I Went on a Killing Spree After Becoming a Military Intelligence Field Agent

Lin Yan, a modern-day wage slave, transmigrates to the era of the War of Resistance and becomes a low-level field agent for the Military Statistics Bureau. Enemies surround her, and danger lurks at every step. One wrong move means certain death! At the critical moment, the Iron-Blooded Traitor-Elimination Achievement System activates! Kill Japanese invaders to obtain gold, medicine, and ammunition! Eliminate traitors to obtain skills, equipment, and intelligence! Save fellow countrymen and deliver intelligence to earn a massive number of achievement points and expand her storage space without limit! In public, she is a cold, capable field agent for the Military Statistics Bureau. In secret, she is a deeply concealed underground courier. Working undercover on two fronts, she navigates a perilous game and forges the sharp edge of espionage with an ordinary person's body! No male lead, no romance, no ambiguous relationships. She's focused entirely on her career! From an ordinary person trembling with fear to a decisive blade in the shadows. With the System at her side, she will defend the land! Watch her eliminate traitors and resist the Japanese amid the flames of war, protecting every inch of China's vast territory!
