In Bei He's words, there are three main types of people who will come to Beijing University to study modern history.

One is to join in the fun, thinking that the history department of Beijing University has a long history, a long reputation, and is worthy of its name, and those who come to follow the trend have not considered the future development trend at all, which is the majority of people.

The second is the rich second generation, to cultivate sentiment, expand knowledge, learn more real history that other schools can't learn, more to train themselves, and don't have to worry about future work at all.

There is also a simple interest in history.

As a result, although the Department of History is the most difficult profession to find a job in the whole Beijing University, it is also the most special department, and there are many people like the rich second generation in it, who come to exercise on purpose.

Even if most people are not rich second generation, their families are quite rich, and they don't have to worry about finding a job in the future.

Chen Le, on the other hand, belongs to the third type.

He was genuinely interested in history.

I am interested in the evolution of orangutans in the past, the existence of huge dinosaurs with a size of seventy or eighty tons in the past, the amazing ancient Egyptian civilization that once existed on the earth, or the extraterrestrial civilization, and also the birth of the earth and the emergence of life on the earth, from unicellular to multicellular.

Because he thinks it's magical,

How did people change from orangutans to people, and did dinosaurs really become birds, and it was said that humans existed before, so how did they live?

Chen Le is quite curious, and always feels that there are many amazing ingredients hidden in this thick and wonderful history.

Therefore, for the class of Bei He, the counselor who teaches "The History of Human Civilization", I also think very much about it.

Because he finds it interesting.

Bei He drew a few lines on the blackboard and asked, "Okay, in the last lesson, we said that the earth is divided into four eras, who will repeat the four eras of the earth." ”

Then, the girl in front of her raised her hand very actively.

The boys in the back are either playing with their phones or watching a play.

Bei He casually pointed to Peng Lin in the front row, "Come on." ”

Peng Lin shook his ponytail and stood up, with a lively smile on his face, a pair of big eyes that could speak, and said with a smile, "Well, the earth is divided into four eras, first 2 billion years ago, to the ancient age 500 million years ago, also known as the ice age. ”

"Then, from 500 million years ago, to 250 million years ago, the Earth entered the paleontological age. ”

Then, from 250 million years to 80 million years ago, we entered the age of dinosaurs, and dinosaurs became the overlords of the earth. ”

"Finally, 80 million years ago, when the dinosaurs were extinct to the present, the earth entered the era of human evolution, and human beings evolved from apes to humans, and then there was the current civilization. ”

"Hmm. ”

Bei He nodded and said with a smile, "That's very good, it seems that you have reviewed the content of the last few classes, you sit down." ”

"So, since you talked about human civilization, let me ask, who knows how many civilizations mankind has gone through so far. ”

Bei He casually pointed to Chen Le in the back row, "Chen Le, you come." ”

Chen Le knew that Bei He intended to let him participate in group activities more, integrate more into the class collective, actively communicate with everyone, and always point to him in class, let him answer questions, and attract everyone's attention, so that he could better integrate into the collective.

It doesn't look like it's working very well, though.

Chen Le had a very bad reputation because of the previous troubles, fights, and bad reviews......

Chen Le thought about it, stood up, and replied one by one, "It is agricultural civilization, to industrial civilization, to the current information civilization, from the beginning of planting agriculture, breeding animals, controlling animals and plants, to controlling machine production, industrial labor, and now virtual reality, computers rule the world." ”

Bei He smiled and said, "Although, it's not wrong to say that, but these can only be regarded as modern civilizations, so do you know how many civilizations in the last era? Before humans put on clothes, civilizations 5,000 years ago?"

"This ......"

Chen Le really didn't know, "Is it written in the textbook?"

Bei He smiled mysteriously, "No, because this thing has not been proven in concrete practice, and it is still in the stage of research, so there is no way to enter it into the textbook, which is also the unique feature of our History Department of Beijing University. ”

As soon as Bei He said this, Chen Le became interested.

After Bei He finished speaking, he wrote on the blackboard, 12345, 5 columns of numbers, and then drew a circle on 5 and circled it.

