The Simple Life of Killing Demons - Chapter 40Book 12:

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.

5 years after the world changed, the final boss appeared.

The top five players in the world, including Specter Seo Jun-ho, finally defeated the Frost Queen…

But they fell into a deep slumber.

25 years passed.

“A second floor? It didn’t end when the Frost Queen died?

Specter awakes from his slumber.

The genius pharmacist transmigrated into a pitiful farm girl’s body. Ignored by her own father, abused by her stepmother, and bullied by her stepbrothers. Her “twin” brother was given to distant relative and she went as the “extra” to live under someone else’s roof.

Luckily she possessed mad apothecary skills. Collecting herbs, plowing herb fields, formulating medicines and treating the ills, she refused to live an ordinary life as she slowly uncovered the truth of her real identify.

Inadvertently, she saved a dashing man who was in reality a big, bad wolf hiding under the skin of an innocent little puppy. He pulled out all his tricks: I have no other means to return your favor of saving my life. What say I repay you by marrying you?
