After traversing to the apocalypse, I am extremely delighted as a Demon Cultivator - Chapter 42

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.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

Life Mission – a game that has become reality.

The clock struck midnight when Ruelle heard the echo of footsteps. She tensed, the fine hairs on the back of her neck standing on end in the cool night air.“You shouldn't be here,” Ruelle whispered, her voice a breathless murmur. The silhouette finally came to stand under the moonlight, his dark red eyes watching her and his inky black hair ruffling.“Shouldn't I?” His voice was a dark caress, and she stood there captivated by the danger he exuded like perfume.“I haven’t seen you for the last two days,” his tone low. His hand reached out, fingers brushing against the silk of her nightgown, tracing the trembling outline of her collarbone. “Tell me, were you avoiding me, or perhaps... entertaining other offers?”Ruelle’s heart raced, her breaths shallow. She declared, “I don't belong to anyone.”“A bold claim,“ he murmured, his breath a tantalising chill against her skin as he leaned in. ”Yet here you are, pulse racing, your body tensed as if in anticipation of my touch.”His fingers gripped her chin, tilting her face towards his. The moonlight caught his eyes, revealing a glint of predatory intent. “Or must I remind you whose touch you truly crave?”
