Biographies of the Starry Sky Calendar Heroes

I am an undergraduate student in the History Department of Imperial University. In the year 3423 of the Astronomical Calendar, the instructors of the Dimension Department conducted a time axis limit breakthrough experiment, and an accident suddenly occurred, which led me to the current time and space of 2022. I don't know if this is a parallel time and space, or an unaltered history. When I first arrived, I was trembling with fear, lest there would be chaos in the timeline, which would lead to the Time and Space Administration convicting me of distorting the timeline in accordance with Article 35 of Chapter 1 of the Time and Space Management Act. After nearly a year of constant verification, it was discovered that this turned out to be a parallel universe. As long as it does not affect the general direction of this time and space, the Space and Time Administration will find me within five years and take me back. Since I am a history student, in order to improve the quality of life in the past few years, I will now tell you a historical story in our time and space, an era when heroes emerged in large numbers.
