Chen Shaoqing was a survivor of the Nanjing Massacre in his previous life. He watched his whole family die tragically under the knife of the Japanese army. He transformed into a "shadow killer" and used 132 bullets and a big knife to hunt Japanese invaders and traitors in Nanjing. In the end, he died heroically in an operation, but was unexpectedly reborn three months before the Japanese invaded Nanjing. With the memories, hatred and combat experience from his previous life, Chen Shaoqing is no longer the ignorant student, but a scheming and decisive avenger. He took advantage of "predicting the future" and made plans in advance. Not only did he protect his family members who died tragically in his previous life, he also organized an underground resistance force. In the chaos of the Japanese invasion, Chen Shaoqing transformed into a "lone wolf" and accurately hunted down his enemies in his previous life. At the same time, he secretly contacted all parties and established an intelligence network. As the revenge operation deepens, he gradually discovers a larger conspiracy behind the Japanese army, as well as a final BOSS hidden in Nanjing City - the senior Japanese general who planned the entire Nanjing Massacre. Chen Shaoqing must make a choice between personal revenge and saving more compatriots, while facing multiple threats from the Japanese army, traitors and internal traitors. In this confrontation with fate, he not only had to fight against foreign enemies, but also fought against inner hatred and loneliness, and finally grew from a simple avenger to a true national hero.
