In 1939, special operations captain Ren Haoran led the "Cang Lang" team deep behind enemy lines to rescue the agent "Blue Bird" who had top-secret intelligence. Facing the numerous traps of the Japanese aggressors, the special forces relied on their iron-blooded faith and peak tactics to smash the enemy's sinister biological and chemical weapons conspiracy, and composed a passionate hymn to resist Japan and save the nation!
Exciting!
