Li Yunlong, a fierce warrior who has fought countless battles in the battlefield, stepped into the gate of the Military Academy in peacetime. He thought he would be able to put away the smoke and flames of war, but unexpectedly he was involved in a secret war that spanned more than ten years. From the sand table simulation at the Military Academy to the abandoned shrine on the outskirts of Nanjing, from the biochemical laboratory in Changbai Mountain to the smuggling dock on the Huangpu River, he started a life-and-death game with his former rivals, the Yamamoto family, and uncovered the shady story of the "Pangolin" spy organization left behind by the Japanese army.
Faced with the collision between modern warfare concepts and traditional combat thinking, Li Yunlong had a fierce confrontation with Kuomintang general Chang Naichao in class, but unexpectedly discovered that his opponent was a red agent who had been lurking for many years; when his wife Tian Yu was criticized for her "bourgeois style", the couple supported each other in the tide of the times and jointly protected their beliefs. With the appearance of the jade pendant and the resurgence of the cherry blossom bug, Yamamoto Jiro's evil plan came to light. His former comrade Kong Jie died heroically, and the bloody feud between Chang Naichao's family was also exposed.
On the battlefield where technology and conspiracy intersect, Li Yunlong leads the Liangshan detachment deep into danger, and Tian Yu relies on medical wisdom to solve the biochemical crisis. They use flesh and blood as a shield and the spirit of the sword as a sword, vowing to cut off the enemy's poisonous claws. This is not only a battle to defend national security, but also the rebirth of a legendary general in the new era. It witnesses how the hero's blood continues to boil in peaceful times, composing a magnificent hymn of loyalty and faith...
