A sudden death while working overtime caused Lin Shu to fall from the brightly lit e-commerce office into the stormy Shanghai of 1937. As a new member of the underground party, she unexpectedly obtained the team-building system in the desperate situation of being hunted by the Japanese army. From then on, "fighting for supplies" and "fighting for allies" became her daily life as a spy.
She met Shen Yanzhi, who appeared to be a gentle manager of a foreign company, but was actually a deep and reserved head of the underground party. From the initial suspicion and testing, to the Paramount adventures in danger together, to the willingness to take risks and join forces to save each other, the two developed a restrained and firm relationship in troubled times.
Faced with cunning Japanese intelligence officers and a shortage of mission supplies, Lin Shu used modern team-building wisdom to break the situation, exchanging points for medicine to save his life, and inviting partners to fight for equipment to deliver key intelligence. She was not born a spy, but she grew up from mission to mission, choosing between personal safety and the justice of her family and country. This is a story about growing up, and it is also a love story in troubled times written in a puzzle. Lin Shu and Shen Yanzhi join hands, side by side in the darkness, fighting for the dawn.
