"I went to the library in the university town a lot back then, and quietly read books and think about problems in the library. It was almost the best time for those days... △" Tang Wei recalled the past, and couldn't help but smile. Although that period had passed for a long time, and in a sense, Tang Wei was at the trough of his career at that time, when he looked back, he felt an inexplicable nostalgia in his heart.

When he heard 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 that he had met Su Yichen. With the help of this brother and teacher, Meng Lin gradually grew up from an inconspicuous college student and got to this day step by step.

"Which school did you teach at that time?" Meng Lin asked casually. There were several schools in the university town. He was watching him as a famous astronomical physicist. Tang Wei should have been a teacher at a certain university. As for the position, he probably was a lecturer or even an associate professor. But it is certain that Tang Wei was not famous in the school, otherwise Meng Lin would have heard of it for a long time. And as far as he knew, Tang Wei was famous in the scientific community or after going abroad.

"You may have never heard of an ordinary school." Tang Wei laughed when he heard Meng Lin's question.

"A normal school?" Meng Lin was a little confused about what Tang Wei said. How could he not know several universities in the university town? Is there any college in the university town that he doesn't understand? Thinking of this, Meng Lin showed a puzzled expression.

Seeing Meng Lin's expression, Tang Wei knew that he had misunderstood and immediately laughed: "I don't teach in college. I was just an ordinary middle school teacher at the time, and this middle school was not a key school, it was a private international school."

"International school? Middle school?" Who would have thought that Meng Lin was stunned when he heard this. He looked at Tang Wei with a strange expression. Just as Tang Wei subconsciously touched his face and didn't understand why Meng Lin looked at him like this. Meng Lin asked, "You are not at Yuying International Middle School, are you?"

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

"It's really this school?" Meng Lin didn't expect that he could guess it just by guessing it. This was a coincidence. Tang Wei and Su Yichen used to work in the same school. Are they still colleagues?

"Do you know Mr. Su Yichen and Mr. Su?"

"Of course I know each other. When Xiao Su went to school to report, he took over my position. Before I left China and went abroad, I had a drink with him..." Tang Wei blurted out, and suddenly reacted after he was halfway through his words: "What? Do you know him too?"

Meng Lin nodded repeatedly with a smile and told Tang Wei that he not only knew Su Yichen, but even his achievements today were inseparable from Su Yichen's help. It was Su Yichen's selfless guidance and encouragement that an ordinary college student had gradually embarked on the road of scientific research.

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. He was particularly familiar with the school situation, including Su Yichen's dormitory. And sometimes it was too late, Su Yichen even arranged to stay, and the place to live was in an empty dormitory not far from his dormitory.

After asking about the location of this empty dormitory, Tang Wei was immediately happy. After a long time of fuss, Meng Lin had lived in his former dormitory. The coincidence among the coincidence was simply unbelievable. The two of them followed the topic and immediately got closer, and they chatted happily with each word.

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

"This is not necessarily. If you don't leave, how could Mr. Su go to the school to take over your job? So, you have to leave!" Meng Lin joked deliberately. Tang Wei laughed happily and nodded repeatedly. It is true. Many things in the world are hard to say. Just a coincidence will lead to what happened later. Just as Meng Lin said, if he hadn't resigned, Su Yichen wouldn't have gone to that school. If Su Yichen didn't go to the school to take over his position, then he would not know Meng Lin. If he didn't know Meng Lin, then Meng Lin's future principles would probably change.

More importantly, I resigned and went abroad to realize my dreams. This is why I achieved my future achievements. Destiny is really indescribable, just like an invisible hand that controls all this, which makes me feel extremely touching.

Talk about the past in my memory and the Su Yichen they all knew. Compared with Meng Lin, although Tang Wei knew Su Yichen earlier, he really knew Su Yichen's achievements were after the war. After the war, the alliance was disbanded and the Federation was established. Scientists such as Tang Wei and others entered the Federal Academy of Sciences to work, and then they met Su Yichen again. However, because of their different research directions, and Su Yichen's main energy was on the Earth base at that time, and only had some work contact with Tang Wei. Although the two sides had talked about other topics, they did not have a deep conversation.

Tang Wei only learned about Su Yichen's situation a little later. He never expected that Su Yichen, who was patted on his shoulder and called "little brother", was actually the "soul" of the Federal Academy of Sciences. As a senior researcher of the Academy of Sciences and the current director of the branch, Tang Wei gradually realized over the years that it was Su Yichen who laid the foundation for the research direction of the entire Academy of Sciences. There are even some legends that the war between the Earth Civilization and the Gaia civilization ended with the victory of the Earth Civilization. Su Yichen played a great role in it. If it weren't for Su Yichen, the Earth Civilization might have been enslaved by the Gaia civilization.

Unfortunately, when he heard about these things, Su Yichen had left the Federal Academy of Sciences and even left the earth to go to the unknown universe, which made Tang Wei very moved.

"Xiao Su has been leaving the earth for almost eight years, right?" Tang Wei asked.

Meng Lin nodded: "Next month will be eight years. Life is really fast, and eight years have passed 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 Pluto Base. The information sent by Pioneer is accepted by the Pluto Base and is it transferred back to Earth through Pluto Base? How about it? Have you received Xiao Su's message recently? Is he okay now?"

