Su Yichen and Luo Yan never expected that someone knew them at the Pluto base, and the demeanor shown by the other party was obviously not the kind of politeness and politeness that confirmed their identity. The old general in front of him looked excited as if he had seen a long-lost relative, but looking at the other party's face, Su Yichen couldn't remember where he had seen him for a while.

"...... you?"

Su Yichen couldn't help but ask, and Luo Yan, who was beside him, looked extremely surprised when he heard what the other party said, his eyes were staring at the other party, but he didn't dare to be sure for a while.

"I'm Elc! Brother Su! I'm Elc, remember when I won the table? Teacher Luo...... I'm your student, teacher....... Admiral Elk grabbed the hands of Su Yichen and his wife with tears in his eyes, and his whole body trembled slightly with excitement.

"Sir, you ......." The adjutant had never seen his commander so excited, and although Admiral Elk was in good health, he was already an old man after all, and he couldn't help but step forward to remind him to control his emotions.

"I'm in good health, come on, let me introduce you. This is Mr. Su Yichen, the founder of the Federal Academy of Sciences and the sole authority of the Pluto base. This is Mr. Su's wife, Professor Luo Yan, a well-known artificial intelligence expert and my teacher's ....... ”

"I remember, you're the kid who sold things at Winstage back then." At this moment, Su Yichen finally remembered who Elk was, and Luo Yan beside him recognized this student earlier. Luo Yan also shed tears of excitement and held Elke's hand tightly. The Fenghua boy of that year became an old man in a blink of an eye, time is like an arrow, more than 400 years have passed, Luo Yan never thought that he would be able to meet the student who had long lost contact in this situation.

In her mind, Elk was the handsome, kind, and passionate teenager. And now the vicissitudes of time have carved deep traces on Elke's body, and only a trace of the appearance of the year can be vaguely distinguished between the eyebrows.

"Yes...... It's me! It's me! Admiral Elk nodded repeatedly, the tears on his face were not wiped away, and a bright smile appeared in the blink of an eye.

The old people met each other, this was a scene that both parties did not expect, and it was also a scene that surprised them. The bits and pieces of the past can't help but come to mind. Look at Elk today. Thinking back to the young man back then, I couldn't help but feel a lot of emotion in my heart.

The meeting of the three was joyful, but also with a touch of sadness. When the others heard Admiral Elke's introduction to Su Yichen and his wife, they were first stunned, and then they were taken aback.

If it were in other places, more than 400 years had passed, and many people might not know who Su Yichen and Luo Yan were, but don't forget that this is the Pluto base, and the senior officers who followed Admiral Elk to greet him were all important people in the base.

Who holds the basic authority of the Pluto base. They know it very well. Although the current Earth civilization controls the Pluto base, it is important to know that they have only requested the assistance of the base system through temporary clearance. And there is only one person in the earth civilization who holds the basic authority of the base system, and this person is Su Yichen. Regarding Su Yichen's situation, they also knew that after the earth civilization entered the era of cosmic civilization, the founder of the Federal Academy of Sciences and the great scientist left the solar system for the future of the earth civilization and went to the Blue Star civilization for a friendly visit.

At that time, Su Yichen and the Pioneer spaceship they were riding successfully arrived at the Blue Star Civilization, and because of them, the Earth Civilization and the Blue Star Civilization formed friendly diplomacy. So that the earth civilization that has just entered the universe civilization has an ally in the galaxy.

For the civilization of the earth, or for all the people of the earth. The friendly Blue Star civilization is the most reliable friend of the civilization of the earth. It was precisely because of the help of the Blue Star Civilization that in the second war with the Gaia civilization, the Earth civilization was able to resist the crazy attack of the Gaia civilization, and finally won the war.

Unfortunately, Su Yichen's Vanguard spacecraft encountered an accident when returning to the solar system after completing a diplomatic mission, and his whereabouts are unknown. How many years. Both the Earth civilization and the Blue Star civilization searched for the missing Pioneer spaceship, but still found nothing.

