Shimen City, although Shimen is not a coastal city, as a big city in the Central Plains, also suffered a severe blow in the war when the Gaia civilization invaded the earth. After several years of construction, there were no traces of war. Unfortunately, the scenery and buildings in memory no longer exist.

A small building, this small building was rebuilt in the previous appearance. In fact, such buildings were rarely used in post-war reconstruction. The reason is very simple. New materials and construction technologies are more suitable for reconstruction work. However, this small building is an exception. The reason was built in the original appearance is because it was the teaching and work building of Shimen Science and Technology back then.

The teaching and work building was actually demolished more than 20 years ago. Later, Shimen Science and Technology became Shimen University, and a new building was built at the original teaching and work building. The building was destroyed in the war and turned into ruins. Returning from the Earth Base, Wan Changchun stayed in the desert base for a whole year. After the new era began, Wan Changchun proposed to go back to the Shimen to take a look. Of course, this request was agreed, and Su Yichen and Wan Yi accompanied Wan Changchun to return to the Shimen that had begun to be rebuilt.

Shimen University has become a ruin, and the buildings in the past have almost not been preserved much. 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 turned his attention to the ruins of the teaching staff building where he once lived, with a complex expression and emotion.

Not only him, but also Su Yichen and Luo Yan, because they have common memories and extremely nostalgic feelings here.

After the founding of the Earth Federation, colleges around the world are also rebuilt one after another, but compared with the previous ones, the rebuilt colleges will make some adjustments, which not only considers the overall education aspect, but also is also due to the needs of earth reconstruction and planning. More importantly, the population on earth has dropped sharply. Both the faculty and the number of educated people are not as good as before. For this reason, some colleges have been merged to restore the educational foundation as soon as possible. However, the severely damaged Shimen City, including Shimen University, merged and rebuilt, and the new campus will also be re-selected and built.

Although the newly established university still has the title of Shimen University, this is no longer the Shimen Science and Technology he is familiar with. Looking at the ruins of the already organized teaching and work building and the completely unfamiliar surroundings, Wan Changchun couldn't say anything in his heart.

Originally, both Lin Dong and Mr. Tian suggested that Wan Changchun stay in the Northwest base, and even Wan Changchun had a place in the Federal Academy of Sciences prepared to establish later by the Federal Government of Earth. After all, as a once famous scholar in China, Wan Changchun would inevitably receive support from all Chinese scientists in terms of qualifications and influence. As long as he wanted, there was no problem to obtain a good position in the Federal Academy of Sciences. But in the end, this suggestion was rejected by Wan Changchun. According to him, after 40 years of being separated from society, the knowledge he mastered was no longer adapted to this era. In this case, it would be better to go back to the familiar Shimen to calm down and learn about modern science well, and then do some basic theoretical research. It would be more appropriate for him to work as a teaching position in a university.

Due to Wan Changchun's persistence, everyone finally agreed to his decision. And this time when he returned to Shimen, Wan Changchun would not only live in Shimen, but also continue to serve as a professor at Shimen University. Back to his familiar and favorite position. But now, everything is wrong, which makes Wan Changchun, who had longing and expectation for his future life before coming to Shimen, was a little disappointed. Seeing his complex expression and the sigh that could not be eliminated in his eyes, Wan Yi couldn't help but make a suggestion, suggesting that he would rebuild the ruins on this ruined site according to the buildings of that year.

This suggestion made Su Yichen and Luo Yan's eyes lit up. Yes! Why didn't they think of this method? It didn't work before, but now there is no problem at all. If it were restored to build according to the appearance of the teaching and work building back then, it would not only give Wan Changchun great comfort, but also for Su Yichen and Luo Yan.

Do it as soon as possible. Su Yichen quickly reported to the above and then started to arrange it. Su Yichen and the others were extremely familiar with the old teacher dormitory building that had been demolished long ago, not to mention that with powerful artificial intelligence assistance, they made a simulation model in a very short time.

