Once crowned, he was immediately told that the most important work of the king is “to welcome the princess from the highest lineage on the continent as your bride”! But then, the beautiful bride who appeared muttered, “gross…” upon seeing his face. Just like that, the new queen began to wage a cold war against Ludwik.

It was a time where demons roamed the earth and chaos reigned. The story took place in Luoyang, the legendary capital of the times. During the night, one could find people holding on to their food with dear lives as they faced off against stray dogs, people with weapons in hand vowing to fight against Fate to their very last breath. There was bloodshed everywhere as some died meaningless deaths, while the strong tyrannized the weak and the truth was frequently hidden. Some of the citizens had completely lost their mind, while some died on their travels. Most importantly, the words of a certain youth caused much panic in the human world.

[WARNING THIS NOVEL IS A SEX NOVEL WHICH INCLUDES SEX CONTENT][Author Note: I have changed the story entirely]Arthur's head hurt like crazy as he woke up. He kept his eyes closed, rubbing his temples and feeling a super comfy bed under him - definitely not his cheap mattress back home.“What the hell...?” he mumbled as he finally looked around.He was in some rich person's bedroom with a fancy four-poster bed and red silk sheets. Sunlight came through pretty stained glass windows, making red patterns on the marble floor.Everything screamed royalty - fancy mirrors, portraits of hunting scenes, and even a painting of a barely-dressed goddess that seemed to be watching him.“How did I get here?” Arthur wondered, getting out of bed. “I definitely drank too much at Mark's party last night”The last thing he remembered was almost getting hit by a car while crossing the street.Looking in a mirror, he got another shock. He didn't look like himself at all! Instead of being skinny with acne scars, he now had muscles, clear skin with just one cool scar on his jaw, with a reddish brown hair, and green eyes.“Damn, I'm hot,” he said, touching the scar.For a moment, he remembered his old life. He pushed up his glasses. Kids made fun of him. Jessica laughed at him when he asked her out. “Like I'd be with a loser like you,” she told him.Suddenly Arthur realized what was happening. “I've been transported to another world! Just like in those stories online!”He spun around excitedly. “I must be someone important here. This is gonna be so cool! Watch out, fantasy world, your new hero has arrived!”Right then, blue text appeared floating in front of him:[System Starting Up...][Host Found: Prince Arthur Lionheart][Soul Check: Person from Another World][Magic Type: Incubus Powers Activated]“Incubus?” Arthur asked in shock. “Like, those demons that seduce people?”[That's right. Your family's magic has changed because of your Earth soul's hidden desires. Congrats on finding your true potential.]“Can I change it? I want to be a cool battle wizard or something!”[Not possible.
