In the twenty-sixth year of the Republic of China, as the war broke out, Ah Xiu, an orphan girl who was born with an amazing sense of smell, followed a wisp of cold incense in the back alley of a spice shop and met the legendary perfumer Gu Xiangtao. He took her in as a "living spice discriminator" and taught her all his life's perfume making skills. He also made her "Light Picking" incense to cover up the sadness that had been hidden in her body for half a life, and the two lonely hearts gradually fell in love in the fragrance mist.
The Japanese army came with iron hooves and forced Gu Xiangtao to produce incense for espionage. He pretended to agree and secretly joined forces with the underground party. In the end, he used life as ink, pine needles and plum branches as guides, and blended the incense of "Mountains and Rivers Are Safe", hiding the information and attachment to his family and country into the fragrance, leaving only Ah Xiu to follow it with his nose. After that, Ah Xiu took the incense spectrum and this bottle of incense, carried out his legacy and passed on information, guarded the incense room, and waited for everything to be safe and for a "reunion in the incense" that spanned life and death with him.
