Shimen City, although Shimen is not a coastal city, but as a large city in the Central Plains, it also suffered a severe blow in the war when the Gaia civilization invaded the earth, and the Shimen City rebuilt after the war has not seen the traces of the war after several years of construction, but unfortunately the scenery and buildings in those memories are no longer there.

A small building, this small building was rebuilt according to the way it was built, in fact, buildings like this were rarely used in post-war reconstruction, for the simple reason that new materials and construction techniques were more suitable for reconstruction work, but this small building is an exception, and the reason why it was built according to its original appearance is because it was the teaching building of Shimen Institute of Technology.

In fact, the teaching staff building was demolished more than 20 years ago, and later Shimen Institute of Technology became Shimen University, and a new building was built on the site of the original teaching staff building. The building was destroyed in the war and left in ruins. Returning to the outside world from the earth base, Wan Changchun stayed in the desert base for a whole year, and after the new era began, Wan Changchun proposed to go back to Shimen to see, this request was of course agreed, and Su Yichen and Wan Yi accompanied Wan Changchun back to Shimen, which had begun to be rebuilt.

Shimen University has become a ruin, and there are few preserved buildings in the past, in fact, even if they are preserved, those buildings are completely different from those in Wan Changchun's memory. Standing on the campus of Shimen University, Wan Changchun set his eyes on the ruins of the teaching building where he once lived, with a complicated and emotional expression.

Not only him, but also Su Yichen and Luo Yan, because they have common memories and incomparable nostalgia here.

After the establishment of the Earth Federation, the global colleges are also being rebuilt, but compared with the previous ones, some adjustments will be made, not only for the overall education aspect, but also because of the needs of the earth reconstruction and planning. What's more, the planet's population is currently declining. Both the faculty and the number of educated students are not as good as before, so some colleges have been merged to restore the foundation of education, while the damaged Shimen City, several institutions of higher learning, including Shimen University, have been merged and rebuilt, and the new school site will also be relocated.

Although the newly established university will still bear the title of Shimen University. But for Wan Changchun, he is no longer familiar with Shimen Institute of Technology. Looking at the ruins of the teaching staff building that had been sorted out, as well as the completely unfamiliar scenes around it, Wan Changchun's heart couldn't say anything.

Originally, both Lin Dong and Tian Lao built a place for Wan Changchun to stay in the Northwest Base, and even in the Federal Academy of Sciences that the Earth Federal Government was preparing to establish later, Wan Changchun also had a place. After all, as a once famous scholar in China, Wan Changchun will inevitably be supported by all Chinese scientists in terms of qualifications and influence, and as long as he wants to, he will have no problem getting a good position in the Federal Academy of Sciences. According to him, after 40 years of separation from society, the knowledge he mastered is completely no longer suitable for this era, and in this case, entering the Federal Academy of Sciences is completely a corpse vegetarian meal, it is better to return to the familiar Shimen to calm down and have a good understanding of modern science, and then do some basic theoretical research, and go to the university as a faculty member to be more suitable for him.

Due to Wan Changchun's insistence. In the end, everyone reluctantly agreed to his decision. And this time when he returns to Shimen, Wan Changchun will not only live in Shimen, but also continue to serve as a professor at Shimen University. Back to the position he knows and likes. But now, everything is wrong, which makes Wan Changchun, who had a vision and expectation for his future life before coming to Shimen, a little disappointed. Seeing his complicated expression, as well as the deep sigh that could not be erased in his eyebrows, Wan Yi couldn't help but mention that he would build a building on the ruins of this ruin according to the architecture of the year.

This construction made Su Yichen and Luo Yan's eyes suddenly light up. That's right! Why didn't they think of it? It didn't work before, but now there is no problem at all, if it is built according to the appearance of the teaching staff building back then, this is not only a great comfort to Wan Changchun, but also to Su Yichen and Luo Yan.

Just do what you say. Su Yichen quickly made a report to the above, and then began to arrange. For the old faculty dormitory building that has been demolished a long time ago, Su Yichen is extremely familiar with it, not to mention the powerful artificial intelligence assistance, which made a simulation model in a short time.

