"Thieves? Do you mean humans? Or Pokémon?"

Before Guan Liyuan could react, Xiao Ai, who seemed to be equally curious about this, asked directly.

Pheromone said "you", and Xiao Ai had both the human part and the Pokémon part, so Guan Liyuan didn't know whether the other party was talking about humans or Pokémon.

However... because of the various "feats" of humans in the main world, Guan Liyuan was more inclined to blame humans themselves.

But to Guan Liyuan's surprise, Pheromone actually asked back: "Is there a difference?"

"What do you mean?" Xiao Ai and Guan Liyuan vaguely guessed something.

"Isn't this a world shared by humans and Pokémon? After you destroyed this place, you invaded our world again! Don't think... don't think that I will easily forgive you just because you are me..." Pheromone said tangledly.

Pokémon and humans, used to live in a reversed world? What about the present world now? Alien beasts?

Guan Liyuan vaguely realized something, and many of his previous doubts seemed to have been answered...

At this moment, it seemed that the "oasis" in the reversed world had tens or even hundreds of times more vitality than the same green area in the present world. It seemed that it was not that Lao Ka "created" the oasis for refuge, but just preserved the last shelter for himself when this world was "destroyed".

[Enough! ] Lao Ka suddenly spoke up, interrupting Xiao Ai's continued questioning.

[Lao Ka, calm down...] Guan Liyuan soothed.

"Kaka, what's wrong with you?" Xiao Hu Pa, who was also in the oasis, also flew over at this time and circled Lao Ka twice.

Lao Ka was silent for a while, and then sent a voice message to Guan Liyuan: [Actually, these things have nothing to do with you... and have nothing to do with Xiao Ai, Xiao Hu Pa, Xiao Shan and others... But since you are so curious, it's actually nothing to tell you. 】

If it was just that it had nothing to do with Guan Liyuan, maybe Old Ka meant that it had nothing to do with the "visitors from another world", but since he also mentioned Xiao Ai, Hu Pa and others, Guan Liyuan estimated that Old Ka simply didn't want the feud to continue.

【Before, you always thought that humans and Pokémon all live in the so-called "present world" now, right? 】Old Ka asked.

Without Guan Liyuan's answer, Old Ka continued: 【In fact, as the ferome mantis said, we... including humans and most Pokémon, our hometown is now this "reverse world", which was once full of vitality and bred countless lives...】

Probably because he heard the ferome mantis mention the things of the past, Old Ka did not become mystical anymore, but talked to Guan Liyuan about the things of the past.

However, Old Ka seemed to be completely immersed in memories, using too many emotions and sighs...

Excluding Old Ka's sadness, the former glory of this "reverse world" was also displayed in front of Guan Liyuan at this time.

In the distant "long, long time ago", Pokémon and humans lived on this land. According to Kaka, the first humans were not a technological system, but like Pokémon, they pursued their own evolution and possessed powerful power...

At that time, there was no so-called "divine beast" in Pokémon. All Pokémon followed the evolutionary path of the "original beast" and broke through the boundaries of level.

From the perspective of today's world, the ancient reverse world with unimaginable resources and energy is enough to support the existence of the "original beast"...

The ancient Pokémon are based on "races", and the most powerful is the so-called "dragon clan". The King of Heaven, the King of Land, and the King of the Sea, the three most powerful original dragons, defeated powerful enemies one by one, occupied the most fertile territory, and ruled countless subordinate races.

However, in the end, the dragon clan could not escape the fate of "prosperity and decline". If the beginning of the ancient times was the rise of the dragon clan, and the middle period was the domination of the world by the dragon clan, then the late period of the ancient times was dominated by the civil war of the dragon clan.

The King of Heaven and the King of Land had a fierce internal fight. As for the King of the Sea... that is, Old Ka, who is now looking after the miracle seeds with his butt sticking out every day, sometimes mediates, sometimes stands on the side of the King of Heaven, and sometimes stands on the side of the King of Land.

In its own description, among the three ancient dragons, only it loves peace, and it is unknown how much water is in it.

But there is one thing that Old Ka is realistic, that is... after the passage of time, from the perspective of an observer, this long-lasting civil war is inevitable, and it is meaningless to investigate who is right and who is wrong in the events that intensified the conflict.

