After the Third World War, the world was baptized by nuclear weapons, and most of human civilization was destroyed. However, humanity did not perish because of this, and a few people still survived, living in a world ruled by violence. After World War III, the Asian continent was completely divided, and the warlords divided all the land, and they imposed a dictatorship on their jurisdictions with mutated mercenaries who had superpowers due to genetic mutations caused by nuclear radiation. Long Kui was once the strongest of these mutant mercenaries to be revered as the god of war, but when he was tired of the war and prepared to go into hiding with his wife, his wife was brutally murdered after he returned from his last mercenary mission. The former god of war picked up his seven knives again and slashed all the way across the Asian continent like crazy, looking for clues to kill his wife and enemy. But every time Long Kui took a step closer to the murderer, the mystery in his heart deepened, and he gradually realized that the murderer seemed to be brewing a shocking conspiracy that could upend the entire Asian continent.