When it was confirmed that there was no difference between the simulation model and the memory, the small building was built in just over a month, and the completed building was exactly the same as it was back then, even the surrounding trees and paths were exactly the same, standing in front of the building, looking at the red building, and the familiar windows, when everyone came to this building, whether it was Wan Changchun, Su Yichen, Luo Yan, and even Lin Dong, who came to the house, they were all immersed in the memories of the year.

Su Yichen and his wife asked for the suite on the right hand side of the first floor, because this was once the home of his mentor Professor Luo Shaohua, the layout and furnishings in the room were exactly the same as back then, walking into the room, as if they had traveled through time and space in an instant, the door of the study seemed to be open at any time, Professor Luo Shaohua wore a cashmee with an open collar and walked out of the study with a smile, with three points of majesty and seven points of love, greeting his favorite disciple .......

"This is the ...... home." Holding his hands together, Su Yichen whispered to Luo Yan, Luo Yan, who had long been full of tears, nodded his head heavily, yes! This is their real home, the home they have been thinking about in their dreams! At this moment, the sourness, memories, sweetness, and warmth in my heart are fused together.

Lin Dong also asked for a house here, just upstairs from Su Yichen and them, and he also learned from Su Yichen and his wife to decorate the room as it was back then. Even Tian Lao had the cheekiness to occupy the suite opposite Su Yichen after coming to see it, and kept saying that he would definitely come back here to retire after he retired.

Of course, whether it is Tian Lao or Lin Dong, even Su Yichen and his wife cannot live here for a long time. Needless to say, after serving as the president of the Federal Academy of Sciences, his work is extremely busy, and it is good to be able to come back and live for a few days every year. Lin Dong is slightly better, although he also serves on the committee of the Federal Academy of Sciences, but for him, he has basically taken a back seat, his body is not the reason, and with the development of technology, his illness has been completely cured. His physical condition is much healthier than back then, coupled with some breakthroughs in biotechnology, although the current earth civilization has not yet been able to reach Pluto's life-sustaining system recovery ability, it is not a problem for Lin Dong's physical condition to live for a few more decades.

The key is that after listening to Wan Changchun's decision, Lin Dong also had the idea of returning to the university to work, but he can't let go of the current work of the Federal Academy of Sciences for the time being. However, Lin Dong has also decided that he will get rid of tedious research in a few years. So as to return to the familiar university and be accompanied by the teacher Wan Changchun, teach and educate people together, and live a relaxed life together.

"Teacher Wan!" Knocking on Wan Changchun's door, Su Yichen and Luo Yan are here to say goodbye to him today, and they will return to the Federal Academy of Sciences tomorrow. Professor Adams's practice has been a success, and for Su Yichen, who has been supporting the project, he must rush back as much as possible.

"Hehe, you have a blessed mouth today, come in quickly, come in quickly. Wait for me in a moment! Wan Changchun, who opened the door, was wearing ordinary home clothes, with an apron tied around his waist, and a shovel for stir-frying, at this time he didn't look like a scientist at all, but clearly an ordinary old man, and an old man who was cooking.

Let Su Yichen and his wife enter the door, Wan Changchun was not polite to them, and directly let them sit in the living room. Then he went headlong into the kitchen. After a while, a tempting aroma came out along with the dish plate that Wan Changchun was carrying. Luo Yan hurriedly went up to help tidy up the table, Su Yichen raised his hand and wanted to take the plate, but was rejected by Wan Changchun, and directly put the plate on the table with his own hands.

"Sweet and sour carp, how is it, my skills are not bad, right?" Wan Changchun smiled proudly. This dish is his specialty, he hasn't made it for a long time, and today he knows that Su Yichen and his wife will come over and prepare it for them.

"It smells so good!" Luo Yan sniffed intoxicatedly, and gave a thumbs up without hesitation: "Uncle Wan, your craftsmanship is gone." I remember trying this dish more than 40 years ago, and I've been trying to make it myself, but the taste is always a little different from yours. ”

"Of course!" Wan Changchun said with a smile: "Actually, cooking and doing it are the same thing, the difference is big, there are tricks, I tell you, to make this fish, one is to choose fish, the second is to raise water, and the third is to ...... when dealing with fish." ”

As soon as it came to this dish, Wan Changchun immediately danced with his eyebrows, and explained it by gesture, Luo Yan listened attentively, and asked a few words when she heard what she didn't understand, Wan Changchun didn't look bored at all, and even happily explained it to her in detail, looking like a good teacher.

