"Aerospace Academy, I'm here!"

Holding a silver suitcase in his hand, standing at the gate of the Academy of Astronautics, Yun Xinghe couldn't help but yell.

The whole planet of Bra, I'm afraid there is no school, there is this school magnificent.

The first thing that catches your eye is a huge building that towers into the sky, two thousand meters high, like a sharpened monument, and the top of it releases a pillar of light that reaches the sky, and the light of the pillar is so bright that at night, almost half of the citizens of the star of Phala can be seen.

Some say it's an interstellar lighthouse, some say it's a planet-level defense weapon, and some say it's a photonic communication base station...... These statements are all wrong speculations.

In fact, this is a monument, a monument to commemorate those pioneers who have made outstanding contributions, this monument, cast with the power of manufacturing the hull of an interstellar battleship, will not decay and decay for hundreds of millions of years, and can even withstand the impact of close-range explosions of medium and low-yield nuclear weapons.

The name of Yun Tianfeng, the ancestor of Yun Xinghe, is engraved in this monument, a more conspicuous position.

Secondly, there are the buildings in this college with unique shapes.

Among these buildings are the miniature academic buildings that resemble the C-class starships of the Federation, the gymnasium facilities that resemble the space annular warehouse, the dormitories that resemble the planetary bases, and even the building parked on the highest hill in the center of the campus, which looks like a colonial mothership, is the library of the Academy of Astronautics.

In fact, this colonial mothership is indeed a genuine colonial mothership, it is the colonial mothership that departed from the home planet Blue Star and arrived at the Pyrra Star more than 1,000 years ago, and the citizens of the Bola Star all call this mothership the "Ark of Civilization", of course, in the upper echelons of the Furuya family, this is called the "Robber Ship".

In addition to the magnificent and unique building, the demeanor and appearance of the seniors who walked around in the Aerospace College made him fascinated and deeply fascinated.

A white uniform woven of special flexible fabric with a zipper in the middle of the chest, collarless, slim, with a black collar on the shoulders, the code name of the department to which it belongs is painted on the right side of the chest, and the school emblem of the Academy of Astronautics - a rocket soaring into the sky.

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

Discipline.

Every move, everywhere, is pleasing discipline to the eye.

"That's where I want to be. ”

Taking a deep breath, Yun Xinghe strode into this academy.

……

Military.

Hellish military training.

In the first three months after enrollment, many people don't know how to survive, and some people can't endure the hardship, so they pack their things directly and choose to give up, which accounts for about 20% of the total number of new students.

Yun Xinghe was as willing as he could, and during the military training, he even had the strength to help Du Xiaopang, Su Jialu, Xianglan Meiqin, these slightly weaker teammates, plus Lan Xiulong, the main partner, their team, ranked first among all the teams, and their performance attracted the attention of the school instructors.

After the end of the military training, at the opening ceremony of the freshmen, the dean of the Academy of Astronautics, an old man wearing a captain's uniform, white hair on his temples, and kind eyes, delivered an impressive speech in front of tens of thousands of freshmen in the activity hall of the colonial mothership:

"Why did we carry out colonization, why did we go so far away and 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 Age of Discovery, it means a point of no return, a point of no return to either conquer a lower civilization or go to war with a civilization of the same level or a higher civilization. ”

"There is no possibility of peace. ”

"Our pace of interstellar colonization is not likely to stop until we suffer a major setback in an interstellar war. ”

"Why do you say that?"

"Resources are limited, even if there are 200 billion star systems in the galaxy, but the ones that really have high colonial development value are less than one thousandth, we will count them as one thousandth, that is, there are 200 million galaxies that can be explored. ”

"This is indeed a lot, but don't forget, in the galaxy, the Blue Star Federation is not the only exception, extraterrestrial civilization, has been proven to exist thousands of years ago, a star 20,000 light-years away from us, within ten years, its brightness completely disappeared can be judged: higher alien civilizations than us, have mastered the advanced technology that we have not yet mastered, and they can use technical means to use the energy of the entire star. ”

"In recent years, our astronomers have also observed some images of interstellar wars, the intensity of the wars, even to the extent of destroying small stars, the most recent war, not even five thousand light-years away from us. ”

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

Scientists estimate that there should be at least 2,000 of them. ”

"What is the size of the Milky Way? As you all know, the diameter of 100,000 light years, because it resembles a flat disk, its area is actually 7.85 billion square light years. ”

"Don't think it's huge, if you divide it by 2,000 and distribute it evenly, the Blue Star Federation can only divide it into a territory of 3.925 million square light years. ”

