From a Top Student in the History Department to a Hidden Blade in the Military

Chen Yu, a graduate student in the Department of Modern History, traveled to Shanghai in 1938 due to a mysterious pocket watch and possessed Lin Mo, a peripheral member of the military reunification. Relying on historical knowledge and modern thinking, he struggled to survive in the dangerous situation where the Japanese and puppets were rampant and various forces competed. He gradually grew from a young student to a calm and keen agent. Dealing with the military boss "Shadow", the suspicious Gao Zhanlong, and the CCP underground party Xia Bingqing, he repeatedly resolved crises with precise judgment, but he also fell into moral dilemmas and identity doubts. Behind the pocket watch lies the truth about time travel and family grudges. At the darkest moment when the Pacific War broke out and Shanghai fell, he had to make his own choice.