Of course, Su Yichen knew why Luo Yan did this, and immediately watched with a smile on the side, and they discussed how to cook a dish as enthusiastically as if they were discussing a topic. It wasn't until he said for a few minutes that Wan Changchun remembered that there were still two dishes in the kitchen that were not served, and slapped his thigh and went into the kitchen again, this time Luo Yan directly followed up to help.

Wan Yi was arranged to other places because of work needs, Wan Changchun is basically living alone now, and there is also a nanny appointed to take care of his life, plus the new Shimen University has officially opened, and Wan Changchun, who has returned to school, lives a very fulfilling life.

Soon the dishes were served, and there was a light tofu soup, although it was a common meal, but the three of them enjoyed the atmosphere, chatting while eating, and the room was full of the warmth of life.

After finishing the meal and making two cups of tea, Luo Yan took the initiative to take over the work of cleaning up the kitchen, and Wan Changchun and Su Yichen sat down in the living room and chatted about their respective work.

first asked Wan Changchun about the situation in the school, Wan Changchun chatted happily, and then took over the topic and asked Su Yichen about the progress of the Federal Academy of Sciences and their arrangements.

"The dark matter has been completed, we will rush back tomorrow, if it is as short as half a year, and as long as a year, the practical dark matter equipment can be officially taken out."

"This is good! This is good! Wan Changchun was very happy and said: "The dark matter weapon is a powerful deterrent weapon, our earth civilization has entered the ranks of cosmic civilization, but for the entire universe, the earthlings are just a newborn baby. In this case, it is extremely necessary to master such a weapon, we earthlings can not invade others like the Gaia, but we must have the ability to protect ourselves, Xiao Su, you are doing a good job! ”

"yes, exactly." Su Yichen nodded slightly, fully agreeing with Wan Changchun's point of view, after entering the cosmic civilization, the earth civilization must have the ability to protect itself, and the technological breakthrough of dark matter ensures this, which is the same as the nuclear weapons of the countries on the earth at the beginning.

"Do you have any plans for the next steps?" Wan Changchun then asked again.

Su Yichen talked about the plan of the Federal Academy of Sciences, but for the entire plan, including the many implementations that are currently underway, Su Yichen is only a guiding role, and there are not many people who are really directly responsible. In addition, Su Yichen has decided that he and Luo Yan will leave the earth in the near future, return to Pluto to make some preparations, and then prepare to leave the solar system to see the real universe.

"Is this in a hurry?" Wan Changchun frowned slightly, it is inevitable for human beings to enter the cosmic civilization and truly step into the universe, and he also understands Su Yichen's intention in doing this, but he feels that he is a little too anxious to arrange it like this.

Su Yichen smiled and said, "Teacher Wan, do you remember the years when you and Lao Hu disappeared at the Earth Base? ”

"High-dimensional technology?" Wan Changchun raised his eyebrows and immediately asked, after saying that, he thought about it, sighed and nodded: "That's right, I know that you have always been particularly interested in this technology, if my guess is correct, you are planning to follow the footsteps of the Rand civilization to find the true mystery of this technology, right?" ”

"Yes, this is a reason, and another reason is that I want to see the universe and contact other alien civilizations, after entering the universe civilization, our earth civilization must contact outward instead of sticking to itself, otherwise the situation of the Gaia civilization will reappear, in fact, I know from the information left by the Rand civilization that the entire galaxy is not as terrible as we imagined, and the order still exists in the universe civilization, only the more contact it is, the more beneficial it is for the future of the earth civilization."

Su Yichen's words moved Wan Changchun, and he nodded in approval, but he still asked Su Yichen to be fully prepared before he could leave, and he had to inform him when he left.

"Don't worry, I'll let you know on the day of departure." Su Yichen smiled and agreed, and then he suddenly remembered something, saying that there was something to give to Wan Changchun, and then took out a stack of things wrapped in paper from the bag he carried and handed it to Wan Changchun, Wan Changchun took it suspiciously and opened it in Su Yichen's smiling and staring gaze, when he saw what was inside, he was stunned at first, and then his hands couldn't help but tremble slightly excitedly.
