At the end of the late Qing Dynasty, the Jiangnan silk family "Shen Yuan Ji" collapsed amid the impact of foreign cloth and the drastic changes of the times. The surviving young man Shen Weizhou was reduced from a well-clothed scholar to a refugee with a broken family. He broke into the Shili foreign market with the fragrance of ink, set up a stall in the Chenghuang Temple and wrote letters to survive, and finally entered the "Shiwen News" under the pen name "Mohen". When he saw the workers at the bottom being devoured by machines and crushed by capital, he put aside the pedantry of traditional literati and used his pen as a blade to expose the shady story of the "Yuda" cotton mill that disregarded human life in the newspaper. From the old dream in the south of the Yangtze River to the Shura field in Shanghai, Shen Weizhou witnessed the collapse of the old era and the sprouting of new ideas in the battle of pen and ink and blood, and also found his own way of survival between the lines - the pen that once wrote the sages' books will eventually be dyed into the wind and clouds of Shenjiang, leaving a mark of unwillingness to surrender in the torrent of history.
