Spectators Throughout History

This book may have a single female protagonist or no female protagonist. I hate harem stories. I don't know if it's time travel or rebirth. I don't know if it's true or false, I don't know if it comes or goes. Observe the historical changes silently. When Sui Xin takes action, looking back, history is back on track. History cannot be changed, so what is the meaning of my existence? . . . . . . . . . A man returned to the Qin Dynasty with a golden finger that he considered omnipotent and useless. Thinking about changing the world, changing the entire history. But who would have thought that after just waking up from a nap, history would return to its original trajectory. Disappointment again and again made him feel like a spectator, unable to do anything, just an insignificant wave in history. Slowly I learned to be independent and only do what I think I should do. Whether it succeeds or fails, whether it is good or bad, all depends on my own mood. In the end, my only wish is to see if there is an original version of myself in this world. If so, will he be the same as me? . . . . . . This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
