The night Shen Yan was killed by the Japanese army, he tasted blood. That was the first time the Shen family's ancestral five-flavor bloodline awakened. From then on, he could sense murderous intent with the tip of his tongue and track enemies with his sense of smell. Under the pseudonym Shen San, he sneaked into the cooking class of the Japanese military police and used a kitchen knife to cut vegetables and people. Gendarmerie captain Sato loves to eat his braised pork, but he doesn't know that the meat contains intelligence; military translator Liu Qingluan quarrels with him every day, but puts his life in his hands. Until that day, Sato asked him with a glass of wine, Shen San, where is your hometown? The spoon in Shen Yan's hand paused. The pot of soup simmering in the pot smelled wrong.
