September 1972.

Beijing, Chang'an Street. The scorching sun is still as hot as fire, and the asphalt road is roasted like a stove. Chen Dong walked on the street alone, but his heart was filled with sadness.

He, a 21st century double-professional doctor, does not believe in God, does not believe in ghosts and gods, and does not believe in the so-called theory of time and space, but reality is cruel. No one can accept the reality of traveling through time and space to this world. He should have been born ten years later, grew up in rural Anhui, and was known as a genius since childhood. He was admitted to the junior class of the University of Science and Technology of China in the second year of high school. When he was in college, his school education reforms encouraged students to develop comprehensively, such as implementing a double degree system. Chen Dong received a double doctorate in electronics and engineering at the age of 24 because of his quick thinking and hard work. Not only that, Chen Dong also performed well in other aspects of reflecting his personal comprehensive qualities. Originally, according to the expectations of his teachers and classmates, people like him generally chose to visit scholars from a foreign university after graduation, and the least of which was also a research institution of a large company to be an expert in high-tech project. Naturally, the "money prospect" is enviable.

However, his final choice surprised countless people who followed him. Unlike others' speculations, he resolutely put on military uniforms and walked into the military camp with countless surprise eyes. At that time, in order to deal with the needs of future wars and high-tech equipment as soon as possible, the army had already begun to recruit college students from local universities to join the army. However, for those leaders who were stationed in the army to recruit college students, Chen Dong was undoubtedly a priceless treasure. Not to mention his achievements during his school days, not to mention his several papers that received attention from the academic community, not to mention his double doctoral title. He was able to abandon generous treatment and choose the army, which was enough to make these people admire him. It is said that in order to compete for him, different units did not hesitate to sue him, and their faces were red and their necks were thick. In the end, the top leader of a military region personally used his hometown cards to build relationships.

In the army, Chen Dong was like a fish in water. He used the knowledge he learned to spend two years to understand the principles of all the weapons and equipment of the military region, and transformed a considerable part of it, some of which were completely redesigned. Under his leadership and leadership, a scientific research team with different education and titles was quickly established. In the past four years, dozens of projects brought rich results to the army, greatly improving the level of the army's equipment. The achievements he and his team made amazed the scientific research institutes in the military system. Countless military-industrial units sent olive branches to invite Chen Dong to join their units. However, just as Chen Dong was about to reply to these invitations, an air crash brought him to Beijing in 1972 and occupied the body of a middle school student named Li Siming.

At this time, Chang'an Street was a sea of ​​green and red. Everyone was wearing green military uniforms and shoes and hats. This was the fashion of the whole era. Red was the red flag fluttering in the wind and the red book waving in people's hands. This was a gathering of middle school students in Beijing, criticizing all the reactionaries hidden in the people's teachers in Beijing. On the platform, the black crows were all teachers of middle school students in Beijing. It is said that every middle school has it, and standing in the audience were revolutionary teenagers: students from middle schools in Beijing.

Chen Dong looked at everything around him coldly, as if it had nothing to do with him. Yes, he was just a person from the 21st century. All the movements, revolutions, and struggles here had nothing to do with him. In the two months since he was reborn, he had heard and witnessed too many things. From the initial curiosity and shock to the present, he had only numbness, and even had a mentality of watching the show. But what should I do if I didn't call him that? This is the numbness of the entire era. Facing the collective paranoia of the people of the whole country, one person's power is too small.

"Li Siming! Li Siming!" Yes, someone is calling him, but he is still not used to this name. Chen Dong turned around and searched in the crowd. It was Zhang Hua. This guy was the first person Chen Dong met in this world except his parents. He was a classmate of the No. 15 Middle School. According to his mother, he had been playing big in the same yard as he was a child, went to school together, and was like a person.

"Siming, if you arrive a little later, Marshal Xu will curse people. Don't be upset!" Marshal Xu's name is Xu Zijian, the leader of the revolutionary young general of the 15th Middle School. He always calls himself the commander. Over time, others call him Xu.

"Why?" Chen Dong asked in confusion.

"It's not because of Old Man Zhang!"

"Who is Old Man Zhang?"

"No way? I was injured last time and lay in bed for two months. Even Old Man Zhang forgot who it was?"

Chen Dongxin said, it’s weird if I know, Zhang Hua didn’t delve into it, and pointed to the stage and said, “Look, it’s the old man who is being criticized in front of the stage.”

Chen Dong looked in the direction of his finger. At this time, the one who was being beaten in front of the stage was a thin middle-aged man wearing thick glasses. His white shirt was now colorful. There was a large wooden board hanging around his neck. It was estimated that the weight was not light, and it said:

"Defeat the Soviet revisionist Zhang Hong" is followed by three big exclamation marks.

"Old man Zhang is really stubborn. He was beaten to death a few days ago and did not admit his guilt. He is so fucking stubborn!" Zhang Hua looked around and lowered his voice and said, "Marantor Xu has become so many revolutionary young generals today. He has lost face and has nowhere to get angry. Be careful!"

In the evening, the conference ended, and Chen Dong and Zhang Hua returned home together. This is a typical house for a couple of workers in Beijing. The house is not big, so a side house was added to serve as a kitchen. There is only simple furniture in the room, and the only one that can be called household appliances is a bulky radio. This was bought by parents who saved money.

