, I recommend the following novels to you to satisfy your requirements ~ 1. "Anti-Japanese Ace Agent": The protagonist was a special national security investigator who later became a red ace agent during the Anti-Japanese War. The plot was compact and exciting, but it was not overly imaginative. The details were very realistic. 2. "Fox of the Spy Sea": The protagonist is a special agent who fights for the national interest and national justice. Not only does it have a wonderful plot and description, but it also shows the protagonist's deep friendship with the country. It is very attractive. 3. "The Return of the Soldier King": The protagonist is a soldier king who returns to university after going through all kinds of hardships. The fast-paced plot is compact, realistic, relaxed, and humorous. It's very enjoyable to watch. I hope you like my recommendation, Mwah ~😗