Fundamentally speaking, the cause of the civil war is the uncontrollability of the "Original Beast System"!

The breakthroughs of the Origin Beasts are more dependent on their own efforts and are not restricted by the outside world. However, after each breakthrough to the next stage, the consumption of external resources will increase exponentially.

In the early ancient times, the strongest dragon race only had thousands of primordial beasts, and there were more ordinary dragon Pokémon. There was no pressure from the external environment. But in the late ancient times, when the dragon race was at its peak, there were 30,000 primordial beasts alone, and even weak Pokémon groups had appeared, and it was impossible to meet the minimum reproduction guarantee...

Even if all the primordial beasts knew that the best way at this time was for all Pokémon not to break through again to avoid increasing consumption of the environment.

But whether it was the dragon race or other races, no race would do this. Only by becoming stronger can they obtain more resources!

Small races without primordial beasts have no living space at all. On the contrary, the more primordial beasts there are, the more they can seize resources and protect ordinary Pokémon of the same race.

This fundamental contradiction cannot be adjusted, which led to some small race wars, which gradually expanded to the Doomsday War.

If this war could simply reduce the number of the original beasts and make all parties in the war feel the pain, perhaps a new order could be established...

However... Unfortunately, the result of the Doomsday War was that the reversed world, which was already on the verge of collapse, completely exceeded the scope of self-repair. Although the number of the original beasts was almost the same as the early ancient times when the ancient times were about to end, the external environment began to gradually "dead"!

In this way, although the number of original beasts decreased, external resources were always insufficient, and the world seemed to have stepped on the accelerator towards complete destruction...

Fortunately, at this time, the first Pokémon finally broke through the limit of the race value and became a "divine beast".

The divine beast can not only have the same power as the original beast, but also has a small burden on the environment. It can even resonate with the rules of the world and become a "beneficial insect" of the world.

Of course, the newly broken divine beasts, like the weakest original beasts, cannot directly turn the tide, but... because they do not need too many resources, they can completely take the ordinary Pokémon in the tribe and live and develop in the corners that the original beasts don't care about.

The appearance of mythical beasts also marks the end of the ancient times and the beginning of the prehistoric era.

In the early ancient times, the mythical beasts were less dependent on the environment and could even nourish the external environment to form a symbiosis, unlike the primordial beasts, which only put pressure on the environment, so they developed in the corners of the world. On the other hand,

the number of primordial beasts has not only been greatly reduced, but the King of Land and the King of Sky died together in the last battle at the end of the ancient times, but they still had to continue the war under the pressure of survival. Although the world is being destroyed, as long as they continue to win, they can make their own tribes not die before the "world".

When the time came to the middle of the ancient times, Chaoparis, the only remaining one of the three ancient dragons, could only move in the areas with the richest vitality in the world. Once entering the area with weak vitality, Chaoparis's physical strength will be quickly consumed, and the areas that meet the requirements account for less than one-tenth of the world.

Similarly, other primordial beasts are also subject to similar restrictions. The more powerful the primordial beasts, the smaller the range of activities.

The tribes that have gradually "become a climate" and have mythical beasts have begun to occupy the world piece by piece!

At first, they could only live in the poor mountains and bad waters where the original beasts "could not survive". Gradually, they began to occupy some areas that the original beast tribe "did not care about". Later, the original beast tribe "out of fear" gave up some of the poorer areas... In the end, the remaining original beasts could only shrink in a few fixed areas.

Compared with the ancient wars between the original beast tribes, the ancient wars in which the mythical beast tribe replaced the original beast tribe were actually much more "harmonious".

Because the starting points of the original beasts and the mythical beasts were both ordinary Pokémon, the process of the mythical beasts replacing the original beasts was not just a brutal war. There were also factors of self-adjustment among the tribes. It can be said that "enemy conflict and self-evolution" coexist.

After all, the environment required by the equally strong original beasts and the mythical beasts is very different. If a first beast wants to survive, it needs to occupy a territory that can allow more than ten mythical beasts to survive. And one original beast and ten equally strong mythical beasts occupy the same territory. Which situation is safer? The conclusion is obvious.

Therefore, in the late ancient times, after discovering the power of the mythical beasts, all races took the initiative to reduce the number of original beasts and intentionally avoided evolving into original beasts.

