Infinite Time Travel: I Kill Me

I am Xu Feng, and I have a pocket watch in my hand that can travel through time and space at will. I have not been reborn, but in this life, I want to make a new choice, reach the peak of life, and live a perfect life! "But I don't remember the lottery numbers, and I don't remember any big things that have happened around me that can make me rich. How can I get to the top of my life?" And the direction of things seems to be different from what I imagined. Someone killed me, who killed me, and who did I kill? … Did I kill me?