"And 3.925 million square light-years is just a circular area with a radius of 1118 light-years, even if it still has a thickness of 2000 to 3000 light-years, but in any case, astronomical experts estimate that once the Blue Star Federation comes out of the range and exceeds 1000 light-years, the probability of our head-on collision with a higher extraterrestrial civilization is more than 50%. ”

In other words, this boundless galaxy should belong to the chassis of the Blue Star Federation, but the radius is only more than 1,000 light years. ”

"And so far, the Federation has gone 100 light-years away, and the wealth that should belong to us has been given one thousandth. ”

"The remaining 99%, how much can we get in the remaining thousands of years? I don't know, this requires the efforts of you children, and also pins your hopes on advanced alien civilizations, and don't focus too early on our civilization that has just come out of the cradle planet. ”

"Children, you have caught up with the best pastoral era of the Federation, we don't have to worry about resources, we don't have to suffer huge war casualties, we just need to devote ourselves to opening up more habitable planets for mankind, go as far as possible, don't be easily satisfied, don't stay for a long time. ”

"The names on the monument of the pillar of light are not yet full, and the history books of mankind to open up the frontier of survival have only been written in several volumes, and the historians are racking their brains and trying to use gorgeous and unrepetitive rhetoric to shape the glorious images of human heroes. ”

"And these heroes may be one of you. ”

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

Bang la bang ~ The warm applause from the audience lasted for a long time, and the clouds and stars in it slapped their palms red, and their hearts were boiling.

In addition, what surprised Yun Xinghe even more was that not long after the opening ceremony, the kind-hearted old dean called him over alone and met him.

Inside the office.

"You are the descendant of the pioneer Yun Tianfeng, Yun Xinghe?" the old dean with his hands behind his back turned his head and smiled.

"Yes!

Yun Xinghe stood up, puffed up his chest, and saluted a standard salute, feeling a little surprised, he didn't expect the dean to know his ancestors.

"Your ancestor was a selfless and good man, I have read the records, about him, morally, he can be called a saint and gentleman, but this is also his fatal flaw, he is very smart, but his heart is not hard enough, leaving a lot of troubles......"

The dean's evaluation made Yun Xinghe lower his head, although he knew in his heart that these words were right, but he was still a little uncomfortable.

"I'm sorry kid, I don't mean to offend your ancestor, and I also respect him very much, but when I see you, I seem to see a lot of shadows of the Yun family, including your father, grandfather, and great-grandfather, I have seen them alone, they are all very good, but ......"

The old dean wanted to speak and stopped, but after thinking about it, he still didn't say anything.

"Dean, have you seen my father?"

Yun Xinghe was a little surprised, and hurriedly asked, "May I ask what galaxy my father went to, do you know the dean?"

More than twenty years before Yun Xinghe was born, after leaving his genes, his father left, leaving nothing, and even his aunt Yun Xiaoying had a very vague impression of her father, because at that time, her aunt's age was also very young.

Even if he hasn't spent a day with his father, there are only a handful of photos left, which does not prevent his father from being a big hero in Yun Xinghe's heart.

"I don't know, your father, the original target was the R136A star 75 light years away, five years ago, the quantum signal of the Chenguang was suddenly interrupted, at that time, the Star Exploration Bureau, prepared to inform you of this news, but at that time you were preparing for the high school entrance examination......" said the dean.

"The dean means that my father is ...... Missing?"

Yun Xinghe's heart was shocked, what does it usually mean to be missing, he knows very well in his heart, in the dangerous space, losing contact generally means that something may have happened.

"This is not necessarily a child, the maximum communication distance of the quantum communication device is 10 light years, if the Chenguang does not put down the relay signal base station in time, more than 10 light years, even quantum communication, can not maintain signal entanglement, this is also possible. ”

Of course, the dean actually has a sentence in his heart: the release program of the relay signal base station on the Chenguang is automatic, one is released every 4.9 light years, and it is impossible for the Chenguang to miss two in a row, and the Chenguang is still a top-secret, experimental detection spacecraft with positive and antimatter engines, which is very advanced, even if there will be some failures due to poor reliability, it is impossible to have such low-level failures.

So there are only two possibilities left:

First, there is indeed danger.

2. Intentionally.

In short, this is a mystery, and if you want to solve this mystery, you can either send another manned spacecraft, or launch an unmanned probe to R136A.

Five years ago, the large unmanned probe called "Pioneer 66A" was on its way to R136A at 0.6 times the speed of light.

For no other reason, scientists have discovered that the R136A galaxy has a huge water-rich planet, and there are also traces of intelligent civilizations.

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

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

Yun Xinghe said to the dean.

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

"Yes!

Yun Xinghe saluted again and left the dean's office.
