Hong Se Te Gong plot
On the eve of the Liaoshen campaign, the Northeast Field Army attacked the provinces around Jinzhou and surrounded Jinzhou. The intelligence agent codenamed "Green Snake" was arrested, and Lin Xi, the head of the Confidentiality Bureau with heavy responsibilities, was ordered to go to Jinzhou to conduct a thorough investigation into the incident. Lin Xi was actually a red agent whose secret mission was to save the "Green Snake" and help him hand over the defense map of Jinzhou city to the east outside the city to support the attack on Jinzhou. However, unexpected problems surfaced.
