In 1941, at the darkest moment of the Japanese raids in North China, Li Yunlong's independent regiment suffered heavy casualties and was in dire straits. An unfounded and top-secret order suddenly arrives: abandon the position, enter Death Valley, and carry out a secret mission in which you will be a deserter if you fail, and you will win with no name. With no reinforcements, no supplies, and no status, Li Yunlong disobeyed military orders and formed the Eighth Route Army's first nameless sharp knife squad, which went deep into the uninhabited restricted area of the Taihang Mountains and uncovered the Japanese army's long-hidden shocking conspiracy - a biochemical weapons experiment code-named "Withered Grass Project". Once released, the North China base will turn into a living hell. The secret battle is silent, the blade drinks blood.
He has to face not only the three-party siege of the Japanese elite special operations forces, Wang puppet spies and the National Army intelligence team, but also the infamy of "escaping from battle" and the heavy pressure of internal accountability and military law. The sharp knife is out of its sheath, and it will never come back.
When the biochemical base collapsed and the Kucao Project was completely bankrupt, half of the comrades of this team who defended the country with their own flesh and blood were buried deep in the mountains. Only Duan Peng and the monk survived. They won a secret battle to protect their country that could rewrite the tide of the war, but they had to seal their record forever and hide their names, so no one knew or remembered it.
