About My Time-Travel Encounter and Time-Travel Time

A man and another man traveled from different eras to modern times, and discovered that they both came from the 21st century. It turned out that the former traveled to the Warring States Period first, lived here for a period of time, and then traveled with another man to the heyday of old Shanghai, and met a male prostitute. There seemed to be some mysterious connection between the three. Ps: There should be a prequel that travels back to the Warring States Period This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
