Entering the Spy War: Borrowing the Identity of the Eldest Lady

I just stayed up late and read a spy novel. Unexpectedly, my eyes suddenly darkened, and I transformed from a female college student in the 21st century to an overseas daughter of the president of the Shanghai Bund Chamber of Commerce. I originally planned to take advantage of my father's capital and secretly aid the patriotic cause, but I found that I was not transported to the real Republic of China, but to the spy novel "My Spy Years" that I was reading. Before I could calm down the excitement of meeting the male protagonist, a newspaper advertisement suddenly activated the memory of the original protagonist—— Gan! I'm the one lurking the deepest! On the surface, she appears to be an innocent and kind lady who is ignorant of the world, but in reality she is a professional agent. The scary thing is that my character has never appeared in the book, leaving me with all the unknown. The male protagonist is indeed handsome, and the father is indeed good. But I have a gun in my sleeve and Morse code in my head. During the day, she acts coquettishly and buys cheongsams, and at night, she sends reports and gathers information. Miss, (hands over) I can lend you your identity. "My Spy Years" fanfic/no cp/spy war
