Professor Zheng's light and shadow froze again for a while, and he resumed his smile, saying: "The term 'humanity' has multiple meanings of biology, culture, politics... I can only say that from a biological point of view, people on earth There is no reproductive isolation between most of the intelligent races in the Immortal Cultivation World and the Illusory Demon World, including the orcs, sea races, and mermaids in the Illusory Demon World."

"Even mermaids aren't reproductively isolated?"

Chu Ge and Shi Meng stared at each other, thinking for a long time, but still found it inconceivable, "But... how to do it?"

This time, Professor Zheng's light and shadow completely froze.

After a full three seconds, he said bluntly: "This is a good question, students are welcome to think independently, the next question."

"All right."

Chu Ge scratched his hair, "That is to say, the humanoid intelligent life in the three worlds originally came from the same source? Then how did we disperse to the three worlds and develop completely different power systems? There is no magic in the Immortal Realm, there is no magical power in the Phantom Demon Realm, and there is only technology on Earth?"

"The answer to this question is still confusing and hidden in the thick fog, but the academic community has also thrown out many hypotheses. The first thing to be clear is that the ability of human migration is far beyond the imagination of all of us."

Behind Professor Zheng, the light and shadow changed, and a picture of the ancient earth hundreds of thousands of years ago emerged.

In the picture scroll, on a hot continent with luxuriant water and grass and wild beasts, a group of hunchbacked, hairy and blood-drinking primitive people, armed with stone spears and stone axes, are chasing the herd of beasts and migrating northward.

This is the picture of the ancestors of human beings going out of Africa and spreading to the whole planet.

"As early as in the wild and ignorant years, our ancestors did not have any modern weapons, paved roads or any automatic means of transportation. Relying on simple stone spears and two feet, our ancestors walked out of the land where they were originally conceived step by step. , to the plains, to the mountains, to the sea, to the rainforest, and to the thousands of miles of frozen snowfields, embarking on a courageous migration path.”

Professor Zheng said, "In the tens of thousands of years that followed, human beings traveled all over the habitable land on this planet, and drove out all the large beasts there, becoming the master at the top of the food chain.

"Even the vast ocean can't stop the progress of human beings. With only the simplest canoes, human beings are scattered on the archipelago deep in the ocean.

"But at this time, human beings are far from inventing the concept of 'country', let alone 'empire expedition'.

The people scattered all over the place are completely unaware that they, as a unified civilization, are developing an unprecedented hegemony on this planet.

"Thus, the human beings who scattered and began to settle in various places stopped their progress and gradually closed themselves. According to the local environment and climate characteristics, they developed distinctive cultural customs, social forms, moral laws, and even skin color. And looks are very different.

"In this way, when the darkness of the Middle Ages was about to pass and the era of global discovery came again, human beings scattered all over the world saw their own kind for the second time after tens of thousands of years.

"But at this time, people who are completely different in appearance and spirit find it difficult to recognize each other as their 'compatriots'—when the Francois riding tall horses and holding arquebus guns find that they are wearing gorgeous feathers and using living people When offering sacrifices to the Incas, I am afraid that they never thought that the other party might be their compatriots. If they were all familiar with the concept of 'alien' at that time, they would definitely regard each other as aliens."

Chu Ge thought for a while, and said, "You mean, the relationship between the people on Earth and the natives of the Immortal Realm and the Illusory Demon Realm is like the relationship between the Franks and the Incas? Could it be that the intelligent beings in the Immortal Cultivation Realm and the Illusory Demon Realm are also very It slowly spread out from the earth tens of thousands of years ago?"

"As a possibility, why not?"

With a wave of Professor Zheng's hand, a picture of thousands of miles of ice and thousands of miles of snow drifting appeared behind him. In the ice and snow, a group of human beings wrapped in thick fur were trekking hard, crossing the mottled rock formations between the ice sheets.

"During the prehistoric age between 10,000 and 30,000 years ago, at the end of the last Ice Age, the land bridge between Siberia and Alaska was revealed, and the ancient ancestors inadvertently crossed the land bridge in the process of chasing their prey, and entered the The American continent has since opened the bloodiest page in the American continent. In just a few thousand years, it has occupied all the land suitable for living in North and South America. This is evident from the strong ability of human beings to traverse and colonize.

"Let's let go of our imaginations. What if these ancient ancestors crossed not the land bridge between Siberia and Alaska, but a gap in time and space? What if the opposite of the gap in time and space is the realm of cultivating immortals or the realm of fantasy and magic? How about a paradise that is more suitable for living than North and South America?

"Because they don't know much about the Immortal Cultivation World and the Illusory Demon World, many people think that they are two extremely distant and hard-to-reach foreign lands—in the concept of the three-dimensional universe, this may be the case, but with the space Gap, or "four-dimensional bridges" to communicate with each other, most likely, crossing to another world is easier than crossing the land bridge under the ice and snow and crossing the ocean with a canoe."

