Traveling through the remaining veins of Donglin in the 17th year of Shunzhi, his father died for his country, his books were robbed, his mother was critically ill, and Tatar missionaries were still selling Han classics in exchange for firearms! Fortunately, I brought dual memories of modern history and engineering, exchanged soap and sugar for silver, made muskets to train a team, dried salt to save the people, raided at night to steal classics, and outsmarted the traitor Qian Qianyi! From the fire in Shipanyu to protecting the Chinese cultural heritage, killing Tatars, driving out foreigners, and settling blood scores, this time, Chinese civilization will never sink!
