"Aerospace Academy, I'm here!"

With a silver suitcase in his hand, he stood at the gate of the School of Astronautics, and Yunxinghe couldn't help shouting.

I am afraid that there is no such school, and there is a magnificent school.

The first thing that catches your eyes is a giant building that rises into the clouds, two thousand meters high, like a sharpened monument. The top releases a pillar of skylight. The beam of light is bright. At night, half the citizens of Bura Star almost Can be seen.

Some people say that this giant building is an interstellar lighthouse, some say it is a planetary defensive weapon, and some say it is a photon communication base station ... these statements are all wrong guesses.

In fact, this is a monument, a monument to commemorate those pioneers who have made outstanding contributions. This kind of monument is made of force field alloys used to make the hull of the star warship. It will not decay and weather for hundreds of millions of years. It can even withstand low and medium equivalents. The close-up explosion of nuclear weapons.

The name of Yunxinghe, the ancestor of Yunxing River, was carved on this monument, in a more prominent position.

Secondly, it is the unique building in this college.

Among these buildings, there is a scaled-down teaching building like a federal c-class starship; a gymnasium facility like a space ring warehouse; a dormitory building like a planet base; and even on the top of the highest mountain in the center of the campus, the ship parked like The building of the colonial mothership is the library of the Aerospace Academy.

In fact, this colonial mothership is indeed a genuine colonial mothership. It was precisely the colonial mothership that had arrived from the blue star of the mother star and arrived at Bura Star more than 1,000 years ago. Call this mother ship the "Ark of Civilization". Of course, at the top of the ancient house family, this is called the "boat of the robber".

In addition to the magnificent and unique architecture, the graceful appearance of the seniors and sisters who walked around in the School of Astronautics made him fascinated and fascinated.

A white uniform woven from a special flexible fabric with a zipper on the middle of the chest, no collar, slim fit, black collar on the shoulder, the code of the affiliated department on the right side of the chest, and the school badge of the School of Aerospace on the left-one A rocket rising from the sky.

These seniors and sisters, two people side by side, three people in a row, five people in a row, the pace is uniform, the arm swing is the same.

discipline.

Every move, everywhere, is pleasing to the eye.

"This is where I want to come."

Taking a deep breath, Yunxinghe strode into this academy.

...

Military training.

Hell-like military training.

In the first three months after enrolling, many people didn't know how to get through, and some people couldn't eat the bitterness, just packed things and chose to give up. This proportion accounts for about 20% of the total number of freshmen.

The Yunxing River is as sweet as it is. During the military training, there is even strength to help Du Xiaofan, Su Jialu, Xiang Lan Meiqin and the weaker teammates, plus the main partner Lan Xiulong, their team, in all teams , The results ranked first, the performance has attracted the attention of school instructors.

After the military training, at the opening ceremony of the freshmen, the dean of the aerospace institute, an old man wearing a captain uniform, two temples with white hair, and a kind-hearted, good-looking old man, faced thousands of freshmen in the activity hall of the colonial mothership , Gave an impressive speech:

"Why should we conduct colonial development, and why should we go to such a distant place to build a new home for mankind?"

"Even if it's full of danger, even if it's full of unknowns."

"A humanist who admires the law of the dark forest once said: Once a civilization walks out of the stars and enters the era of the universe of nautical navigation, it means a path of no return, one that either conquers lower civilizations or is at the same level of civilization, Or the road of no return for higher civilizations. "

"There is no possibility of peace."

"Our pace of interstellar colonization is only possible if we suffer a setback in an interstellar war."

"Why do you say that?"

"Resources are limited. Even if there are 200 billion stars in the Milky Way, but there are really high colonial development values, less than one thousandth, we will count it as one thousandth, that is, There are 200 million open galaxies. "

"This number is indeed quite a lot, but do n’t forget that the Blue Star Federation is not the only exception in the galaxy. The alien civilization has been proven to exist thousands of years ago, a star 20,000 light years away. It can be judged that its brightness has completely disappeared within ten years: alien civilizations higher than us have mastered advanced technology that we have not yet mastered, and they can achieve the degree of using the entire stellar energy by using technical means. "

"In recent years, our astronomers have also observed some pictures of interstellar wars. The intensity of the war has even reached the point of destroying small stars. The latest war is less than five thousand light years away from us."

"And according to the famous Green Bank formula, with a probability of one in one million, there are at least 2 million civilizations in the galaxy. How many civilizations have reached the level of the Blue Star Federation?"

"Scientists estimate that there should be at least 2,000."

"What is the size of the Milky Way? You should all know this common sense. A diameter of 100,000 light years, because it looks like a flat disk, its area is actually 7.85 billion square light years."

"Don't think this is huge. If you divide it by 2000 and divide it evenly, the Blue Star Federation can only be divided into the territory of 3.925 million light years."

