In 1958, Xiao Yunze filled the Siheyuan with letters, and the Dimension chat group automatically recognized its owner, and Qin Shihuang was the first to join the group, followed by Zhang Sanfeng, Yan Chixia, and Yue Buqun. Ying Zheng purchased high-yield potatoes to stabilize the Qin Dynasty, Zhang Zhenzhen saved Cuishan and his wife, Yue Buqun gave up warding off evil spirits and practiced the Yi Jin Jing, while Xiao Yun took advantage of the dividends to practice martial arts. Working as a welder in a steel rolling mill, he helped He Yuzhu arrange his marriage, criticized the second uncle's hypocrisy, and used group chat resources to plan ahead in 1958, treating all the best in the hospital as tiny dust in the general trend of the world.
