Nan Shiqi - an experimenter of the undeveloped space-time shuttle, who was adopted as an experimental subject by a scientist couple for use in time-travel experiments. In the year 2020 in the interstellar world, an experimental virus was leaked, and humanity was in danger. Nan Qi was assigned the last mission - to go back to before all this happened and rewrite history. However, on this last mission, the time shuttle made a mistake. Although he went back to the past, it was not before the virus leaked three years ago, but - 100 years ago.
Concept: a journey through time and space.