After confirming that there was no difference between the simulation model and the memory, the building was completed in just over a month. The built building was exactly the same as it was back then. Even the surrounding trees and paths were not bad. Standing in front of the building, looking at the red building and the familiar windows, when everyone came in front of this building, whether it was Wan Changchun, Su Yichen, Luo Yan, and even Lin Dong who came here specially, they were immersed in the memories of the year.

Su Yichen and his wife wanted the room on the right side of the first floor, because it was once the home of his mentor Professor Luo Shaohua. The layout and decoration in the room were exactly the same as before. When they walked into the room, they seemed to have traveled through time and space in an instant. The door of the study seemed to be open at any time. The mentor Professor Luo Shaohua walked out of the study with a smile, with three points of majesty and seven points of kindness, greeting his favorite disciples...

"This is home..." Holding hands together, Su Yichen said to Luo Yan softly. Luo Yan, who had been full of tears, focused her head. Yes! This is their real home, the home they have always cared about in their dreams! At this moment, the sorrow, memories, sweetness and warmth in their hearts merged together.

Lin Dong also asked for a house here, right upstairs of Su Yichen and his wife. He also imitated Su Yichen and his wife to arrange the room the same as they did back then. Even after seeing it, Mr. Tian took the house opposite Su Yichen and his wife with shame, and he kept saying that he would definitely return here to retire and retire. Then everyone would visit each other on weekdays and take a walk under the shade of the trees. What a happy and anticipated day!

Of course, it is impossible for Mr. Tian or Lin Dong, even Su Yichen and his wife to live here for a long time. Needless to say, Mr. Tian was extremely busy after serving as the president of the Federal Academy of Sciences. It is good to be able to come back and stay for a few days a year. Lin Dong is a little better. Although he also serves on the Federal Academy of Sciences, he has basically retreated to the second line. His body is not the cause. With the development of technology, his illness has been completely cured. His physical condition is much healthier than that in those days. In addition to some breakthroughs in biotechnology, although the current earth civilization cannot achieve the recovery ability of Pluto's life system, it is not a problem for Lin Dong to live for decades.

The key point is that after listening to Wan Changchun's decision, Lin Dong also thought of returning to university to work, but he could not let go of the current work of the Federal Academy of Sciences for the time being. However, Lin Dong had also decided that he would get rid of the tedious research in a few years. He would return to his familiar university and his teacher Wan Changchun to accompany him, teach and educate people together, and live a relaxed and relaxed life together.

"Teacher Wan!" Knocking on Wan Changchun's door, Su Yichen and Luo Yan came to say goodbye to him today, and they will return to the Federal Academy of Sciences tomorrow, because they just received the news that Professor Kevin Adams's experiment has been successful, and for Su Yichen, who has always supported this project, he must rush back as soon as possible.

"Haha, you have a good time today. Come in and come in quickly. Wait for me a while!" Wan Changchun, who opened the door, was wearing an ordinary home clothes, an apron around his waist, and a shovel for cooking. At this time, he didn't look like a scientist at all, but was clearly an ordinary old man insulated, and an old man who was cooking.

When Su Yichen and his wife were asked to enter the door, Wan Changchun was not polite to them and asked them to sit in the living room. Then he went into the kitchen. After a while, a tempting aroma came out with the dish plates that Wan Changchun was holding. Luo Yan hurriedly came to help organize the table. Su Yichen raised his hand to take the dish plate, but Wan Changchun refused and directly placed it on the table.

"Sweet and sour carp, how about it? My skills are pretty good, right?" Wan Changchun said with a smug smile. This dish is his specialty and hasn't been made for a long time. Today he knew that Su Yichen and his wife would come here to prepare it specifically for them.

"It smells so good!" Luo Yan sniffed intoxication and gave a thumbs up without hesitation: "Uncle Wan, your skills are gone. I remember trying this dish more than 40 years ago. Later, I have been trying to make it myself, but the taste it makes is a little different from yours."

"Of course!" Wan Changchun smiled and said, "In fact, cooking is the same principle as doing experiments. The difference is huge if you have a slight difference. If you have a little trick, I will tell you that you need to choose fish, second, water, and third, when dealing with fish, you must..."

