In the early 1930s, someone came to the Su residence in the suburbs of Shanghai and asked to buy the Su family's antique, a Song Dynasty porcelain pillow. Mr. Su refused sternly and smashed the porcelain pillow to show his determination. His daughter Su Tao came out to clean up, but accidentally found an exquisite bronze mirror among the broken porcelain. She took the bronze mirror back to the attic to play with it out of curiosity, but unexpectedly it triggered a series of strange and bizarre things. In order to make a living, Wuxin took Bai Liuli to set up a stall in front of a casino every day to tell fortunes. On this day, he met Su Tao again. With Wuxin's help, Su Tao finally contacted her brother. She moved into the narrow alley in the slums with Wuxin, and lived a happy and warm life with Wuxin and Bai Niangzi (the little white snake possessed by Bai Liuli), waiting for her brother to return. At this time, Xiao Dingmao, a handsome and androgynous young master of the Chamber of Commerce, broke into the lives of Wuxin and Su Tao. He is the adopted son of a Shanghai gangster. After the gangster fled to Hong Kong, the concession power was divided into two. The underworld business was handed over to the three elders headed by Chen Daguang, and the white chamber of commerce became the world of Xiao Dingmao. He is not as experienced as his age, fighting with Chen Daguang and stirring up trouble; on the other hand, he showed an unusual interest in Wuxin and Su Tao. Shirakawa Rin from Japan suddenly intervened. After several encounters, Bai Liuli underestimated the enemy and was captured, but accidentally discovered the secret of the bronze mirror. Faced with Shirakawa Rin's step-by-step pressure, Wuxin decided to take the initiative. With the help of Xiao Dingmao and Gu Ji's gang forces, he set up a game within a game and destroyed the bronze mirror in Shirakawa Rin's hand. This move could have put him to death, but Gu Ji secretly helped him escape, hoping to exchange it for the position of opium agent. After a period of turmoil, the Yin-Yang master disappeared, Chen Daguang fell, and even Gu Ji left. The days seemed to return to peace. Wuxin took Su Tao with him on an isolated island in the midst of war and depended on each other in the ever-changing situation. Unconsciously, Su Tao's love for Wuxin took root. In the turbulent era, Su Tao and Wuxin were just two tiny dust particles. The gears of fate have begun to turn. Where will they be taken?
