I recommend you to read " The Bright Sword: From the Rebirth of Zhou Weiguo ". This is a military-war-themed novel. The protagonist traveled to the era of the Bright Sword and became Zhou Weiguo, who had just survived the Jinling battlefield. Together with Li Yunlong, he turned the entire northwest of Shanxi into a nightmare for the Japanese army. The plot of the novel is intense, and the characters have distinct personalities. I believe that you will find the feeling of traveling back to Shanxi in the Republic of China. I hope you like my recommendation.
