    ?

    There was hot cicadas chirping outside the window, the hot sun cast bright spots on the ground, the fan above the head squeaked and squeaked, and the lukewarm heat wave rustled the textbooks on the desk.

    The summer of 1991 was also extremely hot.

    Le Jing sat in the first row, very close to the old man who was standing on the podium giving a lecture, very close, the distance between the two would not exceed one meter.

    This is the solid state physics class of Tsinghua Graduate School. There are only thirty or so people scattered in the huge lecture hall.  Le Jing is here for class.

    The old man on the stage is very old, her hair is all white, and her back is a little bent because of long hours of desk work, but her eyes are still clear and moving, and her voice is still full of energy.

    The classroom was very hot, and there was no fan on the podium. The old man was sweating profusely, but he still tried his best to stand with his back straight, and gave them lessons with a loud voice.

    There was once a student who couldn't bear to see that she was still in class for a few hours at this station when she was a lot of age, so she moved a stool for her to sit on, but she declined.

    ? At that time, the old lady waved her hand, with a smile on her face with the peculiar stubbornness of an old-school scholar, "When I was in school, my husband taught class standing up. How does it look like sitting down?"

    At that time, Le Jing was sitting in the last row, watching her quietly.

    The old man standing on the stage is 79 years old, with white hair like snow, and his name is Li Shuran. He is Li Jingran's younger sister, but not Li Jingran's younger sister.

    And he was named Chang Jingchen in this life, and he was a student who came to take classes.

    He came to take classes two months ago.

    In fact, he has already mastered everything Li Shuran said.

    For this, we must thank the black technology from the future.

    In the distant 26th century, brain-implanted learning chips have become popular.  This means that in the future, people do not need to study hard and memorize knowledge step by step. They only need to implant relevant chips in the hippocampus of the brain, and people can read relevant knowledge.

    If the human brain is regarded as a computer host, the learning chip is equivalent to a built-in memory card, which will undoubtedly greatly shorten the learning time of future people.

    But this does not mean that people in the future do not need to learn.  They just remember the knowledge, and if they don't understand it, they can't use it.  Just like people who don¡¯t know much about it, even if they memorize the entire encyclopedia, they will only become a memorizing machine with an empty brain.

    So the role of the learning chip is to shorten the process of human brain memory.  And its sky-defying function is that it is a permanent memory, which means that people in the future will never forget the knowledge in their minds.

    Therefore, even though the system has implanted the learning chip into Le Jing's brain, and he has the knowledge of related subjects in his mind, he still needs to learn and understand before he can use the knowledge.

    Moreover, human energy is limited after all, and it is impossible for Le Jing to learn the knowledge of all subjects. Although he has a high IQ, he is not an omnipotent superman.  Therefore, after careful consideration, Le Jing set his own research direction as the development of rocket engines for manned spaceships.

    Fortunately, Le Jing is not stupid and can work hard, so after two years of systematic study, he has initially mastered the relevant theoretical knowledge.

    Logically speaking, Le Jing's learning direction is not related to the related courses of materials science taught by Li Shuran.  But he still comes to class on time every week.

    As for the reason, Le Jing thought, he probably just wanted to meet an old friend.

    Even though he knew that this Li Shuran was not the Li Shuran in his memory, he still wanted to come and have a look.

    He wanted to see for himself what his once shy little sister had become.

    Thinking about Li Shuran's life experience, Le Jing couldn't help feeling a lot of emotion.

    Although he died, he left a lot of royalties to Li Shuran as an inheritance, and the copyright of his book will also be inherited by Li Shuran, and the manuscript fees for reprinting books in the future will also be handed over to Li Shuran.

    That is to say, even if Li Shuran doesn't work or get married, she can live a wealthy and stable life of rice insects only by relying on his inheritance.

    But Li Shuran did not.

    She studied hard and desperately.  Then in the seventh year after his death, at the age of 21, she was admitted to the Department of Physics of Tsinghua University, and three years later, she went to study abroad at Princeton University in the United States.

    She was 24 years old at the time, and her postgraduate and doctoral research directions were materials science in physics.

    When the People's Republic of China was founded, she was 37 years old. At that time, she was already a PhD in materials science and a professor assistant at Princeton University. Her supervisor had planned to recommend her to be a lecturer.  She is also married in the United States, and her husband is a classmate with her like-mindedness. They have two lovely children.??You left a letter.  "

    At that time, she felt uneasy, and asked with a forced smile: "Is there anything that brother can't say directly? Why do you still write to me?"

    The elder brother rubbed her head vigorously, she couldn't see his expression clearly, only heard him reply with a light smile: "Because my elder brother is very shy, I can only tell you some things in the letter."

    She was still too young at the time.

    She ignored all signs of danger, and naively thought that her brother would recover from illness soon, and they would continue their warm and ordinary happy life that belonged to mortals.

    Then she watched her brother go away step by step. At that time, she suddenly felt a great anxiety, as if her brother was about to walk out of her world step by step.

    She couldn't help shouting: "Brother, come back early, I'll wait for you at home."

    The elder brother did not answer her, but turned sideways, with a gentle smile on his mouth, waved to her, and then left without looking back, his cloth shoes hurried and firm, as if he was heading for the battlefield of iron and fire

    It also seems to be telling her with her back that there is no need to chase.

    This was the last time she saw her brother clean and fresh, with a gentle smile.

    From then on, when she dreamed back at midnight, she would always dream of her brother's bloody body and his horrific festering corpse.

    The suicide note on the desk has completely become her demon.  Every time she thinks about it, she always feels pain in her heart, and it is difficult to fall asleep.

    The unknown boy from another school turned and left. Looking at his back, for some reason, Li Shuran suddenly felt familiar panic and fear.

    She asked loudly: "What's your name?!"

    The boy paused, turned sideways, with a gentle smile on his lips, "My name is Chang Jingchen."

    He waved to her and said, "Teacher, goodbye."

    Chang Jingchen ah.

    Li Shuran didn't know what kind of answer she was expecting. She shook her head with a wry smile, waved back to the boy, and said softly to the boy and to the firm back in her memory: " goodbye."

    ¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù¡ù

    I will recognize my sister!

    I promise!

    And, the prototype of Li Shuran's experience after returning to China is Mr. Wang Chengshu. This lady changed her career twice to meet the needs of the country, and relearned nuclear physics-related knowledge after half a century. She is a very great person.  Interested children's shoes can Baidu the life of the old man. The old man lived a long life at the age of eighty-two.
