Su Ke, a member of the archaeological club, accidentally touched the general's order during extracurricular practice and traveled to our country. It happened that General Dai Yu was investigating a serial murder case. Su Ke was forcibly married to Dai Yu's mansion by the general's order because she looked exactly like the deceased. However, the capital was undercurrent, and Su Ke was repeatedly assassinated, so he decided to investigate the murderer with Dai Yu. During the investigation, Su Ke met Lu Chen, the young owner of Luli Villa, and met with the emperor of the dynasty. He found that the emperor was Sun Duo, a member of the club who traveled together. It turned out that Su Ke's classmates had traveled to our country, and because of the different time points of the travel, everyone's age and experience were different, and their hearts were also changed. With the help of Sun Duo, Su Ke and Dai Yu successfully found the real murderer and brought him to justice.
