Agent Sick Yangzi: Stirring up the Situation in Shanghai

In Shanghai in 1949, I was a "sick man" who needed to take medicine every day, and I was also the ace spy buried deepest by the enemy. They used my lost sister as a "hostage key" to hold me hostage. From then on, I acted in front of my most trusted brother, maneuvered in front of my most ferocious comrade-in-arms, and handed out half-truths and half-false intelligence to the elegant devil. When the knife fell on the city-wide blackout, everyone rushed to the front line. No one knows that at the center of this storm that determines life and death in Shanghai is actually me, the patient who is coughing up blood in the archives and counting how long each pill will last. I was on the edge of the abyss, playing the last game of survival for my sister and myself.