And Luo Yan, an expert in fuzzy mathematics and an expert in artificial intelligence of the earth's civilization, is even more famous, you must know that the brain, which is widely used in the earth's civilization, is more developed than 400 years ago. But the infrastructure is still not separated from the foundation laid by Luo Yan back then. What's more, according to the Blue Star Civilization, an ally of the Earth civilization, Professor Luo Yan also single-handedly created intelligent life, which is a unique way in the entire galaxy to reach such a height at the stage of only a first-level cosmic civilization.

It is precisely because of this reason that Luo Yan is much more famous than Su Yichen among the people, and her name has even been written into the science and education books. In addition, the reason why the Blue Star Civilization was able to break through the civilization stage and enter the ranks of the medium cosmic civilization is also related to Luo Yan according to the Blue Star Civilization, if it wasn't for Luo Yan communicating with the other party's scientists in the Blue Star Civilization back then, then the Blue Star Civilization would not have made a breakthrough in a short period of time, which is not only the side that the Blue Star Civilization is grateful for, but also the proud side of all earthlings.

However, as Su Yichen's wife, a member of the Pioneer spacecraft back then, they disappeared as early as 400 years ago. But now, no one expected that these two people, who had been missing for more than 400 years, would reappear in front of them, and they looked so young, as if the years had left no trace on them, it was simply incredible.

"Teacher, we have never given up looking for your whereabouts since you disappeared with Brother Su back then, but for 100 years...... 200 years ...... 300 years...... Even 400 years have passed, and you have not been found. Where have you been? Why did you come back! "At this time, Admiral Elk was no longer the majestic general, but like a child who had been separated from his mother for many years.

"Silly boy, you are a general now, why are you still like before? Aren't we back? Luo Yan gently held Elke's hand and said softly, in her eyes, Elk is no longer an old man, let alone a general, just like back then, just her own student, a good boy who values affection.

Maybe I feel like I'm a little out of shape. Admiral Elk wiped his face, and smiled again: "You're right, it's good to come back, it's good to come back!" By the way, let's stop standing here and go to my room....... ”

Su Yichen and Luo Yan smiled and nodded. However, they didn't follow Elk right away, now that they had met their acquaintances here, all the problems were no longer a problem, and the Homeland spaceship and their companions couldn't leave them on the ship by themselves.

Immediately, through the equipment of the spacesuit, the internal communication of the Homeland spacecraft was connected, and Gao Jian was told about the situation here. Adams, Sully, and Donle all took a break from the ship. All the crew members of the Vanguard spacecraft were there. Except for Gao Jian, who had seen Elk back then, several of them had never dealt with each other, but everyone was still extremely happy, especially when Tang Le learned that the Blue Star Civilization had personnel stationed in the outer space city of the Pluto base, and even some couldn't wait to meet the long-lost clansmen.

None of this was a problem, and as the supreme commander of the base, Admiral Elk made arrangements immediately. He sent an officer to escort Tang Le to Space City to meet with the personnel stationed in the Blue Star Civilization. As for others, such as Gao Jian and Kevin. Naturally, Adams arranged accommodation. However, for Su Yichen and his wife, Admiral Elk still eagerly invited them to his residence to rest.

"The place is nice. The conditions of our year were much better. Coming to Admiral Elke's residence, Su Yichen nodded and exclaimed. However, he still thought about the cabin he built with Luo Yan, including Su Li, in the internal ecosystem of the Pluto base, but whether the cabin was still there.

"The house is still there, but if you want to live in it, you have to tidy it up, and that place has been listed as a heritage building." Unexpectedly. Elk gave them one such answer. It turned out that decades after Su Yichen and their disappearance, the cabin they once lived in was listed as a special civilization building to commemorate their contribution to the earth's civilization and mankind, so as to protect it. Although the cabin is still there, it is no longer suitable for living for this reason, and if Su Yichen and his wife want to live in it, they must redecorate it.

This answer surprised Su Yichen a little. They never imagined that their residence would become a civilized building. But think about it, more than 400 years of time, such a long time, coupled with the special significance of this small cabin, it is understandable that later people arranged it this way.

Sitting down in the living room, Admiral Elk asked the lieutenant to make a pot of milk tea for the guests. Whether it is Su Yichen or Luo Yan, they often drank this kind of milk tea when they were in the northwest. Drinking sweet milk tea, it is as if you have traveled through the years and returned to the distant moment in the depths of your memory.

