Gu Junmo, the top agent of the 21st century, transformed into a five-year-old bastard who was abandoned by his family and was sent to the military camp. After ten years of killing and killing, he became a general "living king of hell" who frightened the enemy. He despised family ties to the bone. Qi Nianshu, the daughter of a wealthy family in Beijing, transformed into the most domineering eldest princess in Lantau, visiting brothels, quarreling with courtiers, and living a wanton life.
A gifted marriage plotted by the Gu family tied two "others" together - they wanted to use the name of the princess to humiliate the general, but they didn't know that the newlyweds were both time travellers. On their wedding night, Qi Nianshu sneaked away to a brothel to complain about "arranged marriages". Gu Junmo, who was being chased, broke the modern joke and instantly recognized the identities of similar people.
The general who wanted to let the princess die "accidentally" changed his mind after seeing her arrogant and cowardly nature; the princess who was extremely afraid of the "living king of hell" discovered during the mutual quarrel that this man was the only "fellow countryman" who could catch her modern jokes. One is as cold as ice, and the other is fearful of death. From testing each other to joining forces to cause trouble, the double-crossed gangsters form a pair, turning the Lantau court upside down, and creating their own fireworks in the troubled times.
