January, 77th year of the New Calendar.

There were traffic outside Nanjing. Song Beiyun, who was already 95 years old this day, proposed to go out for a walk, but no one around him agreed, because Mr. Song's health has not been very good these days, especially after his wife Zhao Ling, who had been with her for more than 70 years, passed away, his spirit became much more depressed.

But he had to go out for a walk today, and no one could stop him, and he didn't need others to follow him. He walked out alone with the same old Qiaoqiao, leaning on a crutch.

The two of them walked around and stopped, but they didn't know how long it took to finally stop in front of the ancient city tower in Nanjing.

It is said to be an ancient city tower, but it is actually the former site of Nanjing City. In recent decades, the city has developed rapidly, and Nanjing City has expanded outward very quickly. The original outer city has now almost become an existence in the city center. The ancient city tower has almost become a scenic spot, and people come to visit every day.

Song Beiyun sat in the resting place outside the city, looked up at the towering city wall and the mottled words "Jinling City" on the city wall, and suddenly laughed.

"Qiaoqiao."

Qiaoqiao is in good health, and she has become the one who has been with Song Beiyun from the age of seven to the age of ninety. The two have been together for the rest of their lives.

"Qiaoqiao!"

Seeing that she did not respond, Song Beiyun strengthened her tone, but Qiao Qiao still did not respond, so she had to poke the instep of her feet with the crutch in her hand.

"Ah?" Qiao Qiao turned around and looked at him: "Call me?"

Song Beiyun pointed to the plaque in Jinling City: "I remember it has just been repaired not long ago, why is it so old?"

Qiao Qiao listened carefully for a long time before she said and gestured, "It has been more than seventy years, and it has been more than seventy years of cultivation."

After hearing this, Song Beiyun didn't say anything, just quietly staring at the plaque on the city gate.

It has been more than seventy years? It has been more than seventy years before I knew it.

Yes, the Jinling City Gate, which was heavily guarded by the time, has now become a free park with people playing in front of each other, which is quite interesting.

At this time, someone's singing sound came from somewhere, which was loud and loud, which was the song "Ding Fengbo" that Song Beiyun loved the most back then.

He listened to the voice, smiled, patted his thighs and responded softly: "Bamboo sticks and straw shoes are lighter than horses, who is afraid? A raincoat will last forever..."

At this moment, snow began to float in the sky. Song Beiyun suddenly thought that many years ago, he came to this world on such a heavy snowy day. He stood at the entrance of the village and was trembling with coldness. The first person he met was the wrinkled old woman sitting opposite him.

At this time, under the city wall, a boy raised his head and looked up at the vicissitudes of Nanjing City with his bag on his back, muttering quietly. His accent did not look like a southerner, with a somewhat northern accent, and his figure was quite tall and handsome, but his eyebrows were a little frivolous.

"Chen Songping!"

A girl from sixteen or seventeen years old in front of him was angry and yelled at his name: "What are you looking at again! Just be careful when you are usually slow, you will be slow in the exam, and you will be in the afternoon. If you fail the final exam, you will be dead! Don't expect me to give you some lessons during the winter vacation."

"Here you come, you're urging and urging every day, urging you to be reincarnated!"

"What did you say?"

"I said you're so beautiful today."

The girl was wearing thick clothes and a bag cross-body. Although she was a little thin and had no S-shaped figure, she was more powerful than aura. Every frown and smile brought the pure agility unique to a fifteen- and sixteen-year-old girl, without any dust.

After agreeing, the boy named Chen Songping turned his head and looked at the old man sitting in the pavilion next to him, then nodded slightly, and then accelerated and ran over to catch up with his female companion.

Song Beiyun was a little dazed for a moment. He seemed to have seen this scene somewhere, but he couldn't remember it all at once. He looked at Qiaoqiao next to him. He was about to speak, but Qiaoqiao said, "I used to urge you like this. That day we entered the city and picked up dog eggs."

Well, we entered the city that day and picked up dog eggs.

But that was more than seventy years ago.

Song Beiyun felt a little tired, so he leaned on it and took a nap, with a smile on his lips. ——

April, 474, New Calendar.

In the 52nd year after mastering the controlled nuclear fusion technology, humans completed the curvature engine test for the first time, and finally walked out of the solar system that had been trapped for hundreds of thousands of years, began to move towards Sagittarius, trying to open a second home. They named the first spacecraft used for exploration, the Song Beiyun, and the destination E493-type earth planet was also named Song Beiyun Star to commemorate the great scientific pioneer Song Beiyun.

"Old Zhao, you said that such a powerful person really only left such a little thing after his death?"

A graduate student from the history department stood in front of Song Beiyun’s tomb on the back mountain of the campus and looked up and down, then placed a bottle of wine and a pack of cigarettes on the platform of Song Beiyun’s statue, and put his hands together: “Bless the students to pass the topic…”

Behind him was a middle-aged man with a crutch, his mentor. He called Lao Zhao because this mentor had a peaceful personality and could always get along with young people.

