Winter 1942, Shanghai occupied area. The Wang Puppet Traitor No. 76 Was on the rampage. The small leader of the Yixing Society, Gu Songmiao, was betrayed and his brothers died tragically on the street. In a desperate situation, he accidentally activated the "anti-war material exchange system" - but the system could only exchange limited bullets, which was far from enough to overturn a devil's cave. Gu Miao summoned six living and dead brothers: Xiao Yanhui, a cold-faced female sniper, Huo Zhanfeng, an orphan from the Ax Gang, Mei Ruosheng, a poison expert, Qin Tiezhu, an explosivesman, Luo Wenying, an intelligence expert, and Ye Qianfan, a pretender with a thousand faces. The seven people used the righteousness of Jianghu as their blades and accepted the secret instructions from the military commander and the Allied Mei Agency: to break into No. 76, Uncover the high-level traitor, and destroy the Japanese secret weapon "Sakura-11". A precise headshot of a traitor with a blood debt, and a narrow escape from death by overturning the system. But the traitor is hiding in the dark, and every victory is stained with the blood of his teammates. As the third volume begins, some people begin to fall... When sacrifice becomes the only way to surrender, can the seven-man death squad tear apart Dawn?
