In 2024, Lin Weidong, an associate researcher at the Beijing Institute of Materials Science, spent three years to overcome the world's materials science problem of controlling the interface segregation of GH4169 high-temperature alloy. However, when he submitted an article to "Natural Science", he encountered the signature robbery of his tutor Zhang Hongyuan. After adhering to the bottom line, he was expelled from the teacher and unfortunately suffered a car accident. He accidentally traveled back to 1982 and became a freshman in the Materials Department of Yanbei University of Technology;
With the knowledge of materials science forty years later, he used paper writing as his edge in the 1980s, when scientific research resources were scarce, academic thresholds were strict, but the campus was full of vitality. In the process, he not only made up for the academic regrets of his previous life, but also fulfilled his original intention of "writing thesis on the land of the motherland" while balancing his studies, dormitory brotherhood and ignorant emotions, transforming from a humiliated scientific researcher into the backbone of the industry leading breakthroughs in materials science in China.
