Su Yichen and Luo Yan never expected that someone knew them at Pluto Base, and the expressions expressed by the other party were obviously not the kind of politeness and politeness of confirming their identity. The old general in front of him looked as if he had seen a relative who had been away for a long time, but looking at the other party's face, Su Yichen couldn't remember where he had seen him.

"you……?"

Su Yichen couldn't help asking, and Luo Yan beside him looked extremely surprised when she heard what the other person said, staring at the other person with her eyes, but she was not sure for a moment.

"I am Elk! Brother Su! I am Elk. Do you remember when I won Taiwan? Teacher Luo... I am your student, teacher..." General Elk grabbed Su Yichen and his wife's hands in tears, and was trembling slightly excitedly.

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

"I am in good health. Come on, let me introduce it to you. This is the founder of the Federal Academy of Sciences and the only authority of the Pluto Base. This is Mr. Su Yichen, Mr. Su's wife, Professor Luo Yan, a famous artificial intelligence expert, and my teacher..."

"I remember, you are the kid who sold things at Win Taiwan back then." At this moment, Su Yichen finally remembered who Elk was. As for Luo Yan beside him, he recognized the student earlier. Luo Yan also shed tears excitedly and held Elk's hand tightly. The Fenghua boy back then became an old man in a blink of an eye. Time flies, and more than 400 years have passed. Luo Yan never thought that he could still see a student who had long lost contact under such circumstances.

In her mind, Elk was the handsome, kind and enthusiastic boy. Now the vicissitudes of time have left deep traces on Elk's body, and only the eyebrows and eyes can vaguely tell the look of the past.

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

When old friends meet, this is a scene that both parties never expected, and it is also a scene that surprised them. The little bits of past events can't help but surge into my heart. Looking at Elk now, I think back to the boy back then, I can't help but feel a lot of emotion.

The meeting of the three was joyful, and also a hint of sadness. When the others heard General Elk's introduction to Su Yichen and his wife, they were stunned at first, and then shocked.

If it was elsewhere, more than 400 years have passed, many people may not know who Su Yichen and Luo Yan are, but don’t forget that this is the Pluto base. The senior officers who followed General Elk to greet them are all important figures in the base.

Who controls the basic authority of the Pluto base? They are very clear. Although the Earth civilization today controls the Pluto base, we must know that they have always requested assistance from the base system through temporary authority. The only person on Earth civilization has the basic authority of the base system, and this person is Su Yichen. They have also learned about Su Yichen's situation. After the Earth civilization entered the era of cosmic civilization, the founder of the Federal Academy of Sciences, the great scientist, left the solar system for the future of the Earth civilization and went to the Blue Star civilization for friendly visits.

At that time, Su Yichen and the Pioneer spacecraft they were riding successfully arrived at the Blue Star civilization, and for their reasons, the Earth civilization formed a friendly diplomacy with the Blue Star civilization, which had just entered the universe civilization, which had an ally in the Milky Way.

For the Earth civilization, or all Earthlings, the friendly Blue Star civilization is the most reliable friend of the Earth civilization. It is precisely because of the help of the Blue Star civilization that the Earth civilization can resist the crazy attack of the Gaia civilization in the second war with the Gaia civilization, and thus finally won the war.

Unfortunately, Su Yichen's Pioneer spacecraft encountered an accident when he completed his diplomatic mission and returned to the solar system, and his whereabouts were unknown. For many years, both the Earth civilization and the Blue Star civilization have searched the missing Pioneer spacecraft, but they still found nothing.

Luo Yan, this fuzzy mathematics expert and an artificial intelligence expert in the Earth civilization, is even more famous. You should know that although the intelligent brain, which is widely used in the Earth civilization, is more developed than 400 years ago, the infrastructure is still not separated from the foundation laid by Luo Yan back then. Moreover, according to the ally of the Earth civilization, Blue Star Civilization, Professor Luo Yan has also created intelligent life, which is a unique way in the entire Milky Way to reach such a height at the stage of just a first-level cosmic civilization.

It is precisely because of this reason that Luo Yan is much more famous among the people than Su Yichen, and her name has even been written into science and teaching. In addition, the reason why the Blue Star civilization can break through the civilization stage and enter the ranks of medium-universe civilization is also related to Luo Yan. If Luo Yan had not communicated with the other party's scientists in the Blue Star civilization back then, the Blue Star civilization would not have made a breakthrough in a short period of time. This is not only the grateful side of the Blue Star civilization, but also the proud side of all people on earth.

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

"Teacher, after you and Brother Su disappeared, we never gave up looking for your whereabouts, but 100 years...200 years...300 years...even 400 years, we have never found you. Where have you been? Why did you come back!" At this time, General Elk was no longer the majestic general, but like a child who had been separated from his mother for many years.

"Silly kid, you are all generals now, why are you still like before? Aren't we back?" Luo Yan gently held Elk's hand and said softly. In her eyes, Elk is no longer an old man, nor a general. Just like back then, she was just her own student, a good child who values ​​affection.

Maybe I felt a little out of control. Admiral Elke wiped his face and Zhan Yan smiled again: "You are right, just come back, just come back! By the way, let's stop standing here, go to my room..."

Su Yichen and Luo Yan nodded with a smile. However, they did not follow Elk immediately. Since they met acquaintances here, all the problems were no longer problems. The Home spacecraft and their companions could not leave them on the spacecraft and leave by themselves.

Immediately, the internal communication of the Home spacecraft was connected through the space suit equipment, and told Gao Jian and the others about the situation here. After a while, Gao Jian, Kevin Adams, Su Li and Tang Le took a look at the spacecraft. All the crew members of the Pioneer spacecraft were all here. Except for Gao Jian who had seen Elke, no one else had dealt with, but everyone was still extremely happy, especially when Tang Le learned that the Blue Star Civilization had resident personnel in the outer space city of Pluto Base, and he couldn't wait to meet the tribe members who had been away for a long time.