"And the 3.925 million light-years is just a circular area with a radius of 1118 light-years. Even though it still has a thickness of 2000 to 3000 light-years, astronomy experts estimate that once the Blue Star Federation comes out of the range , More than 1000 light-years, the probability of our head-on collision with higher alien civilization is more than 50%. "

"That is to say, this boundless galaxy should belong to the chassis of the Blue Star Federation, but its radius is more than 1,000 light years."

"And so far, the Federation has gone beyond 100 light-years, and it should belong to our wealth, and it has received one thousandth (in three-dimensional space)."

"The remaining 99%, how much can we get in the remaining thousands of years? It is unknown, this requires the efforts of these children, and also hopes for higher alien civilization, not too early Stare at our civilization, which has just stepped out of the cradle planet. "

"Children, you have caught up with the most beautiful pastoral era in the Federation. We do n’t have to worry about resources, and do n’t have to suffer from huge war casualties. We just need to devote ourselves to creating more livable planets for humanity and walking as far as possible. Go farther, don't be content easily, don't stay for long. "

"The name on the monument of Guangzhu is not yet full. The history books of humans exploring the frontier have only written several volumes. Historians are racking their brains and trying to use gorgeous and repetitive words to shape the glorious image of human heroes. "

"And these heroes may be one of you."

"Go ahead, brave children! The future belongs to you, the glory belongs to you, and the history will eventually belong to you!"

Slap slap ~

The warm applause from the audience lasted for a long time, and the Yunxing River among them was red with the palm of his hand, and his heart was boiling with blood.

In addition, what made Yun Xinghe very surprised was that, shortly after the opening ceremony, this kind-hearted old dean also called him alone and met him.

Inside the office.

"You are the descendant of the pioneer Yun Tianfeng, Yunxing River?" The old dean carrying his hand turned his head and smiled.

"Yes! Dean!"

Yun Xinghe stood up, raised his chest, and respected a standard ceremony. He was a little surprised in his heart. He didn't expect the dean to know his ancestor.

"Your ancestor is a great man who is selfless and selfless. I have read the information about him. Morally, he can be called a saintly gentleman, but this is also his fatal flaw. He is very smart, but his heart is not hard enough. After a lot of trouble ... "

The dean's comments made Yun Xinghe lower his head. Although he knew that these words were correct, he was still a bit uncomfortable.

"Sorry boy, I didn't intend to offend your ancestor, and I respect his person very much. Just when I saw you, I seemed to see many shadows of Yun family, including your father, grandfather, great-grandfather. I have seen them alone, They are all excellent, but ... "

The old dean stopped talking, and thought about it or not.

"Director, have you seen my father?"

Yun Xinghe was a little surprised and quickly asked: "Will my dad go to that galaxy, do you know the dean?"

More than 20 years before Yunxinghe was born, after leaving the genetics, his father left, leaving nothing, even Aunt Yun Xiaoying ’s impression of his father was very vague because at that time, Aunt ’s The age is also very young.

Even if I have n’t been with my father for a day, there are only a handful of photos left, which does not prevent him from being a great hero in Yunxinghe ’s heart.

"I do n’t know, your father, the original goal was the r136a star 75 light years away. Five years ago, the quantum signal of Chenguang was suddenly interrupted. At that time you were preparing for the entrance exam ... "said the Dean.

"The dean meant to say that my father ... was missing?"

Yun Xinghe was so shocked, what does missing usually mean, UU reading www. uukanshu.com knows very well in his heart that losing contact in a dangerous space usually means something might be wrong.

"This is not necessarily a child. The maximum communication distance of quantum communication devices is 10 light years. If Chenguang did not drop the relay signal base station in time, more than 10 light years. Even quantum communication cannot maintain signal entanglement. This is also true. possible."

Of course, there is actually another sentence in the dean ’s mind: the release procedure of the relay signal base station on Chenguang is automatically running, and one is released every 4.9 light years. It is impossible for Chenguang to leak two consecutively, and Chenguang, It is still a top-secret experimental spacecraft equipped with positive and anti-matter engines. It is highly advanced. Even if some failures will occur due to poor reliability, such low-level failures are impossible.

So there are only two possibilities:

1. It is indeed in danger.

2. Do it intentionally.

In short, this is a mystery. If you want to solve this mystery, either send another manned spaceship, or launch an unmanned probe to the r136a star.

Five years ago, the large unmanned detector named "Pioneer 66a" was on the way to the r136a star at a speed of 0.6 times the speed of light.

There is no other reason. Scientists have discovered that the r136a galaxy has a huge water-rich planet, and there are traces of the existence of intelligent civilization.

Such as dozens of pyramid-shaped buildings hundreds of meters high ...

"After that, can I go to my father? I think he may be fine."

Yunxinghe said to the dean.

The dean nodded and encouraged him: "It is possible, kid, but what you need to do most now is to study hard and become an excellent captain!") !!
