Cheng Shuyi, who is suffering from advanced gastric cancer, travels back to ancient times with his twins to find their biological father, Prince Regent Pei Yanli. Just when the palace welcomed the concubine, she opened "Darun Wanjia" by virtue of the interconnected space between ancient and modern times, and made a lot of money with modern goods. On the way to recognize their relatives, crises such as the concubine's difficulties, the family's contempt, and the rebellion of King Yan were staged one after another. The two solved the misunderstanding six years ago, from testing each other to working together to solve the problem. Pei Yanli did not hesitate to break up with the family to protect his mother and son. Under his protection, Cheng Shuyi also relied on a combination of traditional Chinese and Western medicine to overcome terminal illness. The interesting daily collision of ancient and modern times, the refreshing feeling of raising children and making money, and the deep love running in both directions are intertwined, forming a sweet and intertwined time travel story.
