The river network in Qingyuan County is like blood, and Japanese and puppet army motorboats patrol day and night. Shen Chuan wore a white coat and walked through the checkpoint every day. In addition to surgical instruments, there was half a roll of medical gauze in his bag - that was his cover for transmitting intelligence to the New Fourth Army. Kameda Masao's sakantō smashed the household registers of three villages and asked the Epidemic Prevention and Control Bureau to "screen" all fever patients. Shen Zhuan knew that the so-called epidemic prevention was to force out the wounded hiding in the reed swamps. He hid sulfonamides and hemostatic forceps in the middle of the medicine cabinet. Every time he saved a civilian, he added one more item to the trust book of the Japanese army. Miura Koichi's special agent team targeted the county clinic because someone saw a military flashlight being used in the operating room. Shen Chuan's sister Su Wangdi came to deliver food, but was stopped outside the door and interrogated for half an hour. He heard his sister's cry through the curtain, and the sutures in his hands did not shake - he knew that any mistake at this moment would turn the whole family into "publicity material" in Qingxiang District. The real hot spot came from Gu Yanling.
