall into the PXX alien planet.

Of course, this exchange is also reversed.

More than 10,000 years ago, the Xian people decided to rebuild their home outside of the PXX alien planet, and the first choice was Earth.

So they took a nuclear-powered four-dimensional material spaceship, and hundreds of thousands of Xian clan immigrants came to the earth with the help of the resonant tide of the two planets......

Ning Ke saw that these aliens in the pool were the first Xian people to come.

After the Duliba people arrived on Earth, they landed safely and softly in the Kunlun Mountains. The spaceship is then unfolded in three dimensions, forming the entire Hidden Realm. The incomplete four-dimensional hull has formed a secret realm.

These Xian people began life on earth.

At that time, the original people of the earth were still in the Stone Age, and they drank blood and were clothed with reeds. Of course, there is no human being who can compete with these Xian people.

When the Xian people arrived on Earth, they encountered an irresistible problem, which led to the termination of the policy of continued immigration......

They have a thorny problem of reproduction.

I don't know how many generations ago, the Xian people did not use natural methods to reproduce, but used artificial wombs to socialize and conceive offspring. When they arrived on Earth, this method of artificial reproduction became difficult.

No matter how much you do and how you improve the technology, in the environment of the earth, artificial breeding of offspring fails.

After hundreds of thousands of clansmen arrived on Earth, only one couple naturally gave birth to a pair of children, and the rest of the clansmen had reproductive blockage.

Is it the radiation of space ions during the interstellar journey, or the cosmic space has changed, or the rules of the universe itself...... In the end, it is not known that, in short, their people will no longer be able to reproduce the next generation.

The couple had children for generations, and eventually there was a blockage of reproduction. When they reached the third generation, the old couple was worshipped as the heroes of the clan and eventually became gods, offering them to worship in the temple.

At this point, the plan of the Xian people to immigrate to Earth from the Pxx alien planet has come to an end.

And the Xian people who came to earth did two remedies:

First, the ancient humans on the earth were used for experiments and grafted their genes, but because the species were too different, the reproduction was isolated, and this plan was quickly abandoned;

The second is to find a way to return to the PXX alien planet. This matter was not planned, it was not easy to come by, and it was even more difficult to go back. They persisted for more than 12,000 years, and only "went back" more than a hundred people, and they were only able to achieve it by sacrificing the lives of the earth cultivators.

To this day, there are still more than a dozen people who are still cultivating in various sects, waiting for their cultivation to reach the true heaven and return to their home planet from the Ascension Platform.

Since they came to control a spaceship made of four-dimensional materials that carried more than 100,000 people, although they landed on the earth softly, it still affected the frequency of the earth's operation, weakened the resonance between the earth and the pxx alien planet, and made the communication between the two planets more difficult.

When the spaceship crossed the interstellar and soft-landed on the earth, it had consumed most of the power it carried, the resonance of the two planets had weakened, and the spacecraft had unfolded in three-dimensional form, and it had become a luxury to easily return to the PXX alien planet.

But that didn't stop the Xian people from wanting to return to their home planet.

The Xian people advocate science and technology, but they are defeated by the Yan people who advocate cultivation. They also spent a lot of money to buy the cultivation skills of the Yan people, the pill recipes for refining pills, the skills of refining weapons, and the obscenity of depicting talismans, etc., but they had no spiritual roots and could not cultivate like the Yan people......

These Xian people who came to the earth found that some of the original human race on the earth were born with spiritual roots. If they can cultivate earthlings who serve them, and then travel to the PXX alien planet, maybe the Xian people who are imprisoned in the isolated city of the PXX alien planet will have a chance to turn over.

There was a time when cultivating cultivators of the indigenous people of the earth became the direction and hope of their research.

But the news from the home planet made them even more disappointed. The cultivated human cultivation power, once they set foot on the PXX alien planet, not only did they not be friendly with the Xian people, but they were close to their opponents, the Annihilation people.

Only then did they discover that there was no reproductive isolation between the earthlings and the Annihilists!

Then they changed their strategy and built secret realms to select monks who were suitable for them to take over.

The earth's aura is scarce, and the regeneration of aura is very slow, and as the cultivation of the law spreads to human society, the number of cultivators has skyrocketed, and soon the earth's aura will not be enough to maintain the cultivation consumption of cultivators.

The Xian people enclosed the space of the four-dimensional spaceship, which could prevent more and more advanced humans from stepping in, and second, to ensure that the spiritual energy in a small area was sufficient.

They established the Hidden Realm.

They discovered a rule, only those cultivators with powerful divine souls could eventually cultivate to the level of the True Heaven, and ordinary monks were rarely able to achieve such an achievement. Therefore, the gate of the secret realm established to test the soul of the monk appeared.

Cultivation resources are always more monks and less food. Their level of science and technology is very developed, and the merits obtained by the Annihilation people are modified to mainly transform their own vitality and can also absorb the aura of the outside world, and then pass it on to the monks of the hidden realm, so as to save the consumption of aura.

