Modern young man Li Xiaren accidentally traveled to 1978. After inheriting the identity of the original owner, he started a counterattack life with the help of the "two-realm shuttle system". He used modern knowledge and resources to hunt, sell scarce supplies, and establish guesthouses and car dealerships in the past, while at the same time he liquidated antiques and specialties to accumulate capital in the modern era. On the way, he rescued his abused sister, met his wife Qin Xiaoru, made close friends, and fought against evil forces. He also used traditional Chinese medicine to save people and carried out cross-border cooperation with advanced ideas.