After hearing his words, Lao Zhao laughed: "What did you say? Say it again."

"I said that Song Beiyun is such a powerful person, why did he just leave such a little thing after his death?"

Unlike the tombs of kings, princes, generals and ministers, Song Beiyun's tomb is on the campus of Northwest United University, with a statue and a tomb. After that, during the graduation season of the school, students from the history department will come to repair and maintain it, so his tomb will be like new every year.

But unlike the large tombs discovered in history, it has no underground palaces, no luxurious decorations, and no cemetery. It is just a small tomb of ten square meters square. The funeral objects inside are a booklet, which records some major events of history and era, a photo album, and contains family and friends and some key historical figures at that time, as well as a bowl of plum vegetable pork, a bowl of steamed salted fish, a bowl of roasted lamb legs and a bowl of tomato and egg soup, as well as a bag of potatoes, a bag of corn, and a bag of pepper.

There was nothing else, and it was simply thought that his tomb had been stolen.

"Think about it carefully before talking, otherwise your project will definitely not be able to pass." Lao Zhao said half-jokingly.

The student slapped his head: "Yes, yes, yes, I'm wrong. He and Confucius were only sages in the world, and the things left behind are not a little bit."

Only after Lao Zhao's prompt did he realize that he was saying the wrong thing, because the things left by Song Beiyun were not measured by wealth. The opening of the science discipline alone was enough for him to shine for thousands of years, let alone he firmly defended China's idea of ​​unification.

As a student in the history department, he clearly knew that according to the historical records left behind that year, the period when Song Beiyun appeared was the weakest period of the Song Dynasty, and there were also Liao and Jin dynasties at the same time.

According to the laws of historical development, the Song, Jin and Liao Dynasty eventually broke into each other and broke into each other. At this time, the northern nomadic peoples would definitely take advantage of the opportunity to enter and tear the entire world apart.

Although the development trajectory of human beings must be similar, and without Song Beiyun, there would be others to enlighten science, that person may not be Chinese, and China may not have good development in the future. Then the current world pattern may be completely different.

Therefore, the old man on the statue has a historical boundary with Song Beiyun as the boundary. It was called ancient in the tenth year of the New Calendar before Song Beiyun ruled, and after his death, it was called modern and modern.

"Old Zhao, don't you really realize that you look very similar to Zhao in Mr. Song's album? And your surname is Zhao."

"Didn't you find that you look very much like Song Beiyun?"

"Hahahahaha... I feel it's like it, especially when he was young, I was just carved from the same mold. If my surname wasn't Cao, I would have thought I was the son and grandson of his Song family."

Old Zhao spat: "The handsome guys in the world look similar. Zhao Xing and I are both handsome guys, and they are normal for them to look like each other."

"You are a master of nonsense. You are such a role model. You are really weird."

After saying that, he took out a pack of cigarettes and lit a piece in front of Song Beiyun's statue, turned around and said to Lao Zhao, "Let's go, don't you say you're coming to a new junior sister today, take me to see it."

"Don't worry, I made an appointment with someone to come here. She should be here soon." Lao Zhao glanced at his watch: "It's not me who said you, he's a soft girl. When you come later, don't be like a hungry wolf."

"I am a handsome man, look at me." He pulled his eyes and walked to Lao Zhao: "How sincere."

"Oh, let's go." Old Zhang pulled open his head.

And just then, Lao Zhao lit the bracelet and started talking: "Okay, we're waiting for you here."

After hanging up the phone, he looked back and said, "He's here, be serious."

After a while, a short-haired girl walked from the path. She had fair skin and a small figure. She felt glorious after applying some lip balm.

"Wow... the beauty is here!"

Old Zhao rolled his eyes, and the girl walked up and said, "Hello Teacher Zhao..."

"Let me introduce it. This is your senior brother. If you don't understand the topic in the future, you'll be fine." Old Zhao pointed at the boy: "Why are you talking, why are you standing there?"

"Have I seen you somewhere? I feel so familiar." The little beauty tilted her head and looked at her for a while, then suddenly reacted, stretched out her hand and smiled, "Hello senior brother, my name is Yu Peipei. You can call me Xiaoyu like the teacher."

"Cao Du!" Lao Zhao shouted: "What are you doing when you hold someone's hand?"

"It's Cao Lu..." Cao Lu raised his head and looked at Lao Zhao: "It's strange... I also think she is so familiar. I seemed to have seen an hallucination just now."

And he was just surprised, but the little beauty opposite was frowning at this moment: "What did you see? I saw... a carriage?"

"Yes, yes, yes, carriage!"

Lao Zhao shook his head and snapped his fingers: "Let's go, treat you to dinner, stop talking nonsense, your routine was no longer popular two hundred years ago."

After saying that, he turned around and looked at Song Beiyun's statue deeply, then turned around and left. ——
