In 2026, Lin Dong, a doctor of mechanical engineering, sacrificed his life to save others and was reborn as Lin Jiye, a dropout boy from rural North China. With knowledge and beliefs that transcended the times, he started by repairing a tractor, was admitted to the Beijing Machinery Industry School, was sent by the government to study in the Soviet Union, and finally entered the core research institution of the Ministry of Machinery Industry. However, his true identity is the secret technical person in charge of the code-named "Office 07". He has spent most of his life in top-secret files - leading the research and development of domestic high-end CNC machine tools, breaking through the Western technology blockade, and becoming the "soul of industry" of the country's most important tool. However, due to confidentiality discipline, his name can never appear in any public honors.
