When she came out of the teaching office and returned to the gate of the dormitory, Ouyang Ting was already waiting a little anxious, and when she saw him come back, she said a little coquettishly: "Why have you been there for so long, have you taken a leave of absence?" ”

Jiang Ping nodded, and didn't say much about what happened just now. Ouyang Ting said, "Then let's go." ”

The two went all the way to the cross-sea bridge on the west side of the island, and the guards at the head of the bridge strictly checked the pass sheet presented by Jiang Ping before they were released.

Seeing that the management of entry and exit from the island was so strict, Jiang Ping was a little curious about how Ouyang Ting came in, and asked casually: "Classmate Ouyang Ting, you are not a cadet of the military academy, how can you come in?" ”

Ouyang Ting snorted and said, "The military academy is very strict with the entry and exit management of other outsiders, but for the students of the Federal Interstellar University, it is very polite, and they can enter and exit with the cadet card of the Federal Interstellar University. ”

Jiang Ping couldn't help but ask again: "What is this for?" ”

Ouyang Ting said: "Maybe it's a convention, the two schools are the top schools in the Federation, and they are close neighbors, the relationship between the two schools is very good, and they have a cooperative relationship in many aspects." ”

Jiang Ping smiled and said: "I heard that the female students of the Federal Interstellar University like to find the students of the Federal Military University as boyfriends, and the male students of the Federal Interstellar Military University also like to find the students of the Federal Interstellar University as girlfriends. ”

Ouyang Ting's face was slightly red, glanced at him, and said, "You just came to the military academy not long ago, and there are still a lot of people who know the way!" ”

Jiang Ping smiled and asked again: "I see that you are familiar with the military academy, you should have been here a lot, right?" ”

When Ouyang Ting heard this, her expression suddenly became a little stunned, and she didn't deny it, and said, "Yes, I used to come to you a lot." ”

"Oh, yes." Jiang Ping felt that there might be some story in it, but since the other party didn't mean to say it, he wouldn't gossip about it.

Out of the cross-sea bridge and to the land to the west, Ouyang Ting took out the aircraft she had stored from a nearby hangar.

This is a three-meter-diameter, orange-red personal flying vehicle, which belongs to the most advanced fifth-generation personal flying vehicle, which can reach speeds of up to 10,000 miles per hour, and it only takes more than an hour to run from the Antarctic continent here to the North Pole on the other side of the earth.

It can be said that with such a personal aircraft as a vehicle, the whole earth has truly become a global village. It's not uncommon to travel all over the globe in a day in a flying machine like this.

Ouyang Ting opened the flying machine, and after the two of them entered the aircraft and sat down, Ouyang Ting closed the hatch and turned around and asked, "Jiang Ping, where are you going to go for the first stop of your earth tour?" ”

Jiang Ping thought for a while and said, "This first stop, I want to go to the Yellow River to see." ”

Ouyang Ting smiled and said, "I thought your first stop would be to go to the Great Wall." ”

Jiang Ping said: "The Yellow River is one of the important birthplaces of human civilization, and I am just curious. ”

Ouyang Ting said: "Yes, since this is the case, then our first stop will be the Yellow River."

With a flick of her finger, Ouyang Ting immediately set the destination of the Yellow River on the navigation map of the aircraft, and after everything was ready, she pressed the start button, and a stream of hot charged electricity erupted from the bottom of the aircraft, and the aircraft began to gradually float in the air and accelerate, speeding towards the predetermined destination.

The Yellow River is located in the territory of the ancient Huaxia Kingdom in the northern hemisphere, and there is still a short distance from the Antarctic continent, under the full flight of the aircraft, after more than half an hour, the aircraft came to the roof of the earth, the Qinghai-Tibet Plateau, the northern foot of the Bayankala Mountains, which is the birthplace of the Yellow River.

Ouyang Ting began to reduce the slack speed of the aircraft, and fine-tuned the flight trajectory of the aircraft, so that the aircraft flew all the way along the direction of the Yellow River. …,

Through the transparent window of the aircraft, you can see a meandering river, rushing out of the snow-capped mountains of the Bayankala Mountains, flowing into the distance, and there are constantly tributaries converging and growing along the way.

This is the Yellow River, one of the most important birthplaces of human civilization, which gave birth to the world-renowned Chinese civilization, which still occupies a very important position in the federation.

From the sky, it looks like a lion with its back raised and its head ready to leap, crossing countless lofty mountains and mountains from the Qinghai-Tibet Plateau; across vast plains; Galloping in the mountains and deep valleys, the last turn to the east, into the Bohai Sea.

"Can you land?" Jiang Ping asked softly, he suddenly wanted to come to the bank of the Yellow River and experience the charm of this ancient river of civilization.

"Absolutely." Ouyang Ting pressed the landing button, and the aircraft gradually slowed down, and landed in a flat and open area at the end of the day. Next to it is the Yellow River.

