The story tells that thousands of years ago, during the war between the three realms, Qingze, the son of the Qing Emperor, jumped off the immortal platforms to save the human world. His soul turned into countless fragments and fell to the earth. His younger brother Zi Su, in order to revive his brother, ignored the punishment from heaven and was pierced by thousands of bone-piercing nails, and finally came to the human world. Zi Su used incense as a medium to collect the fragments of Qingze's soul, and in a war on the human world, he saved the dying Xinyi and took her as a slave, making her a container for the fragments. The two opened an incense shop named Chengxiangyuan. People with fragments will be led here, and Zi Su will satisfy the wishes of those who seek incense in exchange for fragments. Thus, they experienced ups and downs of love stories and thrilling dream-fulfilling journeys again and again. But at the same time, the villain thug Xuanming, who turned into a national teacher, and the incense-eating beast Hua Ling'er, who drank incense and ate incense, secretly joined forces, calculated everything, and were determined to destroy Zi Su's plan, delay Qingze's resurrection, and attempt to destroy the human world.
