I Have a Ring in the Apocalypse

I accidentally traveled to the past and lived with my parents in this life for three years. I thought things would be like in my previous life, but something happened. When I heard the roar outside the door, I quickly regained my sense and thought about the previous scenes. Suddenly I thought of the biochemical movie I had watched, thinking it was the same as in the movie, but I couldn't find any similarity. I began to look for my parents in this life and my parents in the previous life, experienced fantasy, and established my own team and refuge camp. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
