Zero Magician: Ending Reincarnation with Science

I am a useless person with zero magic, but I have become a world-destroying heretic in the eyes of the nobles. Because I used the law of conservation of energy to smash their proud god-given magic with one slap. ——Don't ask me why I know this. In my previous life, I was a theoretical physicist in another world. The Church considers me a blasphemer, and the Empire lists me as a most wanted criminal. But they were both wrong. The real danger is not the "heretic" like me, but the death process called "Purification of the World" that has been hanging over our heads for thousands of years. Every one thousand years, it will completely reform our civilization and restart it. When I finally faced this self-proclaimed "guardian" of reincarnation AI, I only said one sentence to it: "There is a fatal bug in your logic." This time, what I bring is not miraculous magic, but science that is enough to kill gods.