The two stepped out of the aircraft and came to the bank of the Yellow River. Looking at the raging river under his feet, Jiang Ping was slightly surprised and said, "This water is actually clear. ”

He once knew that there were eight bends of the Yellow River in nine bends, a bowl of river water and half a bowl of sand, and there was a saying that the Yellow River was clear to describe impossible things.

Ouyang Ting said with a smile: "The mud and sand turbidity of the Yellow River has been a matter of the old century, and now the Yellow River basin is full of trees and vegetation, and the phenomenon of soil erosion has been cured, and the water of the Yellow River has long been cleared." ”

Jiang Ping nodded. The two then got back on board and continued their journey to Earth.

After cruising the Yellow River, the two went to the Great Wall, the Terracotta Warriors, the Egyptian Pyramids, the Temple of Artemis, the Mausoleum of Mausolus, Angkor Wat, the Taj Mahal, the Lighthouse of Alexandria, the Hanging Gardens of Babylon, the Colosseum and other historical sites of civilization.

In a few days, the two of them visited almost all the well-known scenic spots and historical sites on the entire planet.

After seeing these historical sites, it is very shocking, and it is hard to imagine that such a miraculous building could be built under the conditions of backward scientific and technological civilization in the old century.

For example, the pyramids of Egypt, to this day, there are still many mysteries.

The Pyramid of Khufu, is the largest pyramid in Egypt. The pyramid covers an area of 13.1 acres and is constructed of nearly 2.6 million boulders weighing at least 2.5 tons, totaling more than 6.25 million tons.

In the era when there were no lifting tools, how could workers quickly move and stack stones? The outer walls of the pyramid are clinging to each other so precisely that they are laser-cut, and not even a business card can be inserted; Even with the most advanced modern civil engineering techniques, it is difficult to complete.

The meridian of the Pyramid of Khufu divides the land and the sea of the earth into two equal halves, and from the apex of the Pyramid of Khufu leads a line due north to the north, so that the Nile Delta is equally divided into two halves. If you continue north to the North Pole, you will see that the extension line is only 6.5 kilometers away from the pole of the North Pole, and if you take into account the fact that the position of the Arctic Pole is constantly changing, it is conceivable that the extension coincided with the Arctic Pole when the Pyramid of Khufu was built.

If the circumference of the base of the Pyramid of Khufu is divided by twice its height, the quotient obtained is 3.14159, which is pi, and the total weight of the Pyramid of Khufu is about 60 million tons, which is exactly the weight of the earth if multiplied by 10 to the 15th power!

And so on, the coincidence of these numbers, it is difficult to say that it is all accidental.

In addition, there are a large number of mysterious phenomena and signs of super-high civilization hidden in the pyramids, which makes it difficult to believe that the ancient Egyptian kingdom could have been built by the still stage of slavery.

One of the most incredible is that in the structure of the pyramid, an invisible, special energy can be generated, which was previously called "pyramid energy", this intangible, special energy can make the animal carcasses in the tower become mummies, food is not perishable, the blades are sharp, flowers can bloom forever, and so on. …,

But after Imidia proposed the concept of bioenergy ten years ago, people were surprised to find that this "pyramid energy" is actually bioenergy!

This discovery immediately sparked a new wave of pyramid research. Current research has increasingly disproved the thesis that the pyramids were the result of the blood and sweat of millions of slaves in ancient Egypt, and has increasingly leaned towards two points.

The first view is that the pyramids are the legacy of prehistoric lost civilizations, such as the Atlantean civilization that sank to the bottom of the sea with the prehistoric flood, as well as the Gendana civilization, the Mu continent civilization, and so on.

The second point of view is that the pyramids are simply the work of an alien civilization.

Of the two views, the first is the most credible. By now, some of the prehistoric high-tech remains found on the earth have almost confirmed the existence of prehistoric civilizations.

For example, a 2 billion-year-old large chain nuclear reactor was found in central Africa, a 2.8 billion-year-old metal ball was found in South Africa, and the ruins of a tropical city were found in Antarctica, proving that tens of thousands of years ago, the Antarctic continent belonged to the temperate zone and gave birth to a highly developed civilization. It is quite possible that yet another highly developed prehistoric civilization existed......

In fact, if the current human civilization had not developed a federal form of government in time and formed a unified federal government, it was very likely that in a certain nuclear war in the world or the harsh environmental revenge of nature, it would have become a prehistoric civilization of later civilizations, just like these prehistoric civilizations that once existed on the ancient earth.

Even now, human civilization has developed to an interstellar civilization, but it still cannot be said to be worry-free, although the possibility of an interstellar cosmic catastrophe is very small, but the possible existence of extraterrestrial civilization, or a certain internal turmoil of human beings themselves, may destroy the existing human civilization in an instant, making it another lost civilization that once existed in the universe.

It may be said that the more developed the scientific and technological civilization, the more fragile the existence of the civilization.

Seeing the relics of these ancient civilizations, Jiang Ping couldn't help but have a strange thought in his heart, have these civilizations really disappeared, or are they still continuing in a certain time and space?