Chen Dong first cleaned up the house and looked around. There was a sour smell in his heart. In his previous life, his parents died early. Although he had some success later, what made him regret was that his son wanted to raise his parents but his parents were not there. In this era, his parents were both there, and they lived a hard life, but they were very satisfied and cared for him very much. But if they were letting them know what would be like if Li Siming was not Li Siming. Chen Dong felt guilty.

Li Quan and Shen Fang returned home together. They worked in the same textile factory. As soon as they entered the house, they were stunned: the windows at home were clean, the dining table that they had no time to clean when they were at work was wiped clean, the clothes they had changed were washed and hung in the yard, and in the kitchen, the son was cooking while whistling. His son knew that although he had never made any big mistakes since he was a child, he had never been so diligent!

"My parents! You are back, the meal will be fine in a while!" Chen Dong greeted with a smile. He was ready to think about it. Since he came, he would be at peace. From now on, he would be Li Siming and he should be filial to his parents. Li Quan and Shen Fang were so moved that they were confused. Since the last time they were injured, their son seemed to have changed into another person, becoming self-disciplined, quiet, sensible, and matured like a thirty-year-old adult.

"Son, what are your plans in the future?" Mother Shen Fang asked while eating the delicious meals made by her son.

"I don't know." Chen Dong also asked himself this in his heart. In this era, he was just a middle school student who had not yet fully studied in high school. He went to college and had no chance. The entire education system was paralyzed, so it was impossible to go to college. He was not a worker, peasant and soldier, otherwise he could also recommend going to school.

"I heard that the Party Central Committee has called on intellectuals to go to the countryside again. Will our Siming family go there too?" My mother said to her father with a worried look on her face.

"This is the central government's call. Not to mention high school students, even junior high school students have to go!" said his father Li Quan.

"Our Siming has never done farm work. I heard that some of them have to go to Heilongjiang, which is cold and cold, and some have to go to Xishuangbanna, which is also a tropical rainforest, and it is not a place for people to stay."

"Our Siming is not an ordinary person. He will do something wherever he goes, right, Siming?" Li Quan blew up a little to comfort his wife, who was usually quite real. He didn't expect that his son had really done countless big things that he had never thought of, and it was more than just a few actions.

"Of course, parents, don't worry, my son has grown up and will take good care of himself. When I am not by your side, you should take good care of his health." Chen Dong is very capable of getting into the state of his role as a son. Seeing his son so sensible, the couple felt somewhat at ease.

In the evening, Chen Dong sat at the desk and flipped through the diary written by the body owner Li Siming. Fortunately, Li Siming had the habit of writing diaries, otherwise, Chen Dong would be worried if he would reveal himself.

Li Siming, born in 1957, is still one month or 15 years old this year. He is said to have graduated from high school, but at best, he is at the first grade of junior high school. Because of the continuous movements, education has been severely impacted. Criticizing and fighting against the stinky Lao Jiu is the main task of Li Siming and his classmates. The education hardware was destroyed and the teacher team was hit. What is destroyed is not only the education of a generation, but also the future of a generation. In school, either helping farmers harvest in summer and autumn, or receiving military representatives for military training, and then participating in movements again and again, and of course, there are also the teachers in the school.

"If you should come, let it come. From now on, there will be no Chen Dong in the world, only Li Siming!" Chen Dong, no, it should be Li Siming shouting silently in his heart.

The next day, at half past six, Li Siming had already got up, then washed up and went out for morning exercises. This was his habit in his previous life, because he believed that the body was the capital of revolution. When he came to this world, he naturally followed this truth. It just made him not very clear that this body was really great. The strength and flexibility were incomparable to the previous life, probably the result of time travel. I remember that I had been lying in bed for two months, and the previous month was in a coma every day, and felt that my whole body was in great pain every day, just a piece of iron was repeatedly beaten by a blacksmith.

The streets in the early morning were deserted, red, black flyers, big-character posters everywhere, and the content was also varied, such as "defeat the XXX bourgeoisie ruling faction", "defeat all monsters and monsters", "defeat the Soviet cultivators XXX", etc., which were radiant in the wind.

When I ran through several streets and came to a vegetable market, a gray figure attracted him. It was Zhang Hong, the teacher who was beaten yesterday, who was picking up the vegetable leaves thrown by someone else on the roadside. Seeing Li Siming walking straight over, standing by the wall like a frightened bird, the dirty snakeskin bag was tightly held behind him, and behind the thick glasses was a pair of extremely frightened eyes.

Li Siming realized that he was scaring him and quickly put on a very friendly smile: "Teacher Zhang, don't be afraid, I won't harm you."

Seeing Old Man Zhang's eyes that seemed to be resigned to fate, I couldn't help feeling sad. I took out some food coupons, oil coupons and some money from my pocket and handed them to him. It was the one left over from Li Ziming's housework these days. I didn't dare to give it too much. The food and oil in the house were also metered. Old Man Zhang was stunned, but Li Ziming didn't say anything and stuffed it into his hands.

"Winter has come, will spring be far away? Live well, one day the sun will shine on the earth!" Li Ziming said this in Russian. What he didn't know was that Old Man Zhang also studied Russian.

When they got home and prepared breakfast, their father Li Quan and mother Shen Fang also got up. They ate the breakfast made by their son. They were very happy. After a few words, they went to work together. They both worked in the clothing factory. The father was the workshop director and the mother was the factory accountant.