The same self-adjustment also appeared among humans. Before the ancient times, there was no essential difference between humans and other Pokémon. However, in the ancient times, humans adjusted more thoroughly than Pokémon and directly began to evolve in the opposite direction. At the cost of sacrificing all their strength, the race's demand for the environment was greatly reduced, and at the same time, the buds of technology emerged.

Although technological development depends on environmental resources, when environmental resources are insufficient, it will naturally inhibit the development of technology. Therefore, the stability is much stronger than the original beast system...

At the end of the ancient times, there were only a few hundred original beasts left in the world. The more than 100,000 original beasts in their heyday either died in war or died of time. Only the strongest and longest-lived ones are still alive.

Moreover, these original beasts, including Chaoparis, all entered a deep sleep, which can minimize the consumption of environmental resources. At the same time, because mythical beasts have been born in their respective races, they can sleep peacefully.

At this point, the world entered the Middle Ages of new order and new development. The continuous birth of mythical beasts and the continuous development of science and technology made this world "seemingly" rejuvenated.

When Lao Ka talked about this, his tone was unusually sad...

It can be said that Lao Ka "made an indelible contribution" to the rise of the mythical beasts. When the mythical beast race began to compete for resources with the race dominated by the original beasts, Lao Ka could be said to have restrained himself to the point of "losing power and humiliating the race".

Because he saw new hope from the mythical beasts, Lao Ka would rather watch the dragon race further weaken, and he was always unwilling to extinguish this last hope. If it weren't for the ancestor of the original beast, who had been "tolerating evil", the mythical beasts would have more twists and turns if they wanted to eliminate the original beasts... Even the world might not last until that day!

Facts have proved that Lao Ka's judgment is completely correct. Under its care and suppression, the dragon race gradually has mythical beasts, and no longer evolves into original beasts. Even if the dragon race has lost its dominant position, it can't be said to be in decline...

In the early Middle Ages, Lao Ka was sleeping with expectations for the future.

However, when Lao Ka was awakened, he did not see the world reappearing its ancient glory, but a more desolate world where even breathing was very laborious...

But Lao Ka did not even have a reason to point at the divine beasts and scold them. The reason for this was that the world was too severely traumatized during the ancient war, and the divine beasts could only delay this destruction. At the end of the Middle Ages, when Lao Ka and other original beasts were awakened, this delay was almost at its limit!

However, in this desperate situation, humans created "miracle" technology, which allowed them to discover another dimensional world (from the perspective of the forum, it was just a new plane).

Although the "new world" is even more desolate than the environment of the ancient and ancient times, even compared with the medieval times that are heading towards a dead end, but... the rules of the world there are complete and have not collapsed. In

comparison, the reversed world at that time was like a bottle with only half a bottle of water left and a leaking bottom. The divine beasts could only make the hole smaller. Although the "water" in the new world is less, the container is very complete, and with the special characteristics of the divine beasts, the environment there can be gradually "upgraded".

Moreover, the rules of the new world are still very "simple". In the development of the world, the mythical beasts can make themselves fit the rules, and then change and create the rules to a certain extent.

One side is gradually dying,

and the other side is gradually prospering. This question is not difficult to choose. It's just a bit cruel for the original beasts. The new world is obviously not suitable for them. Humans can only do their best to preserve small oases so that they can sleep in them, and leave a back door so that they can go to the new world when they have enough accumulation.

But in the words of Lao Ka, this is what they deserve. According to the space transfer technology of humans at that time, it is not that everyone can travel through it. In fact, including humans themselves and most Pokémon, they cannot "travel" directly. The new world can only allow the race to continue.

Throughout the ancient times, the theme of humans and Pokémon is the great migration...

The first step is that a few mythical beasts and some Pokémon that adapt to the "new world" enter the new world. First, they experiment to see if they can survive and reproduce. Second, after the mythical beasts go there, they can also gradually "upgrade" the environment of the new world.

There are also some Pokémon that cannot withstand "travel" by themselves, but can enter the fossil resurrection machine after becoming fossils, but cannot pass through. The Pokémon that passed away in the form of fossils can only be said to have left hope in the future.

