Prince Jinchuan received a secret letter about the sudden death of his mother and concubine. On his way back to the capital, he was ambushed by the prince. After falling off a cliff, he accidentally traveled to 2025. He looks the same as the traffic star Gu Yanchen, and accidentally entered Gu Niuniu's blood orange live broadcast room in Chengxi Village. His costume, appearance, words and deeds attracted attention, and Gu Niuniu chose to take in Jinchuan due to the soaring popularity of the live broadcast. Jinchuan relied on his princely temperament and eloquence to help sell the live broadcast. The two reached a cooperation, and after discovering clues in ancient books in Jinchuan, they explored the method of time travel together.
While studying ancient books, they discovered that mysterious symbols were related to the stars, and speculated that they needed to wear jade pendants to travel through time. During the search for the jade pendant, Jinchuan and Gu Niuniu's relationship warmed up, but Gu Yanchen sent someone to stop them. After many obstacles, the two got the jade pendant and confirmed their relationship. When preparing to travel through time, Gu Yanchen snatched the jade pendant, and the three of them returned to the ancient times where Jinchuan was located.
Back in ancient times, Jinchuan joined forces with Gu Niuniu to rescue Gu Yanchen who was mistakenly arrested before the prince framed him again. Jinchuan relied on modern knowledge to expose the prince's conspiracy and gained the emperor's trust; Gu Niuniu used modern business thinking to open a store and accumulate resources for Jinchuan. The relationship between the two went through the test of court struggle. Jinchuan found out the cause of his mother's death, overthrew the prince and powerful officials, was granted the title of prince, and later married Gu Niuniu.
After becoming the queen, Gu Niuniu developed business. Although she was resisted by the conservative nobles, she resolved the crisis through a series of modern skills. Under the governance of these two people, the country prospered.
