The time traveler Li Qiuyi took advantage of the detente between China and the United States in the special era to go to the United States for further study. He obtained a master's degree in aerospace from Michigan and worked intensively in an overseas laboratory for two years. He accumulated a large amount of industrial materials, equipment and foreign exchange, and had his own demi-dimensional space where he could hide and store items. In the spring of 1982, he resolutely returned to his hometown and returned to the courtyard in Beijing. As soon as he was admitted to the hospital, he encountered a quarrel between Bangge and Shazhu, preparing to rely on advanced aerospace technology to seize the opportunity of the reform and opening up era.
