"Aerospace Academy, here I come!"

Standing at the gate of the Aerospace Academy with a silver suitcase in his hand, Yun Xinghe couldn't help but yell.

I'm afraid there is no school like that in the entire Star of Bora, as majestic as this one.

The first thing that catches the eye is a huge building that towers into the clouds. It is two thousand meters high, like a sharpened monument. The top releases a beam of light reaching the sky. The beam of light is so bright that at night, half of the citizens of the Star of Bora are almost invisible. All can be seen.

Some say this giant building is an interstellar lighthouse; some say it is a planet-level defense weapon; others say it is a photon communication base station... These claims are all wrong guesses.

In fact, this is a monument, a monument to commemorate those pioneers who have made outstanding contributions to mankind. This kind of monument is cast from the alloy alloy used to make star battleship hulls. It will not decay and weather for hundreds of millions of years, and can even withstand corrosion. Close-range explosive impact of low- to medium-yield nuclear weapons.

The name of Yun Xinghe's ancestor Yun Tianfeng is engraved on this monument in a more conspicuous position.

Secondly, there are the unique buildings in this college.

Among these buildings, there are miniature teaching buildings that look like Federation C-class starships; gymnasiums that look like space annular warehouses; dormitories that look like planet bases; and even the one parked on the top of the highest mountain in the center of the campus looks like a colonial mothership. The building on the ship is the library of the Aerospace Academy.

In fact, this colonial mothership-like building is indeed a genuine colonial mothership. It is the colonial mothership that set off from its home star Blue Star and arrived at Bora Star more than 1,200 years ago. Citizens of Bora Star , called this mothership the "Ark of Civilization". Of course, the senior leaders of the Furuya family called it the "robber's ship".

In addition to the majestic and unique buildings, the graceful appearance of the seniors walking around in the Aerospace Academy made him fascinated and fascinated.

A white uniform made of special flexible fabric with a zipper in the middle of the chest. It is collarless, tight-fitting, and has a black collar on the shoulders. The code of the department is painted on the right side of the chest, and the school emblem of the Aerospace Academy is painted on the left side - a A rocket soaring into the sky.

These seniors, two side by side, three people in a row, and five people in a row, all have the same pace and the same swing range of their arms.

discipline.

A pleasing discipline can be seen in every move.

"This is where I want to be."

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

…

Military training.

Hellish military training.

In the first three months after enrolling, many people don't know how they survived. Some people couldn't bear the hardship and just packed up their things and chose to give up. This proportion accounts for about 20% of the freshmen.

However, Yun Xinghe was very happy with it. During the military training, he even had the strength to help his weaker teammates such as Du Xiaopang, Sugaru, and Xianglan Mikoto. Together with Lan Xiulong, the main partner, their team was the best among all teams. , ranked first in performance, and his outstanding performance attracted the attention of all instructors.

After the military training, at the opening ceremony for freshmen, the dean of the Aerospace Academy, an old man with white temples and a kind-faced man wearing a captain's uniform, faced tens of thousands of freshmen in the activity hall of the colonial mothership (library). delivered an impressive speech:

"Why do we carry out colonization? Why do we go to such remote and desolate places to build a new home for mankind?"

"Even though it's full of danger and unknown."

"A humanist who admires the law of the dark forest once said: Once a civilization steps out of the star and enters the age of space exploration, it means a road of no return. It is either conquering lower civilizations or competing with civilizations of the same level. Or the point of no return when war occurs in higher civilizations.”

"There is no possibility of peace."

"Our pace of interstellar colonization will only be stopped if we suffer a heavy setback in an interstellar war."

"Why do you say that?"

"Resources are limited. Even if there are 200 billion star systems in the Milky Way, the number of truly high colonial development values ​​is less than one-thousandth. We will calculate it as one-thousandth. In other words, it can There are 200 million star systems developed."

"This number is indeed quite large, but don't forget that the Blue Star Federation is not the only exception in the Milky Way. Alien civilizations have been proven to exist thousands of years ago, and there is a star 20,000 light-years away from us. , its brightness completely disappeared within ten years, and it can be judged that there are more advanced alien civilizations than us, and they have mastered advanced technologies that we have not yet mastered, and they can use technical means to utilize the energy of the entire star."

"In recent years, our astronomers have also observed some scenes of interstellar wars. The wars were so fierce that they even destroyed small stars. The most recent war was not even five thousand light years away from us."

"According to the famous Green Bank formula, with a probability of one in a million, there are at least 2 million civilizations in the Milky Way. These civilizations have different levels of technological development. How many civilizations have reached the level of the Blue Star Federation? Woolen cloth?"

"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. It has a diameter of 100,000 light-years. Since it is shaped like a flat disk, its area is approximately 7.85 billion square light-years."