However... a problem was encountered in the first step. That is, after sending a batch of Pokémon, humans discovered that the time ratio on both sides was different. Before that, they only found a stable space layer and could not conduct too much actual observation.

Fortunately, after joining forces with humans, Arceus can freely travel between the two worlds, which made the humans and Pokémon in the old world discover this.

Under the extremely large time ratio, humans re-adjusted the equipment and studied a way to adjust the time ratio of the two planes to the same, and when they had a new large-scale migration plan, the first batch of pioneers had already reproduced countless generations in the new world.

In the modern world, most of the Pokémon that were born in the billions are the result of the reproduction of these pioneers and the native creatures of the New World.

This is why Guan Liyuan discovered the ancient coelacanth revived from the fossils of hundreds of millions of years ago not long after he came to the Pokémon world, and understood the concept of "human beings", while the fossil pterosaurs of tens of millions of years ago had never seen humans.

Of course, the ancient coelacanth is also unfamiliar to modern humans because compared with the black technology humans it knows, today's humans are no different from those in the Stone Age.

Kyogre, Groudon, and Rayquaza, who live in the Hoenn region, are the descendants of the pioneer beasts. These three beasts are also the only beasts with ancient genes from the New World, so they can enter the form of "primitive return".

Arceus uses his ability to return to the two worlds. He is also the first individual to arrive in the New World in the true sense,

and the degree of integration of rules is also the highest. The difficulties of the great migration have just begun. The second step to "migrate" is the large number of Pokémon that cannot immediately adapt to space travel.

At this time, the time ratio of the two worlds is gradually shrinking, but it is still very large.

If you want to travel directly through the world, you need to wait until the time ratio is completely consistent. Judging from the speed of environmental deterioration at that time, even humans who are least dependent on the environment cannot last until then.

It is called migration... In fact

, the second step is just to make the race continue! Humans created Mew at this time. No one knows about it now. Only some of the longest-lived mythical beasts know that "Mew" is the first artificial Pokémon in the true sense.

Although "Mew" does not have the power of mythical beasts, it has the genes of all Pokémon!

At that time, the only way that humans and Pokémon could think of was to make the race continue in the form of genes...

Although they could not send these Pokémon individuals over, they could send their gene inducers over!

Two million years ago in the new world, because of the intervention of the pioneer mythical beasts, many new lives had appeared in the new world. It was also two million years ago that a special "rain" fell in the new world. This rain induced the local life and quickly evolved in the direction of Pokémon. Even within a few hundred years, the races that originally belonged to the reversed world appeared explosively.

Mew is the monitoring and supplement mechanism of this evolutionary process. They are the most complete gene pool. Some races did not evolve during this period, but because of the existence of Mew, they were able to reproduce the "lost" genes through reproduction...

When there were many races missing at the beginning, Mew reproduced to several thousand at most, and when the "checking for deficiencies and filling in the gaps" was gradually completed, the number of Mew began to decrease sharply. Their reproduction was in accordance with this law.

This is also the reason why in some legends, Mew is the ancestor of all Pokémon and Arceus is the god of creation.

The third step is the migration of humans themselves...

Humans have been dragging this step for a long time, because unlike Pokémon, what humans really want to pass on is their own technology, not genes. Otherwise, they have to evolve from apes again, which is no different from starting from scratch.

Humans who have given up all their power are not only unable to evolve in a simple and crude instant and in the form of individuals like Pokémon, but their "knowledge" is also not something that can be passed on with genes.

However, in the end, humans still did not find a feasible solution. In the end, starting from 100,000 years ago in the new world, a group of primates began to evolve and rushed towards "humans"...

As for human technology, only a small part of it was successfully brought to the new world by the mythical beasts, which is the remains of the super ancient civilization.

Although it is impossible for the humans in the new world to directly inherit the black technology of their predecessors, the super ancient relics have greatly accelerated the development of mankind .

If that's all, it can't be called human efforts. You must know that the great migration is the most laborious and meritorious for humans, but in the end, humans lost the most...

So the mythical beasts who migrated first, when guiding the formation of the rules of the new world, greatly favored humans.

At the same time, in order to avoid the recurrence of the war tragedy of ancient times, the first generation of mythical beasts also set great restrictions on the battles between Pokémon, and tried their best to avoid Pokémon from hurting each other...

