"Back then, I didn't go to the library in the university town, and I was reading and thinking quietly in the library, which was almost the best time of those days......." Tang Wei recalled the past, and the corners of his mouth couldn't help showing a smile, although a long time has passed, and in a sense, Tang Wei was at the trough of his career at that time, but now looking back, there is an inexplicable nostalgia in his heart.

Hearing Tang Wei talk about the library, Meng Lin also remembered the time when he met Su Yichen in the library. It was when he met Su Yichen in the library, and with the help of this brother and teacher, Meng Lin gradually grew up from an inconspicuous college student, step by step to today.

"What school did you teach in?" Meng Lin asked casually, there are several schools in the university town, looking at him as a famous astrophysicist, Tang Wei should have been a teacher at a certain university, as for the position, it is estimated that he is a lecturer or even an associate professor, but it is certain that Tang Wei is not famous in the school, otherwise Meng Lin should have heard about it a long time ago, and as far as he knows, Tang Wei is famous in the scientific world or after he went abroad.

"An ordinary school, maybe you haven't heard of it at all." Hearing Meng Lin ask, Tang Wei suddenly laughed.

"Ordinary school?" Meng Lin didn't understand what Tang Wei meant, how could he not know about the several universities in the college town? Is there a college in a college town that you don't know about? Thinking of this, Meng Lin showed a puzzled expression.

Seeing Meng Lin's expression, Tang Wei knew that he had something wrong, and immediately laughed: "I don't teach at a university, I was just an ordinary middle school teacher, and this middle school is not a key school, it is a private international school." ”

"International schools? Secondary school? Who would have thought that Meng Lin was stunned when he heard this. He looked at Tang Wei with a strange expression, and just as Tang Wei subconsciously touched his face and didn't understand why Meng Lin looked at him like this, Meng Lin asked, "You can't be in Yuying International Middle School, right?" ”

"Huh! How do you know? Tang Wei was surprised at this time, and couldn't help but widen his eyes.

"Is it really this school?" Meng Lin didn't expect that he would guess it casually, this is simply too coincidental, Tang Wei and Su Yichen once worked in a school. Are they still colleagues?

"Do you know Mr. Su Yichen?"

"Of course I know, when Xiao Su went to the school to report, he took over my position, and I had a drink with him before I left the country and went abroad...... Tang Wei blurted out, and suddenly reacted halfway through the words: "What? Do you know him too? ”

Meng Lin smiled and nodded again and again, telling Tang Wei that he not only knew Su Yichen, but even his achievements today could not be achieved without Su Yichen's help. It was Su Yichen's selfless guidance and encouragement that an ordinary college student embarked on the road of scientific research little by little.

Not only that, when Su Yichen was teaching at Yuying International Middle School, Meng Lin often went to the school to ask him for advice, and he was particularly familiar with the situation of the school, including Su Yichen's dormitory. And sometimes it's too late, Su Yichen will even arrange to stay overnight, and the place to stay is in an empty dormitory not far from his dormitory.

Asked about the location of this empty dormitory, Tang Wei was immediately happy, and made trouble for a long time, Meng Lin once lived in his previous dormitory. The coincidence of coincidences is a little unbelievable, and the two of them have suddenly become much closer to the topic, and you and I have a happy chat.

"If I hadn't left back then, maybe I would have met you, Xiao Meng."

"Not necessarily. If you don't leave, how can Mr. Su go to the school to take over your job? So, you have to go! Meng Lin deliberately quipped. Tang Weile laughed and nodded, it is true, many things in the world are difficult to say, just a coincidence will lead to what happened later. Just as Meng Lin said, if he hadn't resigned because he had to resign back then, Su Yichen would not have gone to that school. If Su Yichen didn't go to school to take over his position, then he wouldn't know Meng Lin, and if he didn't know Meng Lin, then Meng Lin's future reasoning would probably change.

