Spy War 1937

This book was originally titled *Spy War 1937: My Cheat Code is My Cellphone* and *Spy War: The Military Intelligence Bureau's Never-Existent Agent*. It's a story of espionage during the War of Resistance against Japan, involving the Military Intelligence Bureau, a cunning and opportunistic approach, prioritizing personal safety and comfort, and devoid of heroic spirit. Han Zhenhua, a modern high school graduate, unexpectedly travels back to Shanghai during the War of Resistance in 1937. He discovers that although his cell phone has no signal, its AI software works, becoming his greatest cheat code. By chance, he is mistaken by the Military Intelligence Bureau as an external intelligence agent codenamed "Crow." He then uses the intelligence he finds on his phone to provide accurate information about the Japanese and their collaborators, gradually rising from a nobody to a top-tier Military Intelligence Bureau agent hidden in the fog of war. Enraged, the Japanese conduct a massive investigation of all intelligence systems, but find nothing, because his cheat code is his cell phone search; he doesn't need to work for any Japanese intelligence department!