As soon as she talked about this dish, Wan Changchun immediately danced and gestured to explain. Luo Yan listened attentively, and asked a few questions when she didn't understand. Wan Changchun looked unhappy at all, and even happily explained in detail to her, looking like a teacher.

Su Yichen certainly knew why Luo Yan did this, and immediately looked at them with a smile and discussed how to make a dish as enthusiastically as if they were discussing a topic. It was not until a few minutes before Wan Changchun remembered that there were still two dishes in the kitchen that were not served. He patted his thigh and crawled into the kitchen again. This time Luo Yan followed in and helped him get started.

Wan Yi was arranged to other places because of work needs. Wan Changchun is basically living alone now, and there is also a nanny assigned to take care of his life. In addition, the new Shimen University has officially started, and Wan Changchun, who has returned to school, lives a fulfilling life every day.

The dishes were served soon, and there was a light tofu soup. Although it was common, the three of them enjoyed the atmosphere very much. They ate and chatted, and the room was full of warmth of the atmosphere of life.

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

First, he asked about Wan Changchun's situation at school. Wan Changchun chatted happily, and then took the question and asked Su Yichen about the progress of the Federal Academy of Sciences and their arrangements.

"The dark matter experiment has been completed. We will rush back tomorrow. If everything goes well, it will take as little as half a year or as long as a year. The practical dark matter equipment can be officially taken out."

"This is good! This is good!" Wan Changchun said happily: "Dark matter weapon is a powerful deterrent weapon. Our Earth civilization has entered the ranks of cosmic civilizations, but for the entire universe, the Earthlings are just as fragile as a newborn baby. In this case, it is extremely necessary to master such a weapon. We Earthlings can not learn from the Gaias to invade others, but we must have the ability to protect ourselves. Xiao Su, you have done a good job!"

"Yes, that's right." Su Yichen nodded slightly, fully agreeing with Wan Changchun's point of view. After entering the universe civilization, the earth's civilization must have the ability to protect itself, and the technological breakthrough of dark matter ensures this. This is the same as the nuclear weapons of various countries on the earth at the time. When the other party has such a devastating weapon, if you do not have the ability to counter, you can only be fished by the other party and cannot resist.

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

Su Yichen roughly talked about the planning of the Federal Academy of Sciences, but for the entire plan, including many experiments currently underway, Su Yichen only serves as a guiding role, and there are not many people who are truly directly responsible. In addition, Su Yichen has decided that he and Luo Yan will leave Earth soon, return to Pluto to make some preparations, and then prepare to leave the solar system to see the real universe.

"Are you a little anxious to do this?" Wan Changchun frowned slightly. It is inevitable that humans will enter the universe and truly enter the universe. He also understood the intention of Su Yichen doing this, but he felt that it was too urgent for him to arrange this.

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

"High-dimensional technology?" Wan Changchun asked immediately with his eyebrows raised. After saying that, he thought for a while and nodded in a sigh: "Yes, I know you have always been particularly concerned about this technology. If I guess correctly, you are planning to follow the footsteps of Rand civilization to find the real secrets of this technology, right?"

"Yes, this is one reason. 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 rather than stick to self-confidence. Otherwise, the situation of the Gaia civilization will reappear. In fact, I learned from the information left by the Rand civilization that the entire Milky Way is not as terrible as we imagined. The order still exists in the universe civilization. Only the more you contact, the more good it will be for the future of the earth civilization."

Su Yichen's words touched Wan Changchun. He nodded in agreement, but he still asked Su Yichen to leave only when he was fully prepared, and he had to notify him when he left.

"Don't worry, I will definitely notify you on the day of departure." Su Yichen smiled and agreed. Then he suddenly remembered something, saying that he wanted to give it to Wan Changchun. Then he took out a stack of things wrapped in paper from the bag he carried and handed them to Wan Changchun. Wan Changchun took it in confusion and then took it apart in Su Yichen's smile and gaze. When he saw what was inside, he was stunned at first, and then his hands were trembling slightly excitedly. (To be continued, please search for Piao Tianwen, the novel is better and faster!