What's more, when I resigned and went abroad, I finally fulfilled my dream. So that there will be later achievements. Fate is really indescribable, as if there is a pair of invisible hands manipulating all this, which is extremely emotional.

Chatting about the past in his memory, chatting about Su Yichen who they all knew, compared with Meng Lin, although Tang Wei knew Su Yichen earlier, he really knew Su Yichen's achievements after the war. After the war, the alliance was dissolved, the federation was established, and Tang Wei and his scientists entered the Federal Academy of Sciences to work, and then they met Su Yichen again. However, because of the different directions of their respective research, and the fact that Su Yichen's main energy was on the earth base back then, he and Tang Wei only had some work contact, although the two sides had also talked about some other topics, but the conversation was not deep.

As a senior researcher of the Academy of Sciences, and now the president of the branch, Tang Wei slowly learned that it was Su Yichen who laid the foundation for the research direction of the entire Academy of Sciences, and there are even some legends that the war between the Earth Civilization and the Gaia Civilization ended in the victory of the Earth Civilization, and Su Yichen played a great role in it. If it weren't for Su Yichen, maybe the earth civilization would have been enslaved by the Gaia civilization a long time ago.

It's a pity that when he heard about these things, Su Yichen had already left the Federal Academy of Sciences, and even left the earth to go to the unknown universe, which made Tang Wei very emotional.

"It's been almost eight years since Xiao Su left Earth, right?" Calculate the time, Tang Wei asked.

Meng Lin nodded: "Next month will be eight years, and the days will pass really fast, eight years will pass in a blink of an eye." ”

"Yes, eight years, time is so fast!" Tang Wei thought for a while and asked, "Xiao Meng, you work at the Pluto base, and the information sent back by the Vanguard is all accepted and transferred back to Earth through the Pluto base, right?" How is it, have you received any messages from Xiao Su recently? Is he okay now? ”

"The information is received, but you also know that the Pioneer has already flown out of the solar system, and the farther away they are from Earth, the more difficult it is to transmit information, and because of the long distance, the information will inevitably be delayed, to be honest. Now Pluto has received messages from the Vanguard several years ago, and I don't know exactly what happened to them now, Mr. Su, but don't worry, at least when I come back, judging from the content of the messages, they have been going smoothly along the way. ”

"It's good if it's going well, it's good if it's going well!" Tang Wei smiled and nodded, as for the content of the information, he didn't ask. First, some of the content is confidential, and as the president of the Academy of Sciences, he is very aware of this system, even if Meng Lin has left the Pluto base and comes to work in the Academy of Sciences, it is impossible to disclose the content of this information.

Walking to the window, looking up at the blue sky, although he can't see the brilliant galaxy now, Tang Wei's eyes can feel the vastness of the universe through the blue sky and white clouds.

As an astrophysicist, Tang Wei has certainly been to the universe in a spacecraft, not to mention his experience at the moon base. Last year. He presided over a project and took a scientific research spacecraft around the edge of the Oort Nebula, and although the source of the backup data provided by them was not indicated, Tang Wei knew very well in his heart that the information came from the Pioneer if it was not accidental.

That expedition was a huge gain for the Academy of Sciences, and Tang Wei, who personally led the team, was even extremely envious in his heart that Su Yichen could fly out of the solar system and go to the unknown universe to explore. Such a feat is a dream of every scientist who studies astrophysics, and in fact it is not only him. Even Dr. Elena was the same, and even mentioned this in a private correspondence between Dr. Elena and Tang Wei some time ago. Intending to propose to the headquarters of the Academy of Sciences to organize a new space exploration plan in the near future, Tang Wei agreed immediately, and even asked that when the plan was implemented, he would personally lead a team to follow the footsteps of the Pioneer into the depths of the universe to find the infinite mysteries contained in the universe.

Far from Earth, the Pioneer spacecraft continued its voyage for eight years. The Vanguard is now extremely far from Earth, but they are only halfway through their journey, and there is still a long way to go ahead of them.

