Cannon fodder Second Lieutenant Lu Zheng picked up the dying military doctor Chu Xiu from the ruins at the edge of the battlefield. He thought he was just an additional burden, but he didn't know that this man held a secret file that could tear the entire military regulations into pieces. When his superiors ordered the execution of civilian prisoners to deter the enemy, Lu Zheng shot and killed the order messenger in public, staining the military emblem with blood. Chu Xiu silently tore off the blood-stained copy of the military regulations and stuffed the evidence into his palm - that was the last truth left by their common father. From then on, Lu Zheng was no longer a tool to obey orders, and Chu Xiu was no longer a medical officer hiding behind the scenes. They broke into the dark side of the war side by side, just to let the truth reach people's hearts faster than bullets.
