In the autumn of 1941, in Cangyunling, northwest Shanxi Province, 12-year-old Eighth Route Army correspondent Li Nian'an was swept away by a silver crack during artillery fire and fell into the living room of a rental house in Beijing in 2026. The black-and-white photo on the fourth page of the family tree is exactly the same as the child in his arms: ancestor Li Nian'an, who disappeared after the battle in Cangyunling in the autumn of the 30th year of the Republic of China, at the age of 12. A storage space shared by grandparents and grandchildren was activated - Li Mu was responsible for making money, purchasing, and teaching weapons, and the grandfather was responsible for bringing food, medicine, and guns back to the trenches in 1941 and giving them to Li Yunlong's new regiment. A programmer with a monthly salary of RMB 4,800 started with the first batch of life-saving medicine for RMB 812, and went on to buy Mosin Nagant, Bobosha, night vision goggles, drones, and Katyusha rocket launchers. On the battlefield eighty-five years ago, a "remember" book full of names was getting thicker page by page.
