The Day I Came of Age, I Discovered That I Was a Raised Human Being

I died in a car accident. Death is death, and I am alive again. Discovered that a friend was a monster and was eaten. I sensed that the friendly old man downstairs had some clues, so I got mad again. When he became super powerful, he was shocked to realize that this was not the original world at all, but a strange world. Returning to the real world, it suddenly dawned on me that humans were pets kept in captivity. The worldview is refreshed over and over again, so it's better to just die. Dead— Well, it's resurrected again.
