You Have to Make Me a God, Right?

(Not invincible, not systematic, not brainless, not harem, not routine, not cool) After traveling through time, I just thought I was in an ordinary world, until I discovered that everyone around me was a monster, which broke the original peace. I could only pass through the door in my mind, and passed through one "broken" after another, reducing my presence in this world, until I was about to go completely crazy, and finally met the "shepherd" who created this world. I thought it would be the end, but found out that it was annihilation.