"Don't think this is a big deal. If you divide it by 2,000 and distribute it evenly, the Blue Star Federation will only be able to get an area of ​​3.925 million square light years."

"And 3.925 million square light-years is just a perfect circular area with a radius of 1,118 light-years. Even though it still has a thickness of 2,000 to 3,000 light-years, in any case, astronomical experts estimate that once the Blue Star Federation moves out of the range , more than 1,000 light-years away, the probability of a head-on collision with an advanced alien civilization is more than 50%."

"In other words, this boundless Milky Way should belong to the Blue Star Federation, but its radius is only more than 1,000 light-years."

"So far, the Federation has gone 100 light years away, and has obtained one thousandth (in three-dimensional space) of the wealth that should belong to us."

"How much of the remaining 99% can we get in the remaining thousands of years? We don't know. This requires the efforts of you children and your hope in advanced alien civilizations. Don't be too early. Keep an eye on our civilization, which has just emerged from its cradle..."

"Children, you have caught up with the most beautiful pastoral era of the Federation. You don't have to worry about resource shortages, and you don't have to grieve for suffering huge war casualties. You just need to be single-minded, open up more habitable planets for mankind, and travel as far as possible. Stay far away, don’t be easily satisfied, and don’t stay long.”

"The names on the monument of the pillar of light are not yet fully engraved. The history of mankind's expansion of the frontier of survival can only be written in several volumes. Historians are racking their brains and trying to use gorgeous and non-repetitive words to portray the glory of human heroes. Image.”

"And these heroes may be one of you."

"So, move forward! Brave children! The future belongs to you, the glory belongs to you, and history will eventually belong to you!"

Bang bang bang~

The audience's warm applause lasted for a long time, and the newly born Yun Xinghe's palms turned red, and the blood in his heart boiled extremely.

In addition, what surprised Yun Xinghe even more was that shortly after the opening ceremony, the kind-hearted old dean called him over alone to meet with him.

Inside the office.

"Are you a descendant of the pioneer Yun Tianfeng, Yun Xinghe?" The old dean, with his hands behind his back, turned his head and asked with a smile.

"Yes! Dean!"

Yun Xinghe stood up, puffed out his chest, and gave a standard salute. He was a little surprised. He didn't expect that the dean knew that Yun Tianfeng was his ancestor.

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

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

"I'm sorry, kid. I didn't mean to offend your ancestor, and I respect him very much. But when I saw you, I seemed to see many shadows of the Yun family, including your father, grandfather, and great-grandfather. I have all met them individually. They are all very good, but..."

The old dean hesitated to speak. After thinking about it, he still didn't say anything.

"Dean, have you met my father?"

Yun Xinghe was a little surprised and asked quickly: "Excuse me, which galaxy my father went to, Dean, do you know?"

More than 20 years before Yun Xinghe was born, his father passed away after leaving behind his genetic genes, leaving nothing behind. Even his aunt Yun Xiaoying had a very vague impression of his father, because at that time, My aunt is also very young.

Even though he had never spent a day with his father, there were only a handful of photos left. This did not prevent him from saying that his father was a great hero in Yun Xinghe's heart.

"I don't know. Your father's original target was the R136A star 75 light-years away. Five years ago, the morning light's quantum signal was suddenly interrupted. At that time, the Space Exploration Agency was ready to inform you of the news. But at that time you were preparing for the high school entrance examination..." the dean said.

"What the dean means is that my father...is missing?"

Yun Xinghe was shocked. He knew very well what missing meant. In the dangerous space, losing contact usually meant something might have happened.

"This is not necessarily a child. The maximum communication distance of a quantum communication device is 10 light years. If Chenguang does not put down the relay signal base station in time, if it exceeds 10 light years, even quantum communication cannot maintain signal entanglement... Forgot to throw away This is also possible if we get off the base station.”

Of course, the dean actually has another sentence in his mind: The release program of the relay signal base station on board the Morning Light runs automatically. One is released every 4.9 light-years. It is impossible for the Morning Light to miss two in a row.

The Morning Light is still a top-secret experimental detection spacecraft equipped with an antimatter engine. It is highly advanced. Even if some failures occur due to poor reliability, it is unlikely that such a low-level failure will occur.

So there are only two possibilities left:

1. Danger is indeed encountered.

2. Do it intentionally.

In short, this is a mystery. If you want to solve this mystery, you must either send another manned spacecraft or launch an unmanned probe to the R136A star.

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

There is no other reason. After detection, scientists discovered that the R136A galaxy has a huge water-rich planet, and there are also traces of some intelligent civilizations.

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

"After that, can I go find my father? I think he might 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 study hard and strive to become an excellent captain!"

"Yes! Dean!"

Yun Xinghe gave another straight salute and left the dean's office.