Only those monks who have obtained the selection and approval of the secret realm, and have obtained the Sect Master Ring, are completely dependent on the cultivation of the aura.

Therefore, a monk who can wear the suzerain's ring on his finger must be a successful loser.

The Patriarch Ring is not only a sign of identity, but also a guide sign for ascending to the Pxx planet, which is equivalent to a navigator to guide the monk back to the Pxx planet.

In principle, there is no question of snatching, and it can only be used by those who have been ordained by the in-laws themselves.

Therefore, for more than 10,000 years, there have been few successful examples of snatching the Sect Master's Ring in the Hidden Realm.

The lifespan of Xian people is similar to that of humans, and the natural lifespan is generally difficult to exceed 180 years. In the past one or two hundred years, the number of these hundreds of thousands of interstellar immigrants has dropped sharply, and only more than 10,000 remain. In order to prolong their survival, they have been immersed in energy pools for entire centuries.

In this way, there are only a few thousand immigrants left.

Every 12 years, a few Xian people are assigned to the pool to replenish the pool with fresh energy water. Every 60 years, the energy water in the pool is completely replaced.

The aliens that Ning Ke saw lying dormant in the pool, the youngest of them had already exceeded Banzai.

The energy water in the pool comes from the remnants of four chimney-shaped heavy water polymerization reactors.

To Ning Ke's amazement, these four tall chimney-like buildings are a group of heavy water reactors. They provide the hidden world with the energy they need to sustain the climate, the weather, the tightness, the concealment, and the human beings who live in the hidden world.

With the scientific and technological progress of human society in the outside world, the Xian people have spent their brains and material resources in this regard.

These primitive people on the earth who were still stubborn when they were sleeping in the pool had entered the 0.75 level of cosmic civilization when they woke up. This process, according to the historical records of the Xian people, took them a million years.

The current level of civilization of mankind is not terrible, but what is terrible is the terrible speed of development of human beings. If human beings continue to develop at this rate, it will not be long before their hidden and best hidden realms will be discovered and exposed by human beings.

– They have a premonition of this crisis.

The spiritual roots of human beings will age and regenerate. In the past 10,000 years, they have carried out several major blood changes for humans who have been trapped in the hidden realm. Even so, they found that the spiritual roots of the humans who now inhabit the hidden realm were still degenerating.

If you want to cross the stars, from the earth to the PXX alien planet, and be of help to the Xian people society of the home planet, the cultivator's cultivation must reach the end of the True Heaven to be eligible.

Even if he reaches the True Heaven, he is only a minor monk who has just entered the cultivation gate when he arrives at the PXX alien planet. It is conceivable that when a cultivator who is lower than the True Heaven cultivation reaches the PXX alien planet, what is the use of the Xian people?

What's more, those who cultivate to a lower level than the late stage of the True Heaven will also be twisted into powder by time and space when they cross the stars.

Therefore, only when the cultivation has reached the late stage of the True Heaven can it be enough to launch the cultivator's Ascension Stage.

In recent centuries, fewer and fewer people have been able to meet this requirement. They have to secretly allow the hidden world to connect with the outside world, which is small but often works wonders.

It seems that people who enter the hidden realm from the outside world often have higher cultivation talents.

However, for the sake of the concealment of the Hidden Realm, all outsiders who have cultivated in the Hidden Realm must strictly keep the secrets of the Hidden Realm.

And they did a great job of that.

With the use of the heavy water polymerization reactor they built when they first arrived on Earth, the aging of the equipment was a lingering problem. Not only is the basic equipment aging, but even the flying machines (called flying saucers in the outside world) for exploring the earth's cultivation resources are left, and the robots used for work are also limited.

It's not a matter of technology, resources, it's that they don't have the manpower.

Only by soaking in the pool of energy can their life activities be dormant, the aging of the body is weak, and their lives can be prolonged. As soon as you get out of the pool, the clock of life will tick quickly, and no one can stand such consumption!

In order to prevent the sudden intrusion of human beings, who had already mastered nuclear energy, they had to send a small number of surveillance.

This is also an important reason for their downsizing in recent years.

The rest of the Xian people are usually soaked in the pool, and only a few people will come out when they replace the new energy water once every 12 years, and only when they are selected once every 60 years will someone come out......

Even so, the number of their people is declining rapidly.

In this year's secret realm selection, they predicted that it would be good to have two selected. Who Cheng thought that a boy from the outside world came, and the powerful spirit was amazing.

Before Ning Ke entered the secret realm, they got a report.

——The master of the Hengfei Sect of the "Graceful Faction" is the Xian clan who took it 60 years ago. He found Ning Ke, of course he would recommend Ning Ke to the secret realm, and his daughter Hengqian was the role of foil.

The wisp of soul thought he left in Ning Ke's soul was to facilitate the Xian clan's seizure. Who would have thought that Ning Ke used the soul lock ring to contain this trace of soul thought......
