Enemy-Occupied Territory: I Became a Gun and Lurked with the Protagonist

"You are the protagonist, then who am I?" "You are a gun." Traveling back in time to 1940, Zhao Donglai had to accept the fact that he was a gun. As a gun, he could only cooperate with the protagonist Xiao Zhang Jianjun to obtain intelligence on the ground, hiding his merit and fame. However, as the system was upgraded, he discovered that, hey, he could not only transform into a gun, but also a cup, a saber, and even the personal clothes of the colonel's wife... This was more fun than being the protagonist.