He continued, "If we divide it according to historical time, we are now in the fifth civilization, which originated in the two river basins, and historians call our current civilization a scientific and technological civilization, or a spiritual civilization, where human beings use science and technology to achieve progress and pass on the spirit to future generations. ”

"And then, before that. ”

Bei He drew a circle on 4 again, and wrote next to it, "This is the fourth, the Atlantean civilization, everyone should have heard of it." ”

Then Huang Han said below, "It's the Atlantis that sank to the bottom of the sea, isn't it a legend?"

"That being said, some evidence was actually found. ”

Bei He said with certainty, "In the Bermuda Triangle, the bottom of the Atlantic Ocean in the west, traces of this civilization have been found, including the construction of walls and roads, the time is about 10,000 years ago, and even in the manuscripts of the Vatican Pope and the writings of Plato in his later years, there are references to this civilization, and everyone who is interested can pay attention to it themselves." ”

"The characteristics of this civilization are the sun and water, they can greatly use the energy of the sun and water, labor, as for the specific use, it is not clear, it may be similar to waterwheels, solar water heaters and the like, however, there is also a saying that their human body can directly use water energy, and solar energy, far more efficient than the water energy we now drink into the water, and the solar energy obtained by basking in the sun, of course, there is no scientific research yet. ”

These words actually made Chen Le think of the qi he practiced, what kind of qi can he have, now people can also use the qi in the atmosphere, or absorb the qi into the body, to attack and defend, will it be similar to the way the Atlanteans absorb the sun and water?

Naturally, Bei He's words also caused a commotion below.

"It's amazing. ”

"Can those people be directly charged by solar energy, won't they have to sleep?"

"If we drink water, can't we also use water energy?"

"Atlantis, I heard that it's a city in the sea, they were born with water, right?"

"It's not going to be a mermaid......

Bei He clapped his hands, motioned for everyone to stop, and smiled, "Don't you think it's amazing, history, it's so magical, and then, above the fourth civilization of Atlantis, there is also the third civilization, the Muria civilization, which existed thirty-five thousand years ago, and to fifteen thousand years ago, this generation of civilization is characterized by the use of its own energy." ”

"Different from the civilization of Atlantis, the characteristics of this generation of civilization are that it can use the energy of animals and plants, and can use the energy in the atmosphere to improve its own energy and surpass the limits of human beings. ”

Someone joked, "All Supermen?"

Bei He smiled and said, "It seems that this is really the case, it should be regarded as a little superman, it can be regarded as a small climax of physical civilization, do you think that the third civilization is more powerful than the fourth civilization? If the fourth civilization is using external forces, then the third civilization is using the human body's own strength." ”

"Then this second civilization is more powerful than the third civilization, this generation of civilization, called Iokotel civilization, is a civilization with supernatural colors, their strength is not physical, but spiritual, science and technology tree full point spiritual, it is said that this generation of civilization, has done it, the physical body can die, the degree of spiritual immortality, can be reincarnated through our so-called soul energy, that is, the so-called reincarnation, but the spiritual memory is still there, the spirit of this generation of civilization is very strong, can be inherited. ”

"Of course, how strong they are, how they inherit, how they work, then we have to ask them, I don't know, we can only know a little from the ruins that have been found so far. ”

Someone joked, "Will it be the wrong birth and become a pig?" ”

Immediately, the person answered, "Then wait for a monk and go to the west to learn scriptures together." ”

Immediately there was another burst of laughter.

In this regard, Bei He just chuckled, "In the historical circle, there is actually such a saying, Wu Chengen is actually a person from the Iokotel civilization, he still retains the memory of his previous life, and then writes him out in a special way to find companions of the same civilization, because once the companions see this book, they will understand. ”

“......”

These words made everyone quiet down for a while, and when they thought about it, it seemed that it was really possible.

Bei He smiled and said, "Of course, there is another reason for this kind of speculation, which is related to the first civilization we are going to talk about in the end, and this first civilization is very special......