These are not any problems. As the highest commander of the base, General Elk made an arrangement immediately. He sent an officer to escort Tangle to Space City to meet with Blue Star Civilized resident personnel. As for the others, such as Gao Jian and Kevin Adams, they naturally arranged their residence. However, for Su Yichen and his wife, General Elk still eagerly invited them to their residence to rest.

"This place is good. It's much better for us back then." When he came to Admiral Elk's residence, Su Yichen nodded and exclaimed. However, he still thought about the small wooden house he built with Luo Yan, including Su Li in the internal ecosystem of the Pluto base, but whether the small wooden house was still there.

"The house is still there, but if you want to live in someone, you have to sort it out. The place has been listed as a cultural relic building." Unexpectedly, Elk gave them such an answer. It turned out that decades after Su Yichen and his friends disappeared, the small wooden house they had lived in was listed as a special civilized building to commemorate their contribution to the earth's civilization and mankind, and thus protected. Although the small wooden house is still there, it is no longer suitable for living. If Su Yichen and his wife want to live in, they must be redecorated.

This answer surprised Su Yichen a little. They never thought that their residence had become a civilized building for protection. But thinking about it is true that for more than 400 years, such a long time, coupled with the special significance of this small wooden house, it is understandable that people later made arrangements like this.

Sitting down in the living room, General Elk asked the adjutant to cook a pot of milk tea to serve guests. Whether it was Su Yichen or Luo Yan, they often drank such milk tea when they were in the northwest. Drinking sweet milk tea seemed to have passed through the years and returned to the distant moment in the depths of their memory.

General Elk was very concerned about the disappearance of Su Yichen and his wife. After taking a sip of tea, they couldn't wait to ask about the accident that year and the subsequent scenes.

Elk is not an outsider, and Su Yichen and the others who have returned here have to report their experiences to the current top leaders of the Earth civilization. Moreover, Elk is now an important member of the army. Whether in public or private, he is qualified to understand these things.

Immediately, Su Yichen began to tell their experiences, starting from the return trip that the Pioneer spacecraft lost control and then fell into an unexpected wormhole. He gradually talked about the fact that when they came out of the other end of the wormhole and when they confirmed their location, they actually found that they had arrived in the Andromeda system...

The extra-river galaxy, the Galen civilization, the remains of the Rand civilization, the strange original planet, the inexplicable dead person... These are all revealed from Su Yichen and Luo Yan. Although Elk is a veteran who has experienced many battles, he is still shocked by such a large amount of information. If it weren't for the fact that these people were Su Yichen and his wife, General Elk even thought this was a crazy nonsense.

"You...you...really went to the Andromeda System?" Until the end, Admiral Elk was still a little skeptical.

"Of course, if we hadn't met Garen in the Garen civilization and got a Rand civilization spacecraft, we wouldn't have come back. Such a large spacecraft is docked in the airport, don't you believe it?" Seeing his expression so shocked, Su Yichen couldn't help but ask with a smile.

"No, of course I believe it, but this moment is too bizarre." General Elk, who felt that he said the wrong thing, smiled embarrassedly, and even raised his hand and scratched his head like a child back then.

After talking about their experiences, they talked about other things. Su Yichen and the others couldn't help asking about Elk's situation. Elk immediately told Su Yichen and his wife about his experience of joining the organization that resisted the Gaia civilization and then joining the army. During these 400 years, Elk has been in the army, and because of his contributions to the Second War between Earth Civilization and Gaia Civilization, he gradually became a famous general.

"Sorry teacher, you always wanted me to learn mathematics back then, but later I became a soldier..."

"What stupid things are you saying? After all, the path of life depends on your own choice. Moreover, you are successful in your career now, and you have even become a general. I am not 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 sadly and told Luo Yan that he was the only one of his friends who survived because of the Gaia civilization invaded the earth, and the others, including their village, were destroyed in the war.

The laughter and joy in the room suddenly stopped and the atmosphere became solidified. Tears flashed in Luo Yan's eyes. She even blamed herself for not returning to the northwest to take a look earlier after the war. This happened so many years later.

"Teacher, don't be sad. So many years have passed. In fact, it is a great blessing to see us again now."

"Yes!" Both Su Yichen and Luo Yan sighed and nodded.

Then, they inquired about the whereabouts of some old friends, such as Wan Changchun, Lin Dong, Tian Lao, Hu Zhijun, Li Xiao... etc. But what disappointed them was that these old friends were no longer there. Professor Wan Changchun died after the victory of the Second War between Earth Civilization and Gaia Civilization. Although he could prolong his life through hibernation and other means at that time, he was rejected by Professor Wan Changchun. In his words, he could see that Earth Civilization became a cosmic civilization and even won such a war. Life has no regrets. Life is from beginning to end, and there is no eternal life. Death is the same as birth. These are the two most important points in a person's life. It is meaningless to prolong life instead of disrespect for life. Moreover, he is already very old, so it is better to let everything come naturally.

Shortly after Professor Wan Changchun's death, Lin Dong and old Tian also passed away one after another, followed by Hu Zhijun and Li Xiao died a hundred years later due to an experiment. As for the others, they also passed away in these 400 years.

Unexpectedly, all the old friends were gone. Recalling those familiar faces, Su Yichen and Luo Yan felt very uncomfortable. At this time, Elk finally told them that there was another person alive.

"Who is still here?" Su Yichen and his wife asked hurriedly.
