MTL - Harry Potter’s Book of Sin - Chapter 2543 Watch the deadly battle

In the 30th century, Tyler Rustel is an eccentric and visionary genius, renowned as a brilliant inventor. His life, however, comes to an abrupt end when a small experimental nuclear reactor explodes in a series of unforeseen events. Yet, death is not the end for Tyler. He awakens in a body that feels both familiar and foreign—a parallel version of himself in a completely different universe.This is not a world of technological progress or orderly civilization. Here, twisted gods roam the cosmos, shaping realities according to their cruel whims. The moral laws that governed his previous world do not exist. This is a magical universe, one marked by brutal betrayals, interdimensional wars, and endless massacres. The balance between the forces that rule this cosmos is fragile, and Tyler finds himself at the center of schemes involving powerful entities and boundless ambitions.However, Tyler is no longer an ordinary man. Upon awakening in this new world, he discovers that a fragment of his technology has survived with him: an advanced artificial intelligence system capable of analyzing, adapting, and enhancing anything, provided it has the necessary data. From magical weapons and arcane spells to alchemical techniques and enchanted jewelry, everything can be optimized under his supervision.Armed with this technological advantage in a universe dominated by magic, Tyler quickly realizes the potential of his unique position. While others struggle to survive, he schemes to conquer. Driven by his sharp intellect and a questionable sense of morality, Tyler embarks on a ruthless campaign to achieve magical supremacy and subjugate all worlds around him. He seeks neither redemption nor alliances. His ambition is clear: to rule everything and everyone as a tyrant, to amass an immense harem of women, and to father one million children to establish his legacy across all realms.

- Description from Uukanshu translation

My memories of my past life returned when I hit my head on a rock. I am Katarina Claes, the eight-year-old daughter of a Duke. While I was struggling with a high fever, it was decided that I would become a prince’s fiancée. I have now realized that this is the world of an otome game I played in my previous life.

I also realized that I had become the villainous noble girl who got in the way of the protagonist and her capture target… if the protagonist got a good ending, I would be exiled from the country with only the clothes on my back, while in the bad ending, I would be killed by the capture target… where’s my good ending!? Do I only get bad endings!?

I want to overcome all the destruction flags somehow and reach old age!