Over the past 100,000 years, humans have gradually appeared, and because of the "preference" of the world rules, even if they have no power, they can conquer other Pokémon and accelerate the growth of Pokémon.

Although there were some detours during this period, such as the Pokémon War in the Savage Age, and the giant man who broke the gene lock once again after Carlos appeared, but with the rule bias and the care of some ancient beasts, humans grew rapidly. Among the beasts that migrated directly from the old world, some were powerful and long-lived, and they are still alive today!

For example, Arceus, Zygarde, and the ancestor Rayquaza...

The reason why Old Ka showed fear but not respect when he mentioned Arceus was because Arceus was the first beast that opened the ancient times. At the beginning of the great migration, it was the only beast that could freely travel between the two worlds after joining forces with humans. It was also the beast that combined the most rules...

In the ancient times, Old Ka and Arceus were the bosses of the two camps. Although Old Ka always "tolerated" him rationally, and even Arceus understood this, Old Ka naturally would not have a good tone when mentioning the guy who replaced his era.

In comparison, Kaka hated Zygarde even more. The real Zygarde was the first divine beast of the dragon race. Although Kaka's own "condonation" factor was also involved, when Zygarde broke through the divine beast, the original beast race and the divine beast race were still in a hostile state, so it was a naked surrender to the enemy.

When Kaka heard the news that the dragon race had a divine beast, his first reaction was excitement. That was a sign that he truly realized that there was still hope for the world and the dragon race.

But when he really heard and saw Zygarde, he was still instinctively unhappy. Even though he expected the dragon race to have more divine beasts and directly began to encourage other dragons to evolve into divine beasts, he also wanted to kill Zygarde, the traitor.

Therefore, the dragon race had wanted it at the beginning. Zygarde would evolve the ability to disperse itself into cells, which was also the proof of its struggle for survival. The real Zygarde had been physically destroyed, but its will could only continue through "Zygarde", a race that reproduced by splitting and could be re-integrated.

Even though the two sides have reconciled, the equally unruly Zygarde still holds a grudge against his former boss.

As for the fact that Pokémon "sleep" and become petrified in the Dead Land of the Reversed World, it is also the "credit" of humans.

At that time, between the first and second steps, humans still wanted to delay as much as possible until the time of the two worlds synchronized, so that the spatial resistance would be reduced and everyone could naturally move directly. This petrified state is the result of humans' transformation of the Dead Land...

However, this plan still failed, because the petrification state was studied to the extreme, which only reduced energy consumption and could not truly exist forever.

However, today when the time ratio has been synchronized, the combination of petrification and super ancient space technology has given birth to the "Poke Ball", which can be regarded as an unexpected surprise.

As for the alien beasts... they are native creatures of the "New World", and perhaps some of the blood of the pioneers has been mixed in.

Most of the native creatures of the New World have either combined with Pokémon or have long been integrated into Pokémon, such as the fossil pterosaur and the proto-turtle... They are all Pokémon with local genes as the main genes.

Even now, most of the Pokémon are actually evolved from local creatures...

But there are always ten native races that firmly believe that the evolutionary products under this catalysis are "thieves", and their attitude is never to coexist and reconcile with humans and Pokémon, which is the current ten major alien beasts.

Because they never mate with Pokémon or humans that appeared in the past two million years, their blood only contains the protozoan part and the part of the predecessor Pokémon, so when they enter the old world, they will not be affected by the petrification effect. Humans developed petrification technology after the first step of migration.

After they found a way to pass through the old and new worlds, they would rather use the withered old world as their home, constantly fighting with Pokémon and humans, and Pokémon and humans don’t have much better ways. They will be directly petrified when they enter the dead land of the old world!

The alien beasts only move in Kalos and Alola. In addition to the fact that they have discovered a passage that can shuttle between the old and new worlds in these two major regions, and will lose strategic depth in other regions, it is also because they at least "accept" the ancestors Rayquaza, the ancestors Groudon, and the ancestors Kyogre...

If there were no these predecessor beasts, the "new world" would not have developed to the current level, and they would not appear.

Therefore, there is also an agreement between the alien beasts and the three predecessor ancestors that they will not enter the area centered on Hoenn. Kalos and Alola, which are far overseas, are not within this range...