"The information was received, but you also know that the Pioneer had already flew out of the solar system. The farther they were from the earth, the more difficult it was to transmit information. Moreover, because the distance was too long, the information was inevitably delayed. To be honest, the information received by Pluto is sent back from Pioneer several years ago. Now I am not very clear about what Mr. Su and the others are doing, but don't worry, at least when I came back, they were very smooth all the way from the information content."

"It's good if it's good if it's good if it's good if it's good!" Tang Wei nodded with a smile. He did not ask about the content of the information. First of all, some content is kept confidential. As the president of the branch of the Academy of Sciences, he is very clear about this system. Even if Meng Lin left the Pluto base and came to work at 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 I can’t see the brilliant galaxy now, Tang Wei’s eyes could feel the vastness of the universe through the blue sky and the white clouds.

As an astronomer, Tang Wei of course also traveled to the universe on a spaceship, not to mention his experience at the lunar base. Last year, he presided over a project and took a scientific research and exploration spacecraft to circle around the edge of the Alt Nebula. Although the source of the backup information they inspected was not specified, Tang Wei knew very well that if it was not surprising, the information came from the Pioneer.

That investigation has gained a lot for the Academy of Sciences, and Tang Wei, who was personally leading the team, even envied Su Yichen for being able to fly out of the solar system and go to the unknown universe for exploration. Such a feat is dreamt of every scientist who studies astrophysics, and it is not just him. Even Dr. Yilena was the same. It was even mentioned in his private communication between Dr. Yilena and Tang Wei a while ago. He planned to propose to the headquarters of the Academy of Sciences to organize a new universe exploration plan. Tang Wei agreed immediately, and even asked that when the plan was implemented, he would personally lead a team and follow the Pioneer's footsteps to search for the infinite mysteries contained in the universe.

The Pioneer spacecraft continues its voyage in eight years. The Pioneer is now extremely far away from the Earth, but their journey is only halfway through, and there is still many roads ahead of them.

After leaving the Venus galaxy, Pioneer passed six galaxies of different sizes along the way, one of which was five times larger than the solar system. It can be regarded as a medium galaxy in the Milky Way.

However, none of these galaxies exists as a life planet, and there is a barren galaxy. From this point, we can see that the life planet is so rare and precious in the entire universe, and the emergence of intelligent life is so difficult.

But in addition to the lifeless planet, Su Yichen and his friends still gained huge among these six galaxies. The universe is indeed a treasure house of countless wealth. Compared with some resources, the Golden Planet of the Venerable Galaxy is not worth mentioning at all. Pioneer even discovered 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 will be enough to make the Earth civilization not need to consider resource issues in the next tens of thousands of years. Its value is much higher than that of the Golden Planet. But the problem is here. Because this planet is closer to the "sun", the huge sun and powerful gravity make it particularly difficult to mine and collect resources on its planet. According to the difficulty of mining and the consumption ratio, it is a pity.

In addition, when the Pioneer spacecraft crossed asteroid belt, it also discovered an asteroid made of diamonds. When this dazzling asteroid appeared, everyone on the Pioneer was stunned. In fact, according to current technology, synthesizing large diamonds is no longer a problem. If necessary, it can be done using the equipment on the Pioneer to synthesize a diamond the size of a baby fist, but the time and energy required are extremely costly.

Diamonds, as a luxury product, no longer exist. Ordinary diamonds have fallen from their high price status and become a special industrial product. But no matter what, they have at least some value. In addition, with the special nature of diamonds, this kind of shining and beautiful still has many favors in handicrafts. When an asteroid with half a moon size and all diamond structures is detected, everyone is still shocked by it.

The diamonds of asteroids almost include all kinds of rare colored diamonds found on Earth, including golden, brown, green, and even pink, red, and blue. There are also some colored diamonds that have never been seen before. For example, this purple colored diamond is particularly pure in color. When the purple color is dark, the fiery red faintly reveals it. It is particularly rare to protect a ball of burning flames from jumping inside the diamond.

Since I saw it, I would not miss it. The Pioneer stayed on the side of this asteroid for a day and collected some diamonds with a robot. This particularly special fire purple diamond was processed and made into a necklace. When Su Yichen gave it to Luo Yan, Luo Yan's gratitude and happy smile made him very happy. They had been married for many years, but when they got married, Su Yichen had never bought a decent jewelry for Luo Yan. There were only two very ordinary wedding rings on both sides. Now I give this unique necklace to my beloved woman to make up for this regret.

Shortly after leaving this asteroid, the Pioneer spacecraft entered the curvature navigation again. After it broke out from the curvature, another new small galaxy was already ahead.

Whenever a new galaxy is reached, the first thing Pioneer has to do is to explore the galaxy. Some of these valuable information is transmitted back to the earth through excessive distances, and the other part will be registered in the Pioneer's intelligent brain. This future is an interstellar route. This time, Gao Jian skillfully operates the instruments and scans and searches the galaxies with the cooperation of Su Li and the spacecraft intelligent brain. But not long after, Gao Jian suddenly exclaimed.

“Receive communication information!”

"Communication information? What information? Where did it come from?" Su Yichen, who was doing other work, immediately stopped what was in his hand. Not only him, but Luo Yan and Kevin Adams also stood up together and looked at Gao Jian.

"I don't know, I'm analyzing and cracking it. Su Li, help me!" Gao Jian replied urgently. Su Li immediately took over his work and came to the conclusion a few dozen seconds later.

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