This is true.

No matter the little palace master or Dongman Tie Zhu, they traveled to the earth without any effort.

Judging from the words of "Colonel" Ning Lie, the main danger for people on earth to travel to another world is not in the process of crossing.

After transmigrating, although the little palace master felt that the air was dirty and the concentration of spiritual energy was too low, she could still breathe normally, and the food on the earth did not cause her much trouble.

This shows that the similarities between the earth, the world of cultivating immortals and the world of phantoms far outweigh the differences.

Even if the primitive people who were tens of thousands of years ago accidentally traveled to the world of cultivating immortals or the world of illusion, would it be possible to survive?

"The barbaric era tens of thousands of years ago was very different from today's environment. Many experts and scholars believe that it was an era when the earth was full of aura and even flooded. Perhaps at that time, between the earth and the world of immortality and magic, There are countless very stable space gaps, like very safe and fast passages, which can help the ancient ancestors to cross the past with ease."

Professor Zheng said, in the picture behind him, on top of the ice and snow, suddenly appeared a very weird mirror with a height of 100 meters and perpendicular to the ground.

In the picture, the ancestors wrapped in thick fur and holding stone spears and bone blades first worshiped the mirror, then approached the mirror curiously, and threw the stone spears and bone blades tentatively. As a result, the mirror Mercury ripples appeared on the surface, and the stone spear and bone blade disappeared.

Finally, a daring ancestor cautiously stretched his hands to the mirror, first his hands, then his arms, shoulders and head, and he passed through directly.

After a while, many clansmen were still terrified, so he jumped out of the mirror with a fat prey in his hand, danced and said something happily, and then, the whole group of clansmen followed him, and through the mirror, the group traveled to another world !

"Perhaps, when the earth is in the Ice Age when food is scarce and the temperature is extremely low, the Immortal Cultivation World and the Magic World have a comfortable environment and abundant food, and there have never been creatures who are so good at using tools and full of wisdom like humans. Instead of crossing the frozen land bridge for thousands of miles, looking for the elusive life, it is less dangerous to cross into another world.

Professor Zheng said, "A large number of human ancestors traveled to other worlds in this way, took root, sprouted, spread branches and leaves, and became today's cultivating civilization and magic civilization."

"It's just incredible."

Chu Ge murmured, "Even if the space gap really exists, how many ancient ancestors could just discover it and use their courage to pass through it!"

"It doesn't need too many, even hundreds or thousands of people are enough."

Professor Zheng said calmly, "This student probably doesn't have much idea of ​​human reproductive capacity. Although we are not the most fertile species in the whole nature, we are escorted by civilization. The survival rate of young children is the highest of all species, and it was so for tens of thousands of years ago.

"In the battle between early Homo sapiens and Neanderthals, our race was once suppressed to only a few thousand people. However, once we gained the upper hand, we multiplied to seventy in just a few tens of thousands of years. Billion—this is still the result of careful control. If we have enough food and space, even 70 billion, 700 billion will not be a problem.

"So, in the world of cultivating immortals and the world of phantom demons, where spiritual power is more abundant, it is entirely possible that only a few hundred ancestors, after a few hundred generations, will have billions of people, enough to support the development of a civilization."

Although Chu Ge didn't really believe it, but after much deliberation, there was nothing to refute.

"It turns out that we are the ancestors of immortal cultivators and magicians. This thing, the flood rushed into the Dragon King Temple!" Chu Ge said, slapping his thigh.

The little palace master was not convinced.

"Professor Zheng, is this really the case, but I can't believe it!"

She said in Jiao Didi's Mandarin, "According to what you said, people on Earth traveled to the world of cultivating immortals and the world of fantasy and demons tens of thousands of years ago, and became the ancestors of other worlds, but I heard that many myths and legends of other worlds have With a history of hundreds of thousands or even millions of years, it seems that millions of years ago, a prosperous civilization developed in another world - what is going on? Could it be that people from another world crossed over On the primitive earth, how about the ancestors who became the earthlings?"

"Who is this?"

After listening to the young palace lord's coquettish speech, Shi Meng took a serious look at her and asked Chu Ge in a low voice, "Your girlfriend? She's pretty!"

"No, don't talk nonsense."

Chu Ge quickly waved his hand in denial.

He is not a gentleman, he is mainly afraid of the little palace master's Yuanying father, it is better not to make such jokes casually.

"She is very strong, and ordinary men can't bear it. Don't act recklessly, or the consequences will be very serious." Chu Ge kindly reminded Shi Meng.

"oh……"

Shi Meng's eyes flicked back and forth between Chu Ge and the little palace master, nodded and said, "I understand."

I don't know what this seemingly simple and honest guy knows.
