I'm Not a Soldier, I Just Want to Live

Desperate, he was tricked into getting on a truck heading to a war zone with a high salary. The first time I went to the battlefield, my gun was shaking, my legs were weak, and my ears were filled with screams and explosions. There is no system, no bloodline of the God of War, I'm just an ordinary person who can't even hit the target. People around me fell down one by one, All I can do is survive. Not for glory, not for being king, Just to live and take another look at the sky in my hometown. (Realistic/mercenary/depressed/survival/no fun, no cheating)
