In Shanghai in 1928, the neon lights were on the rise but there was an undercurrent. Lin Wan, a modern independent woman, had her soul travel here after an electric shock accident in a laboratory. She woke up at a pier where people and animals were mixed, her clothes were shabby, and she was being entangled by gangsters. At the critical moment, she was rescued by Shen Yanzhi, who was wearing a black suit and had a cold temperament. Shen Yanzhi, the young leader of the Shanghai Bund Chamber of Commerce, was deeply involved in a fierce business battle with the established families. Seeing that Lin Wan's eyes showed no cowardice of women of that era, but instead revealed a sense of cleverness, he took her back to Shen Mansion for temporary refuge.
Lin Wan quickly accepted the fact of time travel and adapted quickly with modern knowledge. She used simple chemical principles to see through her opponents' product counterfeiting schemes, and proposed novel marketing concepts such as "membership system" and "limited time discounts" to help Shen Yanzhi's department store surpass the rest. Shen Yanzhi gradually fell in love with this woman who always brought surprises, and Lin Wan was also moved by the fact that he sacrificed her life to protect her again and again.
But the good times did not last long. The intervention of the Japanese Chamber of Commerce made the situation increasingly tense, and Shen Yanzhi was falsely accused of collaborating with the enemy. Lin Wan took the risk and sneaked into the Japanese military station, took photos of the evidence with a miniature camera, and united with patriotic student groups to reveal the truth. After the storm, Shen Yanzhi held Lin Wan's hand and said, "In these troubled times, you are the only one who is safe." In the turbulent times, the two used love as their armor to protect their homeland and each other side by side, writing a legend of affection that spans time and space.
Lin Wan not only helped Shen Yanzhi with business advice, but also brought many changes in his life. She taught the servants in the mansion to take care of the house in a more hygienic way, introduced modern cooking techniques, and gave the Shen mansion a completely new look...