After leaving the Golden Galaxy, Vanguard passed through six more galaxies of various sizes, one of which was a full five times larger than the solar system. It can be considered a medium-sized galaxy in the Milky Way.

However, none of these galaxies have the existence of life planets, and the galaxy is barren, which shows that life planets are so rare and precious in the entire universe, and the generation of intelligent life is so difficult.

But in addition to the planet without life, in these six galaxies, Su Yichen's harvest is still huge, the universe is indeed a treasure trove of countless wealth, compared with some resources, the golden planet of the Golden Galaxy is not worth mentioning at all, the Pioneer even found a semi-gas planet containing a large number of precious materials in one of the galaxies, if these materials can be collected and utilized, it is enough for the earth civilization to not need to consider the problem of resources in the next tens of thousands of years, its value is much higher than that of the Golden Planet, but the problem is hereDue to the relative proximity of this planet to the "sun", the huge sun and strong gravitational pull make it particularly difficult to mine and collect resources on its planet.

In addition, the Pioneer spacecraft discovered an asteroid made of diamonds while passing through an asteroid belt, and everyone on the Vanguard was stunned when this dazzling asteroid appeared. In fact, according to the current technology, it is no longer a problem to synthesize large diamonds, and if necessary, it is possible to use the equipment on board the Pioneer to synthesize a diamond the size of a baby's fist, but the time and energy required is extremely high.

The concept of diamonds as a luxury store of value no longer exists, and ordinary diamonds have fallen from their high price status to the dust and become a special industrial product. But in any case, it still has at least some value, and coupled with the particularity of diamonds, this kind of sparkling and beautiful is still favored in terms of crafts, and when an asteroid the size of half a moon and all made of diamonds is detected, everyone is still amazed by it.

The diamonds of the asteroid include almost all types found on the earth, those golden yellow, brown, green, and even including pink, red, blue, these rare colored diamonds, there are some special colored diamonds that have never been seen before, such as this purple colored diamond, its color is particularly pure, and then the purple is deep and the fiery red faintly revealed, protecting a burning flame from beating inside the diamond, which is particularly rare.

Now that I have seen it, then I will not miss it, the Pioneer deliberately stayed on the side of this asteroid for a day, and used the robot to collect some diamonds, and this particularly special fire purple diamond was made into a necklace after processing, when Su Yichen gave it to Luo Yan, Luo Yan's relieved and happy smile made him very happy, they have been married for many years, but when they got married, Su Yichen never bought a passable jewelry for Luo Yan, and the two sides only had two very ordinary wedding rings. Now give this one-of-a-kind necklace to your most beloved woman to make up for this regret.

Shortly after leaving the asteroid, the Vanguard spacecraft once again entered the curvature voyage, and when it broke away from the curvature, there was a new small galaxy ahead.

Every time a new galaxy arrives, the first thing Vanguard does is to explore this galaxy, some of this valuable information is transmitted back to Earth through super distances, and the other part will be recorded in the Vanguard's brain, which is an interstellar route in the future. And this time it was the same, Gao Jian skillfully manipulated the instrument, and with the cooperation of Su Li and the spaceship Zhibrain, he scanned and searched the galaxy, but not long after, Gao Jian suddenly exclaimed.

"Communication received!"

"Communications? What's the information? Where did it come from? Su Yichen, who was doing other work, suddenly stopped what he was doing, not only him, Luo Yan and Kevin. Adams also stood up together, his eyes looking towards Gao Jian.

"I don't know, I'm analyzing and cracking, Su Li, help me!" Gao Jian replied hurriedly, Su Li immediately took over his work, and came to a conclusion after dozens of seconds.

"It's not a communication message, it's a call message, it's 51 astronomical units away from us, and its bearing is ......." Su Li clicked on the star map, stretched out her finger on it, and a coordinate position instantly appeared on the star map.

"Call information? What about the content? What is the content? Su Yichen and the others asked hurriedly. (To be continued......)