Admiral Elk was very concerned about the disappearance of Su Yichen and his wife, and after taking a sip of tea, he couldn't wait to ask about the accident and the subsequent scene.

Elk is not an outsider, not to mention Su Yichen, who has returned here, they are going to report their experience to the current high-level of Earth civilization, and Elke is now an important member of the army, whether it is public or private, he is qualified to know this.

Immediately, Su Yichen began to tell their experience, starting from the loss of control of the Pioneer spacecraft on the return trip, and then falling into an accidental wormhole, and gradually talking about when they came out of the other side of the wormhole, and when they confirmed their location, they actually found that they had come to the ...... of the Andromeda Galaxy.

Extragalactic galaxies, the Galen civilization, the ruins of the Rand civilization, the strange primitive planet, the man who died inexplicably...... These came out of the mouths of Su Yichen and Luo Yan one by one, although Elk was a veteran of a hundred battles, he was still stunned by such a large amount of information and an unbelievable situation. If it weren't for the fact that the people who said this were Su Yichen and his wife, Admiral Elk would even think that this was neurotic nonsense.

"You...... You guys...... Really went to the Andromeda galaxy? Until the end, Admiral Elk was still a little skeptical.

"Of course, if we hadn't met Galen in the Galen civilization and got a Rand civilization spaceship, we wouldn't have been able to come back. Don't you believe that such a big spaceship is parked at the airport? Seeing his expression so shocked, Su Yichen couldn't help but smile and asked.

"No, no, of course I do, but it's too bizarre this time." Admiral Elk, who sensed that he had said the wrong thing, laughed embarrassedly, and even raised his hand and scratched his head like a child.

After talking about their experience, and then chatted about other things, Su Yichen couldn't help but ask about Elke's situation, Elke immediately told Su Yichen and his wife about his experience of participating in the organization of resisting Gaia civilization and then joining the army, in the past 400 years, Elke has been serving in the army, and because of the meritorious service in the second war between the earth civilization and the Gaia civilization, he gradually became a famous general.

"I'm sorry teacher, you always wanted me to learn math back then, but then I became a soldier ......."

"What are you talking about, after all, the path of life depends on your own choice, and you have a successful career now, and even become a general, it's too late for me to be happy to be a teacher with a student like you." Luo Yan said happily, and then asked about the situation of the other students, but Elk shook his head gloomily and told Luo Yan that because of the Gaia civilization invasion of the earth, only he was lucky to survive, and the others, including their villages, were destroyed in the war.

The laughter in the room suddenly stopped, and the atmosphere became solidified. Luo Yan's eyes couldn't help but flash with tears, and she even blamed herself for why she didn't go back to the northwest to see it earlier after the war, but it took so many years to learn about such a thing.

"Teacher, don't be sad, after so many years, in fact, we are very lucky to see each other now."

"yes!" Both Su Yichen and Luo Yan nodded with a long sigh.

Then, they inquired about the whereabouts of some old friends, such as Wan Changchun, Lin Dong, Tian Lao, Hu Zhijun, and Li Xiao...... Wait, but what disappointed them is that these old people are long gone, Professor Wan Changchun died after the victory of the second war between the Earth civilization and the Gaia civilization, although he could prolong his life through hibernation and other means at that time, but was rejected by Professor Wan Changchun, in his words, he was able to see the Earth civilization become a cosmic civilization, and even won such a war, and there are no regrets in life. Life is from beginning to end, there is no eternal life, death and birth are the same, these are the two most important points in a person's life, there is no point in prolonging life is disrespectful to life, and he is already very old, it is better to let everything fall naturally.

Soon after Professor Wan Changchun's death, Lin Dong and Tian Lao also died one after another, then Hu Zhijun, Li Xiao died unexpectedly a hundred years later due to an experiment, and others also passed away in the 400 years.

Unexpectedly, the old friends were no longer there, recalling those familiar faces, Su Yichen and Luo Yan felt very uncomfortable. And at this time, Elk finally told the good news, he told them that there was still one person alive.

"Who's still there?" Su Yichen and his wife hurriedly asked.

"Marshal Hu, Marshal Hu Gang!" (To be continued......)
