Rules of the God of Super Seminary

I traveled to ancient times. I dare not change history because I don't understand the rules of time and space. I'm afraid I won't be able to go back. I'm afraid I won't be able to see my family. I have been wandering in history for three thousand years. I have loved before, but it is better not to love. I am immortal and immortal. In the past thousand years, I watched three women I loved die of old age in my arms. One of them begged me to help her live forever together. I did No, because I don't know how my immortality came about. One asked me to leave her, but I couldn't do it because she didn't want me to see her aging face. The other asked me to kill her when she was in her prime. She said that in this way she would always be the most beautiful in my heart. I still couldn't do it, but she still died without a child. Is it the reason for time travel? For the next two thousand years, I wandered in the universe, wandering in emptiness and loneliness. . . Until I came back, I found out that I was wrong. . .
