Zhao Tiezhu, who was once trapped in a quagmire, accidentally ended up in the war-torn wilderness battlefield. The broken walls turned into trenches for hiding, gunpowder smoke shrouded the wilderness all day long, and the old military uniforms were covered with scars. There is no halo from heaven, no legend of victory, just a group of ordinary people caught up in the war: foreign youths and downtrodden veterans, who hold together to survive in the gunfire and mud. Seeing through the devastation of human nature, he struggled to breathe between life and death. When the gunpowder smoke slowly dissipated, those who survived the blood and earth of the corpse mountain carried the marks of the battlefield on their backs and dragged their bodies full of exhaustion towards the long and heavy rest of their lives.
