TIME PROXY

I was a high school first semester student who really likes history lessons. At that time, my history study group and I visited ancient locations to dig deeper into the stories that happened in the past and look for historical artifacts that may still remain.
We found a secret entrance which was buried and found some ancient artifacts, but when we were about to get out after taking some artifacts, suddenly an earthquake occurred and buried us, but fate said differently, only I was buried and confined in an ancient cave.
When I opened my eyes, I realized that I was no longer in the same place, I had moved through time.
This is the story of my adventure to return to my time.
